Vehicle Care 10-73
{WARNING
Rust or dirt on a wheel, or on
the parts to which it is fastened,
can make wheel nuts become
loose after time. The wheel could
come off and cause an accident.
When changing a wheel, remove
any rust or dirt from places where
the wheel attaches to the vehicle.
In an emergency, use a cloth or a
paper towel to do this; but be sure
to use a scraper or wire brush
later, if needed, to get all the rust
or dirt off. SeeIf a Tire Goes Flat
on page 10‑81.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on
the wheel nuts or bolts.
If your vehicle has a Tire
Pressure Monitor System
(TPMS), reset the TPMS
sensors after rotating the tires.
See
Tire Pressure Monitor
Operation
on page 10‑67.
Make sure the spare tire,
if your vehicle has one, is stored
securely. Push, pull, and then
try to rotate or turn the tire.
If it moves, tighten the cable.
See “Storing a Flat or Spare Tire
and Tools” underTire Changing
on page 10‑83.
Dual Tire Rotation
When the vehicle is new,
or whenever a wheel, wheel
bolt or wheel nut is replaced,
check the wheel nut torque
after 160, 1 600 and 10 000 km
(100, 1,000 and 6,000 miles) of
driving. For proper torque and wheel
nut tightening information, see
“Removing the Spare Tire and
Tools” underTire Changing
on
page 10‑83.

right front of the engine, where
the negative battery cable
attaches.
If your vehicle has a diesel
engine, the remote negative (−)
terminal is the negative (−) post

For more information on
the location of the remote
positive (+) and remote
negative (−) terminals, see

{WARNING
An electric fan can start up even
when the engine is not running
and can injure you. Keep hands,
clothing and tools away from any
underhood electric fan.
{WARNING
Using an open flame near a
battery can cause battery gas to
explode. People have been hurt
doing this, and some have been
blinded. Use a flashlight if you
need more light.
Be sure the battery has enough
water. You do not need to add
water to the battery installed in
your new vehicle. But if a battery
has filler caps, be sure the right(Continued)
WARNING (Continued)
amount of fluid is there. If it is low,
add water to take care of that
first. If you do not, explosive gas
could be present.
Battery fluid contains acid that
can burn you. Do not get it on
you. If you accidentally get it in
your eyes or on your skin, flush
the place with water and get
medical help immediately.
{WARNING
Fans or other moving engine
parts can injure you badly. Keep
your hands away from moving
parts once the engine is running.

6. Use an adequate clampingdevice designed for towing to
ensure that the front wheels are
locked into the straight position.
{WARNING
Shifting a four-wheel-drive
vehicle's transfer case into
N (Neutral) can cause the vehicle
to roll even if the transmission is
in P (Park). The driver or others
could be injured. Make sure the
parking brake is firmly set before
the transfer case is shifted to
N (Neutral).
7. Shift the transfer case to N (Neutral). See “Shifting into
Neutral” underFour-Wheel Drive
on page 9‑53for the proper
procedure to select the neutral
position for the vehicle.
8. Turn the ignition to LOCK/OFF.
After towing, see “Shifting Out of
Neutral” underFour-Wheel Drive
on
page 9‑53.
Appearance Care
Exterior Care
Silicone grease on weatherstrips will
make them last longer, seal better,
and not stick or squeak. Apply
silicone grease with a clean cloth.
During very cold, damp weather
frequent application may be
required. See Recommended Fluids
and Lubricants on page 11‑8.
Washing the Vehicle
The best way to preserve the
vehicle's finish is to keep it clean
by washing it often.
Notice: Certain cleaners contain
chemicals that can damage the
emblems or nameplates on the
vehicle. Check the cleaning
product label. If it states that it
should not be used on plastic
parts, do not use it on the vehicle
or damage may occur and it
would not be covered by the
warranty. Do not wash the vehicle in direct
sunlight. Use a car washing soap.
Do not use cleaning agents that
are petroleum based or that contain
acid or abrasives, as they can
damage the paint, metal or plastic
on the vehicle. Approved cleaning
products can be obtained from your
dealer. Follow all manufacturers'
directions regarding correct
product usage, necessary safety
precautions and appropriate
disposal of any vehicle care
product.
Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
