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. Instead, you can also add 1 liter of ATF oil to the box. Reason: When the engine is off, the oil pump of the box does not work. Therefore, 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!
