Vehicle Care 9-79
1. The vehicle used to jump startmust have 12-volt battery with a
negative ground.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. The vehicles should be close enough for the jumper cables to
reach, but the vehicles should
not be touching. Touching could
cause grounding and possible
electrical system damage.
Put both vehicles in P (Park)
and set the parking brake firmly.
3. Unplug accessories plugged into the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that are
not needed. Turn off the ignition
on both vehicles. 4. Locate the positive (+) and
negative (−) terminals on both
vehicles. Some vehicles have
remote jump starting terminals.
{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. 5. The remote positive (+)
terminal (A) is located on the
underhood fuse block, on the
driver side. Lift the red cap to
uncover the terminal.
The remote negative (−)
terminal (B) is a stud behind the
metal tab stamped with GND (−)
near the driver side strut tower.
6. The jumper cables should be in good working condition with no
loose or missing insulation. The
vehicles could be damaged if
they are not.
7. Connect the red positive (+) cable to the positive (+) terminal
on the vehicle with the dead
battery. Use a remote
positive (+) terminal if the
vehicle has one.

8. Do not let the other end touchmetal. Connect it to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the vehicle
has one.
9. Connect the black negative (−) cable to the negative (−) terminal
of the good battery. Use a
remote negative (−) terminal if
the vehicle has one.
Do not let the other end touch
anything until the next step. The
other end of the negative (−)
cable does not go to the dead
battery. It goes to a heavy,
unpainted metal engine part or
to a remote negative (−) terminal
on the vehicle with the dead
battery.
10. Connect the other end of the negative (−) cable away from
the dead battery, but not near
engine parts that move. 11. Start the vehicle with the good
battery and run the engine.
12. Press the unlock symbol on the remote keyless entry
transmitter to disarm the
security system, if equipped.
13. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it needs
service.
Notice: If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct
order, making sure that the
cables do not touch each other or
other metal.

Towing the Vehicle
To avoid damage, the disabled
vehicle should be towed with all four
wheels off the ground. Consult your
dealer/retailer or a professional
towing service if the disabled
vehicle must be towed. See
Roadside Assistance Program
on
page 12‑6.
To tow the vehicle behind
another vehicle for recreational
purposes —such as behind a
motorhome, see Recreational
Vehicle Towing following.
Recreational Vehicle
Towing
Recreational vehicle towing means
towing the vehicle behind another
vehicle –such as behind a
motorhome. The two most common
types of recreational vehicle towing
are known as dinghy towing and
dolly towing. Dinghy towing is
towing the vehicle with all four
wheels on the ground. Dolly towing
is towing the vehicle with two
wheels on the ground and two
wheels up on a device known as
a dolly.

9-82 Vehicle Care
Here are some important things to
consider before recreational vehicle
towing:
.What is the towing capacity of
the towing vehicle? Be sure to
read the tow vehicle
manufacturer's
recommendations.
.What is the distance that will be
travelled? Some vehicles have
restrictions on how far and how
long they can tow.
.Is the proper towing equipment
going to be used? See your
dealer/retailer or trailering
professional for additional advice
and equipment
recommendations.
.Is the vehicle ready to be
towed? Just as preparing the
vehicle for a long trip, make sure
the vehicle is prepared to be
towed.
Dinghy Towing
Front-wheel‐drive and
all-wheel-drive vehicles may 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. For other towing options,
see“Dolly Towing” following in this
section.
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.
To tow the vehicle from the front
with all four wheels on the ground:
1. Position the vehicle that will be towed and secure it to the
towing vehicle.
2. Turn the ignition key to ACC/ ACCESSORY.
3. Shift the transmission to N (Neutral).

Vehicle Care 9-83
4. Turn all accessories off.
5. To prevent the battery fromdraining while the vehicle is
being towed, remove fuse 32,
the Discrete Logic Ignition
Switch fuse, from the instrument
panel fuse block and store it in a
safe location. See Instrument
Panel Fuse Block on page 9‑42.
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 has been
reached:
1. Set the parking brake.
2. Shift the transmission to
P (Park).
3. Turn the ignition key to LOCK/OFF.
4. Install fuse 32, the Discrete Logic Ignition Switch fuse. See
Instrument Panel Fuse Block
on
page 9‑42.
5. Start the engine and let it idle for more than three minutes before
driving the vehicle.
Notice: Too much or too
little fluid can damage the
transmission. Be sure that the
transmission fluid is at the proper
level before towing with all four
wheels on the ground. 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 should 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.

9-84 Vehicle Care
Dolly Towing
(Front-Wheel‐Drive Vehicles)
To tow the vehicle from the front
with the rear wheels on the ground,
do the following:
1. Put the front wheels on a dolly.
2. Move the shift lever to P (Park).
3. Set the parking brake. 4. Secure the vehicle to the dolly.
5. Follow the dolly manufacturer's
instructions for preparing the
vehicle and dolly for towing.
6. Release the parking brake.
Towing the Vehicle From
the Rear
Notice: Towing the vehicle from
the rear could damage it. Also,
repairs would not be covered by
the vehicle warranty. Never have
the vehicle towed from the rear.

Vehicle Care 9-85
Appearance Care
Exterior Care
Cleaning Exterior Lamps/
Lenses
Use only lukewarm or cold water, a
soft cloth and a car washing soap to
clean exterior lamps and lenses.
Follow instructions under“Washing
the Vehicle” later in this section.
Finish Care
Occasional waxing or mild polishing
of the vehicle by hand may be
necessary to remove residue from
the paint finish. Approved cleaning
products can be obtained from your
dealer/retailer. If the vehicle has a basecoat/
clearcoat paint finish, the clearcoat
gives more depth and gloss to the
colored basecoat. Always use
waxes and polishes that are
non-abrasive and made for a
basecoat/clearcoat paint finish.
Notice:
Machine compounding
or aggressive polishing on a
basecoat/clearcoat paint finish
may damage it. Use only
non-abrasive waxes and polishes
that are made for a basecoat/
clearcoat paint finish on the
vehicle.
Foreign materials such as calcium
chloride and other salts, ice melting
agents, road oil and tar, tree sap,
bird droppings, chemicals from
industrial chimneys, etc., can
damage the vehicle's finish if they
remain on painted surfaces. Wash
the vehicle as soon as possible. If necessary, use non-abrasive
cleaners that are marked safe for
painted surfaces to remove foreign
matter.
Exterior painted surfaces are
subject to aging, weather and
chemical fallout that can take their
toll over a period of years. To keep
the paint finish looking new, keep
the vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal
Parts
Bright metal parts should be
cleaned regularly to keep their
luster. Wash with water or use
chrome polish on chrome or
stainless steel trim, if necessary.
Use special care with aluminum
trim. To avoid damaging protective
trim, never use auto or chrome
polish, steam or caustic soap to
clean aluminum. A coating of
wax, rubbed to high polish, is
recommended for all bright
metal parts.

9-86 Vehicle Care
Washing the Vehicle
To preserve the vehicle's finish,
keep it clean by washing it often.
Do not wash the vehicle in
direct sunlight and use a car
washing soap.
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 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/retailer. Follow all
manufacturer 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.
High pressure car washes could
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 30 cm (12 inches) to
the surface of the vehicle. Use of
power washers exceeding
8,274 kPa (1,200 psi) can result
in damage or removal of paint and
decals.
Notice:
Conveyor systems on
some automatic car washes could
damage the vehicle. There may
not be enough clearance for the
undercarriage. Check with the car
wash manager before using the
automatic car wash.
Weatherstrips
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 10‑7.
