2009 CADILLAC XLR brake

When following a vehicle and entering a curve, Adaptive
Cruise Control 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.Adaptive Cruise Control might detect a vehicle that is
not in your lane and apply the brakes.
Adaptive Cruise Control might occasionally provide
a driver alert and/or braking that you consider
unnecessary. It 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:
Adaptive Cruise Control 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. Disengage Adaptive Cruise
Control before entering a highway exit ramp. Do not
use Adaptive Cruise Control while entering or on
exit ramps.
Other Vehicle Lane Changes
If another vehicle enters the same lane as you, Adaptive
Cruise Control will not detect the vehicle until it is
completely in the lane. Be ready to take action and apply
the brakes yourself.
Using Adaptive Cruise Controls on Hills
How well Adaptive Cruise Control works on hills
depends on your speed, vehicle load, traffic conditions,
and the steepness of the hills. It might not detect a
vehicle in your lane while driving on hills. While going
up steep hills, you might want to use the accelerator
pedal to maintain your vehicle speed. While going
downhill, you might have to brake to keep your vehicle
speed down. Applying the brake disengages the
system. You may choose not to use Adaptive Cruise
Control on steep hills.
Disengaging Adaptive Cruise Control
Apply the brake pedal or move the Adaptive Cruise
Control switch to off, to disengage the system. Adaptive
Cruise Control information does not appear on the
HUD while the system is not engaged.

Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking,
though, both parts need to be working well.
This light should come on when the engine is started.
If it does not come on then, have it xed so it will
be ready to warn if there is a problem.
If this warning light stays on after the engine is started,
the parking brake may still be set or there could be
a brake problem. Refer toParking Brake on page 2-32
to see if it is set. If the parking brake is not set, have
the brake system inspected right away.If the light comes on while driving and a LOW BRAKE
FLUID message is showing on the DIC, pull off the road
and stop carefully. The pedal may be harder to push.
Or, the pedal may go closer to the oor and it may take
longer to stop. If the light is still on, have the vehicle
towed for service. SeeTowing Your Vehicle on
page 5-26.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service. United States
