Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer. TSC activates automatically once
the excessively swaying trailer is recognized. When TSC
is functioning, the “ESC Light” will flash, the engine
power will be reduced, and you will feel the brake being
applied to individual wheels in an attempt to stop the
trailer from swaying.
NOTE:The TSC is disabled when the ESC system is in
the “Partial Off” mode.
WARNING!
•TSC cannot stop all trailers from swaying. Always
use caution when towing a trailer and follow the
tongue weight recommendations. Refer to ”Ve-
hicle Loading” and “Trailer Towing” in “Starting
and Operating” for further information.
(Continued)
WARNING! (Continued)
•If TSC activates while towing a trailer, stop the
vehicle at the nearest safe location and adjust the
trailer load to eliminate the trailer sway.
•Failure to follow these warnings can result in a
collision or serious personal injury.
Hill Start Assist (HSA)
The HSA system is designed to assist the driver when
starting a vehicle from a stop on a hill. HSA will maintain
the level of brake pressure the driver applied for a short
period of time after the driver ’s foot is removed from the
brake pedal. If the driver does not apply the throttle
during this short period of time, the system will release
brake pressure and the vehicle can roll after brake
pressure is released. The system will release brake pres-
sure in proportion to the amount of throttle applied as
the vehicle starts to move in the intended direction of
travel.

Hill Start Assist Disable Procedure
NOTE:Vehicle roll back mitigation will not be present
with this feature disabled.
Hill Start assist can be disabled if desired. This procedure
applies to vehicles equipped with a manual or Powertech
transmission.
1. Wheels must be pointed straight ahead, on a level
surface.
2. Automatic transmission should be in PARK.
3. Place manual transmission in NEUTRAL if equipped
4. Begin with the ignition OFF.
5. Engage park brake.
6. Start engine and wait for ESC OFF lamp to turn off.
7. Apply brake pedal. 8. Turn steering wheel 200 degrees counter clockwise,
just over half a turn from center position. Press the
ESC
off button 4 times.
9. Rotate the steering wheel back to center and continue
in a clockwise direction until 200 degrees past center.
10. Turn the ignition to off position.
11. If procedure was done correctly, ESC malfunction
lamp will flashfour times after engine starts.
12. Procedure must be completed within 90 seconds.
13. Repeat the condition to re-enable Hill Start Assist
(HSA).
HSA Activation Criteria
The following criteria must be met in order for HSA to
activate:
•Vehicle must be stopped.

WARNING! (Continued)
•HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
•Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. ESC cor-
rects for over-steering and under-steering the vehicle by
applying the brake of the appropriate wheel. Engine
power may also be reduced to help the vehicle maintain
the desired path.ESC reduces engine torque and applies brake pressure to
select individual wheels to mitigate vehicle under-steer
and vehicle over-steer. The system uses engine torque
reduction along with individual wheel brake pressure to
correct under-steer and over-steer conditions.
•Over-steer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Under-steer - when the vehicle is turning less than
appropriate for the steering wheel position.
ESC Off Indicator Light
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is off.
In some cases, when accelerating from stop on steep
grades, it may be beneficial to turn off ESC. Once the
grade ascent is complete, ESC can be turned on again.

WARNING!
•When inPartial Off mode, the TCS functionality
of ESC, (except for the limited slip feature de-
scribed in the TCS section), has been disabled and
the ESC Off Indicator Light will be illuminated.
When in Partial Off mode, the engine power
reduction feature of TCS is disabled, and the
enhanced vehicle stability offered by the ESC
system is reduced.
•Trailer Sway control (TSC) is disabled when the
ESC system is in the Partial Offmode. NOTE:
When driving with snow chains, or when start-
ing off in deep snow, sand, or gravel, it may be desirable
to allow more wheel spin when starting off in snow, mud,
sand, gravel, or when using tire chains. This can be
accomplished by momentarily pressing the ESC off”
button to enter partial mode “Partial Off” mode. Once the
situation requiring “Partial Off” mode is overcome, turn
ESC back on by momentarily pressing the “ESC Off”
button. This may be done while the vehicle is in motion.

loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
authorized tire dealer for radial tire repairs.
Spare Tire Matching Original Equipped Tire And
Wheel – If Equipped
Your vehicle may be equivalent with a spare tire and
wheel in look and function as the original equipment tire
and wheel found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rotation for your
5

Page 442 of 604

vehicle. If your vehicle has this option refer to an
authorized tire dealer for the recommended tire rotation
pattern.
If your vehicle is not equipped with an original equip-
ment tire and wheel as a spare, a non-matching tempo-
rary emergency use spare may be equipped with your
vehicle. Temporary use spares are engineered to be used
only with your vehicle. Your vehicle may be equipped
with one of the following types of non-matching tempo-
rary use spares; compact, full size, or limited-use. Do not
install more than one non-matching temporary use spare
tire/wheel on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact, full size or limited-use temporary spare
installed. Damage to the vehicle may result.
Compact Spare Tire – If Equipped
The compact spare is for temporary emergency use only.
You can identify if your vehicle is equipped with a
compact spare by looking at the spare tire description on
the Tire and Loading Information Placard located on the
driver ’s side door opening or on the sidewall of the tire.
Compact spare tire descriptions begin with the letter “T”
or “S” preceding the size designation. Example: T145/
80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life the original equip-
ment tire should be repaired (or replaced) and reinstalled
on your vehicle at the first opportunity.
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare tire.
Do not install more than one compact spare tire and
wheel on the vehicle at any given time
440 STARTING AND OPERATING
Page 443 of 604

WARNING!
Compact spares are for temporary emergency use
only. With these spares, do not drive more than
50 mph (80 km/h). Temporary use spares have limited
tread life. When the tread is worn to the tread wear
indicators, the temporary use spare tire needs to be
replaced. Be sure to follow the warnings, which
apply to your spare. Failure to do so could result in
spare tire failure and loss of vehicle control.
Full Size Spare – If Equipped
The full size spare is for temporary emergency use only.
This tire may look like the original equipped tire on the
front or rear axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the tread is worn
to the tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the same asyour original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.
Limited-Use Spare – If Equipped
The limited-use spare tire is for temporary emergency
use only. This tire is identified by a label located on the
limited-use spare wheel. This label contains the driving
limitations for this spare. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited-use spare
tire affects vehicle handling. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at the
first opportunity.

WARNING!
Limited-use spares are for emergency use only. In-
stallation of this limited-use spare tire affects vehicle
handling. With this tire, do not drive more than the
speed listed on the limit-use spare wheel. Keep
inflated to the cold tire inflation pressure listed on
your Tire and Loading Information Placard located
on the driver ’s side door opening. Replace (or repair)
the original equipment tire at the first opportunity
and reinstall it on your vehicle. Failure to do so could
result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping when you are stuck.Refer to “Freeing A Stuck Vehicle” in “What To Do In
Emergencies” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure some-
one. Do not spin your vehicle’s wheels faster than
30 mph (48 km/h) or for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.
Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
