Unintentional vehicle movements during service work can cause serious injury.
•Never work underneath a vehicle if it is not secured against rolling away. If you are
working underneath the vehicle while the wheels are on the ground, the vehicle must be
on a level, the wheels must be blocked and the vehicle key must be removed from the
ignition lock.
•If you have to work underneath the vehicle, use suitable stands to provide extra support
for the vehicle. The vehicle jack is not sufficient for this task and can fail, which can lead to
serious injuries.
•The start/stop system must have been deactivated.
WARNING
The engine compartment of any motor vehicle is a dangerous area. Serious injuries can be
sustained here.
•The utmost care and attention must be paid when carrying out any work and you must
follow the general safety rules. Never take any risks.
•Never do any work on the engine or in the engine compartment unless you know exactly
how to carry it out. If you are uncertain of what to do, the work should be carried out by a
qualified workshop. Serious injuries can result from work that has not been carried out
properly.
•Never open the bonnet if you see steam or coolant escaping from the engine
compartment. Hot steam or coolant can cause serious burns. Always wait until you can no
longer see or hear steam or coolant coming from the engine compartment.
•Always allow the engine to cool down before opening the bonnet.
•Hot parts of the engine or exhaust system can burn the skin.
•Before opening the bonnet once it has cooled down:
- Apply the handbrake fully and move the selector lever to position N or move the
manual gear lever to the neutral position.
- Remove the vehicle key from the ignition lock.
- Always keep children away from the engine compartment and never leave the
vehicle unattended.
•The engine cooling system is under pressure when the engine is hot. Never open the cap
of the coolant expansion tank when the engine is hot. Coolant may spray out and cause
serious burns and injuries.
- After cooling, turn the cap slowly and very carefully anticlockwise while exerting
some downwards pressure on the cap.
- Always protect the face, hands and arms from hot coolant or steam with a large,
thick cloth.
•When refilling, do not spill any service fluids on engine components or on the exhaust
system. The spilt service fluids can start a fire.
WARNING
High voltages in the electrical system can cause electric shocks, burns, serious injuries and
death!
•Never short circuit the electric system. The vehicle battery could explode.
•Please note the following guidelines to help reduce the risk of an electric shock and
serious injuries while the engine is running or being started:
- Never touch the electrical wiring of the ignition system.
WARNING
Several electrical consumers could share a single fuse. Conversely, a single consumer could have
more than one fuse.
Therefore fuses should only be replaced when the cause of the fault has been rectified. If a new
fuse blows shortly after insertion, have the electrical system checked by a qualified workshop as
soon as possible.

First read and observe the introductoryinformation and safety warnings⇒
Introduction
Fuses must always be replaced by a new fuse with the same amp rating (same colour and
markings) and size.
High voltages in the electrical system can cause electric shocks, serious burns and death.
•Never touch the electrical wiring of the ignition system.
•Avoid causing short circuits in the electrical system.
WARNING
Using unsuitable or repaired fuses and bridging an electrical circuit without fuses can cause a
fire and serious injuries.
•Never fit fuses that have a higher fuse protection limit. Fuses must always be replaced by
a new fuse with the same amp rating (same colour and markings) and size.
•Never repair a fuse.
•Never use a metal strip, paper clip or similar objects to replace a fuse.
WARNING
•To avoid damage to the electrical system in the vehicle, switch the ignition, the lights and
all electrical consumers off and remove the vehicle key from the ignition before changing a
fuse.
•You can damage another position in the electrical system by using a fuse with a higher
amp rating.
•Fuse boxes must be protected from dirt and moisture when opened. Dirt and moisture in
the fuse boxes can damage the electrical system.
