1-22 In Brief
Driver Efficiency Gauge
This gauge assists in driving
efficiently and may vary during
normal operation.
See Driver Efficiency Gauge on
page 5 ‑ 12 for more information.
Automatic Engine
Start/Stop Feature
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 brake
pedal is applied and the vehicle
comes to a complete stop. When
the brake pedal is released, or the
accelerator pedal is applied, the
engine will restart. The engine will
continue to run until the next
auto stop.
To restart the engine during the
auto stop, release the brake pedal
or press the accelerator pedal.
The engine starts immediately.
The vehicle continues to run until
the next stop.
AUTO STOP on the tachometer
signifies that the engine is in auto
stop mode. See
Tachometer on
page 5 ‑ 11 for more information.
A chime will sound when the driver
door is opened while in auto stop
mode. Remember to shift to P (Park)
and turn the ignition to LOCK/OFF
before exiting the vehicle.
See Starting the Engine on
page 9 ‑ 22 .
Regenerative Braking
Regenerative braking takes some of
the energy from the moving vehicle
and turns it into electrical energy.
This energy is then stored in the
vehicle's high voltage battery
system, contributing to increased
fuel efficiency.
The system works whenever the
accelerator pedal is released, and
increases the energy captured as
more brake pedal is applied.
