2007 CADILLAC CTS instrument panel

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will
know how fast you are going, how much fuel you are using and many of the other things you will need
to know to drive safely and economically.

Engine Speed Limiter
This feature prevents the engine from operating at
too many revolutions per minute (rpm). When
the engine’s rpms are too high, the throttle
is closed to reduce speed. If this is not sufficient,
then the fuel supply to the engine will be
limited. When the rpms return to normal, the fuel
supply will return to normal. This helps prevent
damage to the engine.
Safety Belt Reminder Light
When the key is turned to ON or START, a chime
will come on for several seconds to remind
people to fasten their safety belts.
The safety belt light will
also come on and
stay on for several
seconds, then it will
ash for several more.
If the driver’s belt is already buckled, the chime
will not come on.
Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for
malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the diagnostic module. For more information on the
airbag system, seeAirbag System on page 70.
This light will come
on when the ignition
key is turned to ON
and it will ash for
a few seconds.
Then the light should go out. This means the
system is ready. If it does not go out, have your
vehicle serviced right away.

Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your
vehicle can affect the airow around it. This may
cause wind noise and affect windshield washer
performance. Check with your dealer before
adding equipment to the outside of your vehicle.
Fuel
Use of the recommended fuel is an important part
of the proper maintenance of your vehicle. To
help keep the engine clean and maintain optimum
vehicle performance, GM recommends the use
of gasoline advertised as TOP TIER Detergent
Gasoline.
The 8th digit of the Vehicle Identication Number
(VIN) shows the code letter or number that
identies your vehicle’s engine. The VIN is at the
top left of the instrument panel. SeeVehicle
Identication Number (VIN) on page 445.
Gasoline Octane
If your vehicle has the 2.8L V6 engine (VIN
Code T), use regular unleaded gasoline with a
posted octane rating of 87 or higher. If the octane
rating is less than 87, you may notice an audible
knocking noise when you drive, commonly referred
to as spark knock. If this occurs, use a gasoline
rated at 87 octane or higher as soon as possible.
If you are using gasoline rated at 87 octane or
higher and you hear heavy knocking, your engine
needs service.
If your vehicle has the 3.6L V6 engine (VIN
Code 7), use regular unleaded gasoline with a
posted octane rating of 87 or higher. For best
performance or trailer towing, you may choose to
use middle grade 89 octane unleaded gasoline.
If the octane rating is less than 87, you may notice
an audible knocking noise when you drive,
commonly referred to as spark knock. If this occurs,
use a gasoline rated at 87 octane or higher as soon
as possible. If you are using gasoline rated at
87 octane or higher and you hear heavy knocking,
your engine needs service.
