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.

The discharged vehicle battery must be properly connected to the vehicle's electrical system.
The vehicles must not touch. Otherwise electricity could flow as soon as the positive terminals are
connected.
Ensure that the battery clamps have good metal-to-metal contact with the battery terminals.
If the engine does not start immediately, switch off the starter after about 10 seconds and try again
after about half a minute.
The steps should only be carried out in the specified order.
Attaching the jump leads
•Switch off the ignition in both vehicles ⇒ Starting and stopping the engine.
•If necessary, open the battery cover in the engine compartment ⇒ Vehicle battery.
•Connect one end of the red jump lead to the positive terminal ⇒ Fig. 171⊕ or ⇒ Fig. 172⊕ in
the vehicle with the discharged battery Ⓐ ⇒.
•Connect the other end of the red jump lead to the positive terminal ⊕ in the vehicle providing
assistance Ⓑ.
•In vehicles without start/stop system: connect one end of the black jump lead to the negative
terminal ㊀ in the vehicle providing assistance Ⓑ ⇒ Fig. 171.
•In vehicles with start/stop system: connect one end of the black jump lead Ⓧ to a suitable
earth connection, to a solid metal part that is securely bolted onto the cylinder or to the cylinder
block itself ⇒ Fig. 172.
•Connect the other end of the black jump lead Ⓧ to a solid metal component bolted on to the
engine block, or onto the engine block in the vehicle with the discharged battery. Do not
connect it to a point near the battery Ⓐ ⇒.
•Position the leads in such a way that they cannot come into contact with any moving parts in the
engine compartment.
Starting the engine
•Start the engine of the vehicle providing assistance and let it run at idle.
•Start the engine of the car with the discharged vehicle battery and wait two or three minutes
until the engine is running smoothly.
Removing the jump leads
•Before disconnecting the jump leads, switch off the dipped beam headlights if they are switched
on.
•Turn on the heater blower and rear window heater in the vehicle battery with the discharged
battery. This helps minimise the voltage peaks generated when the leads are disconnected.
•With the engines running, disconnect the jump leads in the exact reverse order to the
instructions given above.
•Close the battery cover.
Tow-starting and towing
 Introduction
This chapter contains information on the followingsubjects:
⇒  Notes on tow-starting
⇒ Notes on towing
Jump starting the vehicle incorrectly can cause the battery to explode, which can lead to
serious 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.
•Always wear suitable eye protection and never lean over the vehicle battery.
•Attach the connector cables in the correct order – the positive cable first, followed by the
negative.
•Never connect the negative cable to parts of the fuel system or to the brake lines.
•The non-insulated parts of the battery clamps must not be allowed to touch. The jump lead
attached to the positive vehicle battery terminal must not touch metal parts of the vehicle.
•Check the window on the vehicle battery using a torch if necessary. If the display is light
yellow or colourless, do not jump start the vehicle. Seek expert assistance.
•Avoid electrostatic discharge in the vicinity of the vehicle battery. The gas emitted from the
vehicle battery could be ignited by sparks.
•Do not use jump leads to start the engine if the vehicle battery is damaged or if it is or has
ever been frozen.
WARNING

•Switch on the ignition and the hazard warning lights.
•Once both vehicles are in motion, release the clutch.
•As soon as the engine starts, press the clutch and put the gear into neutral. This helps to
prevent driving into the towing vehicle.
However, if the vehicle still has to be tow-started (automated manual
gearbox):
•Switch on the ignition and the hazard warning lights.
•Place the selector lever in position N.
•When both vehicles are in motion and the brake pedal indicator lamp goes out, move the
selector lever to position D.
•As soon as the engine starts, press the brake pedal and move the selector lever to position N.
This helps to prevent driving into the towing vehicle.
Notes on towing
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Tow rope or tow bar
It is easier and safer to tow a vehicle with a tow bar. Only use a tow rope if you do not have a tow
bar.
The tow rope should be slightly elastic to reduce the strain on both vehicles. It is advisable to use a
tow rope made of synthetic fibre or similarly elastic material.
Only attach the tow rope or tow bar to the specially provided towing eyes or to the towing bracket.
When a vehicle with a manual gearbox has to be towed:
Check whether the vehicle can be towed ⇒ When should your vehicle not be towed?.
•Move the gear stick to neutral ⇒ Changing gear.
•Do not allow the vehicle to be towed at speeds faster than 50 km/h (30 mph).
•Do not have the vehicle towed further than 50 km (30 miles).
When a vehicle with an automated manual gearbox has to be towed:
Check whether the vehicle can be towed ⇒ When should your vehicle not be towed?
•Switch on the ignition.
•Move the selector lever to N⇒ Changing gear.
•Check whether the automated manual gearbox is really in neutral. To do this drive the car a few
metres as a test. The automated manual gearbox is in neutral if the vehicle can be easily
moved.
•Seek expert assistance if the automated manual gearbox cannot be put into neutral ⇒.
•Do not allow the vehicle to be towed at speeds faster than 50 km/h (30 mph).
•Do not have the vehicle towed further than 50 km (30 miles).
•If a breakdown truck is used, the vehicle must be towed with the front wheels raised.
When should your vehicle not be towed?
•If, due to damage, the vehicle gearbox no longer contains any lubricant.
•If the automated manual gearbox cannot be put into neutral ⇒.
•If the distance to be towed is further than 50 km - applies to vehicles with an automated manual
gearbox only.
•If the steering function or the operating clearance of the wheels cannot be ensured, e.g. after an
accident.
The vehicle can only be towed when the handbrake and steering lock are not engaged.
Fitting the front towing eye
When tow-starting, unburnt fuel can enter the catalytic converter and damage it.
NOTICE
Never tow a vehicle with automated manual gearbox if the automated manual gearbox cannot
be put into neutral. Otherwise, the gearbox and engine can suffer considerable damage.
