2007 CADILLAC STS parking brake

Twilight Sentinel®
Twilight Sentinel®can turn your lamps on and off
for you.
A light sensor on top of the instrument panel
makes the Twilight Sentinel
®work, so be sure it is
not covered.With Twilight Sentinel
®the following will happen:
When it is dark enough outside, the front
turn signal lamps (DRL) will go off, and
the headlamps and parking lamps will come
on. The other lamps that come on with
headlamps will also come on.
When it is bright enough outside, the
headlamps will go off, and the front turn signal
lamps (DRL) will come on, as long as the
exterior lamp switch is in the off position.
If you start your vehicle in a dark garage, the
automatic headlamp system will come on
immediately. Once you leave the garage, it will
take about one minute for the automatic headlamp
system to change to DRL if it is light outside.
During that delay, the instrument panel cluster
might not be as bright as usual. Make sure
the instrument panel brightness control is in full
bright position. SeeInstrument Panel Brightness
on page 220for more information.
You can idle the vehicle with the lamps off, even
when it is dark outside. First set the parking
brake while the ignition is in OFF/ACCESSORY.
Then start the vehicle. The lamps will stay off until
the parking brake is released.

Brake System Warning Light
Your vehicle’s hydraulic brake system is divided
into two parts. If one part isn’t working, the
other part can still work and stop you. For good
braking, though, you need both parts working well.
If the warning light comes on, there is a brake
problem. Have your brake system inspected
right away.
This light should come on briey when you turn
the engine on. If it does not come on then, have it
xed so it will be ready to warn you if there is a
problem.When the ignition is on, the brake system warning
light will also come on when you set your
parking brake. The light will stay on if your parking
brake does not release fully. If it stays on after
your parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull off
the road and stop carefully. You may notice
that the pedal is harder to push, or the pedal may
go closer to the oor. It may take longer to
stop. If the light is still on, have the vehicle towed
for service. SeeTowing Your Vehicle on
page 355.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.

Panic Brake Assist
Your vehicle has a panic brake assist system that
monitors the intention of the driver while braking. If
the system senses that the driver has applied
hard/fast pressure to the brake pedal, the system
will generate additional pressure, making it easier
for the driver to maintain brake application. When
this happens the brake pedal will feel easier to
push. Just hold the brake pedal down rmly and let
the system work for you. You may feel the brakes
vibrate, or you may notice some noise but this is
normal. The brakes will return to normal operation
after the brake pedal has been released.
All-Wheel Drive (AWD) System
If your vehicle is equipped with this feature, engine
power is sent to all four wheels all the time.
This is like four-wheel drive, but it is fully
automatic.
Steering
Power Steering
If you lose power steering assist because the
engine stops or the system is not functioning, you
can steer but it will take much more effort.
Speed Variable Assist Steering
Your vehicle has a steering system that
continuously adjusts the effort you feel when
steering at all vehicle speeds. It provides ease
when parking, yet a rm, solid feel at highway
speeds.
Steering Tips
It is important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned
on the news happen on curves. Here is why:
Experienced driver or beginner, each of us is
subject to the same laws of physics when driving on
curves. The traction of the tires against the road
surface makes it possible for the vehicle to change
its path when you turn the front wheels. If there is
no traction, inertia will keep the vehicle going in the
same direction. If you have ever tried to steer a
vehicle on wet ice, you will understand this.

3. Set the parking brake and then remove the key.
4. Clamp the steering wheel in a straight-ahead
position with a clamping device designed for
towing.
5. Release the parking brake.
Dolly Towing (STS-V)
Notice:Dolly towing or dinghy towing your
vehicle may cause damage because of reduced
ground clearance. Always put your vehicle
on a atbed truck.
If you have an STS-V, it can only be towed on a
at-bed trailer.
Dolly Towing (All-Wheel-Drive Vehicles)
Notice:Towing an all-wheel-drive vehicle
with all four wheels on the ground, or even
with only two of its wheels on the ground, will
damage drivetrain components. Do not tow
an all-wheel-drive vehicle if any of its wheels
will be on the ground.
If you have an All-Wheel Drive (AWD) vehicle, it
can only be towed on a at-bed trailer.
Towing a Trailer
Your vehicle is neither designed nor intended to
tow a trailer.

{CAUTION:
Batteries can hurt you. They can be
dangerous because:
They contain acid that can burn you.
They contain gas that can explode
or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly,
some or all of these things can hurt you.
Notice:Ignoring these steps could result in
costly damage to your vehicle that would
not be covered by your warranty.
Trying to start your vehicle by pushing or
pulling it will not work, and it could damage
your vehicle.
1. Check the other vehicle. It must have a
12-volt battery with a negative ground system.Notice:If the other vehicle’s system is not a
12-volt system with a negative ground,
both vehicles can be damaged. Only use
vehicles with 12-volt systems with negative
grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper
cables can reach, but be sure the vehicles are
not touching each other. If they are, it could
cause a ground connection you do not
want. You would not be able to start your
vehicle and the bad grounding could damage
the electrical systems.
To avoid the possibility of the vehicles rolling,
set the parking brake rmly on both vehicles
involved in the jump start procedure. Put
an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL before
setting the parking brake.

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.

Lifting Your Vehicle (STS-V)
{CAUTION:
Lifting a vehicle can cause an injury. The
vehicle can slip off the jack and roll over
you or other people. You and they could
be badly injured. Find a level place to lift
your vehicle. To help prevent the vehicle
from moving:
1. Hold the brake pedal down with your
right foot.
2. Move the shift lever in PARK (P) by
pressing the button on the front of
the shift lever while pushing the lever
all the way toward the front of the
vehicle. Release the button.
3. With your right foot still holding the
brake pedal down, set the parking
brake with your left foot.
4. Turn off the engine.
CAUTION: (Continued)
CAUTION: (Continued)
To be even more certain the vehicle will
not move, you can put blocks in front of
and behind the wheels. Also, seeShifting
Into Park (P) on page 122andParking
Brake on page 121for additional
information.
{CAUTION:
Getting under a vehicle when it is jacked
up is dangerous. If the vehicle slips off
the jack, you could be badly injured or
killed. Never get under a vehicle when it is
supported only by a jack.

Changing a Flat Tire
If you have an STS-V model, there is no spare tire
and no tire changing equipment. Your vehicle is
equipped with run-at tires. SeeRun-Flat
Tires (STS-V) on page 429for more information. If
you have an STS model, your vehicle may be
equipped with a tire inator kit. SeeTire Inator Kit
on page 452for more information. If your vehicle
is not equipped with a tire inator kit, follow
the directions for changing a at tire in this section.
If a tire goes at, avoid further tire and wheel
damage by driving slowly to a level place. Turn on
your vehicle’s hazard warning ashers. See
Hazard Warning Flashers on page 180for more
information.{CAUTION:
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1. Set the parking brake rmly.
2. Put the shift lever in PARK (P).
3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle will
not move, you should put blocks at the
front and rear of the tire farthest away
from the one being changed. That would
be the tire, on the other side, at the
opposite end of the vehicle.
