STARTING AND DRIVING
450
Foot brake
The foot brake is part of the brake system.
The car is equipped with two brake circuits. If a
brake circuit is damaged, the brake pedal will
engage deeper. Higher pressure on the pedal will
therefore be needed to produce the normal brak-
ing effect.
WARNING
The brake servo only works when the electric
motor or internal combustion engine is run-
ning.
If the foot brake is used when the car is switched
off, greater pedal pressure is required to brake
the car.
In very hilly terrain or when driving with a heavy
load the brakes can be relieved by using engine
braking in gearshift mode
B
.
Use drive mode Off Road for increased engine
braking while driving on steep downhill gradients
at low speeds.
Anti-lock braking system
The car has anti-lock brakes (ABS
2
), which pre-
vents the wheels from locking while braking and
allows maintained steering control. Vibration may
be felt in the brake pedal when this is engaged
and this is normal.
A short test of the ABS system is made automat-
ically after the car has been started when the
driver releases the brake pedal. A further auto-
matic test of the system may be made at low
speed. The test may be felt as pulses in the
brake pedal.
Light braking charges the hybrid battery
The electric motor's engine brake is used during
light braking. The car's kinetic energy is then
converted to electrical energy instead, which is
used to charge the hybrid battery. Battery charg-
ing with electric motor braking is indicated in the
driver display.
The driver display indicates charging during electric
motor braking.
This function is active in the speed interval
150-5 km/h (93-3 mph). During heavier braking,
as well as outside the speed interval, braking is
supplemented by the hydraulic brake system. The
driver's display shows this by the indicator being
down in the red zone.

level is low, fill with brake fluid and
