WARNING!Do not connect trailer brakes to your vehicle ’ s hy-
draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.
Towing any trailer will increase your stopping dis-
tance. When towing you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.
Towing Requirements — Trailer Lights & Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may includ ea4and7pin
wiring harness. Use a factory approved trailer harness
and connector. NOTE: Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following illustrations.

Towing Tips — Electronic Speed Control (If
Equipped)
Don ’ t use in hilly terrain or with heavy loads.
When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips — Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
Highway Driving
Reduce speed. Air Conditioning
Turn off temporarily.
refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Recreational towing for this vehicle is not recommended.
NOTE: If the vehicle requires towing make sure all four

6. These locations are on the sill flange of the body and
consist of a pair of downstanding tabs. The jack is to be
located, engaging the flange, between the pair of tabs
closest to the wheel to be changed. Place the wrench on
the jack screw and turn to the right until the jack head is
properly engaged in the described location. Do not raise
the vehicle until you are sure the jack is securely
engaged.
7. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability. WARNING!Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
8. Remove the wheel lug nuts, for vehicles with wheel
covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
9. Install the compact spare tire. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has been
lowered.
NOTE: Do not install the wheel cover on the compact
spare.
Do not use a hammer or force to install the wheel covers.376 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “ Malfunction Indicator Light. ” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible. CAUTION!• Prolonged driving with the “ Malfunction Indica-
tor Light ” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
• If the “ Malfunction Indicator Light ” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.398 MAINTAINING YOUR VEHICLE

The external lock cylinders should be lubricated twice a
year, preferably in the fall and spring. Apply a small
amount of a high quality lubricant such as Mopar  Lock
Cylinder Lubricant directly into the lock cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc. Windshield and Rear Window Washers
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the engine
compartment and should be checked for fluid level at
regular intervals. Fill the reservoir with windshield
washer solvent (not radiator antifreeze) and operate the
system for a few seconds to flush out the residual water.
The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates.414 MAINTAINING YOUR VEHICLE

replaced immediately! Eventual deterioration of the hose
can take place resulting in a possibility of a burst failure.
WARNING!Worn brake hoses can burst and cause brake failure.
You could have an accident. If you see any signs of
cracking, scuffing, or worn spots, have the brake
hoses replaced immediately.
Master Cylinder — Brake Fluid Level Check
The fluid level in the master cylinder should be checked
when performing underhood services, or immediately if
the brake system warning light indicates system failure.
Clean the top of the master cylinder area before removing
the cap. Add fluid to bring the level up to the top of the
“ FULL ” mark on the side of the master cylinder reservoir. Overfilling of fluid is not recommended because it may
cause leaking in the system.
Add enough fluid to bring the level up to the require-
ments described on the brake fluid reservoir. With disc
brakes, fluid level can be expected to fall as the brake
pads wear. However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only manufacturers recommended brake fluid, refer
to Fluids, Lubricants and Genuine Parts for correct fluid
type.
WARNING!Use of brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident. MAINTAINING YOUR VEHICLE 423
