Electric window roll-back function
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The roll-back function for the electric windows can reduce the risk of crush injuries when the
windows are closing.
If the window is not able to close because it is stiff or because of an obstruction, the window will
immediately open again ⇒.
•Check to see why the window has not closed.
•Try to close the window again.
•If the window closing process is interrupted again, the roll-back function will be disabled for a
few seconds.
•If the window still cannot be closed, it will stop at the corresponding position. To close the
window without the roll-back function, press the button again within a few seconds ⇒.
Careless or unsupervised use of the electric windows can cause serious injuries.
•The electric windows should be opened or closed only when you are sure that nobody
is in their operating area.
•Never leave children or people requiring assistance alone in the vehicle when the
vehicle is locked. The windows can no longer be opened in an emergency.
•Always take all vehicle keys with you every time you leave the vehicle. The windows
can still be operated using the buttons in the doors for a short time after the ignition
has been switched off, provided that the driver door and front passenger door are not
opened.
•When transporting children on the rear bench seat, the rear electric windows should
always be deactivated using the safety button so that they cannot be opened or closed.

NOTICE
Troubleshooting
Washer fluid level too low. Fill up the washer fluid reservoir as soon as possible ⇒ Washer
fluid.Fault in the rain/light sensor. Switch the ignition on and off. If the indicator lamp still lights
up permanently after you switch the ignition back on, seek expert assistance.Fault in
windscreen wipers. Switch the ignition on and off. If the indicator lamp still lights up permanently
after you switch the ignition back on, seek expert assistance.
Changes in the response of the rain/light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light
sensor ⇒ Vehicle overviews include:
•Damaged wiper blades: a film of water or smears caused by damaged wiper blades can
increase the time the wipers are switched on, can shorten the length of the intervals between
wipes or cause the wipers to run quickly and continuously.
•Insects: insects hitting the windscreen surface can cause the wipers to be activated.
•Salt deposits: in winter, salt deposits on the windscreen can cause the wipers to continue to
wipe the windscreen when it is almost dry.
•Soiling: dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an
automatic car wash) can cause the rain/light sensor to become less sensitive and react too
slowly, or prevent it from reacting at all. Clean the sensitive surface of the rain/light sensor
⇒ Caring for and cleaning the vehicle exterior at regular intervals and inspect the wiper blades
for damage.
•Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the
windscreen is impacted by a stone. The rain/light sensor will then register the reduction in
sensitivity of the surfaces and adjust accordingly. The size of the crack can affect the way in
which the rain/light sensor activates the wipers.
We recommend that you use an alcohol-based glass cleaner to remove wax and polish.
The wipers will try to wipe away any obstacles that are on the windscreen. The wipers will
stop moving if the obstacle blocks their path. Remove the obstacle and switch the wipers back on
again.
Mirrors
Introduction
This chapter contains information on the followingsubjects:
⇒ Interior mirror
⇒ Exterior mirrors
You can use the exterior mirrors and the interior mirror to observe traffic behind you and adjust
driving style accordingly.
For safety reasons it is important that the driver positions the exterior and interior mirrors correctly
before starting a journey ⇒.
Looking in the exterior mirrors and the interior mirror does not allow the driver to see the entire side
and rear area of the vehicle. The area that cannot be seen is known as the blind spot. There may
be objects and other road users in the blind spot.
Adjusting the exterior and interior mirrors while driving may cause the driver to become
distracted. This can lead to accidents and serious injuries.
•Exterior and interior mirrors should only be adjusted when the vehicle is stationary.
•When parking, changing lane, or performing an overtaking or turning manoeuvre,
always pay careful attention to the area around the vehicle as objects and other road
users may be located in the blind spot.
•Always ensure that the mirrors are positioned correctly and that the rear view is not
restricted by ice, snow, condensation or any other objects.
WARNING
If you estimate the distance from traffic behind you incorrectly, you can cause accidents
and serious injuries.
•Curved mirrors (convex or aspheric) enlarge the field of vision and can make objects in
the mirror seem smaller and further away than they actually are.
•Using curved mirrors to estimate the distance from other vehicles behind you when
changing lanes can provide inaccurate results and can lead to accidents and severe
injuries.
•Whenever possible, use the interior mirror to check the exact distance between your
vehicle and following traffic or other objects.
•Ensure that you have a good view to the rear of the vehicle.
WARNING
m/k/a995MK Vehicles with manual gearbox: change from first to second gear immediately
after setting off. Change to higher gears rapidly.
m/k/a995MK Vehicles with DSG dual clutch gearbox: accelerate slowly and avoid using the
kickdown function.
Gear-change indicator ⇒ Gear-change indicator.
Eco driving profile ⇒ Driving profile selection and 4MOTION Active Control.
Avoid full throttle
Never fully use the maximum speed of the vehicle. Driving at excessive speeds, e.g. above 130
km/h on the motorway, will increase air resistance and thus the amount of force needed to move
the vehicle.
Reduce idling
Drive off immediately with low revs. If you are stopped for a long period, do not allow the engine to
idle but switch it off, e.g. when in a traffic jam or at a railway crossing.
In vehicles with an activated start/stop system, the engine will switch off automatically when the
vehicle is stopping and when the vehicle is stationary ⇒ Start/stop system .
Refuel with moderation
A full fuel tank increases the weight of the vehicle. A fuel tank that is half to three quarters full is
sufficient for urban journeys in particular.
Avoid short journeys
A cold engine has a very high fuel consumption. The optimum operating temperature is reached
only after driving a few miles. The fuel consumption is above average at very low ambient
temperatures, e.g. in winter ⇒ Fig. 116. Plan journeys economically and combine short distances.
Carry out regular maintenance
Regular maintenance is an essential prerequisite for economical driving and increases the service
life of the vehicle.
Observe the correct tyre pressures
An inadequate tyre pressure does not just mean greater wear, but also increases the rolling
resistance of the tyres and thus the fuel consumption. Use optimised rolling resistance tyres.
Adjust the tyre pressure according to the vehicle load. Observe the information on the tyre pressure
sticker ⇒ Useful information about wheels and tyres
Tyre Pressure Loss Indicator or Tyre Pressure Monitoring System ⇒ Tyre monitoring systems.
Use low viscosity engine oil
Fully synthetic engine oils with a low viscosity decrease frictional resistance in the engine and
spread better and more quickly, especially for cold starts.
Do not drive with unnecessary loads in the vehicle
You can reduce fuel consumption by clearing out the luggage compartment before setting off, for
example by removing empty drink crates or unused child seats.
In order to keep the drag coefficient of the vehicle as low as possible, remove attachments and
add-on parts such as ski, bicycle or roof carriers after use.
Save electrical energy
The alternator is driven by the engine and generates power for convenience consumers such as the
air conditioning system, window heating and ventilation. Saving electrical energy is easy, e.g.:
•At high ambient temperatures, ventilate the car before starting a journey and drive a short
distance with open window. Only then switch on the air conditioning system.
•Switch off convenience systems as soon as they have served their purpose.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road
and traffic conditions.
WARNING
Warning lights and text messages are shown on the instrument cluster display. These warnings
may be accompanied by acoustic signals.
Front brake pads worn. Go to a qualified workshop immediately. All brake pads should be
checked and renewed as necessary.
Malfunction in the brake system
A brake circuit may have failed if you have to reduce speed and the vehicle does not brake as
normal (sudden increase in braking distance). This is indicated by the warning lamp and in
some cases by a text message. Go to the nearest qualified workshop immediately to have the fault
corrected. Drive at low speed when doing this and anticipate much longer braking distances and an
increase in the pressure required on the pedal.
Starting and stopping the engine
Introduction
This chapter contains information on the followingsubjects:
⇒ Ignition lock
⇒ Starter button
⇒ Starting the engine
⇒ Stopping the engine
⇒ Electronic immobiliser
⇒ Troubleshooting
Push-starting or tow-starting
For technical reasons, your vehicle must not be push-started or tow-started. Use jump leads to
start the engine instead ⇒ Jump starting.
Ignition lock
Switching the engine off while the vehicle is moving makes it more difficult to stop the
vehicle. This can lead to loss of control of the vehicle and to accidents and severe injuries.
•Braking and steering support systems, the airbag system, the belt tensioners and other
items of safety equipment in the vehicle are only active when the engine is running.
•Never switch the engine or ignition off while the vehicle is in motion.
WARNING
The risk of serious injury can be reduced with the engine running or when starting the
engine.
•Never start or run the engine in unventilated or closed rooms. The exhaust fumes
contain carbon monoxide, an odourless and colourless toxic gas. Carbon monoxide
can cause people to lose consciousness. It can also cause death.
•Never start or run the engine if oil, fuel or any other highly flammable fluids are under
or near the vehicle, or are leaking out of the vehicle, e.g. as the result of damage.
•Never leave the vehicle unattended with the engine running, particularly if a gear or
position has been selected. The vehicle could move suddenly or something
unexpected may happen that may cause damage, fire and serious injuries.
•Never use a start booster. Start boosters may explode and cause the engine to
suddenly run at high revs.
WARNING
The components of the exhaust system become very hot. This can cause fires and serious
injuries.
•Never park the vehicle where parts of the exhaust system can come into contact with
inflammable material underneath the vehicle, e.g. undergrowth, leaves, dry grass, spilt
fuel.
•Never apply additional underseal or anti-corrosion coatings to the exhaust pipes,
catalytic converters, heat shields or particulate filter.

can cause serious injury.
•Never leave children or people requiring assistance alone in the vehicle when the
vehicle is locked. They could become trapped in the vehicle in an emergency and may
not be able to get themselves to safety. For example, locked vehicles may be subjected
to very high or very low temperatures depending on the season. This can cause
serious injuries and illness or fatalities, especially among small children.
•Never remove the vehicle key from the ignition lock when the vehicle is in motion. The
steering column lock may be activated and you will no longer be able to steer the
vehicle.
•The key bit in the vehicle key needs to be folded out fully and locked in position.
•Only attach light objects weighing under 100 g to the vehicle key.
WARNING
The 12-volt vehicle battery may run down and prevent the motor from restarting if the
ignition is switched on while the engine is switched off.
•Always switch off the ignition before leaving the vehicle.
NOTICE
Automatic ignition switch-off
The ignition switches off automatically after a short time if the driver moves away from the vehicle
with the vehicle key when the ignition is switched on. If the dipped beam headlights were switched
on at the time, the side lights will remain switched on for approximately 30 minutes. The side lights
can be switched off manually ⇒ Lights or by locking the vehicle ⇒ Central and manual locking.
Once the vehicle detects that the driver is absent when the engine stop is active, the ignition will
switched off automatically after a certain period of time.
Automatic ignition switch-off in vehicles with a start/stop system
When all the following conditions are fulfilled at the same time, the vehicle ignition will be switched
off automatically when engine stop is active and when the vehicle is stationary:
•The driver removes their seat belt.
•No pedals are depressed.
•The driver door is opened.
If the ignition is deactivated automatically while the dipped beam headlights are switched on ,
the side lights remain switched on for around 30 minutes.
The side lights can be switched off manually or will go off when the vehicle is locked.
Engine restart function
If no valid vehicle key is detected in the vehicle interior once the engine has been switched off, the
engine can be restarted within approximately 5 seconds. A corresponding message appears on the
instrument cluster display.
After this time, the engine cannot be re-started without a valid vehicle key in the vehicle interior.
Before leaving the vehicle, always switch off the ignition manually and observe any
information shown in the instrument cluster display.
Leaving the vehicle stationary for long periods with the ignition switched on can discharge
the 12-volt vehicle battery so that the engine can no longer be started.
