keyless CADILLAC STS V 2007 1.G Service Manual

Instrument Panel Brightness
This feature controls the
brightness of the
instrument panel lights.
Press in the center knob on the DIC control panel
until the knob pops out. Then turn the knob
clockwise to brighten the lights or counterclockwise
to dim them. If you turn the knob completely
clockwise, the interior lamps will turn on.
Entry Lighting
The entry lighting system turns on the reading and
dome lamps and the backlighting to the exterior
lamp control when a door is opened or if you
press the remote keyless entry transmitter
unlock button. If activated by the transmitter, the
lighting will remain active for about 25 seconds.
The entry lighting system uses the light sensor; it
must be dark outside in order for the lamps to
turn on. The lamps turn off about 25 seconds after
the last door is closed. They will dim to off if the
ignition is on, or immediately deactivate if the
power locks are activated.
Parade Dimming
This feature prohibits dimming of the instrument
panel displays and backlighting during daylight
hours when the key is in the ignition and the
headlamps are on. This feature operates with the
light sensor and is fully automatic. When the
light sensor reads darkness outside and the
parking lamps are active, the instrument panel
displays can be adjusted by turning the instrument
panel brightness knob. SeeInstrument Panel
Brightness on page 220for additional information.

Did you just drive through a deep puddle of water?
If so, your vehicle’s electrical system may be wet.
The condition will usually be corrected when
the electrical system dries out. A few driving trips
should turn the light off.
Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel.
SeeGasoline Octane on page 365. Poor fuel
quality will cause the engine not to run as
efficiently as designed. You may notice this as
stalling after start-up, stalling when you put
the vehicle into gear, misring, hesitation on
acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is
warmed up.) This will be detected by the system
and cause the light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at
least one full tank of the proper fuel to turn the
light off.
If none of the above steps have made the light
turn off, your dealer can check the vehicle.
Your dealer has the proper test equipment and
diagnostic tools to x any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have
or may begin programs to inspect the emission
control equipment on your vehicle. Failure to pass
this inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
check engine light is on or not working properly.
To perform a check engine light bulb check with the
keyless ignition, make sure the transmitter fob is in
the passenger compartment. SeeIgnition Positions
on page 111. Press the bottom of the Acc. button
on the instrument panel and hold the button down
for ve seconds. The instrument panel, including
the check engine light, will light up and the ignition
will be on, but the engine will not start — if you
press the bottom of the Acc. button only briey, less
than ve seconds, the accessory power mode will
be turned on, but not the ignition. After the bulb
check, be sure to press and release the Acc. button
again to turn the ignition off and avoid draining the
vehicle’s battery.

NO FOBS DETECTED
This message displays if the vehicle does not
detect the presence of a keyless access
transmitter when you have attempted to start the
vehicle or a vehicle door has just closed. The
following conditions may cause this message
to appear:
Driver-added equipment plugged into the
accessory power outlet on the center console
is causing interference. Examples of these
devices are cell phones and cell phone
chargers, two-way radios, power inverters, or
similar items. Try moving the keyless
access transmitter away from these devices
when starting the vehicle. In addition,
PDA devices and remote garage and gate
openers may also generate Electromagnetic
Interference (EMI) that may interfere with
the keyless access transmitter. Do not carry
the keyless access transmitter in the same
pocket or bag as these devices.
The vehicle is experiencing Electromagnetic
Interference (EMI). Some locations, such as
airports, automatic toll booths, and some
gas stations, have EMI elds which may
interfere with the keyless access transmitter.
If moving the transmitter
to different locations
within the vehicle does
not help, place the
transmitter in the center
console transmitter
pocket with the buttons
facing forward and
then press the
START button.
The vehicle’s battery voltage is low. The
battery voltage must be above 10 volts for
the keyless access transmitter to be
detected properly.

has been pressed or 10 minutes has expired.
If you turn the ignition off and you cannot nd the
keyless access transmitter, you will not be
able to restart the vehicle. The keyless access
transmitter needs to be inside of the vehicle
in order for the vehicle to start. SeeStarting the
Engine on page 113for more information.

Notice:If you drive your vehicle while
the engine oil pressure is low, severe engine
damage may occur. If a low oil pressure

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate your vehicle’s tires,
the identication codes will need to be matched to
the new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver side front tire, passenger side front
tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall. If
using this method to match TPMS sensors, the
complete procedure outlined below must be
performed within 15 minutes of the vehicle being
stationary.You will have one minute to match the rst
tire/wheel position, and ve minutes overall, to
match all four tire/wheel positions. If it takes longer
than one minute to match the rst tire and
wheel, or more than ve minutes to match all
four tire/wheel positions, the matching process
stops and you will need to start over.
The TPM matching process is outlined below:
1. Set the parking brake.
2. Press the push-button ignition switch to Acc.
(Off/Accessory).
3. Using the Keyless Access transmitter, lock
and unlock the vehicle’s doors.
4. Press the lock and unlock buttons, at the
same time, on the Keyless Access
transmitter. A single horn chirp will sound,
indicating that the TPMS is ready, and
the sensor matching process can begin.
5. Start with the driver’s side front tire.
