particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended in
the vehicle.

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
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lock Braking System)
RASR (Acceleration SkidControl)
RBAS (B rakeAssist System)
REBD (E lectronic Brake Force Distribution)
RESP®(Electronic StabilityProgram)
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 accident nor override the
laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for the distance to the vehicle in
front, for vehicle speed, braking in good time
and for staying in your lane. Always adapt your
driving style to the prevailing road and weather
conditions and maintain a sufficient, safe dis-
tance from other road users. Drive carefully.
Please note that the driving safety systems
described only work optimally when:
Rthere is adequate contact between the tires
and the road surface
Ryou use winter tires (M+S tires), with snow
chains if necessary, when the road conditions
are wintry.
52Driving safety systems
Safety
XKeep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes function as usual again if:
Ryou release the brake pedal
Rthere is no longer any danger of a collision
Rno obstacle is detected in front of your vehicle
Adaptive Brake Assist is then deactivated.
Up to the maximum vehicle speed, adaptive
Brake Assist can react to moving obstacles that
have already been recognized as such at least
once over the period of observation. Adaptive
Brake Assist does not react to stationary obsta-
cles.
In particular, the detection of obstacles can be
impaired if:
Rdirt on the sensors or anything else covering
the sensors
Rsnow or heavy rain
Rinterference from other radar sources
Rthere are strong radar reflections, for exam-
ple in parking garages
Ra narrow vehicle traveling in front, e.g. a
motorbike
Ra vehicle traveling in front on a different line
If adaptive Brake Assist is not available due to a
malfunction in the radar sensor system, the full
brake boosting effect with the help of BAS
remains available.
Following damage to the front end of the vehicle,
have the configuration and operation of the
radar sensor checked at a qualified specialist
workshop. This also applies to collisions at slow
speeds where there is no visible damage to the
front of the vehicle.
Lane Tracking package
Blind Spot Assist
General notes
Blind Spot Assist uses a radar sensor system to
monitor the areas on both sides of your vehicle.
It supports you from speeds of approximately
20 mph (30 km/h). A warning display in the
exterior mirrors draws your attention to vehicles detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audible collision warning. For this purpose, Blind Spot Assist uses sensors in the rear bumper and
behind the protective strips of the B-pillars.
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with a large speed
differential and overtake your vehicle
As a result, Blind Spot Assist may not give
warnings in such situations. There is a risk of
an accident.
Always observe the traffic conditions care-
fully, and maintain a safe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving.
iUSA only:
This device has been approved by the FCC as
a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar
system only. Removal, tampering, or altering
of the device will void any warranties, and is
not permitted by the FCC. Do not tamper with,
alter, or use in any non-approved way.
Any unauthorized modification to this device
could void the user’s authority to operate the
equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can be
impaired in the case of:
Rdirt on the sensors or anything else covering
the sensors
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rnarrow and short vehicles, e.g. motorcycles
or bicycles
Rvery wide lanes
Rnarrow lanes
Rvehicles not driving in the middle of their lane
Rbarriers or other road boundaries
Vehicles in the monitoring range are then not
indicated.
144Driving systems
Driving and parking
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0m) behind your vehicle and
approximately 1.6 ft (0.5 m)to 11.5 ft (3.5 m)
ea ch side of it. For this purpose, Blind Spot
Assist uses radar sensors in the rear bumper
and behind the protective strips of the B-pillars.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Ra clear warning situation may not occur. The
yellow indicator lamp on the relevant side of
the vehicle will then light up.
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rwarnings may be interrupted when driving
alongside particularly long vehicles, for exam-
ple trucks, for a prolonged time.
The four sensors of Blind Spot Assist are inte-
grated into the rear bumper and behind the pro-
tective strips of the B-pillars. Make sure that the
bumper and protective stripping are free of dirt,
ice or slush in the vicinity of the sensors. The
radar sensors must not be covered, for example
by cycle racks or overhanging loads. Have the function of the radar sensors checked
at a qualified specialist workshop:
Rafter a severe impact
Rafter damage to the bumper
Rafter damage to the protective strips of the B-
pillars
Blind Spot Assist may otherwise not work prop-
erly.
Indicator and warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
:Yellow indicator lamp/red warning lamp
If yellow indicator lamp :lights up:
Ryou are driving at less than 20 mph (30 km/h)
RBlind Spot Assist is deactivated
RBlind Spot Assist is malfunctioning
Rthere is no clear warning, depending on the
situation
Blind Spot Assist is active from a speed of
20 mph (30 km/h). If a vehicle is detected in the
blind spot monitoring range, red warning
lamp :on the corresponding side lights up.
This warning occurs when a vehicle enters the
blind spot monitoring range from behind or from
the side. When you overtake a vehicle, the warn-
ing only occurs if the difference in speed is less
than 14 mph (22 km/h).
Yellow indicator lamp :goes out if reverse gear
is engaged. Blind Spot Assist is then deactiva-
ted.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi- ent light.

up red for approximately 1.5 seconds and
then turn yellow.
XTo deactivate: press thekbutton in the
center console (Ypage 35).
The yellow indicator lamp in exterior mirror :
first flashes and then lights up continuously.
XTo activate: press thekbutton in the
center console again (Ypage 35).
The yellow indicator lamp in exterior mirror :
flashes initially. If you exceed 20 mph
(30 km/h) while driving, the yellow indicator
lamp in exterior mirror :goes out.
Towing a trailer
If you attach a trailer, make sure that you have
correctly established the electrical connection.
This can be accomplished by checking the trailer
lighting. Blind Spot Assist is deactivated as a
result. The indicator lamp in the exterior mirrors
lights up yellow.
On veh icles wit
h steering wheel buttons, the
Blind Spot Assist Deactivatedmessage
also appears in the display.
Lane Keeping Assist
General notes
Lane Keeping Assist monitors the area in front of
your vehicle by means of a camera at the top of
the windshield. Lane Keeping Assist detects
lane markings on the road and warns you before
you leave your lane unintentionally.
:Lane Keeping Assist camera
Lane Keeping Assist supports you from speeds
of approximately 40 mph(60 km/h).
If Lane Keeping Assist detects lane markings,
the à indicator lamp in the instrument clus-
ter lights up green. Lane Keeping Assist is opera-
tional.
Important safety notes
GWARNING
Lane Keeping Assist may not always clearly
recognize lane markings.
In this case, Lane Keeping Assist may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Always pay particular attention to the traffic
situation and stay in lane, in particular if
warned by Lane Keeping Assist.
GWARNING
The Lane Keeping Assist warning does not
return the vehicle to the original lane. There is
a risk of an accident.
You should always steer, brake or accelerate
yourself, in particular if warned by Lane Keep-
ing Assist.
If you fail to adapt your driving style, Lane Keep-
ing Assist can neither reduce the risk of accident
nor override the laws of physics. Lane Keeping
Assist cannot take into account road, weather or traffic conditions. Lane Keeping Assist is only an
aid. You are responsible for the distance to the
vehicle in front, for vehicle speed, braking in
good time and for staying in your lane.
