Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.
Apply the handbrake firmly Braking, stopping and parking.
Turn the light switch to position 0 Lights.
Shift the turn signal lever to neutral Lights.
Automated manual gearbox: move the selector lever to D or R Changing gear.
Stop the engine and remove the vehicle key from the ignition Starting and stopping the
engine.
Manual gearbox: select a gear Changing gear.
Leave the defective bulbs to cool down.
Check to see if a fuse has blown Fuses.
Follow the instructions to change the affected bulb . Always use identical bulbs with the
same designation. The designation is inscribed on the bulb, either on the glass part or on
the base.
Do not touch the glass part of the bulb with unprotected fingers. The heat of the bulb would
cause the fingerprint to evaporate and condense on the reflector. This will impair the
brightness of the headlight.
After changing the bulb, check to ensure that the bulb is working properly. If the bulb is not
working properly, the bulb may not have been inserted properly or may have failed again,
or the connector may have been inserted incorrectly.
Any time you change a bulb in the front of the vehicle, the headlight settings should be
checked by a qualified workshop.
Information on changing bulbs
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
Always carry out the following actions for changing a bulb in the given order ⇒:
Accidents can occur if roads are not sufficiently illuminated and other road users have
difficulty seeing the vehicle, or cannot see it at all.
WARNING
Changing the bulb incorrectly can cause accidents and serious injuries.
•When working in the engine compartment, always read and observe the safety warnings
⇒ Preparation for working in the engine compartment. The engine compartment of any
motor vehicle is a dangerous area. Serious injuries can be sustained here.
•H4, HB4 and H7 bulbs are pressurised and could explode when they are being changed.
•Only change the defective bulb once it has had time to cool down completely.
•Never change a bulb unless you are familiar with the procedure. If you are uncertain of
what to do, the work should be carried out by a qualified workshop.
•Do not touch the glass part of the bulb with unprotected fingers. When the light is switched
on, heat will cause fingerprints to evaporate on the bulb, which in turn will cause the
reflector to dim.
•There are sharp-edged parts in the headlight housing in the engine compartment and on
the tail light cluster housing. Protect your hands when changing bulbs.
WARNING
Damage to the electrical system could be caused by water entering the system if the rubber
cover on the headlight housing is not properly mounted.
NOTICE
Ignoring any of the items on this important safety checklist can lead to accidents and severe
injuries.
•Always follow the instructions in the checklist and observe the general safety procedures.
WARNING
Always take care when removing or fitting lights to prevent damage to the paintwork or to
other vehicle parts.

How to start the engine using jump leads
Fig. 171 How to connect the jump leads when starting vehicles without start/stop system:
discharged battery Ⓐ and battery providing assistance Ⓑ
Fig. 172 How to connect the jump leads when starting vehicles with start/stop system: discharged
battery Ⓐ and battery providing assistance Ⓑ
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicle with discharged battery that is being jump-started.
Vehicle with vehicle battery that is supplying power and jump-starting the other vehicle.
Suitable earth connection. A solid metal part that is firmly bolted to the engine block, the
engine block itself or, where fitted, the screwed-in towing eye at the front ⇒ Tow-starting and
towing.
Using the jump leads incorrectly or completing the jump start procedure incorrectly can cause
the battery to explode, which can lead to severe injuries. Please note the following in order to
reduce the risk of the battery exploding:
•All work on the vehicle battery and the electrical system can cause serious chemical
burns, fire and electric shocks. Always read the warnings and safety information before
carrying out any kind of work on the vehicle battery ⇒ Vehicle battery.
•The vehicle battery providing assistance must have the same voltage as the discharged
vehicle battery (12 volt) and approximately the same capacity (see markings on battery).
•Never charge a vehicle battery once it has been frozen. Discharged vehicle batteries can
even freeze at temperatures of around 0°C (+32°F).
•The battery should be replaced if it is or has ever been frozen.
•A highly explosive mixture of gases is given off when the vehicle battery is jump started.
Always keep fire, sparks, naked flames and lit cigarettes away from the vehicle battery.
Never use a mobile telephone when the jump leads are being connected or disconnected.
•Only charge the battery in a well-ventilated space as the battery emits a highly explosive
mixture of gases when the vehicle is being jump started.
•Position the jump leads so that they never come into contact with any moving parts in the
engine compartment.
•Never confuse the negative and positive terminals or connect the jump leads incorrectly.
•Observe the jump lead manufacturer's instructions.
WARNING
Please note the following in order to avoid considerable damage to the vehicle electrical
system:
•A short circuit can be caused if the jump leads are wrongly connected.
•The vehicles must not touch each other, otherwise electricity could flow as soon as the
positive terminals are connected.
