Remote Start (If Equipped)
WARNING:To avoid exhaust fumes, do not use remote start if
your vehicle is parked indoors or areas that are not well
ventilated.
Note: Do not use remote start if your vehicle is low on fuel.
The remote start button is on the transmitter.
This feature allows you to start your vehicle from outside your vehicle.
The transmitter has an extended operating range.
Vehicles with automatic climate control can be configured to operate
when the vehicle is remote started. See the Climate Controlchapter for
more information. A manual climate control system will run at the setting
it was set to when your vehicle was last turned off.
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 will not work if:
• the ignition is on
• the alarm system is triggered
• you disable the feature
• the hood is open
• the transmission is not in P
• the vehicle battery voltage is too low
• the service engine soon light is on.
Remote Starting the Vehicle
Note: You must press each button within three seconds of each other.
Your vehicle will not remote start and the horn will not sound if you do
not follow this sequence.

driving, this indicates a malfunction. Stop your vehicle as soon
as it is safe to do so and switch the engine off. Check the
engine oil level.
Note: Do not resume your journey if it illuminates despite the level
being correct. Have the system checked by your authorized dealer.

your safety belt.

remains on with the engine running or when driving, check
your tire pressure as soon as possible.
The lamp also illuminates momentarily when you switch the ignition on
to confirm the lamp is functional. If it does not illuminate when you
switch the ignition on, or begins to flash at any time, have the system
checked by an authorized dealer. Refer to Wheels and Tiresfor more
information.
Low Washer Fluid
It will illuminate when the windshield washer fluid is low.
Parking Lamps It will illuminate when you switch the parking lamps on.
Powertrain Fault Illuminates when a powertrain fault has been detected. Contact
your authorized dealer as soon as possible.
Service Engine Soon Theservice engine soon indicator light illuminates when the
ignition is first turned to the on position 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 the Readiness for inspection/maintenance
(I/M) testing in theFuel and Refueling chapter.
Solid illumination after the engine is started indicates the on-board
diagnostics system (OBD-II) has detected a malfunction. Refer to
On-board diagnostics (OBD-II) in theFuel and Refueling chapter. 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 by your
authorized dealer.
