2009 CADILLAC XLR warning

Charging System Light
This light comes on briey
when the ignition key is
turned to START, but
the engine is not running,
as a check to show it
is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-60for more
information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Voltmeter Gage
When the vehicle is in
accessory mode, the
voltmeter shows the
voltage output of the
battery. When the engine
is running, it shows
the voltage output of the
charging system.
The reading will change as the rate of charge changes
(with engine speed, for example), but if the voltmeter
reads at 9 volts or below, the instrument panel cluster
and other systems may shut down. The Driver
Information Center (DIC) will read LOW VOLTAGE
when the vehicle is at 10 volts or below. Have it checked
right away. Driving with the voltmeter reading at
10 volts or below could drain the battery and disable
the vehicle.

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

on, the vehicle still has brakes, but not antilock brakes.
If the regular brake system warning light is also on,
the vehicle does not have antilock brakes and there is a
problem with the regular brakes. SeeBrake System

dealer/retailer. If the system is working normally the
indicator lights go off.
If the light stays on, or comes on while driving and
the DIC shows a SERVICE TRACTION SYS or
a SERVICE STABILITRAK message, there is a
problem with the Traction Control System (TCS)
or the StabiliTrak
®system and the vehicle needs
service.

This gage shows the engine coolant temperature.
As the pointer nears 260°F (125°C), your engine coolant
temperature is high. A message may display on the
Driver Information Center (DIC) depending on how high
the temperature is. SeeDIC Warnings and Messages

Malfunction Indicator Lamp
Check Engine Light
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation of
the fuel, ignition, and emission control systems. It makes
sure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment.
This comes on briey
while starting the engine.
If it does not come on,
have the vehicle serviced
by your dealer/retailer.
If the check engine light comes on and stays on, while
the engine is running, this indicates that there is an
OBD II problem and service is required.

Engine Oil Pressure Gage
The engine oil pressure gage shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 20 to 80 psi (140 to 550 kPa).
In certain situations such as long, extended idles on hot
days, it could read as low as 6 psi (40 kPa) and still
be considered normal. It may vary with engine speed,outside temperature and oil viscosity. The Driver
Information Center (DIC) may display messages
regarding the oil condition. SeeDIC Warnings and
Messages on page 3-60andEngine Oil on page 6-15.
{CAUTION:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches re.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice:Lack of proper engine oil maintenance can
damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil. United States
