ignition CADILLAC DTS 2009 1.G Owner's Manual

The vehicle has a Computer-Controlled Cranking
System. This feature assists in starting the
engine and protects components. If the ignition
key is turned to the START position, and then
released when the engine begins cranking, the
engine will continue cranking for a few seconds or
until the vehicle starts. If the engine does not
start and the key is held in START, cranking will be
stopped after 15 seconds to prevent cranking
motor damage. To prevent gear damage, this
system also prevents cranking if the engine
is already running. Engine cranking can be
stopped by turning the ignition switch to the
ACC/ACCESSORY or LOCK/OFF position.
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 ooded with too much gasoline.
Try pushing the accelerator pedal all the way to
the oor 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 briey 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/retailer. If you do not, the
engine might not perform properly. Any resulting
damage would not be covered by the vehicle
warranty.

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.{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 2-33. If you are pulling a trailer,
seeTowing a Trailer on page 4-28.
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. SeeShifting Out of Park on
page 2-34.

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.
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 3-56for 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,
seeTowing a Trailer on page 4-28.

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 nd 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

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase the vehicle speed.
When you take your foot off the pedal, the vehicle
slows down to the previous cruise control speed.
Using Cruise Control on Hills
How well your cruise control works on hills depends
upon the vehicle speed, load, and the steepness of the
hills. When going up steep hills, you might have to step
on the accelerator pedal to maintain the vehicle’s speed.
When going downhill, you might have to brake or shift to
a lower gear to keep the vehicle’s speed down. Applying
the brake or shifting into a lower gear ends cruise control.
If you need to apply the brake or shift to a lower gear due
to the grade of the downhill slope, you might not want to
attempt to use the cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the cancel button on the steering wheel.
