Your vehicle is equipped with the Adaptive Cruise Control (ACC) system which will adjust the vehicle speed up to the preset speed to maintain a distance with the vehicle ahead.
NOTE:
In vehicles NOT equipped with the Active Driving Assist (ADA) system:
Adaptive Cruise Control (ACC) increases the driving convenience provided by Cruise Control while traveling on highways and major roadways. However, it is not a safety system and not designed to prevent collisions.
ACC will allow you to keep Cruise Control engaged in light to moderate traffic conditions without the constant need to reset your Cruise Control. ACC utilizes a radar sensor and a forward facing camera designed to detect a vehicle directly ahead of you.
NOTE:
WARNING!
Adaptive Cruise Control (ACC) Operation
The buttons on the right side of the steering wheel operate the ACC system.
The instrument cluster display will show the current system settings for Adaptive Cruise Control (ACC), Active Lane Management (ALM), and the Active Driving Assist (ADA) systems. The information it displays depends on ACC, ALM, and ADA system statuses.
Pushing the Adaptive Cruise Control (ACC) buttons will display one of the following messages in the instrument cluster display:
Adaptive Cruise Control Ready
When ACC is activated but the vehicle speed setting has not been selected, the display will read “Adaptive Cruise Control Ready.”
Adaptive Cruise Control Set
When the SET (+) or the SET (-) button is pushed, the display will read “ACC: XX mph (km/h)”.
When ACC is set, the set speed will show in the instrument cluster display.
The ACC screen may display once again if any of the following ACC activity occurs:
Adaptive Cruise Control Off
When ACC is deactivated, the display will read “Adaptive Cruise Control Off”.
The instrument cluster display will return to the last display selected after five seconds of no ACC display activity.
Activating Adaptive Cruise Control (ACC)
The minimum set speed for the ACC system is 20 mph (32 km/h).
When the system is turned on and in the ready state, the instrument cluster display will read “ACC Ready.”
When the system is off, the instrument cluster display will read “Adaptive Cruise Control (ACC) Off.”
NOTE:
You cannot engage ACC under the following conditions:
To Activate/Deactivate
Push and release the Adaptive Cruise Control
(ACC) on/off button. The ACC menu in the instrument cluster displays “ACC Ready.”
To turn the system off, push and release the Adaptive Cruise Control (ACC) on/off button again. At this time, the system will turn off and the instrument cluster displays “Adaptive Cruise Control (ACC) Off.”
WARNING!
Leaving the Adaptive Cruise Control (ACC) system on when not in use is dangerous. You could accidentally set the system or cause it to go faster than you want. You could lose control and have a collision. Always leave the system off when you are not using it.
To Set A Desired Speed
When the vehicle reaches the speed desired, push the SET (+) button or the SET (-) button and release. The instrument cluster display will show the set speed.
NOTE:
Fixed Speed Cruise Control (if equipped) is used without ACC enabled. To change between Adaptive Cruise Control (ACC) and Fixed Speed Cruise Control features, first turn off ACC by pushing the ACC on/off button. Then, turn on Fixed Speed Cruise Control by pushing the Fixed Speed Cruise Control on/off button.
WARNING!
In Fixed Speed Cruise Control mode, the system will not react to vehicles ahead. In addition, the proximity warning does not activate and no alarm will sound even if you are too close to the vehicle ahead since neither the presence of the vehicle ahead nor the vehicle-to-vehicle distance is detected. Be sure to maintain a safe distance between your vehicle and the vehicle ahead. Always be aware which mode is selected.
If ACC is set when the vehicle speed is below 20 mph (32 km/h), the set speed will default to 20 mph (32 km/h).
NOTE:
Fixed Speed Cruise Control cannot be set below 20 mph (32 km/h).
If either system is set when the vehicle speed is above 20 mph (32 km/h), the set speed shall be the current speed of the vehicle.
NOTE:
To Cancel
The following conditions cancel the ACC or Fixed Speed Cruise Control systems:
The following conditions will only cancel the ACC system:
The system will turn off and erase the set speed in memory if:
To Resume
If there is a set speed in memory, push the RES (resume) button and remove your foot from the accelerator pedal. The instrument cluster display will show the last set speed.
Resume can be used at any speed above 20 mph (32 km/h) when only Fixed Speed Cruise Control is being used.
Resume can be used at any speed above 0 mph (0 km/h) when ACC is active.
NOTE:
WARNING!
The Resume function should only be used if traffic and road conditions permit. Resuming a set speed that is too high or too low for prevailing traffic and road conditions could cause the vehicle to accelerate or decelerate too sharply for safe operation. Failure to follow these warnings can result in a collision and death or serious personal injury.
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set speed by pushing the SET (+) button, or decrease speed by pushing the SET (-) button.
U.S. Speed (mph)
Metric Speed (km/h)
NOTE:
When you override and push the SET (+) button or SET (-) button, the new set speed will be the current speed of the vehicle.
When ACC Is Active
The specified following distance for ACC can be set by varying the distance setting between four bars (longest), three bars (long), two bars (medium) and one bar (short). Using this distance setting and the vehicle speed, ACC calculates and sets the distance to the vehicle ahead. This distance setting appears in the instrument cluster display.
To increase the distance setting, push the Distance Increase button and release. Each time the button is pushed, the distance setting increases by one bar (longer).
To decrease the distance setting, push the Distance Decrease button and release. Each time the button is pushed, the distance setting decreases by one bar (shorter).
If there is no vehicle ahead, the vehicle will maintain the set speed. If a slower moving vehicle is detected in the same lane, the instrument cluster display will show the ACC Set With Target Detected Indicator Light, and the system will adjust the vehicle speed automatically to maintain the distance setting, regardless of the set speed.
The vehicle will then maintain the set distance until:
The maximum braking applied by ACC is limited; however, the driver can always apply the brakes manually, if necessary.
NOTE:
The brake lights will illuminate whenever the ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC predicts that its maximum braking level is not sufficient to maintain the set distance. If this occurs, a visual alert “BRAKE!” will flash in the instrument cluster display and a chime will sound while ACC continues to apply its maximum braking capacity.
NOTE:
The “BRAKE!” screen in the instrument cluster display is a warning for the driver to take action and does not necessarily mean that the Forward Collision Warning system is applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) engaged and following a vehicle, the system will provide an additional acceleration up to the ACC set speed to assist in passing the vehicle. This additional acceleration is triggered when the driver utilizes the left turn signal and will only be active when passing on the left hand side.
If the ACC system brings your vehicle to a standstill while following a vehicle ahead, your vehicle will resume motion, without any driver interaction, if the vehicle ahead starts moving within two seconds of your vehicle coming to a standstill.
If the vehicle in front does not start moving within two seconds of your vehicle coming to a standstill, the driver will either have to push the RES (resume) button, or apply the accelerator pedal to reengage the ACC to the existing set speed.
NOTE:
WARNING!
When the ACC system is resumed, the driver must ensure that there are no pedestrians, vehicles or objects in the path of the vehicle. Failure to follow these warnings can result in a collision and death or serious personal injury.
“WIPE FRONT RADAR SENSOR IN FRONT OF VEHICLE” WARNING
The “ACC Unavailable Wipe Front Radar Sensor” warning will display and a chime will sound when conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as in snow or heavy rain. The ACC system may also become temporarily blinded due to obstructions, such as mud, dirt or ice. In these cases, the instrument cluster display will display the above message and the system will deactivate.
This message can sometimes be displayed while driving in highly reflective areas (i.e. ice and snow, or tunnels with reflective tiles). The ACC system will recover after the vehicle has left these areas. Under rare conditions, when the radar is not tracking any vehicles or objects in its path this warning may temporarily occur.
NOTE:
If the “ACC Unavailable Wipe Front Radar Sensor” warning is active, Fixed Speed Cruise Control is still available.
If weather conditions are not a factor, the driver should examine the sensor. It may require cleaning or removal of an obstruction. The sensor is located in the center of the vehicle behind the lower grille.
To keep the ACC System operating properly, it is important to note the following maintenance items:
When the condition that deactivated the system is no longer present, the system will return to the “Adaptive Cruise Control Off” state and will resume function by simply reactivating it.
NOTE:
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC Limited Functionality Clean Front Windshield” warning will display, and a chime will sound when conditions temporarily limit system performance. This most often occurs at times of poor visibility, such as in snow or heavy rain and fog. The ACC system may also become temporarily blinded due to obstructions, such as mud, dirt, or ice on windshield and fog on the inside of glass. In these cases, the instrument cluster display will read “ACC Limited Functionality Clean Front Windshield” and the system will have degraded performance.
This message can sometimes be displayed while driving in adverse weather conditions. The ACC system will recover after the vehicle has left these areas. Under rare conditions, when the camera is not tracking any vehicles or objects in its path this warning may temporarily occur. If weather conditions are not a factor, the driver should examine the windshield and the camera located on the back side of the inside rearview mirror. They may require cleaning or removal of an obstruction.
When the condition that created limited functionality is no longer present, the system will return to full functionality.
NOTE:
If the “ACC Limited Functionality Clean Front Windshield” message occurs frequently (e.g. more than once on every trip) without any snow, rain, mud, or other obstruction, have the windshield and forward facing camera inspected at an authorized dealer.
SERVICE ACC WARNING
If the system turns off, and the instrument cluster display reads “ACC Unavailable Service Required” or “Cruise Unavailable Service Required”, there may be an internal system fault or a temporary malfunction that limits ACC functionality. Although the vehicle is still drivable under normal conditions, ACC will be temporarily unavailable. If this occurs, try activating ACC again later, following an ignition cycle. If the problem persists, see an authorized dealer.
In certain driving situations, ACC may have detection issues. In these cases, ACC may brake late or unexpectedly. The driver needs to stay alert and may need to intervene. The following are examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that is offset from your direct line of travel, or a vehicle merging in from a side lane. There may not be sufficient distance to the vehicle ahead. The offset vehicle may move in and out of the line of travel, which can cause your vehicle to brake or accelerate unexpectedly.
TURNS AND BENDS
When driving on a curve with ACC engaged, the system may decrease the vehicle speed and acceleration for stability reasons, with no vehicle in front detected. Once the vehicle is out of the curve the system will resume your original set speed. This is a part of normal ACC system functionality.
NOTE:
On tight turns ACC performance may be limited.
USING ACC ON HILLS
When driving on hills, ACC may not detect a vehicle in your lane. Depending on the speed, vehicle load, traffic conditions, and the steepness of the hills, ACC performance may be limited.
LANE CHANGING
ACC may not detect a vehicle until it is completely in the lane in which you are traveling. In the following lane changing example, ACC has not yet detected the vehicle changing lanes and it may not detect the vehicle until it is too late for the ACC system to take action. ACC may not detect a vehicle until it is completely in the lane. There may not be sufficient distance to the lane-changing vehicle. Always be attentive and ready to apply the brakes if necessary.
NARROW VEHICLES
Some narrow vehicles traveling near the outer edges of the lane or edging into the lane are not detected until they have moved fully into the lane. There may not be sufficient distance to the vehicle ahead.
STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or vehicles. For example, ACC will not react in situations where the vehicle you are following exits your lane and the vehicle ahead is stopped in your lane. It will consider this stopped vehicle a stationary object as it did not previously detect movement from it. Always be attentive and ready to apply the brakes if necessary.
