2007 CADILLAC XLR low oil pressure

Your vehicle will not pass this inspection if the
OBD (on-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle
would be considered not ready for inspection.
This can happen if you have recently replaced the
battery or if the battery has run down. The
diagnostic system is designed to evaluate critical
emission control systems during normal driving.
This may take several days of routine driving.
If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, your dealer can prepare the vehicle for
inspection.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 206andEngine Oil on
page 377.

{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others
could be burned. Check your oil as soon
as possible and have your vehicle
serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.

ABS (Anti-Lock Brake System)
ACTIVE
This message displays when the Anti-lock Brake
System (ABS) is adjusting brake pressure to
help avoid a braking skid.
Slippery road conditions may exist if this message
displays, so adjust your driving accordingly.
The message may stay on for a few seconds after
the system stops adjusting brake pressure.

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.

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.

When cleaning your vehicle’s interior, only use
cleaners specically designed for the surfaces
being cleaned. Permanent damage may result
from using cleaners on surfaces for which
they were not intended. Use glass cleaner only on
glass. Remove any accidental over-spray from
other surfaces immediately. To prevent over-spray,
apply cleaner directly to the cleaning cloth.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you
could scratch the glass and/or cause damage
to the integrated radio antenna and the
rear window defogger. When cleaning the
glass on your vehicle, use only a soft cloth and
glass cleaner.
Many cleaners contain solvents that may become
concentrated in your vehicle’s breathing space.
Before using cleaners, read and adhere to all safety
instructions on the label. While cleaning your
vehicle’s interior, maintain adequate ventilation by
opening your vehicle’s doors and windows.
Dust may be removed from small buttons and
knobs using a small brush with soft bristles.Your dealer has a product for cleaning your
vehicle’s glass. Should it become necessary, you
can also obtain a product from your dealer to
remove odors from your vehicle’s upholstery.
Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular
brake, set the parking brake.
To check the parking brake’s holding ability:
With the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure
from the regular brake pedal. Do this until the
vehicle is held by the parking brake only.
To check the PARK (P) mechanism’s holding
ability: With the engine running, shift to
PARK (P). Then release the parking brake
followed by the regular brake.
