The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the engine
and protects components. If the ignition key is
turned to the START position, and then released
when the engine begins cranking, the engine will
continue cranking for a few seconds or until the
vehicle starts. If the engine does not start and the
key is held in START, cranking will be stopped
after 15 seconds to prevent cranking motor
damage. To prevent gear damage, this system also
prevents cranking if the engine is already running.
Engine cranking can be stopped by turning the
ignition switch to the ACC/ACCESSORY or LOCK/
OFF position.
Notice: Cranking the engine for long periods of
time, by returning the key to the START position
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. 2. If the engine does not start after 5‐10 seconds,
especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Try pushing the accelerator pedal all the way to the
floor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait at
least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, repeat
these steps. This clears the extra gasoline from the
engine. 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.
Notice: The engine is designed to work with the
electronics in the vehicle. If you add electrical parts
or accessories, you could change the way the
engine operates. Before adding electrical
equipment, check with your dealer. If you do not,
the engine might not perform properly. Any
resulting damage would not be covered by the
vehicle warranty.

Lane Departure Warning (LDW)
The vehicle may have a Lane Departure Warning
(LDW) system. Read this entire section before using the
system.
{WARNING:
The Lane Departure Warning (LDW) system does
not steer the vehicle and is only an aid to help
you stay in your driving lane. The LDW system
may not:
.Provide you with enough time to avoid a lane
change collision.
.Be loud enough for you to hear the warning
beeps.
.Work properly under bad weather conditions
or if the windshield is not kept clean.
.Detect lane markings and will not detect road
edges.
.Warn you that your vehicle is crossing a lane
marking if the system does not detect the lane
marking.(Continued)
WARNING: (Continued)
LDW will indicate the system is working whenever
it detects either the left or right lane marking. So if
you depart on the side of the lane that LDW is not
detecting, LDW will not warn you.
If you do not carefully maintain your vehicle
position within the lane, vehicle damage, injury,
or death could occur. Even with LDW, always
keep your attention on the road and maintain
proper vehicle position within the lane. Always
keep the windshield clean and do not use LDW in
bad weather conditions.
When the vehicle crosses a detected lane marking, the
LDW symbol will flash and you will hear three beeps.
LDW will not warn you if the turn signal is on or if you
make a sharp maneuver. Before making a lane change,
check the vehicle's mirrors, glance over your shoulder
for vehicles and hazards, and start the turn signal
before changing lanes.

2 3:Headlamp High/Low-Beam Changer
N: Windshield Wipers
L: Windshield Washer
Flash-To-Pass Feature.
Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the
instrument panel
cluster flashes in the
direction of the turn or
lane change.
For vehicles with the side blind zone alert system, an
arrow in the outside mirror flashes when the turn signal
is used. See Side Blind Zone Alert (SBZA)
on
page 3‑39for more information.
Move the lever all the way up or down to signal a turn.
Raise or lower the lever until the arrow starts to flash to
signal a lane change. Hold it there until the lane change
is complete. If the lever is briefly pressed and released,
the turn signal will flash three times.
The lever returns to its starting position when it is
released.
If after signaling a turn or lane change the arrow flashes
rapidly or does not come on, a signal bulb may be
burned out.
Have the bulbs replaced. If the bulb is not burned out,
check the fuse. See Fuses and Circuit Breakers
on
page 6‑110.
4-5

Turn Signal On Chime
If the turn signal is left on, a warning chime sounds and
the Driver Information Center (DIC) will display TURN
SIGNAL ON after driving about a mile as a reminder to
turn it off. SeeDIC Warnings and Messages
on
page 4‑55.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high beam,
push the turn signal lever away from you. To change
from high beam to low beam, pull the turn signal lever
toward you.
While the high beams are
on, this light located on
the instrument panel
cluster will also be on.
Flash-to-Pass
This feature lets you use the high-beam headlamps to
signal the driver in front of you that you want to pass.
It works even if your headlamps are off.
Pull the turn signal lever toward you briefly to
flash-to-pass.
If the headlamps are off or on low beam, the high-beam
headlamps will turn on. They will stay on as long as you
hold the lever toward you and the high-beam indicator
on the instrument panel cluster will come on.
Windshield Wipers
The windshield wiper lever is located on the left side of
the steering column.
Turn the band with the wiper symbol on it to control the
windshield wipers.
8 (Mist): For a single wiping cycle, hold it on mist until
the wipers start, then release. The wipers stop after one
wipe. Several wipes, hold the band longer.
6(Delay): Use to set the delay time between wipe
cycles. The wiper speed can be set for a long or short
delay between wipes. The closer the band is set to the
top of the lever, the shorter the delay.
4-6

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers are turned on and have
completed eight wipe cycles within four minutes.
When the ignition is turned to LOCK/OFF, the
wiper-activated headlamps immediately turn off. The
wiper-activated headlamps also turn off if the windshield
wipers are turned off.
Headlamps on Reminder
If you leave the exterior lamp buttons for the headlamps
or parking lamps on, remove the key from the ignition
and open the driver's door, you will hear a continuous
warning chime. The chime will turn off when the lamps
are turned off.
Daytime Running Lamps (DRL)
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
Fully functional daytime running lamps are required on
all vehicles first sold in Canada.
A light sensor on top of the instrument panel monitors
the exterior light level for the operation of DRL, so be
sure it is not covered.The DRL system makes the low-beam headlamps turn
on at reduced brightness in daylight when the following
conditions are met:
.The ignition is on.
.The exterior lamp button for the headlamps is off.
.The automatic transmission is not in P (Park).
When the DRL are on, only the low-beam headlamps
will be on. The parking lamps, taillamps, sidemarker
and other lamps will not be on.
When it is dark enough outside, the low-beam
headlamps will come on. The other lamps that turn on
with the headlamps will also turn on. When it is bright
enough outside, the regular lamps will go off, and the
low-beam headlamps change to the reduced brightness
of DRL.
To turn off all exterior lighting at night when the
vehicle is parked, turn the exterior lamp control to
the off position. The exterior lamps will turn back on
automatically when the transmission is moved out of
P (Park). See Exterior Lamps
on page 4‑12for more
information.
The regular headlamp system should be turned on
when needed.

To change the current mode, select one of the following:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level): Air is divided between the instrument
panel outlets and the floor outlets. Slightly cooler air is
directed to the instrument panel outlets and warmer air
is directed to the floor outlets.
6(Floor): Air is directed to the floor outlets, with some
air directed to the windshield and side window outlets.
If recirculation is selected while in this mode, it stays on
for three minutes to reduce windshield fogging.
-(Floor/Defog): This clears the windows of fog or
moisture. Air is directed to the windshield and side
window outlets and to the floor outlets. The system
runs the air conditioning compressor unless the outside
temperature is near or below freezing.
0(Defrost): This mode clears the windshield of
fog or frost more quickly. Air is directed to the
windshield and side window outlets. The system runs
the air conditioning compressor unless the outside
temperature is near or below freezing.
#(Air Conditioning): Press to turn the air
conditioning system on or off. An indicator light below
the button comes on to show that this mode is on. Air
conditioning can be selected in any mode as long as
the fan knob is not in the off position.
On hot days during the vehicle's initial start-up, open
the windows to let hot inside air escape; then close
them. This helps to reduce the time it takes for the
vehicle to cool down. It also helps the system to operate
more efficiently.
For quicker cool down on hot days, do the following:
1. Select
H.
2. Select
h.
3. Select
#.
4. Select the coolest temperature.
5. Select the highest fan speed.
The air-conditioning system removes moisture from the
air, so a small amount of water might drip under the
vehicle while idling or after turning off the engine. This
is normal.
4-20

Automatic Operation
AUTO (Automatic Fan):When AUTO is selected on
the fan control, the system automatically adjusts the fan
speed. If the OnStar
®system is activated when this
position is selected, the fan speed will lower.
AUTO (Automatic Mode)
1. Turn the fan control to AUTO.
2. Turn the mode control to AUTO.
3. Adjust the temperature to a comfortable setting between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system starts at
reduced fan speeds to avoid blowing cold air into
the vehicle until warmer air is available. The
system will start out blowing air to the floor, but
may change modes automatically as the vehicle
warms up to maintain the chosen temperature
setting. The length of time needed to warm the
interior depends on the outside temperature.
4. Wait a few minutes for the system to automatically regulate. Then adjust the temperature as
necessary to find your comfort setting. Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see
“Sensors”later in
this section.
After the vehicle is started, the display shows the
interior temperature settings.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
shows readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between the readings.
AUTO (Automatic Air Conditioning): If AUTO is
selected on the fan or mode control, the system
automatically controls the air conditioning compressor.
The A/C compressor runs automatically even at cool
outside temperatures in order to dehumidify the air. The
A/C indicator light is lit when the system is operating
automatically. Press the A/C button on the fan control to
turn off the A/C. To clear windows better in defog or
defrost modes, the A/C compressor runs automatically
in damp cool conditions.
