Glide mode function
Wi th an anticipatory driving style, glide mode
helps youto reduce fuel consum ption.
Glide mode is characterized bythefo llowing:
RThe combustion engine is disconnected from

RThe transmission position 005Bis displa yed in
green in the multifunction displa y.
Glide mode is activated if thefo llowing condi‐

Driving and driving saf ety sy stems
Driving sy stems and your responsibility
Yo ur vehicle is equipped with driving sy stems
which assist youin dr iving, parking and maneu‐
ve ring theve hicle. The driving sy stems are tools
and do not relie ve you of your responsibility. Pay
attention tothe tra ffic conditions at all times
and inter vene when necessary . Beaware of the
limitations rega rding the safe use of these sys‐
te ms.
Fu nction of thera dar senso rs
Some driving and driving safe ty systems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle&#39;s equipment).
Depending on theve hicle&#39;s equipment, thera dar
sensors are integrated behind the bumpers
and/or behind thera diator grille. Keep these
parts free of dirt, ice and slush (
→page 327).
The sensors must not be co vered, forex ample
by bicycle rack s, ove rhanging loads or radar-
re flecting sticke rs.Fo llowing an impact and in
th eeve nt of associated damage , which may not
be visible, tothe bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
qu alified specialist workshop. The driver assis‐
ta nce sy stem may no longer workproperly.

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, you will 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
