tings are adjus ted while theve hicle is in
motion
Yo u could lose cont rol of theve hicle in par‐
ticular in thefo 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, head restra ints, steering
wheel and mir ror in particular and fas‐
te nyo ur seat belt. &

judgement of dis tance 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. #
Therefore, alw ays look over your shoul‐

WARNING Risk of accident and inju ry
due toleaving children unat tended in the

R in cer tain driving and driving saf ety sy stems,
th e sensors adjust automatically while a cer‐
ta in dis tance is being driven af terth eve hicle

pensate forth ere duced braking ef fect by
applying greater forc eto the brake pedal. Note
s on optimised acceleration If all necessary
requirements and activation con‐
ditions are fulfilled, the best possible accelera‐
tion can be achie ved from a standstill.
Do not use the optimised acceleration on public
ro ads. Individual wheels could spin and youcould lose control of
theve hicle. There is an
increased risk of skidding and/or accident.
Be sure toobser vethe saf ety no tes and informa‐
tion on ESP ®

WARNING Risk of skidding and having
an accident from wheels spinning
When you use optimised acceleration, indi‐
vidual wheels could spin and you could lose
cont rol of theve hicle.
If ESP ®
is deactivated, there is a risk of skid‐
ding and accident! #
Make sure that no persons or obstacles
are in the close vicinity of your vehicle. Re

s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerably orresult in braking only on one
side
R maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey Note
s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page410).
Note s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage. Obser
vethefo llowing if you must drive thro ugh
wate r:
R The water,when calm, may only reach the
lo we r edge of theve hicle body.
R Drive at a maximum speed of 10km/h;
wate r can otherwise enter theve hicle interior
or engine compartment.
R Vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible dep thofthewate r.
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention to
th e tra ffic conditions until braking po wer has
been fully restored. ECO

The engine is switched off automatically in
the
fo llowing situations if all vehicle conditions for
an automatic engine stop are me t:
R You brake theve hicle toast andstill in trans‐
mission position hori.
R Vehicles with a 48 V on-board electrical
sy stem: You depress the brake pedal when
tra velling at a low speed.
If th e sy stem has de tected one of thefo llowing
situations, the engine will not stop:
R Youstop at a stop sign and there is no vehi‐
cle in front of you.
R The vehicle that stopped in front of you
st arts up again.
R You manoeuv re, turn thesteering wheel
sharply or engage reve rsege ar.
% Ifth e sy stem de tects an intellige ntstop
inhibitor, forex ample, a stop sign, the engine
will not stop.
If yo u activate the HOLD function or engage
th e park position j,the engine can be
switched off in spite of an intelligent stop
inhibitor. The engine is
restar ted automatically if:
R You en gage transmission position hork.
R You depress the accelerator pedal.
R An automatic engine start is requiredbythe
ve hicle.
R Youre lease the brake pedal.
R Vehicles with a 48 V on-board electrical
sy stem:
- Youre lease the brake pedal on a downhill
gradient and theve hicle does not roll.
- The vehicle rolls on a downhill gradient
and does not automatically enter glide
mode at 20 km/h.
ECO start/ stop function symbols in the multi‐
function display:
R The symbol è(green) appears when the
ve hicle is at a standstill: the engine was
switched off bythe ECO start/ stop function.
R The symbol ç(yellow) appears when the
ve hicle is at a standstill: not all vehicle condi‐
tions for an engine stop ha vebeen met. R
Neither the symbol ènorç appears
when theve hicle is at a standstill: an intelli‐

stem (ABS) regulates the
brake pressure in critical driving situations:
R During braking, e.g. at full brake application
or insuf ficient tyre traction, the wheels are
pr eve nted from lock ing.
R Vehicle 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. Fu
