GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage.
WARNING: Do not park, idle or drive
your vehicle on dry grass or other dry
ground cover. The emission system heats
up the engine compartment and exhaust
system, creating the risk of fire.
WARNING: Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes are toxic. Always
open the garage door before you start the
engine. Failure to follow this instruction
could result in personal injury or death.
WARNING: Exhaust leaks may result
in entry of harmful and potentially lethal
fumes into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 6 mi (10 km)
after you reconnect it. This is because the
engine management system must realign
itself with the engine. You can disregard any
unusual driving characteristics during this
period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the engine.
KEYLESS STARTING
Note:The system may not function if the
remote control is close to metal objects or
electronic devices, for example keys or a
cell phone.
Note:A valid remote control must be located
inside your vehicle to switch the ignition on
and start your vehicle.
Ignition Modes
E144447
The keyless starting system has three
modes:
Off: Turns the ignition off.
205
Starting and Stopping the Engine

• Without applying the brake pedal, press
and release the button once when the
ignition is in the on mode, or when your
vehicle is running but is not moving.
On: All electrical circuits are operational and
the warning lamps and indicators illuminate.
• Without applying the brake pedal, press
and release the button once.
Start: Starts your vehicle. The engine may
not start when your vehicle starts.

the button for any length of time. An
indicator light on the button illuminates
when the ignition is on and when your

STARTING A GASOLINE ENGINE
When you start the engine, the idle speed
increases. This helps to warm up the
engine. If the engine idle speed does not
slow down, have your vehicle checked as
soon as possible.Note: You can crank the engine for a total
of 60 seconds without the engine starting
before the starting system temporarily
disables. The 60 seconds does not have to
be all at once. For example, if you crank the
engine three times for 20 seconds each time,
without the engine starting, you reached the
60-second time limit. A message appears
in the information display alerting you that
you exceeded the cranking time. You
cannot attempt to start the engine for at
least 15 minutes. After 15 minutes, you are
limited to a 15-second engine cranking time.
You need to wait 60 minutes before you can
crank the engine for 60 seconds again.

following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and electrical
accessories are off.
