157The Front Assistant (from here on only referred to as the system) warns you of
the danger of a collision with a vehicle or another obstacle in front of the vehi-
cle, and tries to avoid a collision or mitigate its consequences by automatically
applying the brakes where necessary.
The area in front of the vehicle is monitored by a radar sensor » Fig. 154 on
page 155 .WARNING■
The system only serves to support and does not relieve the driver of the
responsibility for the vehicle operation.■
The system 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 inter-
vene!
■
Always adapt your speed and safety proximity to the vehicle ahead to the
current visibility, weather, road and traffic conditions.
■
The increased passenger protection afforded through the system must
not tempt you to take greater risks than otherwise – risk of accident!
■
The system does not respond to crossing or oncoming objects.
CAUTION
In case of failure of more than one brake light on the vehicle or on the electri-
cally connected trailer, the system becomes unavailable.

155Assist systems

The pre-warning display can occur in the following situations.› If there is a risk of collision with a moving obstacle at a driving speed range
of approx. 30 km/h to approx. 210 km/h.
› If there is a risk of collision with a stationary obstacle at a driving speed
range of approx. 30 km/h to approx. 85 km/h.
When the advance warning is issued, the brake pedal must be pressed or the
moving obstacle avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake Support
If the driver does not brake sufficiently in the event of an impending collision,
the system automatically increases the braking force.
The brake support only occurs as long as the brake pedal is being firmly press-
ed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by means of a steering intervention.
Activating/deactivating
Read and observe
and on page 155 first.

The START-STOP system (hereinafter referred to as the system) saves fuel and
reduces polluting emissions and CO 2 emissions by turning the engine off, e.g.
when stopping at traffic lights, and starting the engine again when moving off.
WARNING■ Never let the vehicle roll with the engine switched off.■The brake servo unit and power steering only operate if the engine is run-
ning.
Operating conditions of the system
Fig. 156
Engine is automatically switched
off / automatic engine cut off is
not possible
Read and observe on page 158 first.
For system-dependent automatic engine shutdown
to work, the following conditions must be met.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
Some additional conditions for the system to function correctly cannot be in-
fluenced or recognised by the driver. Therefore, the system can react differ-
ently in situations which are identical from the driver's perspective.
If, after stopping the vehicle, the check icon 
» Fig. 156 appears on the dis-
play, then the conditions for automatic engine shutdown are not met.
Running the engine is essential for the following reasons, for example.
› The engine temperature for the proper function of the system has not yet
been reached.
› The charge state of the vehicle battery is too low.
› The current consumption is too high.
› High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
Information about the current status of the system can be displayed in the In-
fotainment display » operating instructions for Infotainment , chapter Vehicle
settings (CAR button) .
Note
■
If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
After the manual engine start and with a manual gearbox the automatic en-
gine shutdown can take place only when a minimum distance required for the
system function has been covered.

Further information on automatic transmission
Engine shut down takes place when the selector lever is in positions P, D/S , N
and in Tiptronic mode.
When the selector lever is in position P the engine remains shut down after
you release the brake pedal. The engine starts automatically by pressing the
gas pedal or by moving the selector lever into a different mode and releasing
the brake pedal.
If the engine is off due to the automatic and the selector lever is put to the R
position then the automatic starts the engine.
If the gear selector is moved from position R to the position D/S or N the vehi-
cle must reach a speed of more than 10 km / h before the automatic engine
shutdown starts.
There is no automatic engine shutdown when the system detects a vehicle
moving due to a large steering angle.
No automatic engine shutdown takes place when the vehicle is moving at low
speed (e.g. during a traffic jam or when tuning) and remains stationary after
pressing the brake pedal lightly. Automatic engine shutdown takes place if you
press the brake pedal down with more force.
System related automatic start-up
Read and observe
on page 158 first.
When the engine is off, the system can automatically start the engine beforethe desired journey continues. Some possible reasons for this are:
› The vehicle begins to roll, e.g. on a slope.
› The brake pedal has been actuated several times.
› The current consumption is too high.

NoteThe system component service life is monitored electronically. Further infor-
mation » page 38 ,  Security systems .
Function
Read and observe
on page 161 first.
The system is activated whenever the ignition is switched on, and is ready tointervene automatically under the following conditions.
The engine is running.
The vehicle moves at a speed of more than 30 km/h.
In critical driving situations (e.g. during emergency braking or a sudden change
in direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
› The front passenger's and driver's seatbelts, if worn, are automatically
ten-
sioned closely over the body.
› The windows in the side doors (if open) are automatically closed up to a gap
of about 5 cm from the edge.
› The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.
The first level of protection can be deactivated by one of the following meas-
ures.
› Deactivation of the system in Infotainment
» Operating instructions for Info-
tainment , chapter Vehicle settings (CAR button) .
› Deactivation of TCS
» page 139.
› Selecting the driving mode Sport
» page 160.
Provided that the driving mode Sports is not selected, the system is activated over the two levels of protection after switching the ignition off and on again.
The second level of protection
The system intervenes only if the situation is evaluated as critical, such as in
panic braking at high speeds.

Exterior mirrors
You have to have additional exterior mirrors fitted if you are not able to see
the traffic behind the trailer with the standard rear-view mirrors. The national
legal requirements must be observed.
Headlights
The front of the vehicle may lift up when a trailer is being towed and the head-
lights may dazzle other road users.
Adjust the headlights using the headlight beam control » page 71, Operating
the lights 1)
.
Power to the trailer power grid
For the electrical connection between the vehicle and trailer, the trailer's pow-
er supply is provided by the vehicle.
The power supply works with ignition on or off.
WARNING■ Incorrectly or improperly connected electrical installations may cause the
entire vehicle electronics to malfunction, and may lead to accidents and se-
rious injury from electric shock.■
Work on the electrical system must only be carried out by specialist ga-
rages.
■
Never directly connect the trailer's electrical system with the electrical
connections for the tail lights or other current sources.
■
After attaching the trailer and connecting the power socket, check that
the rear lights on the trailer are working correctly.
■
The handbrake on the vehicle must be applied when attaching and dis-
connecting the trailer.
■
Never use the safety eye to tow a vehicle!
Loading a trailer
The vehicle/trailer combination must be balanced. whereby the maximum per-
missible drawbar load must be utilised. If the drawbar load is too low, it jeop-
ardises the performance of the vehicle/trailer combination.
Distribution of the load
Distribute the load in the trailer in such a way that heavy items are located as
close to the trailer axle as possible. Secure the items from slipping.
The distribution of the weight is very poor if your vehicle is unladen and the
trailer is laden. Drive at a particularly low speed if you cannot avoid driving
with this combination.
Tyre pressure
Correct the tyre inflation pressure on the vehicle for a “full load” » page 204.
Towing capacity and trailer weight
The permissible trailer load must not be exceeded under any circumstan-
ces » page 238 , Technical data .
The details given in the vehicle's technical documentation always take prece-
dence over the details in the Owner's Manual.
The trailer loads specified apply only to altitudes up to 1 000 metres above
mean sea level.
The engine output falls as the height increases, as does the ability to climb.
Therefore, for every additional 1000 m in height (or part), the maximum per-
missible towed weight must be reduced by 10%.
The towed weight is made up of the actual weights of the loaded towing vehi-
cle and the loaded trailer.
The trailer and drawbar load information on the type plate of the towing de-
vice are merely test data for the towing device. The vehicle-specific values are
detailed in the vehicle documents.WARNING■ The maximum permissible axle and drawbar load and the permissible
weight of the trailer must not be exceeded - risk of accident!■
Sliding cargo can significantly adversely affect stability and driving safety
- risk of accident!

Applies to vehicles with bi-xenon headlights.
175Hitch and trailer

Trailer operation
Driving speed
For safety reasons, do not drive faster than 80 km/h when hitching a trailer.
Immediately reduce your speed as soon as even the slightest swaying of the
trailer is detected. Never attempt to stop the trailer from “swaying” by acceler-
ating.
Brakes
Apply the brakes in good time! If the trailer is fitted with a trailer brake, apply
the brakes gently at first, then brake firmly. This will avoid brake jolts resulting
from the trailer wheels locking.
On downhill sections shift down a gear in good time to also use the engine as
a brake.
Engine overheating
If the needle for the coolant temperature gauge moves into the right-hand
area or the red area of the scale, the speed must be reduced immediately.
Stop and switch off the engine if the warning symbol  in the instrument clus-
ter » page 41 lights up.
The following information must be observed » page 41,
 Coolant
.
The coolant temperature can be reduced by switching on the heating.WARNING■ Always drive particularly carefully with the trailer.■Adapt your speed to the conditions of the road surface and to the traffic
situation.
CAUTION
If you tow a trailer frequently, you should also have your vehicle inspected be-
tween service intervals.
Anti-theft alarm system
If the vehicle is locked, the alarm is activated when the electrical connection to
the trailer is interrupted.
Always switch off the anti-theft alarm system before a trailer is coupled or un-
coupled » page 59 .
Conditions for including a trailer in the anti-theft alarm system.
The vehicle is factory-fitted with an anti-theft alarm system and a towing
device.
The trailer is electrically connected to the towing vehicle by means of the
trailer socket.
The electrical system of the vehicle and trailer is functional.
the vehicle is locked with the vehicle key and the anti-theft alarm system
is activated.
CAUTION
For technical reasons, trailers with rear LED lights cannot be connected to the
anti-theft alarm system.176Driving

WheelsRead and observe
and on page 182 first.
Wheel rims
Also thoroughly wash the wheel rims when washing the vehicle on a regular
basis.
Regularly remove salt and brake abrasion, otherwise the rim material will be
corroded.
Light alloy wheels
After washing thoroughly and treat the wheel rims with a protective product
for light alloy wheels.
For the treatment of wheel rims do not use products which may cause damage
to the paint on the rims.
CAUTION
■ Damage to the paint layer on the wheel rims must be touched up immediate-
ly.■
Severe layers of dirt on the wheels can also result in wheel imbalance. This
may show itself in the form of a wheel vibration which is transmitted to the
steering wheel which, in certain circumstances, can cause premature wear of
the steering. This means it is necessary to remove the dirt.
Towing hitch and mounting recess
Read and observe
and on page 182 first.
Seal the mounting recess with the cap to prevent any ingress of dirt.
In the event of dirt, clean the interior surfaces of the mounting recess and
treat with a suitable preservative.
Always check the ball head before attaching a trailer. Apply suitable grease
where necessary.
Include the protective cap when stowing away the ball rod to protect the boot
from getting contaminated.
CAUTION
Apply grease to the inner part of the mounting recess. Make sure you do not
remove any grease.Under-body protection
Read and observe
and on page 182 first.
The underside of your vehicle is already permanently protected by the factory
against chemical and mechanical influences.
It is not possible to guarantee that the protective coating will not suffer any
damage as the vehicle is driven.
We recommend having the protective coating underneath the vehicle and the
chassis checked — preferably before the beginning of winter and at the end of
winter.
WARNINGNever use additional underbody protection or anti-corrosion agents for ex-
haust pipes, catalytic converters, diesel particle filters or heat shields.
When the engine reaches its operating temperature, these substances
might ignite - risk of fire!
Wiper blades
Read and observe
and on page 182 first.
Clean the wiper blades regularly with a glass cleaner. The wiper blades should
be cleaned with a sponge or cloth if they are heavily soiled by insect residues,
for example.
The wiper blades can become soiled with wax residues after washing in auto-
matic vehicle wash systems for example » page 181.
