brakes CADILLAC XLR 2004 1.G Owners Manual

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.

This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference, and
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modi®cations to this system by other than
an authorized service facility could void authorization to
use this equipment.
Adaptive Cruise Control (ACC) is an enhancement to
traditional cruise control and is not a safety system. ACC
allows you to keep cruise control engaged in moderate
traffic conditions without having to constantly reset
your cruise control. ACC 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,
ACC can apply limited braking or acceleration of
the vehicle automatically to maintain a selected follow
distance to the vehicle ahead. ACC braking is limited to
0.3 g's (2.95 m/sec2) of deceleration, which is
comparable to moderate application of the vehicle's
brakes. To disengage ACC, apply the brake. If there is
no vehicle in your path, your vehicle will react like
traditional cruise control.
{CAUTION:
ACC will not apply hard braking or bring the
vehicle to a complete stop. ACC will not
respond to stopped vehicles, pedestrians or
animals. When you are approaching a vehicle
or object, ACC may not have time to slow your
vehicle enough to avoid a collision. Your
complete attention is always required while
driving and you should be ready to take action
and apply the brakes. For more information,
see
Defensive Driving on page 4-2.
3-10

Once ACC is set, it may immediately apply the brakes if
it detects a vehicle ahead is too close or moving
slower than your vehicle.
This symbol will appear on
the Head-Up Display
(HUD) to indicate that ACC
is active. See
Head-Up
Display (HUD) on
page 3-27
for more
information.
Make sure the set speed is visible on the HUD so you
know the speed your vehicle will accelerate to if no
vehicle is detected in your path. Keep in mind speed
limits, surrounding traffic speeds and weather conditions
when adjusting your set speed.
Increasing Set Speed While Using ACC
There are two ways to increase set speed:
·Use the accelerator to get to the higher speed.
Press the set button at the end of the lever,
then release the button and the accelerator pedal.
You will now cruise at the higher speed.
·Move the ACC switch from on to resume/increase.
Hold it there until the desired set speed is displayed
in the HUD, then release the switch. To increase
your set speed in very small amounts, move
the switch brie¯y to resume/increase. Each time
you do this, your vehicle set speed will increase by
1 mph (1.6 km/h). Your vehicle will not reach the
set speed until ACC determines there is no vehicle
in front of you. At that point, your vehicle speed
will increase to the set speed.
Decreasing Set Speed While Using ACC
Press in the set/decrease button on the end of the lever
until you reach the lower speed you want, then
release it.
To slow down in very small amounts, brie¯y press the
set/decrease button. Each time you do this, your
set speed will be 1 mph (1.6 km/h) slower.
Resuming a Set Speed
Suppose you set your ACC at a desired speed and then
you apply the brake. This will disengage the ACC.
But you do not need to reset it.
Once you are going about 25 mph (40 km/h) or more,
you can move the ACC switch brie¯y from on to
resume/increase. ACC will be engaged with the
previously chosen set speed.
3-13

Alerting the Driver
The alert symbol will ¯ash
on the HUD and a warning
beep will sound when
driver action is required.
Driver action is required when:
·ACC cannot apply sufficient braking because you
are approaching a vehicle too rapidly.
·The vehicle speed drops below about
20 mph (32 km/h).
·A temporary condition prohibits ACC from operating.
See
DIC Warnings and Messages on page 3-57for
more information.
·A malfunction is detected in the ACC system. See
DIC Warnings and Messages on page 3-57for
more information.
See
Defensive Driving on page 4-2for more information.
{CAUTION:
Adaptive Cruise Control has only limited
braking ability to slow your vehicle. In some
cases, ACC may not have time to slow your
vehicle enough to avoid a collision. Be ready
to take action and apply the brakes yourself.
See
Defensive Driving on page 4-2.
3-15

Approaching and Following a Vehicle
The vehicle ahead symbol
will only appear on the
HUD when a vehicle ahead
is detected in your path.
If this symbol does not appear, or disappears brie¯y,
ACC will not respond to vehicles you may see ahead.{CAUTION:
When the ACC radar is blocked by snow, ice,
or dirt, it may not detect a vehicle ahead until
it is very close. ACC may not have time to
slow your vehicle enough to avoid a collision.
Do not use ACC when the radar is blocked by
snow, ice, or dirt. Keep your radar clean. See
ªCleaning the Systemº later in this section.
ACC will automatically slow your vehicle down when
approaching a slower moving vehicle. ACC will
then adjust your speed to follow the vehicle in front at
the selected follow distance. Your speed will increase or
decrease to follow the vehicle in front of you but will
never exceed the set speed. ACC may apply limited
braking if necessary. When braking is active, your brake
lights will come on. It may feel or sound different than
if you were applying the brakes yourself. This is normal.
3-16

Stationary or Very Slow-Moving Objects
{CAUTION:
ACC may not detect and react to stationary or
slow-moving objects in your lane. You could
crash into an object ahead of you. Do not use
ACC when approaching stationary or
slow-moving vehicles or other objects.
{CAUTION:
ACC may not detect and react to stationary or
slow-moving objects in your lane. ACC may
accelerate toward objects, such as a stopped
vehicle that suddenly appears after the lead
vehicle changes lanes. Your complete attention
is always required while driving and you
should be ready to take action and apply the
brakes.
Low-Speed Deactivation
If your speed falls below 20 mph (32 km/h) while
following a vehicle ahead, ACC will begin to disengage.
The driver alert symbol on the HUD will ¯ash and the
warning beep will sound. The driver must take
action since ACC will not slow the vehicle to a stop.
Passing a Vehicle
If you need to increase speed to pass a vehicle, use the
accelerator pedal. While your foot is on the accelerator
pedal, the system will not automatically apply the
brakes. Once you pass the vehicle and remove your
foot from the accelerator pedal, ACC will return to
normal operation and be able to apply the brakes if
needed.
{CAUTION:
If you rest your foot on the accelerator pedal,
the system will not automatically apply the
brakes. You could crash into a vehicle ahead
of you. Do not rest your foot on the accelerator
pedal when using ACC.
3-17

Curves in the Road
{CAUTION:
Due to ACC limitations in curves, it may
respond to a vehicle in another lane, or may
not have time to react to a vehicle in your lane.
You could crash into a vehicle ahead of you,
or lose control of your vehicle. Give extra
attention in curves and be ready to use the
brakes if necessary. Select an appropriate
speed while driving in curves.
ACC may operate differently in a sharp curve.
ACC may reduce your speed in a curve if the curve is
too sharp. The TIGHT CURVE message will also display
on the HUD. See
Head-Up Display (HUD) on page 3-27for more information.When following a vehicle and entering a curve, ACC
could lose track of the vehicle in your lane and
accelerate your vehicle. When this happens, the vehicle
ahead symbol will not appear on the HUD.
3-18

ACC may detect a vehicle that is not in your lane and
apply the brakes.
ACC may occasionally provide a driver alert and/or
braking that you consider unnecessary. ACC could
respond to signs, guardrails and other stationary objects
when entering or exiting a curve. This is normal
operation. Your vehicle does not need service.
Highway Exit Ramps
{CAUTION:
ACC may lose track of the vehicle ahead and
accelerate up to your set speed while entering
or on highway exit ramps. You could be
startled by this acceleration and even lose
control of the vehicle. So, disengage ACC
before entering a highway exit ramp. Do not
use ACC on exit ramps.
3-19

Other Vehicle Lane Changes
If another vehicle enters the same lane as you, ACC will
not detect the vehicle until it is completely in the lane.
Be ready to take action and apply the brakes yourself.
Using ACC on Hills
How well ACC will work on hills depends on your
speed, vehicle load, traffic conditions and the steepness
of the hills. ACC may not detect a vehicle in your
lane while driving on hills. When going up steep hills,
you may want to use the accelerator pedal to maintain
your speed. When going downhill, you may have to
brake to keep your speed down. Applying the brake
disengages ACC. Many drivers ®nd this to be too much
trouble and do not use ACC on steep hills.
3-20

How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R) and the vehicle speed is less
than 3 mph (5 km/h). When the system comes on,
the three lights on the display will illuminate to let you
know that the system is working. URPA senses
how close your vehicle is to an object. The distance is
determined by the four ultrasonic sensors located on the
rear bumper. When you shift into REVERSE (R) and
an object is detected, the following will occur in
sequence depending on the distance from the object:
·At 5 feet (1.5 m) a chime will sound and one
amber light will be lit;
·at 40 inches (1.0 m) both amber lights will be lit;
·at 20 inches (0.5 m) a continuous chime will
sound and all three lights (amber/amber/red) will be
lit; and
·at 1 foot (0.3 m) a continuous chime will sound and
all three lights (amber/amber/red) will ¯ash.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the
rear sensors to recognize an object, it must be within
operating range.If the URPA system is not functioning properly, the
display will ¯ash red, indicating that there is a problem.
The light will also ¯ash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to ¯ash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h).
It may also ¯ash red if the ultrasonic sensors are not
kept clean. So be sure to keep your rear bumper free of
mud, dirt, snow, ice and slush or materials such as
paint or the system may not work properly. If after
cleaning the rear bumper and driving forward at least
15 mph (25 km/h), the display continues to ¯ash red, see
your dealer. For cleaning instructions, see
Cleaning
the Outside of Your Vehicle on page 5-78.
It may also ¯ash red if your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h).
Other conditions that may affect system performance
include things like the vibrations from a jackhammer or
the compression of air brakes on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots.
