Attention! The standard jack is intended only for short-term lifting of the car when changing a wheel; before performing any work under the car, it must be installed on special supports!
1. Park the car on a level, horizontal surface, if possible with a hard surface.
2. Set the parking brake securely.
3. Move the AT selector lever to position "P".
4. If necessary, put up an emergency stop sign.
5. Support the wheel located diagonally from the one to be replaced with wheel chocks.
Note: When performing the procedure on a slope, place chocks under both wheels of the serviceable axle on the downhill side.
6. Prepare the necessary tool (jack, wheel wrench) and a spare tire.
7. If equipped, remove the protective cap of the wheel, then loosen the mounting bolts of the failed wheel.
8. Prepare the standard hydraulic jack for operation: assemble the three-section handle and connect it to the jack assembly hydraulic pump drive. Check the tightness of the drain plug (2) - if necessary, tighten the plug using the square key (1) at the end of the handle.

Caution! Completely unscrewing the threaded plug carries the risk of losing hydraulic fluid!
9. Place the jack head under the appropriate platform of the front or rear axle housing - make sure that the jack is positioned strictly vertically and that its heel rests on the ground with its entire surface - if the ground is loose, place a suitable pad under the heel (in winter it is useful to have a piece of wide board in the car).
Attention! Remember that regardless of the slope, the jack must always be in a strictly vertical position!
10. Using the hydraulic pump drive handle, lift the vehicle with a jack - the damaged wheel should be completely off the ground.
11. Remove the wheel bolts and replace the wheel.
12. Check the inflation pressure of the installed spare tire and make the appropriate adjustments if necessary (see Specifications).

Note: The maximum continuous operation time of the electric tire inflator is 8 minutes.
13. Loosen the threaded plug of the jack drain hole and completely sink the piston of the latter into the cylinder.
14. Place the removed wheel and tool in their proper places.
15. Finally, tighten the wheel bolts evenly in a diagonal pattern to the required torque (130 Nm).
Attention! Only original bolts with the Mercedes-Benz logo must be used to fasten the wheels!
