TEDama getotheve hicle
In thefo llowing situations, in particular, there
is a risk of damage totheve hicle:
RThe vehicle becomes grounded, e.g. on a
high curb or an unpa vedro ad.
RThe vehicle is driven toofast over an
obs tacle, e.g. a curb, speed bump or pot‐
hole.
RA heavy object strike sth e underbody or
ch assis components.
In situations such as this, the body, the
underbody, chassis components, wheels or
tires could be damaged without the damage
being visible. Components damaged in this
wa ycan unexpec tedly fail or, in the case of
an accident, may not absorb the loads that
arise as intended.
If th e underbody paneling is damaged, flam‐
mable materials such as lea ves, grass or
twigs can collect between the underbody and
th e underbody paneling. These materials may
ignite if they come into contact wi thhot
parts on theex haust sy stem.

Fu nctions of ABS (Anti-lock Brake Sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, e.g. at maximum full-s top
braking or insuf ficient traction of the tires,
th e wheels are pr evented from blocking.
RVehicle steerability while braking is ensured.
If ABS inter venes when braking, youwill feel a
pulsing in the brake pedal. The pulsating brake
pedal can be an indication of hazardous road conditions and can ser
veas a reminder totake
ex tra care while driving.
Sy stem limitations
RABS is active from speeds of appr ox. 5 mph
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐
