2008 Cadillac STS/STS-V Owner ManualM

The transmission will only allow you to shift into gears
appropriate for the vehicle speed and engine
Revolutions Per Minute (RPM). The transmission will
not automatically shift to the next higher gear if the
engine RPM is too high.
If shifting is prevented for any reason, the selected gear
will ash multiple times, indicating that the transmission
has not shifted gears.
The transmission will allow you to shift to the gear
selected and will automatically downshift when
the vehicle comes to a stop. This will allow for more
power during take-off and passing.
Parking Brake
The parking brake pedal
is located on the lower
portion of the instrument
panel to the left of the
steering wheel.This vehicle has a push-to-release parking brake pedal.
To set the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot.
If the ignition is on, the brake system warning light on
the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.
SeeBrake System Warning Light on page 3-64for
more information.
To release the parking brake, hold the brake pedal
down with your right foot and push the parking brake
pedal with your left foot. When you lift your left foot,
the parking brake releases.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Make sure
that the parking brake is fully released and the brake
warning light is off before driving.
A warning chime will sound if the parking brake is set,
the ignition is on and the vehicle begins to move.
To stop the chime, fully release the parking brake.
If you are towing a trailer and parking on a hill,
seeTowing a Trailer (Vehicles With Heavy Duty
Cooling) on page 4-34orTowing a Trailer (Vehicles
Without Heavy Duty Cooling) on page 4-40for
more information.

When the System Does Not Seem to
Work Properly
The ultrasonic sensors are not clean, a red URPA
display light may illuminate when the vehicle is in
REVERSE (R). Keep your rear bumper free of mud,
dirt, snow, ice and slush. For cleaning instructions,
seeWashing Your Vehicle on page 5-110.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive cycle, the red light may illuminate.
Once the attached object is removed, URPA
will return to normal operation.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
Side Blind Zone Alert
Your vehicle may have a Side Blind Zone Alert (SBZA)
system. The SBZA system is an aid that may help
you avoid lane change crashes with vehicles in your side
blind spots (zones). Read the entire section before
using the system. See “Side Blind Zone Alert” in
the Index of the navigation manual.
Lane Departure Warning
Your vehicle may have a Lane Departure Warning
(LDW) system. The LDW system does not steer the
vehicle and is only an aid to help you stay in your driving
lane. Read the entire section before using the system.
See “Lane Departure Warning” in the Index of the
navigation manual.

Raise or lower the lever until the arrow starts to ash
to signal a lane change. Hold it briey until the lane
change is complete. The arrow will automatically ash
three times The lever returns to its original position
when it is released.
Rapid ashing of arrows when signaling for a turn
or lane change can be caused by a burned-out signal
bulb. Other drivers will not see the signal.
Replace burned-out bulbs to help avoid possible
accidents. Check the fuse for burned-out bulbs
if the arrow fails to work when signaling a turn.
SeeFuses and Circuit Breakers on page 5-117
for more information.
Turn Signal On Chime
If the turn signal is left on for about 1 mile (1.6 km),
a warning chime will sound and the TURN SIGNAL
ON message will appear on the Driver Information
Center (DIC) display. See “Turn Signal On” under
DIC Warnings and Messages on page 3-80for
more information.
Headlamp High/Low-Beam Changer
Push forward on the turn signal/multifunction lever
to change the headlamps from low to high beam.
Pull the lever back and then release it to change
from high to low beam.
If you turn the vehicle off with the high beams on,
the next time you start your vehicle the low beams
will be on.
To re-activate high beams, pull lever toward you and
then push it forward again.
This light on the
instrument panel cluster
will be on, indicating
high-beam usage.

Wiper Activated Headlamps
This feature activates the headlamps and parking lamps
after the windshield wipers have been in use for
about six seconds. For this feature to work, automatic
lighting must be enabled. SeeHeadlamps on page 3-33
for additional information.
When the ignition is turned off, the wiper-activated
headlamps will immediately turn off. They will also turn
off if the windshield wiper control is turned off.
Headlamps on Reminder
A warning chime will sound if the exterior lamp control
is left on in either the headlamp or parking lamp position
and the driver’s door is opened with the ignition off.
SeeLights On Reminder on page 3-72for additional
information.
Daytime Running Lamps (DRL)
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.
The DRL system will make the turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on,
the automatic lights are enabled, and
the transmission is not in PARK (P).
When DRL are on, only the front turn signal lamps will
be on. No other exterior lamps will be on when the DRL
are being used. The instrument panel will not be lit.
When the automatic lights are enabled and it is dark
enough outside, the DRL will turn off and the low-beam
headlamps will turn on. When it is bright enough
outside, the low-beam headlamps will go off, and the
DRL will turn back on. If the vehicle is started in a
dark garage, the automatic headlamp system will
come on immediately. Once the vehicle leaves the
garage, it will take about one minute for the automatic
headlamp system to change to DRL if it is light outside.
