212 Driving and Operating
L : This position reduces vehicle
speed without using the brakes. Use
L (Low) on very steep hills, in deep
snow, in mud, or in stop-and-go
traffic.
One-Pedal Driving
With One-Pedal Driving, the
accelerator pedal can be used to
control the deceleration of the
vehicle down to a complete stop.
Completely lifting off the accelerator
pedal will result in aggressive
deceleration. Slowly lifting off the
accelerator pedal will allow the
deceleration of the vehicle to be
adjusted as desired.
To use One-Pedal Driving, place the
vehicle in L (Low). Press the
accelerator pedal to the desired
speed. The deceleration provided by
One-Pedal Driving provides full
regenerative braking and helps
increase energy efficiency. The
brake lamps may come on when the
accelerator pedal is released or
during substantial deceleration from
regenerative braking.
While driving on grades, One-Pedal
Driving may not be able to bring the
vehicle to a complete stop or hold
the vehicle at a stop.
If the vehicle cannot maintain the
grade while using One-Pedal
Driving, the Electric Parking
Brake (EPB) may apply to hold the
vehicle stationary. To drive again,
press the accelerator pedal, and the
EPB will automatically disengage.
One-Pedal Driving may become
disabled and the vehicle may
continue to creep forward, or if
stopped, may apply the EPB or shift
to P (Park). This can be caused by
the following:
The driver door is open.
The driver seat belt is
unbuckled.
The vehicle has remained
stationary for five minutes.
There is a problem with the
propulsion system.
Additional deceleration can be
achieved by using the Regen on
Demand paddle. See Regenerative
Braking 0 215.
