Do not operate the starter longer than 30 seconds. Wait at least
two minutes between starting attempts to allow the starter to
cool. If the engine does not start after several attempts, call for
road service.
Removing the jumper cables
1. Remove the ground connection
from the disabled vehicle first,
followed by the cable on the
negative (-) battery terminal of the
booster vehicle.
2. Remove the cable from the
positive (+) terminal of the
discharged battery and then from
the positive (+) terminal of the
booster battery.
3. After the disabled vehicle has
been started, allow it to idle for a
while so the engine can“relearn”its
idle conditions.
WRECKER TOWING
Always unload your vehicle before towing it. The recommended method
of towing is with the drive wheels off the ground.
Before towing, make sure:
•the parking brake is released.
•if air pressure has been lost, to release the brakes manually.
Improper towing of the vehicle will not allow sufficient lubrication of the
transmission which may cause serious damage to internal transmission
components. Always follow the outlined towing procedures.
•To tow a vehicle on the front wheels,the steering wheel must be
in the straight ahead position. Secure the steering wheel with a
holding device (such as provided by a towing company).

•To tow a vehicle on the rear wheels,it will be necessary to remove
the drive axles or disconnect the driveshaft. If the drive axles are
removed, the ends of the axle housing must be sealed to prevent the
loss of axle lubricant during towing.
•To tow a vehicle with an inoperative rear axle,the rear wheels
must be raised onto a dolly or tow the vehicle on the front wheels.
•If your vehicle is equipped with tow hooks,chains must be
fastened directly to the tow hooks on the vehicle.
•If your vehicle is not equipped with tow hooks,chains must be
routed under the bottom edge of the bumper with a protection bar to
protect the bumper, and attached to the vehicle chassis. Under no
circumstances is the vehicle to be lifted or towed by attaching chains
directly to the bumper.
Raising the vehicle
Never lift the vehicle by the bumper. When raising the vehicle, attach
chains to or place the jack(s) directly beneath the main structural
members of the vehicle.
Push-starting your vehicle
Avoid attempting to start a vehicle by pushing. Instead, use jumper
cables as described underJump starting your vehiclein this chapter.
Vehicles with an automatic transmission cannot be started by pushing.

WASHING THE EXTERIOR
Wash your vehicle regularly with cool or lukewarm water and a neutral
Ph shampoo, such as Detail Wash (ZC-3–A), which is available from your
dealer.
•Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
•Never wash a vehicle that is“hot to the touch”or during exposure to
strong, direct sunlight.
•Always use a clean sponge or carwash mitt with plenty of water for
best results.
•Dry the vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
•It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
•Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle’s
paintwork and trim over time.
•Remove any exterior accessories, such as antennas, before entering a
car wash.
•Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle,
wash off as soon as possible.
WAXING
Applying a polymer paint sealant to your vehicle every six months will
assist in reducing minor scratches and paint damage.
•Wash the vehicle first.
•Do not use waxes that contain abrasives.
•Do not allow paint sealant to come in contact with any non-body
(low-gloss black) colored trim, such as grained door handles, roof
racks, bumpers, side moldings, mirror housings or the windshield cowl
area. The paint sealant will“gray”or stain the parts over time.
