The keyless starting system has three
modes:
Off: Turns the ignition off.
• 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.

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.
Before starting your vehicle, check the
following:
• Make sure all occupants have fastened
their seatbelts.
• Make sure the headlamps and electrical
accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park (P).
• Switch the ignition on.
Note: Do not touch the accelerator pedal.
