If the system is disabled,
normal braking is still
effective. If the brake
warning lamp illuminates with the
parking brake released, have your
brake system serviced immediately.
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 the accelerator pedal is
released or the brake pedal is applied,
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 ABS 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 lever in position
