Only dinghy tow four-wheel-drive vehicles
that have an N (Neutral) and a Four-Wheel
Drive Low (4 (

1. Position the vehicle being towed behind the tow vehicle, facing forward and on a
level surface.
2. Securely attach the vehicle being towed to the tow vehicle.
3. Apply the parking brake and start the engine.
4. Shift the transfer case to N (Neutral). See “Shifting into N (Neutral)” under

vehicle is in N (Neutral) by shifting the
transmission to R (Reverse) and then to
D (Drive). There should be no movement
of the vehicle while shifting.

304 Vehicle Care
Steering, Suspension, and Chassis
Components
Visually inspect steering, suspension, and
chassis components for damaged, loose,
or missing parts or signs of wear at least
once a year.
Inspect power steering for proper
attachment, connections, binding, leaks,
cracks, chafing, etc.
Visually check constant velocity joint boots
and axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders, hood hinges,
liftgate hinges, steel fuel door hinge, and
power assist step 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. Refer to
“Finish Care”previously in
this section.
Interior Care
To prevent dirt particle abrasions, regularly
clean the vehicle's interior. Immediately
remove any soils. Newspapers or dark
garments can transfer color to the vehicle’s
interior.
Use a soft bristle brush to remove dust from
knobs and crevices on the instrument
cluster. Using a mild soap solution,
immediately remove hand lotions,
sunscreen, and insect repellent from all
interior surfaces or permanent damage may
result.
Use cleaners specifically designed for the
surfaces being cleaned to prevent
permanent damage. Apply all cleaners
directly to the cleaning cloth. Do not spray
cleaners on any switches or controls.
Remove cleaners quickly.
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.
