5. Tilt the retainer and slip itthrough the wheel opening to
remove the spare tire from the
cable.
6. Turn the wrench clockwise to raise the cable back up after
removing the spare tire.
Do not store a full‐size or a flat
road tire under the vehicle.
See “Storing the Spare Tire”
and “Storing the Flat Tire” later
in this section.
Removing the Flat Tire and
Installing the Spare Tire
1. Do a safety check before proceeding. See If a Tire Goes
Flat on page 10‑58 for more
information.
2. If the vehicle has a wheel cover, loosen the plastic nut caps with
the wheel wrench. They will not
come off. Then, using the flat
end of the wheel wrench, pry
along the edge of the cover until
it comes off. Be careful; the
edges may be sharp. Do not try
to remove the cover with your
bare hands.
Store the wheel cover securely
in the rear of the vehicle until
you have the flat tire repaired or
replaced.
If the vehicle has aluminum
wheels, remove the wheel nut
caps using the wheel wrench.
3. Loosen the wheel nuts —but do
not remove them —using the
wrench. For wheels with a wheel
lock key, use the wheel lock key
between the lock nut and
wrench. The key is supplied in
the front passenger door pocket.

{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, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.

Dinghy Towing
If the vehicle is front-wheel‐drive, it
can be dinghy towed from the front.
These vehicles may also be towed
by putting the front wheels on a
dolly. See“Dolly Towing” later in this
section. If the vehicle is all‐wheel‐drive, it
can be dinghy towed from the front.
These vehicles can also be towed
by placing them on a platform trailer
with all four wheels off of the
ground. These vehicles cannot be
towed using a dolly.
For vehicles being dinghy towed,
the vehicle should be run at the
beginning of each day and at each
RV fuel stop for about five minutes.
This will ensure proper lubrication of
transmission components. Reinstall
the fuse to start the vehicle.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle to be
towed, shift the transmission to
P (Park), and turn the ignition
to LOCK/OFF.
2. Secure the vehicle to the towing vehicle.
3. Set the parking brake.
4. Turn the ignition to ACC/ACCESSORY.
5. Shift the transmission to N (Neutral).

6. To prevent the battery fromdraining while the vehicle is
being towed, remove the
20 amp ECM1 fuse and the
50 amp BATT1 fuse from the
underhood fuse block and store
in a safe location. See Engine
Compartment Fuse Block on
page 10‑31.
7. Release the parking brake.
Notice: If the vehicle is towed
without performing each of the
steps listed under “Dinghy
Towing,” the automatic
transmission could be damaged.
Be sure to follow all steps of the
dinghy towing procedure prior to
and after towing the vehicle.
Notice: If 105 km/h (65 mph) is
exceeded while towing the
vehicle, it could be damaged.
Never exceed 105 km/h (65 mph)
while towing the vehicle. Once the destination is reached:
1. Set the parking brake.
2. Reinstall the fuses in the
underhood fuse block.
3. Shift the transmission to P (Park), turn the ignition to
LOCK/OFF and remove the key
from the ignition.
4. Disconnect the vehicle from the towing vehicle.
Notice: Do not tow a vehicle with
the front drive wheels on the
ground if one of the front tires is
a compact spare tire. Towing with
two different tire sizes on the
front of the vehicle can cause
severe damage to the
transmission.Dolly Towing (All-Wheel‐Drive
Vehicles)
All-wheel‐drive vehicles must not be
towed with two wheels on the
ground. To properly tow these
vehicles, they should be placed on
a platform trailer with all four wheels
off of the ground or dinghy towed
from the front.

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.
Keep the wheels clean using a soft,
clean cloth with mild soap and
water. Rinse with clean water.
After rinsing thoroughly, dry with a
soft, clean towel. A wax may then
be applied.
Notice: 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. Notice:
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. 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 front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect the power
steering for proper hook-up, binding,
leaks, cracks, chafing, etc. Visually
check constant velocity joints,
rubber boots, and axle seals for
leaks.
Body Component Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and the
steel fuel door hinge 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
Use plain water to flush dirt and
debris from the vehicle's underbody.
Your dealer or an underbody car
washing system can do this. If not
removed, rust and corrosion can
develop.
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.
