StabiliTrak®System
Your vehicle has the StabiliTrak®system which
combines antilock brake, traction and stability
control systems and helps the driver maintain
directional control of the vehicle in most driving
conditions.
When you rst start your vehicle and begin to
drive away, the system performs several
diagnostic checks to ensure there are no
problems. You may hear or feel the system
working. This is normal and does not mean
there is a problem with your vehicle. The system
should initialize before the vehicle reaches
20 mph (32 km/h). In some cases, it may take
approximately two miles of driving before the
system initializes.
If the system fails to turn on or activate, the
StabiliTrak
®light along with one of the following
messages will be displayed on the Driver
Information Center (DIC): TRACTION CONTROL
OFF, SERVICE TRACTION CONTROL,
SERVICE STABILITRAK. If you see these
conditions, turn the vehicle off, wait 15 seconds,
and then turn it back on again to reset the system.If any of these messages still appear on the Driver
Information Center (DIC), your vehicle should
be taken in for service. For more information on
the DIC messages, seeDriver Information
Center (DIC) on page 232.
The StabiliTrak
®light
will ash on the
instrument panel cluster
when the system is
both on and activated.
You may also feel or hear the system working;
this is normal.
The traction control
disable button is located
on the instrument
panel below the climate
controls.
The traction control part of StabiliTrak
®can be
turned off by pressing and releasing the traction
control disable button.

Tow/Haul Mode
Tow/Haul is a feature that assists when pulling a
heavy trailer or a large or heavy load. The purpose
of the Tow/Haul mode is to:
Reduce the frequency and improve the
predictability of transmission shifts when pulling
a heavy trailer or a large or heavy load.
Provide the same solid shift feel when pulling a
heavy trailer or a large or heavy load as when
the vehicle is unloaded.
Improve control of vehicle speed while requiring
less throttle pedal activity when pulling a heavy
trailer or a large or heavy load.
Increase the charging system voltage to assist
in recharging a battery installed in a trailer.
Press this button on
the console to
enable/disable the
tow/haul mode.A light on the instrument
panel will come on to
indicate that tow/haul
mode has been
selected.
Tow/Haul may be turned off by pressing the
button again, at which time the indicator light on
the instrument panel will turn off. The vehicle
will automatically turn off Tow/Haul every time
it is started.
Tow/Haul is designed to be most effective when
the vehicle and trailer combined weight is at
least 75 percent of the vehicle’s Gross Combined
Weight Rating (GCWR). See Weight of the Trailer
later in this section. Tow/Haul is most useful
under the following driving conditions:
When pulling a heavy trailer or a large or
heavy load through rolling terrain.
When pulling a heavy trailer or a large or
heavy load in stop and go traffic.
When pulling a heavy trailer or a large or heavy
load in busy parking lots where improved low
speed control of the vehicle is desired.

Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a
good deal longer, you’ll need to go much farther
beyond the passed vehicle before you can
return to your lane.
Backing Up
Hold the bottom of the steering wheel with
one hand. Then, to move the trailer to the left,
just 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
Notice:Making very sharp turns while
trailering could cause the trailer to come in
contact with the vehicle. Your vehicle could
be damaged. Avoid making very sharp turns
while trailering.When you’re turning with a trailer, make wider
turns than normal. Do this so your trailer
won’t 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
When you tow a trailer, your vehicle may need a
different turn signal asher and/or extra wiring.
Check with your dealer/retailer. The arrows
on your instrument panel will ash whenever you
signal a turn or lane change. Properly hooked
up, the trailer lamps will also ash, telling other
drivers you’re about to turn, change lanes or stop.
When towing a trailer, the arrows on your
instrument panel will ash for turns even if the
bulbs on the trailer are burned out. Thus, you may
think drivers behind you are seeing your signal
when they are not. It’s important to check
occasionally to be sure the trailer bulbs are
still working.

own weight. Check to make sure the hood is
closed. If the hood does not fully latch, gently push
the hood down at the front and center of the
hood until it is completely latched.

Radiator Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is properly
and tightly secured.
SeeEngine Compartment Overview on page 396
for more information on location.
Engine Overheating
There is an engine coolant temperature gage on
your vehicle’s instrument panel. SeeEngine
Coolant Temperature Gage on page 225.
Your vehicle may also have an ENGINE
OVERHEATED IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE message
displayed in the Driver Information Center (DIC).
SeeDIC Warnings and Messages on page 244.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Turn it
off and get everyone away from the
vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
CAUTION: (Continued)
