392 Vehicle Care
Underbody Maintenance
Caution
Avoid pressure washing the vehicle frame.
Use of high-pressure washers can result
in removal of corrosion protection and
possible vehicle damage.
At least twice ayear, spring and fall, use plain
wa
ter to flush any corrosive materials from the
underbody. Take care to thoroughly clean any
areas where mud and other debris can collect. If
equipped with power assist steps, extend them
and then use ahigh pressure wash to clean all
joints and gaps.
Do not directly pressure wash the transfer
case and/or front/rear axle output seals. High
pressure water can overcome the seals and
contaminate the fluid. Contaminated fluid will
decrease the life of the transfer case and/or
axles and should be replaced.
Sheet Metal Damage
If
the vehicle is damaged and requires sheet
metal repair or replacement, make sure
the body repair shop applies anti-corrosion
material to parts repaired or replaced to restore
corrosion protection.
Original manufacturer replacement parts
will provide the corrosion protection while
maintaining the vehicle warranty.
Finish Damage
Quickly repair minor chips and scratches with
touch-up materials available from your dealer
to avoid corrosion. Larger areas of finish
damage can be corrected in your dealer's body
and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall upon and attack
painted vehicle surfaces causing blotchy, ring-
shaped discolorations, and small, irregular dark
spots etched into the paint surface. See “Finish
Care” previously in this section.
Interior Care
To
prevent dirt particle abrasions, regularly
clean the vehicle's interior. Before using
cleaners, read and follow all safety instructions
on the label. While cleaning the interior,
open the doors and windows to get proper
ventilation. Newspapers or dark garments can
transfer color to the vehicle’s interior.
Caution
Immediately remove cleaners, hand
lo
tions, sunscreen, and insect repellent
from all interior surfaces or permanent
damage may result.
Caution
Use cleaners specifically designed for
t
h
e surfaces being cleaned to prevent
permanent damage to the vehicle. Apply all
cleaners directly to a cleaning cloth. Do not
spray cleaners on any switches or controls.
When using liquid soap cleaners, follow the
d
i
rections on the specific cleaner or soap
solution for dilution instructions.
