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.

Observe any legal requirements when towing.
For technical reasons, vehicles with a dis-charged battery must not be tow-started.
Towing a vehicle when the engine is switched off and the ignition is switched on discharges the vehi-cle battery. Depending on the vehicle battery charge level, the drop in voltage can be large enough after just a few minutes that electrical con-sumers in the vehicle will no longer function, e.g. the hazard warning lights.
Additional information and warnings:
• Exterior views =>page 5
• Changing gear =>page 257
• Engine management system and exhaust puri-fication system =>page 407
• Jump starting =>page 443
A wARNING
Never tow a vehicle that has no power sup-ply.
• Never remove the key from the ignition. The steering lock may be activated and you will no longer be able to steer the vehicle. This can lead to a loss of control of the vehi-cle, accidents and serious injuries.
Notes on tow-starting
t""""("'n First read and observe the introductory L-.lc:.JJ information and safety warnings & on page 446.
Vehicles should not be tow-started wherever possible. Use jump leads to start the engine in· stead =>page 443.
For technical reasons, the following vehicles can-not be tow-started:
4461 If and when
A WARNING (Continued)
• If the power supply to the towed vehicle is disconnected, stop towing immediately and seek expert assistance.
A WARNING
If a vehicle is being towed, the vehicle han-dling and braking effect will change signifi-cantly. Please note the following in order to reduce the risk of an accident or serious inju-ries:
• Notes for the driver of the towed vehicle:
-You will need to depress the brake ped-al more vigorously than normal as the brake servo is not working. Always be careful not to drive Into the vehicle that is pulling your vehicle.
-You will need to turn the steering wheel more vigorously as the power-assisted steering function Is not working.
• Notes for the driver of the towing vehicle
-Accelerate carefully and gently.
-Avoid sudden braking and driving ma· noeuvres.
-Brake earlier than normal by pressing lightly on the brake pedal.
CD
• Remove and install the cover and the tow-ing eye carefully so as to avoid damage to the vehicle, e.g. the palntwork.
• Unburnt fuel can enter the catalytic convert· er and damage it while the vehicle Is being tow-ed.
• If the vehicle battery has discharged, the en-gine control units will not function properly.
However, if the vehicle still has to be tow-started (manual gearbox):
• Engage second or third gear.
• Keep the clutch pressed down.
• 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.
Notes on towing
i"""fl1 First read and observe the introductory L-W! information and safety warnings & on page 446.
Fixed towing eye at rear
On vehicles without a towing bracket there is a fixed towing eye under the bumper at the rear right.
Towing bracket instead of a fixed towing eye
If the vehicle has a factory-fitted towing bracket, it should also be used for towing other vehicles.
Tow rope or tow bar
lt 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. lt 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.
Vehicles with a factory-fitted towing bracket must be towed only with a tow bar that is specially designed for fitting to a ball coupling 139.
When your vehicle has to be towed:
• Switch on the ignition.
• Select the neutral position or move the selector lever to N 257.
• Release the handbrake. if necessary.
CD
When tow-starting, unburnt fuel can enter the catalytic converter and damage it. <1
• Do not allow the vehicle to be towed at speeds faster than 50 km/h (30 mph).
• Do not allow the vehicle to be towed further than 50 km.
• Vehicles with a DSG® dual clutch gearbox may only be towed by the breakdown truck with the front wheels raised.
Towing vehicles with four-wheel drive (4MOTION)
Vehicles with four-wheel drive (4MOTION) may be towed with a tow bar or tow rope. If the vehicle is towed with the rear or front axle raised, the engine must be switched off otherwise the drive train could be damaged.
When should your vehicle not be towed?
• If, due to damage, the vehicle gearbox no lon-ger contains any lubricant.
• If the vehicle battery is discharged.
• If the distance to be towed is further than 50 km -applies only to vehicles with the DSG® dual clutch gearbox.
• If the steering function or the operating clear-ance of the wheels cannot be ensured, e.g. after an accident.
Please comply with the following when towing another vehicle:
• Comply with legal regulations.
• Comply with the information on towing con-tained in the owner's manual for the other vehicle. <1
