Auto braking after a collision
In the event of a collision in which the activa-
tion level is reached for the pyrotechnic seat-
belt tensioners or airbags, or if a collision
with a large animal is detected, the car's
brakes are automatically applied. This func-
tion is to prevent or reduce the effects of any
subsequent collision.
After a serious collision there is a risk that it is
no longer possible to control and steer the car.
In order to avoid or mitigate a possible further
collision with a vehicle or an object in the vehi-
cle's path, the auto braking system is acti-
vated automatically and brakes the car in a
safe manner.
Brake lights and hazard warning lights are
activated during braking. When the car has
stopped, the hazard warning lights continue to
flash and the parking brake is applied.
If braking is not appropriate, e.g. if there is a
risk of being hit by following traffic, the sys-
tem can be overridden by the driver depress-
ing the accelerator pedal.
The function assumes that the brake system is
intact after the collision.

Regenerative braking*
The car recovers kinetic energy during brak-
ing in order to reduce fuel consumption and
emissions.
The battery symbol is shown in the
driver display when the car is gener-
ating power for the battery
The function is available in all drive modes
together with gear position D or M.
Activating brake regeneration
Brake regeneration is activated by gentle pres-
sure on the brake pedal or during engine brak-
ing.
Regeneration increases during engine braking
when manual gearshift mode M is selected.

Gearbox
The gearbox is part of the car's powertrain
(power transmission) between engine and
drive wheels. The function of the gearbox is
to change the gear ratio depending on speed
and power requirements.

There are two main types of gearbox, manual
.
and automatic.
The manual gearbox has six gears and the
automatic gearbox has eight. The number of
gear changes means that the engine's torque
and power range can be used effectively. In
the automatic gearbox, two of the gears are
overdrive gears that save fuel when driving at
constant engine speed.
It is also possible to select gears manually
with the automatic gearbox. The driver display
shows the selected gear position.
