Refuelling the vehicle
WARNING ‑ Risk of fire or explosion caused by fuel
Fuels are highly inflammable.
You must avoid fire, naked flames, creating sparks and smoking.
Before refuelling, switch off the engine and auxiliary heating if your vehicle is equipped with auxiliary heating.
WARNING Risk of injury from fuel
Fuels are poisonous and harmful 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.
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 cause sparks and thereby ignite fuel vapours.
Touch the metal vehicle body before opening the fuel filler cap or touching the pump nozzle.
This discharges any electrostatic charge that may have built up.
WARNING Risk of fire from fuel mixture
Vehicles with a diesel engine:
If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel.
While the engine is running, component parts in the exhaust system may overheat without warning.
Never refuel using petrol.
Never mix petrol with diesel fuel.
NOTE Damage caused by the wrong fuel
Fuel that does not conform to the required quality can lead to increased wear as well as damage to the engine and exhaust system.
Only use the fuel recommended.
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 premium-grade unleaded fuel that conforms to 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.
Do not refuel using:
Diesel
E85, E100
Petrol containing methanol (M15, M30, M85, M100)
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 Damage caused by the wrong fuel

Topping up the windscreen washer system
WARNING Danger of burns from hot component parts in the engine compartment
Certain component parts in the engine compartment may be very hot, e.g. the engine, the radiator and parts of the exhaust system.
Let the engine cool down and only touch the component parts described below:
WARNING Danger of burns when opening the engine bonnet
If you open the engine bonnet when the engine has overheated or during a fire in the engine compartment, you could come into contact with hot gases or other escaping operating fluids.
Before opening the engine bonnet, allow the engine to cool down.
In the event of a fire in the engine compartment, keep the engine bonnet closed and call the fire service.
WARNING ‑ Risk of fire and injury due to windscreen washer concentrate
Windscreen washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine component parts or the exhaust system.
Make sure that no windscreen washer concentrate spills out next to the filler opening.
Remove cap by the tab.

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.
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 side windows and sliding sunroof are completely closed.
The blower for the ventilation/heating is switched off.
The windscreen wiper switch is in position
. In car washes with a towing mechanism: neutral
is engaged. The key is at a distance of at least 3 m away from the vehicle, otherwise the tailgate could open unintentionally.
If, after the car wash, you remove the wax from the windscreen and wiper rubber, this will prevent smearing and reduce wiper noise.
