Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer in an area away from heavy
traffic.
Towing Tips — Automatic Transmission
The “D” range can be selected when towing. However,
if frequent shifting occurs while in this range, the “3”
range should be selected.Using the “3” range while
operating the vehicle under heavy operating conditions
will improve performance and extend transmission life
by reducing excessive shifting and heat build up. This
action will also provide better engine braking.
The automatic transmission fluid and filter should be changed if you REGULARLY tow a trailer for more than 45
minutes of continuous operation. See Schedule “B” in section 8 of this manual for transmission fluid change inter-
vals.
NOTE: Check the automatic transmission fluid level before towing.
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 — Autostick (If Equipped)
− For vehicles equipped with Autostick. By using the Autostick modes, and selecting a specific gear range, fre-
quent shifting can be avoided. The highest gear range should be selected that allows for adequate performance.
For example, choose “4” if the desired speed can be maintained. Choose “3” or “2” if needed to maintain the
desired speed.
− Extended driving at high RPM should be avoided to prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at high RPM. Return to a higher gear range or vehicle speed
when road conditions and RPM level allows.
Towing Tips — Cooling System
To reduce potential for engine and transmission overheating, take the following actions:
•
City Driving - When stopped for short periods of time, put transmission in neutral and 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 information.

DESCRIPTION
ESP and Power assist four wheel disc brakes are
standard equipment. Disc brake components consist
of single piston calipers and ventilated rotors. Rear
disc brakes use a drum in hat design for the parking
brake which is activated by brake shoes pressing
against the inside of the drum in hat rotor (1).
The parking brake mechanism is lever and cable oper-
ated. The cables (2) are attached to equalizers on the
rear disc brake support plate which moves the park
brake shoes firmly against the drum in hat rotor. The
parking brakes are operated by a hand lever.
The vehicle is equipped with ESP (Electronic Stability
Program). There are four wheel speed sensors, one
sensor at each wheel to monitor input.
A dual diaphragm vacuum power brake booster is
used for all applications. All models have an aluminum
master cylinder with plastic reservoir.
Factory brake lining on all models consists of an
organic base material combined with metallic particles. The original equipment linings do not contain asbestos.
WARNING
WARNING: Dust and dirt accumulating on brake parts during normal use may contain asbestos fibers from
aftermarket linings. Breathing excessive concentrations of asbestos fibers can cause serious bodily harm.
Exercise care when servicing brake parts. Do not clean brake parts with compressed air or by dry brushing.
Use a vacuum cleaner specifically designed for the removal of asbestos fibers from brake components. If a
suitable vacuum cleaner is not available, cleaning should be done with a water dampened cloth. Do not
sand, or grind brake lining unless equipment used is designed to contain the dust residue. Dispose of all
residue containing asbestos fibers in sealed bags or containers to minimize exposure to yourself and oth-
ers. Follow practices prescribed by the occupational safety and health administration and the environmental
protection agency for the handling, processing, and disposition of dust or debris that may contain asbestos
fibers.
CAUTION: Never use gasoline, kerosene, alcohol, motor oil, transmission fluid, or any fluid containing min-
eral oil to clean the system components. These fluids damage rubber cups and seals. Use only fresh brake
fluid or Mopar brake cleaner to clean or flush brake system components. These are the only cleaning mate-
rials recommended. If system contamination is suspected, check the fluid for dirt, discoloration, or separa-
tion into distinct layers. Also check the reservoir cap seal for distortion. Drain and flush the system with
new brake fluid if contamination is suspected.
CAUTION: Use Mopar brake fluid, or an equivalent quality fluid meeting SAE/DOT standards J1703 and DOT
3. Brake fluid must be clean and free of contaminants. Use fresh fluid from sealed containers only to ensure
proper antilock component operation.
CAUTION: Use Mopar multi-mileage or high temperature grease to lubricate caliper slide surfaces, drum
brake pivot pins, and shoe contact points on the backing plates. Use multi-mileage grease or GE 661 or
Dow 111 silicone grease on caliper slide pins to ensure proper operation.
