438 STARTING AND OPERATING

NOTE:The torque converter clutch will not engage until
the transmission fluid and engine coolant are warm
[usually after 1 to 3 miles (2 to 5 km) of driving]. Because
the engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmission
is not shifting into Overdrive when cold. This is normal.
Using the AutoStick® shift control, when the transmis-
sion is sufficiently warm, will demonstrate that the
transmission is able to shift into and out of Overdrive.
DRIVING ON SLIPPERY SURFACES
Acceleration
Rapid acceleration on snow covered, wet, or other slip-
pery surfaces may cause the driving wheels to pull
erratically to the right or left. This phenomenon occurs
when there is a difference in the surface traction under
the front (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the
front wheels. You could lose control of the vehicle
and possibly have a collision. 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 hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should
be observed:
1. Slow down during rainstorms or when the roads are slushy.

STARTING AND OPERATING 457

Anti-Lock Brake Warning Light
The “Anti-Lock Brake Warning Light” moni-
tors the anti-lock brake system. 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 “Anti-Lock Brake Warning 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 “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the “Anti-Lock Brake Warning 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 “Anti-Lock
Brake Warning Light” remain on, the ABS and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
Consult with your authorized dealer service center as
soon as possible.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Traction Control
System (TCS), Brake Assist System (BAS) and Electronic
Stability Control (ESC), Trailer Sway Control (TSC), and
Hill Start Assist (HSA). These systems complement the
Anti-Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneu-
vers.
466 STARTING AND OPERATING

Traction Control System (TCS)
The Traction Control System (TCS) monitors the amount
of wheel spin of each of the driven wheels. If wheel spin
is detected, brake pressure is applied to the slipping
wheel(s) and engine power is reduced, to provide en-
hanced acceleration and stability. A feature of the TCS
functions similarly to a limited-slip differential, and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if
the ESC is in the “Partial Off” mode.
The “ESC Activation/Malfunction Indicator Light” (in
the instrument cluster) will start to flash as soon as the
tires lose traction and the wheels begin to spin. This
indicates that the TCS is active. If the indicator light
flashes during acceleration, ease up on the accelerator
and apply as little throttle as possible. Be sure to adaptyour speed and driving to the prevailing road conditions,
and do not switch off the ESC or TCS.
WARNING!
•
The TCS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.
• The TCS cannot prevent collisions, including those
resulting from excessive speed in turns, or hydro-
planing.
• The capabilities of a TCS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.

STARTING AND OPERATING 467

Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize
the vehicle’s braking capability during emergency brak-
ing maneuvers. The system detects an emergency brak-
ing situation by sensing the rate and amount of brake
application, and then applies optimum pressure to the
brakes. This can help reduce braking distances. The BAS
complements the ABS. Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of
the system, you must apply continuous braking pressure
during the stopping sequence. Do not reduce brake pedal
pressure unless braking is no longer desired. Once the
brake pedal is released, the BAS is deactivated.
WARNING!
•The BAS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road conditions.
• The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
• The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.
Electronic Stability Control (ESC)
The Electronic Stability Control (ESC) enhances direc-
tional control and stability of the vehicle under various
driving conditions. ESC corrects for over/under steering
of the vehicle by applying the brake of the appropriate
468 STARTING AND OPERATING

wheel to assist in counteracting the over/under steer
condition. Engine power may also be reduced to help the
vehicle maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.WARNING!
The Electronic Stability Control System (ESC) cannot
prevent the natural laws of physics from acting on
the vehicle, nor can it increase the traction afforded
by prevailing road conditions. ESC cannot prevent
all accidents, including those resulting from exces-
sive speed in turns, driving on very slippery surfaces,
or hydroplaning. ESC also cannot prevent accidents
resulting from loss of vehicle control due to inappro-
priate driver input for the conditions. Only a safe,
attentive, and skillful driver can prevent accidents.
The capabilities of an ESC equipped vehicle must
never be exploited in a reckless or dangerous manner
which could jeopardize the user ’s safety or the safety
of others.

STARTING AND OPERATING 469

WARNING!
•When in Partial 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 sys-
tem is reduced.
• Trailer Sway Control (TSC) is disabled when the
ESC system is in the Partial Offmode.
NOTE: To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC Off” switch. Once the situa-
tion requiring ESC to be switched to the “Partial Off”
mode is overcome, turn ESC back on by momentarily pressing the “ESC Off” switch. This may be done while
the vehicle is in motion.ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should turn off with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.

STARTING AND OPERATING 471

The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
NOTE:
•The “ESC Activation/Malfunction Indicator Light”
and the “ESC OFF Indicator Light” come on momen-
tarily each time the ignition switch is turned ON.
• Each time the ignition is turned ON, the ESC system
will be ON even if it was turned off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. No driver action is re-
quired. Note that TSC cannot stop all trailers from
swaying. Always use caution when towing a trailer and
follow the trailer tongue weight recommendations. Refer
