When Should an Airbag Inate?
The driver’s and right front passenger’s frontal airbags
are designed to inate in moderate to severe frontal
or near-frontal crashes. But they are designed to inate
only if the impact exceeds a predetermined deployment
threshold. Deployment thresholds take into account
a variety of desired deployment and non-deployment
events and are used to predict how severe a crash
is likely to be in time for the airbags to inate and help
restrain the occupants. Whether your frontal airbags
will or should deploy is not based on how fast your
vehicle is traveling. It depends largely on what you hit,
the direction of the impact and how quickly your
vehicle slows down.
In addition, your vehicle has “dual stage” frontal airbags,
which adjust the restraint according to crash severity.
For moderate frontal impacts, these airbags inate at a
level less than full deployment. Your vehicle is
equipped with electronic frontal sensors, which help the
sensing system distinguish between a moderate
frontal impact and a more severe frontal impact.For more severe frontal impacts, full deployment occurs.
If the front of your vehicle goes straight into a wall
that does not move or deform, the threshold level for
the reduced deployment is about 12 to 18 mph
(19 to 29 km/h), and the threshold level for a full
deployment is about 18 to 25 mph (29 to 40.2 km/h).
(The threshold level can vary, however, with specic
vehicle design, so that it can be somewhat above
or below this range.)
Airbags may inate at different crash speeds. For
example:
If the vehicle hits a stationary object, the airbag
could inate at a different crash speed than if
the object were moving.
If the object deforms, the airbag could inate at a
different crash speed than if the object does not
deform.
If the vehicle hits a narrow object (like a pole) the
airbag could inate at a different crash speed
than if the vehicle hits a wide object (like a wall).
If the vehicle goes into an object at an angle the
airbag could inate at a different crash speed
than if the vehicle goes straight into the object.

The passenger sensing system will turn off the right
front passenger’s frontal airbag and side impact airbag
(if equipped) under certain conditions. The driver’s
airbag or airbags are not part of the passenger sensing
system.
The passenger sensing system works with sensors that
are part of the right front passenger’s seat and safety
belt. The sensors are designed to detect the presence of
a properly-seated occupant and determine if the
passenger’s airbag or airbags should be enabled (may
inate) or not.
Accident statistics show that children are safer if they
are restrained in the rear rather than the front seat.
General Motors recommends that child restraints
be secured in a rear seat, including an infant riding in a
rear-facing infant seat, a child riding in a forward-facing
child seat and an older child riding in a booster seat. Passenger Airbag Status Indicator – United States

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front or
sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, front end or side sheet
metal or height, they may keep the airbag system
from working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2
Q:Because I have a disability, I have to get my
vehicle modied. How can I nd out whether
this will affect my airbag system?
A:Changing or moving any parts of the front seats,
safety belts, the airbag sensing and diagnostic
module (located under the driver’s seat), or
the instrument panel can affect the operation of the
airbag system. If you have questions, call
Customer Assistance. The phone numbers and
addresses for Customer Assistance are in Step Two
of the Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure on
page 7-2.

Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35°F (2°C) or colder. You may notice
that the transaxle will shift at a higher vehicle speed until
the engine is warmed up. This is a normal condition
designed to provide heat to the passenger compartment
and defrost the windows more quickly. SeeClimate
Control System on page 3-25for more information.
THIRD (3):This position is also used for normal driving,
but it offers more power and lower fuel economy than
AUTOMATIC OVERDRIVE (D).
Here are some times you might choose THIRD (3)
instead of AUTOMATIC OVERDRIVE (D):
When driving on hilly, winding roads
When towing a trailer, so there is less shifting
between gears
When going down a steep hill
SECOND (2):This position gives you more power but
lower fuel economy than THIRD (3). You can use
SECOND (2) on hills. It can help control the vehicles
speed while going down steep mountain roads, but then
you would also want to use the brakes off and on.Notice:Driving in SECOND (2) for more than
25 miles (40 km) or at speeds over 55 mph (90 km/h)
may damage the transaxle. Also, shifting into
SECOND (2) at speeds above 65 mph (105 km/h) can
cause damage. Drive in THIRD (3) or AUTOMATIC
OVERDRIVE (D) instead of SECOND (2).
Notice:If your vehicle seems to start up rather
slowly, or if it seems not to shift gears as you go
faster, something may be wrong with a transaxle
system sensor. If you drive very far that way, your
vehicle can be damaged. So, if this happens,
have your vehicle serviced right away. Until then,
you can use SECOND (2) when you are driving less
than 35 mph (55 km/h) and THIRD (3) for higher
speeds.
FIRST (1):This position gives you even more power
but lower fuel economy than SECOND (2). You can use
it on very steep hills, or in deep snow or mud. If the
shift lever is put in FIRST (1), the transaxle will
not downshift into rst gear until the vehicle is going
slow enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transaxle. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes, or parking brake to hold the vehicle
in place.

Daytime Running Lamps (DRL)/
Automatic Headlamp System
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the
day. DRL can be helpful in many different driving
conditions, but they can be especially helpful in the short
periods after dawn and before sunset. Fully functional
Daytime Running Lamps are required on all vehicles rst
sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it is not covered. The DRL
system will make front parking and turn signal lamps
come on in daylight when the following conditions
are met:
The ignition is on.
The exterior lamps control is off.
When the DRL are on, only your front turn signal lamps
will be on. Your instrument panel will not be lit up.When it is dark enough outside, the exterior lamps will
come on automatically. When it is bright enough
outside, the exterior lamps will turn off and the DRL will
turn on. Of course, you may still turn on the headlamps
any time you need to.
If you start your vehicle in a dark garage, the automatic
headlamp system will come on immediately. Once
you leave the garage, it will take approximately
30 seconds for the automatic headlamp system to
change to DRL if it is light outside. During that delay,
your instrument panel cluster may not be as bright
as usual. Make sure your instrument panel brightness
control is in the full bright position. SeeInstrument Panel
Brightness on page 3-17.
To idle your vehicle with the DRL and automatic
headlamps off, toggle the exterior lamp control to off
after starting the vehicle.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

Ultrasonic Rear Parking
Assist (URPA)
If your vehicle is equipped with the Ultrasonic Rear
Parking Assist (URPA) system, it is designed to help you
park, while the vehicle is in REVERSE (R). It operates
only at very low speeds, less than 3 mph (5 km/h).
URPA can help make parking easier and to help you
avoid colliding with objects such as parked vehicles. The
URPA system can detect objects up to 5 feet (1.5 m)
behind the vehicle, and tell you how close these objects
are from your rear bumper.
Your vehicle’s URPA operates when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). Four ultrasonic sensors located
at the rear bumper are used to detect the distance to the
object. The URPA display is located inside the vehicle,
near the rear window. It has three color-coded lights
used to provide distance and system information to the
driver.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully before
backing up. The system does not operate
above typical backing speeds of 3 mph
(5 km/h) while parking. And, the system does
not detect objects that are more than 5 feet
(1.5 meters) behind the vehicle.
So, unless you check carefully behind you
before and when you back up, you could strike
children, pedestrians, bicyclists or pets behind
you, and they could be injured or killed.
Whether or not you are using rear park assist,
always check carefully behind your vehicle
before you back up and then watch closely as
you do.
3-21

URPA can be turned off by
pressing the rear park aid
disable switch located
in the overhead console
switchbank. While the
system is disabled,
an indicator light will be lit
on the switch. You will
not see any lights on the
rear display if the switch is
in the off position.
How the System Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let you know
that the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h),
the red light will ash to remind you that the system
does not work at speed greater than 3 mph (5 km/h).If an object is detected at a REVERSE (R) speed of
less than 3 mph (5 km/h), one of the following will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.
URPA cannot detect objects that are above liftgate level.
In order for the rear sensors to recognize an object, it
must be within detection range behind the vehicle.
3-22

When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck. If after cleaning the
rear bumper and then driving forward at least 15 mph
(25 km/h), the display continues to ash red, see
your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven forward
at least 15 mph (25 km/h) without any obstructions
behind the vehicle.
Accessory Power Outlets
Your vehicle may be equipped with a front accessory
power outlet located below the climate controls on
the instrument panel. It can be used to plug in electrical
equipment such as a cellular telephone or CB radio.Pull the cover down to use the accessory power outlet.
When not in use, keep the cover on.
The rear accessory power outlet is located on the rear
compartment on the driver’s side.
To remove the cover, pull the tab on the cover and pull
it off. To put the cover back on, line up the tabs at
the back of the cover and put the cover in place. Push
down the tab to secure the cover. When not in use,
always cover the rear accessory power outlet with the
protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible
with the accessory power outlet and could result
in blown vehicle or adapter fuses. If you experience a
problem see your dealer for additional information
on accessory power outlets.
Notice:Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Do not use equipment
exceeding maximum amperage rating. Check
with your dealer before adding electrical equipment.
