2009 CADILLAC XLR cruise control

Not all manual downshift requests will be allowed by
the transmission. To prevent excessive engine RPMs,
each gear has a maximum vehicle speed associated
with it. Any downshift request above this speed is
not allowed by the transmission.
If shifting is prevented for any reason, the current
gear ashes multiple times in the Driver Information
Center (DIC), indicating that the transmission has
not shifted gears.
Some automatic downshifts can occur to maintain
minimum engine speed. This only happens if the vehicle
is left in too high of a gear for the vehicle’s speed.
For example, if you have been driving in sixth gear range
and come to a stop without manually downshifting, the
transmission automatically downshifts to rst gear and
displays rst gear on the HUD. As you begin to drive and
accelerate, the transmission remains in rst gear until the
driver selects an upshift.DSC can be used while using cruise control, but
transmission shifting is different while the cruise control
is on. This is not a malfunction and is necessary to
let proper operation of the cruise control.
To return to fully automatic operation, move the shift
lever to the right and back into D (Drive).
When accelerating the vehicle from a stop in snowy and
icy conditions, you may want to shift into second gear.
A higher gear allows you to gain more traction on slippery
surfaces.
In higher gears, on the XLR only, an automatic downshift
occurs if you press the accelerator pedal to the oor.
This feature provides adequate acceleration capabilities
if you forget to downshift manually. Tap the shifter
forward and the vehicle upshifts.

Heated Steering Wheel
For vehicles with a heated steering wheel, the button for
this feature is located on the steering wheel.
(:Press to turn the heated steering wheel on or off.
A light on the button displays when the feature is
turned on.
The steering wheel takes about three minutes to start
heating.
Turn Signal/Multifunction Lever
The lever on the left side of the steering column
includes the following:
G: Turn and Lane-Change Signals
3: Headlamp High/Low-Beam Changer

I: Cruise Control
P: Exterior Lamps Control
Flash-to-Pass Feature. SeeFlash-to-Pass on
page 3-8.
Information for these features is on the pages following.
Turn and Lane-Change Signals
An arrow on the instrument
panel cluster ashes in the
direction of the turn or
lane change.
Move the multifunction lever all the way up or down to
signal a turn.
Raise or lower the lever until the arrow starts to ash to
signal a lane change. Hold it there until the lane
change is complete.
The lever returns to its starting position whenever it is
released.

Headlamp Washer
The headlamps washer only functions every fourth time
the washer button is pressed and if the headlamps
are on.
Cruise Control
With cruise control, a speed of about 25 mph (40 km/h)
or more can be maintained without keeping your foot
on the accelerator. Cruise control does not work
at speeds below about 25 mph (40 km/h).
Cruise control will not work if the parking brake is set, or
if the master cylinder brake uid level is low.
{CAUTION:
Cruise control can be dangerous where you cannot
drive safely at a steady speed. So, do not use the
cruise control on winding roads or in heavy traffic.
Cruise control can be dangerous on slippery roads.
On such roads, fast changes in tire traction can
cause excessive wheel slip, and you could lose
control. Do not use cruise control on slippery roads.If the vehicle has the traction control system and it
begins to limit wheel spin while cruise control is on,
the cruise control will automatically disengage.
SeeTraction Control System (TCS) on page 5-8.
When road conditions allow cruise control to be safely
used again, it can be turned back on.9(Off):Turns the system off.
R(On):Turns the system on.
+ (Resume/Accelerate):Makes the vehicle accelerate
or resume to a previously set speed.
T(Set):Press this button at the end of the lever to
set the speed.

Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you are
not using cruise, you might hit a button and go
into cruise when you do not want to. You could be
startled and even lose control. Keep the cruise
control switch off until you want to use cruise
control.
1. Move the cruise control switch to on.
2. Get up to the speed desired.
3. Press the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
This light
Jappears on the instrument panel cluster
when the cruise control is engaged.
Resuming a Set Speed
If the cruise control is set at a desired speed and
the brake is applied, the cruise control will turn off.
It does not need to be reset
Once the vehicle is going about 25 mph (40 km/h) or
more, move the cruise control switch briey from
RtoS.
The vehicle will go back up to the chosen speed and
stay there.
If the switch is held at resume/accelerate the vehicle
will keep going faster until the switch is released or
the brake is applied. Do not hold the switch at
resume/accelerate, unless you want the vehicle to
go faster.

Increasing Speed While Using Cruise
Control
There are two ways to increase speed:
Use the accelerator pedal to get to the higher
speed. Press
Tat the end of the lever, then
release the button and the accelerator pedal.
The vehicle will now cruise at the higher speed.
If the accelerator pedal is held longer than
60 seconds, cruise control will turn off.
Move the cruise switch fromRtoS. Hold it there
until the desired speed is reached, and then
release the switch. To increase the vehicle speed
in small amounts, move the switch briey to
resume/accelerate. Each time this is done, the
vehicle goes about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control

Press and hold the set button until the lower speed
desired is reached, then release it.
To slow down in small amounts, briey press the
set button. Each time this is done, the vehicle
goes about 1 mph (1.6 km/h) slower.
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 cruise control speed set earlier.
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 your speed.
When going downhill, you might have to brake or shift
to a lower gear to keep your vehicle’s speed down.
When the brakes are applied the cruise control turns off.
Ending Cruise Control
There are two ways to turn off the cruise control:
Step lightly on the brake pedal
Move the cruise control switch to9
Erasing Speed Memory
The cruise control set speed memory is erased when
the cruise control or the ignition is turned off.

Adaptive Cruise Control
If the vehicle has this feature, be sure to read this entire
section before using it.
The system operates on a radio frequency subject to
Federal Communications Commission (FCC) Rules and
with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control is an enhancement to traditional
cruise control and is not a safety system. It allows
you to keep cruise control engaged in moderate traffic
conditions without it having to be constantly reset.
Adaptive Cruise Control uses radar to detect a vehicle
directly ahead in your path, within a distance of
328 ft (100 m), and operates at speeds above
25 mph (40 km/h). When it is engaged by the driver,
the system can apply limited braking or acceleration
of the vehicle, automatically, to maintain a selected
following distance to the vehicle ahead. The vehicle’s
braking during Adaptive Cruise Control is comparable to
a person applying moderate pressure to the vehicle’s
brake pedal. To disengage Adaptive Cruise Control,
apply the brake. If no vehicle is in your path, your
vehicle will react like traditional cruise control.
