Hill Start Assist
The function for assisting when starting the
4
vehicle on inclines (HSA
) helps prevent the
vehicle from rolling backward when starting
on an uphill gradient. When backing up a hill,
HSA helps prevent the vehicle from rolling
forward.
The function retains pressure from the brake
pedal in the brake system for several seconds
after the brake pedal has been released.
This temporary braking effect is released after
a few seconds or when the driver begins driv-
ing.
Hill Start Assist is activated when the vehicle
is stopped on steep inclines. The function is
available even when the Auto-hold brake func-
tion is switched off.

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
Regenerative braking*
The vehicle recovers kinetic energy during
braking in order to reduce fuel consumption
and emissions.
The battery symbol is shown in the
instrument panel when the vehicle is
generating power for the battery
The function is available in all drive modes
together with gear selector 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
if manual gear selector position M is selected.
