32 Keys, Doors, and Windows
/(Remote Vehicle Start) :This
button will be on the RKE
transmitter if the vehicle has remote
start.
If equipped, heated and ventilated
front seats may also come on if
enabled in vehicle personalization.
See Heated and Ventilated Front
Seats 057 and Vehicle
Personalization 0145
The climate control system will use
the previous settings during a
remote start. The rear window
defogger may come on during
remote start based on cold ambient
conditions. The rear defog indicator
light does not come on during
remote start.
Laws in some local communities
may restrict the use of remote
starters. For example, some laws
may require a person using remote
start to have the vehicle in view.
Check local regulations for any
requirements.
If your vehicle is low on fuel, do not
use the remote start feature. The
vehicle may run out of fuel. The RKE transmitter range may be
less while the vehicle is running.
Other conditions can affect the
performance of the transmitter. See
Remote Keyless Entry (RKE)
System
027.
Starting the Engine Using Remote
Start
1. Press and release
Qon the
RKE transmitter.
2. Immediately press and hold
/

Steps 1–2 are repeated while the
engine is still running. An extension
can be requested, 30 seconds after
starting. This provides a total of
20 minutes.
The remote start can only be
extended once.
A maximum of two remote starts,
or a remote start with an extension,
are allowed between ignition cycles.
The vehicle's ignition must be
changed to ON/RUN/START and

74 Seats and Restraints
The feature may also activate,
without airbag inflation, after an
event that exceeds a predetermined
threshold. You can lock the doors,
and turn off the interior lamps, and
turn off the hazard warning flashers
by using the controls for those
features.
{Warning
A crash severe enough to inflate
the airbags may have also
damaged important functions in
the vehicle, such as the fuel
system, brake and steering
systems, etc. Even if the vehicle
appears to be drivable after a
moderate crash, there may be
concealed damage that could
make it difficult to safely operate
the vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation. Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.
Airbags are designed to inflate
only once. After an airbag
inflates, you will need some new
parts for the airbag system.
If you do not get them, the
airbag system will not be there
to help protect you in another
crash. A new system will include
airbag modules and possibly
other parts. The service manual
for the vehicle covers the need
to replace other parts.
. The vehicle has a crash sensing
and diagnostic module which
records information after a
crash. See Vehicle Data
Recording and Privacy 0308
and Event Data Recorders
0 308.
. Let only qualified technicians
work on the airbag systems.
Improper service can mean that
an airbag system will not work
properly. See your dealer for
service.
Passenger Sensing
System
The vehicle has a passenger
sensing system for the front
outboard passenger position. The
passenger airbag status indicator
will light on the overhead console
when the vehicle is started.
The symbol for on and off will be
visible during the system check.
When the system check is
complete, either the symbol for on
or off will be visible. See Passenger
Airbag Status Indicator 0118.
The passenger sensing system
turns off the front outboard
passenger frontal airbag and knee
airbag, under certain conditions. No
other airbag is affected by the
passenger sensing system.

110 Instruments and Controls
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.
Some warning lights come on briefly
when the engine is started to
indicate they are working. When
one of the warning lights comes on
and stays on while driving, or when
one of the gauges shows there may
be a problem, check the section that
explains what to do. Waiting to do
repairs can be costly and even
dangerous.

Instruments and Controls 119
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 ever
comes on and stays on, it means
that something may be wrong
with the airbag system. To help
avoid injury to yourself or others,
have the vehicle serviced right
away. SeeAirbag Readiness
Light 0118 for more information,
including important safety
information.
Charging System Light
On some vehicles the charging
system light comes on briefly when
the ignition is turned on, but the
engine is not running, as a check to
show the light is working. It should
go out when the engine is started.
For vehicles with a reconfigurable
cluster, this light may not come on
when the ignition is turned on.
If the light stays on, or comes on
while driving, there may be a
problem with the electrical charging
system. Have it checked by your
dealer. Driving while this light is on
could drain the battery.
When this light comes on, or is
flashing, the Driver Information
Center (DIC) also displays a
message.
See Battery Voltage and Charging
Messages 0135.
If a short distance must be driven
with the light on, be sure to turn off
all accessories, such as the radio
and air conditioner.Malfunction Indicator
Lamp (Check Engine
Light)
This light is part of the vehicle’s
emission control on-board
diagnostic system. If this light is on
while the engine is running, a
malfunction has been detected and
the vehicle may require service. The
light should come on to show that it
is working when the ignition is in
Service Only Mode. See Ignition
Positions 0181.
Malfunctions are often indicated by
the system before any problem is
noticeable. Being aware of the light
and seeking service promptly when
it comes on may prevent damage.

120 Instruments and Controls
Caution
If the vehicle is driven continually
with this light on, the emission
control system may not work as
well, the fuel economy may be
lower, and the vehicle may not
run smoothly. This could lead to
costly repairs that might not be
covered by the vehicle warranty.
Caution
Modifications to the engine,
transmission, exhaust, intake,
or fuel system, or the use of
replacement tires that do not
meet the original tire
specifications, can cause this light
to come on. This could lead to
costly repairs not covered by the
vehicle warranty. This could also
affect the vehicle’s ability to pass
an Emissions Inspection/
Maintenance test. See
Accessories and Modifications
0228. If the light is flashing :
A
malfunction has been detected that
could damage the emission control
system and increase vehicle
emissions. Diagnosis and service
may be required.
To help prevent damage, reduce
vehicle speed and avoid hard
accelerations and uphill grades.
If towing a trailer, reduce the
amount of cargo being hauled as
soon as possible.
If the light continues to flash, find a
safe place to park. Turn the vehicle
off and wait at least 10 seconds
before restarting the engine. If the
light is still flashing, follow the
previous guidelines and see your
dealer for service as soon as
possible.
If the light is on steady : A
malfunction has been detected.
Diagnosis and service may be
required.
Check the following:
. If fuel has been added to the
vehicle using the capless funnel
adapter, make sure that it has been removed. See
“Filling the
Tank with a Portable Gas Can”
under Filling the Tank 0219.
The diagnostic system can
detect if the adapter has been
left installed in the vehicle,
allowing fuel to evaporate into
the atmosphere. A few driving
trips with the adapter removed
may turn off the light.
. Poor fuel quality can cause
inefficient engine operation and
poor driveability, which may go
away once the engine is warmed
up. If this occurs, change the
fuel brand. It may require at
least one full tank of the proper
fuel to turn the light off. See Fuel
0 218.
If the light remains on, see your
dealer.
Emissions Inspection and
Maintenance Programs
If the vehicle requires an Emissions
Inspection/Maintenance test, the
test equipment will likely connect to
the vehicle's Data Link
Connector (DLC).

If the system is working normally,
the indicator light turns off.
If the light is on and not flashing, the
TCS and potentially the StabiliTrak
system have been disabled. A DIC
message may display. Check the
DIC messages to determine which
feature(s) is no longer functioning
and whether the vehicle requires
service.
If the light is on and flashing, the
TCS and/or the StabiliTrak system
is actively working.
