2007 CHEVROLET UPLANDER sensor

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 has 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.Frontal airbags may inate at different crash
speeds. For example:
If the vehicle hits a stationary object, the
airbags could inate at a different crash speed
than if the vehicle hits a moving object.
If the vehicle hits an object that deforms, the
airbags could inate at a different crash
speed than if the vehicle hits an object that
does not deform.
If the vehicle hits a narrow object (like a pole),
the airbags 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 airbags could inate at a different crash
speed than if the vehicle goes straight into the
object.
The frontal airbags (driver and right front
passenger) are not intended to inate during
vehicle rollovers, rear impacts, or in many side
impacts.

Passenger Sensing System
Your vehicle has a passenger sensing system.
The passenger airbag status indicator on the
instrument panel will be visible when you turn your
ignition key to RUN or START.
The words ON and OFF or the symbol for on and
off, will be visible during the system check.
When the system check is complete, either the
word ON or the word OFF, or the symbol for on or
the symbol for off will be visible. SeePassenger
Airbag Status Indicator on page 235.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 airbags or the second row
side impact airbags (if equipped) 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. We recommend 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.

{CAUTION:
For up to 10 seconds after the ignition key
is turned off and the battery is
disconnected, an airbag can still inate
during improper service. You can be
injured if you are close to an airbag when
it inates. Avoid yellow connectors. They
are probably part of the airbag system. Be
sure to follow proper service procedures,
and make sure the person performing
work for you is qualied to do so.
The airbag system does not need regular
maintenance.
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, height,
front end or side sheet metal, 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 556.

SECOND (2):This position reduces vehicle speed
more than DRIVE (D) without using your brakes.
You can use SECOND (2) on hills. It can help
control your speed as you go down steep mountain
roads, but then you would also want to use your
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 DRIVE (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 reduces vehicle speed
even more than SECOND (2) without using
your brakes. You can use it on very steep hills, or
in deep snow or mud. If the shift lever is put in
FIRST (1) while the vehicle is moving forward, the
transaxle will not shift into rst gear until the
vehicle is going slowly 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.

Wiper Activated Headlamps
This feature, if equipped, will automatically
activate the headlamps and parking lamps after
the windshield wipers have been in use for
about 30 seconds and when all of the following
conditions are met.
The exterior lamp control is in AUTO.
The headlamps have not already been
activated by automatic lighting.
The automatic lighting feature has not been
disabled using the exterior lamp control.
SeeExterior Lamps on page 204for additional
information.
If the wipers are activated for over 30 seconds
and the exterior lamp control is in the parking
lamps position, or the automatic lighting feature
has been disabled using the exterior lamp control,
a HEADLAMPS SUGGESTED message will
appear on the Driver Information Center, if
equipped.
Headlamps on Reminder
If you turn the ignition to LOCK while leaving the
lamps on, you will hear a warning chime once
the driver’s door is opened.
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.

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:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of 3 mph
(5 km/h).
Detect objects more than 5 feet
(1.5 meters) behind the vehicle. This
distance may be less during warmer
or humid weather.
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.
212

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.
213

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 Outlet(s)
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 of
20 amperes.
