Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheat
and damage the cranking motor, and drain the
battery. Wait at least 15 seconds between each try,
to let the cranking motor cool down.
2. If the engine does not start after 5‐10 seconds, especially in very cold weather (below 0°F or
−18°C), it could be flooded with too much gasoline.
Try pushing the accelerator pedal all the way to
the floor and holding it there as you hold the key in
START for up to a maximum of 15 seconds. Wait
at least 15 seconds between each try, to allow the
cranking motor to cool down. When the engine
starts, let go of the key and accelerator. If the
vehicle starts briefly but then stops again, repeat
these steps. This clears the extra gasoline from the
engine. Do not race the engine immediately after
starting it. Operate the engine and transmission
gently until the oil warms up and lubricates all
moving parts. Notice:
The engine is designed to work with the
electronics in the vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you do not,
the engine might not perform properly. Any
resulting damage would not be covered by the
vehicle warranty.
Engine Coolant Heater
The engine coolant heater can provide easier starting
and better fuel economy during engine warm‐up in cold
weather conditions at or below 0°F (−18°C). Vehicles
with an engine coolant heater should be plugged in at
least four hours before starting.

To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.The electrical cord is located on the driver side of
the engine, behind the transmission dipstick/fluid
fill location and next to the engine.
3. Plug it into a normal, grounded 110-volt AC outlet.
{WARNING:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a fire.
You could be seriously injured. Plug the cord into
a properly grounded three-prong 110-volt AC
outlet. If the cord will not reach, use a heavy-duty
three-prong extension cord rated for at least
15 amps.
4. Before starting the engine, be sure to unplug and store the cord as it was before to keep it away from
moving engine parts and prevent damage. The length of time the heater should remain plugged in
depends on several factors. Ask a dealer in the area
where you will be parking the vehicle for the best advice
on this.
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.
P (Park):
This position locks the front wheels. It is the
best position to use when you start the engine because
the vehicle cannot move easily.
3-26

Black plate (27,1)Cadillac DTS Owner Manual - 2011
{WARNING:
It is dangerous to get out of the vehicle if the shift
lever is not fully in P (Park) with the parking brake
firmly 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 3‑30. If you are pulling a trailer,
see Towing a Trailer on page 5‑26. Make sure the shift lever is fully in P (Park) before
starting the engine. The vehicle has an automatic
transmission shift lock control system. You have to
fully apply the regular brakes before you can shift from
P (Park) while the ignition key is in ON/RUN. If you
cannot shift out of P (Park), ease pressure on the shift
lever. Push the shift lever all the way into P (Park) as
you maintain brake application. Then move the shift
lever into another gear. See
Shifting Out of Park
on
page 3‑32.
R (Reverse): Use this gear to back up.
Notice: Shifting to R (Reverse) while the vehicle is
moving forward could damage the transmission.
The repairs would not be covered by the vehicle
warranty. Shift to R (Reverse) only after the vehicle
is stopped.
Also use this gear to rock the vehicle back and forth
to get out of snow, ice or sand without damaging the
transmission. See If Your Vehicle is Stuck in Sand,
Mud, Ice, or Snow
on page 5‑17for additional
information.
3-27

N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. Also, use
N (Neutral) when the vehicle is being towed.
{WARNING:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless your
foot is firmly on the brake pedal, the vehicle could
move very rapidly. You could lose control and hit
people or objects. Do not shift into a drive gear
while the engine is running at high speed.
Notice: Shifting out of P (Park) or N (Neutral) with
the engine running at high speed may damage the
transmission. The repairs would not be covered by
the vehicle warranty. Be sure the engine is not
running at high speed when shifting the vehicle. D (Drive):
This position is for normal driving. It provides
the best fuel economy for the vehicle. If you need more
power for passing, and you are:
.Going less than 35 mph (55 km/h), push the
accelerator pedal about halfway down.
.Going about 35 mph (55 km/h) or more, push the
accelerator all the way down.
The transmission will shift down to the next gear
and have more power.
Downshifting the transmission in slippery road
conditions could result in skidding, see Skidding under
Loss of Control on page 5‑10.
Notice: Driving the vehicle if you notice that it is
moving slowly or not shifting gears as you increase
speed may damage the transmission. Have the
vehicle serviced right away. You can drive in
2 (Second) when you are driving less than 35 mph
(55 km/h) and D (Drive) for higher speeds until then.
D (Drive) can be used for towing. You may want to shift
the transmission to 3 (Third) or, if necessary, to a lower
gear if the transmission shifts too often under heavy
loads and/or hilly conditions.
See Towing a Trailer
on page 5‑26for more
information.
3-28

3 (Third):This position is also used for normal driving.
However, it reduces vehicle speed more than D (Drive)
without using the brakes. You might choose 3 (Third)
instead of D (Drive) when driving on hilly, winding roads,
when towing a trailer, so there is less shifting between
gears and when going down a steep hill.
2 (Second): This position reduces vehicle speed more
than 3 (Third) without using the brakes. You can use
2 (Second) on hills. It can help control vehicle speed as
you go down steep mountain roads, but then you would
also want to use the brakes off and on.
Notice: Do not shift into 2 (Second) unless you are
going slower than 65 mph (105 km/h), or you can
damage the engine and/or transmission.
1 (First): This position reduces vehicle speed even
more than 2 (Second) without using the brakes. You can
use it on very steep hills, or in deep snow or mud. If the
shift lever is put in 1 (First) while the vehicle is moving
forward, the transmission will not shift into first 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 the vehicle 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 the 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.
Parking Brake
The parking brake pedal
is located to the left of the
regular brake pedal, near
the driver door.
To set the parking brake, hold the regular brake pedal
down, then push the parking brake pedal down.
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 the vehicle serviced.
3-29
Page 134 of 470

Black plate (30,1)Cadillac DTS Owner Manual - 2011
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. SeeBrake
System Warning Light
on page 4‑50for more
information.
To release the parking brake, hold the regular brake
pedal down, then push the parking brake pedal down.
When you lift your foot off the parking brake pedal, the
pedal will follow your foot 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,
see Towing a Trailer on page 5‑26.
Shifting Into Park
{WARNING:
It can be dangerous to get out of the vehicle if the
shift lever is not fully in P (Park) with the parking
brake firmly set. The vehicle can roll. 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, use the steps that follow.
If you are pulling a trailer, see Towing a Trailer
on
page 5‑26
.

4. Turn the ignition key to LOCK/OFF.
5. Remove the key and take it with you. If you can leave the vehicle with the ignition key in your hand,
the vehicle is in P (Park).
Leaving the Vehicle With the Engine
Running
{WARNING:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly
if the shift lever is not fully in P (Park) with the
parking brake firmly set. And, if you leave the
vehicle with the engine running, it could overheat
and even catch fire. You or others could be
injured. Do not leave the vehicle with the engine
running.
If you have to leave the vehicle with the engine running,
be sure your vehicle is in P (Park) and the parking
brake is firmly set before you leave it. See Parking
Brake
on page 3‑29for more information.
3-31

Torque Lock
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then
it is difficult to shift out of P (Park). To prevent torque
lock, set the parking brake and then shift into P (Park).
To find out how, see“Shifting Into Park”in this section.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
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 P (Park)
.Prevent movement of the shift lever out of P (Park),
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 the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
See
Jump Starting on page 6‑38.
Console Shift
If the console shift cannot be moved out of P (Park)
1. Apply the regular brakes.
2. Turn the ignition to ON/RUN or ACC/ACCESSORY position. See Ignition Positions
on page 3‑22for
more information.
3. Push the shift lever all the way into P (Park).
4. Then, shift into the desired gear.
