Checking the engine oil level with an oil dipstick

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.

Make sure of the following before performing tasks in the engine compartment:

Switch the ignition off.

Never reach into the danger zone surrounding moving components, e.g. the rotation area of the fan.

Remove jewellery and watches.

Keep items of clothing and hair away from moving parts.

WARNING Risk of burns from hot component parts in the engine compartment

Certain component parts in the engine compartment can be very hot, e.g. the engine, the cooler and parts of the exhaust system.

Allow the engine to cool down and only touch component parts described in the following.

The engine oil becomes dirty during operation, loses quality and also gradually loses volume. Check the oil level regularly and top up the oil or have it changed if necessary.

Regularly check the fluid level and the major assemblies for leaks. If you detect fluid loss, for example, oil drops on the vehicle parking space, consult a qualified specialist workshop as quickly as possible.

Only check the oil level when the engine is at normal operating temperature.
