2008 Cadillac DTS Owner ManualM

{CAUTION:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger’s seat may not have the protection
of the airbag(s). SeeAirbag Readiness Light
on page 3-57for more on this, including
important safety information.A thick layer of additional material, such as a blanket or
cushion, or aftermarket equipment such as seat
covers, seat heaters, and seat massagers can affect
how well the passenger sensing system operates.
We recommend that you not use seat covers or other
aftermarket equipment other than any that GM has
approved for your specic vehicle. SeeAdding
Equipment to Your Airbag-Equipped Vehicle on
page 1-69for more information about modications that
can affect how the system operates.
{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.

To program the new key:
1. Verify that the new key has a
1stamped on it.
2. Insert the original, already programmed, key in the
ignition and start the engine. If the engine will not
start, see your dealer/retailer for service.
3. After the engine has started, turn the key to
LOCK/OFF, and remove the key.
4. Insert the new key to be programmed and turn it to
the ON/RUN position within ve seconds of
removing the original key.
The security light will turn off once the key has
been programmed.
5. Repeat Steps 1 through 4 if additional keys are to
be programmed.
If you lose or damage your PASS-Key
®III+ key, see
your dealer/retailer or a locksmith who can service
PASS-Key
®III+ to have a new key made.
Do not leave the key or device that disarms or
deactivates the theft deterrent system in the vehicle.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Do not drive at any one constant speed, fast or
slow, for the rst 500 miles (805 km). Do not
make full-throttle starts. Avoid downshifting to
brake or slow the vehicle.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time the new brake
linings are not yet broken in. Hard stops
with new linings can mean premature wear and
earlier replacement. Follow this breaking-in
guideline every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing
a Trailer on page 4-27for the trailer towing
capabilities of your vehicle and more
information.
Following break-in, engine speed and load can be
gradually increased.
2-22

Automatic Transmission Operation
The automatic transmission may have a shift lever
located either on the steering column or on the console
between the seats.
There are several different positions for the shift lever.
PARK (P):This position locks the front wheels. It is the
best position to use when you start the engine because
your vehicle cannot move easily.{CAUTION:
It is dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the
parking brake rmly set. The vehicle can roll.
Do not leave the vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure the
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
and move the shift lever to P (Park). SeeShifting
Into Park on page 2-31. If you are pulling a
trailer, seeTowing a Trailer on page 4-27.
Make sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You have to fully
apply your regular brakes before you can shift from
PARK (P) while the ignition key is in ON/RUN. If you
cannot shift out of PARK (P), ease pressure on the shift
lever. Push the shift lever all the way into PARK (P)
as you maintain brake application. Then move the shift
lever into another gear. SeeShifting Out of Park on
page 2-33.
2-27

Downshifting the transmission in slippery road conditions
could result in skidding, see Skidding underLoss of
Control on page 4-10.
Notice:Driving your vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have your
vehicle serviced right away. You can drive in
SECOND (2) when you are driving less than 35 mph
(55 km/h) and DRIVE (D) for higher speeds until then.
DRIVE (D) can be used for towing. You may want to
shift the transmission to THIRD (3) or, if necessary, to a
lower gear if the transmission shifts too often under
heavy loads and/or hilly conditions.
SeeTowing a Trailer on page 4-27for more information.
THIRD (3):This position is also used for normal driving.
However, it reduces vehicle speed more than DRIVE (D)
without using your brakes. You might choose THIRD (3)
instead of DRIVE (D) when driving on hilly, winding
roads, when towing a trailer, so there is less shifting
between gears and when going down a steep hill.
SECOND (2):This position reduces vehicle speed more
than THIRD (3) without using your brakes. You can
use SECOND (2) on hills. It can help control your speed
as you go down steep mountain roads, but then you
would also want to use your brakes off and on.Notice:Do not shift into SECOND (2) unless you
are going slower than 65 mph (105 km/h), or you can
damage your engine and/or transmission.
FIRST (1):This position reduces vehicle speed even
more than SECOND (2) without using your brakes.
You can use it on very steep hills, or in deep snow or
mud. If the shift lever is put in FIRST (1) while the
vehicle is moving forward, the transmission will not shift
into rst gear until the vehicle is going slowly enough.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. The repair will
not be covered by your warranty. If you are stuck,
do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Performance Shifting
If your vehicle has this feature, it can detect a change in
driving patterns. If you make an aggressive driving
maneuver, the vehicle’s transmission automatically
shifts to the lowest possible gear to maximize vehicle
performance. The vehicle will automatically return to
normal operation when you return to normal driving
patterns.
2-29

Parking Brake
The parking brake pedal is
located to the left of the
regular brake pedal,
near the driver’s door.
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.A warning chime will sound if the parking brake is set,
the ignition is on, and the vehicle speed is greater
than 5 mph (8 km/h). The brake light will come on and
stay on until the parking brake is released. See
Brake System Warning Light on page 3-60for more
information.
To release the parking brake, hold the regular brake
pedal down with your right foot and push the parking
brake pedal down with your left foot. When you lift your
left foot, the parking brake pedal will follow it to the
released position.
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.
If you are towing a trailer and are parking on any hill,
seeTowing a Trailer on page 4-27.
2-30

Shifting Into Park
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle will not move,
even when you are on fairly level ground, use
the steps that follow. If you are pulling a trailer,
seeTowing a Trailer on page 4-27.
Steering Column Shift Lever
If your vehicle has a steering column shift lever, use this
procedure to shift the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pulling the
shift lever toward you and moving it up as far as it
will go.3. With your right foot still holding the brake pedal
down, set the parking brake. SeeParking Brake
on page 2-30for more information.
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
Console Shift Lever
If your vehicle is equipped with a console shift lever,
use this procedure to shift the vehicle into PARK (P):
1. Hold the brake pedal down with your right foot.
2. Move the shift lever into PARK (P) by pushing the
lever all the way toward the front of your vehicle
and then to the left.
3. With your right foot still holding the brake pedal
down, set the parking brake. SeeParking Brake
on page 2-30for more information.
4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can
leave your vehicle with the ignition key in your
hand, your vehicle is in PARK (P).
2-31

Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever is
in PARK (P)
Prevent movement of the shift lever out of PARK (P),
unless the ignition is in ON/RUN or ACC/
ACCESSORY and the regular brake pedal is applied.
The shift lock is always functional except in the case of
a an uncharged or low voltage (less than 9 volt)
battery.
If your vehicle has an uncharged battery or a battery
with low voltage, try charging or jump starting the
battery. SeeJump Starting on page 5-42.
Console Shift
If your console shift cannot be moved out of PARK (P)
1. Apply and maintain the regular brakes.
2. Turn the ignition to ON/RUN or ACC/ACCESSORY
position. SeeIgnition Positions on page 2-23for
more information.3. Let up on the shift lever and make sure the shift
lever is pushed all the way into PARK (P).
4. Then, move the shift into the desired gear.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
Column Shift
If your park lock cable cannot be moved out of PARK (P)
1. Apply and maintain the regular brakes.
2. Turn the ignition key to the ON/RUN or
ACC/ACCESSORY position. SeeIgnition Positions
on page 2-23for more information.
3. Shift out of the PARK (P) position to the
NEUTRAL (N) position.
4. Move the vehicle to a safe location.
If you still cannot move the shift lever from PARK (P),
consult your dealer/retailer or a professional towing
service.
2-33

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier caution under
Engine Exhaust on page 2-34.
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the climate control fan is at the highest setting.
One place this can happen is a garage.
Exhaust — with CO — can come in easily.
NEVER park in a garage with the engine
running.
Also see “If You Are Caught in a Blizzard” under
Winter Driving on page 4-16.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake rmly set. Your vehicle can roll.
Do not leave your vehicle when the engine is
running unless you have to. If you have left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle will not move, even when you are on
fairly level ground, always set the parking brake
after you move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle will not
move. SeeShifting Into Park on page 2-31.
If you are parking on a hill and if you are pulling a
trailer, also seeTowing a Trailer on page 4-27.
2-35

The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modications to
this equipment. Such modications could void the user’s
authority to operate the equipment.
{CAUTION:
SBZA is only a lane changing aid and does not
replace driver vision. SBZA does not detect:
Vehicles outside the side blind zones
which may be rapidly approaching.
Pedestrians, bicyclists, or animals.
Failure to use proper care when changing
lanes may result in damage to the vehicle,
injury, or death. Always check the outside and
rearview mirrors, glance over your shoulder,
and use the turn signal before changing lanes.
When the system detects a vehicle in the side blind zone,
amber SBZA displays will light up in your side mirrors.
This indicates that it may be unsafe for you to change
lanes. Before making a lane change, always check the
SBZA display, check the outside and rearview mirrors,
look over your shoulder for vehicles and hazards, and
use the turn signal.
SBZA Detection Zones
The SBZA sensor covers a zone of approximately one
lane over from both sides of the vehicle, 11 ft. or 3.5 m.
This zone starts at each side mirror and goes back
approximately 16 ft. (5.0 m). The height of the zone is
approximately between 1.5 ft. (0.5 m) and 6 ft. (2.0 m) off
the ground.
The SBZA detection zones do not change if your
vehicle is towing a trailer. So be extra careful when
changing lanes while towing a trailer.
