Observe the following trolley-jack-related instructions:
1. Only trolley jacks sold or approved by BMW, with a rubber plate on their mounting, may be used!
2. Trolley jacks must be regularly serviced and always checked for functional reliability before they are used!
3. Check the rubber plate on the trolley jack prior to each use, replacing if necessary.
IMPORTANT: All-wheel drive vehicles may only be raised with the stiffening plate fitted on the front axle! Raising directly on the front axle support without stiffening plate is not permissible!
WARNING: The vehicle may be raised with a trolley jack only at the following mounting point!
NOTE: It is not permitted to raise the vehicle at the rear differential cover!
Risk of damage! Jacking point (1) must be present! Align the rubber plate on the trolley jack to the jacking point (1) in such a way that there is no contact to adjacent components and that they are therefore not damaged.
