Driver and front passenger airbags protect
head and chest from impact on the steering
wheel or dashboard in the event of a head-on
collision. The front passenger airbag is equipped
with a seat occupancy detector. The side airbag
(head/upper body) signifi cantly reduces the risk
of injury to the head, ribcage and pelvis area in
the event of a side-on collision.
Adaptive Headlights with variable light
distribution feature moving headlights that
optimise road illumination in bends. This
enhances safety when driving at night or in bad
visibility. Sensors register the steering angle,
yaw rate and vehicle speed, and the direction of
the headlight beams is automatically adjusted
to match the calculated layout of the bend.
Rollover protection system comprises two
steel rollover bars behind the headrests, together
with a high-tensile chassis cross member. The
system also includes a rollover bar of tubular
steel integrated into the windscreen cowl and
A-pillars.
Side impact protection with strengthened
door cross members around the seat and
backrest areas and a seat structure specially
designed for an impact all increase protection
for the occupants.
Bumpers with reversible aluminium impact
absorbers and replaceable deformation
elements at the front and rear absorb impacts
of up to km/h without damage to the body;
energy-absorbing foam in the bumpers
at the front absorbs impacts of up to km/h
without damage.
Cornering Brake Control (CBC) increases
vehicle stability when braking gently in a fast
bend. During braking manoeuvres, the load
on the rear wheels is reduced, which can
lead to oversteering ( ). In brake manoeuvres
that are outside the ABS control range, CBC
addresses this tendency using asymmetric
brake pressure control ( ) in order to create a
stabilising counterforce ( ).
Dynamic Stability Control (DSC) incl. CBC,
Brake Assistant and additional functions.
DSC detects any risk of skidding early on and
stabilises the car in milliseconds. Traction
Mode (DTC) permits increased wheel slip,
in order to maximise propulsion in specifi c
situations and enable a sportier driving style.
In DSC-off mode, an electronic limited slip
differential improves driving characteristics.
Runflat tyres: the reinforced walls mean
that the tyres do not immediately defl ate when
air pressure is reduced, and do not loosen
from the rims.
The runflat indicator comes as standard
and minimises the danger resulting from a tyre
defect. An indicator light on the dashboard
warns the driver of any slight drop in pressure;
an acoustic signal warns of a dramatic drop
in pressure.
Crash sensor overrides the central lock
function in the event of an accident (the doors
can then be opened), the interior lights and
warning blinkers are switched on, and the safety
battery terminal clamp is activated.
