Water under the vehicle
If the humidity and temperature outside the vehicle are high, condensation can drip off the
evaporator of the cooling system and form a pool underneath the vehicle. This is normal and does
not indicate a leak!
If the outside humidity is high and the outside temperature low, condensation may evaporate when
the auxiliary heater is running ⇒ Auxiliary heater and ventilation . If this is the case, steam may
appear underneath the vehicle. This is not a sign that the vehicle is damaged.

WARNING
Poor visibility through all windows increases the risk of collisions and accidents, which can cause
serious injuries.

Always ensure that all windows are free of ice, snow and mist to ensure good visibility.
Maximum heat output and the fastest possible defrosting of the windows are possible only when
the engine is running. Do not start your journey until you have good visibility.
To help ensure good visibility, make sure that you use the air conditioning system and the rear
window heating correctly.
Auxiliary heater and ventilation
Introduction
This chapter contains information on the followingsubjects:
⇒ Switching the auxiliary heater and ventilation on and off 
⇒ Programming the auxiliary heater and ventilation 
⇒ Remote control 
The auxiliary heater and ventilation system can be used to heat the vehicle interior in the winter and
ventilate it in the summer. It is able to clear ice, condensation and a thin layer of snow from the
windscreen. The auxiliary heater is supplied with fuel from the vehicle fuel tank and can be operated
when the vehicle is stationary with the ignition switched off. The auxiliary ventilation system is
powered by the 12-volt vehicle battery.
Auxiliary heater exhaust system
The emissions generated by the auxiliary heater are discharged via an exhaust pipe underneath the
vehicle. The exhaust pipe must not be blocked by snow, mud or other objects.

WARNING
Among other things, the emissions from the auxiliary heater contain carbon monoxide, which is an
odourless and colourless poisonous gas. Carbon monoxide can cause people to lose consciousness. It
can also cause death.
Never switch on the auxiliary heater when the vehicle is in unventilated or closed rooms nor let the
auxiliary heater run in unventilated or closed rooms.
Never program the auxiliary heater so that it is switched on and runs in unventilated or closed
rooms.

WARNING
Parts of the auxiliary heater exhaust system become very hot. This can cause fires.
Park the vehicle so that no part of the exhaust system can come into contact with any inflammable
material underneath the vehicle, e.g. dry grass.

The alternator is driven by the engine and generates electrical power for convenience consumers
such as the air conditioning system, windscreen heating and ventilation. Saving electrical energy is
easy, e.g.:
Open the windows and doors before driving at high outside temperatures and drive for a short
distance with a window open. Only then switch the air conditioning system on.
Switch the convenience consumers off as soon as they have served their purpose.

WARNING
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.

When the conditions for automatic engine switch-off are fulfilled only during a stationary phase, the
engine can also switch off subsequently, e.g. after switching off the defrost function.
Conditions for an automatic restart
The engine can start automatically under the following conditions:
If the temperature inside the vehicle substantially increases or decreases.
If the vehicle starts rolling.
If the electrical voltage of the 12-volt vehicle battery drops.
If the steering wheel is moved.
As a general rule, the engine always starts again automatically when required by the detected
situation and for the vehicle.
Conditions that require a manual engine start
The engine must be started manually in the following conditions:
If the driver door is opened.
If the bonnet is opened.
Manually deactivating and activating the start/stop system
Press the button in the centre console ⇒ Fig. 102  to deactivate the system manually. If the
start/stop system has been deactivated, the indicator lamp in the button lights up.
Press the button in the centre console again ⇒ Fig. 102  to activate the system manually once
more.

If the problem persists, switch off Front Assist and go to a qualified workshop.
Lane keeping system (Lane Assist)
Introduction
This chapter contains information on the followingsubjects:
⇒ Driving with the lane keeping system 
⇒ Troubleshooting 
The lane keeping system (Lane Assist) helps the driver stay in lane.
Using a camera in the windscreen, the lane departure warning system detects lane markings on the
road. If your vehicle moves too close to a recognised lane marking, the system will warn the driver
with a corrective steering intervention. The corrective steering intervention can be overridden by
the driver at any time.
Adaptive lane guidance (depending on vehicle equipment)
The adaptive lane guidance system detects the preferred position in a lane and keeps the vehicle in
this position.
Adaptive lane guidance is switched on and off in the Driver assistance menu in the Infotainment
system ⇒ Vehicle settings menu .
System limits
Use the lane keeping system only on motorways and good main roads.
The system is not active under the following conditions:
The lane keeping system has not detected any lane markings.

WARNING
The intelligent technology used in the lane keeping system cannot overcome the laws of physics, and
functions only within the limits of the system. Always take care when using the lane departure
warning system otherwise you could cause accidents or injuries. The system is not a substitute for
the full concentration of the driver.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Your hands should always be on the steering wheel so that you can steer at any time. The driver is
always responsible for staying in lane.
The lane keeping system cannot recognise all lane markings. Poor road surfaces, road structures or
objects could be recognised incorrectly as lane markings by the lane keeping system. The lane
keeping system should be switched off immediately in these situations.
Follow the information on the instrument cluster display and respond according to the commands.

Temporarily switching off the lane keeping system
Switch off the lane keeping system in the following situations:
Very sporty driving.
In poor weather conditions and when driving on poor roads.
In roadworks and before crests in the road.
Driver intervention prompt
In the absence of any steering input, the system prompts the driver with acoustic warnings and a
display on the instrument cluster display to take over active steering.
If the driver does not respond, the system will give another warning by initiating a quick jolt of the
brake before switching to passive mode or activating Emergency Assist (with some equipment
levels).
Steering wheel vibration
The following situations can lead to vibration of the steering wheel:
If the corrective steering intervention is not sufficient to keep the vehicle in its lane.
If the system can no longer detect a lane during a significant steering intervention.

If there is a system fault, the lane keeping system can deactivate itself automatically.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction 
No camera visibility, error message, system switches itself off
Clean the windscreen ⇒ Caring for and cleaning the vehicle exterior .
Check whether any damage is visible on the windscreen in the camera's field of view.
The system is not responding as expected
Regularly clean the camera's field of view, and keep it free from snow and ice.
Do not cover the camera's field of view.
Check the area of the windscreen that is in the camera's field of view for damage.
Do not fit any objects to the steering wheel.
Traffic Jam Assist
Traffic Jam Assist helps the driver to keep in lane, and also provides assistance when following other
vehicles in congestion or slow-moving traffic.
