2009 CADILLAC CTS battery

A wet seat can affect the performance of the passenger
sensing system. Here is how:
The passenger sensing system may turn off the
passenger airbag when liquid is soaked into the
seat. If this happens, the off indicator will be lit,
and the airbag readiness light on the instrument
panel will also be lit.
Liquid pooled on the seat that has not soaked in
may make it more likely that the passenger
sensing system will enable (turn on) the passenger
airbag while a child restraint or child occupant is
on the seat. If the passenger airbag is turned on, the
on indicator will be lit.
If the passenger seat gets wet, dry the seat immediately.
If the airbag readiness light is lit, do not install a child
restraint or allow anyone to occupy the seat. SeeAirbag
Readiness Light on page 3-36for important safety
information.
{CAUTION:
Stowing of articles under the passenger seat or
between the passenger seat cushion and seatback
may interfere with the proper operation of the
passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how the vehicle should be serviced.
There are parts of the airbag system in several places
around the vehicle. Your dealer/retailer and the
service manual have information about servicing the
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition 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.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
This vehicle has theft-deterrent features, however,
they do not make it impossible to steal.
Theft-Deterrent System
If your vehicle has this
feature, the security light is
located on the instrument
panel cluster.
To activate the theft-deterrent system:
1. Open the door.
2. Lock the door with the transmitter. The security light
should come on and stay on.
3. Close all doors. The security light should go off
after about 30 seconds. The alarm is not armed
until the security light goes off.If a locked door or trunk is opened without using the
key in the driver’s door key cylinder or the transmitter, a
ten second pre-alarm will occur. The horn will chirp and
the lights will ash. If the key is not placed in the ignition
and turned to START or the door is not unlocked by
pressing the unlock button on the transmitter during the
ten second pre-alarm, the alarm will go off. Your vehicle’s
headlamps will ash and the horn will sound for about
30 seconds, then will turn off to save the battery power.
The theft-deterrent system will not activate if the doors
are locked with the vehicle’s key or the manual door lock.
It activates only if the power door lock switch is used
while the door is open or with the transmitter. You should
also remember that you can start your vehicle with the
correct ignition key if the alarm has been set off.
To avoid setting off the alarm by accident:
Lock the vehicle with the door key after the doors
are closed.
Always unlock a door with the transmitter. Unlocking
a door any other way will set off the alarm.
If you set off the alarm by accident, turn off the alarm by
pressing the unlock button on the transmitter. The alarm
will not stop if you try to unlock a door any other way.

Ignition Positions (Key Access)
The key can be turned to four different positions.
To shift out of P (Park), the ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
Notice:Using a tool to force the key from its
cylinder could cause damage or break the key. Use
the correct key and turn the key only with your hand.
Make sure the key is all the way in. If it is and you
have a manual transmission vehicle, turn the steering
wheel left and right while you turn the key hard. If
none of this works, then the vehicle needs service.A (LOCK/OFF):This is the only position in which the
key can be inserted or removed. This position locks the
ignition and shifter on automatic transmission vehicles,
and the ignition and steering wheel on manual
transmission vehicles.
B (ACC/ACCESSORY):This position lets you use
things like the radio and the windshield wipers when
the engine is off. This position allows you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
To shift the transmission out of P (Park), the ignition
key has to be in ACC/ACCESSORY or ON/RUN.
The battery could be drained if the key is left in the
ACC/ACCESSORY or ON/RUN position with the
engine off. The vehicle might not start if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.
