ing vehicle settings while theve hicle is in
motion
Yo u could lose cont rol of theve hicle in the
fo llowing situations:
R ifyo u adjust the driver's seat, the head
re stra ints, thesteering wheel or the mir‐
ro r while theve hicle is in motion
R ifyo ufast enyour seat belt while theve hi‐

Before starting the engine: adjust the
driver's seat, the head restra ints, the
st eering wheel or the mir ror and fasten
yo ur seat belt. &
WARNING Risk of accident due tomis‐
judgement of dis tances when using the
outside mir ror
The outside mir rors reflect objects on a
smaller scale. The objects in view are in fact
closer than they appear.
As a result, you may misjud gethe dis tance
between you and thero ad user driving
behind you, e.g. when changing lanes. #
Therefore, alw ays look over your shoul‐
der in order toensure that you are
aw are of the actual dis tance between
yo u and thero ad users driving behind
yo u. #

The engine is switched off au tomatically in the
fo llowing situations if all vehicle conditions for
an automatic engine stop are me t:

engine will automatically stop in thefo llowing
situations:
R youstop behind a vehicle that is pulling

st eering wheel gearshift paddle. If permit ted, the
automatic transmission shifts tothe next gear

Fu

fety sy stems use
ra dar sensors tomonitor the area in front of,
behind or next totheve hicle (depending on the
ve hicle's equipment).
Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. Keep these
parts free of dirt, ice and slush
(/ page442). The sensors must not be cov‐
ered, forex ample bycycle rack s, overhanging
loads, sticke rs,fo il or foils toprotect against
st one chipping. In theeve nt of dama getothe
bumpers or radiator grille, or following a collision
impacting the bumpers or radiator grille, ha ve
th e function of thera dar sensors checked at a
