Caring for your carThe buildup of an electrostatic charge
on the seat covers, particularly if atmo-
spheric humidity is low, can give the
occupants an unpleasant electric shock
if they touch metal body parts after leav-
ing the vehicle. Although this not dan-
gerous in any way, it can be avoided by
touching a bare or polished metal part
of the car while getting out.
Leather care The leather upholstery
* used by BMW
is a natural product of the highest qual-
ity, processed using state-of-the-art
methods to ensure that it will maintain
its high quality for years to come, pro-
vided that it is properly cared for.
Because this product is manufactured
using natural materials, you must make
allowance for its special characteristics
and for the peculiarities of its use and
care.
Regular periodic cleaning and care are
essential, as dust and road dirt act as
abrasives in the pores and creases of
the material. This leads to wear spots
and premature brittleness on the sur-
face of the leather. We therefore sug-
gest that you clean the leather with a
vacuum cleaner or dust cloth at fre-
quent intervals.
For cleaning use BMW leather cleaning
foam.Since dirt and grease gradually attack
the protective layer of the leather, the
cleaned surfaces should be treated with
BMW leather care agent. This also acts
as an antistatic agent.
To protect against moisture and water
treat the leather with BMW Impregnat-
ing Agent.
We recommend that you perform this
procedure twice a year on leather ex-
posed to normal use.
Spills should be wiped up immediately.
Remove grease and oil stains without
rubbing, but rather by dabbing with
spot remover.
If the upholstery is to be exposed to in-
tense sunlight or if the vehicle is to be
stored for an extended period, cover all
leather surfaces (or, better yet, the win-
dows) to prevent fading.
A full range of car-care products is
available from your BMW center.<

Located next to the jack.
Loosen the wing nut (arrow) by hand,
remove the storage tray and take out
the spare wheel
>Lug wrench – is in the onboard tool
kit on the underside of the luggage
compartment lid (refer to page 140).460de059
Procedure1 Please observe the safety precaus-
tions stated on the previous page
2 Secure the vehicle against rolling:
Place the wedge against the rear
surface of the front tire on the side
opposite the side being raised. If
the vehicle is parked on a down-
ward slope, place the wedge se-
curely in front of the tire. If the
wheel must be changed on a sur-
face with a more severe slope, take
additional precautions to secure the
vehicle from rolling
3 Wheels with full wheel covers:
Reach into the ventilation openings
and pull the cover off462de251
4 Loosen the lug bolts 1/2 turn
5 Place the jack under the jacking
point nearest the wheel you are
changing (refer to the illustration at
the left) in such a way that the base
of the jack is positioned vertically
under the jacking point relative to
the entire surface, and that the jack
head fits securely into the square
recess of the jacking point (refer to
illustration detail) when the jack is
cranked
6 Crank the car up until the wheel in
question is raised from the ground
7 Unscrew the lug bolts and remove
the wheel
8 Remove accumulations of mud or
dirt from the mounting surfaces of
the wheel and hub; clean the lug
bolts462de252

150n
Changing tires9 Position the new wheel or the
space-saver spare tire
* on the hub
and screw at least two lug bolts
finger-tight into opposite bolt holes
10 Screw in the remaining lug bolts.
Tighten all the bolts securely
11 Lower the jack and remove it from
beneath the car
12 Tighten the lug bolts, alternating
between bolts positioned opposite
one another
462de266
13 If your wheels are equipped with full
wheel covers
*: Position the wheel
cover with the valve opening over
the valve (arrow) and press it onto
the wheel with both hands
14 Inflate tire to the proper pressure as
soon as possible.
For vehicles with RDC Tire Pressure
Control
*:
Reactivate the system after mount-
ing either the spare tire or after in-
flating tire to proper pressure.
(Refer to page 82).
Only use original BMW full wheel
covers, otherwise, the trim piece
may not fit securely. The full wheel
cover may not be installed on the
space-saver spare tire
*, since this
could damage the cover.<
462de279
The vehicle jack is designed for
changing tires only. Never use it to
raise another vehicle model or any load
of any kind, as this could lead to acci-
dents and personal injury.
Have the lug bolts checked for proper
tightness with a calibrated torque
wrench at the earliest possibility [torque
specification: 72 lb.ft. (100 Nm)].<
When storing the wheel, take care to
ensure that you do not damage the re-
taining pin in the spare tire recess.
If light-alloy wheels other than Original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as quickly as
possible and have the new wheel bal-
anced.
For black-painted aluminum wheels
*,
use only those balancing weights ap-
proved by BMW for use with light alloy
wheels. Never attempt to balance these
wheels using standard balance weights.

Battery
A highly-explosive gas is gener-
ated when the battery is
charged.
If you happen to get acid in your
eyes, rinse thoroughly for 15 min-
utes with clear water. Consult a
physician immediately. Rinse your skin
or clothing with plenty of water if you get
acid spray on them. If electrolyte is acci-
dentally ingested, consult a physician
immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
Battery careThe battery is completely maintenance-
free, as per DIN 43 539/2; that is, the
amount of acid put in the battery origi-
nally will normally last for the service life
of the battery.
Charge conditionWith the help of the "Magic Eye", a
hydrometer, you can read the battery's
charge state:
>Green: Adequate charge.
>Black: Not adequately charged. The
battery must be recharged. Please
contact your authorized BMW center
for additional information.
>Yellow: Replace the battery.
The service life specified for the
battery can be achieved only if it is
always kept adequately charged. If the
vehicle is primarily used for stop-and-
go traffic, be sure to check the charge
state often.<460de252
Removal and installation
Do not disconnect the battery
cables when the engine is run-
ning, otherwise the ensuing voltage
surge will damage the vehicle's on-
board electronics.
Do not alter the positive terminal wiring
in any way, otherwise the safety battery
terminal's safety function will no longer
be guaranteed. Repair and disposal are
to be performed exclusively by trained
technicians.<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and
that the retaining bracket is installed
with the center adjustment screw. If this
is not done, the battery will not be ade-
quately secured in case of an acci-
dent.<

Battery FusesCharging the battery Charge the battery in the vehicle only
when the engine is not running.
Before doing any work on the
electrical system, be sure to
unclamp the cable from the battery's
negative terminal, or it could cause
short-circuiting, a fire or personal
injury.<
If the vehicle is to be parked longer than
4 weeks, disconnect the battery from
the vehicle's electrical system by dis-
connecting the negative terminal cable.
If you intend to store your car for longer
than six weeks: Remove the battery,
charge it and store it in a cool (but frost-
free) room. Recharge the battery every
6 months at the latest, at the very least
before each installation, or else it will be
unusable. Every time the battery is dis-
charged, especially over extended peri-
ods, its service life is reduced.
Return used batteries to a recy-
cling point or your authorized
BMW center. Maintain the battery in an
upright position for transport and stor-
age. Secure the battery against tilting in
transit.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
Therefore, make sure that the brake
fluid is changed every two years at the
latest, regardless of the display. Com-
ply with the information provided on
page 127.<
If an electrical accessory should fail,
switch it off and check the fuse. In glove compartment1 Open the glove compartment and
turn the two white quick-release
fasteners outward. Spare fuses and
plastic tweezers are located on the
fuse holder
2 Use the plastic tweezers to remove
the fuse for the accessory or equip-
ment that has stopped working
3 If the fuse is burned through (the
metal strip is melted and separated),
replace it with a new fuse of the same
ampere rating (color code).460de062

154n
Fuses Microfilter The fuses, their respective ampere rat-
ings and the equipment in their circuits
are all indicated below the fuse holder.
To close the fuse holder, snap it into
position at the top and turn the two fas-
teners inward.
Do not attempt to repair a burned
fuse or replace it with a fuse hav-
ing a different color or amperage rating.
To do this could cause a fire in the vehi-
cle resulting from a circuit overload.<
If a fuse blows repeatedly, refer the
problem to your authorized BMW center
for repair.
