engine CADILLAC XLR 2004 1.G User Guide

Notice:Holding the button in for longer than
15 seconds at a time will cause the battery to be
drained much sooner. This can also cause damage
to the starter motor. Wait 15 seconds between
each try to avoid draining your vehicle's battery or
damaging the starter.
2. If the engine does not start and no DIC message is
displayed, wait 15 seconds before trying again.
Notice:Your engine is designed to work with the
electronics in your 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, your engine
might not perform properly.
Stopping Your Engine
Move the shift lever to PARK (P) and press the
OFF/ACCESSORY button. If the shifter is not in PARK
(P), the vehicle will go into ACCESSORY mode and
the DIC will display SHIFT TO PARK. Once the shifter
is moved to PARK (P), the vehicle will turn off.If the keyless access transmitter is not detected
while going to off, the DIC will display NO FOB, OFF
OR RUN.
See
DIC Warnings and Messages on page 3-57for
more information.
Engine Coolant Heater
Your vehicle may be equipped with an engine coolant
heater.
In very cold weather, 0ÉF (-18ÉC) or colder, the engine
coolant heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged in a
minimum of four hours prior to starting your vehicle. At
temperatures above 32ÉF (0ÉC), use of the coolant
heater is not required.
2-21

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's side
of the engine compartment, in front of the engine
coolant surge tank.
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 in the area where you will be parking
your vehicle. The dealer can give you the best advice
for that particular area.

Automatic Transmission Operation
There are several different positions for your shift lever.
PARK (P):This position locks your rear wheels. It is
the best position to use when you start your engine
because your vehicle cannot move easily.
{CAUTION:
It is 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 your
parking brake and move the shift lever to
PARK (P). See
Shifting Into Park (P) on
page 2-28
.
Be sure the shift lever is fully in PARK (P) before
starting the engine. Your vehicle has an automatic
transmission shift lock control system.
2-23

You have to fully apply your regular brakes before you
can shift from PARK (P) when the vehicle is running.
If you cannot shift out of PARK (P), ease pressure
on the shift lever and push the shift lever all the way
into PARK (P) as you maintain brake application. Then
move the shift lever into the gear you wish. See
Shifting Out of Park (P) on page 2-30.
REVERSE (R):Use this gear to back up.
Notice:Shifting to REVERSE (R) while your vehicle
is moving forward could damage the transmission.
The repairs would not be covered by your warranty.
Shift to REVERSE (R) only after your vehicle is
stopped.
To rock your vehicle back and forth to get out of snow,
ice or sand without damaging your transmission,
see If You Are Stuck: In Sand, Mud, Ice or Snow on
page 4-31.
NEUTRAL (N):In this position, your engine does not
connect with the wheels. To restart when you are
already moving, use NEUTRAL (N) only. Also, use
NEUTRAL (N) when your vehicle is being towed.
{CAUTION:
Shifting into a drive gear while your engine is
running at high speed is dangerous. Unless
your foot is ®rmly on the brake pedal, your
vehicle could move very rapidly. You could
lose control and hit people or objects. Do not
shift into a drive gear while your engine is
running at high speed.
Notice:Shifting out of PARK (P) or NEUTRAL (N)
with the engine running at high speed may damage
the transmission. The repairs would not be
covered by your warranty. Be sure the engine is not
running at high speed when shifting your vehicle.
AUTOMATIC OVERDRIVE (D):This position is
for normal driving.
Notice:Spinning the tires or holding the vehicle in
one place on a hill using only the accelerator
pedal may damage the transmission. If you are
stuck, do not spin the tires. When stopping on a hill,
use the brakes to hold the vehicle in place.
Maximum engine speed is limited to protect driveline
components from improper operation.
2-24

Driver Shift Control
The driver shift control feature gives you more manual
control over the operation of the transmission.
To use this feature, move
the shift lever from the
AUTOMATIC OVERDRIVE
(D) position to the left
and into the driver
shift control gate.
A plus symbol will also appear on the shift console
above the AUTOMATIC OVERDRIVE (D) indicator and
minus symbol will appear below the indicator.
To request an upshift, brie¯y move the shift lever up
toward the plus symbol. To request a downshift, brie¯y
move the shift lever down toward the minus symbol.
The Head-Up Display (HUD) will display the change in
gear range, though the actual upshift or downshift
may be delayed until the engine speed is correct for the
requested gear range.The currently selected gear will be remembered as the
selected gear range and will be displayed in the
HUD. SeeHead-Up Display (HUD) on page 3-27.
The gear range indicated in the HUD is only a requested
range of available gears. It does not indicate that the
vehicle will operate only in that speci®c gear. The actual
gear the vehicle will choose depends on a combination
of the driver-requested gear range, vehicle speed
and throttle position.
If you do not upshift as the engine approaches the
redline engine rpm for the selected gear range,
an engine speed limiter will prevent over-revving by
limiting the engine rpm available. No automatic upshift
will occur until you request it. Operating the engine
for extended periods of time against the speed limiter is
not recommended.
Not all manual downshift requests will be accepted by
the transmission. To prevent over-revving the engine,
each gear range has a maximum vehicle speed
associated with it. Any downshift request above this
speed will be ignored by the transmission.
2-25

Some automatic downshifts may occur to maintain
minimum engine speed. This will only occur if you leave
the vehicle in too high of a gear range for the speed
the vehicle is traveling. For example, if you have been
driving in ®fth gear range and come to a stop without
manually downshifting, ®fth gear range will continue to
display in the HUD. The transmission will automatically
downshift to second gear. As you begin to drive
and accelerate, the transmission will automatically
upshift as quickly as possible to the selected ®fth
gear range.
In higher gear ranges, an automatic downshift will occur
if you press the accelerator pedal to the ¯oor. This
feature provides you with adequate acceleration
capabilities if you forget to downshift manually.
Automatic upshifts and downshifts will not display in
the HUD.
Driver shift control is available while the cruise control is
engaged. The shift behavior of the transmission will
react differently than when cruise control is not engaged.
This is not a malfunction and is necessary to allow
proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into the AUTOMATIC
OVERDRIVE (D) position.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 running, the parking brake indicator light
on the instrument panel cluster should come on. If it
does not, you need to have your vehicle serviced.
2-26

When you move out of PARK (P) or NEUTRAL (N) and
the engine is running, the parking brake should
release. If the parking brake has not been fully released
and you try to drive off with the parking brake on, the
parking brake indicator light will come on and stay on.
If the parking brake does not fully release, you can
manually release the pedal. However, be sure to read
the following paragraphs:
{CAUTION:
Always shift to PARK (P) before pulling the
manual release lever. If your hand or arm is in
the way of the pedal you could be hurt. The
pedal springs back quickly. Keep your hand
and arm away when you use the manual
release lever.
Before releasing the manual parking brake, be sure to
put the vehicle in PARK (P) and turn the ignition off.Reach under the driver's side of the instrument panel
and pull down on the manual release lever, which
is located behind the parking brake pedal. Pull down on
the yellow tab as shown by the arrow in the illustration.
If the parking brake does not release, you should
have your vehicle towed to your dealer for service.
Notice:Driving with the parking brake on can
overheat the brake system and cause premature
wear or damage to brake system parts. Verify that
the parking brake is fully released and the brake
warning light is off before driving.
2-27

Shifting Into Park (P)
{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.
1. Hold the brake pedal down with your right foot and
set the parking brake.2. Move the shift lever
into PARK (P) by
pushing the lever all
the way toward
the front of the vehicle.
3. Turn the ignition off.
2-28

Leaving Your Vehicle With the Engine
Running
{CAUTION:
It can be dangerous to leave your vehicle with
the engine running. Your vehicle could move
suddenly if the shift lever is not fully in
PARK (P) with the parking brake ®rmly set.
And, if you leave the vehicle with the engine
running, it could overheat and even catch ®re.
You or others could be injured. Do not leave
your vehicle with the engine running.
If you have to leave your vehicle with the engine
running, be sure your vehicle is in PARK (P) and your
parking brake is ®rmly set before you leave it. After you
have moved the shift lever into PARK (P), hold down
the regular brake pedal. See if you can move the
shift lever away from PARK (P) without ®rst pulling it
toward you. If you can, it means that the shift lever was
not fully locked into PARK (P).
Torque Lock
If you are parking on a hill and you do not shift your
transmission into PARK (P) properly, the weight of the
vehicle may put too much force on the parking pawl
in the transmission. You may ®nd it difficult to pull the
shift lever out of PARK (P). This is called ªtorque
lock.º To prevent torque lock, set the parking brake and
then shift into PARK (P) properly before you leave
the driver's seat. To ®nd out how, see ªShifting
Into PARK (P)º listed previously in this section.
When you are ready to drive, move the shift lever out of
PARK (P) before you release the parking brake.
If torque lock does occur, you may need to have another
vehicle push yours a little uphill to take some of the
pressure from the parking pawl in the transmission, so
you can pull the shift lever out of PARK (P).
2-29

Shifting Out of Park (P)
Your vehicle has an automatic transmission shift lock
control system. You have to fully apply your regular
brake before you can shift from PARK (P) when
the vehicle is running. See
Automatic Transmission
Operation on page 2-23.
If you cannot shift out of PARK (P), ease pressure on
the shift lever ± push the shift lever all the way into
PARK (P) and release the shift lever button as
you maintain brake application. Then press the shift
lever button and move the shift lever into the gear
you wish.If you ever hold the brake pedal down but still cannot
shift out of PARK (P), try this:
1. Press the ACCESSORY button twice to place the
ignition in accessory mode.
2. Apply and hold the brake until the end of Step 4.
3. Shift to NEUTRAL (N).
4. Start the engine and then shift to the drive gear
you want.
5. Have your vehicle inspected by your dealer as soon
as possible.
