2009 CADILLAC CTS engine

Immobilizer Operation
(Keyless Access)
Your vehicle has a passive theft-deterrent system.
The system is automatically armed when the ignition
control knob is turned to LOCK/OFF.
The immobilization system is disarmed when the ignition
control knob is pushed in and a valid transmitter is
found in the vehicle.
You do not have to manually arm or disarm the system.
The security light will come on if there is a problem
with arming or disarming the theft-deterrent system.
The system has one or more keyless access transmitters
that are matched to an immobilizer control unit in your
vehicle. Only a correctly matched keyless access
transmitter will start the vehicle. If the keyless access
transmitter is ever damaged, you may not be able to
start your vehicle.
When trying to start the vehicle, if the engine does not
start and the security light comes on, there may be a
problem with your immobilizer system. Turn the ignition
control knob off and try again.If the ignition control knob does not rotate, and the
keyless access transmitter appears to be undamaged,
try another keyless access transmitter. Or, you may
try placing the transmitter in the transmitter pocket
located in the center console. See “Electronic Key Not
Detected” underDIC Warnings and Messages on
page 3-58. At this time, you may also want to check the
fuse. SeeFuses and Circuit Breakers on page 5-115.
If the ignition control knob still does not rotate with
the other transmitter, your vehicle needs service. If the
ignition control knob does rotate, the rst transmitter
may be faulty. See your dealer/retailer who can service
the theft-deterrent system and have a new keyless
access transmitter programmed to the vehicle.
It is possible for the immobilizer system to learn new or
replacement keyless access transmitters. Up to 4 keyless
access transmitters can be programmed for the vehicle.
To program additional transmitters, see “Matching
transmitter(s) to Your Vehicle” underKeyless Access
System Operation on page 2-8.
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 for the rst 500 miles
(805 km):
Do not drive at any one constant speed, fast
or slow.
Do not exceed 70 mph (113 km/h).
Do not make full-throttle starts; also refrain
from using the full throttle while driving.
Avoid downshifting to brake or slow the vehicle.If these procedures are not followed, the engine,
axle, or other parts could be damaged.
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 break-in guideline every
time you get new linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer (CTS-V) on page 4-27orTowing a Trailer
(CTS) on page 4-28for the trailer towing capabilities
of your vehicle and more information.
Following break-in, engine speed and load can be
gradually increased.

Ignition Positions (Key Access)
The key can be turned to four different positions.
To shift out of P (Park), the ignition must be in the
ON/RUN or ACC/ACCESSORY and the brake pedal
must be applied.
Notice:Using a tool to force the key from its
cylinder could cause damage or break the key. Use
the correct key and turn the key only with your hand.
Make sure the key is all the way in. If it is and you
have a manual transmission vehicle, turn the steering
wheel left and right while you turn the key hard. If
none of this works, then the vehicle needs service.A (LOCK/OFF):This is the only position in which the
key can be inserted or removed. This position locks the
ignition and shifter on automatic transmission vehicles,
and the ignition and steering wheel on manual
transmission vehicles.
B (ACC/ACCESSORY):This position lets you use
things like the radio and the windshield wipers when
the engine is off. This position allows you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the
position the ignition switch returns to after the engine
starts, and the key is released.
To shift the transmission out of P (Park), the ignition
key has to be in ACC/ACCESSORY or ON/RUN.
The battery could be drained if the key is left in the
ACC/ACCESSORY or ON/RUN position with the
engine off. The vehicle might not start if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine. When
the engine starts, release the key. The ignition switch
returns to ON/RUN for driving.
A warning tone will sound when the driver door is
opened, the ignition is in ACC/ACCESSORY or
LOCK/OFF and the key is in the ignition.

Ignition Positions (Keyless Access)
You can turn the ignition control knob to four different
positions.
To shift out of P (Park), ignition must be in the ON/RUN
or ACC/ACCESSORY and the regular brake pedal
must be applied.
Using a tool to force the ignition control knob from its
cylinder could damage it.
Make sure the keyless access transmitter is inside the
vehicle when trying to turn the ignition control knob.A (LOCK/OFF):The ignition control knob cannot be
removed from the vehicle. The keyless access
transmitter must be inside the vehicle to start the
engine. This position locks the ignition and shifter on
automatic transmission vehicles, and the ignition
and steering wheel on manual transmission vehicles.
B (ACC/ACCESSORY):This position allows you to use
things like the radio and the windshield wipers when
the engine is off. This position will allow you to turn off
the engine.
C (ON/RUN):This position is for driving. It is the position
the ignition switch returns to after the engine starts, and
the control knob is released.
If you need to shift the transmission out of P (Park), the
ignition control knob has to be in ACC/ACCESSORY or
ON/RUN.
The battery could be drained if you leave the key in the
ACC/ACCESSORY or ON/RUN position with the engine
off. You may not be able to start your vehicle if the battery
is allowed to drain for an extended period of time.
D (START):This position starts the engine.

Retained Accessory Power (RAP)
These vehicle accessories can be used for up to
10 minutes after the engine is turned off:
Audio System
Power Windows
Sunroof (if equipped)
Power to the audio system will work up to 10 minutes or
until the driver door is opened. Power to the windows or
sunroof will work up to 10 minutes or until any door is
opened. For an additional 10 minutes of operation, close
all the doors and turn the key to ON/RUN and then back
to LOCK/OFF.
Starting the Engine
Place the transmission in the proper gear.
Automatic Transmission
Move the shift lever to P (Park) or N (Neutral). The
engine will not start in any other position. To restart
the engine when the vehicle is already moving, use
N (Neutral) only.If the vehicle has the keyless access system, put your
foot on the brake pedal and turn the ignition control knob
to the START position. When the engine begins cranking,
let go of the ignition control knob, it will return to the
ON/RUN position.
If the transmitter is not in the vehicle or something is
interfering with the transmitter, the Driver Information
Center (DIC) will display Electronic Key Not Detected.
SeeDIC Warnings and Messages on page 3-58for
more information.
If the battery in the keyless access transmitter needs
replacing, the DIC displays Replace Battery In Remote
Key. The vehicle can still be driven. See “Battery
Replacement” underKeyless Access System Operation
on page 2-8for more information.
Notice:Do not try to shift to P (Park) if the
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when
the vehicle is stopped.Manual Transmission
The shift lever should be in neutral position and the
parking brake engaged. Hold the clutch pedal down to
the oor and start the engine. The vehicle will not start if
the clutch pedal is not all the way down.

Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. If the vehicle has the keyless
access system, make sure there is a keyless access
transmitter in the vehicle. When the engine starts,
let go of the ignition. The idle speed will go down
as your engine gets warm. Do not race the engine
immediately after starting it. Operate the engine and
transmission gently to allow the oil to warm up and
lubricate all moving parts.
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 for many seconds, 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 ACC/ACCESSORY or LOCK/OFF.
Notice:Cranking the engine for long periods of
time, by returning the key to the START position
immediately after cranking has ended, can overheatand 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, do the same thing. 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.

Engine Coolant Heater
Vehicles with the engine coolant heater can use this
option in cold weather conditions at or below 0°F (−18°C)
for easier starting and better fuel economy during engine
warm-up. Plug in the coolant heater at least four hours
before starting your vehicle. An internal thermostat in
the plug-end of the cord may exist which will prevent
engine coolant heater operation at temperatures
above 0°F (−18°C).
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located near the driver side strut
tower.
Remove the plastic cap to access the plug.
3. Plug it into a normal, grounded 110-volt AC outlet.
{CAUTION:
Plugging the cord into an ungrounded outlet could
cause an electrical shock. Also, the wrong kind of
extension cord could overheat and cause a re.
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. If you do not, it could be
damaged.
Contact your dealer/retailer for information on how
long to use the heater in your particular area.

Automatic Transmission Operation
The shift lever is located on the center console between
the front seats.
There are several different
positions for the shift lever.
P (Park):This position locks the rear 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 (Automatic
Transmission) on page 2-47. If you are pulling a
trailer, seeTowing a Trailer (CTS-V) on page 4-27
orTowing a Trailer (CTS) 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 must fully apply the regular
brakes rst and then press the shift lever button before
you can shift from P (Park) when the ignition key is in
ON/RUN. If you cannot shift out of P (Park), ease
pressure on the shift lever and push the shift lever all the
way into P (Park) as you maintain brake application. Then
press the shift lever button and move the shift lever into
another gear. SeeShifting Out of Park on page 2-48.
