Additional Information 

Overview Technical Data 

Prerequisite 

• Only BMW approved wheel and tire combinations are installed on the vehicle.
• Correct tread depth. The tread depth for each axle may differ from left to right by max. 1-2 mm.
• Correct tire pressure (see label on vehicle).
• All chassis and suspension components must be technically OK.
• Condition of suspension and shock absorbers OK: Visually inspect for breakage, etc.
• In vehicles with air suspension, pull fuse of air supply system so that there is no controlling down or up.

Safety Instructions 

Preprocesses 

1. Preliminary work before wheel alignment 
   • On vehicles with rear axle slip angle control: Run the "Move HSR actuator to center position" service function.
   • Drive the motor vehicle onto the axle alignment test stand so the front wheels and rear wheels are positioned in the center of the rotating/sliding plates.

   IMPORTANT:

   TECHNICAL INFORMATION

   Please observe the regulations of the various equipment manufacturers. Use only quick connectors with poly control pins (1). Due to excessive measuring inaccuracy, other quick-clamping units are not permitted!

   • Position pickups/ride height markers on the vehicle.

   • Enter customer and vehicle data.
   • Identify chassis version and select vehicle.
   • Enter tire pressure and tread depth.
   • Remove locking pins from both rotating and sliding plates.
   • Install brake tensioner.

2. Moving vehicle into normal position 
   • In vehicles with air suspension systems: run ride height adjustment with BMW diagnosis system.
   • Check vehicle interior and luggage compartment (including spare wheel well) for load status, if applicable, unload motor vehicle
   • Install the DIN vehicle load
   TECHNICAL DATA SPECIFICATION
   
   

   DIN normal position loading
   Vehicle filled up with full range of equipment for normal driving with:	On the front seats (seats in center position): 2x68 kg
   	On the rear seat (center) 1x68 kg
   	In the luggage compartment (center) 1x21 kg

3. Moving vehicle into design position 
   • Add/distribute weights around the spring struts until the vehicle ride height is within the tolerance (refer to TECHNICAL DATA ).
   TECHNICAL DATA SPECIFICATION
   
   

   Tolerance for ride height at design level
   	Tolerance for setpoint value
   	max. 2 mm
   	Difference between left and right
   	max. 2 mm

   • Measuring the vehicle ride height (A): (1) Attach the tape measure to the bottom rim flange (2) and measure the distance to the lower wheel arch edge.
