The pa rking lights, low beam and daytime run‐
ning la mps are switched on or off automatically
depending on the ignition status, whe ther the
engine is running and on the ambient light.

WARNING Risk of accident when the low
beam is switched off in poor visibility
When the light switch is set toÃ, the low
beam may not be switched on automatically
if th ere is fog, snow or other causes of poor
visibility such as spr ay.
#In such cases, turn the light switch to
L.

WARNING Risk of accident despite
Ad aptive Highbeam Assist
Ad aptive Highbeam Assist does not recog‐
nize thefo llowing road users:
RRo ad users without lights, e.g. pedes‐
trians
RRo ad users with poor lighting, e.g.
cyclists
RRo ad users whose lighting is obstructed,
e.g. bya bar rier
On very rare occasions, Adaptive Highbeam
Assist may failto recognize other road users
with their own lighting, or may recognize
th em too late.
In these or similar situations, the automatic
high beam is not deactivated or is activated
despite the presence of other road users.
#Alw ays obser vethe tra ffic carefully and
switch off the high beam in good time.
Ad aptive Highbeam Assist switch es automati‐
cally between:

At speeds abo ve19 mp h (30 km/h):
RIf no other road users are de tected, the high

Fu nctions of ABS (anti-lock braking sy stem)
ABS regulates the brake pressure in critical driv‐
ing situations:
RDuring braking, the wheels are pr evented
from blocking, e.g. due tomaximum full-s top
braking or insuf ficient traction of the tires.
RVe hicle 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

WARNING Risk of skidding if ESP®is
malfunctioning
If ESP
®is malfunctioning, ESP®cannot car ry

#Drive on carefull y.
#Have ESP®checked at a qualified spe‐
cialist workshop.

WARNING Risk of skidding if ESP®is
deactivated
If yo u deactivate ESP
®, ESP®cannot car ry

#ESP®should only be deactivated in the
fo llowing situations.
ESP®monitors and impr oves driving stability and
traction, particular ly inthefo llowing situations:
RWhen pulling away on wet or slippe ryroads.
RWhen braking.
RIn stro ng sidewinds when you are driving
fast erthan 50 mph (80 km/h).
ESP
®can stabilize theve hicle byinter vening in
th efo llowing ways:
ROne or more wheels are braked.
RThe engine output is adap ted according to
th e situation.
ESP
®is deactivated if the ESP®OFF å warn‐
ing lamp lights up continuously in the instrument
clus ter:
RDriving stability will no longe r be improved.
RCrosswind Assist is no longer active.
RThe drive wheels could spin.
RETS/4ETS traction control is still active.

Rwhen using snow chains
Rin deep snow
Ron sand or gr avel
% Spinning the wheels results in a cutting

Fu nctions of ESP®Crosswind Assist
ESP®Crosswind Assist de tects sudden gust s of
side wind and helps the driver tokeep theve hi‐
cle in the lane:
RESP®Crosswind Assist is active at vehicle
speeds between 50 mph (80 km/h) and
12 5mp h (200 km/h) when driving stra ight
ahead or cornering slightly.
RThe vehicle is stabilized bymeans of individ‐
ual brake application on one side.
Fu nction of EBD (Electronic Brake forc e Dis‐

EBD is characterized bythefo llowing:
RMonitoring and regulating the brake pressure
on there ar wheels.
RImpr oved driving stability when braking,
especially on bends.

IfAc tive Brake Assi sthas de tected a risk of colli‐
sion, youwill be warned visually and acousti‐
cally.
If yo udo not react tothe visual or acoustic warn‐
ing, autonomous braking can be initiated in criti‐
cal situations.
In especially critical situations, Active Brake
Assi stcan initiate autonomous braking direct ly.
In this case, the visual and acoustic warning
occurs simultaneously with the braking applica‐
tion.
If yo uappl yth e brake yourself ina critical situa‐
tion or applyth e brake during autonomous brak‐
ing, situation-dependent braking assis tance
occurs . This increases the brake pressure up to
maximum full-s top braking if necessar y.
If th e autonomous braking function or the situa‐
tion-dependent braking assis tance is trig gered,
additional pr eventive measure sfo r occupant pr
otection (PRE-SAFE®) may also be initiated, if
th eve hicle is equipped with these.

In such cases,Active Brake Assi stmight:
Rgive an unnecessa rywa rning or brake the

The dis tance warning function issues a warning
at speeds:
RFr om appr oximately 4 mph (7 km/h), if your
