The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.
The error display is in Chapter » page 28, Warning lights .WARNINGThe general information relating to the use of assistance systems must be
observed » page 100, in section Introduction .
Stability Control (ESC)
Read and observe
on page 101 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehiclestarts to skid) by braking individual wheels to maintain the desired direction.
If there is a TCS intervention, the indicator light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 101 first.
ABS prevents the wheels locking when braking. Thereby, it helps the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not pump the brakes or lift off the brake
pedal.
Engine drag torque control (MSR)
Read and observe
on page 101 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
101Assist systems
Multi collision brake (MCB)Read and observe
on page 101 first.
MCB helps to decrease speed after a collision by means of automatic braking
interventions and to stabilise the vehicle. This reduces the risk of a subse-
quent crash due to uncontrolled vehicle movement.
The automatic brake interventions can take place only if the following condi-
tions are met.
There was a front, side and rear-end collision of a certain severity.
The impact speed was greater than approx. 10 km/h.
The brakes, the ESL and other required electrical systems remain function-
al after impact.
The accelerator pedal is not actuated.

The parking aid (hereinafter referred to as "system") draws attention to obsta-
cles in the vicinity of the vehicle via acoustic signals or on the Infotainment
display when manoeuvring.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
Moving persons or objects may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of
clothing cannot reflect the system signals. There is a danger that such ob-
jects or people may not be recognised by the system sensors.
WARNING (Continued)■ External noise sources may affect the signals of the system sensors.
There is a danger that obstacles may not be recognised by the system sen-
sors.■
Before reversing, you should satisfy yourself that there are no small ob-
stacle, such as a rock, thin post etc., in front or behind your vehicle. Such
obstacles may not be recognised by the system sensors.
CAUTION
■ Keep the system sensors » Fig. 127 on page 103 clean, snow-and ice-free
and do not cover with any objects of any kind, otherwise the system function-
ing may be impaired.■
In adverse weather conditions (heavy rain, water vapour, very low or high
temperatures, etc.), the functioning of the system may be impaired - “incorrect
recognition of obstacles”.
■
Accessories additionally installed on the vehicle rear, such as bicycle carriers,
can impair the system function.

The Adaptive Cruise Control (hereinafter referred to as ACC) maintains the set
speed or the distance to the vehicle ahead without the accelerator or brake
pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 100.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 100, in section Introduction .■
The driver must always be ready to take over the operation of the accel-
erator and brake pedal.
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
Driving into “sharp” corners or in steep gradients / on steep inclines.
■
When driving through places where metal objects (such as metal build-
ings, railway tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

on page 110 first.
The ACC allows a speed of 30-160 km/h to be set or a distance to the preced-
ing vehicle to be very short of very long to be set.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar
sensor.

Note to reduce speed
If the delay of the ACC is insufficient in relation to the vehicle in front, the
warning light lights up in the instrument cluster and the display shows a
message to engage the brake pedal.
1234NoteSome ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.
Automatic stop-start
Read and observe
on page 110 first.
Vehicles with an automatic transmission can decelerate to a complete stop
and start moving again using the ACC.
Decelerate to a complete stop
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a complete stop.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be controlled. Control is
automatically disconnected in case of longer holding periods.

Overtaking and towingRead and observe
on page 110 first.
When overtaking
When your vehicle is being controlled at a speed that is lower than the set
speed and the turn signal is operated, ACC assesses this situation as meaning
that the driver wishes to overtake. The ACC automatically accelerates the vehi-
cle, thereby reducing the proximity to a vehicle ahead.
If your vehicle changes to the overtaking lane and no vehicle is detected
ahead, ACC accelerates until the set speed is reached and then keeps it con-
stant.
Acceleration can be cancelled at any time by touch on the brake pedal or
pressing the button on the lever
» Fig. 142 on page 111 .
Towing a trailer
When towing, or if another accessory is connected to the trailer socket, ACC control is set with a lower rate. The manner of driving should therefore be
adapted to this limitation.
Malfunctions
Read and observe
on page 110 first.
If, for some unknown reason, ACC is not available, the warning light appears
in the display of the instrument cluster and an appropriate message is shown.
Sensor covered / dirty
If the sensor is dirty or covered, a message indicating that there is no sensor
view appears. Clean the sensor cover or remove the obstacles » Fig. 125 on
page 100 .
ACC not available
If the ACC is currently unavailable, a message concerning the unavailability ap-
pears. Stop the vehicle, switch off the engine and then start it again. If ACC
continues to be unavailable, seek the assistance of a specialist garage.
ACC fault
With an ACC fault, an error message appears. Seek help from a specialist ga-
rage.

TCS is activated » page 102.
The vehicle is travelling forwards at a speed of more than approx. 5 km/h.
114Driving
Automatic Car Washes
The usual precautionary measures must be taken before washing the vehicle
(e.g. closing the windows and the tilt/slide roof etc.).
If your vehicle is fitted with any particular attached parts (e.g. spoiler, roof rack system, two-way radio aerial etc.), it is best to consult the operator of the car
wash system beforehand.
After an automatic wash with wax treatment, the wiper blades should be
cleaned with cleaning agents specially designed for the purpose, and then de-
greased.
Pressure Washers
When washing the vehicle with a high-pressure cleaner, the instructions for
use of the equipment must be observed. This particularly applies to instruc-
tions regarding the pressure and spraying distance from the vehicle surface.WARNING■
Washing your vehicle in the winter: Water and ice in the brake system can
affect the braking efficiency – there is the risk of an accident.■
Take care when cleaning the underbody or the inside of the wheel wells -
there is a risk of injury from sharp metal parts!
CAUTION
■ Do not wash the vehicle in direct sunlight, do not exert pressure on the body
while washing. The temperature of the washing water should be no more than
60 °C max. - otherwise there is a risk of damaging the vehicle paint.■
Before driving through a car wash fold in the exterior mirrors - There is a risk
of damage.
■
For vehicles with a roof antenna, the antenna rod should be unscrewed be-
fore driving through a car wash - there is a risk of damage.
CAUTION
Washing the vehicle with high-pressure cleaners■Films should not be washed with any high-pressure cleaners - risk of dam-
age.■
Do not aim the water jet directly at the lock cylinders or the door or opening
joints when washing the vehicle in the winter – there is a risk of freezing.
■
Hold a large spraying distance to the rear camera lens, to plastic parts (e.g.
Roof racks, spoilers, protective strips and the like), as well as soft materials
such as rubber hoses or insulation material.
■
The sensors of the parking aid can be sprayed only for a short time and there
must be a minimum distance of 10 cm - there is a risk of damage.
