Towing:
- The maximum speed is 50 km/h!
- Maximum range - 50 km!
Note: On 520i/525i models from May 1990. (with four-valve engine M50) a new 5-speed THM-R1 transmission is installed, these vehicles can be towed for a maximum of 150 km with a maximum speed of 70 km/h.
If it is necessary to tow over long distances, the rear of the vehicle must be raised, or the propeller shaft must be disconnected from the rear axle gearbox. When the engine is off, the automatic transmission pump does not work, so at high speeds and for a long time, the box will not have sufficient lubrication.
To prevent the steering wheel from locking up and you can use the direction indicators, the horn and, if necessary, the wiper, turn on the ignition.
Since the hydraulic brake booster only works when the engine is running, the brake pedal must be pressed harder when the engine is not running!
