Mexico-16402009) - 2023 - CRC - 3/28/22
Vehicle Care 333
Visually check constant velocity joint boots
and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
liftgate hinges, and the steel fuel door
hinges, unless the components are plastic.
Applying silicone grease on weatherstrips
with a clean cloth will make them last
longer, seal better, and not stick or squeak.
Underbody Maintenance
At least twice a year, spring and fall, use
plain water to flush any corrosive materials
from the underbody. Take care to
thoroughly clean any areas where mud and
other debris can collect.
Do not directly power 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
lotions, sunscreen, and insect repellent
from all interior surfaces or permanent
damage may result.
Caution
Use cleaners specifically designed for the
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
directions on the specific cleaner or soap
solution for dilution instructions.
Caution
To prevent damage:
.Never use a razor or any other sharp
object to remove soil from any interior
surface
.Never use a brush with stiff bristles.(Continued)
