2004 CADILLAC CTS V instrument cluster

The traction control system automatically comes on
whenever you start your vehicle. To limit wheel
spin, especially in slippery road conditions, you should
always leave the system on. But you can turn the
traction control system off if you ever need to. You
should turn the system off if your vehicle ever gets stuck
in sand, mud or snow and rocking the vehicle is
required. See “Rocking Your Vehicle” underIf You Are
Stuck: In Sand, Mud, Ice or Snow on page 4-32for
more information. See alsoWinter Driving on page 4-27
for information on using TCS when driving in snowy
or icy conditions.
You can turn the system
off by pressing the
TC (traction control)
button located on the
steering wheel.
If you press the TC button once, the traction control
system will turn off and the traction control system
warning light will come on. If you press the TC button
again within ve seconds, the traction control system will
remain off, the warning light will stay on, and the
stability system will enter Competitive Driving Mode.Competitive Driving will be displayed on the Driver
Information Center (DIC). SeeDIC Warnings and
Messages on page 3-70for more information. Press the
TC button again to turn the system back on. If you
press and hold the TC button for ve seconds,
the Stabilitrak
®and Traction Control systems will turn
off. Press the TC button again to turn Stabilitrak®
and Traction Control back on. For more information,
seeStabilitrak®System on page 4-11.
Competitive Driving Mode
The driver can select this optional handling mode by
pressing the Traction Control button on the steering
wheel twice within ve seconds. COMPETITIVE
DRIVING will be displayed in the DIC. Competitive driving
mode allows the driver to have control of the power
applied to the rear wheels, while the Stabilitrak
®system
helps steer the vehicle by selective brake application.
In competitive mode, the levels at which Stabilitrak
®is
engaged have been modied to better suit a performance
driving environment. When the instrument cluster light is
on, the Traction Control System will not be operating.
Adjust your driving accordingly.
When you press the Traction Control button again, or
turn the ignition to ACC, the Traction Control System will
be on. The traction engaged symbol will be displayed
temporarily in the DIC and a chime will be heard.

Engine Oil
If the oil pressure light
and/or the Oil Pressure
Low - Stop Engine
message on the DIC
appears on the instrument
cluster, it means you
need to check your engine
oil level right away.
For more information, see “Oil Pressure Low - Stop
Engine” underDIC Warnings and Messages on
page 3-70andOil Pressure Light on page 3-49.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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 5-12
for the location of the engine oil dipstick.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.
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.

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires perform
so well without any air that a Tire Pressure Monitor
(TPM) is used to alert you if a tire has lost pressure.
SeeTire Pressure Monitor System (CTS-V) on
page 5-70.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don’t drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.If a tire goes at, you won’t need to stop on the side of
the road to change the tire. You can just keep on
driving. The tire can operate effectively with no air
pressure for up to 65 miles (105 km) at speeds up to
55 mph (90 km/h). The shorter the distance you
drive and the slower the speed, the greater the chance
that the tire will not have to be replaced. When a tire
is lled with air, it provides a cushion between the road
and the wheel. Because you won’t have this cushion
when driving on a deated run-at tire, try to avoid
potholes that could damage your wheel and require
replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you’ve driven
on the tire in a deated condition. When a tire has been
damaged, or if you’ve driven any distance on a
run-at tire, check with an authorized run-at tire service
center to determine whether the tire can be repaired
or should be replaced. To maintain your vehicle’s run-at
feature, all replacement tires must be self-supporting
tires. As soon as possible, contact the nearest
authorized GM or run-at servicing facility for inspection
and repair or replacement. To locate the nearest GM
or run-at servicing facility, call Roadside Service.
SeeRoadside Service on page 7-6for details.

Tire Pressure Monitor
System (CTS-V)
The Tire Pressure Monitor (TPM) System uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted on
each run-at tire and wheel assembly. The TPM
sensors transmit tire pressure readings to a receiver
located in the vehicle. Using the Message Center,
tire pressure levels can be viewed by the driver.
For additional information about the message center
operation and displays, seeMessage Center (CTS-V)
on page 3-53.
When a low tire pressure condition is detected, a low
tire warning light, on the instrument panel cluster,
comes on to warn the driver.When the tire pressure
monitoring system warning
light is lit, 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 as
indicated on the vehicle’s tire information placard.
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. Each tire, should be checked monthly when
cold and set to the recommended ination pressure as
specied in the vehicle placard and owner’s manual.

Run-Flat Tires (CTS-V)
If your vehicle has run-at tires, there is no spare tire
and no tire changing equipment. Run-at tires can
operate effectively with no air pressure for a limited
distance and speed. These tires perform so well without
any air pressure that a Tire Pressure Monitor (TPM)
is used to alert you when there is a low tire condition.
{CAUTION:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle’s
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you
could lose control of your vehicle. You or
others could be injured. Don’t drive over
55 mph (90 km/h) when the low tire warning
light is displayed. Drive cautiously and check
your tire pressures as soon as you can.SeeRun-Flat Tires (CTS-V) on page 5-66andTire
Pressure Monitor System (CTS-V) on page 5-70,
for additional information.
{CAUTION:
Special tools and procedures are required to
service a run-at tire. If these special tools and
procedures aren’t used you or others could be
injured and your vehicle could be damaged.
Always be sure the proper tools and
procedures, as described in the service
manual, are used.
