2. Find the vehicle’s current
location and variance zone
number on the map.
Zones 1 through 15 are
available.
3. Press and hold the set/reset
button to scroll through and
select the appropriate
variance zone.
4. Press the trip/fuel button until the
vehicle heading, for example,
N for North, is displayed in
the DIC.5. If calibration is necessary,
calibrate the compass. See
“Compass Calibration Procedure”
following.
Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an open
parking lot, where driving the
vehicle in circles is not a danger. It
is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should be
calibrated.
If the DIC display does not show a
heading, for example, N for
North, or the heading does not
change after making turns, there
may be a strong magnetic eld
interfering with the compass. Such
interference may be caused by
a magnetic CB or cell phoneantenna mount, a magnetic
emergency light, magnetic note pad
holder, or any other magnetic
item. Turn off the vehicle, move the
magnetic item, then turn on the
vehicle and calibrate the compass.
To calibrate the compass, use
the following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass is set
to the variance zone in which the
vehicle is located. See
“Compass Variance (Zone)
Procedure” earlier in this section.
Do not operate any switches
such as window, sunroof, climate
controls, seats, etc. during the
calibration procedure.
2. Press the vehicle information
button until PRESS

Before Leaving on a
Long Trip
To prepare your vehicle for a long
trip, consider having it serviced
by your dealer/retailer before
departing.
Things to check on your own
include:
Windshield Washer Fluid:
Reservoir full? Windows
clean — inside and outside?
Wiper Blades:In good shape?
Fuel, Engine Oil, Other Fluids:All
levels checked?
Lamps:Do they all work and are
lenses clean?
Tires:Are treads good? Are tires
in ated to recommended
pressure?
Weather and Maps:Safe to
travel? Have up-to-date maps?
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving. If
you become tired or sleepy, nd a
safe place to park your vehicle
and rest.
Other driving tips include:
Keep the vehicle well ventilated.
Keep interior temperature cool.
Keep your eyes moving — scan
the road ahead and to the sides.
Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on at or rolling terrain. Tips for
driving in these conditions include:
Keep the vehicle serviced
and in good shape.
Check all uid levels and brakes,
tires, cooling system, and
transmission.
Going down steep or long hills,
shift to a lower gear.
{CAUTION
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.

Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 7-5.
To get help and keep everyone
in the vehicle safe:
Turn on theHazard Warning
Flashers on page 3-5.
Tie a red cloth to an outside
mirror.
{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.
(Continued)
CAUTION (Continued)
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.
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.
(Continued)
CAUTION (Continued)
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-26.
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.

Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If so, be
sure to seal the holes when the
hitch is removed. If they are not
sealed, deadly carbon
monoxide (CO) from the engine’s
exhaust can get into the vehicle.
SeeEngine Exhaust on
page 2-26. Sealing the holes will
also prevent dirt and water from
entering the vehicle.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the
safety chains under the tongue of
the trailer to help prevent the tongue
from contacting the road if it
becomes separated from the hitch.
Instructions about safety chains
may be provided by the hitch
manufacturer or by the trailermanufacturer. Follow the
manufacturer’s recommendation
for attaching safety chains and do
not attach them to the bumper.
Always leave just enough slack so
the rig can turn. Never allow safety
chains to drag on the ground.
Trailer Brakes
A loaded trailer that weighs more
than 1,000 lbs (900 kg) needs
to have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted
and maintained properly. Because
the vehicle has StabiliTrak
®,do
not try to tap into the vehicle’s
hydraulic brake system. If you do,
both brake systems will not
work well, or at all.
Driving with a Trailer
{CAUTION
When towing a trailer, exhaust
gases may collect at the rear of
the vehicle and enter if the liftgate,
trunk/hatch, or rear-most window
is open.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing
a trailer:
Have the exhaust system
inspected for leaks and make
necessary repairs before
starting a trip.
Never drive with the liftgate,
trunk/hatch, or rear-most
window open.
Fully open the air outlets on or
under the instrument panel.
