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.

STARTING AND DRIVING
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.
5 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.
Both the gear selector and the steering wheel
paddles can be used to shift up or down man-
ually. The selected gear selector position will
be displayed in the instrument panel.
