Starting the Vehicle
WARNING
Exiting the vehicle, without first
shifting into P (Park), may cause
the vehicle to move, and you or
others can be seriously injured.
Because the vehicle has the
Automatic Engine Start/Stop
feature, the vehicle s engine
might seem to be shut off when
you come to a complete stop.
However, once the brake pedal is
released, the vehicle can move.
The vehicle s engine can also
restart at any time.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
Start the engine as you would any
other engine. See Starting the
Engine in the owner manual for
more information on starting.
If pulling a trailer with trailer brakes,
see Towing Equipment on
page 9 17 for more information.
Auto Stop
The vehicle has an Auto Stop
feature. After a successful engine
start, the engine may turn off and
operate in the Auto Stop mode.
Some of the vehicle conditions that
allow the engine to stop running and
enter the Auto Stop mode are:
Ignition switch is in the
ON/RUN position.
The hood is closed.
The gear selector is in P (Park),
R (Reverse), N (Neutral) or
D (Drive).
The hybrid battery is at an
acceptable state of charge.
Black plate (2,1)
The hybrid battery voltage,
temperature or power limits are
not exceeded. In very hot
conditions, Auto Stop may be
unavailable until the hybrid
battery has cooled.
The engine is at operating
temperature.
The vehicle may enter Auto Stop
after a remote vehicle start.
With your foot off the brake and the
vehicle on level ground, the hybrid
drive motor may cause the vehicle
to roll slowly forward, even when the
engine is in Auto Stop.
Keep your foot firmly on the brake
pedal until you are ready for the
vehicle to move.
Engine OFF and AUTO STOP
modes are indicated on the
tachometer display. When the
tachometer needle indicates OFF,
the engine is not running and will
remain off until the ignition key is
placed in the START position or a
remote vehicle start is performed.
