Daytime Running Lamps (DRL)
DRL can make it easier for others to see the
front of your vehicle during the day. DRL are
required on all vehicles first sold in Canada.
The DRL system makes the dedicated lamps
come on when the following conditions
are met:
.The ignition is on.
.The exterior lamp control is in the AUTO.
.The light sensor determines it is daytime.When DRL are on, only the front lamps will
be on. The parking lamps, taillamps,
instrument panel lights, or other exterior
lamps will not be on when the DRL are
being used.
When it is dark enough outside, the front
lamps dim to parking lamps and the normal
low-beam headlamps turn on.
The regular headlamp system should be
turned on when needed.
To turn off the DRL, turn the exterior lamp
control to
O. The DRL will stay off until the
control is toggled again.
Automatic Headlamp System
When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps and parking lamps come on
automatically.
There is a light sensor on top of the
instrument panel. Do not cover the sensor,
otherwise the headlamps will come on when
they are not needed.
The system may also turn on the headlamps
and parking lamps when driving through a
parking garage or tunnel.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system changes to the DRL. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright
position. See Instrument Panel Illumination
Control 0109.

174 Climate Controls
Caution
Using a razor blade or sharp object to
clear the inside rear window can damage
the rear window defogger. Repairs would
not be covered by the vehicle warranty.
Do not clear the inside rear window with
sharp objects.
Remote Start Climate Control Operation :
If equipped with remote start, the climate
control system may run when the vehicle is
started remotely. If equipped with heated or
ventilated seats or a heated steering wheel,
these features may come on during a
remote start. See Remote Vehicle Start 012,
Heated and Ventilated Front Seats 044, and

direction of the airflow or shut the outlet.
Operation Tips
.Clear away any ice, snow, or leaves from
the air inlets at the base of the
windshield that may block the flow of air
into the vehicle.
.Clear snow off the hood to improve
visibility and help decrease moisture
drawn into the vehicle.
.Use of non-GM approved hood deflectors
may adversely affect the performance of
the system.
.Keep the area around the base of the

under the seats clear of objects to help
circulate the air inside of the vehicle more
effectively.
Maintenance
Passenger Compartment Air Filter
The passenger compartment air filter
reduces dust, pollen, and other airborne
irritants from outside air that are pulled into
the vehicle. Reductions in airflow, which
may occur more often in dusty areas,
indicate that the filter may need to be
replaced. See Maintenance Schedule 0293.
Caution
Driving without a passenger compartment
air filter in place can cause water and
small particles, like paper and leaves, to
be pulled into your climate control
(Continued)
Caution (Continued)
system which may cause damage to it.
Make sure you always replace the old
filter with a new one.
The passenger compartment air filter is
located under the hood between the battery
and windshield. See Underhood
Compartment Overview 0234.
To check or replace the air filter:
1. Release the four clips for the left and right outer covers.

188 Driving and Operating
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and the road
creates less traction or grip, so drive
carefully. Wet ice can occur at about 0 °C
(32 °F) when freezing rain begins to fall.
Avoid driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating too quickly
causes the wheels to spin and makes the
surface under the tires slick.
.Turn on Traction Control. SeeTraction
Control/Electronic Stability Control 0206.
.The Antilock Brake System (ABS) improves
vehicle stability during hard stops, but
the brakes should be applied sooner than
when on dry pavement. See Antilock
Brake System (ABS) 0204.
.Allow greater following distance and
watch for slippery spots. Icy patches can
occur on otherwise clear roads in shaded
areas. The surface of a curve or an
overpass can remain icy when the
surrounding roads are clear. Avoid sudden
steering maneuvers and braking while
on ice.
.Turn off cruise control.
.Turn on Weather Mode. See Driver Mode
Control 0208.
Blizzard Conditions
Stop the vehicle in a safe place and signal
for help. Stay with the vehicle unless there
is help nearby. If possible, use Roadside
Assistance. See Roadside Assistance Program
0 311. To get help and keep everyone in the
vehicle safe:
.Turn on the hazard warning flashers.
.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 snow:
.Clear snow from the base of the
vehicle, especially any blocking the
exhaust pipe.
(Continued)
Warning (Continued)
.Open a window about 5 cm (2 in) on
the vehicle side 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
circulate the air inside the vehicle and
set the fan speed to the highest
setting. See“Climate Control Systems.”
For more information about CO, see
Engine Exhaust 0197.
To save fuel, run the engine for short
periods to warm the vehicle and then shut
the engine off and partially close the
window. Moving about to keep warm also
helps.
If it takes time for help to arrive, when
running 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.

when starting or turning off the engine.1. Press the brake pedal, then press ENGINE START/STOP on the instrument panel.
If there is no remote key in the vehicle
or if there is something causing
interference with it, the Driver
Information Center (DIC) will display a
message.
2. When the engine begins cranking, let go of the button and the engine cranks
automatically until it starts.
If the battery in the remote key is weak,
the DIC will display a message. The
vehicle can still be driven.
See “Starting the Vehicle with a Low

Keyless Entry (RKE) System Operation 07
. If the remote key battery is dead,
insert it into the cupholder remote key
pocket to enable engine starting.
3. Do not race the engine immediately after starting it. Operate the engine and
transmission gently until the oil warms
up and lubricates all moving parts. 4. If the engine does not start and no DIC
message is displayed, wait 15 seconds
before trying again to let the cranking
motor cool down.
If the engine does not start after five to
10 seconds, especially in very cold
weather (below −18 °C or 0 °F), it could
be flooded with too much gasoline. Try
pushing the accelerator pedal all the way
to the floor while cranking for up to
15 seconds maximum. Wait at least
15 seconds between each try, to allow
the cranking motor to cool down. When
the engine starts, let go of the
accelerator. If the vehicle starts briefly
but then stops again, repeat these steps.
This clears the extra gasoline from the
engine.
Caution
Cranking the engine for long periods of
time, by pressing ENGINE START/STOP
immediately after cranking has ended,
can overheat and damage the cranking
motor, and drain the battery. Wait at
least 15 seconds between each try, to let
the cranking motor cool down.
Stopping the Engine
Shift to P (Park) and press and hold ENGINE
START/STOP on the instrument panel, until
the engine shuts off. If the transmission is
not in P (Park), the engine shuts off and the
vehicle goes into the accessory mode. The
