BMW 2005 330xi Sedan オーナーマニュアル

The automatic dimming feature of the interior 
and exterior mirrors

is controlled by two photo 

cells in the interior rearview mirror. One photo 
cell is in the mirror frame, see arrow; the other is 
on the back of the mirror.
In order to ensure that the system functions 
correctly, keep the photo cells clean, do not 
cover the area between the interior rearview 
mirror and windshield, and do not affix adhesive 
labels or stickers of any kind to the windshield 
directly in front of the mirror.

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

of water can form between tires and road sur-
face. This situation, known as hydroplaning, 
means that the tire can actually lose contact 
completely with the road surface, so that nei-
ther the car can be steered nor the brake be 
properly applied.

<

The risk of hydroplaning increases with declin-
ing tread depth on the tires, refer also to Mini-
mum tread depth on page

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.

<

On inclines, do not hold the vehicle with 
the clutch; use the handbrake. Otherwise 

greater clutch wear will result.

Also use the drive-off assistant, refer to

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.

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.

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 pedal 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

Never drive with the clutch pedal held 
down, with the gearshift lever or selector 

lever in neutral or with the engine switched off; 
engine braking action will not be present with
