Some models are delivered without a factory-fitted jack or box spanner. If this is the case, the wheel should be changed by a qualified workshop.
The vehicle jack supplied with the vehicle is only designed for changing a wheel when one vehicle tyre is damaged and has to be replaced. Seek ex-pert assistance if both tyres on one side of the ve-hicle, both tyres on one axle, or all tyres are dam-aged.
Only change the wheel yourself when the car is parked in a safe place, you are familiar with the necessary steps and safety procedures and you have access to all the correct tools. Seek expert assistance if this is not the case.

Preparations for changing a wheel
1"1'11 First read and observe the introductory L-1o:.U information and safety warnings & on page 420.
Checklist
The following actions must always be carried out in the given order in preparation for changing the wheel=>&:
1. In the event of a flat tyre, park your vehicle on a firm and level surface at a safe dis-tance from the flow of traffic.
2. Apply the handbrake =>page 269.
420 I If and when
A wARNING
Changing a wheel can be dangerous, espe-cially when carried out at the side of a road. Please note the following steps in order to re-duce the risk of serious injuries:
• Stop the vehicle as soon as possible and when safe to do so. Park the vehicle at a safe distance from moving traffic in order to carry out the wheel change.
• All passengers and children in particular must be at a safe distance and away from your area of work during the wheel change.
• Switch on the hazard warning lights to warn other road users.
• Check that the surface the vehicle Is parked on Is level and firm. If necessary use a large, strong board or similar support for the vehicle jack.
• Only change the wheel yourself if you feel confident carrying out the procedure. If not, seek expert assistance.
• Always use suitable and undamaged tools to change the wheel.
• Always switch off the engine, apply the handbrake and move the selector lever to the position P or select a gear on a manual gear-box in order to reduce the risk of unintended vehicle movement.
• The wheel bolt tightening torque should be checked with a torque wrench immediately after changing a wheel. 3. With a DSG® dual clutch gearbox, move the selector lever to position P =>page 260.
4. Stop the engine and remove the key from the ignition =>page 257.
5. Manual gearbox: select a gear =>page 260.
6. Make sure all vehicle occupants exit the ve-hicle and move to safety, for instance be-hind the safety barrier.
7. Chock the wheel diagonally opposite the wheel being worked on with a stone or a similar object. ""

Practical tips 427

A WARNING
Changing the bulb incorrectly can cause ac-cidents and serious Injuries.
• When working In the engine compartment, always read and observe the safety warnings =>page 350. The engine compartment of any motor vehicle Is a dangerous area. Serious Injuries can be sustained here.
• Halogen 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 famili-ar with the procedure. If you are uncertain of what to do, the work should be carried out by a qualified workshop.
Indicator lamp
r--f"n First read and observe the introductory L-.J,:.lJ Information and safety warnings & on page 432.
Lit up Possible cause
A bulb in the exterior lighting has failed.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will go out after a few seconds.
A WARNING
Failure to observe illuminated warning lamps and text messages can lead to your vehicle breaking down In traffic, and can cause acci-dent and serious Injury.
• Never ignore any illuminated warning lamps or text messages.
Information on changing bulbs
r--f"n First read and observe the introductory L-.J,:.lJ Information and safety warnings & on page 432.
A WARNING (Continued)
• 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 head-light housing In the engine compartment and on the tall light cluster housing. Protect your hands when changing bulbs.
CD
Damage to the electrical system can be caused by water entering the system if the rubber cov-ers or plastic caps on the headlight housing are not properly mounted after a bulb has been changed.
If bulbs of the exterior lighting fail, an indicator lamp lights up in the instrument cluster.
Solution
Change the defective bulb.
A WARNING (Continued)
• Stop the vehicle as soon as possible and when safe to do so.
CD
Failure to observe Illuminated indicator lamps and text messages can lead to your vehicle be-ing damaged.
m if an individual light emitting diode (LED) in W the exterior lighting fails, no warning is given. If all LEDs fail, this is indicated by the indicator lamp*··
Checklist
Always carry out the following actions for changing a bulb in the given order => &:
1. Park the vehicle on a firm and level surface at a safe distance from the flow of traffic.
2. Apply the handbrake firmly =>page 269. .,..
