Do not work on your vehicle
without appropriate skills. Always
switch off the engine and allow it to
cool down before working in the engine
compartment. Always disconnect the
battery before working on any electrical
systems or equipment, especially when
these are located within the engine
compartment. Comply with all applica-
ble instructions and warnings. Failure to
work in an informed, professional man-
ner when servicing components and
materials constitutes a safety hazard
for vehicle occupants and other road
users. If you are not familiar with the
guidelines, please have the operations
performed by your BMW center.<

Engine oilChecking the oil level 1 Park the vehicle on a level surface
2 Shut the engine off after it has
reached normal operating tempera-
ture
3 After approx. 5 minutes, pull the
dipstick out and wipe it off with a
clean lint-free cloth, paper towel or
similar material
4 Carefully push the dipstick all the way
into the guide tube and pull it out
again
5 The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil quantity between the two marks
on the dipstick corresponds to approx.
1.1 US quarts (1 liter).
To add oil Wait until the level has dropped to just
above the lower mark before adding oil.
However, never let the oil drop below
the lower mark.
Do not fill beyond the upper mark on
the dipstick. Excess oil will damage the
engine.
BMW engines are designed to
operate without oil additives; the
use of additives could lead to damage
in some cases. This is also true for the
manual transmission, the differential,
and the power steering system.<
Recommendation: have the oil changed
by your BMW center only.

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety Ð and as cost-effectively as
possible for you.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle. Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals. These are then indicated in
the Service Interval Display. While
conventional systems rely on distance
traveled alone to determine when
service is due, the BMW Maintenance
System has for years considered the
actual conditions under which the
vehicle operates, because miles can be
traveled in many different ways: for
example, 62,000 miles (100,000 km) of
short-distance driving are not equal to
the same 62,000 miles (100,000 km) of
long-distance travel. In response to this
fact, the BMW Maintenance System
monitors operating conditions as the
basis for determining the service inter-
vals for your vehicle, it includes the
Engine Oil Service and Inspections I
and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. Those who drive fewer than
6,000 miles (10,000 km) per year
should, nevertheless have their oil
changed every 2 years at the most, no
matter what the Service Interval Display
indicates, since engine oil ages over
time, regardless of loading. Service and Warranty Information
Booklet (US models)/Warranty
and Service Guide Booklet
(Canadian models)For additional information on required
maintenance intervals and procedures,
please refer to the Service and Warranty Information Booklet (US
models), or the Warranty and Service
Guide Booklet (Canadian models).
As a precaution against rust, it might be
a good idea to have the body checked
for damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW center do the
maintenance and repair.
Your BMW center is always "up to date"
on the latest maintenance work and
repair techniques and equipped with
the required special tools. In addition,
checking parts known from experience
to be subject to wear is a permanent
part of the maintenance specifications.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet (US models), or in
the Warranty and Service Guide Book-
let (Canadian models). These entries
are your proof that the vehicle has
received regular maintenance. They
are also a requirement for warranty
claims.<
The BMW Maintenance System

128n
Washing your vehicle You can have your BMW washed in an
automatic car wash, even when it is
new. Car wash systems that do not
employ brushes are preferable.
Wipe away tough dirt and loosen and
remove dead insects before washing
the vehicle.
To prevent spots, avoid washing when
the hood is still warm, or immediately
after and during exposure to strong
sunlight.
When using an automatic car wash, be
sure that:
>The car wash system is suited for the
dimensions of your vehicle
>No damage will occur on vehicles
with attached body accessories (such
as spoilers or antennas). Consult the
car wash operator if necessary
>The wheels and tires of your vehicle
cannot be damaged by the convey-
ance devices of the car wash system
>The vehicle is cleaned with minimum
brush pressure, and that plenty of
water is available for washing and
rinsing. Vehicles with rain sensor:
Clean the windshield regularly. Wax
from automatic car washes or insects
can cause malfunctions in the rain
sensor function.
Turn the rain sensor off (refer to
page 66) when going through an
automatic car wash, otherwise, damage
could occur from unintended wiper
activation.<
Parts of the vehicle which are inacces-
sible to the automatic washer Ð such
as door sills, door and hood edges, etc.
Ð should be cleaned by hand.
In the winter months, it is especially
important to ensure that the vehicle is
washed on a regular basis. Large
quantities of dirt and road salt are
difficult to remove, and they also cause
damage to the vehicle.
If spray wands or high-pressure
washers are used, be sure to
maintain an adequate distance between
the spray source and the vehicle's
surface. Inadequate distance and
excessive pressure can damage or
weaken the finish, making it more
susceptible to subsequent attack. In
addition, moisture could penetrate to
vehicle components, leading to long-
term damage.<
When cleaning the headlamps,
please observe the following:
Do not wipe dry with a cloth
(scratches). Never use abrasives or
strong solvents. 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.<
After washing the vehicle, apply
the brakes briefly to dry them.
Braking efficiency might otherwise be
reduced by the moisture and the brake
rotors could also corrode.<

Caring for your vehicleExterior finish To provide effective corrosion protec-
tion, multilayer paintwork is applied at
the factory. Cataphoretic immersion
priming techniques are supplemented
with special body-cavity protectants, by
applying specially developed and
extensively tested materials.
A layer of flexible PVC is first applied to
the undercarriage. Following this, a
comprehensive undercoating treat-
ment with a wax-based protectant is
applied. Regular maintenance makes
an important contribution to maintaining
the safety and value of your vehicle.
Increasing awareness of the effects of
harmful environmental factors on
vehicle finishes have led paint and
vehicle manufacturers to initiate
programs designed to further improve
the durability of their finishes. Despite
this, regional environmental factors can
have negative effects on your vehicle's
finish. These should guide you in deter-
mining the frequency and extent of your
efforts to maintain the vehicle finish.
Depending upon material and type of
impact (perforation of paint layer),
physical stresses from sand, road salt,
gravel etc., can cause corrosion to
extend beneath the finish, starting at
the point of impact.Road dirt, tar spots, dead insects,
animal droppings (strong alkali effect)
and tree excretions (resins and pollen)
all contain substances capable of
causing damage when allowed to
remain on the finish of your vehicle
for any period of time (spots, etching,
flaking, separation in the top coat).
In industrial areas, deposits of flue dust,
lime, oily soot, precipitation containing
sulfur-dioxide (acid rain) and other
environmental pollutants will damage
the vehicle's finish unless adequate
care is provided Ð even though this
is generally limited to the outside hori-
zontal surfaces.
In coastal regions, high levels of
atmospheric salt and humidity promote
corrosion.
In tropical zones, high humidity and
heavy ultraviolet radiation prevail, in
addition to temperatures of over 105 7
(+40 6) in the shade. Under these
conditions, light paints can reach tem-
peratures up to 175 7 (+80 6) and
dark ones up to 250 7 (+120 6).
Caring for the vehicle finish Regular washing is a preventive
measure against long-term effects from
substances that are harmful to the
vehicle's finish, especially if you drive
your vehicle in areas with high levels
of air pollution or aggressive natural
substances (tree resins, pollen).
Nevertheless, you should immediately
remove especially aggressive
substances. Failure to do so can lead to
changes in the paint's chemical
structure or to discoloration. Gasoline
spilled during refueling, oil, grease and
brake fluid should always be cleaned
away immediately, as should bird
droppings (finish damage).
Any contamination remaining on the
surface of the vehicle will be especially
conspicuous after washing. Use
cleaning fluid or alcohol with a clean
cloth or cotton pad to remove. Remove
tar spots with tar remover. After
cleaning, the affected areas should be
waxed to ensure continued protection.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<

130n
Caring for your vehicleWaxing your vehicle Protect the finish using only carnauba
or synthetic-based waxes.
The best way to determine when the
finish needs to be waxed is by noting
when water stops beading on the
surface.
You can use a glass cleaner to remove
any wax or silicone that may have been
left on the windows during waxing.
Use the 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 vehicle is
provided on a sticker located on the
right hand side under the hood and on
the first page of your Service and
Warranty Information Booklet (US
models) or Warranty and Service Guide
Booklet (Canadian models).
Damage caused by flying stones,
scratches, etc., must be touched up
without delay to prevent rust from
forming.
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
accordance with the manufacturer's
instructions. Your BMW center uses
original BMW finish materials in
accordance with factory-approved
repair procedures.
Window careYou 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.
Clean the wiper blades with soapy
water. The wiper blades should be
replaced twice a year Ð before and after
the cold season. This is especially
important for vehicles equipped with
rain sensor.
Use only wiper blades approved
by BMW.<

Caring for your vehicleCaring for other vehicle
components and materials Light-alloy wheels should be treated
with alloy wheel cleaner, especially
during the winter months. However, do
not use aggressive products contain-
ing 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 window moldings, door handles or
similar items, clean these parts carefully
with ample clean water, and possibly a
shampoo additive, especially if there is
an accumulation of road salt. Use
chrome polish as an additional treat-
ment.
Plastic components, vinyl upholstery,
headliners, lamp lenses, the clear cover
of the instrument cluster and compon-
ents with a sprayed dull black surface
can be cleaned with water (add plastic
shampoo as required). Do not allow
moisture to soak through the seats or
headliner. Never use solvents such as
lacquer thinner, heavy-duty grease
remover, fuels, or similar substances.
Rubber components should be cleaned
with water only; a rubber treatment or
silicone spray may also be applied. The safety belts should be cleaned with
a mild soap and water solution without
being removed from the vehicle. Never
attempt chemical or dry cleaning, as
damage to the belt fabric could result.
After cleaning, never allow the inertia
reel to retract the belts until they are
completely dry. Dirty safety belts pre-
vent the inertia reel mechanism from
retracting the strap properly, and thus
constitute a safety hazard.
Heavily soiled floor carpets and mats
*
can be cleaned with an interior cleaner.
The floor mats can be removed from
the vehicle for cleaning.
Use only a damp cloth to clean trim
panels made of real wood
* and other
parts constructed of real wood
*. Follow
up by drying with a soft cloth.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<
Care of upholstery materials Depressions in the upholstery that
result from everyday use can be
brushed smooth by brushing against
the nap with a lightly dampened brush.
The tendency of the pile to lie in a par-
ticular direction on velour upholstery is
not a quality defect. Just as with home
textiles or clothing, this cannot be
avoided.
Lint on upholstery materials, textile or
leather remnants that have been worn
into the upholstery may be removed
with a lint brush or a Velcro brush. A
cleaning glove is available for particu-
larly "stubborn" lint. Stains and fairly
large areas of dirt should be cleaned off
without delay, using lukewarm water
and an interior cleaner, stain remover or
appropriate cleaning fluid. Brush the
fabric afterwards to restore its appear-
ance.
If the vehicle will be stored for an
extended period or if it is exposed to
intense sunlight, cover all the seats or
the windows to prevent fading.
Use the cleaning and car-care
products that you can obtain at
your BMW center.<

OBD connector The data link connector for onboard
diagnostics is located on the left-hand
side of the driver's side, on the under-
side of the instrument panel and under
a cover panel. The cover is marked with
the letters "OBD".
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.
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
nearest BMW center immediately.
Severe engine misfire over even a short
period of time can seriously damage
emission control system components,
especially the catalytic converter.
"Service Engine Soon" warning
lamp for Canadian models.
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.<

Repairing a flat tire Battery 8 Take out the hose with the pressure
gauge and screw it onto the valve.
Take out the plug and plug it into the
cigarette lighter socket in the
passenger compartment
9 Inflate the tire pressure:
>To increase the tire pressure: turn
on the M Mobility system
(position I). To check the new tire
pressure briefly turn off the device
>To reduce the tire pressure: turn
the screw on the back of the pres-
sure gauge; this will open the air
release valve
If the air pressure won't hold, still
carry out step 10 and then repeat
steps 7 through 10 again.
The use of the M Mobility system may
be ineffective if the damaged area in
the tire is larger than approx. 0.16 in
(4 mm). Please consult the nearest
BMW center if the tire cannot be
temporarily repaired with the M Mobility
system.<
10 Unscrew the hose from the valve
and stow the M Mobility system in
the luggage compartment.
After the flat tire has been fixed and you
start driving again, do not exceed a
maximum speed of 50 mph (80 km/h).
You will find corresponding instructions
for using the M Mobility system on the
device.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced. Re-initialize the Tire Pressure
Warning system (RDW), refer to
page 78 for further information. Have
the M Mobility system refilled. Contact
your BMW center for this.
Battery locationThe battery is located at the right-rear
of the luggage compartment. Raise the
luggage compartment floor panel (refer
to page 39). Using a screwdriver or a
coin and f turn, release both of the
caps as shown in the illustration, taking
them out along with an additional cap in
the top center of the right side trim
panel. Remove the fasteners. In order
to remove the storage tray, slide the
side trim panel slightly upward.
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<

Battery
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.
Be sure that children keep well
away from batteries and battery
acid.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If your skin or clothing are
splashed with acid, rinse immediately
with plenty of soap and water. If acid is
accidentally swallowed, consult a
physician immediately.
Removal and installation
Do not disconnect the battery
when the engine is running.
Disconnecting the battery cable when
the engine is running will cause a
voltage surge which will damage the
vehicle's onboard electronics. 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. Repairs
and disposal may only be performed by
specially-trained personnel.<
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
adequately secured in case of an acci-
dent.<
Charging the battery Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the
battery, charge it and store it in a cool
and dust-free room where there is no
danger of freezing. During storage,
have the battery recharged every 3
months. Also, recharge the battery
before it is reinstalled. If this is not
done, the battery will not be service-
able. Every time the battery is drained,
especially over extended periods, its
service life is reduced.
