seats CADILLAC STS 2008 1.G Owner's Manual

Reading Lamps
The reading lamps are located on the overhead console.
These lamps come on automatically when any door is
opened.
For manual operation, press the button next to each
lamp to turn it on or off.
If the reading lamps are left on, they automatically shut
off 10 minutes after the ignition has been turned off.
Battery Load Management
The battery load management feature is designed to
monitor the vehicle’s electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle
at a higher revolutions per minute (rpm) setting
than normal to make sure the battery charges.
High electrical loads may occur when several of the
following are on: headlamps, high beams, fog lamps,
rear window defogger, the climate control fan at
high speeds, heated seats and engine cooling fans.If the battery continues to discharge, even with the
engine idling at a higher rpm setting, some electrical
loads will automatically be reduced. When this occurs,
the rear window defogger may take slightly longer
to clear the glass and the fan may cut back to a lower
speed. For more battery saving information, see
“Battery Saver Active Message” underDIC Warnings
and Messages on page 3-80.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the voltage
is raised slightly to quickly put the charge back in.
When the state of charge is high, the voltage is lowered
slightly to prevent overcharging. If the vehicle has a
voltmeter gage or a voltage display on the Driver
Information Center (DIC), you may see the voltage
move up or down. This is normal. If there is a problem,
an alert will be displayed.
3-42

The battery can be discharged at idle if the electrical
loads are very high. This is true for all vehicles.
This is because the generator (alternator) may not be
spinning fast enough at idle to produce all the power
that is needed for very high electrical loads.
A high electrical load occurs when several of the
following loads are on: headlamps, high beams, fog
lamps, rear window defogger, climate control fan at
high speed, heated seats, engine cooling fans, trailer
loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the
battery. It does this by balancing the generator’s output
and the vehicle’s electrical needs. It can increase
engine idle speed to generate more power, whenever
needed. It can temporarily reduce the power demands
of some accessories.
Normally, these actions occur in steps or levels, without
being noticeable. In rare cases at the highest levels
of corrective action, this action may be noticeable to
the driver. If so, a Driver Information Center (DIC)
message might be displayed, such as Battery Saver
Active or Service Battery Charging System. If this
message is displayed, it is recommended that the
driver reduce the electrical loads as much as possible.
SeeDIC Warnings and Messages on page 3-80.Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp, or the garage door opener. When the
ignition is turned off, the power to these features will
automatically turn off after 10 minutes (three minutes if
a new car has 15 miles (24 km) or less). Power will
be restored for an additional 10 minutes if any door is
opened, the trunk is opened or the courtesy lamp switch
is turned on.
Head-Up Display (HUD)
{CAUTION:
If the HUD image is too bright, or too high in
your eld of view, it may take you more time
to see things you need to see when it is dark
outside. Be sure to keep the HUD image dim
and placed low in your eld of view.
For vehicles with the Head-Up Display (HUD), it projects
some of the driver information that appears on the
instrument panel cluster onto the windshield.

Cigarette Lighter
Notice:Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold
a cigarette lighter in while it is heating. Do not use
equipment exceeding maximum amperage
rating of 15 amperes.
The cigarette lighter is located next to the ashtray.
The vehicle does not have any cigarette lighters for
the rear seat passengers.
To activate the cigarette lighter, push it into the heating
element and let go. When the lighter is ready it will
pop back out by itself.

Vehicles Without Similar
3-48

Under some conditions, the air quality sensor system
does not operate. In cold weather, the system might
not be active (even if AUTO is displayed) because
of concerns of fogging your windows, which may occur
by activating recirculation mode. Also, the air quality
sensor system does not remain in recirculation mode
for extended periods of time that could cause stuffy
or very dry conditions in the vehicle. Following a poorly
running vehicle for an extended period of time may
not keep recirculation active indenitely.
The air quality sensor does not activate due to organic
odors, like skunk, and may not activate on many
chemical-related odors. If you wish to limit these types
of odors, manually select recirculation. Your vehicle
could also have a charcoal lter that can limit many
odors from being pulled into your vehicle. This
lter needs to be changed periodically. SeeScheduled
Maintenance on page 6-4. The air quality sensor
system does not protect against carbon monoxide (CO),
which you cannot see or smell. SeeEngine Exhaust
on page 2-38.

Outlet Adjustment
Use the lever located in the center of each outlet to
change the direction of the airow, either side-to-side
or up and down. Use the thumbwheels to open or close
the outlets to adjust the airow.
Turn the thumbwheel towards the vehicle door to open
the outlets and allow the maximum amount of air to
enter your vehicle. Turn the thumbwheel towards
the center console to close the outlets and minimize
the amount of air entering the vehicle.
Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
If the airow seems low when the fan speed is at the
highest setting, the passenger compartment air lter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-55.
Rear Climate Control System
Your 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, quantity, and
air delivery location is controlled automatically by
the front climate control system.
Some vehicles are equipped with an optional climate
control panel for the rear passenger, located on the
back of the center console.
The left knob controls the temperature of the air to
the rear passengers. Turning the knob to the left will
make the air cooler. Turning the knob to the right
will make the air warmer.
3-54

The right knob controls the air delivery to the rear
passengers. Turning the knob all the way to the left will
shut off airow to the rear passengers. Operating with
the rear air delivery off may make the entire vehicle
warm or cool less quickly. It may also increase the air
rush sound of the front system.
9(Off):This is the off position.
Y(Vent):This mode directs all the rear passenger
airow to the outlets in the console. This is the
normal position for cool down conditions.
\(Bi-Level):This mode directs airow to the
console outlets and the oor.
[(Floor):This mode directs all of the airow to the
oor. This is the normal position for warm up conditions.
The amount of airow to the rear passengers is
controlled automatically by the front climate control
system, regardless of optional equipment. Airow to
the rear system will be turned off when defrost is
selected on the front climate control panel to direct
air to clear the windshield.
Vehicles equipped with a rear climate control panel,
also, have heated rear seats. There are two buttons,
each with three indicator lights, located between thetwo climate control knobs on the rear climate control
panel, to control the rear heated seats. SeeHeated
Seats on page 1-7for additional information.
Be sure to keep the area under the front seats clear
of any objects so the air in your vehicle can circulate
effectively.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment air lter. There are two types of lters
available. There is a standard dust lter that traps small
particles including pollen. There is, also, a dust/odor
lter available that traps dust and pollen and also uses
a charcoal element to help reduce many offensive
odors from entering your vehicle. The lter will need
to be changed periodically. For information on how
often to change the passenger compartment air lter,
seeScheduled Maintenance on page 6-4.
Notice:Driving without a passenger compartment
air lter in place can cause water and small particles,
like paper and leaves, to be pulled into your climate
control system which may cause damage to it. Make
sure you always replace the old lter with a new one.

If you put things inside your vehicle, like suitcases,
tools, packages, or anything else, they will go as
fast as the vehicle goes. If you have to stop or turn
quickly, or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can
strike and injure people in a sudden stop
or turn, or in a crash.
Put things in the trunk of your vehicle.
In a trunk, put them as far forward as
you can. Try to spread the weight
evenly.
Never stack heavier things, like
suitcases, inside the vehicle so that
some of them are above the tops of
the seats.
Do not leave an unsecured child
restraint in your vehicle.
