Note:
Your vehicle has a battery saver
feature that shuts your vehicle off when it
detects a certain amount of battery drain, or
after approximately 30 minutes of inactivity
in accessory mode.
Starting the Engine
With the transmission in park (P), press the
brake pedal and press the push button
ignition switch. An indicator light on the
button illuminates when the ignition is on
and when the engine starts.
Note: The system may not function if the
passive key is close to metal objects or
electronic devices, for example keys or a
cell phone.
Note: A valid key must be inside your vehicle
to switch the ignition on and start the engine. STARTING THE ENGINE
Starting a Gasoline Engine
Before starting your vehicle, check the
following:
•
Make sure that the headlamps and
electrical accessories are off.
• Make sure that the parking brake is on.
• Make sure that the transmission is in park
(P).
1. Fully press the brake pedal.
Note: Do not touch the accelerator pedal. 2. Press the push button ignition switch.
Note:
The engine may continue cranking for
up to 15 seconds or until it starts.
Note: The engine takes longer to start at
lower temperatures. It may crank for several
seconds when very cold. Restarting the Engine After Stopping
it
The system allows you to start the engine
within 10 seconds of switching it off, even if
it does not detect a valid passive key.
Within 10 seconds of switching the engine
off, fully press the brake pedal and press the
push button ignition switch. After 10 seconds,
you can no longer start the engine if the
system does not detect a valid passive key.
When you start the engine, it remains running
until you press the push button ignition
switch, even if your vehicle does not detect
a valid passive key. If you open and close a
door when the engine is running, the system
searches for a valid passive key.

ENGINE BLOCK HEATER (If Equipped)
Engine Block Heater Precautions
WARNING: Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
Do not fully close the
hood, or allow it to drop under its own
weight when using the engine block
heater. This could damage the power cable
and may cause an electrical short resulting
in fire, injury and property damage. We recommend that you do the following for
a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by Underwriter’ s
Laboratory (UL) or Canadian Standards
Association (CSA). This extension cord
must be suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and engine block
heater cord plug connections are free
and clear of water. This could cause an
electric shock or fire.
• If the engine block heater cord is under
the hood, do not remove the wiring from
its original location. Do not close the
hood on the extension wiring. •
Park your vehicle in a clean area, clear
of combustible materials.
• Firmly connect the engine block heater
cord and the extension cord.
• Check the extension cord for heat
anywhere when the system has been
operating for approximately 30 minutes.
• Unplug and properly stow the system
before starting and driving your vehicle.
The protective cover seals the terminals
of the engine block heater cord plug
when not in use.
• Check the engine block heater system
for proper operation before winter.
How Does the Engine Block Heater
Work
The engine block heater warms the engine
coolant. This allows the climate control
system to quickly respond. The equipment
includes a heater element installed in the
engine block and a wire harness. You can
connect the system to a grounded 220-240
volt AC electrical source.

2. With the buttons facing upward and the
unlock button facing the front of your
vehicle, place the passive key into the

and start your vehicle. STARTING AND STOPPING THE
ENGINE – TROUBLESHOOTING
Starting and Stopping the Engine –
Warning Lamps
Malfunction Indicator Lamp If it illuminates when the engine is
running, the on-board diagnostics
system is detecting a malfunction
of the vehicle emission control system.
If it flashes, engine misfire could be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Avoid heavy acceleration and deceleration,
and have your vehicle checked as soon as
possible. Powertrain Warning Lamp If it illuminates when the engine is
running, this indicates a powertrain
or four-wheel drive fault. If it
flashes when you are driving, immediately
reduce the vehicle speed. Avoid heavy
acceleration and deceleration, and have your
vehicle checked as soon as possible.
If both lamps illuminate when the engine is
running, stop your vehicle as soon as it is
safe to do so. Continuing to drive your
vehicle could cause reduced power or the
engine to stop. Switch the ignition off and
attempt to restart the engine. Have your
vehicle checked as soon as possible.
