Instruments and Controls 5-13
Speedometer
The speedometer shows the
vehicle's speed in either kilometers
per hour (km/h) or miles per
hour (mph).
Odometer
The odometer shows how far the
vehicle has been driven, in either
kilometers or miles.
This vehicle has a tamper‐resistant
odometer. The digital odometer will
read 999,999 if it is turned back.
If the vehicle needs a new odometer
installed, it must be set to the
mileage total of the old odometer.
If that is not possible, then it must
be set at zero and a label must be
put on the driver door to show the
old mileage reading when the new
odometer was installed.
Trip Odometer
The trip odometer can record the
number of kilometers or miles
traveled for up to two trips.The trip odometer is part of the
Driver Information Center (DIC); for
more information see
Driver
Information Center (DIC)
on
page 5‑27.
For vehicles that have the
navigation system, see the
Navigation System manual for more
information.
Tachometer
The tachometer displays the engine
speed in revolutions per
minute (rpm).
Notice: If the engine is operated
with the tachometer in the shaded
warning area, the vehicle could
be damaged, and the damages
would not be covered by the
vehicle warranty. Do not operate
the engine with the tachometer in
the shaded warning area.
The CTS-V tachometer has tracer
lights that follow the movement of
the tachometer indicator. The tracer
lights also flash when it is time to
up-shift to avoid the engine speed limit. See
Automatic Transmission
on page 9‑26orManual
Transmissionon page 9‑30for
more information.
Fuel Gauge
When the ignition is on, the fuel
gauge indicates how much fuel is
left in the tank.
An arrow on the fuel gauge
indicates the side of the vehicle the
fuel door is on.

5-14 Instruments and Controls
When the indicator nears empty, the
low fuel light comes on. More fuel is
needed soon.
The Fuel Level Low message
appears in the Driver Information
Center (DIC) and a single chime
sounds. SeeFuel System
Messages
on page 5‑36for more
information.
Normal operation of the fuel gauge
includes:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
.It takes a little more or less fuel
to fill up than the gauge
indicated.
.The gauge moves a little while
turning a corner or speeding up.
.The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.
Boost Gauge
English
Metric
For the CTS-V, this gauge is located
in the instrument panel cluster.
This gauge indicates positive
manifold pressure which is the
induction air pressure level in the
intake manifold before it enters the
combustion chamber. This gauge
reads zero under light throttle before
boost is generated.
The gauge automatically resets to
zero every time the engine is
started.

Engine Speed Limiter
This feature prevents the engine
speed from reaching an unsafe
level. If the level is too high, the
throttle closes or limits the fuel
supply until the engine speed
returns to a safe level. Throttle
operation and fuel supply return to
normal when engine speed is
lowered.
For the CTS-V, the tachometer
tracer lights flash prior to reaching
engine speed limit. The tracer lights
also flash on automatic transmission
vehicles while in the DSC or Tap
Shift modes.
Engine Oil Pressure
Gauge
English
Metric
For vehicles with an engine oil
pressure gauge, it shows the engine
oil pressure in kPa (kilopascals)
or psi (pounds per square inch)
when the engine is running.
Oil pressure may vary with engine
speed, outside temperature, and oil
viscosity, but if readings are outside
the normal operating range, the oil
pressure light will come on. See
Engine Oil Pressure Light
on
page 5‑26for more information.

Black plate (16,1)Cadillac CTS/CTS-V Owner Manual - 2011
5-16 Instruments and Controls
A reading outside the normal
operating range may be caused by
a dangerously low oil level or some
other problem causing low oil
pressure. Oil should be checked as
soon as possible. See Oil Pressure
Low Stop Engine underDriver
Information Center (DIC)
on
page 5‑27and Engine Oilon
page 10‑11.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule in this manual for
changing engine oil.
Engine Coolant
Temperature Gauge
English
Metric
This gauge shows the engine
coolant temperature. If the engine
coolant overheats, the engine
coolant temperature warning light
comes on. See Engine Coolant
Temperature Warning Light

Safety Belt Reminders
Driver Safety Belt Reminder
Light
There is a driver safety belt
reminder light on the instrument
panel cluster.
When the engine is started, this light
comes on and a chime sounds for
several seconds to remind a driver
to fasten the safety belt, unless the
driver safety belt is already buckled.
The safety belt light flashes for
several seconds, then comes on
solid for several more.
This cycle repeats if the driver
remains unbuckled and the vehicle
is moving.If the driver safety belt is already
buckled, neither the light nor the
chime comes on.
Passenger Safety Belt
Reminder Light
Several seconds after the engine is
started, a chime sounds for a
number of seconds to remind the
front passenger to buckle their
safety belt. The passenger safety
belt light comes on and stays on for
several seconds, flashes for several
more seconds, and then comes on
solid for several more.
This cycle repeats if the passenger
remains unbuckled and the vehicle
is moving.
If the passenger safety belt is
buckled, neither the chime nor the
light comes on.The front passenger safety belt
warning light and chime may turn on
if an object such as a briefcase,
handbag, grocery bag, laptop,
or other electronic device is put on
the seat . To turn off the warning
light and/or chime, remove the
object from the seat or buckle the
safety belt.
Airbag Readiness Light

{WARNING
If the airbag readiness light ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light
on page 5‑17for more
information, including important
safety information.
Charging System Light
The charging system light comes on
briefly when the ignition is turned
on, but the engine is not running, as
a check to show the light is working.
It should go out when the engine is
started. If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, the Driver
Information Center (DIC) also
displays a message.
See
Battery Voltage and Charging
Messages on page 5‑31.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It ensures that emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light should come on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
If the Malfunction Indicator Lamp
comes on and stays on while the
engine is running, this indicates that
there is an OBD II problem and
service is required.

Black plate (20,1)Cadillac CTS/CTS-V Owner Manual - 2011
5-20 Instruments and Controls
Malfunctions often are indicated by
the system before any problem is
apparent. Being aware of the light
can prevent more serious damage
to the vehicle. This system assists
the service technician in correctly
diagnosing any malfunction.
Notice:If the vehicle is
continually driven with this light
on, after a while, the emission
controls might not work as well,
the vehicle's fuel economy might
not be as good, and the engine
might not run as smoothly. This
could lead to costly repairs that
might not be covered by the
vehicle warranty.
Notice: Modifications made to the
engine, transmission, exhaust,
intake, or fuel system of the
vehicle or the replacement of the
original tires with other than
those of the same Tire
Performance Criteria (TPC) can
affect the vehicle's emission
controls and can cause this light
to come on. Modifications to
these systems could lead to costly repairs not covered by the
vehicle warranty. This could also
result in a failure to pass a
required Emission Inspection/
Maintenance test. See
Accessories and Modifications
on
page 10‑4.
This light comes on during a
malfunction in one of two ways:
Light Flashing: A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
To prevent more serious damage to
the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible. If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the vehicle off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible.
Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.

Black plate (21,1)Cadillac CTS/CTS-V Owner Manual - 2011
Instruments and Controls 5-21
An emission system malfunction
might be corrected:
.Make sure the fuel cap is fully
installed. SeeFilling the Tankon
page 9‑50. The diagnostic
system can determine if the fuel
cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out. A few
driving trips should turn the
light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and can
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.
See Recommended Fuel
on
page 9‑47.
If none of the above have made the
light turn off, your dealer can check
the vehicle. The dealer has the
proper test equipment and
diagnostic tools to fix any
mechanical or electrical problems
that might have developed.
Emissions Inspection and
Maintenance Programs
Some state/provincial and local
governments may have programs to
inspect the on-vehicle emission
control equipment. For the
inspection, the emission system test
equipment is connected to the
vehicle’s Data Link
Connector (DLC).
The DLC is under the instrument
panel to the left of the steering
wheel. See your dealer if assistance
is needed.
