Things to remember when driving114The risk of hydroplaning increases with declin-ing tread depth on the tire s, refer also to Mini-mum tread depth on page 198.Driving through waterDrive though calm water only if it is not deeper than 1 ft/25 cm and at this height no faster than walking speed, up to 6 mph/10 km/h. Otherwise, the vehicle's engine, the electrical systems and the transmission may be damaged.<Use the parking brake on inclinesOn inclines, do not hold the vehicle for a lengthy period using the clutch; use the parking brake instead. Otherwise, greater clutch wear will result. <For more information about the drive-off assis-tant, refer to page 80.Braking safelyYour BMW is equipped with ABS as a standard feature. Applying the brakes fully is the most effective way of braking in situations in which this is necessary. Since the vehicle maintains steering responsiveness, you can still avoid possible obstacles with a minimum of steering effort.Pulsation of the brake pedal, combined with sounds from the hydraulic circuits, indicate that ABS is in its active mode.Driving in wet conditionsWhen roads are wet or there is heavy rain, briefly exert gentle pre ssure on the brake pedal every few miles. Monitor traffic conditions to ensure that this maneuver does not endanger other road users. The heat generated in this process helps dry the pads and rotors. Full braking efficiency will th en be available when you need it.HillsTo prevent overheating and the resulting reduced efficiency of the brake system, drive long or steep downhill gradients in the gear in which the least br aking is required. Even light but consistent brak e pressure can lead to high temperatures, brake wear and possibly even brake failure.<You can increase the engine's braking effect by shifting down, all the way to first gear if neces-sary. This strategy helps you avoid placing excessive loads on the brake system. Down-shifting in manual mode of the automatic trans-mission, refer to page 54.7-gear sport automatic transmission with dual clutch: Never drive with the trans-mission in neutral or with the engine switched off; otherwise, engine braking action will not be present or there will be no power assistance to the brakes or steering.Manual transmission: Never drive with the clutch held down, with the transmission in neu-tral or with the engine switched off; otherwise, engine braking action will not be present or there will be no power a ssistance to the brakes or steering. Never allow floor mats, carpets or any other objects to protrude into the area around the pedals; otherwise, pedal function could be impaired.<Corrosion on brake rotorsWhen the vehicle is driv en only occasionally, during extended periods when the vehicle is not used at all, and in op erating conditions where brake applications are less frequent, there is an increased tendency for corrosion to form on rotors, while contaminan ts accumulate on the brake pads. This occurs because the minimum pressure which must be exerted by the pads during brake applications to clean the rotors is not reached.Should corrosion form on the brake rotors, the brakes will tend to re spond with a pulsating effect that even extend ed application will fail to cure.When the vehicle is parkedCondensation forms wh ile the automatic cli-mate control is in operation, and then exits under the vehicle. Traces of condensed water under the vehicle are therefore normal.
