2007 CADILLAC XLR V brake fluid

If the light comes on while you are driving and you
have a LOW BRAKE FLUID message showing
on the DIC, pull off the road and stop carefully.
You may notice that the pedal is harder to
push. Or, the pedal may go closer to the oor. It
may take longer to stop. If the light is still on, have
the vehicle towed for service. SeeTowing Your
Vehicle on page 359.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light
is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the Anti-Lock
Brake System (ABS),
this light will come
on when your engine is
started and may stay
on for several seconds.
That is normal.
If the light stays on, turn the ignition off or if the light
comes on 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 light still
stays on, or comes on again while you are driving,
your vehicle needs service. If the regular brake
system warning light is not on, you still have brakes,
but you do not have anti-lock brakes. If the regular
brake system warning light is also on, you do not
have anti-lock brakes and there is a problem with
your regular brakes. See “Service ABS” underDIC
Warnings and Messages on page 206.
The ABS warning light will come on briey when
you turn the ignition on. This is normal. If the
light does not come on then, have it xed so it will
be ready to warn you if there is a problem.

LEFT DOOR AJAR
This message displays anytime the engine is
running, the transmission is not in PARK (P), and
the driver’s door is open or ajar. A chime
sounds when the vehicle’s speed is greater than
3 mph (5 km/h).
LOW BRAKE FLUID
This message displays if the engine is running to
inform the driver that the brake uid level is
low. Have the brake system serviced by your
dealer as soon as possible. See “Brake Fluid”
underBrakes on page 399.
LOW COOLANT
This message displays when there is a low level
of engine coolant. Have the cooling system
serviced by your dealer as soon as possible. See
Engine Coolant on page 385.
LOW FUEL
This message displays when the fuel supply is
less than 5 gallons (18.9 L) and the display
is turned off. A single chime also sounds when
this message is displayed.
LOW OIL LEVEL
For correct operation of the low oil sensing
system, your vehicle should be on a level surface.
A false LOW OIL LEVEL message may display
if the vehicle is parked on a grade. The oil
level sensing system does not check for actual oil
level if the engine has been off for a short
period of time, and the oil level is never checked
while the engine is running. If the LOW OIL
LEVEL message displays, and your vehicle has
been parked on level ground with the engine off for
at least 30 minutes, the oil level should be
checked by observing the oil dipstick. Prior to
checking the oil level, make sure the engine has
been off for a few minutes and your vehicle is on a
level surface. Then check the dipstick and add
oil if necessary. SeeEngine Oil on page 377.
LOW OIL PRESSURE
If this message displays while the engine is
running, stop the engine and do not operate the
vehicle until the cause of low oil pressure is
corrected. Severe damage to the engine can
result. A multiple chime sounds when this
message is displayed.

If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center
(DIC) appears, it means you need to check the
engine oil level right away. For more information,
see LOW OIL LEVEL and LOW OIL PRESSURE
underDIC Warnings and Messages on page 206.
You should check the engine oil level regularly;
this is an added reminder.
Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. In order to get an accurate reading,
the oil must be warm and the vehicle must be
on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 374
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several
minutes to drain back into the oil pan. If you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out the dipstick and clean it with a paper
towel or cloth, then push it back in all the
way. Remove it again, keeping the tip down,
and check the level.

Brakes
Brake Fluid
Your brake master
cylinder reservoir is
lled with DOT-3 brake
uid. SeeEngine
Compartment Overview
on page 374for the
location of the reservoir.
There are only two reasons why the brake uid
level in the reservoir might go down. The rst
is that the brake uid goes down to an acceptable
level during normal brake lining wear. When
new linings are put in, the uid level goes back
up. The other reason is that uid is leaking out of
the brake system. If it is, you should have your
brake system xed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.So, it is not a good idea to top off your brake uid.
Adding brake uid will not correct a leak. If you
add uid when your linings are worn, then you will
have too much uid when you get new brake
linings. You should add or remove brake uid, as
necessary, only when work is done on the
brake hydraulic system.
{CAUTION:
If you have too much brake uid, it can
spill on the engine. The uid will burn if
the engine is hot enough. You or others
could be burned, and your vehicle could
be damaged. Add brake uid only when
work is done on the brake hydraulic
system. See “Checking Brake Fluid” in
this section.
Refer to the Maintenance Schedule to determine
when to check your brake uid. SeeScheduled
Maintenance on page 465.
399

Checking Brake Fluid
You can check the brake uid without taking off
the cap. Look at the brake uid reservoir. The uid
level should be above the MIN mark on the
reservoir. If it is not, have your brake system
checked to see if there is a leak.
After work is done on the brake hydraulic system,
make sure the level is between the MIN and
MAX marks.
What to Add
When you do need brake uid, use only DOT-3
brake uid. Refer toRecommended Fluids
and Lubricants on page 473. Use new brake uid
from a sealed container only.
Always clean the brake uid reservoir cap and the
area around the cap before removing it. This
will help keep dirt from entering the reservoir.
{CAUTION:
With the wrong kind of uid in the brake
system, the brakes may not work well, or
they may not even work at all. This could
cause a crash. Always use the proper
brake uid.
Notice:
Using the wrong uid can badly damage
brake system parts. For example, just a
few drops of mineral-based oil, such
as engine oil, in the brake system can
damage brake system parts so badly that
they will have to be replaced. Do not
let someone put in the wrong kind of uid.
If you spill brake uid on your vehicle’s
painted surfaces, the paint nish can
be damaged. Be careful not to spill brake
uid on your vehicle. If you do, wash it
off immediately. SeeWashing Your Vehicle
on page 446.

Intercooler Coolant Level Check
(4.4L Supercharged Engine)
Check the coolant level and add DEX-COOL®
coolant mixture if necessary. SeeEngine Coolant
on page 385for further details.
Windshield Washer Fluid Level Check
Check the windshield washer uid level in
the windshield washer uid reservoir and add the
proper uid if necessary.
At Least Once a Month
Tire Inspection and Ination Check
Visually inspect your vehicle’s tires for wear and
make sure they are inated to the correct
pressures. SeeInation - Tire Pressure on
page 422.
At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the
vehicle moves, you or others could be
injured.
1. Before you start, be sure you have enough
room around the vehicle.
2. Firmly apply both the parking brake and the
regular brake. SeeParking Brake on page 97.
Do not use the accelerator pedal, and be
ready to turn off the engine immediately if it
starts.
3. Try to start the engine in each gear. The
vehicle should start only in PARK (P) or
NEUTRAL (N). If the vehicle starts in any
other position, contact your GM Goodwrench
®
dealer for service.
