the knobs to the lock position.
Do not put additional floor mats on top of 
the anchored mat.
Vacuum dirt and dust from the leather frequently. Pay close attention to the pleats 
and seams. Clean the leather with a soft cloth dampened with a 90% water and 
10% neutral soap solution. Then buff it with a clean, dry cloth. Remove any dust or 
dirt on leather surfaces immediately.

Exterior CareDust off the vehicle body after you drive.
Regularly inspect your vehicle for  scratches 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.
• Do not spray high pressure water directly into the engine compartment. Instead, 
use low pressure water and a mild detergent. ■

A good coat of automotive body wax helps protect your vehicle’s paint from the 
elements. Wax will wear off over time and exp ose 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. Promptly wipe it away using a soft cloth and 
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road 
contaminants. Use a sponge and mild detergent to wipe away promptly.
Be careful not to use harsh chemicals (including 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.■
