The gearbox does not shift up into the highest gear until the engine has reached
its maximum revolutions for this gear range.WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control of
the vehicle – risk of accident!

New engine
First read and observe the introductory information given on page 130.
The engine has to be run in during the first 1500 kilometres.Up to 1000 kilometres
›
Do not drive faster than 3/4 of the maximum speed of the gear in use, i.e. 3/4 of
the maximum permissible engine speed.
›
No full throttle.
›
Avoid high engine speeds.
›
Do not tow a trailer.
From 1000 up to 1500 kilometres
Gradually increase the power output of the engine up to the full speed of the
gear engaged, i.e. up to the maximum permissible engine speed.
The red scale of the rev counter indicates the range in which the system beginsto limit the engine speed.
During the first operating hours the engine has higher internal friction than later until all of the moving parts have harmonized. The driving style which you adopt
during the first approx.1500 kilometres plays a decisive part in the success of run-
ning in your car.
Never drive at unnecessarily high engine speeds, even after the running-in period is complete.
On vehicles fitted with a manual gearbox, at the very latest shift up into the next
gear when the red area is reached. Observe the recommended gear » page 27.
Very high engine speeds when accelerating (accelerator) are automatically re-
stricted »
.
With vehicles with a manual gearbox, do not drive at unnecessarily low engine
speeds. Shift down a gear when the engine is no longer running smoothly. Ob-
serve the recommended gear » page 27.
CAUTION
■
The engine is not protected from excessive engine revs caused by shifting
down at the wrong time. This can result in the sudden increase in revs beyond
the permissible maximum rpm and thus cause engine damage.■
Never rev up a cold engine when the vehicle is stationary or when driving in in-
dividual gears.
For the sake of the environment
Do not drive at unnecessarily high engine speeds. Shifting up sooner helps save
on fuel, reduces engine noises and protects the environment.
New tyres
First read and observe the introductory information given on page 130.
New tyres have to be “run in” since they do not offer optimal grip at first. Drive
especially carefully for the first 500 km or so.

140WARNING■ A lack of fuel can cause irregular engine running or cause the engine to shut
down. The brake assist systems would then fail to function – risk of accident!■
Adjust the speed and driving style to the current visibility, weather, road and
traffic conditions. The increased safety offered by the brake assist systems must not tempt you to take greater risks than otherwise – risk of accident!
■
In the event of an ABS fault, visit a specialist garage immediately. Adjust
your style of driving according to the damage to the ABS as you will not know
how great the damage is and the limitation it is placing on the braking effi-
ciency.
CAUTION
■ All four wheels must be fitted with the same tyres approved by the manufactur-
er to ensure the brake assist systems operate correctly.■
Changes to the vehicle (e.g. to the engine, brakes, chassis) can influence the
functionality of the brake assist systems » page 200.
■
If a fault occurs in the ABS system, the ESC, ASR and EDL also do not work. An
ABS fault is indicated with the warning light » page 18 .
Electronic Stability Control (ESC)Fig. 127
ESC button
First read and observe the introductory information and safety warn-
ings on page 137.
The ESC system helps to maintain control of the vehicle in situations where it is
being operated at its dynamic limits, such as a sudden change to the direction of
travel. The risk of skidding is reduced and your car thus offers greater driving sta-
bility depending on the conditions of the road surface.
The ESC system is automatically activated each time the ignition is switched on.The direction which the driver wishes to take is determined based on the steering angle and the speed of the vehicle and is constantly compared with the actualbehaviour of the vehicle. If differences exist, such as the car beginning to skid,
the ESC system will automatically brake the appropriate wheel.
During an intervention of the system, the warning light
flashes in the instru-
ment cluster.
The following systems are integrated into the Electronic Stability Control (ESC).

137Assist systems
Multicollision brakeFirst read and observe the introductory information and safety warn-
ings
on page 137.
The multifunction brake deploys automatic braking after a collision in order to re- duce the risk of further collisions. Automatic braking can only be deployed at
speeds of over 10 km/h in the event of a frontal or side impact.
The vehicle is slowed down automatically by the ESC system as long as the brakes, the ESC and the relevant electrical system remain operational after the impact.
Automatic braking is not applied if the driver presses the accelerator during the
accident.

142WARNING■ The parking aid is not a substitute for the driver paying proper attention and
it is always the driver's responsibility to take care when reversing the vehicle
or carrying out similar manoeuvres. Pay particular attention to small children
and animals as they may not be recognised by the system sensors.■
You should satisfy yourself before reversing that there is no small obstacle,
such as a rock, thin post, trailer drawbar etc., in front or behind your vehicle.
Such obstacles may not be recognised by the system sensors.
■
Under certain circumstances, surfaces of certain objects and types of cloth-
ing cannot reflect the system signals. Thus, these objects or people who wear such clothing are not recognised by the System sensors.
■
External sound sources can have a detrimental effect on the system. Under
adverse conditions, this can cause objects or people to not be recognized by
the system.
CAUTION■ If a warning signal sounds for about 3 seconds after activating the system and
there is no obstacle close to your car, this indicates a system fault. The fault is
also indicated by the symbol flashing » Fig. 129 on page 141 in the button. ! or
appears in the Infotainment display. Seek help from a specialist garage.■
The sensors must be kept clean (free of ice, etc.) to enable the system to oper-
ate properly.
■
The system function may be limited under adverse weather conditions (heavy
rain, water vapour, very low or high temperatures etc.).
■
Additional mounted modules, such as a bicycle carrier, can impair the function of
the parking aid.
Note
■ The signal tones for front obstacle recognition are factory-set to be higher than
for rear obstacle recognition.■
If not all fields around the vehicle are shown after the system is activated, the
vehicle will need to be moved a few metres forwards or in reverse.
■
If the system is activated and the selector lever of the automatic gearbox is in
position P (the vehicle cannot move), the warning tone is interrupted and no ob-
stacles are displayed.

The parking aid (hereafter only referred to as system) works only when the igni- tion is switched on.
The system supports the driver using acoustic signals/Infotainment display when
parking and manoeuvring.
The system uses ultrasound waves to calculate the distance between the bumper
and an obstacle. The ultrasound sensors are integrated in the front/rear bumper.
Image Description - approximate range of sensors (in cm)Range » Fig. 12912 sensors8 sensors4 sensorsA120120-B9060-C160160160D906060E90--
The interval between the acoustic signals becomes shorter as the clearance is re-
duced. A continuous tone sounds from a distance of approx. 30 cm - danger area.
From this moment on do not continue driving!
The length of the vehicle can be increased with an installed detachable towing
device. The danger area thus begins at a distance of around 35 cm on vehicles
equipped with a factory-fitted towing device.
For information on setting the acoustic signals and a description of the Infotain-
ment display see » Infotainment manual , chapter Vehicle settings (button CAR) .
Activation/deactivation
The system is automatically activated by selecting reverse gear or pressing the
symbol button
» Fig. 129 . The symbol
lights up in the button; activation is
confirmed by a brief acoustic signal.
The system is deactivated by moving out of reverse gear, either by pressing the
symbol button
or automatically at a speed exceeding 10 km/h (the symbol
in
the button goes out).
On vehicles which only have rear sensors, the system can only be deactivated by
moving out of reverse gear.
Towing a trailer

The Cruise Control System (CCS) maintains a set speed, more than 25 km/h, with-
out you having to actuate the accelerator pedal.
This is only possible within the range which is permitted by the power output and
braking power of the engine.
The warning light
illuminates in the instrument cluster when the cruise control
system is switched on.
WARNING■ For safety reasons, the cruise control system must not be used in dense
traffic or on unfavourable road surfaces (such as icy roads, slippery roads,
loose gravel) – risk of accident!■
The saved speed may only be resumed if it is not too high for the current
traffic conditions.
■
Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.
CAUTION
■ The cruise control system is not able to maintain a constant speed when driving
in areas with very steep gradients. The weight of the vehicle increases the speed
at which it travels. In such cases, a lower gear should be engaged or the foot-
brake applied.■
It is not possible to switch on the cruise control system if the first gear or re-
verse gear is engaged (Vehicles fitted with a manual transmission)
■
The cruise control system cannot be activated when the selector lever is in po-
sitions P, N or R (vehicles with automatic transmission).
146Driving
WARNING (Continued)■If the ACC does not decelerate fast enough, immediately apply the vehicle's
footbrake.■
Control may only be resumed if the stored speed is not too high for the cur-
rent traffic conditions.
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).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
CAUTION
■ It is not possible to switch on the control on vehicles fitted with a manual
transmission if the first gear or reverse gear is engaged.■
It is not possible to switch on the control on vehicles fitted with an automatic
transmission , if the selector lever is in the position P, N or R .
■
The control may automatically switch off when some brake assist systems (e.g.
ESC) intervene, when the maximum permissible engine speed is exceeded, etc.
Note
■ The speed can only be set and stored when ACC is activated. The stored speed
may differ from the actual speed if a proximity control procedure is in progress at the time.■
Vehicles with an automatic transmission can decelerate to a standstill and start
again using the ACC.
■
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 auto-
matic 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 electri-
cally connected trailer, the ACC becomes unavailable.
Radar sensorFig. 135
Mounting location of the radar
sensor
First read and observe the introductory information and safety warn-
ings on page 148.
The radar sensor » Fig. 135 (From here on referred to as sensor) is used to assess
the traffic situation in front of the vehicle.
The sensor can distinguish objects by radiating and receiving electromagneticwaves.
The sensor function may be impaired in the events of one of the following.
› The sensor is covered by mud, snow or debris, for example.
› The sensor or its immediate surroundings are covered by other objects, for ex-
ample, a sticker is attached.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
If the sensor is dirty or does not have “visibility” for any other reason, the follow- ing message appears in the instrument cluster display.
ACC: no sensor view!
Stop the car, switch off the engine and clean the sensor or eliminate the obstacle
causing the lack of“visibility”. Should the ACC still be unavailable after the engine is restarted,
» Fig. 138 on page 151 push the lever into position. Seek help
from a specialist garage.
149Assist systems
Narrow vehicles or vehicles travelling side by side
Narrow vehicles or vehicles travelling side by side are not detected by the radar
sensor until they are within the sensor's range » Fig. 139 - . This is especially
true for narrow vehicles, such as motorcycles.
If necessary, slow down the car by applying the brake.
Other vehicles changing lanes
Vehicles that change onto the lane with a small proximity » Fig. 140 - do not
have to be detected by the radar sensor in time. The result may be a delayed ACC
response.
If necessary, slow down the car by applying the brake.
Stationary vehicles
The ACC does not detect stationary objects! When a vehicle detected by the ACC turns or sheers off and there is a stationary vehicle in front of this vehi-cle, » Fig. 140 -
the ACC does not respond to the stationary vehicle.
In such cases, take over the steering and apply the brake.
When overtaking
When your vehicle is being controlled (the speed is lower than that which is stor-
ed) and the indicator is activated, the ACC interprets that the driver intends to
overtake. The ACC automatically accelerates the vehicle, thereby reducing the
proximity to a vehicle ahead.
If the vehicle changes to the fast lane and no vehicle is detected ahead, the ACC
accelerates until the set speed is reached and then keeps it constant.
Acceleration can be cancelled at any time by touch on the brake pedal or pressing
the button
on the control lever » Fig. 138 on page 151 .
Vehicles with special load or special body parts
Other vehicles with a load or with body parts protruding from the sides, back or
top of the vehicle contour may not be detected by the ACC.
Control should therefore be disabled whenever you are driving behind or overtak-ing such a vehicle.
Towing a trailer
When towing a trailer, the ACC control will be less powerful. The manner of driv- ing should therefore be adapted to this limitation.
Information messages
First read and observe the introductory information and safety warn-
ings
on page 148.
If the symbol
appears in the instrument cluster display when ACC is enabled, it
means that the ACC is not working.
The messages and information are indicated in the instrument cluster display. ACC: no sensor view!
The sensor is dirty or has no “visibility”. Stop the car, switch off the engine and
clean the sensor or remove the obstacle causing the lack of “visibility” » Fig. 135

push the lever into position
» Fig. 138 on page 151 . Seek help from a specialist
garage.

The area monitoring system (From here on only referred to as Front Assist) warns
you of the danger of a collision with an obstacle in front of the vehicle and tries to
avoid a collision or mitigate its consequences by automatically applying the
brakes as appropriate.WARNING■ Front Assist only works as an aid, it does absolve the driver of the responsi-
bility to maintain full control over the vehicle's steering.■
Front Assist has physical and system related limitations. For this reason, the
driver may experience some undesired or delayed system responses in certain
situations. You should therefore always be alert and ready to intervene!
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
■
If Front Assist gives a warning, then, depending on the traffic situation, im-
mediately slow down the car by applying the brakes or avoid the obstacle.
■
The increased safety through the Front Assist system must not tempt you
to take greater risks than otherwise – risk of accident!
■
The driver must always be ready to take over steering of the vehicle himself
(brake or accelerate).
■
Front Assist does not respond to crossing or oncoming objects.
Instructions and Information
First read and observe the introductory information and safety warn-ings
on page 154.
Front Assist may become impaired in the following situations, for example.
› When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
› Driving around “sharp” bends.
› When fully pressing down the accelerator pedal.
› If there is a fault with the Front Assist system.
› When one of the brake assist systems (e.g. ESC) intervenes.
WARNINGIn the following situations, Front Assist should be switched off for safety rea-
sons.■
When the vehicle is being towed away.WARNING (Continued)■ When the vehicle is on a rolling test bench.■When an undesired activation has repeatedly occurred.■
When on a truck, train or a car ferry service or the like.
CAUTION
Narrow vehicles or vehicles travelling side by side are not detected by Front As-
sist via the radar sensor until they are within the sensor's range. This is especially
true for narrow vehicles, such as motorcycles.
Note
In case of failure of more than one brake light on the vehicle or on the electrically
connected trailer, Front Assist not available.
