4-53

Notice:If the wheel(s) of one axle are allowed to
spin excessively while the ESC/TCS, ABS and
Brake warning lights and the SERVICE ESC and/or
SERVICE TRACTION messages are displayed, the
differential could be damaged. The repairs would
not be covered by the vehicle warranty. Reduce
engine power and do not spin the wheel(s)
excessively while these lights and this message
are displayed.
Notice: When traction control is turned off,
or Competitive Driving Mode is active, it is
possible to lose traction. If you attempt to shift with
the drive wheels spinning with a loss of traction,
it is possible to cause damage to the transmission.
Do not attempt to shift when the drive wheels do
not have traction. Damage caused by misuse of the
vehicle is not covered. See the warranty book for
additional information.
The traction control system may activate on dry or
rough roads or under conditions such as heavy
acceleration while turning or abrupt upshifts/downshifts
of the transmission. When this happens, a reduction
in acceleration may be noticed or a noise or vibration
may be heard. This is normal.
If the vehicle is in cruise control while the system
activates, the ESC/TCS light flashes and the cruise
control automatically disengages. The cruise control
can be re-engaged when road conditions allow. See
Cruise Control on page 4‑8. Adding non‐dealer/non‐retailer accessories can affect
the vehicle's performance. See
Accessories and
Modifications
on page 6‑3for more information.
Enhanced Traction System (ETS)
The vehicle may have an Enhanced Traction System
(ETS) that limits wheel spin. This is especially useful in
slippery road conditions. The system operates only if it
senses that one or both of the front wheels are spinning
or beginning to lose traction. When this happens, the
system reduces engine power and may also upshift the
transmission to limit wheel spin.
If the vehicle has ETS, there is not an ESC/TCS button
on the instrument panel. To turn the system off, shift to
L (Low) or R (Reverse). There is more information about
how to turn the system off later in this section.
The ETS indicator/warning light flashes and LOW
TRACTION appears on the Driver Information Center
(DIC) when the traction control system is actively
limiting wheel spin. The system may be heard or felt
while it is working, but this is normal. Slippery road
conditions may exist if this message is displayed, so
adjust your driving accordingly.
If the vehicle is in cruise control when the ETS begins
to limit wheel spin, the cruise control will automatically
disengage. The cruise control can be re-engaged when
road conditions allow. See Cruise Control on page 4‑8.
5-11

transmission is shifted to L (Low) or R (Reverse) to turn
the system off, the indicator/warning light and
TRACTION OFF will come on in L (Low). But the
system will not turn off right away. It will wait until there
is no longer a current need to limit wheel spin. SeeDIC
Warnings and Messages
on page 4‑48for more
information on the messages associated with this light.
The system can be turned back on at any time by
shifting to D (Automatic Overdive) or I (Intermediate).
The ETS indicator/warning light should go off.
Adding non‐dealer/non‐retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications
on page 6‑3for more information.
Limited-Slip Differential
Vehicles with a limited-slip differential can give more
traction on snow, mud, ice, sand or gravel. It works like
a standard axle most of the time, but when traction is
low, this feature allows the drive wheel with the most
traction to move the vehicle. The limited slip design has
minimal impact to the steering feel, but boosts the
traction performance under all conditions.
Steering
Electric Power Steering
If the engine stalls while driving, the power steering
assist system will continue to operate until you are
able to stop the vehicle. If power steering assist is lost
because the electric power steering system is not
functioning, the vehicle can be steered but it will take
more effort.
If you turn the steering wheel in either direction several
times until it stops, or hold the steering wheel in the
stopped position for an extended amount of time, you
may notice a reduced amount of power steering assist.
The normal amount of power steering assist should
return shortly after a few normal steering movements.
The electric power steering system does not require
regular maintenance. If you suspect steering system
problems and/or the POWER STEERING message
comes on, contact your dealer/retailer for service
repairs. See DIC Warnings and Messages
on
page 4‑48.

Blizzard Conditions
Being stuck in snow can be in a serious situation. Stay
with the vehicle unless there is help nearby. If possible,
use theRoadside Assistance Program
on page 8‑6.
To get help and keep everyone in the vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
.Check again from time to time to be sure
snow does not collect there.
(Continued)
WARNING: (Continued)
.Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting. See
Climate Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 3‑39.
Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill you.
You cannot see it or smell it, so you might not
know it is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking the exhaust.
Run the engine for short periods only as needed to
keep warm, but be careful.

Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, move that hand to
the left. To move the trailer to the right, move your hand
to the right. Always back up slowly and, if possible,
have someone guide you.
Making Turns
When turning with a trailer, make wider turns than
normal. Do this so the trailer will not strike soft
shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
The arrows on the instrument panel flash whenever
signaling a turn or lane change. Properly hooked up,
the trailer lamps also flash, telling other drivers the
vehicle is turning, changing lanes or stopping.
When towing a trailer, the arrows on the instrument
panel flash for turns even if the bulbs on the trailer are
burned out. For this reason you may think other drivers
are seeing the signal when they are not. It is important
to check occasionally to be sure the trailer bulbs are still
working.
Driving on Grades
Notice:Do not tow on steep continuous grades
exceeding 6 miles (9.6 km). Extended, higher than
normal engine and transmission temperatures may
result and damage the vehicle. Frequent stops are
very important to allow the engine and transmission
to cool.
When towing under severe conditions such as hot
ambient temperatures or steep grades, the vehicle may
experience more transmission shifting. A COOLING
MODE ON message may also appear in the DIC. This
alerts the driver that the shifting mode is in progress
and is aiding engine cooling. See DIC Warnings and
Messages
on page 4‑48DIC Warnings and Messages
for more information.
Reduce speed and shift to a lower gear beforestarting
down a long or steep downgrade. If the transmission is
not shifted down, the brakes might have to be used so
much that they would get hot and no longer work well.
Pay attention to the engine coolant gauge. If the
indicator is in the red area, turn off the air conditioning
to reduce engine load. See Engine Overheating
on
page 6‑34.
