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.

Instruments and Controls 5-15
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.

This message clears itself after
10 seconds, until the next ignition
cycle. SeeEngine Oil
on page 10‑11for additional information.
Oil Pressure Low Stop Engine
Notice:If you drive your vehicle
while the engine oil pressure is
low, severe engine damage may
occur. If a low oil pressure
warning appears on the
instrument panel cluster and/or
DIC, stop the vehicle as soon as
possible. Do not drive the vehicle
until the cause of the low oil
pressure is corrected. See Engine
Oil
on page 10‑11for more
information.
This message displays when the
vehicle's engine oil pressure is low.
The oil pressure light may also
appear on the instrument panel
cluster. See Engine Oil Pressure
Light
on page 5‑26. See Engine Oilon page 10‑11for more information.
Stop the vehicle immediately, as
engine damage can result from
driving a vehicle with low oil pressure. Have the vehicle serviced
by your dealer as soon as possible
when this message is displayed.
Engine Power Messages
Engine Power Is Reduced
This message displays when the
engine power is being reduced to
protect the engine from damage.
There could be several malfunctions
that might cause this message.
Reduced engine power can affect
the vehicle's ability to accelerate.
If this message is on, but there is no
reduction in performance, proceed
to your destination. The
performance may be reduced the
next time the vehicle is driven. The
vehicle may be driven at a reduced
speed while this message is on, but
acceleration and speed may be
reduced. Anytime this message
stays on, the vehicle should be
taken to your dealer for service as
soon as possible.
Fuel System Messages
Fuel Level Low
This message displays when the
vehicle is low on fuel. Refill the fuel
tank as soon as possible. A chime
may sound when this message
displays. See
Filling the Tank
on
page 9‑50.
Tighten Gas Cap
This message displays when the
fuel cap has not been fully
tightened. Recheck the fuel cap to
ensure that it is on and tightened
properly.
Key and Lock Messages
Accessory Mode Active
If the vehicle has the keyless
access system, this message
displays when the accessory mode
is active. See Ignition Positions (Key
Access)
on page 9‑16or Ignition
Positions (Keyless Access)on
page 9‑18for more information.

(F) Service Description:These
characters represent the load
index and speed rating of the
tire. The load index represents
the load carrying capacity a tire
is certified to carry. The speed
rating is the maximum speed a
tire is certified to carry a load.
Tire Terminology and
Definitions
Air Pressure:The amount of
air inside the tire pressing
outward on each square inch of
the tire. Air pressure is
expressed in psi (pounds per
square inch) or kPa (kilopascal).
Accessory Weight
:This
means the combined weight of
optional accessories. Some
examples of optional
accessories are, automatic
transmission, power steering, power brakes, power windows,
power seats, and air
conditioning.
Aspect Ratio
:The relationship
of a tire's height to its width.
Belt
:A rubber coated layer of
cords that is located between
the plies and the tread. Cords
may be made from steel or other
reinforcing materials.
Bead
:The tire bead contains
steel wires wrapped by steel
cords that hold the tire onto
the rim.
Bias Ply Tire
:A pneumatic tire
in which the plies are laid at
alternate angles less than
90 degrees to the centerline of
the tread.
Cold Tire Pressure
:The
amount of air pressure in a tire,
measured in psi (pounds per
square inch) or kPa (kilopascal) before a tire has built up heat
from driving. See
Tire Pressure
on page 10‑74.
Curb Weight
:The weight of a
motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil,
and coolant, but without
passengers and cargo.
DOT Markings
:A code molded
into the sidewall of a tire
signifying that the tire is in
compliance with the U.S.
Department of Transportation
(DOT) motor vehicle safety
standards. The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric
designator which can also
identify the tire manufacturer,
production plant, brand, and
date of production.

Rating. See Vehicle Load Limits
on page 9‑11.

Tire Pressure
Tires need the correct amount of
air pressure to operate
effectively.
Notice:Do not let anyone tell
you that under‐inflation or
over‐inflation is all right. It is
not. If your tires do not have
enough air (under‐inflation),
you can get the following:
.Tire overloading and
over-heating which could
lead to a blowout.
.Premature or
irregular wear.
.Poor handling.
.Reduced fuel economy.
If your tires have too much air
(over‐inflation), you can get
the following:
.Unusual wear.
.Poor handling.
.Rough ride.
.Needless damage from
road hazards.
A vehicle-specific Tire and
Loading Information label is
attached to your vehicle. This
label shows your vehicle's
original equipment tires and the
correct inflation pressures for
your tires when they are cold.
The recommended cold tire
inflation pressure, shown on the
label, is the minimum amount of
air pressure needed to support
your vehicle's maximum load
carrying capacity.
For additional information
regarding how much weight your
vehicle can carry, and an
example of the Tire and Loading
Information label, see Vehicle
Load Limits
on page 9‑11. How
you load your vehicle affects
vehicle handling and ride comfort. Never load your vehicle
with more weight than it was
designed to carry.
When to Check
Check your tires once a month
or more. Do not forget to check
the compact spare tire, if the
vehicle has one. The compact
spare should be at 420 kPa
(60 psi). For additional
information regarding the
compact spare tire, see
Compact Spare Tire
on
page 10‑111
.
How to Check
Use a good quality pocket-type
gauge to check tire pressure.
You cannot tell if your tires are
properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they are under‐inflated. Check
the tire's inflation pressure when
the tires are cold. Cold means
