How To Use Remote Start
All of the following conditions must be met before the engine
will remote start:
• Gear selector in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Battery at an acceptable charge level
• PANIC button not pushed
• Fuel meets minimum requirement

WARNING!
• Do not start or run an engine in a closed garage or confined area. Exhaust gas contains Carbon Monoxide
(CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury or
death when inhaled.
• Keep key fobs away from children. Operation of the Remote Start System, windows, door locks or other
controls could cause serious injury or death.

Push and release the Remote Start button on the key
fob twice within five seconds. The parking lights
will flash, vehicle doors will lock, and the horn will
chirp twice (if programmed). Once the vehicle has started,
the engine will run for 15 minutes.

• If your power door locks were unlocked, Remote Start will automatically lock the doors.
• If an engine fault is present or fuel level is low, the vehicle will start and then shut down in 10 seconds.
• The park lamps will turn on and remain on during Remote Start mode.
• For security, power window and power sunroof operation (if equipped) are disabled when the vehicle is in the
Remote Start mode.
• The engine can be started two consecutive times (two 15-minute cycles) with the key fob. However, the ignition
must be placed in the ON/RUN position before you can
repeat the start sequence for a third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the remote start button one time or allow
the engine to run for the entire 15-minute cycle.
NOTE:
To avoid unintentional shutdowns, the system will disable
with a one time push of the remote start button for two
seconds after receiving a valid remote start request.
To Exit Remote Start Mode And Drive The Vehicle
Before the end of the 15-minute cycle, push and release the
unlock button on the key fob to unlock the doors and disarm
the vehicle security alarm system (if equipped). Then, prior
to the end of the 15-minute cycle, cycle the ignition to the
ON/RUN position.

Remote Start Comfort System operation.
General Information
The following regulatory statement applies to all radio
frequency (RF) devices equipped in this vehicle:
This device complies with Part 15 of the FCC Rules and with
Industry Canada license-exempt RSS standard(s). Operation
is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesired opera -
tion.
NOTE:
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition and
a RF receiver to prevent unauthorized vehicle operation.
Therefore, only key fobs that are programmed to the vehicle
can be used to start and operate the vehicle. The system
cannot reprogram a key fob obtained from another vehicle.
After turning the ignition switch to the ON/RUN position,
the vehicle security light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In addi -
tion, if the light begins to flash after the bulb check, it indi -
cates that someone attempted to start the engine with an
invalid key fob. In the event that a valid key fob is used to
start the engine but there is an issue with the vehicle elec -
tronics, the engine will start and shut off after two seconds.
