Notice:Cranking the engine for
long periods of time, by returning
the key to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not start after
5-10 seconds, especially in very
cold weather (below 0°F or
−18°C), it could be ooded with
too much gasoline. Try pushing
the accelerator pedal all the way
to the oor and holding it there as
you hold the key in START for
up to a maximum of 15 seconds.
Wait at least 15 seconds between
each try, to allow the cranking
motor to cool down. When the

and accelerator. If the vehicle
starts brie y but then stops again,repeat these steps. This clears
the extra gasoline from the
engine. Do not race the engine
immediately after starting it.
Operate the engine and
transmission gently until the oil
warms up and lubricates all
moving parts.
Notice:The engine is designed to
work with the electronics in the
vehicle. If you add electrical parts
or accessories, you could change
the way the engine operates.
Before adding electrical
equipment, check with your
dealer/retailer. If you do not, the
engine might not perform
properly. Any resulting damage
would not be covered by the
vehicle warranty.Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. Some models
may have an internal thermostat
in the cord which will prevent engine
coolant heater operation at
temperatures above 0°F (−18°C).
To Use the Engine Coolant
Heater
1. Turn off the engine.
2. Open the hood and unwrap the
electrical cord. The cord is
located on the driver side of the
engine compartment. It is
routed around the windshield
washer uid reservoir.

How OnStar Service Works
The OnStar system can record and
transmit vehicle information. This
information is automatically sent to
an OnStar Call Center when the
OnStar button is pressed, the
emergency button is pressed, or if
the airbags or AACN system deploy.
This information usually includes
the vehicle’s GPS location and, in
the event of a crash, additional
information regarding the crash that
the vehicle was involved in (e.g.
the direction from which the vehicle
was hit). When the Virtual Advisor
feature of OnStar Hands-Free
Calling is used, the vehicle also
sends OnStar the vehicle’s
GPS location so they can provide
services where it is located.
OnStar service cannot work unless
the vehicle is in a place where
OnStar has an agreement with a
wireless service provider for service
in that area. OnStar service also
cannot work unless the vehicle is in a
place where the wireless serviceprovider OnStar has hired for that
area has coverage, network capacity
and reception when the service is
needed, and technology that is
compatible with the OnStar service.
Not all services are available
everywhere, particularly in remote or
enclosed areas, or at all times.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannot
control that may prevent OnStar
from providing OnStar service at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar
buttons is red, the system may not
be functioning properly. Press
the OnStar button and request a
vehicle diagnostic. If the light
appears clear (no light is appearing),
your OnStar subscription has
expired and all services have been
deactivated. Press the OnStar
button to con rm that the OnStar
equipment is active.

Delayed Entry Lighting
Delayed entry lighting illuminates
the interior for a period of time after
all the doors have been closed.
The ignition must be off for delayed
entry lighting to work. Immediately
after all the doors have been closed,
the delayed entry lighting feature
continues to work until one of
the following occurs:
The ignition is in ON/RUN.
The doors are locked.
An illumination period of about
25 seconds has elapsed.
If during the illumination period
a door is opened, the timed
illumination period is canceled
and the interior lamps remain on.
Delayed Exit Lighting
This feature illuminates the interior
for a period of time after the key
is removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
The ignition is in ON/RUN.
The power door locks are
activated.
An illumination period of
20 seconds has elapsed.
If during the illumination period
a door is opened, the timed
illumination period will be canceled
and the interior lamps will remain
on because a door is open.
Parade Dimming
Parade mode automatically prohibits
the dimming of the instrument panel
displays during the daylight while
the headlamps are on so that the
displays are still able to be seen.
Reading Lamps
The vehicle has reading lamps that
also act as the dome lamp. Press
the button to turn them on and off.
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.
Instrument Panel 3-15

When the battery’s state of charge is
low, the voltage is raised slightly to
quickly bring the charge back up.
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.
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 are on,
such as: 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, BATTERY
VOLTAGE LOW, or LOW BATTERY.
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 3-56.Battery Run-Down
Protection
This feature helps prevent
the battery from being drained,
if the interior courtesy lamps,
reading/map lamps, visor vanity
lamps or trunk lamp are accidentally
left on. If any of these lamps are left
on, they automatically turn off after
10 minutes, if the ignition is off.
The lamps will not come back on
again until one of the following
occurs:
The ignition is turned on.
The exterior lamps control is
turned off, then on again.
The headlamps will timeout after
10 minutes, if they are manually
turned on with the ignition on or off.
3-16 Instrument Panel

Accessory Power
Outlet(s)
Accessory power outlets let you plug
in auxiliary electrical equipment,
such as a cellular phone.
The vehicle may have four
accessory power outlets. They
are located on the instrument panel
below the climate controls, under
the front center console cupholders,
at the rear of the center console,
and in the rear cargo area.
To use the outlets, remove the
cover. When not in use, always cover
the outlet with the protective cap.
Notice:Leaving electrical
equipment on for extended
periods will drain the battery.Always turn off electrical
equipment when not in use and
do not plug in equipment that
exceeds the maximum amperage
rating of 20 amperes.
Certain electrical accessories
may not be compatible with the
accessory power outlets and could
result in blown vehicle or adapter
fuses. If you experience a problem,
see your dealer/retailer for
additional information on the
accessory power outlet.
Notice:Adding any electrical
equipment to the vehicle can
damage it or keep other
components from working as
they should. The repairs would
not be covered by the vehiclewarranty. Do not use equipment
exceeding maximum amperage
rating of 20 amperes. Check
with your dealer/retailer before
adding electrical equipment.
When adding electrical equipment,
be sure to follow the installation
instructions included with the
equipment.
Notice:Improper use of the
power outlet can cause damage
not covered by the warranty.
Do not hang any type of
accessory or accessory bracket
from the plug because the
power outlets are designed for
accessory power plugs only.
