Increase the air supply from the air condi-

level. Refer to page

High temperatures occur with every vehi-
cle equipped with a catalytic converter. 

Heat shields are installed adjacent to some sec-
tions of the exhaust system. Never remove 
these shields; do not apply undercoating to 
their surfaces. When driving, standing at idle 
and parking the vehicle, take care to avoid con-
tact between the hot exhaust system and flam-
mable materials, e.g. hay, leaves, grass, etc. 
Such contact could lead to a fire, resulting in 
serious personal injury and property damage.

<

When driving on wet or slushy roads, 
reduce vehicle speed. If you do not, a 

wedge of water may form between the tires and 
the road surface. This phenomenon can lead to 
partial or complete loss of traction, vehicle con-
trol and braking effectiveness.

<

Do not drive through water on the road if it 
is deeper than 1 ft/30 cm, and then only at 

walking speed. Otherwise, the vehicle's engine, 
the electrical systems and the transmission 
may be damaged.

<

On inclines, keep the vehicle from rolling 
by using the parking brake rather than by 

slipping the clutch, which would lead to a high 
degree of clutch wear.

Your BMW is equipped with ABS as a standard 
feature. If you are in a situation which requires 
full braking, it is best to brake using maximum 
brake pressure: panic stop. Since the vehicle 
maintains steering responsiveness, you can still 
avoid possible obstacles with a minimum of 
steering effort.

Pulsation at the brake pedal combines with 
sounds from the hydraulic circuits to indicate to 
the driver that ABS is in its active mode.

If the roads are wet or if there is heavy rain, it is 
advisable to gently press the brakes for a brief 
moment every few miles/kilometers. Watch 
traffic conditions to ensure that this maneuver 
does not endanger other road users. The 
resulting heat dries the brake rotors and brake 
pads. Immediate braking force is then available 
if necessary.

To prevent overheating and, as a result, 
diminished braking effectiveness, drive 

down long or steep downhill grades in a gear 
which requires the least braking. Otherwise, 
even light but consistent pedal pressure can 
lead to high temperatures, brake wear and pos-
sibly even brake failure.

<

The braking power of the engine can be further 
enhanced by downshifting the automatic trans-
mission in manual mode, if necessary, into first 
gear; refer to pages

. This prevents an 

excessive load on the brakes.

Do not coast with the clutch depressed or 
with the transmission or selector lever in 

Neutral. Do not coast with the engine switched 
off. Otherwise, the engine provides no braking 
effect while the transmission is in idling posi-
tion, and there is no power-assist for braking or 
steering when the engine is off.
Floor mats, floor carpets or other objects must 
not be in the area near the brake or accelerator 
pedal, as this could impair the movement of the 
pedals.

<

Limited vehicle use, extended periods with the 
vehicle parked or in storage, and operating con-
ditions in which braking is restricted to gentle, 
low-pressure applications will all increase the 
tendency for corrosion to form on the rotors and 
contamination to accumulate on the brake 
pads. This occurs because the minimal pres-
