5. Reinstall the battery housing cover
onto the transmitter and install the key
blade.
Car Finder Press the button twice within
three seconds.
The horn sounds and the direction
indicators flash. We recommend you use
this method to locate your vehicle, rather
than using the panic alarm.
Note: If any door or the liftgate is open, or
if the hood is open on vehicles with an
anti-theft alarm or remote start, the horn
will sound twice and the direction indicators
will not flash.
Sounding the Panic Alarm Press the button to sound the
panic alarm. Press the button
again or switch the ignition on to
turn it off.
Note: The panic alarm only operates when
the ignition is off.
Remote Start (If Equipped) WARNING
To avoid exhaust fumes, do not use
remote start if your vehicle is parked
indoors or in areas that are not well
ventilated. Note:
Do not use remote start if your fuel
level is low. The remote start button is on the
transmitter.
This feature allows you to start your
vehicle from the outside. The transmitter
has an extended operating range. Vehicles with automatic climate control
can be configured to operate when the
vehicle is remote started. See Automatic
Climate Control
(page 119).
Many states and provinces have
restrictions for the use of remote start.
Check your local and state or provincial
laws for specific requirements regarding
remote start systems.
The remote start system does not work if
any of the following occur:
• The ignition is on.
• The anti-theft alarm triggers.
• You switch off the feature.
• The hood is open.
• The transmission is not in park (P).
• The battery voltage is below the
minimum operating voltage.
• The service engine soon indicator was
on the last time your vehicle was
driven.
Remote Starting Your Vehicle
Note: You must press each button within
three seconds of each other. If you do not
follow this sequence, your vehicle does not
start remotely, the direction indicators do
not flash twice and the horn does not sound. The label on your transmitter details the
starting procedure.
To start your vehicle remotely:
1. Press the lock button to lock all the
doors.

Powertrain Malfunction/Reduced
Power
Illuminates when a powertrain
or an AWD fault has been
detected. Contact your
authorized dealer as soon as possible.
Service Engine Soon If the service engine soon
indicator light stays illuminated
after the engine is started, it
indicates that the On Board Diagnostics
system (OBD) has detected a malfunction
of the vehicle emissions control system.
Refer to On board diagnostics (OBD) in
the Fuel and Refueling chapter for more
information about having your vehicle
serviced. See Emission Control System
(page 161).
If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic
converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have an authorized
dealer service your vehicle immediately. The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing. Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See
Emission Control
System (page 161).
Stability Control It will flash when the system is
active. If it remains illuminated
or does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction the
system will switch off. Have the system
checked by your authorized dealer
immediately. See
Using Stability
Control (page 179).
Stability Control Off It will illuminate when you switch
the system off. It will go out
when you switch the system
back on or when you switch the ignition
off. See
Using Stability Control (page
179).
Directional Indicator Illuminates when you switch on
the left or right or the hazard
warning flasher. If the indicators
stay on or flash faster, check for a burned
out bulb. See Changing a Bulb (page 260).
