the front-passenger seat to the shoulder belt
guide on the child restraint system. The shoul-
der belt strap must be routed forwards from the
retracted seat-belt extender for the front-
passenger seat.
Always observe the child restraint system man-
ufacturer's installation and operating instruc-
tions.
Pets in the vehicle
GWARNING
If you leave animals unattended or unsecured
in the vehicle, they could press buttons or
switches, for example.
As a result, they could:
Ractivate vehicle equipment and become
trapped, for example
Ractivate or deactivate systems, thereby
endangering other road users
Unsecured animals could also be flung around
the vehicle in the event of an accident or sud-
den steering or braking, thereby injuring vehi-
cle occupants. There is a risk of an accident
and injury.
Never leave animals unattended in the vehi-
cle. Always secure animals properly during
the journey, e.g. use a suitable animal trans-
port box.
Driving safety systems
Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS ( Anti-lock Braking System)
(Ypage 61)
RBAS ( Brake Assist System) (Ypage 62)
RBAS PLUS ( BrakeAssist System PLUS) with
Cross-Traffic Assist (Ypage 62)
RCOLLISION PREVENTION ASSIST PLUS
(Ypage 64)
RESP®( E lectronic StabilityProgram)
(Ypage 66)
REBD ( Electronic Brake force Distribution)
(Ypage 68)
RADAPTIVE BRAKE (Ypage 68)
RPRE-SAFE®Brake (Ypage 68)
RSTEER CONTROL (Ypage 70)
Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override
the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described only work as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section (
Ypage 302).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information
ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The ! ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from a speed of about 5 mph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Driving safety systems61
Safety
Z

Crosswind Assist
General information
Strong crosswind gusts can impair the ability of
your vehicle to drive straight ahead. The cross-
wind driving assistance function integrated in
ESP
®noticeably reduces these impairments.
ESP®intervenes automatically according to the
direction and intensity of the crosswinds affect- ing your vehicle.
ESP
®intervenes with stabilizing braking to
assist you in keeping the vehicle in the lane.
Crosswind Assist is active at vehicle speeds
above 50 mph (80 km/h)when driving straight
ahead or cornering gently.
Important safety notes
Crosswind Assist does not work if ESP®is
switched off or deactivated because of a mal-
function.
EBD (electronic brake force distribu-
tion)
General information
EBD monitors and controls the brake pressure
on the rear wheels to improve driving stability
while braking.
Important safety notes
iObserve the "Important safety notes" sec-
tion (Ypage 61).
GWARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
Observe information regarding indicator and
warning lamps (
Ypage 235) as well as display
messages (Ypage 207).
ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety and
offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has
the HOLD function (
Ypage 158) and hill start
assist (Ypage 127).
PRE-SAFE®Brake
General information
PRE-SAFE®Brake can help you to minimize the
risk of a collision with a vehicle ahead or a
pedestrian, and reduce the effects of such a
collision. If PRE-SAFE
®Brake has detected a risk
of collision, you will be warned visually and
acoustically as well as by automatic braking.
iPay attention to the important safety notes
in the "Driving safety systems" section
(
Ypage 61).
PRE ‑SAFE
®Brake is only available in vehicles
with the Driving Assistance Plus package.
For PRE-SAFE
®Brake to assist you when driving,
the radar sensor system and the camera system
must be switched on and be operational.
With the help of the radar sensor system and the
camera system, PRE-SAFE
®Brake can detect
obstacles that are in front of your vehicle for an
extended period of time.
In addition, pedestrians in the path of your vehi-
cle can be detected.
PRE-SAFE
®Brake detects pedestrians using
typical characteristics such as the body con-
tours and posture of a person standing upright.
iObserve the restrictions described in the
"Important safety notes" section
(
Ypage 68).
Important safety notes
GWARNING
PRE-SAFE
®Brake will initially brake your vehi-
cle by a partial application of the brakes if a
danger of collision is detected. There may be
a collision unless you brake yourself. Even
after subsequent full application of the brakes
a collision cannot always be avoided, partic-

Rthere is interference by other radar sources
Rthere are strong radar reflections, for exam-
ple, in parking garages
If DISTRONIC PLUS no longer detects a vehicle
in front, DISTRONIC PLUS may unexpectedly
accelerate the vehicle to the stored speed.
This speed may:
Rbe too high if you are driving in a filter lane or an exit lane
Rbe so high in the right lane that you pass vehi-cles driving on the left (left-hand drive coun-
tries)
Rbe so high in the left lane that you pass vehi-
cles driving on the right (right-hand drive
countries)
If there is a change of drivers, advise the new
driver of the speed stored.

Activating DISTRONIC PLUS
Activation conditions
To activate DISTRONIC PLUS, the following con-
ditions must be fulfilled:
Rthe engine must be started. It may take up to two minutes after pulling away before
DISTRONIC PLUS is operational.
Rthe electric parking brake must be released.
RESP®must be activated, but not intervening
at present.
RActive Parking Assist must not be activated.
Rthe transmission must be in position D.
Rthe driver's door must be closed when you
shift the transmission from Pto Dor your seat
belt must be fastened.
Rthe front-passenger door and rear doors must
be closed.
Activating
XBriefly pull the cruise control lever towards
you ?, up :or down ;.
DISTRONIC PLUS is activated.
XTo adjust the set speed in1 mphincre-
ments (1 km/hincremen ts):briefly press
the cruise control lever up :to the pressure
point for a higher speed, or down ;for a
lower speed.
Every time the cruise control lever is pressed up or down, the last speed stored is increased
or reduced.
or
XTo adjust the set speed in5 mphincre-
ments (10 km/hincrements):briefly press
the cruise control lever up :past the pres-
sure point for a higher spee
d, or down;for
a lower speed.
Every time the cruise control lever is pressed
up or down, the last speed stored is increased
or reduced.
XRemove your foot from the accelerator pedal.
The vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
If you do not fully release the accelerator
pedal, the DISTRONIC
PLUSSuspendedmes-
sage appears in the multifunction display. The
set distance to a slower-moving vehicle in
front will then not be maintained. You will be
driving at the speed you determine by the
position of the accelerator pedal.
You can also activate DISTRONIC PLUS when
stationary. The lowest speed that can be set is
20 mph (30 km/h).
XBriefly pull the cruise control lever towards
you ?, up :or down ;.
DISTRONIC PLUS is activated.
