Controls (CTS)
Your vehicle may have four controls that can be
programmed for use with the climate control

The TC warning light will come on briey when
you turn the ignition to ON. If it does not come on
then, have it xed so it will be ready to warn
you if there is a problem.
The light will also come on if you turn the traction
control system off using the TC on/off button
located in the glove box for the CTS and on the
steering wheel for the CTS-V.
If the TC warning light stays on or comes on while
you are driving, pull off the road as soon as
possible and stop carefully. Try resetting the
system by turning the ignition off then back on.
If the light still stays on or comes back on
again while you are driving, your vehicle needs
service. Have the Traction Control System (TCS)
inspected as soon as possible. SeeTraction
Control System (TCS) (CTS) on page 293
orTraction Control System (TCS) (CTS-V) on
page 295for more information.Engine Coolant Temperature
Warning Light (CTS)
This light will come on
when you rst start the
vehicle as a check
to let you know that the
light is working.
It will go out after a few seconds. If the light does
not come on, see your dealer.
If the light does not go out or if the light comes on
and stays on while you are driving, your vehicle
may have a problem with the cooling system. You
should stop the vehicle and turn off the engine
as soon as possible to avoid damage to the
engine. A warning chime will also sound when this
light is on.
SeeEngine Overheating on page 360for more
information.

Here are a few concerns some owners have had
about the fuel gage. All of these situations are
normal and do not indicate that anything is wrong
with the fuel gage:
At the gas station the gas pump shuts off
before the gage reads full.
The gage may change when you turn, stop
quickly or accelerate quickly.
It takes a little more or less fuel to ll the tank
than the gage indicated. For example, the gage
may have indicated that the tank was half full,
but it actually took a little more or less than half
the tank’s capacity to ll the tank.
Message Center
Message Center (CTS-V)
Your vehicle may have a message center that can
display information relating to powertrain uids, tire
pressures, vehicle dynamics, speedometer and
odometer information, and transmission status.
It also displays warning messages. There are
two different areas where message center
information will be displayed. One display is inside
of the tachometer and the other is inside of the
speedometer.These are the controls
for the message center.
They are located on
the left spoke of
the steering wheel.
The outboard switch (A and B) controls the display
of information inside of the tachometer. The
upper button (C) on the inboard switch controls
the display of information inside of the
speedometer. The lower button (D) on the inboard
switch turns the traction control on or off. See
Traction Control System (TCS) (CTS) on page 293
orTraction Control System (TCS) (CTS-V) on
page 295for more information.

Transmission Fluid Hot Message
When you see this
ashing symbol, the
transmission uid
temperature is high
(290°F (143°C)).
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press this button, the
warning will redisplay every 10 minutes until the
temperature returns to the normal operating range.
If this message appears, you may continue to drive
at a slower speed while monitoring the transmission
uid temperature. Ideally, the transmission oil
temperature should not rise above 265°F (129°C). If
you regularly experience temperatures above this
limit due to high performance operation, it is
recommended to use an auxiliary uid cooler for the
transmission and differential. See your dealer for
details. If this warning is displayed during normal
vehicle operation on at roads, your vehicle may
need service. See your dealer for an inspection.
SeeDIC Warnings and Messages on page 232and
Manual Transmission Fluid on page 354for more
information.
Hot Coolant Temperature Warning
Message
When you see this
ashing symbol, the
engine coolant
temperature is high
(257°F (125°C)).
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press a button, this
warning will come on every 10 minutes until the
temperature returns to the normal operating range.
Driving aggressively or driving on long hills can
cause the engine coolant temperature to be higher
than normal. The Engine Coolant Temperature
Warning Light should also come on. SeeEngine
Coolant Temperature Warning Light (CTS) on
page 207for more information. If this warning is
displayed during normal vehicle operation on
at roads, your vehicle may need service.
See your dealer for an inspection.

Check Engine Oil Pressure Message
Your vehicle may have
this feature. When you
see this ashing
symbol, the engine oil
pressure is low.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press this button,
the warning will redisplay every 10 minutes until
the pressure returns to the normal operating
range. 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 Oil Pressure
Light should also come on. SeeOil Pressure Light
on page 212for more information.
Oil Temperature Warning Message
When you see this
ashing symbol, the
engine oil temperature
is high.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press a button, the
warning will come on every 10 minutes until the
temperature returns to the normal operating range.
Driving aggressively or driving on long hills can
cause the engine oil temperature to be higher than
normal. If this warning is displayed during
normal vehicle operation on at roads, your vehicle
may need service. See your dealer for an
inspection. SeeEngine Oil on page 346for more
information.

Tire Pressure Warning Message
When you see this
ashing symbol, one or
more of the vehicle’s
tires is either under
or over-inated.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. There are three levels of warning
for this display:
1. High Tire Pressure (above 42 psi (290 kPa))
2. Low Tire Pressure (below 25 psi (170 kPa))
3. Flat Tire (below 5 psi (35 kPa))For conditions 1 and 2, this warning will ash
ve times and the display will then show the tire
pressure gage. For condition 3, this warning
will ash continuously until the driver
acknowledges it. In any of the three cases, the
warning will redisplay every 10 minutes until
the situation is corrected. Conditions 2 and 3 will
also display a warning light elsewhere on the
cluster that will stay on after this warning is
acknowledged. SeeTire Pressure Light (CTS-V
Only) on page 208for more information. Also see
Tire Pressure Monitor System on page 405for
more information on tire pressure specications.
