Tires
Use a stiff brush with tire cleaner to
clean the tires.
Caution
Using petroleum-based tire
dressing products on the vehicle
may damage the paint finish and/
or tires. When applying a tire
dressing, always wipe off any
overspray from all painted
surfaces on the vehicle.
Wheels and Trim Aluminum
or Chrome
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and other chrome
trim may be damaged if the
vehicle is not washed after driving
on roads that have been sprayed
with magnesium, calcium,
or sodium chloride. These
chlorides are used on roads for
conditions such as ice and dust.
Always wash the chrome with
soap and water after exposure.
Caution
To avoid surface damage, do not
use strong soaps, chemicals,
abrasive polishes, cleaners,
brushes, or cleaners that
contain acid on aluminum or
chrome-plated wheels. Use only
approved cleaners.

Vehicle Care
Caution (Continued)
Also, never drive a vehicle with
aluminum or chrome-plated
wheels through an automatic car
wash that uses silicone carbide
tire cleaning brushes. Damage
could occur and the repairs would
not be covered by the vehicle
warranty.
Steering, Suspension, and
Chassis Components
Visually inspect the front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect hydraulic
power steering systems for proper
hook-up, binding, leaks, cracks,
chafing, etc. Visually check constant
velocity joints, rubber boots, and
axle seals for leaks.
