To keep the system operating properly, be
sure to observe the following:
∙ Always keep the sensor area of the front bumper clean.
∙ Do not strike or damage the areas around the sensor.
∙ Do not cover or attach stickers or similar objects on the front bumper near the sen-
sor area. This could cause failure or mal-
function.

10.Keeping your Vehicle Cool
∙ Park your vehicle in a covered parking area or in the shade whenever pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C system. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases tire
wear and lowers fuel economy.
∙ Keep all the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer in-
formation” section of this manual. If any malfunction occurs in the Intelligent
AWD system while the engine is running,
messages are displayed in the meter.
