Caring for your carWaxing your car Protect the finish using carnauba or
synthetic-based waxes only.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the sur-
face.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use cleaning and car-care
products that you can obtain at
your BMW center.<
Paint damageYou can touch up small areas of paint
damage with a BMW spray paint or a
BMW touchup stick.
The paint color code for your car is pro-
vided on a sticker located next to the
type plate and on the first page of your
Service and Warranty Information
Booklet (US models) or Warranty and
Service Guide Booklet (Canadian mod-
els).
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from form-
ing.
If corrosion has started to form in an
area with paint damage, remove all rust
and clean the area. Then prime the area
with a BMW Primer Stick. Finally, apply
the finish coat. Wait a few days, then
polish the repaired area. Finish by
applying a wax preservative.
More extensive paint damage should
be professionally repaired in accor-
dance with the manufacturer's instruc-
tions. Your BMW center uses original
BMW finish materials in accordance
with official repair procedures.
Caring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially dur-
ing the winter months. However, do not
use aggressive products containing
acids, strong alkalis or abrasives. Do
not use steam cleaners operating at
temperatures above 140 7 (60 6).
Follow the manufacturer's instructions.
If your vehicle has chrome parts
* such
as the window frames and door handles,
clean these parts carefully with ample
clean water and a shampoo supplement
if desired, especially if they have an
accumulation of road salt. Use chrome
polish as an additional treatment.
You can use window and glass cleaner
to clean inside window surfaces and
mirrors without smearing and streaking.
Never use polishing pastes or abrasive
(quartz) cleansers on mirror lenses.

Important safety notices
Don't remove the airbag restraint
system's gas generator. Testing
and servicing must be performed by
trained technicians only. In the event of
a malfunction, deactivation, or triggered
actuation (as a response to an accident)
of the airbag restraint system, consult
your BMW center for repairs or service
operations.
460de140
Do not modify or tamper with either the
wiring or the individual components in
the airbag system. These include the
padded steering wheel hub, the instru-
ment panel, the side trim panels of the
front or rear doors and the roof pillars or
the sides of the headliner. Do not apply
adhesive materials to these compo-
nents or cover or modify them in any
way. Do not attempt to remove or dis-
mantle the steering wheel.
To ensure compliance with official
safety regulations, have an BMW center
dispose of airbag generators.
Unprofessional attempts to service the
system could lead to failure in an emer-
gency or undesired airbag activation,
either of which could result in personal
injury. special procedures if you intend to
store the vehicle for more than three
months.

OBD interface socket The OBD interface socket for onboard
diagnostics is located on the driver's
side at the left-hand bottom of the in-
strument panel and under a cover. The
cover has the letters "OBD" on it.
The purpose of the OBD system is to
assure proper emission control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.460us250
An illuminated indicator informs you of
the need for service, not that you need
to stop the vehicle. Your system should
be checked, however, at the earliest
possible opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact your near-
est BMW center immediately. Severe
engine misfire over even a short period
of time can seriously damage emission
control components, especially the cat-
alytic converter.
If the fuel filler cap is not on tight
enough, the OBD system can detect
leaking vapor and the indicator will light
up. If the fuel filler cap is then tightened,
the indicator will usually go out after a
short period of time.

The lamps and bulbs are essential fac-
tors contributing to the safety of your
vehicle. For this reason, follow the in-
structions below carefully when replac-
ing a bulb.If you are not familiar with
any of the procedures, consult your
BMW center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Whenever working on the electri-
cal system, switch off the electri-
cal accessory you are working on or
disconnect the cable from the negative
terminal of the battery. Failure to do this
could result in short circuits.
To prevent injuries and damage, com-
ply with any instructions provided by
the bulb manufacturer.<

2 Remove and replace the bulb.460de130
When cleaning the headlamps,
please observe the following:
>Do not clean by wiping with a dry
cloth (this causes scratches). Never
use abrasives or strong solvents to
clean the covers.
>Remove dirt and contamination (such
as insects) by soaking with BMW Car
Shampoo and then rinsing with plenty
of water.
>Always use a deicer spray to remove
accumulated ice and snow Ð never
use a scraper.<
Xenon lamps
*
The service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the front fog lamps, provided traffic
laws in your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
lighting system should be performed
only by technicians with the appropriate
qualifications. Failure to comply with
this creates a risk of fatal injury.<

Changing a wheel Battery Driving with the space-saver
spare tire
*
Drive cautiously and do not exceed a
speed of 45 mph (80 km/h).
Be aware that vehicle handling will be
altered. Slower brake response time,
longer braking distances and changed
steering characteristics may be antici-
pated when approaching limit condi-
tions.
The changes in handling characteristics
will be even more pronounced in con-
junction with winter tires.
Only one space-saver spare tire
may be mounted at one time.
Mount a wheel and tire with the same
size and specifications as the others at
the earliest possible opportunity. Main-
tain correct tire pressures. Refer to
page 28.<
Battery locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 41). Use a screwdriver or a coin
to loosen the two fasteners in the illus-
tration 1/4-turn. Loosen the third fas-
tener in the upper-center side trim
panel. Remove the fasteners. In order
to remove the storage tray, slide the
side trim panel slightly upward.460de176
Charge conditionThe "Magic Eye
*" is a hydrometer that
allows you to read the charge condition
of the battery:
>Green: adequate charge.
>Black: not adequately charged. The
battery must be recharged. Please
contact your BMW center for addi-
tional 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.<

BatteryBattery careThe battery is absolutely maintenance-
free, that is, the original electrolyte will
normally last for the service life of the
battery under moderate climatic condi-
tions.
For all questions that regard the
battery, please consult your BMW
center. Since the battery is mainte-
nance-free, the following is for your
information only. your car battery. To avoid injury, please
comply with the corresponding precau-
tions whenever you work with or near
the battery.
Before handling the battery,
please read the following infor-
mation.
Wear eye protection. Do not
allow particles containing bat-
tery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Do not allow children access to
batteries and battery acid.
Never allow sparks or open
flame in the vicinity of the bat-
tery. Avoid sparks from electri-
cal cables or electrical equipment. Turn
the key to position 0 in the steering lock
when disconnecting or connecting the
battery. Do not short-circuit the battery
terminals. This creates a risk of injury
from high-energy sparks.
A highly-explosive gas is gener-
ated when the battery is charged.
If battery acid is splashed into
your eyes, rinse them thor-
oughly with clear water for at
least 15 minutes. Consult a physician
immediately. If your skin or clothing are
splashed by acid, rinse immediately
with ample clear water. If electrolyte is
accidentally swallowed, consult a phy-
sician 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.
Removal and installation
Do not disconnect the battery
when the engine is running. If you
do so, the ensuing voltage surge will
damage the vehicle's onboard electron-
ics.
Do not make any modifications in the
wires to the positive terminal. If you do
so, the protective function of the safety
battery terminal is no longer ensured.
Repair and disposal must be performed
by trained technicians only.<
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.<

154n
Battery FusesCharging the battery Charge the battery in the vehicle only
when the engine is not running.
Before doing any work on the elec-
trical system, be sure to unclamp
the cable from the battery's negative
terminal. Failure to do so can result in
short-circuits, a fire or personal injury.<
If the vehicle is to be parked longer than
four weeks, disconnect the battery from
the vehicle's electrical system by dis-
connecting the negative terminal cable
and then recharge using a suitable
charging device.
If you intend to store your car for longer
than twelve weeks: Remove the battery,
charge it and store it in a cool (but frost-
and dust-free) room. Every three months
and before reinstalling the battery, have
it recharged. If it is not recharged, it will
not be serviceable. Every time the bat-
tery is discharged, especially over ex-
tended periods, its service life is re-
duced.
Return used batteries to a recy-
cling center or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery to prevent it from tilting dur-
ing transport.<
Storage periods during which the
battery is disconnected are not
taken into consideration by the Service
Interval Display for changing the brake
fluid.
For this reason, be sure that the brake
fluid is changed every two years, re-
gardless of the information displayed.
Read and comply with the information
on page 129 covering this subject.<
If an electrical accessory should fail,
switch it off and check the fuse. In the glove compartment1 Open the glove compartment and
turn the two white quick-release fas-
teners 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
