●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wash soap and rinse thoroughly
with water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is
cool.

●Fold the mirrors before washing the vehicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface and harm
your vehicle’s paint.
●Rear spoiler (if equipped) may not be washable in some automatic car washes.
There may also be an increased risk of damage to vehicle.

●Do not allow the nozzles of the car wash to come within close proximity of the win-
dows.
●Before using the car wash, check that the fuel filler door on your vehicle is closed
properly.

the door may lock and unlock repeatedly. In that case, follow the following correc-
tion procedures to wash the vehicle:
●Place the key in a position 6 ft. (2 m) or more separate from the vehicle while the
vehicle is being washed. (Take care to ensure that the key is not stolen.)
