uation and beready to brake.
GWAR NING
The distance warning function cannot always
clearly identify objects and co mplex traff ic
situations.
In such cases, the distance warning function
may:
Rgive an unnecessary warning
Rnot give a warning
There is a risk of an accident.
Alwa ys pay careful attention to the traff icsit-
uation and donot rely solely on the distance
warning function.
Operation
The distance warning function can help you to
minimize the risk of a front-end collision with a
vehicle ahead or reduce the effects of such a
collision. Ifthe distance warning function
detects that there isa risk of a collision, you will
be warned visually and acoustically. Without
your intervention, the distance warning function
cannot prevent a collision.
The distance warning function willissue a warn-
ing at speeds of around 20 mph (30 km/h)or
more if:
Ryou approach a vehicle ahead of you very
quickly. You will then hear an intermittent
warning tone and the red ·warning lamp
in the instrument cluster flashes.
XBrake immediately in order to increase the
distance from the vehicle in front.
or
XTake evasive action provided it is safe to do
so.
Driving systems139
Driving and parking

If you want the distance warning function to
assist you, the function must be activated and
operational.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
With the help of the radar sensor system, the
distance warning function can detect obstacles
that are in the path of your vehicle for an exten-
ded period of time.
Up to a speed of around 45 mph (70 km/h), the
distance warning function can also react to sta-
tionary obstacles, such as stopped or parked
vehicles.
If you approach an obstacle and the distance
warning function detects a risk of a collision, the
system will alert you both visually and acousti-
cally.
In particular, the detection of obstacles can be
impaired in the case of:
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
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.

Adaptive Brake Assist
iObserve the "Important safety notes" sec-
tion for driving safety systems (Ypage 53).
GWARNING
Adaptive Brake Assist cannot always clearly
identify objects and complex traffic situa-
tions.
In such cases, Adaptive Brake Assist can:
Rintervene unnecessarily
Rnot intervene
There is a risk of an accident.
Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the
intervention in a non-critical driving situation.
GWARNING
Adaptive Brake Assist does not react:
Rto people or animals
Rto oncoming vehicles
Rto crossing traffic
Rto stationary obstacles
Rwhen cornering
As a result, the Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.

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.
Blind Spot Assist monitors the area approx-
imately 10 ft (3.0 m) behind your vehicle and
approximately 1.6 ft (0.5 m) to 11.5 ft (3.5 m)
each side of it. The monitoring range behind the
vehicle may also be larger depending on the sit-
uation.
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:
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 two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear-moun- ted cycle racks or overhanging loads. Following
a severe impact or in the event of damage to the
bumper, have the function of the radar sensors
checked at a qualified specialist workshop.
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.

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.

DSR (Downhill Speed Regulation)
Important safety notes
Observe the notes on braking in the section on
"Driving and parking". If you fail to adapt your
driving style or you are inattentive, DSR can nei-
ther reduce the risk of accident nor override the laws of physics. DSR cannot take road, weather
and traffic conditions into account. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed and for
braking in good time.
General notes
DSR supports you with the LOW RANGE trans-
mission ratio when you are driving downhill off-
road and on construction sites. DSR maintains a
preset speed for you on downhill gradients by
applying the brakes as required. Maintaining the
speed is dependent on the road surface condi-
tions and the downhill gradient and cannot
therefore be guaranteed in all situations.
You can set the speed to between 2.5 mph
(4 km/h) and 11 mph (18 km/h) using the brake
and accelerator pedals or the cruise control
lever.
RIf the vehicle is stationary, or its speed is less
than 2.5 mph (4 km/h) the speed is set to
2.5 mph (4 km/h).
RIf you drive faster than 11 mph (18 km/h) off-
road, DSR switches to standby mode. DSR
remains activated, but does not brake auto-
matically.
RIf you drive downhill slower than 11 mph
(18 km/h), DSR sets the speed to the previ-
ously set speed.
RDSR switches off automatically if you drive
faster than 28 mph (45 km/h).

the LOW RANGE transmission ratio is engaged,
only use the cruise control lever to operate DSR.
When the LOW RANGE transmission ratio is dis-
engaged, use cruise control.
Activation conditions
In order to activate DSR, both activation condi-
tions must be fulfilled:
RThe LOW RANGE transmission ratio is
engaged. The+indicator lamp in the
instrument cluster lights up.
RThe vehicle is stationary or you are not driving faster than 11 mph (18 km/h).
Activating DSR
You can activate DSR when the vehicle is sta-
tionary or moving.
XBrake or accelerate the vehicle to the
required speed between 2.5 mph (4 km/h)
and 11 mph (18 km/h).
XBriefly push the cruise control lever up :or
down =.
or
XBriefly pull the cruise control lever towards
you ;.
XRelease the brake or accelerator pedal.
The current speed is stored. When the vehicle
is stationary, the speed is stored at 2.5
(4 km/h). DSR maintains the stored speed on
the downhill gradient and brakes automati-
cally.
When DSR is activated and the vehicle pulls
away, accelerates or brakes, the speed set cor-
responds to the speed at which the accelerator
or brake pedal is released. Thi s i
s only the case
if you are not driving faster than 11 mph
(18 km/h).

Towing a trailer
Notes on trailer towing
Important safety notes
GWARNING
Installing an unsuitable ball coupling may
result in overloading of the trailer tow hitch
and the rear axle. This applies especially if the ball coupling in question is longer or angled
differently. This could seriously impair the
driving characteristics and the trailer can
come loose. There is a risk of an accident.
You should only ever install a ball coupling
that has the permissible dimensions and that
is designed to meet your trailer-towing
requirements. Do not modify the ball coupling
or the trailer tow hitch.
GWARNING
If you use a ball coupling that is not approved
for your vehicle, it may cause excessive strain
on the trailer tow hitch. This can cause dam-
age to the vehicle and the trailer may come
loose during the journey. The handling may be
impaired and the rear axle may be overloaded.
This may lead to an accident involving serious
or even fatal injury.
Therefore note the following:
ROnly install a ball coupling that is approved for your vehicle.
RBefore the journey, make sure that the ballcoupling is correctly installed and secured.
To do this, observe the operating instruc-
tions of the ball coupling manufacturer.
RDo not make any modifications to the ball
coupling or the trailer tow hitch.
You must observe the operating instructions
of the trailer tow hitch or ball coupling manu-
facturer.
GWARNING
If the ball coupling is not correctly installed
and secured, it could come loose while driving and endanger other road users. There is a risk
of an accident and injury.
