2009 CADILLAC XLR low oil pressure

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

LOW OIL PRESSURE
Notice:If you drive your vehicle while the engine
oil pressure is low, severe engine damage may
occur. If a low oil pressure warning appears on the
Driver Information Center (DIC), stop the vehicle
as soon as possible. Do not drive the vehicle until
the cause of the low oil pressure is corrected.
SeeEngine Oil on page 6-15for more information.
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.
LOW VOLTAGE
This message displays when the electrical system
is charging less than 10 volts or if the battery has
been drained. If this message displays immediately
after starting, it is possible that the generator can still
recharge the battery. The battery should recharge while
driving, but may take a few hours to do so. Consider
using an auxiliary charger to boost the battery after
returning home or to a nal destination. Make sure you
follow the manufacturer’s instructions. If this message
displays while driving or after starting the vehicleand stays on, have it checked immediately by your
dealer/retailer to determine the cause of this problem.
To help the generator recharge the battery quickly,
you can reduce the load on the electrical system
by turning off the accessories. You can monitor battery
voltage on the DIC by pressing the INFO button.
The normal range is 11.5 to 15.5 volts.

If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center (DIC)
appears, check the engine oil level right away.
For more information, see LOW OIL LEVEL and
LOW OIL PRESSURE underDIC Warnings and
Messages on page 3-60. 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. See
Engine Compartment Overview on page 6-12for
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.
