2008 CADILLAC CTS engine

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 on page 4-30for 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 PARK (P), ignition must be in the
ON/RUN or ACC/ACCESSORY and the regular brake
pedal must be applied.
2-32

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 your 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 PARK (P), 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.
Key In the Ignition
Never leave your vehicle with the keys inside, as it is
an easy target for joy riders or thieves. A chime sounds
when the driver’s door is opened while the vehicle is
parked and the key is left in the ignition. Always
remember to remove the key from the ignition and take
it with you. This will lock the ignition and transmission.
Also, always remember to lock the doors.
The battery could be drained if the key is left in the
ignition while your vehicle is parked. The vehicle might
not start after it has been parked for an extended
period of time.
2-33

Ignition Positions (Keyless Access)
You can turn the ignition control knob to four different
positions.
To shift out of PARK (P), 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 PARK (P),
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’s 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 PARK (P) or NEUTRAL (N).
The engine will not start in any other position -- this
is a safety feature. To restart when you are already
moving, use NEUTRAL (N) only.If your 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 3-56for
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 2-10for more information.
Notice:Do not try to shift to P (Park) if your
vehicle is moving. If you do, you could damage
the transmission. Shift to P (Park) only when your
vehicle is stopped.
2-35

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. Your vehicle will
not start if the clutch pedal is not all the way down.
That is a safety feature.
Starting Procedure
1. With your foot off the accelerator pedal, turn the
ignition key to START. If your 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.
Your 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 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, 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
The engine coolant heater, if available, can help 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 in the engine compartment
on the passenger side of the vehicle in front of
the fuse block.
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.
How long should you keep the coolant heater plugged
in? The answer depends on the outside temperature, the
kind of oil you have, and some other things. Instead of
trying to list everything here, we ask that you contact your
dealer/retailer in the area where you will be parking your
vehicle. The dealer/retailer can give you the best advice
for that 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
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 (Automatic
Transmission) on page 2-45. If you are pulling
a trailer, seeTowing a Trailer on page 4-30.
2-38

Make sure the shift lever is fully in P (Park) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system. You must fully
apply your 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 2-47.
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.
R (Reverse):Use this gear to back up.
At low vehicle speeds, you can also use R (Reverse)
to rock your vehicle back and forth to get out of
snow, ice, or sand without damaging your transmission.
SeeIf Your Vehicle is Stuck in Sand, Mud, Ice, or
Snow on page 4-21for additional information.N (Neutral):In this position, the engine does not
connect with the wheels. To restart when you are
already moving, use N (Neutral) only. You can also
use N (Neutral) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while the engine is
running at high speed is dangerous. Unless
your foot is rmly 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.
