Giving and receiving assistance Rear The tow fittings used should be on the same side on both vehicles. Should it prove impossible to avoid mounting the tow bar at an offset angle, please note the following: > Clearance and maneuvering capability will be strictly limited during cornering. > When mounted at an angle, the tow bar will exert lateral forces, tending to push the vehicle sideways. Being towed Make sure that the ignition is switched on, refer to page 50; otherwise, the low-beam headlights, tail lights, turn signals and windshield wipers would not be available. If the vehicle electrical system fails, do not tow-start or tow the vehicle. The electric steering-wheel lock cannot be unlocked and the vehicle cannot be steered. For information on jump starting, refer to page 192. There is no power assistance with the engine stopped. This then requires increased effort for braking and steering.< Switch on the hazard warning flashers depending on the local regulations. If the electrical system fails, mark the vehicle to be towed, e.g. with a sign or warning triangle in the rear window. Engage selector lever position N with the ignition switched on. Attach the tow bar to the tow fittings only, as attachment to other vehicle parts can lead to damage.< With tow rope When starting off in the towing vehicle, make sure that the tow rope is taut. To avoid jerking and the associated stresses on vehicle components when towing, always use nylon ropes or nylon straps. Attach tow ropes to the tow fittings only, as attachment to other vehicle parts can lead to damage.< With tow truck Towing methods Do not lift vehicle by tow fitting or body and chassis parts; otherwise, damage may result.< In some countries, towing with tow bars or ropes in public traffic is not permitted. Familiarize yourself with the regulations on towing in the respective country. Have the BMW transported with a tow truck with a so-called lift bar or on a flat bed. Tow-starting Do not tow-start the vehicle if possible, but instead start the engine by means of jump starting, refer to page 192. With a catalytic converter, the vehicle should only be tow-started with the engine cold. If the electrical system fails, do not towstart or tow the vehicle, as otherwise the electric steering-wheel lock cannot be unlocked and the vehicle cannot be steered.< With tow bar The towing vehicle may not be lighter than the vehicle to be towed; otherwise, it will not be possible to reliably control vehicle response.< 194 Online Edition for Part No. 01 41 0 012 118 - © 02/06 BMW AG
