nection to an outside antenna. Otherwise, the
vehicle electronics and mobile communication
device can influence one another. In addition,
there is no assurance that the radiation which
results from transmission will be dissipated
from the vehicle interior.<
Interior and exterior mirrors, automatic
dimming feature*
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.
Hydroplaning
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 completely lose contact
with the road surface, so that neither 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 page195.
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 handbrake on inclines
On inclines, do not hold the vehicle with
the clutch; use the handbrake. Otherwise
greater clutch wear will result.<
Sequential manual gearbox SMG
On uphill slopes, drive off without delay.
Do not hold the vehicle in place by
depressing the accelerator pedal; apply the
handbrake instead. Otherwise, the transmis-
sion could overheat.<
Also use the drive-off assistant, refer to
page87.
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.<

Replacing components
Onboard tool kit
The onboard tool kit is stored in a compartment
on the right-hand side of the luggage compart-
ment. Remove the cover.
Wiper blades
1.Fold up the wiper arm.
2.Remove the cover. To do so, press the hook
on the bottom, see arrow.
3.Fold the wiper blade upwards.
4.Remove the wiper blade in the direction of
the windshield, see arrow.In order to avoid damage, make sure that
the wiper arms are against the windshield
before you open the engine compartment.<
Lamps and bulbs
Lamps and bulbs make an essential contribu-
tion to vehicle safety. They should, therefore,
be handled carefully. BMW recommends hav-
ing your BMW Center perform any work that
you do not feel competent to perform yourself
or that is not described here.
Never touch the glass of new bulbs with
your bare fingers, as even minute
amounts of contamination will burn into the
bulb's surface and reduce its service life. Use a
clean tissue, cloth or something similar, or hold
the bulb by its base.<
You can obtain a selection of replacement bulbs
at your BMW Center.
When working on electrical systems,
always begin by switching off the con-
sumer in question, otherwise short-circuits
could result. To avoid possible injury or equip-
ment damage when replacing bulbs, observe
any instructions provided by the bulb manufac-
turer.<
For care and maintenance of the headlamps,
please follow the instructions in the separate
Caring for your vehicle brochure.
If the routine for changing a particular
bulb is not described here, please contact
your BMW Center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel.<
