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
(8 km/h).
RABS may be impaired or may not function if a
malfunction has occur red and theye l‐

WARNING Risk of an accident caused by
a malfunction in BAS (Brake Assist Sys‐
te m)
If BA S is malfunctioning, the braking dis tance
in an eme rgency braking situation is
increased.
00BBDepress the brake pedal with full forc e
in emer gency braking situations. ABS
pr eve nts the wheels from locking.

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(8 0 km/h) and
12 5mp h(2 00 km/h) when driving stra ight
ahead or cornering slightly .
RThevehicle is stabilized bymeans of individ‐
ual brake application on one side.

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

Function of Active Brake Assi st
Active Brake Assi stconsist s of:
RDistance warning function
RAu tonomous braking function
RSituation-dependent braking assist ance
RVehicles with Driving Assistance Pack‐
age: Evasi veSteering Assist
Ac tive Brake Assi stcan help youto minimize the
ri sk of a collision with vehicles or pedestrians or
to reduce the ef fects of such a collision.
If Ac 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 and audible colli‐
sion warning, autonomous braking can be initi‐
ated in critical 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 u apply the brake yourself ina critical situa‐
tion or apply the 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 measures for occupant
pr otection (PRE-SAFE
®) may also be initiated, if
th eve hicle is equipped with these.

WARNING Risk of an accident caused by
limited de tection per form ance of Active
Brake Assi st
Ac tive Brake Assi stcannot al ways clearly
identify objects and complex traffic situa‐
tions.
In such cases,Active Brake Assi stmight:
RGive a warning or brake without reason
RNot give a warning or not brake
00BBAlw ays pay careful attention tothe traf‐
fi c situation; do not rely on Active Brake
Assi stalone. Active Brake Assi stis only
an aid. The driver is responsible for
maintaining a sui table dis tance tothe

braking in good time.
00BBBe prepared tobrake or swer veif nec‐

The individual subfunctions are available in
th efo llowing speed ranges:
Distance warning function
The dis tance warning function issues a warning
at speeds:
RFr om appr oximately 4 mph (7 km/h), if your

Sy stem limitations
The sy stem may be impaired or may not function
in thefo llowing situations:
RIn sno w,rain, fog, heavy spr ay, if there is

Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo rth e dis tance totheve hicle in front, forve hi‐
cle speed, for braking in good time and forst ay ‐
ing in lane.
Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out. Change into a lo
werge ar in good time on long
and steep downhill gradients. Take particular
no te ofthis when driving a laden vehicle. By
doing so, you will make use of the braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and
wearin
g tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
RIn traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
ROn slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
