Regenerative Braking System
This feature is used to simulate the
engine braking of an internal
combustion engine and assist the
standard brake system while
recovering some of the energy of
motion and storing it in the battery to
improve fuel economy. The standard
brake system is designed to fully stop
the car if regenerative braking is not
available. During regenerative braking,
the motor is spun as a generator to
create electrical current. This
recharges the battery and slows the
vehicle. In effect, once the accelerator
pedal is released, the motor changes
from an energy user to an energy
producer.
When you release the accelerator
pedal or press the brake pedal, the
brake controller automatically detects
the amount of deceleration requested
and optimizes how much of the
deceleration will be produced by
regenerative braking. The remaining
portion is generated by standard
friction braking. When the battery is
almost fully charged, the amount of
regenerative braking is limited to avoid
overcharging, and the requested
deceleration is produced by standard
friction braking alone.
Regenerative braking does not take
the place of the standard friction
brakes; it only assists them.
Regenerative braking has also been
designed to interact with the anti-lock
brake system. Regenerative braking
is disabled when the anti-lock brake
system is activated or the battery is
fully charged.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating,
the brake pedal will pulse and may
travel further. Maintain pressure on the
brake pedal. You may also hear a noise
from the system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• you drive too closely to the vehicle
in front of you
• your vehicle is hydroplaning
• you take corners too fast
• the road surface is poor.
ELECTRIC PARKING BRAKE
The electric parking brake replaces
the conventional handbrake. The
operating switch is located on the
instrument panel to the left of the
steering wheel.
WARNING
Always set the parking brake and
leave your vehicle with the
transmission selector in position P.
Note: When you apply the electric
parking brake in certain conditions, for
example on a steep hill, the electric
parking brake may reapply the brakes
within three to ten minutes.
Note: You may notice various noises
when you apply and release the electric
parking brake. This is normal and no
cause for concern.
