2005 CADILLAC XLR manual transmission

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, briey move the shift lever up
toward the plus symbol. To request a downshift, briey
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 3-34.
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 specic gear. The actual
gear the vehicle will choose depends on a combination
of the driver-requested gear range, vehicle speed
and throttle position.
Notice:If you drive your vehicle at high rpms
without upshifting while using Driver Shift Control
(DSC), you could damage your vehicle. Always
upshift when necessary while using DSC.
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.
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.
2-27

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).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 on, the parking brake indicator light
on the instrument panel cluster should come on.
If it does not, you need to have your vehicle serviced.

Automatic Transmission Fluid
How to Check
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to your dealer
service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is difficult,
you should have this done at your dealer service
department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 8-12.
Notice:Use of automatic transmission uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and the
damages may not be covered by your warranty.
Always use automatic transmission uid labeled
DEXRON
®-III, Approved for the H-Specication.Change both the uid and lter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
High performance operation.
If you do not use your vehicle under one of these
conditions, change the uid and lter every
100,000 miles (166 000 km).
SeeScheduled Maintenance on page 7-4for the proper
service intervals for the transmission uid and lter.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if you add only
DEX-COOL
®extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
on page 6-23.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice:If you try to start your vehicle by pushing
or pulling it, you could damage your vehicle. Do not
push or pull your vehicle to start it; instead, use
the jump starting procedure in this manual to start
your vehicle when the battery has run down.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
Notice:If you leave your radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered
by your warranty. Always turn off your radio and
other accessories when jump starting your vehicle.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn off
the radio and all lamps that are not needed. This
will avoid sparks and help save both batteries. And
it could save the radio!
