2022 Hyundai Tucson Braking System User Manual

2022 Hyundai Tucson Braking System

BRAKING SYSTEM

Power-assist brakes

Your vehicle has power-assisted brakes that adjust automatically through normal usage.  If the engine is not running or is turned off while driving, the power assist for the brakes will not work. You can still stop your vehicle by applying greater force to the brake pedal than typical. The stopping distance, however, will be longer than with power brakes. When the engine is not running, the reserve brake power is partially depleted each time the brake pedal is applied. Do not pump the brake pedal when the power assist has been interrupted.

WARNING

Take the following precautions:

• Do not drive with your foot resting on the brake pedal. This will create abnormal high brake temperatures, excessive brake lining, and pad wear, and increased stopping distances.
• When descending down a long or steep hill, use the paddle shifter and manually downshift to a lower gear in order to control your speed without using the brake pedal excessively. Applying the brakes continuously will cause the brakes to overheat and could result in a temporary loss of braking performance.
• Wet brakes may impair the vehicle’s ability to safely slow down; the vehicle may also pull to one side when the brakes are applied. Applying the brakes lightly will indicate whether they have been affected in this way. Always test your brakes in this fashion after driving through deep water. To dry the brakes, lightly tap the brake pedal to heat up the brakes while maintaining a safe forward speed until brake performance returns to normal. Avoid driving at high speeds until the brakes function correctly.

Disc brakes wear indicator

• When your brake pads are worn and new pads are required, you will hear a high-pitched warning sound from your front or rear brakes. You may hear this sound come and go or it may occur whenever you depress the brake pedal.
• Note that some driving conditions or climates may cause a brake squeal when you first apply (or lightly apply) the brakes. This is normal and does not indicate a problem with your brakes.

NOTICE
To avoid costly brake repairs, do not continue to drive with worn brake pads.

Information
Always replace brake pads as complete front or rear axle sets.

Electronic Parking Brake (EPB)

Applying the parking brake

To apply EPB (Electronic Parking Brake)

Anti-lock Brake System (ABS)

WARNING
Anti-Lock Braking System (ABS) or Electronic Stability Control (ESC) system will not prevent accidents due to improper or dangerous driving maneuvers. Even though vehicle control is improved during emergency braking, always maintain a safe distance between you and objects ahead of you. Vehicle speeds should always be reduced during extreme road conditions. The braking distance for vehicles equipped with ABS or ESC may be longer than for those without these systems in the following road conditions. Drive your vehicle at reduced speeds
during the following conditions:

• Rough, gravel or snow-covered roads.
• On roads where the road surface is pitted or has different surface heights.
• Tire chains are installed on your vehicle.

The safety features of an ABS or ESC-equipped vehicle should not be tested by high-speed driving or cornering. This could endanger the safety of yourself or others.

ABS is an electronic braking system that helps prevent a braking skid. ABS allows the driver to steer and brake at the same time.

Using ABS

• To obtain the maximum benefit from your ABS in an emergency situation, do not attempt to modulate your brake pressure and do not try to pump your brakes. Depress your brake pedal as hard as possible.
• When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ABS is active.
• ABS does not reduce the time or distance it takes to stop the vehicle.
• Always maintain a safe distance from the vehicle in front of you.
• ABS will not prevent a skid that results from sudden changes in direction, such as trying to take a corner too fast or making a sudden lane change. Always drive at a safe speed for the road and weather conditions.
• ABS cannot prevent a loss of stability. Always steer moderately when braking hard. Severe or sharp steering wheel movement can still cause your vehicle to veer into oncoming traffic or off the road.
• On loose or uneven road surfaces, the operation of the anti-lock brake system may result in a longer stopping distance than for vehicles equipped with a conventional brake system.
• The ABS ( ) warning light will stay on for several seconds after the Engine Start/Stop button is in the ON position.
• During that time, ABS will go through self-diagnosis and the light will go off if everything is normal. If the light stays on, you may have a problem with your ABS. We recommend that you contact an authorized HYUNDAI dealer as soon as possible.

WARNING

If the ABS warning light is on and stays on, you may have a problem with the ABS. Your power brakes will work normally. To reduce the risk of serious injury or death, contact your authorized HYUNDAI dealer as soon as possible.

NOTICE

• When you drive on a road having poor traction, such as an icy road, and apply your brakes continuously, ABS will be active continuously and the ABS ( ) warning light may illuminate. Pull your vehicle over to a safe place and turn the vehicle off.
• Restart the vehicle. If the ABS warning light is off, then your ABS system is normal.
• Otherwise, you may have a problem with your ABS system. We recommend that you contact an authorized HYUNDAI dealer as soon as possible.

Information

When you jump-start your vehicle because of a drained battery, the ABS  warning light may turn on at the same time. This happens because of the low battery voltage. It does not mean your ABS is malfunctioning. Has the battery been recharged before driving the vehicle?

Electronic Stability Control (ESC)

• Electronic Stability Control helps to stabilize the vehicle during cornering maneuvers.
• ESC checks where you are steering and where the vehicle is actually going. ESC applies braking pressure to any one of the vehicle’s brakes and intervenes in the engine management system to assist the driver with keeping the vehicle on the intended path. It is not a substitute for safe driving practices. Always adjust your speed and driving to the road conditions.

WARNING

• Never drive too fast for the road conditions when cornering. ESC will not prevent accidents.
• Excessive speed in turns, abrupt maneuvers, and hydroplaning on wet surfaces can result in severe accidents.

ESC operation

ESC ON condition

When the Engine Start/Stop button is in the ON position, ESC and the ESC OFF indicator lights illuminate for approximately three seconds. After both lights go off, ESC is enabled.

When operating

When ESC is in operation, the ESC indicator light blinks

• When you apply your brakes under conditions that may lock the wheels, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your ESC is active.
• When ESC activates, the engine may not respond to the accelerator as it does under routine conditions.
• If Cruise Control was in use when ESC activates, Cruise Control automatically disengages. Cruise Control can be reengaged when the road conditions allow. See the “Cruise Control (CC)” section in chapter 7 (if equipped).
• When moving out of the mud or driving on a slippery road, the engine RPM (revolutions per minute) may not increase even if you press the accelerator pedal deeply. This is to maintain the stability and traction of the vehicle and does not indicate a problem.

ESC OFF condition

To cancel ESC operation

1. State 1 Press the ESC OFF button briefly. TheESC OFF indicator light and/or message  ‘Traction Control disabled’ will illuminate. In this state, the traction control function of ESC (engine management) is disabled, but the brake control function of ESC (braking management) still operates.
2. State 2 Press and hold the ESC OFF button continuously for more than 3 seconds. The ESC OFF indicator light and/or message ‘Traction & Stability Control disabled’ illuminates and a warning chime sounds. In this state, both the traction control function of ESC (engine management) and the brake control function of ESC (braking management) are disabled.
   1. If the Engine Start/Stop button is pressed to the OFF position when ESC is off, ESC remains off. Upon restarting the vehicle, ESC will automatically turn on again.

Indicator lights

• When the Engine Start/Stop button is pressed to the ON position, the ESC indicator light illuminates, then goes off if the ESC system is operating normally.
• The ESC indicator light blinks whenever ESC is operating.
• If the ESC indicator light stays on, your vehicle may have a malfunction with the ESC system. When this warning light illuminates we recommend that the vehicle be checked by an authorized HYUNDAI dealer as soon as possible. The ESC OFF indicator light comes on when ESC is turned off.

WARNING

When ESC is blinking, this indicates ESC is active: Drive slowly and NEVER attempt to accelerate. NEVER turn ESC off while the ESC indicator light is blinking or you may lose control of the vehicle resulting in an accident.

NOTICE

Driving with wheels and tires of different sizes may cause the ESC system to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive a vehicle with different-sized wheels and tires installed.

ESC OFF usage

When Driving

• The ESC OFF mode should only be used briefly to help free the vehicle if stuck in snow or mud, by temporarily stopping the operation of the ESC, to maintain wheel torque.
• To turn ESC off while driving, press the ESC OFF button while driving on a flat road surface.

NOTICE

To prevent damage to the transmission:

• Do not allow wheel(s) of one axle to spin excessively while the ESC, ABS, and Parking Brake warning lights are displayed. The repairs would not be covered by the vehicle warranty. Reduce engine power and do not spin the wheel(s) excessively while these lights are displayed.
• When operating the vehicle on a dynamometer, make sure ESC is turned off (ESC OFF light illuminated).

Information

Turning ESC off does not affect ABS or standard brake system operation.

Vehicle Stability Management (VSM)

Vehicle Stability Management is a function of the Electronic Stability Control (ESC) system. It helps the vehicle stay stable when accelerating or braking suddenly on wet, slippery, and rough roads where traction over the four tires can suddenly become uneven.

WARNING

Take the following precautions when using Vehicle Stability Management:

• ALWAYS check the speed and the distance to the vehicle ahead. VSM is not a substitute for safe driving practices.
• Never drive too fast for the road conditions. VSM will not prevent accidents. Excessive speed in bad weather, and on slippery and uneven roads, can result in severe accidents.

VSM operation

When operating When you apply your brakes under conditions that may activate ESC, you may hear sounds from the brakes, or feel a corresponding sensation in the brake pedal. This is normal and it means your VSM is active.

Information

VSM does not operate when:

• Driving on a banked road such as gradient or incline.
• Driving in reverse.
• The ESC OFF indicator light is on.
• The EPS (Electric power steering) warning light  is on or blinks.

VSM OFF condition

• To cancel the VSM operation, press the ESC OFF button. ESC OFF ( ) indicator light will illuminate.
• To turn on VSM, press the ESC OFF button again. The ESC OFF indicator light will go out.

WARNING

If the ESC ( ) indicator light or EPS  warning light stays illuminated or blinks, your vehicle may have a malfunction with the VSM system. When the warning light illuminates we recommend that the vehicle be checked by an authorized HYUNDAI dealer as soon as possible.

NOTICE

Driving with wheels and tires of different sizes may cause the VSM system to malfunction. Before replacing tires, make sure all four tires and wheels are the same size. Never drive a vehicle with different sized tires and wheels installed.

Trailer stability assist (TSA)

Trailer stability assist is operated as a vehicle stability control system. The Trailer stability assist system stabilizes the vehicle and trailer when the trailer sways or oscillates. There are various reasons for making vehicles sway and oscillate. In most cases it happens at high speed however, if the trailer is affected by crosswinds, buffeting, and improper overloading, it may also be a risk of sway.

Factors of swaying such as:

• High speed
• Strong crosswinds
• Improper overloading
• Sudden controlling of the steering wheel
• Uneven road

The trailer stability assist system continuously analyzes the vehicle and trailer instability. When the Trailer stability assist system detects some sway, the brakes are applied automatically to stabilize the vehicle on the front wheel. However, if it is not enough to stabilize, the brakes are applied on all wheels automatically and engine power is properly reduced. When the vehicle is stable from swaying, the trailer stability assist system does not operate.

Hill-Start Assist Control (HAC)

Hill-Start Assist Control helps prevent the vehicle from rolling backward when starting a vehicle from a stop on a hill. The system operates the brakes automatically for approximately 2 seconds and releases when the accelerator pedal is depressed.

WARNING

Always be ready to depress the accelerator pedal when starting off an incline. Hill-Start Assist Control activates only for approximately 2 seconds. Information

• Hill-Start Assist Control does not operate when the gear is shifted to P (Park) or N (Neutral).
• Hill-Start Assist Control activates eve when the ESC (Electronic Stability Control) is off. However, it does not activate, when ESC does not operate normally.

Downhill Brake Control (DBC)

• Downhill Brake Control assists the driver to descend down a steep hill without having to depress the brake pedal. The system automatically applies the brakes to maintain vehicle speed below a certain speed and allows the driver to concentrate on steering the vehicle downhill.
• The system is turned off whenever the engine is turned off.
• Press the button to turn on the system and press the button again to turn it off.

• Downhill Brake Control may not always maintain vehicle speed at a certain speed.
• Downhill Brake Control does not operate when:
  • The gear is in P (Park).
  • ESC is activated.
• Noise or vibration may occur from the brakes when Downhill Brake Control is activated.
• The rear stop light comes on when Downhill Brake Control is activated.

Good braking practices

WARNING

Whenever leaving the vehicle or parking, always come to a complete stop and continue to depress the brake pedal. Shift the gear to the P (Park) position, then apply the parking brake, and press the Engine Start/Stop button to the OFF position Vehicles parked with the parking brake not applied or not fully engaged may roll inadvertently and may cause injury to the driver and others. ALWAYS apply the parking brake before exiting the vehicle.

• Wet brakes can be dangerous! The brakes may get wet if the vehicle is driven through standing water or if it is washed. Your vehicle will not stop as quickly if the brakes are wet. Wet brakes may cause the vehicle to pull to one side.
• To dry the brakes, apply the brakes lightly until the braking action returns to normal. If the braking action does not return to normal, stop as soon as it is safe to do so and we recommend that you call an authorized HYUNDAI dealer for assistance.
• DO NOT drive with your foot resting on the brake pedal. Even light, but constant pedal pressure can result in the brakes overheating, brake wear, and possibly even brake failure.
• If a tire goes flat while you are driving, apply the brakes gently and keep the vehicle pointed straight ahead while you slow down. When you are moving slowly enough for it to be safe to do so, pull off the road and stop in a safe location. Keep your foot firmly on the brake pedal when the vehicle is stopped to prevent the vehicle from rolling forward.
