Convenience turn signal
To operate the convenience turn signal, push the turn signal and main beam lever up or down to
the point where you meet resistance and then release the lever. The turn signal flashes 3 times.
To cancel the convenience turn signal, immediately move the lever in the opposite direction up to
the pressure point and then release it.
The convenience turn signal can be activated and deactivated in the Infotainment system in
the Vehicle settings menu ⇒ Operation and display in the Infotainment system:
The hazard warning lights also work when the ignition is switched off ⇒ In an emergency.
Some settings can be stored in the user accounts of the personalisation function and
therefore change automatically when the user account changes ⇒ Personalisation.

The electric sun blind works when the ignition is switched on.
When the glass roof is fully tilted, the sun blind is automatically moved to a ventilation position. The
sun blind remains in the ventilation position even after the glass roof has closed.
Opening and closing the sun blind
The buttons ⇒ Fig. 108① or ② have two positions. In the first position the sun blind can be
completely or partially opened or closed.
In the second position, the sun blind automatically moves to the final position when the button is
pressed briefly. Press the button again to stop the one-touch function.
•Opening the sun blind: push button ① to position one. One-touch function: push button ①
briefly to position two.
•Closing the sun blind: push button ② to position one. One-touch function: push button ②
briefly to position two.
•Stopping the one-touch function when opening or closing the blind: push button ① or ② again.
The sun blind can be operated several minutes after the ignition has been switched off, provided
that the driver door and front passenger door are not opened.
Roll-back function of the sun blind
The roll-back function can reduce the risk of crush injury when closing the sun blind ⇒. The
glass roof or sun blind will open again immediately if the sun blind is unable to close because it is
stiff or obstructed.
•Check to see why the sun blind has not closed.
•Try to close the sun blind again.
•The sun blind will open again immediately if it is still unable to close because it is stiff or
obstructed. After opening, the sun blind can be closed again within a short period of time
without the roll-back function.
•If the sun blind still cannot be closed, close it without the roll-back function.
Closing the sun blind without the roll-back function
•Within approximately five seconds of the roll-back function being switched off, press and hold
button ⇒ Fig. 108② until the sun blind has closed completely.
•The sun blind will now close without the roll-back function.
•Please go to a qualified workshop if the sun blind still cannot be closed.
When the glass roof is open, the electric sun blind can be closed only up to the front edge of
the glass roof.

Tips and usage notes
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following tips and operating information will help you use the system correctly.
m/k/a995MK Vehicles with DSG dual clutch gearbox: the selector lever must be in the
Tiptronic position ⇒ Changing gear using Tiptronic.
No recommended gear is indicated if the most suitable gear is already selected. The currently
selected gear is displayed.
Information on cleaning the particulate filter
The engine management system recognises when the particulate filter is becoming saturated and
supports regeneration of the particulate filter by recommending the most suitable gear when driving.
Compared with normal driving, this may mean driving with an increased engine speed ⇒ Particulate
filter.
Driving in the correct gear can help to reduce fuel consumption.
Gear-change indicator display goes out when the clutch is depressed in vehicles with a
manual gearbox or when Tiptronic position is deselected in vehicles with a DSG dual clutch
gearbox.
Driving economically
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The fuel consumption, pollution and
wear of the engine, brakes and tyres
are reduced by an appropriate driving
style. A few tips are provided below
which will help you protect the
environment and also save money.
Fig. 116 Fuel consumption in litres per 100 km at two different outside temperatures.
Think ahead when driving
The fuel consumption will increase if you do not adopt a steady driving style. Keeping a close eye
on the traffic can help to avoid frequent acceleration and braking. Keeping a sufficient distance from
the vehicle in front will help you anticipate the driving situation.
Use the cruise control system where possible ⇒ Cruise control system (CCS).
With a gear engaged, allow the vehicle to come to a halt by itself to make use of the engine braking
effect, e.g. when approaching traffic lights.
Using freewheeling
m/k/a995MKVehicles with a DSG dual clutch gearbox: When the selector lever is in
position D/S and neither the accelerator nor the brake pedal is depressed, the vehicle will roll
(coast) with practically no energy being consumed.
With the engine-off coasting function, the engine is not just disengaged, but is also switched off.
Driving with DSG dual clutch gearbox ⇒ Driving with DSG dual clutch gearbox.
Change gears in an energy-saving way
Shifting up early at an engine speed of 2,000 rpm will save energy. Do not drive gears to the limit
and avoid high revs.
The gear-change indicator is only designed to assist the driver and cannot replace the
driver's own judgement.
•The driver has full responsibility for selecting the correct gear in all situations (e.g.
when overtaking, driving up and down hills ⇒ Trailer towingand when towing a trailer).
CAUTION
®
®®
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.
