{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.

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
on page 5-22.
4-34 Driving Your Vehicle
The grades are molded on the
sidewalls of most passenger car
tires. The Uniform Tire Quality
Grading (UTQG) system does
not apply to deep tread,
winter-type snow tires,
space-saver, or temporary use
spare tires, tires with nominal rim
diameters of 10 to 12 inches
(25 to 30 cm), or to some
limited-production tires.
While the tires available on
General Motors passenger cars
and light trucks may vary with
respect to these grades, they
must also conform to federal
safety requirements and
additional General Motors Tire
Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a
comparative rating based
on the wear rate of the tire when
tested under controlled
conditions on a speci ed
government test course.For example, a tire graded 150
would wear one and a half
(1.5) times as well on the
government course as a tire
graded 100. The relative
performance of tires depends
upon the actual conditions of
their use, however, and may
depart signi cantly from the norm
due to variations in driving habits,
service practices, and differences
in road characteristics and
climate.
Traction – AA, A, B, C
The traction grades, from highest
to lowest, are AA, A, B, and C.
Those grades represent the
tire’s ability to stop on wet
pavement as measured under
controlled conditions on speci ed
government test surfaces of
asphalt and concrete. A tire
marked C may have poor traction
performance.Temperature – A, B, C
The temperature grades
are A (the highest), B, and C,
representing the tire’s resistance
to the generation of heat and
its ability to dissipate heat
when tested under controlled
conditions on a speci ed indoor
laboratory test wheel. Sustained
high temperature can cause
the material of the tire to
degenerate and reduce tire life,
and excessive temperature
can lead to sudden tire failure.
The grade C corresponds to
a level of performance which
all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard
No. 109. Grades B and A
represent higher levels of
performance on the laboratory
test wheel than the minimum
required by law. It should
be noted that the temperature
grade for this tire is established
for a tire that is properly
in ated and not overloaded.
