Auto braking after a collision
In the event of a collision in which the activation
level is reached for the pyrotechnic seatbelt ten-
sioners or airbags, or if a collision with a large
animal is detected, the car's brakes are automat-
ically applied. This function 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 colli-
sion with a vehicle or an object in the vehicle's
path, the auto braking system is activated auto-
matically and brakes the car in a safe manner.
Brake lights and hazard warning lights are acti-
vated 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 system can be
overridden by the driver depressing the accelera-
tor pedal.
The function assumes that the brake system is
intact after the collision.
Brake assist is included in the Rear Collision
Warning and Blind Spot Information safety sys-
tems.

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 auto-
matic gearbox has eight. The number of gear
changes means that the engine's torque and
power range can be used effectively. In the auto-
matic 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 respec-
tively shows which gear or gear position is cur-
rently in use.
IMPORTANT
To prevent damage to any drive system com-
ponents, the working temperature of the
gearbox is checked. If there is a risk of over-
heating, a warning symbol illuminates in the
driver display and a text message is shown -
follow the recommendation given.
