Driving through water

Drive through water on the road only if it is
not 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.

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.

tant, refer to page

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 to ensure
that 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

Sports automatic transmission with dou-
ble clutch Never drive with the transmis-

sion in neutral or the engine switched off; other-
wise, there is no engine braking action or power
assist to the brakes and steering.
Manual transmission: never drive with the
clutch depressed, the transmission in neutral,
or the engine switched off; otherwise, there is
no engine braking action or power assist to the
brakes and 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.

Cargo loading

To avoid loading the tires beyond their
approved carrying capacity, never over-

load the vehicle. Overloading can lead to over-
heating and increases the rate at which damage
