2008 CADILLAC XLR cruise control

Curves in the Road
{CAUTION:
Due to Adaptive Cruise Control 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.
Adaptive Cruise Control might operate differently in a
sharp curve. It might reduce your speed if the curve is
too sharp. The TIGHT CURVE message will also display
on the HUD. SeeHead-Up Display (HUD) on page 3-33
for more information.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.
3-24

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.
3-25

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.
3-26

Erasing Set Speed Memory
The set speed memory is erased when the Adaptive
Cruise Control switch or the ignition is turned off.
Other Messages
There are three messages that may appear on the DIC.
They are SERVICE RADAR CRUISE, CRUISE NOT
READY and CLEAN RADAR CRUISE. These messages
will only appear to indicate a problem with the Adaptive
Cruise Control. SeeDIC Warnings and Messages
on page 3-63for more information.
You may also see CRUISE SPEED LIMITED displayed
in the HUD. SeeHead-Up Display (HUD) on page 3-33
for more information.
Cleaning the System
The radar can become blocked by snow, ice, or dirt.
If so, you may need to turn off the engine and clean the
lens, located on the driver’s side of the front fascia.Clean the surface with a 50/50 mixture of isopropyl
alcohol and water on a dampened cloth. After cleaning
the fascia lens, try to engage Adaptive Cruise Control.
If this does not x the problem, you may have to remove
the fascia lens and clean the inside of the fascia lens
and radar lens.
To clean the inside of the fascia lens and radar lens,
insert a tool into one of the small slots on the inboard
side of the lens and pop the lens out. Clean the surface
with a 50/50 mixture of isopropyl alcohol and water
on a dampened cloth. After cleaning the lens, set the
lens back in place and press until it snaps in place.

Battery Run-Down Protection
Your vehicle has a feature to help prevent the battery
from being drained, in case the underhood lamp, vanity
mirror lamps, cargo lamps, reading lamps, console, or
glove box lamps are accidentally left on, or something is
left plugged into the accessory power outlet or cigarette
lighter. If any of the accessory lamps are left on, they will
automatically time-out after about 10 minutes. To reset
the battery protection, all of the above lamps must be
turned off or the ignition must be in the Acc. position.
Head-Up Display (HUD)

outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
The Head-Up Display (HUD) allows you to see some of
the driver information that appears on your instrument
panel cluster.The information may be displayed in English or metric

The following Adaptive Cruise Control (ACC) messages
may appear in the HUD:
CRUISE SPEED LIMITED:This message indicates that
your vehicle speed has been reduced below your set
speed due to ACC limitations. Your set speed is too high
and ACC cannot detect other vehicles at far enough
distances for the system to operate properly.
TIGHT CURVE:This message indicates that ACC has
reduced your vehicle speed due to a tight curve in
the road. Once the road straightens, ACC will return to
your selected set speed or follow distance setting.
See “Adaptive Cruise Control (ACC)” underTurn
Signal/Multifunction Lever on page 3-8for more
information.
You may also see an ACC active symbol, alert symbol
or vehicle ahead symbol. See “Adaptive Cruise

on page 3-8for more information.Accessory Power Outlet(s)
The accessory power outlet can be used to connect
electrical equipment such as a cellular phone or
CB radio.
The accessory power outlet is located inside the
center console storage compartment, on the forward
left side.
To use the outlet, remove the tethered cap. When not
using it, always cover the outlet with the protective cap.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 20 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your vehicle’s battery.
Certain electrical accessories may not be compatible
