Word-matching principle
The system's word-matching principle makes it
easier for you to enter the names of towns or
streets. The system runs ongoing checks, com-
paring your destination entries with the data
stored in the vehicle as the basis for instant
response. The benefits for you include:
>Names of towns entered may differ from the
official versions if you are using a spelling
that is customary in another country.
Example:
Instead of the German spelling "München"
you can also enter the English spelling
"Munich" or the Italian spelling "Monaco".
>When you are entering the names of towns
and streets the system will complete them
automatically as soon as enough letters are
available to ensure unambiguous identifi-
cation.
>The system offers only those letters for
selection of name entries that are stored in
the vehicle. Thus, entry of erroneous or
unregistered names is impossible.

What to do if…
What to do if…
>The current position cannot be displayed?
The position is in an unrecognized region, in
a poor reception area, or the system is in the
process of determining the position.
Reception is generally available when you
are in the open.
>Destination guidance does not accept an
address without the street name?
A downtown area cannot be determined for
the town or city that has been entered. Input
any street in the selected town/city and
start destination guidance.
>The destination guidance does not accept a
destination?
The destination data are not contained in
the navigation data. Choose a destination
as close as possible to the original one.
>The letters for a destination cannot be
selected during destination entry?
The stored data do not contain the data of
the destination. Select a destination that is
as close as possible to the original.
>The map view is displayed in black and
white?
When the traffic bulletin map is activated,
the Control Display changes to a black and
white display. This enables a better view of
the traffic bulletins.
>Voice instructions are no longer issued
before intersections during destination
guidance?
The area has not yet been fully recorded, or
you have left the recommended route and
the system requires a few seconds to calcu-
late a new route suggestion.

Inserting mobile phone
1.If applicable, remove the protective cap
from the mobile phone's antenna connector
so that the mobile phone can engage in the
snap-in adapter.
2.With its buttons facing upward, slide the
mobile phone up towards the electrical con-
tact points and press it downward until it
engages.
The mobile phone's battery is charged as soon
as the vehicle is in radio readiness or the steer-
ing is unlocked.
To conserve vehicle battery power, you
should avoid using the mobile phone
when the ignition is switched off.<
Removing mobile phone
Press the button.

Wheels and tires
198
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page199.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Designation for specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 1/8 in/
3mm, although, for example, European legisla-
tion only specifies a minimum tread depth of 1/16 in/1.6 mm. At tread depths below 1/8 in/
3 mm there is an increased risk of high-speed
hydroplaning, even when only small amounts of
water are present on the road surface.
When winter tires wear down past a tread depth
of 1/6 in/4 mm, they become perceptibly less
suitable for winter conditions. In the interest of
safety, new tires should be installed.
Wear indicators in the base of the tread groove
are distributed around the tire's circumference;
the letters TWI, for Tread Wear Indicator, on the
tire's sidewalls identify tires that incorporate
these wear indicators. Once the tire tread has
worn down to the wear indicators, the tire has
worn to a depth of 1/16 in/1.6 mm.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more sus-
ceptible to road hazard and consequential
damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW center or tire shop that works
according to BMW repair procedures with cor-
respondingly trained personnel. If necessary,
have the vehicle towed there.
Otherwise, tire damage can be extremely dan-
gerous for vehicle occupants and other road
users.<

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.
Only change bulbs while they are cool to
the touch; otherwise, you could suffer
burns.<
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 of the headlamps, please follow the
instructions in the chapter entitled "Care"'.
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.<
Light-emitting diodes LED
Light-emitting diodes installed behind translu-
cent lenses serve as the light source for many of
the controls and displays in your vehicle. These
light-emitting diodes, which operate using a
concept similar to that applied in conventional
lasers, are officially designated as Class 1 light-
emitting diodes.
Do not remove the covers or expose the
eyes directly to the unfiltered light source
for several hours; otherwise, this could cause
irritation to the retina.<

Xenon lamps
Have any work on the xenon lamp system,
including bulb replacements, performed
only by a BMW center or a workshop that works
according to BMW repair procedures with cor-
respondingly trained personnel. Otherwise, if
such work is carried out improperly, the high
voltage in the system presents the danger of
fatal injuries.<
