Refuelling the vehicle
WARNING Risk of fire or explosion from fuel
Fuels are highly flammable.
Fire, naked flames, smoking and creation of sparks must be avoided.
Switch off the ignition and, if available, the stationary heater, before and while refuelling the vehicle.
WARNING Risk of injury from fuels
Fuels are poisonous and hazardous to your health.
Do not swallow fuel or let it come into contact with skin, eyes or clothing.
Do not inhale fuel vapour.
Keep children away from fuel.
Keep doors and windows closed during the refuelling process.
If you or other people come into contact with fuel, observe the following:
Immediately rinse fuel off your skin with soap and water.
If fuel comes into contact with your eyes, immediately rinse them thoroughly with clean water. Seek medical attention immediately.
If you swallow fuel, seek medical attention immediately. Do not induce vomiting.
Change immediately out of clothing that has come into contact with fuel.
WARNING Risk of fire and explosion due to electrostatic charge
Electrostatic charge can create sparks and thereby ignite fuel vapours.
Before you open the fuel filler cap or take hold of the pump nozzle, touch the metallic vehicle body.
This discharges any electrostatic charge that may have built up.
Do not get into the vehicle again during the refuelling process.
Otherwise, electrostatic charge can build up again.
NOTE Damage caused by the wrong fuel
Vehicles with a petrol engine:
Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.
Only refuel using unleaded, sulphur-free fuel that conforms to European EN 228, or an equivalent specification.
The RON requirement is located in the fuel filler flap.
Fuel of this specification may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel.
Never refuel using any of the following fuels:
diesel
regular petrol with an octane number lower than 91 RON
petrol with more than 10% ethanol by volume, e.g. E15, E30, E85, E100
petrol with more than 3% methanol by volume, e.g. M15, M30
petrol with additives containing metal
If you accidentally refuel with the wrong fuel:
Do not switch the ignition on.
Consult a qualified specialist workshop.
NOTE Do not use diesel to refuel vehicles with a petrol engine
If you have accidentally refuelled with the wrong fuel:
do not switch the ignition on. Otherwise fuel can enter the engine.
Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. The repair costs are high.
Consult a qualified specialist workshop.
Have the fuel tank and fuel lines drained completely.
NOTE Damage to the fuel system caused by overfilled fuel tanks
Only fill the fuel tank until the pump nozzle switches off.
NOTE Fuel may spray out when you remove the fuel pump nozzle
Only fill the fuel tank until the pump nozzle switches off.

Information on washing the vehicle in a car wash
WARNING Risk of an accident due to reduced braking power after washing the vehicle
Braking efficiency is reduced after washing the vehicle.
After the vehicle has been washed, brake carefully while paying attention to the traffic conditions until braking power has been fully restored.
NOTE Damage due to unsuitable car wash
Before driving into a car wash make sure that the car wash is suitable for the vehicle dimensions.
Ensure there is sufficient ground clearance between the underbody and the guide rails of the car wash.
Ensure that the clearance width of the car wash, in particular the width of the guide rails, is sufficient.
To avoid damage to your vehicle when using a car wash, ensure the following beforehand:
Active Distance Assist DISTRONIC and the HOLD function are deactivated.
the 360° Camera or the reversing camera is switched off.
the extendable rear wing is completely retracted.
the side windows and sliding sunroof are completely closed.
the blower for the ventilation/heating is switched off.
the windscreen wiper switch is in position
. the key is at a minimum distance of 3 m away from the vehicle, otherwise the tailgate could open unintentionally.
in car washes with a conveyor system: neutral
is engaged.
In car washes with a conveyor system: if you would like to leave the vehicle while it is being washed, make sure the key is located in the vehicle. The park position 
is otherwise automatically engaged.
If, after the car wash, you remove the wax from the windscreen and wiper rubbers, this will prevent smearing and reduce wiper noise.
