2001 CHEVROLET MONTE CARLO sensor

1-8 Split Folding Rear Seat
You can fold either side of the seatback (or both sides)
down in your vehicle for more cargo space. Make sure
the front seat isn't reclined. If it is, the rear seatback
may not fold down all the way.
There is a tab located
on the outboard sides
of the seatbacks.To lower either of the rear seatbacks, follow these steps:
1. Pull forward on the seat tab to unlock the seatback.
2. Fold the seatback down. This will allow you direct
access to the trunk.
To raise either of the rear seatbacks, lift the seatback up
and push it back into place. Make sure it latches. Push
and pull on the seatback to be sure it is locked into
position. When the seat is not in use, it should be kept in
the upright locked position.
If you plan to load items into the trunk through the split
folding rear seat, you must first turn off the trunk release
sensor. See ªTrunk Release Sensorº in the Index for
more information.

CAUTION:
When an air bag inflates, there is dust in the air.
This dust could cause breathing problems for
people with a history of asthma or other
breathing trouble. To avoid this, everyone in the
vehicle should get out as soon as it is safe to do so.
If you have breathing problems but can't get out
of the vehicle after an air bag inflates, then get
fresh air by opening a window or a door.
Your vehicle has a feature that will automatically unlock
the doors and turn the interior lamps on when the air
bags inflate (if battery power is available). You can lock
the doors again and turn the interior lamps off by using
the door lock and interior lamp controls.
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.

Trunk Release Sensor TrapAlert
System
(If Equipped)
Your vehicle may have a sensor located on the underside
of the filler panel inside the trunk.The sensor is designed to open the trunk automatically.
If the sensor detects motion and a difference in
temperature in the trunk, the sensor will sound the horn
if the ignition is in OFF. There will be three short chirps
and a pause repeated for up to two minutes. After one
minute, the trunk latch will release. If the ignition is not
in OFF, the trunk latch will not release automatically
and the horn will not sound.
To cancel the horn alarm and automatically release
the trunk lid before two minutes are up, turn the
ignition to ON.
Do not cover the sensor with items you put into the
trunk or with add
-on accessory equipment. If the
sensor's field of view is blocked, it will not detect
motion and will not function properly.
Be sure to secure items in your trunk so that they won't
move around and cause the trunk to open.

Disabling the Trunk Release Sensor
A. Sensor Lens
B. Disable SwitchBecause the sensor detects motion, there are times when
you may want to turn off the trunk sensor so that the
motion of your vehicle or items in the trunk won't cause
the trunk to open, such as the following:

when your vehicle is transported on a car ferry,

when your vehicle is towed, or

when you will be loading items through the opening
in the split folding rear seat (if equipped).
Next to the sensor lens, there is a disable switch you can
use to turn off the trunk release sensor. To turn off the
sensor, turn the ignition to ON and press the switch next to
the lens for two seconds. The horn will chirp once when
the sensor is turned off. When the sensor is off, the light in
the switch will flash. The TRUNK OPEN message in the
message center will flash for one minute each time the
ignition is turned on as a reminder that the sensor is turned
off. See ªTrunk Open Messageº in the Index.
To turn the sensor on again, press the switch again or open
the trunk. When the trunk is opened, the sensor is
automatically turned back on. If the sensor is turned back
on with the disable switch, the horn will chirp once.

2-17
Servicing the Trunk Release Sensor
The sensor lens should be inspected periodically.
If the lens is dirty, wipe it gently with a clean, soft
cotton cloth.
If there is an electrical problem with the sensor, the
SERVICE VEHICLE SOON message will appear in the
message center. There are other possible reasons for this
message to appear. Be sure to see your dealer as soon as
possible. See ªService Vehicle Soon Messageº in the
Index for more information.
Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft
-deterrent
features, we know that nothing we put on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it's an
easy target for joy riders or professional thieves
-- so
don't do it.
When you park your vehicle and open the driver's door,
you'll hear a chime reminding you to remove your key
from the ignition and take it with you. Always do this.
Your ignition and transaxle will be locked. And
remember to lock the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.

NEUTRAL (N): In this position, your engine
doesn't connect with the wheels. To restart when you're
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
CAUTION:
Shifting out of PARK (P) or NEUTRAL (N) while
your engine is ªracingº (running at high speed) is
dangerous. Unless your foot is firmly on the
brake pedal, your vehicle could move very
rapidly. You could lose control and hit people or
objects. Don't shift out of PARK (P) or
NEUTRAL (N) while your engine is racing.
NOTICE:
Damage to your transaxle caused by shifting out
of PARK (P) or NEUTRAL (N) with the engine
racing isn't covered by your warranty.
AUTOMATIC OVERDRIVE (
): 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 pedal 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 (
) for higher speeds.

Exterior Lamps
The lamp controls are located on the instrument panel.
They control the following systems:

Headlamps

Taillamps

Parking Lamps

License Lamps

Instrument Panel Lights

Dome LampIf you pull the knob out halfway, it will turn on your
parking lamps and your other operating lamps. If you
pull the knob all the way out, your headlamps will then
come on.
Push the knob in all the way to turn off the lamps.
A warning chime will sound if you open the driver's
door when you turn the ignition switch to OFF with
the lamps on.
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 lights 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.
