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 ignite fuel vapour.
Before you open the fuel filler cap or take hold of the pump nozzle, touch the metallic vehicle body.
To avoid creating another electrostatic charge, do not get into the vehicle again during the refuelling process.
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 petrol that conforms to European EN 228, or an equivalent specification.
Fuel of this specification may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel.
Never refuel with one 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, E20, E85, E100
petrol with more than 3% methanol by volume, e.g. M15, M30
petrol with additives containing metal
If you have accidentally refuelled 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.
If you have added too much fuel because of a defective filling pump, for instance:
Do not switch the ignition on.
Consult a qualified specialist workshop.
NOTE Fuel may spray out when you remove the fuel pump nozzle
Only fill the fuel tank until the pump nozzle switches off.
Requirements:
The vehicle is unlocked.
Do not get into the vehicle again during the refuelling process. Otherwise, electrostatic charge could build up again.
Observe the notes on operating fluids and fuel.
The recommended octane number for your vehicle can be found on the information label in the fuel filler flap.
Press on the back area of fuel filler flap .
. Turn the fuel filler cap anti-clockwise and remove it.
Insert fuel filler cap from above into bracket .
. Completely insert the pump nozzle into the tank filler neck, hook in place and refuel.

WARNING Risk of burns when opening the bonnet
If you open the bonnet when the engine has overheated or when there is a fire in the engine compartment, the following situations may occur:
You could come into contact with hot gases.
You could come into contact with other hot, escaping operating fluids.
Before opening the bonnet, allow the engine to cool down.
In the event of a fire in the engine compartment, keep the bonnet closed and call the fire service.
WARNING Risk of injury due to moving parts
Components in the engine compartment may continue running or start up suddenly, even if the ignition is switched 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 from automatic braking
If one of the following functions is switched on, the vehicle brakes automatically in certain situations:
Active Brake Assist
Active Distance Assist DISTRONIC
HOLD function
Active Parking Assist
To avoid damage to the vehicle, deactivate these systems in the following or similar situations:
during towing
in a car wash
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 is deactivated.
The HOLD function is switched off.
The 360° Camera is switched off.
The vehicle is locked and the door handles retracted.
The side windows and sliding sunroof are completely closed.
The blower for the ventilation and heating is switched off.
The windscreen wiper switch is in position
. The key is at a minimum distance of 6 m away from the vehicle. Otherwise the boot lid or a door could open unintentionally.
For car washes with a conveyor system:
Neutral
is engaged. The vehicle is locked from inside.
Do not make any hand movements in the area of the overhead control panel or deactivate More the Sliding sunroof and roller sunblind option in the settings for the MBUX interior assistant.
If, after the car wash, you remove the wax from the windscreen and wiper rubbers, this will prevent smearing and reduce wiper noise.
