Exterior Care
Dust off the vehicle body after you drive.
Regularly inspect your vehicle for scra tches on painted surfaces. A scratch on a
painted surface can result in body rust. If you find a scratch, promptly repair it.
Wash the vehicle regularly. Wash more frequently when driving in the following
conditions:
• If driving on roads with road salt.
• If driving in coastal areas.
• If tar, soot, bird droppings, insects, or tree sap are stuck to painted surfaces.
Fold in the door mirrors.
Make sure to follow the instructions indicated on the automated car wash.
• Keep sufficient distance between the cleaning nozzle and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.

Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time an d expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin coated parts, they
may be stained or the coating may peel. Prom ptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deteriorat ion caused by salt and other road
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (inc luding some commercial wheel cleaners) or
a stiff brush. They can damage the clear coat of the aluminum alloy wheels that
helps keep the aluminum from corroding and tarnishing.

Maintenance
The inside lenses of exterior lights (headlights, brake light s, etc.) may fog temporarily
if you have driven in the rain, or after the vehicle has been run through a car wash.
Dew condensation also may build up inside the lenses when there is a significant
enough difference between the ambient and inside lens temperatures (similar to
vehicle windows fogging up in rainy conditions).
These conditions are natura l processes, not structural design problems in the
exterior lights.
Lens design characteristics ma y result in moisture developing on the light lens frame
surfaces. This also is not a malfunction.
However, if you see large amounts wate r accumulation, or large water drops
building up inside the lenses, have your vehicle inspected by a dealer.
