● 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 thoroughl y

the vehicle. Make sure to extend the mirrors before driving.
● Brushes used in automatic car washes may scratch the vehicle su rface,
parts (wheel, etc.) and harm your vehicle’s paint.
● In certain automatic car washes, the roof antenna may interfere with
machine operation. This may prevent the vehicle from being clea ned prop-
erly or result in damage to the antenna.

• Do not use detergent on the wheels when they are hot, such as after driv-
ing or parking in hot weather
■ Brake pads and calipers
Rust may form if the vehicle is parked with wet brake pads or d isc rotors,

Exhaust gases cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe unti l it has
cooled sufficiently, as touching hot exhaust pipe can cause burns.
