Rear Climate Control System
The vehicle has a rear climate control system. The
base model includes air outlets in the rear of the center
console for cooling and under-seat air outlets for
heating. The temperature, amount of airflow, and the
air delivery mode is controlled automatically by the front
climate control system.
Some vehicles may have an optional climate control
panel for the rear passenger, located on the back of the
center console.

Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to the
warning lights and gauges could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle's functions. Some
warning lights come on briefly when the engine is
started to indicate they are working.
Gauges can indicate when there might be or there
is a problem with one of the vehicle's functions. Often
gauges and warning lights work together to indicate a
problem with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gauges shows there
could be a problem, check the section that explains
what to do. Follow this manual's advice. Waiting to do
repairs can be costly and even dangerous.

Speedometer and Odometer
The speedometer shows the speed in both kilometers
per hour (km/h) and miles per hour (mph). SeeDIC
Operation and Displays
on page 4‑70for more
information.
The odometer mileage can be checked without the
vehicle running. The vehicle's odometer works together
with the driver information center. The odometer can be
set for a Trip A and a Trip B. See “Trip Information”
under DIC Operation and Displays
on page 4‑70for
more information.
If the vehicle ever needs a new odometer installed, the
new one will be set to the correct mileage total of the
old odometer.
Tachometer
This gauge indicates the engine speed in revolutions
per minute (rpm).
Safety Belt Reminders
Driver Safety Belt Reminder Light
When the engine is started, 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
comes on and stays on
for several seconds, then
flashes for several more.
This chime and light are repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver
safety belt is already buckled, neither the chime nor the
light comes on.

Passenger Safety Belt Reminder Light
For vehicles equipped with the passenger safety belt
reminder light, several seconds after the engine is
started, a chime sounds for several seconds to remind
the front passenger to buckle their safety belt. The
passenger safety belt light, located on the instrument
panel, comes on and stays on for several seconds and
then flashes for several more.
This chime and light are
repeated if the passenger
remains unbuckled and
the vehicle is in motion.
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 is put on the seat such as a
briefcase, handbag, grocery bag, laptop or other
electronic device. To turn off the warning light and or
chime, remove the object from the seat or buckle the
safety belt.
Airbag Readiness Light
The system checks the airbag's electrical system for
possible malfunctions. If the light stays on it indicates
there is an electrical problem. The system check
includes the airbag sensor, the pretensioners, the
airbag modules, the wiring and the crash sensing and
diagnostic module. For more information on the airbag
system, see Airbag System on page 2‑57.
The airbag readiness
light flashes for a few
seconds when the engine
is started. If the light does
not come on then, have it
fixed immediately.

{WARNING:
If the airbag readiness light stays on after the
vehicle is started or comes on while driving, it
means the airbag system might not be working
properly. The airbags in the vehicle might not
inflate in a crash, or they could even inflate
without a crash. To help avoid injury, have the
vehicle serviced right away.
If there is a problem with the airbag system, an airbag
Driver Information Center (DIC) message can also
come on. See DIC Warnings and Messages
on
page 4‑76for more information.
Passenger Airbag Status Indicator
Your vehicle has the passenger sensing system. Your
overhead console has a passenger airbag status
indicator.
United StatesCanada
When you start the vehicle, the passenger airbag status
indicator will light ON and OFF, or the symbol for on and
off, for several seconds as a system check. If you use
remote start to start your vehicle from a distance, if your
vehicle has this feature, you may not see the system
check.

Then, after several more seconds, the status indicator
will light either ON or OFF, or either the on or off symbol
to let you know the status of the right front passenger's
frontal airbag.
If the word ON or the on symbol is lit on the passenger
airbag status indicator, it means that the right front
passenger's frontal airbag is enabled (may inflate).
{WARNING:
If the on indicator comes on when you have a
rear-facing child restraint installed in the right
front passenger's seat, it means that the
passenger sensing system has not turned off the
passenger's frontal airbag. A child in a rear-facing
child restraint can be seriously injured or killed if
the right front passenger's airbag inflates. This is
because the back of the rear-facing child restraint
would be very close to the inflating airbag. Do not
use a rear-facing child restraint in the right front
passenger's seat if the airbag is turned on.
{WARNING:
Even though the passenger sensing system is
designed to turn off the right front passenger's
frontal airbag if the system detects a rear-facing
child restraint, no system is fail-safe, and no one
can guarantee that an airbag will not deploy under
some unusual circumstance, even though it is
turned off. We recommend that rear-facing child
restraints be secured in the rear seat, even if the
airbag is off.
If the word OFF or the off symbol is lit on the airbag
status indicator, it means that the passenger sensing
system has turned off the right front passenger's frontal
airbag. See Passenger Sensing System
on page 2‑66for more on this, including important safety information.

Black plate (57,1)Cadillac STS Owner Manual - 2011
If, after several seconds, both status indicator lights
remain on, or if there are no lights at all, there may
be a problem with the lights or the passenger sensing
system. See your dealer for service.
{WARNING:
If the airbag readiness light in the instrument
panel cluster ever comes on and stays on, it
means that something may be wrong with the
airbag system. If this ever happens, have the
vehicle serviced promptly, because an adult-size
person sitting in the right front passenger's seat
may not have the protection of the airbag(s). See
Airbag Readiness Light
on page 4‑54for more
on this, including important safety information.
Charging System Light
This light comes on briefly
when the ignition key is
turned to START, 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.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
See DIC Warnings and Messages
on page 4‑76for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
