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 rear (driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
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 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.
324 STARTING AND OPERATING

WARNING!(Continued)
water. Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to follow this
warning may result in injuries that are serious or
fatal to you, your passengers, and others around you.
Shallow Standing Water
Although your vehicle is capable of driving through
shallow standing water, consider the following Caution
and Warning before doing so.
CAUTION!
•Always check the depth of the standing water
before driving through it. Never drive through
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
(Continued)
CAUTION! (Continued)
•Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such
damage is not covered by the New Vehicle Limited
Warranty.
(Continued)
326 STARTING AND OPERATING

CAUTION!(Continued)
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
WARNING!
• Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
(Continued)
WARNING! (Continued)
•Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and leave you
stranded.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.

STARTING AND OPERATING 327

NOTE:
•Increased noise levels at the end of the steering wheel
travel are considered normal and do not indicate that
there is a problem with the power steering system.
• Upon initial start-up in cold weather, the power steer-
ing pump may make noise for a short amount of time.
This is due to the cold, thick fluid in the steering
system. This noise should be considered normal, and it
does not in any way damage the steering system.
WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.
FUEL SAVER TECHNOLOGY — IF EQUIPPED
This feature offers improved fuel economy by shutting
off four of the engine’s eight cylinders during light load
and cruise conditions. The system is automatic with no
driver inputs or additional driving skills required.
NOTE: This system may take some time to return to full
functionality after a battery disconnect.
328 STARTING AND OPERATING

CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic
brake systems. If either of the two hydraulic
systems loses normal capability, the remaining
system will still function. There will be some
loss of overall braking effectiveness. This may be evident
by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the “Brake Warning Light.” In the event power assist is lost for any reason (for
example, repeated brake applications with the engine
OFF) the brakes will still function. The effort required to
brake the vehicle will be much greater than that required
with the power system operating.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system automatically “pumps”
the brakes during severe braking conditions to prevent
wheel lock-up.
The Electronic Brake Force Distribution (EBD) prevents
the rear wheels from over-braking and provides greater
control of available braking forces applied to the rear
axle.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
332 STARTING AND OPERATING

WARNING!(Continued)
ABS cannot prevent collisions, including those re-
sulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning. The capa-
bilities of an ABS-equipped vehicle must never be
exploited in a reckless or dangerous manner that
could jeopardize the user’s safety or the safety of
others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
driven wheel. If wheel spin is detected, brake pressure is
applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability.
A feature of the TCS system functions similar 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 TCS and ESC are in
the “Partial Off” or “Full Off” modes. Refer to “Electronic
Stability Control (ESC)” in this section for more informa-
tion.
Brake Assist System (BAS)
This system complements the ABS by optimizing the
vehicle braking capability during emergency braking
maneuvers. This system detects an emergency braking
situation by sensing the rate and amount of brake appli-
cation and then applies optimum pressure to the brakes.
This can help reduce braking distances.
Applying the brakes very quickly results in the best BAS
assistance. To receive the benefits of this system, you
must apply continuous brake pedal pressure during the
stopping sequence. Do not reduce brake pedal pressure
336 STARTING AND OPERATING

WARNING!
There may be situations on minor hills (i.e., less than
8%), with a loaded vehicle, or while pulling a trailer,
when the system will not activate and slight rolling
may occur. This could cause a collision with another
vehicle or object. Always remember the driver is
responsible for braking the vehicle.
Disabling/Enabling HSA
If you wish to turn on or off the HSA system, it can be
done using the Customer Programmable Features in the
Electronic Vehicle Information Center (EVIC). Refer to
“Electronic Vehicle Information Center (EVIC)” in “Un-
derstanding Your Instrument Panel” for further informa-
tion.For vehicles not equipped with the EVIC, perform the
following steps:
NOTE:
You must complete Steps 1 through 8 within 90
seconds.
1. Center the steering wheel (front wheels pointing straight forward).
2. Shift the transmission into NEUTRAL.
3. Apply the parking brake.
4. Start the engine.
5. Release the clutch pedal (if equipped).
6. Rotate the steering wheel one-half turn to the left.
7.
Press the “ESC Off” switch (located in the lower switch
bank below the climate controls) four times within 20
seconds. The “ESC Activation/Malfunction Indicator
Light” should turn on and turn off two times.
