CHECKING THE ENGINE OIL LEVEL

The dipstick features minimum and maximum marks in order to help determine the oil level present in the engine. The marks can take the form of holes, lines or a hatched area.

Before checking the engine oil level, make sure that:

• The vehicle is stationary and the Electric Parking Brake (EPB) is applied.
• The vehicle is on level ground.
• The engine oil is cold.
  NOTES
  If it is necessary to check the oil level when the engine is hot, switch off the engine. Let the vehicle stand for 5 minutes to allow the oil to drain back into the sump. Do not start the engine.

The oil level is then checked as follows:

1. Withdraw the dipstick and wipe the blade clean with a lint-free cloth.
2. Fully reinsert the dipstick and withdraw again to check the oil level.

If the oil level lies within the hatched portion on the dipstick blade, do not add any more oil.

There is no requirement to top-up the oil unless the oil is at or below the lower mark.

If the oil level is below the lower mark, add 1 L of oil. Recheck the level and add more oil, if necessary.

Once the oil has reached the correct level on the dipstick, wait 5 minutes and recheck.

TOPPING UP THE OIL

• The vehicle’s warranty may be invalidated if damage is caused by using oil that does not meet the required specification. See LUBRICANTS AND FLUIDS.
• Before driving off-road, top up the engine oil level to the maximum mark on the engine oil level dipstick. Failure to do so could result in an insufficient oil level when driving at certain angles off-road, which could cause damage to the engine.
• Failure to use an oil that meets the required specification could cause excessive engine wear, a build up of sludge and deposits, and increase pollution. A resultant cause, could be engine failure.
• Overfilling with oil could result in severe engine damage. Oil should be added in small quantities and the level rechecked to make sure the engine is not overfilled.
• Use of the correct oil specification is essential. Make sure the oil is suitable for the climatic conditions in which the vehicle is to be operated.

1. Turn the oil filler cap counter-clockwise to remove.
2. Add oil to maintain the level between the MIN and MAX marks on the dipstick.
3. Clean up any oil spilled during topping up.
4. Check the oil level again after 5 minutes.
5. Turn the oil filler cap clockwise until a resistance is felt to refit.

CHECKING THE COOLANT LEVEL

Check the coolant reservoir level at least every week. Check more frequently in high mileage or arduous conditions. Always check the level when the system is cold.

Make sure the coolant level remains between the MIN and MAX indicator marks, located on the side of the expansion tank.

If the coolant level has dropped suddenly, or by a large amount, arrange for the vehicle to be examined by qualified personnel. Consult a retailer/authorized repairer as soon as possible.

TOPPING UP THE COOLANT

Antifreeze contains important corrosion inhibitors. The antifreeze content of the coolant must be maintained at 50% to 60% all year round, not just in cold conditions. To make sure the anti-corrosion properties of the coolant are maintained, the antifreeze content should be checked once a year. The antifreeze should be completely replaced every 10 years, regardless of the distance traveled. Failure to do so may cause corrosion of the radiator and engine components. The specific gravity of a 50% antifreeze solution at 68°F (20°C) is 1.068 and protects against frost down to -40°F (-40°C).

To top up the coolant:

1. Rotate the coolant reservoir filler cap counter-clockwise and remove.
2. Top up to the MAX indicator mark on the side of the coolant reservoir. Use a mixture of 50% water and 50% antifreeze. See LUBRICANTS AND FLUIDS.
   CAUTION
   Make sure that the correct mixture of water and antifreeze is used. Failure to do so may cause damage to the vehicle. See LUBRICANTS AND FLUIDS.
   NOTES
   In an emergency, and only if the approved antifreeze is unavailable, top up the cooling system with clean water. Be aware of the resultant reduction in frost protection. Do not top up or refill with conventional antifreeze formulations. If in doubt, consult a qualified technician.
3. To refit the coolant reservoir filler cap, rotate the filler cap clockwise, until the cap’s ratchet clicks at least three times.

CHECKING THE BRAKE FLUID LEVEL

• Seek qualified assistance immediately if brake pedal travel is unusually long, or if there is any significant loss of brake fluid. Driving under such conditions could result in extended stopping distances or complete brake failure.
• Brake fluid is highly toxic. Keep containers sealed and out of the reach of children. If accidental consumption of fluid is suspected, seek medical attention immediately.
• If the fluid comes into contact with the skin or eyes, rinse immediately with plenty of clean water.
• Brake fluid is highly flammable. Do not allow brake fluid to come into contact with open flames, a hot engine, or other sources of ignition. A fire may result.
• Do not drive the vehicle with the fluid level below the MIN mark.
• If the quantity of fluid in the brake reservoir drops below the recommended level, a red warning lamp in the instrument panel illuminates. See BRAKE (RED).

With the vehicle on level ground, check the fluid level at least every week. Check more frequently in high mileage or arduous operating conditions.

To check the brake fluid level:

1. Remove the driver’s side under-hood cover. See UNDER-HOOD COVERS REMOVAL.
2. Check the brake fluid level in the reservoir. The level should be between the MIN and the MAX marks.

TOPPING UP THE BRAKE FLUID

CAUTION

• Always use brake fluid which has the correct specification. See LUBRICANTS AND FLUIDS.
• Brake fluid damages painted surfaces. Soak up any spillage with an absorbent cloth immediately. Wash the area with a mixture of car shampoo and water.
• Only use new fluid from an airtight container. Fluid from open containers, or fluid previously bled from the system, would have absorbed moisture. Contaminated fluid adversely affects performance, and must not be used.
• Do not top up the brake fluid to the maximum mark unless the brake pads have been replaced. If unsure, seek qualified assistance.

To top up the brake fluid:

1. Clean the brake fluid reservoir and the filler cap before removing, to prevent dirt from entering the reservoir.
2. Rotate the reservoir filler cap counter-clockwise and remove.
3. Top up the reservoir to at least the minimum mark.
4. Rotate the reservoir filler cap clockwise to refit.
5. Refit the under-hood cover. See UNDER-HOOD COVERS REFITTING.

CHECKING THE WASHER FLUID LEVEL

WARNING
Some windshield washer products are flammable, particularly if high or undiluted concentrations are exposed to sparking. Do not allow windshield washer fluid to come into contact with exposed flames or sources of ignition, as this can cause a fire or explosion.

WARNING
If the vehicle is operated in temperatures below 40°F (4°C), use a windshield washer fluid with frost protection. In cold weather, failure to use a windshield washer fluid with frost protection could result in impaired vision and increase the risk of a vehicle crash.

CAUTION

• Do not use antifreeze or vinegar and water solution in the windshield washer reservoir. Antifreeze damages painted surfaces, while vinegar can damage the windshield washer pump.
• Body panels may suffer discoloration as a result of windshield washer fluid spillage. Take care to avoid spillage, particularly if an undiluted or high concentration is being used. If spillage occurs, wash the affected area immediately with water.
• Only use approved windshield washer fluid.
• The washer fluid reservoir supplies the windshield, rear window and headlight washer jets.

Check and top up the reservoir level at least every week. Always top up with windshield washer fluid to prevent freezing.

Operate the washer controls periodically to check that the nozzles are clear and properly directed.

TOPPING UP THE WASHER FLUID

The washer fluid reservoir is located under the hood on the right side of the vehicle. See FLUID FILLER LOCATIONS.

To top up the washer fluid:

1. Clean the filler cap before removing, it to prevent dirt from entering the reservoir.
2. Remove the filler cap.
3. Top up the reservoir until the fluid is visible in the filler neck.
4. Replace the filler cap.

Cold climate vehicles also feature a supplemental washer reservoir. The same care points, described above, should be applied to vehicles fitted with a supplemental washer reservoir.

NOTES
On vehicles fitted with a supplemental washer reservoir, always check and top up the main reservoir first.
