2007 CADILLAC XLR fuel pressure

When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
light, located in the instrument panel cluster,
and at the same time the LOW TIRE PRESSURE
warning message on the Driver Information
Center (DIC) displays. The low tire pressure
warning light and the DIC warning message
appear at each ignition cycle until the tires are
inated to the correct ination pressure. For
additional information and details about the DIC
operation and displays seeDIC Controls and
Displays on page 204andDIC Warnings
and Messages on page 206.
You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
LOW TIRE PRESSURE DIC warning message
may come on when the vehicle is rst started, and
then turn off as you start to drive. This may be
an early indicator that the air pressure in the tire(s)
is getting low and needs to be inated to the
proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires ofa different size than the size indicated on the
vehicle placard or tire ination pressure label, you
should determine the proper tire ination
pressure for those tires.)
As an added safety
feature, your vehicle
has been equipped with
a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one
or more of your tires is
signicantly
under-inated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inate them to the
proper pressure. Driving on a signicantly
under-inated tire causes the tire to overheat and
can lead to tire failure. Under-ination also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.

(h)If you drive regularly under dusty conditions,
inspect the lter at each engine oil change.
(j)Visually inspect belt for fraying, excessive
cracks, or obvious damage. Replace belt if
necessary.
(k)Drain, ush, and rell intercooler system. This
service can be complex; you should have your
dealer perform this service. See Engine Coolant on
page 385 for what to use. Inspect hoses. Clean
pressure cap and ller neck. Pressure test
the system and pressure cap.
(l)For supercharged engines only: Have your
dealer check the supercharger oil level and add
the proper supercharger oil as needed (or every
36 months, whichever occurs rst). See
Recommended Fluids and Lubricants on page 473.
Owner Checks and Services
These owner checks and services should be
performed at the intervals specied to help ensure
the safety, dependability, and emission control
performance of your vehicle. Your GM
Goodwrench
®dealer can assist you with these
checks and services.Be sure any necessary repairs are completed at
once. Whenever any uids or lubricants are added
to your vehicle, make sure they are the proper
ones, as shown inRecommended Fluids and
Lubricants on page 473.
At Each Fuel Fill
It is important to perform these underhood checks
at each fuel ll.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 377for
further details.
Notice:It is important to check your oil
regularly and keep it at the proper level. Failure
to keep your engine oil at the proper level
can cause damage to your engine not covered
by your warranty.
Engine Coolant Level Check
Check the engine coolant level and add
DEX-COOL®coolant mixture if necessary. See
Engine Coolant on page 385for further details.
