Features and Controls 2-21

Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice:Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage
the transmission. Shift to P (Park)
only when the vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator
pedal, turn the ignition to
START. When the engine starts,
let go of the key. The idle
speed will slow down as the
engine warms. Do not race the
engine immediately after
starting it. Operate the engine
and transmission gently to allow
the oil to warm up and lubricate
all moving parts.The vehicle has a
Computer-Controlled Cranking
System. This feature assists
in starting the engine and
protects components. If the
ignition key is turned to
the START position, and then
released when the engine begins
cranking, the engine will
continue cranking for a
few seconds or until the vehicle
starts. If the engine does not
start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
cranking motor damage.
To prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch
to the ACC/ACCESSORY
or LOCK/OFF position.
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 damagethe 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
engine starts, let go of the key
and accelerator. If the vehicle
starts briey 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.
2-22 Features and Controls

OnStar Virtual Advisor
OnStar Virtual Advisor is a feature of
OnStar Hands-Free Calling that uses
minutes to access location-based
weather, local traffic reports, and
stock quotes. Press the phone button
and give a few simple voice
commands to browse through the
various topics. See the OnStar
Owner’s Guide for more information.
This feature is only available in the
continental U.S.
OnStar Steering Wheel
Controls
This vehicle may have a Talk/Mute
button that can be used to
interact with OnStar Hands-Free
Calling. SeeAudio Steering Wheel
Controls on page 3-121for more
information.
On some vehicles, the mute button
can be used to dial numbers into
voice mail systems, or to dial phone
extensions. See the OnStar Owner’s
Guide for more information.
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 service
provider OnStar has hired forthat 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.

they slowly dim after the delay time
until they go out. The delay time is
canceled if the ignition key is turned
to ON/RUN or the power door lock
switch is pressed. The lamps will dim
right away.
When the ignition is on, illuminated
entry is inactive, which means
the courtesy lamps will not come on
unless a door is opened.
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
will continue to work until one of the
following occurs:
The ignition is in ON/RUN.
The doors are locked.
An illumination period of
25 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.
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
will activate and remain 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.
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.
Instrument Panel 3-15

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. See
DIC 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 before the ignition is off.
