Tire treadTread depth should not be allowed to
go below 1/8 in/3 mm, even though
European legislation, for example,
requires a mimimum tread depth of only
1/16 in/1.6 mm. Below 1/8 in/3 mm
tread depth, there is a great risk of
hydroplaning, even at relatively moder-
ate speeds and with only small amounts
of water on the road.
At tread depths below approx.
3/16 in/4 mm, tire performance under
winter driving conditions deteriorates
noticeably. Worn tires should therefore
be replaced for safety considerations.
Tread wear indicators in the tread-
groove base, see arrow, are distributed
around the wheel circumference and
are labeled on the tire sidewall with
TWI, Tread Wear Indicator. At a tread
depth of 1/16 in/1.6 mm, the indicators
signal that the legally permissible wear
limit has been reached.
New wheels and tires
Have new wheels and tires
mounted only by a BMW center or
specialized tire shop that works
according to BMW requirements with
appropriately trained personnel. Work
that is improperly carried out could
result in consequential damage and
pose safety hazards.<
Ask your BMW center for details con-
cerning the correct wheel and tire com-
bination. Have the wheels balanced
each time a wheel or tire has been
replaced.
The correct wheel and tire combination
also affects different systems such as
ABS or DSC. The function of these sys-
tems is impaired if improper wheel and
tire combinations are used.
BMW advises against using
retreaded tires, as driving safety
could otherwise be impaired. The rea-
son for this are the possibly different
tire casing structures involved, some of
which may be greatly aged, factors
which can lead to a decrease in durabil-
ity.<

Brake fluidIndicator lamp
The warning lamp comes on
even though the parking brake
is released:
The brake fluid level is too low, refer to
page 18. At the same time, there may
be significantly greater pedal travel.
Have the system checked immediately.
Warning lamp for Canadian
models.
If you continue driving, extended
pedal travel may be necessary
and braking distances may be signifi-
cantly longer. Be sure to adapt your
driving style accordingly.<
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Due to loss in brake fluid, pedal travel
can lengthen and braking efficiency
may be reduced.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet for
US models or the Warranty and Service
Guide Booklet for Canadian models.
Brake fluid is toxic and damages the
vehicle's paint. You should always store
it in its closed original container and in
a location inaccessible to children.
Do not spill the brake fluid and do not
fill the brake fluid reservoir beyond the
MAX mark. The brake fluid could ignite
upon contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating
the disposal of brake fluid.<

Mobile Service*To establish contact with the BMW
Group's Mobile Service:
Press button 2 for at least 2 seconds.
The indicator lamp above the buttons
lights up. As soon as a telephone con-
nection has been set up with the Mobile
Service, the indicator lamp flashes.
Depending on the country you are in,
your vehicle's current location will also
be transmitted if your vehicle is
equipped with an activated BMW Assist
function.
Jump-startingWhen your battery is discharged, you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Use only jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal.
Carefully observe the following instruc-
tions to avoid personal injury and/or
damage to one or both vehicles. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all consumers in both
vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles, otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Be sure to connect the jumper
cables in the right order; other-
wise there is a risk of injury due to
sparks being created near the battery.<
The jump-starting terminal located in
your BMW's engine compartment
serves as the positive battery terminal;
refer also to the engine compartment
overview on page 124. The cover of this
auxiliary terminal is marked with a +.
1. Open the cover of the BMW jump-
starting terminal. Do so by pulling the
tab – see arrow 1
2. Connect one terminal clamp of the
plus/+ jumper cable to the positive
terminal of the battery or to a jump-
starting terminal in the donor vehicle
