Start/Stop

WARNING
Exiting the vehicle, without first
shifting into P (Park), may cause
the vehicle to move, you or others
may be injured. Because the
vehicle has the automatic engine
start/stop feature, the vehicle's
engine might seem to be shut off;
however, once the brake pedal is
released, the engine will start up
again.
Shift to P (Park) and turn the
ignition to LOCK/OFF, before
exiting the vehicle.
Vehicles with eAssist have an
automatic engine start/stop feature.
After the engine is started and has
reached operating temperature, the
auto stop feature may cause the
engine to turn off when the brakes
are applied and the vehicle comes
to a complete stop. The vehicle
may remain in auto stop for up to
two minutes. When the brake is
released or the accelerator pedal is
applied, the engine will start. The
engine will continue to run until the
next auto stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See Tachometer on
page 5�11 for more information.
When the vehicle is turned off, the
tachometer will move to OFF. If the
driver door is opened while in auto
stop mode, a chime will sound.
To restart the engine during auto
stop, release the brake pedal or
press the accelerator pedal. The
engine starts immediately. The
vehicle continues to run until the
next stop.
There are several conditions which
may prevent an auto stop or cause
an auto start.
