display CADILLAC DTS 2009 1.G Owners Manual

Using the DIC, tire pressure levels can be viewed by the
driver. For additional information and details about the
DIC operation and displays seeDIC Operation and
Displays on page 3-68andDIC Warnings and Messages
on page 3-73.
The low tire pressure warning light may come on in cool
weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be inated to the proper pressure.
A Tire and Loading Information label, attached to your
vehicle, shows the size of your vehicle’s original
equipment tires and the correct ination pressure for
your vehicle’s tires when they are cold. SeeLoading the
Vehicle on page 4-19, for an example of the Tire and
Loading Information label and its location on your
vehicle. Also seeInflation - Tire Pressure on page 5-57.
Your vehicle’s TPMS can warn you about a low tire
pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-65andTires on page 5-48.
Notice:Liquid tire sealants could damage the Tire
Pressure Monitor System (TPMS) sensors. Sensor
damage caused by using a tire sealant is not covered
by your warranty. Do not use liquid tire sealants.TPMS Malfunction Light and Message
The TPMS will not function properly if one or more of the
TPMS sensors are missing or inoperable. When the
system detects a malfunction, the low tire warning light
ashes for about one minute and then stays on for the
remainder of the ignition cycle. A DIC warning message
is also displayed. The low tire warning light and DIC
warning message come on at each ignition cycle until the
problem is corrected. Some of the conditions that can
cause the malfunction light and DIC message to come
on are:
One of the road tires has been replaced with the
spare tire. The spare tire does not have a TPMS
sensor. The TPMS malfunction light and DIC
message should go off once you re-install the road
tire containing the TPMS sensor.
The TPMS sensor matching process was started but
not completed or not completed successfully after
rotating the vehicle’s tires. The DIC message and
TPMS malfunction light should go off once the TPMS
sensor matching process is performed successfully.
See “TPMS Sensor Matching Process” later in this
section.
5-62

You have two minutes to match the rst tire/wheel
position, and ve minutes overall to match all four
tire/wheel positions. If it takes longer than two minutes, to
match the rst tire and wheel, or more than ve minutes
to match all four tire and wheel positions the matching
process stops and you need to start over.
The TPMS sensor matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to ON/RUN with the
engine off.
3. Press the Remote Keyless Entry (RKE) transmitter’s
lock and unlock buttons at the same time for
approximately ve seconds. The horn sounds twice
to signal the receiver is in relearn mode and TIRE
LEARNING ACTIVE message displays on the DIC
screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPMS sensor by increasing or
decreasing the tire’s air pressure for ve seconds,
or until a horn chirp sounds. The horn chirp,which may take up to 30 seconds to sound,
conrms that the sensor identication code has
been matched to this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat
the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat
the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the
procedure in Step 5. The horn sounds two times to
indicate the sensor identication code has been
matched to the driver side rear tire, and the TPMS
sensor matching process is no longer active.
The TIRE LEARNING ACTIVE message on the DIC
display screen goes off.
9. Turn the ignition switch to LOCK/OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems.

Scheduled Maintenance
To maintain the ride, handling, and performance of
the vehicle, it is important that the rst tire rotation
service be performed when the vehicle has 5,000 to
8,000 miles (8 000 to 13 000 km). Check tires for
ination pressures and wear. SeeTires on page 5-48.
Rotate tires. SeeTire Inspection and Rotation on
page 5-65and “Tire Wear Inspection” inAt Least Once
a Month on page 6-9.
When the CHANGE ENGINE OIL SOON message
displays in the Driver Information Center (DIC), service
is required for the vehicle. Have the vehicle serviced
as soon as possible within the next 600 miles
(1 000 km). It is possible that, if driving under the best
conditions, the engine oil life system may not indicate
that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must
be reset. Your dealer/retailer has trained service
technicians who will perform this work using genuine
parts and reset the system.
If the engine oil life system is ever reset accidentally,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-16for information on the Engine
Oil Life System and resetting the system.When the CHANGE ENGINE OIL SOON message
appears, the following services, checks, and inspections
are required:
❑Change engine oil and lter. SeeEngine Oil on
page 5-13. Reset oil life system. SeeEngine Oil Life
System on page 5-16.An Emission Control Service.
❑Visually check for any leaks or damage.
See footnote (k).
❑Inspect engine air cleaner lter. If necessary, replace
lter. SeeEngine Air Cleaner/Filter on page 5-17.
See footnote (m).
❑Rotate tires and check ination pressures and wear.
SeeTire Inspection and Rotation on page 5-65and
“Tire Wear Inspection” inAt Least Once a Month on
page 6-9.
❑Inspect brake system.See footnote (a).
❑Check engine coolant and windshield washer uid
levels and add uid as needed.
❑Perform any needed additional services.
See “Additional Required Services” in this section.
❑Inspect suspension and steering components.
See footnote (b).
❑Inspect engine cooling system.See footnote (c).
❑Inspect wiper blades.See footnote (d).
❑Inspect restraint system components.See footnote (e).
❑Lubricate body components.See footnote (f).
❑Check transmission uid level and add uid
as needed.
