2006 CADILLAC CTS V fuel pressure

{CAUTION:
Run-at tires are constructed differently than
other tires and could explode during improper
service. You or others could be injured or killed
if you attempt to repair, replace, dismount, or
mount a run-at tire. Let only an authorized
run-at service center repair, replace, dismount,
and mount run-at tires.
The valve stems on your run-at tires have sensors that
are part of the Tire Pressure Monitor System (TPMS).
These sensors contain batteries which are designed
to last for 10 years under normal driving conditions. See
your dealer if you ever need to have a wheel replaced,
or if the sensors ever need replacement.
Notice:Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in your
vehicle’s run-at tires. This damage would not
be covered by warranty. Do not use liquid sealants
in your vehicle’s run-at tires.
Ination - Tire Pressure
Tires need the correct amount of air pressure to operate
effectively.
Notice:Do not let anyone tell you that
under-ination or over-ination is all right. It is not.
If your tires do not have enough air (under-ination),
you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted on
the tire and wheel assembly. The TPMS sensors
transmit tire pressure readings to a receiver located in
the vehicle once every 60 seconds while the vehicle
is being driven, and once every 60 minutes if the vehicle
is stationary for more than 15 minutes.
If your vehicle has the base audio system, the Driver
Information Center (DIC) displays TPMS warnings and
messages on the radio’s display screen. SeeSystem
Controls on page 3-53andDIC Warnings and Messages
on page 3-61for additional information and details about
the DIC operation and displays. If your vehicle has the
Navigation system, TPMS warnings and messages are
displayed on the message center screen, located inside
the tachometer. SeeMessage Center (CTS-V) on
page 3-47for information about the message center
operation and displays.
If a low tire pressure condition is detected, the TPMS
will display the Check Tire Pressure message on
the DIC or message center and, at the same time,
illuminate the low tire pressure warning symbol on
the instrument panel cluster.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.
When the low tire pressure
telltale is illuminated, one
or more of your tires is
signicantly under-inated.
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.
The Tire and Loading Information label shows the size
of your vehicle’s original tires and their recommended
cold ination pressures. SeeLoading Your Vehicle
on page 4-32, for the location of the tire and loading
information label. Also seeInation - Tire Pressure
on page 5-65.

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 5-16for 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.
SeeEngine Coolant on page 5-26for 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 Ination Check
Visually inspect your vehicle’s tires and make sure they
are inated to the correct pressures. Do not forget to
check the spare tire. SeeTires on page 5-57for further
details. Check to make sure the spare tire is stored
securely. SeeChanging a Flat Tire (CTS Only)
on page 5-84.
Tire Wear Inspection
Tire rotation may be required for high mileage highway
drivers prior to the Engine Oil Life System service
notication. Check the tires for wear and, if necessary,
rotate the tires. SeeTire Inspection and Rotation
on page 5-71.
