Before carrying out maintenance or repair work, you must read the relevant sections of the technical documentation relating to maintenance and repair measures, e.g.

• Operating Instructions and workshop information

In particular, also familiarise yourself with the legal regulations, e.g.:

• work safety and accident prevention regulations

You could otherwise fail to recognise dangers and injure yourself or others.

You must secure the vehicle on axle stands of sufficient load bearing capacity if work is being carried out beneath it.

Never use the vehicle jack instead of stands. There is a danger that the jack could give way, the vehicle could slip and you or other persons could be seriously injured or property could be damaged.

The vehicle jack is only intended to raise the vehicle for a short time.

Always have maintenance work carried out at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required.

Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. All work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

Do not pull the release lever while the vehicle is in motion. The bonnet could otherwise open.

There is a risk of injury if the bonnet is open, even if the engine is not running.

Some engine components can become very hot.

To avoid the risk of burns, only touch those components described in the Operating Instructions and observe the relevant safety notes.

The radiator fan between the radiator and the engine can start up by itself even if the key has been removed. Keep away from the area of rotation of the fan blades. Otherwise, you could be injured.

Vehicles with a petrol engine:

The electronic ignition system operates with high voltages. For this reason, you must never touch the ignition system components (ignition coil, ignition cables, spark plug connections, test socket) while:

• the engine is running

• the engine is being started

• the ignition is switched on and the engine is being cranked by hand

Vehicles with a diesel engine:

The electronic injector control operates with high voltages. For this reason, you must never touch injection system components while:

• the engine is running

• the engine is being started

• the ignition is switched on

Make sure that nobody can become trapped as you close the bonnet.

When opening the coolant expansion tank, there is a risk of scalding by hot coolant spraying out. The cooling system and the coolant expansion tank are pressurised when the engine is at normal operating temperature. Wear gloves and eye protection.

Only open the coolant expansion tank when the coolant temperature is below 50 .

Coolant contains glycol and is therefore toxic. Do not swallow the coolant. See a doctor immediately if you swallow coolant.

Make sure that coolant does not come into contact with skin, eyes or clothing. In case of contact with eyes, rinse immediately with plenty of clean water. Clean affected areas of skin and clothing with soap and water immediately. Change any affected clothing immediately.

Brake fluid constitutes a health hazard. Do not swallow the brake fluid. See a doctor immediately if you swallow brake fluid.

Make sure that brake fluid does not come into contact with skin, clothing or eyes. Rinse affected areas with plenty of clean water and consult a doctor if necessary.

Always wear gloves and eye protection when topping up brake fluid.

Store brake fluid only in the original closed container and keep it out of the reach of children. Comply with safety regulations when handling brake fluid.

If the boiling point of the brake fluid is too low, vapour pockets may form in the brake system when the brakes are subjected to a heavy load (e.g. on long downhill stretches). This would impair braking efficiency. The vehicle’s stopping distance may then be longer. This increases the risk of an accident.

Have the brake fluid renewed every 2 years.

Washer fluid concentrate is highly flammable.

Fire, naked flames and smoking are therefore prohibited when you are handling washer fluid concentrate.

Vehicles with air heater:

Under the German national road traffic licensing regulations (StVZO), the heat exchanger must be replaced after 10 years.

For safety reasons, Mercedes‑Benz strongly recommends that the heat exchanger be replaced after 10 years at a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required.

Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this purpose. In particular, all work relevant to safety or on safety-related systems must be carried out at a qualified specialist workshop.

When the windscreen wipers are set to intermittent wipe or the rain sensor is active, the windscreen wipers could start moving at any time and injure you or others.

Always remove the key from the ignition lock before replacing the wiper blades.

Wiper blades are wear parts. Change the wiper blades every six months, ideally in the spring and autumn. Otherwise, the windscreen and rear window will not be wiped properly. This may prevent you from observing the traffic conditions, thereby causing an accident.

There is a risk of a short circuit if the positive terminal of the battery comes into contact with vehicle parts when it is connected. This could cause the battery’s highly flammable gas mixture to ignite. This could result in serious injury to yourself or others.

• Do not place any metal objects or tools on the batteries.

• When disconnecting batteries, always disconnect the negative terminal first and then the positive terminal.

• When connecting batteries, always connect the positive terminal first and then the negative terminal.

• Never loosen or disconnect the connection terminals of the batteries when the engine is running.

Free movement of the pedals must not be impaired. This would otherwise jeopardise the operating and road safety of the vehicle.

Make sure that the floor covering is pushed under the carrier of the accelerator pedal and cannot slide between the carrier bar and the accelerator pedal when you install it.

This would otherwise prevent you from depressing the accelerator pedal completely, thereby restricting your vehicle's acceleration, e.g. during overtaking.

Only charge the battery in well-ventilated areas. As the battery is being charged, gases can escape and generate minor explosions, which can injure you and others or may cause damage to the paintwork or acid corrosion on the vehicle.

There is a risk of acid burns during the charging process due to the gases which escape from the battery. Do not, therefore, lean over the battery while it is being recharged.
