2002 CHEVROLET VENTURE sensor

1-53
In many crashes severe enough to inflate an air bag,
windshields are broken by vehicle deformation.
Additional windshield breakage may also occur from the
right front passenger air bag.

Air bags are designed to inflate only once. After an
air bag inflates, you'll need some new parts for your
air bag system. If you don't get them, the air bag
system won't be there to help protect you in another
crash. A new system will include air bag modules
and possibly other parts. The service manual for your
vehicle covers the need to replace other parts.

Your vehicle is equipped with an electronic frontal
sensor, which helps the sensing system distinguish
between a moderate frontal impact and a more
severe frontal impact. Your vehicle is also equipped
with a crash sensing and diagnostic module, which
records information about the frontal air bag system.
The module records information about the readiness
of the system, when the system commands air bag
inflation and driver's safety belt usage at
deployment. The module also records speed, engine
rpm, brake and throttle data.

Let only qualified technicians work on your air
bag systems. Improper service can mean that an
air bag system won't work properly. See your dealer
for service.
NOTICE:
If you damage the covering for the driver's or the
right front passenger's air bag, or the air bag
covering on the driver's and right front
passenger's seatback, the bag may not work
properly. You may have to replace the air bag
module in the steering wheel, both the air bag
module and the instrument panel for the right
front passenger's air bag, or both the air bag
module and seatback for the driver's and right
front passenger's side impact air bag. Do not
open or break the air bag coverings.

2-50
AUTOMATIC OVERDRIVE (D): This position is
for normal driving. If you need more power for passing,
and you're:

Going less than 35 mph (55 km/h), push your
accelerator pedal about halfway down.

Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
You'll shift down to the next gear and have more power.
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 AUTOMATIC
OVERDRIVE (D) for higher speeds.
Warm-Up Shift
Your vehicle has a computer controlled transaxle
designed to warm up the engine faster when the outside
temperature is 35F (2C) 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.
See ªComfort Controls, Heatingº in the Index for
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.

2-51
SECOND (2): This position gives you more power, but
lower fuel economy. 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:
Don't drive in SECOND (2) for more than
25 miles (40 km), or at speeds over 55 mph
(90 km/h), or you can damage your transaxle.
Use THIRD (3) or AUTOMATIC
OVERDRIVE (D) as much as possible. Don't
shift into SECOND (2) unless you are going
slower than 65 mph (105 km/h) or you can
damage your engine.
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.

2-68 Daytime Running Lamps / Automatic
Headlamp Control
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 first sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn't 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, and

the parking brake is released.
When the DRL are on, only your front parking and turn
signal lamps will be on. Your instrument panel won't be
lit up.
When it's dark enough outside, the exterior lamps will
come on automatically. When it's 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.To idle your vehicle with the DRL and automatic
headlamps off, set the parking brake while the ignition is
in OFF or LOCK. Then start the vehicle. The DRL and
automatic headlamps will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Interior Lamps
Instrument Panel Brightness Control
This feature controls the brightness of the instrument
panel lights.
The thumbwheel for this feature is located below the
exterior lamps control.
Turn the thumbwheel to the right to brighten the lights
or to the left to dim them. Turn the thumbwheel all the
way to the left to turn off the instrument panel lights.
Interior Lamps Control
Turn the thumbwheel all the way to the right to turn on
the interior lamps, if the interior lamps override switch
is off. Turn the thumbwheel to the left to turn the
lamps off.

2-104 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the air bag symbol. The system
checks the air bag's electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag sensor, the air bag
modules, the wiring and the diagnostic module. For
more information on the air bag system, see ªAir Bagº
in the Index.
This light will come on
when you start your vehicle,
and it will flash for a few
seconds. Then the light
should go out. This means
the system is ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air bag
system may not work properly. Have your vehicle
serviced right away.
CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.

Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases the calibration symbol C will be displayed
where the compass reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make three 360
turns. The calibration
symbol will turn off and the compass reading will
be displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for at least 10 seconds
until the calibration symbol appears. Release both
buttons and complete three 360
turns in an area free
from large metal objects. The calibration symbol will
turn off and the compass reading will be displayed.Error Displays

An error of the vehicle's speed sensor or fuel sender
will cause
-E- to be displayed.

In the absence of vehicle communications, a
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.
Trip Computer
There are five trip computer displays which may be
stepped through by pressing the MODE button. The
information will appear in the following order:

AVG ECON (Average Fuel Economy): This shows
the average fuel economy since the last reset.

INST ECON (Instantaneous Fuel Economy): This
shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.

2-124 How the System Works
If the rear park aid disable switch is not on, the rear
parking assist turns on automatically when the shift
lever is moved into REVERSE (R) and the vehicle
speed is less than 3 mph (5 km/h). When the system
turns on, the three lights on the display will illuminate
for 1.5 seconds to let you know that the system is
working. Rear parking assist senses how close your
vehicle is to an object. The distance is determined by the
four ultrasonic sensors located on the rear bumper.
When shifting into REVERSE (R) and an object is
detected, one of the following will occur:

Amber/amber/red lights flashing and
continuous chime 1 ft. (0.3 m). . . . . . . . . . . . . . . . .

Amber/amber/red lights and
continuous chime 20 in. (0.5 m). . . . . . . . . . . . . . . .

Amber/amber lights 40 in. (1.0 m). . . . . . . . . . . . . .

Amber light 5 ft. (1.5 m). . . . . . . . . . . . . . . . . . . . .
A chime will sound the first time an object is detected,
if the object is between 20 inches (0.5 cm) and
5 feet (1.5 m) away.
Rear parking assist can detect objects 3 inches (7.6 cm)
and wider, and at least 10 inches (25.4 cm) tall, but it
cannot detect objects that are above liftgate level. In
order for the rear sensors to recognize an object, it must
be within operating range.If the rear parking assist system is not functioning
properly, the display will flash red, indicating that there is
a problem, unless the disable switch is on. The light will
also flash red when the vehicle is shifting into
REVERSE (R), if a trailer was attached to your vehicle,
or if a bicycle or an object was on the back of, or hanging
out of your liftgate during your last drive cycle. The light
will continue to flash whenever in REVERSE (R) until
your vehicle is driven forward at least 15 mph (25 km/h)
without any obstructions behind the vehicle.
It will also flash red if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush or the system may not work
properly. If after cleaning the rear bumper and driving
forward at least 15 mph (25 km/h), the display continues
to flash red, see your dealer.
It may also flash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
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.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
For cleaning instructions, see ªCleaning Your Vehicleº
in the Index.
