1. Close all windows and the panorama glass sunroof. 2. Greatly increase the air supply of the air conditioning system or automatic climate control, refer to page 60 or 63. Hot exhaust system High temperatures occur in the exhaust system of every vehicle. Do not remove the heat shields installed adjacent to various sections of the exhaust system, and never apply undercoating to them. When driving, standing at idle, and parking, take care to avoid possible contact between the hot exhaust system and any highly flammable materials such as hay, leaves, grass, etc. Such contact could lead to a fire, resulting in serious personal injury and property damage.< When the vehicle is parked Condensation forms in the air conditioner system during operation, and then exits under the vehicle. Traces of condensed water under the vehicle are therefore normal. Before driving into a car wash Fold in the exterior mirrors, refer to page 30; otherwise, they could be damaged due to the width of the vehicle. Deactivate the rain sensor; otherwise, damage could result from undesired wiper activation, refer to page 40. Mobile communications devices in vehicle BMW does not recommend using mobile communications devices, e.g. mobile phones, on the interior of the vehicle without a direct connection to an outside antenna. Otherwise, the vehicle electronics and mobile communications device can affect each other. In addition, there is no assurance that the radiation which results during transmission will be dissipated from the vehicle interior.< 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 tires and road surface, ultimately undermining your ability to steer and brake the vehicle.< The danger of hydroplaning increases as tire tread depth decreases, also refer to Minimum tread depth on page 89. Interior and exterior mirror, automatically dimming* Driving through water Do not drive through water on the road if it is deeper than 20 in/50 cm, and then only at walking speed. Otherwise, the vehicle's engine, the electrical system, and the transmission may be damaged.< Using handbrake on inclines Two photocells are used to control the automatically dimming interior and exterior mirrors. One is integrated into the mirror glass, the other is located on the back of the mirror. Do not hold the vehicle in place on slopes by slipping or riding the clutch, use the handbrake instead. Otherwise, greater clutch wear will result.< Reference 77 Online Edition for Part No. 01 41 0 012 213 - © 02/06 BMW AG Mobility Driving tips Controls At a glance 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 any kind of sticker to the windshield in front of the mirror, either.
