Things to remember when driving

112

The risk of hydroplaning increases with declin-

ing tread depth on the tires, refer also to Mini-

mum tread depth on page 194.

Driving through water

Drive 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 inclines

On 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 safely

Your 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 conditions

When roads are wet or there is heavy rain,

briefly exert gentle pressure 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 then be available when

you need it.

Hills

To prevent overheating and the resulting

reduced efficiency of the brake system,

drive long or steep downhill gradients in the

gear in which the least braking is required. Even

light but consistent brake 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 assistance 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 rotors

When the vehicle is driven only occasionally,

during extended periods when the vehicle is not

used at all, and in operating conditions where

brake applications are less frequent, there is an

increased tendency for corrosion to form on

rotors, while contaminants 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 respond with a pulsating

effect that even extended application will fail

to cure.

When the vehicle is parked

Condensation forms while the automatic cli-

mate control is in operation, and then exits

under the vehicle. Traces of condensed water

under the vehicle are therefore normal.
