✍NOTES
3-128 Instrument Panel
The system may be heard or felt
while it is working. This is normal and
does not mean there is a problem
with the vehicle. The system should
initialize before the vehicle reaches
20 mph (32 km/h). In some cases, it
may take approximately two miles
(3.2 km) 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 these
conditions are observed, 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), the vehicle should
be taken in for service. For more
information on the DIC messages,
seeDriver Information Center (DIC)
on page 3-44.The StabiliTrak light will ash on the
instrument panel cluster when the
system is both on and activated.
The system may be heard or
felt while it is 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.Traction control can be turned
on by pressing and releasing the
traction control disable button if not
automatically shut off for any other
reason.
When the traction control system is
turned off, the StabiliTrak light and
the appropriate traction control off
message will be displayed on the
DIC to warn the driver. The vehicle
will still have brake-traction control
when traction control is off, but will
not be able to use the engine speed
management system. See “Traction
Control Operation” next for more
information.
When the traction control system
has been turned off, system noises
may be heard and felt as a result
of the brake-traction control working.
It is recommended to leave
the system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice or
snow, and you want to “rock”
the vehicle to attempt to free it.

{CAUTION
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.
Open a window about
two inches (5 cm) on the side
of the vehicle that is away
from the wind to bring in
fresh air.
(Continued)
CAUTION (Continued)
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, seeEngine Exhaust on
page 2-30.
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.
To save fuel, run the engine for
only short periods as needed
to warm the vehicle and then shut
the engine off and close the window
most of the way to save heat.
Repeat this until help arrives but
only when you feel really
uncomfortable from the cold. Moving
about to keep warm also helps.
If it takes some time for help
to arrive, now and then when you
run the engine, push the accelerator
pedal slightly so the engine runs
faster than the idle speed. This
keeps the battery charged to restart
the vehicle and to signal for help
with the headlamps. Do this as little
as possible to save fuel.
Driving Your Vehicle 4-15
Passing
More passing distance is needed
when towing a trailer. Because the
rig is longer, it is necessary to go
much farther beyond the passed
vehicle before returning to the lane.
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
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.When turning with a trailer, make
wider turns than normal. Do this so
the 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
The arrows on the instrument panel
ash whenever signaling a turn or
lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.
When towing a trailer, the arrows on
the instrument panel ash 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
Because of the added load of the
trailer, the vehicle’s engine may
overheat on hot days, when going up
a long or steep grade with a trailer. If
the engine coolant temperature gage
indicates overheating, turn off the air
conditioning to reduce engine load,
pull off the road and stop in a safe
spot. Let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off.
Reduce speed and shift to a lower
gearbeforestarting 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.
On a long uphill grade, shift down
and reduce the vehicle speed
to around 55 mph (88 km/h) to
reduce the possibility of the engine
and the transmission overheating.
Driving Your Vehicle 4-31
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 located on the
console to turn on and turn off the
Tow/Haul mode.
The Tow/Haul 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 earlier 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.
Operating the vehicle in Tow/Haul
when lightly loaded or with no
trailer at all will not cause damage.
However, there is no bene t to the
selection of Tow/Haul when the
vehicle is unloaded. Such a selection
when unloaded may result in
unpleasant engine and transmission
driving characteristics and reduced
fuel economy. Tow/Haul is
recommended only when pulling a
heavy trailer or a large or heavy load.

Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle’s frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer/retailer.
The seven-wire harness contains
the following trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.They should be connected by your
dealer/retailer or a quali ed
service center.
If the back-up lamp circuit is not
functional, contact your
dealer/retailer.
If a remote (non-vehicle) battery is
being charged, press the Tow/Haul
mode switch located on the center
console near the climate controls.
This will boost the vehicle system
voltage and properly charge the
battery. If the trailer is too light
for Tow/Haul mode, turn on the
headlamps (Non-HID only) as a
second way to boost the vehicle
system and charge the battery.
Electric Trailer Brake Control
Wiring Provisions
These wiring provisions for an
electric trailer brake controller
are included with the vehicle as
part of the trailer wiring package.The instrument panel contains blunt
cut wires behind the steering column
for the electric trailer brake controller.
The harness contains the following
wires:
Red/Black: Power Supply
White: Brake Switch Signal
Gray: Illumination
Dark Blue: Trailer Brake Signal
Black: Ground
The electric trailer brake controller
should be installed by your dealer/
retailer or a quali ed service center.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating

Checking Things
Under the Hood
{CAUTION
An electric fan under the hood
can start up and injure you even
when the engine is not running.
Keep hands, clothing, and tools
away from any underhood
electric fan.
{CAUTION
Things that burn can get on hot
engine parts and start a re.
These include liquids like fuel, oil,
coolant, brake uid, windshield
washer and other uids, and
plastic or rubber. You or others
could be burned. Be careful not to
drop or spill things that will burn
onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the hood release handle with
this symbol on it. It is located
under the instrument panel
on the driver’s side of the vehicle.
2. At the front of the vehicle, pull up
on the center of the hood, and
push the secondary hood release
to the right.3. After you have partially lifted the
hood, gas struts will automatically
take over to lift and hold the
hood in the fully open position.
Before closing the hood, be sure all
ller caps are on properly.
Pull the hood down to close. Lower
the hood until the lifting pressure
of the strut is reduced. Then allow
the hood to fall and latch into place
under its 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.
