Braking assist after a collision
In a collision in which the activation level is
reached for the pyrotechnic seat belt tension-
ers or airbags, or if a collision with a large ani-
mal is detected, the vehicle's brakes will be
automatically activated. This function is
intended to help prevent or reduce the effects
of any subsequent collision.
After a serious collision, it may no longer be
possible to control and steer the vehicle. In
order to avoid or mitigate a possible further
collision with a vehicle or an object in the vehi-
cle's path, the brake assist system is activated
automatically to help stop the vehicle safely.
If braking is not appropriate, e.g. if there is a
risk of being hit by passing traffic, the driver
can override the system by depressing the
accelerator pedal.
This function assumes that the brake system
is intact after a collision.

Transmission
The transmission is part of the vehicle's drive-
line (power transmission) between the engine
and the drive wheels. The function of the
transmission is to change gears depending
on speed and power needs.
The vehicle has an 8-speed automatic trans-
mission. The number of gears allows the
engine's torque and power band to be effec-
tively utilized. Two of the gears are overdrive
gears that save fuel when driving at a constant
engine speed. Manual shifting is also possible.
The instrument panel shows the gear currently
in use.

STARTING AND DRIVING
Automatic transmission
In vehicles with an automatic transmission,
the system selects the gear so that driving
will be as energy-efficient as possible. The
transmission also has a manual mode.
The transmission is available in different ver-
sions. The gear selector indicates which trans-
mission the vehicle has. The various gear
selectors have different functions.
