To Activate:
Push the speed control lever inward (toward
the steering column) and release (“ON/OFF”).
The indicator light in the lever (and in the
instrument cluster on some models) will illu-
minate to show that the speed control system is ON. To
turn the system OFF, push the lever inward (toward the
steering column) again and release. At this time, the
system and the indicator light will turn off.
WARNING!
Leaving the Electronic Speed Control system on
when not in use is dangerous. You could accidentally
set the system or cause it to go faster than you want.
You could lose control and have an accident. Always
leave the system OFF when you aren’t using it.
To Set At A Desired Speed:
When the vehicle reaches the speed desired, push the
lever down and release (“SET/DECEL”). Remove your
foot from the accelerator pedal and the vehicle will
operate at the selected speed.
NOTE:
•
Speed control will only function in third, fourth, or
fifth gear when in the AutostickMode (if equipped).
•The speed control may not engage if a different size
tire is installed on one wheel, such as the compact
spare tire.
To Deactivate:
The system will disable Electronic Speed Control without
erasing the memory if you:
•Softly tap the brake pedal.
•Depress the brake pedal.
•Push the speed control lever away from you (“CAN-
CEL”).
Pushing and releasing the lever (“ON/OFF”) or turning
off the ignition erases the set speed from memory.
To Resume Speed:
If you deactivated the speed control without erasing the
set speed from memory and your vehicle speed is above
20 mph (32 km/h) you can resume the previous set

vehicle placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire
inflation pressure for those tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires are significantly under-inflated. Ac-
cordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a
significantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more tire pressures is low. The
Tire Pressure Monitoring Telltale Light will flash on and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
condition is removed and reset. (See page 254 for more
information.)
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. After-market wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.

CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the front differential and/or
the transfer case.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the rear wheels to pull errati-
cally to the right or left. This phenomenon occurs when
there is a difference in the surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is danger-
ous. Unequal traction can cause sudden pulling of
the rear wheels. You could lose control of the vehicle
and possibly have an accident. Accelerate slowly and
carefully whenever there is likely to be poor traction
(ice, snow, wet mud, loose sand, etc.).
Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is known as hydroplaning and may cause
partial or complete loss of vehicle control and stopping
ability. To reduce this possibility, the following precau-
tions should be observed:
1. Slow down during rainstorms or when the roads are
slushy.
2. Slow down if road has standing water or puddles.
3. Replace tires when tread wear indicators first become
visible.
4. Keep tires properly inflated.
5. Maintain sufficient distance between your vehicle and
the vehicle in front to avoid a collision in a sudden stop.

WARNING!
•The Anti-Lock Brake System contains sophisticated
electronic equipment that may be susceptible to inter-
ference caused by improperly installed or high output
radio transmitting equipment. This interference can
cause possible loss of anti-lock braking capability. In-
stallation of such equipment should be performed by
qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly on
your brake pedal when you need to slow down or stop.
•Anti-lock system (ABS) cannot prevent the natural laws
of physics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires or the
traction afforded.
•The ABS cannot prevent accidents, including those
resulting from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic

WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, and braking of your vehicle. This can cause
unpredictable handling and stress to steering and
suspension components. You could lose control
and have an accident resulting in serious injury or
death. Use only the tire and wheel sizes with load
ratings approved for your vehicle.
•Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Alignment And Balance
Poor suspension alignment may result in:
•Fast tire wear.
•Uneven tire wear, such as feathering and one-sided
wear.
•Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.
Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.

SELF–SEALING TIRES — IF EQUIPPED
A non-hardening viscous sealant applied to the inner
liner of each tire fills punctures up to 0.19 in. (5 mm) to
minimize the loss of air pressure. This contributes to the
safety of the vehicle by significantly reducing the prob-
ability of a roadside stop due to a flat tire.
TIRE CHAINS
Use only compact chains, or other traction aids that meet
SAE type “Class S” specifications. Chains must be the
proper size for the vehicle, as recommended by the chain
manufacturer.
NOTE:Do not use tire chains on a compact spare tire.
CAUTION!
To avoid damage to your vehicle or tires, observe the
following precautions:
•Because of restricted chain clearance between tires
and other suspension components, it is important
that only chains in good condition are used. Broken
chains can cause serious damage. Stop the vehicle
immediately if noise occurs that could indicate chain
breakage. Remove the damaged parts of the chain
before further use.
•Install chains on the rear wheels as tightly as pos-
sible and then retighten after driving about12mile
(0.8 km).
•Do not exceed 30 mph (48 km/h).
•Drive cautiously and avoid severe turns and large
bumps, especially with a loaded vehicle.
•Use on Rear Wheels only.
•Do not drive for prolonged period on dry pavement.
•Observe the tire chain manufacturer’s instructions on
the method of installation, operating speed, and con-
ditions for use. Always use the lower suggested
operating speed of the chain manufacturer if different
from the speed recommended by the manufacture.

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the

can cause sensor damage. Do not use tire sealant
from a can, or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors

•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
•
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale light.
