Mobile communications devices in vehicle BMW discourages the use of mobile communications devices, e.g. mobile phones, inside the vehicle without a direct connection to an outside antenna. Otherwise, the vehicle electronics and mobile communication device can influence one another. In addition, there is no assurance that the radiation which results from transmission will be dissipated from the vehicle interior.< Driving through water Do not drive through water on the road if it is deeper than 1 ft/30 cm, and then only at walking speed at the most. Otherwise, the vehicle's engine, the electrical systems and the transmission may be damaged.< Starting off On slopes The starting assistant enables starting off on slopes virtually without rolling back. 1.

Driving tips Interior and exterior mirrors, automatic dimming feature* This feature is controlled by two photocells in the inside rearview mirror. One is integrated into the glass of the mirror, while the other is located at an offset position on the rear of the mirror housing. For trouble-free operation, keep the photocells clean and do not cover the area between the interior rearview mirror and the windshield. Do not attach stickers of any kind to the windshield in front of the mirror, either. Hydroplaning When driving on wet or slushy roads, reduce road speed. If you do not, a wedge of water can form between tires and road surface. This phenomenon is referred to as hydroplaning, and is characterized by a partial or complete loss of contact between the tires and the road surface, ultimately undermining your ability to steer and brake the vehicle.< On a slippery surface 1.
