Detaching Information on tires / rims AH40.10-P-9411-01MCU 1 Unscrew valve protective cap (3) from valve (1) and unscrew valve element from the valve (1) 2 Remove wheel balance weights 3 Position bead breaker shovel of tire mounting device on the tire bead 4 Pry off the tire on the inside and outside over the safety hump of the disc wheel. 5 Clamp disc wheel on the tire mounting device 6 Align mounting head at a small distance (X, Y) to the disk wheel and fix in position 7 Position disk wheel so that valve (1) is approx. 10 cm in front of mounting head looking in the direction of rotation 8 Using an assembly lever, lever the tire bead over the assembly lug of the tire mounting device and pull off tire 9 Checking condition of rim If damaged, replace disk wheel. 10 Unscrew nut (2) on valve (1) and remove wheel sensor (A69/1, A69/2, A69/3, A69/4) downwards 11 Remove seal ring (4) and sleeve (5) and pull valve (1) out of the wheel sensor (A69/1, A69/2, A69/3, A69/4) Attaching 12 Position valve (1) on wheel sensor (A69/1, A69/2, A69/3, A69/4) and slide sleeve (5) as well as seal ring (4) onto the valve (1) Installation: The marking (arrow A) on the sleeve (5) must be opposite the marking (arrow B) on the wheel sensor (A69/1, A69/2, A69/3, A69/4). The valve (1), sleeve (5), seal ring (4) and nut (2) are available in a repair kit and should always be replaced. 13 Position wheel sensor (A69/1, A69/2, A69/3, A69/4) with valve (1) on the disk wheel and tighten nut (2) *BA40.10-P-1002-01E 14 Coat inner and outer rim flange as well as both tire beads using tire assembly paste. Align mounting head of the tire mounting device at a small distance (X, Y) to the disk wheel Only use tire mounting paste for mounting tires. 15 Position the disk wheel so that the valve (1), viewed in the direction of rotation, is located approx. 180° degrees in front of the mounting head 16 Put the tire on the disk wheel at an angle and pull on over the rim flange Ensure that the tire does not exert any pressure on the wheel sensor (A69/1, A69/2, A69/3, A69/4) during pulling on as the latter can be damaged as a result. Observe the running direction on tires with specified running direction. Put as little stress as possible on bead area. 17 Align match points of the tire and disk wheel with each other, remove disk wheel with tire from tire mounting device 18 Pump up tire without valve element to a maximum of 3 bar The tire must slide evenly over the safety hump of the disk wheel, if necessary coat the tire bead with tire assembly paste again. 19 Screw the valve element into the valve (1) and correct tire inflation pressure to the specified value In order to prevent electrochemical corrosion, only special nickel-plated valve elements may be used may be used in the aluminum valves of wheel sensors (A69/1, A69/2, A69/3, A69/4). Uncoated brass inserts (standard valve elements) lead to severe corrosion damage and can destroy the valve. See tire pressure information on the B-pillar of the driver door. 20 Balance wheel AR40.10-P-1040MCC

Remove/install Risk of death caused by vehicle slipping or toppling off of the lifting platform. Align vehicle between columns of vehicle lift and position four support plates at vehicle lift support points specified by vehicle manufacturer. AS00.00-Z-0010-01A 1 Raise vehicle with vehicle lift 2 Secure vehicle on vehicle lift When work is continued on the vehicle such as, e.g. when supporting major assemblies using a jack (e.g. transmission jack) which exert an uneven load distribution, as well as when removing the following components: Front axle, front axle carrier, axle tube, rear-axle frame-type integral support, engine or transmission. AR00.60-P-0100MCC 3 Detach wheel cover Only on vehicles with steel wheels. 4 Unscrew wheel bolts and remove wheels In order to prevent damage, an impact wrench must not be used on light alloy rims. If the adapter for loosening the wheel antitheft locks is not available the set of master keys should be used. *BA40.10-P-1001-01E see scheme 11 see scheme 12 5 Check wheel contact surfaces for dirt and corrosion Clean corroded surfaces with a wire brush or an emery cloth. 6 Install in the reverse order 7 Correct the tire inflation pressure in all wheels In the event of tire pressure loss: Determine cause and replace tires if necessary. 8 Press the TPM switch (S6/1s9) in the cockpit switch group (S6/1) and as a result recalibrate the tire pressure monitoring system
