2009 CADILLAC XLR instrument cluster

SERVICE ABS (Antilock Brake System)
If this message displays when you are driving, stop
as soon as possible and turn the ignition off. Then start
the engine again to reset the system. If the message
stays on, or comes back on again while you are driving,
the vehicle is in need of service. See your dealer/retailer.
If the SERVICE ABS message is being displayed, the
Traction Control System (TCS) and StabiliTrak
®System
will also be disabled. The Driver Information Center
will scroll three messages: SERVICE ABS, SERVICE
TRACTION SYS, and SERVICE STABILITRAK, and the
antilock brake system and traction control warning
lights on the instrument panel cluster will be illuminated.
SeeAntilock Brake System (ABS) Warning Light on
page 3-48andStabiliTrak
®/Traction Control System
(TCS) Warning Light on page 3-48. The driver can
acknowledge these messages by pressing the RESET
button three times. When the service message is
displayed, the computer controlled systems will not
assist the driver and you should have the system
repaired by your dealer/retailer as soon as possible.
Adjust your driving accordingly.
SERVICE AFS (Adaptive Forward
Lighting System) LAMPS
This message displays when the Adaptive Forward
Lighting System (AFS) is disabled and needs service.
See your dealer/retailer. SeeAdaptive Forward Lighting
System on page 3-28for more information.
SERVICE ELECT (Electrical) SYSTEM
This message displays if an electrical problem has
occurred within the Powertrain Control Module (PCM).
Have the vehicle serviced by your dealer/retailer.
SERVICE FUEL SYSTEM
This message displays when the Powertrain Control
Module (PCM) has detected a problem within the fuel
system. Have the vehicle serviced by your dealer/retailer.
This message will also be displayed when the cluster is
not getting fuel information from the PCM.

If the LOW COOLANT message does not appear on the
Driver Information Center (DIC) after two minutes, the
coolant is at the proper ll level. If a LOW COOLANT
message does appear, repeat Steps 1 through 3 then
reinstall the pressure cap, or see your dealer/retailer.
If coolant is needed, add the proper DEX-COOL
®
coolant mixture at the coolant surge tank.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may occur.
Be sure the cap is properly and tightly secured.
The coolant surge tank pressure cap must be fully
installed on the coolant surge tank. SeeEngine
Compartment Overview on page 6-12for more
information on location.
Engine Overheating
The vehicle has several indicators to warn of engine
overheating.
There is a COOLANT OVER TEMP message or an
ENGINE HOT, STOP ENGINE message displayed in the
Driver Information Center (DIC). SeeDIC Warnings
and Messages on page 3-60. You will also hear a chime.There is also an engine coolant temperature gage on
the instrument panel cluster. SeeEngine Coolant
Temperature Gage on page 3-49.
You may decide not to lift the hood when this warning
appears, but instead get service help right away.
SeeRoadside Service on page 8-7.
If you do decide to lift the hood, make sure the vehicle
is parked on a level surface.
Then check to see if the engine cooling fans are
running. If the engine is overheating, both fans should
be running. If they are not, do not continue to run
the engine and have the vehicle serviced.
Notice:Engine damage from running the engine
without coolant is not covered by the warranty.
Notice:If the engine catches re while driving
with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the
vehicle warranty. SeeOverheated Engine Protection
Operating Mode on page 6-29for information on
driving to a safe place in an emergency.

Speed Rating:An alphanumeric code assigned to
a tire indicating the maximum speed at which a
tire can operate.
Traction
:The friction between the tire and the
road surface. The amount of grip provided.
Tread
:The portion of a tire that comes into
contact with the road.
Treadwear Indicators
:Narrow bands, sometimes
called wear bars, that show across the tread of a
tire when only 1/16 inch (1.6 mm) of tread remains.
SeeWhen It Is Time for New Tires on page 6-61.
UTQGS (Uniform Tire Quality Grading
Standards)
:A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings
are determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. SeeUniform
Tire Quality Grading on page 6-64.
Vehicle Capacity Weight
:The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
SeeLoading the Vehicle on page 5-21.
Vehicle Maximum Load on the Tire
:Load on an
individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.Vehicle Placard
:A label permanently attached to
a vehicle showing the vehicle’s capacity weight
and the original equipment tire size and
recommended ination pressure. See “Tire and
Loading Information Label” underLoading
the Vehicle on page 5-21.
Run-Flat Tires
Your vehicle, when new, had run-at tires. There is no
spare tire, no tire changing equipment, and no place to
store a tire in the vehicle. Run-at tires perform so well
without any air that a Tire Pressure Monitor System
(TPMS) is used to alert you if a tire has lost pressure.
{CAUTION:
When the low tire warning light is displayed on the
instrument panel cluster, your vehicle’s handling
capabilities will be reduced during severe
maneuvers. If you drive too fast, you could lose
control of your vehicle. You or others could be
injured. Do not drive over 55 mph (90 km/h) when
the low tire warning light is displayed. Drive
cautiously and check your tire pressures as soon
as you can.

Federal Communications Commission
(FCC) and Industry and Science Canada
The Tire Pressure Monitor System (TPMS) operates
on a radio frequency and complies with Part 15 of
the FCC Rules. Operation is subject to the following
two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
The TPMS operates on a radio frequency and complies
with RSS-210 of Industry and Science 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.
Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor
System (TPMS). The TPMS is designed to warn the
driver when a low tire pressure condition exists. TPMS
sensors are mounted onto each tire and wheel
assembly on your vehicle. The TPMS sensors monitor
the air pressure in the vehicle’s tires and transmits
the tire pressure readings to a receiver located in the
vehicle.
When a low tire pressure
condition is detected, the
TPMS illuminates the low
tire pressure warning light,
located in the instrument
panel cluster.
