You can also call BMW of North America at
1-800-831-1117 or visit the website
www.bmwusa.com to obtain this information.Do not use oil additives, as these may
cause engine damage. <
Alternative oil types
If exceptionally none of the approved oils hap-
pens to be available, sm all quantities of other
oils may be used when adding oil between oil
changes. However, the corresponding con-
tainer must be labeled with one of the following
oil specifications:
Gasoline engines
> Preferred: BMW Longlife-01,
BMW Longlife-01 FE or BMW Longlife-04
> Alternatively: BMW Longlife-98, API SM or
higher
Diesel engines
BMW Longlife-04
Viscosity ratings
Viscosity is a measure of an oil's flow rating and
is categorized in SAE classes.
Selecting the appropriate SAE class depends
on the regional climatic conditions in which you
normally drive your BMW.
Approved oils belong to the 0W-40,
0W-30, 5W-40 and 5W-30 SAE
classes. <
These oils can be used fo r driving at all outside
temperatures.
Coolant
Do not add coolant to the cooling system
when the engine is hot. Escaping coolant
can cause burns. <
Coolant consists of half water and half additive.
Not all commercially availa ble additives are suit-
able for your BMW. Ask your BMW center for
suitable additives. Only use suitable additives, otherwise en-
gine damage may re
sult. Because addi-
tives are harmful to your health, it is important to
follow the instructions on the containers. <
Comply with the appropriate environ-
mental protection regulations when dis-
posing of coolant additives. <
Checking coolant level
1.Do not open the engine hood before the en-
gine has cooled down.
2. Turn the cap of the expansion tank a little
counterclockwise to allow any accumulated
pressure to escape, then continue turning
to open.
3. The coolant level is corr ect if it is between
the maximum and minimum marks in the
filler neck, refer also to the diagram next to
the filler neck.
4. If the coolant is low, slowly add coolant up to
the specified level; do not overfill.
5. Turn the cap until there is an audible click.
6. Have the reason for the coolant loss elimi-
nated as soon as possible.

Maintenance
BMW Maintenance System
The BMW Maintenance System supports the
preservation of the traffic and operating safety
of your BMW. The objective is to optimize
efforts with respect to minimal vehicle mainte-
nance costs.
If and when you come to sell your BMW, a com-
prehensive record of servicing will prove a sig-
nificant benefit.
Condition Based Service CBS
Sensors and special algo rithms take the differ-
ent driving conditions of your BMW into
account. Condition Based Service uses this to
determine the current and future service
requirements. By letting you define a service
and maintenance regimen that reflects your
own individual requirem ents, the system builds
the basis for trouble-free driving.
On the Control Displa y, you can have the
remaining times or distan ces for selected main-
tenance tasks and any le gally prescribed dates
displayed, refer to page 71:
> Engine oil
> Brake pads: separately for front and rear
> Brake fluid
> Vehicle check
> Legally mandated in spections depending
on local regulations
> Diesel particulate filter
*
Service data in the remote control
Your vehicle continuo usly stores service-
requirement information in the remote control
while you are driving. Your BMW Service Advi-
sor can read out this da ta from the remote con-
trol unit, and propose an optimized mainte-
nance approach. Whenever you take your car in
for servicing you should therefore hand your
BMW Service Advisor the remote control unit
that you last used.
Make sure that the date is always set cor-
rectly, refer to page 74; otherwise the
effectiveness of Condit ion Based Service CBS
is not assured. <
Service and Warranty Information
Booklet for US models and Warranty
and Service Guide Booklet for
Canadian models
Please consult your Service and Warranty Infor-
mation Booklet for US models and Warranty
and Service Guide Booklet for Canadian models
for additional information on service require-
ments.
BMW recommends that you have service
and repair operations performed at your
BMW center.
Take the time to ensure that these service pro-
cedures are confirmed by entries in your vehi-
cle's Service and Warranty Information Booklet
for US models and Warranty and Service Guide
Booklet for Canadian models. These entries
verify that your vehicle has received the speci-
fied regular maintenance. <

Socket for On-Board
Diagnosis OBD
Primary components that make up exhaust
emissions can be checked by a device via the
OBD socket.
This socket is located on the driver's side to the
left, on the bottom of the instrument panel
underneath a cover.
Exhaust emission values
The warning lamp lights up:
The exhaust emission values have
worsened. Have the car checked as
soon as possible.
Canadian models display this warning
lamp.
The lamp flashes under certain conditions. This
indicates excessive misfir ing in the engine. If
this happens, you should reduce your speed
and visit your nearest BMW center as soon as
possible. Severe engine misfiring can quickly
lead to serious damage of emissions-related
components, especially the catalytic converter.
The warning lamp comes on if the gas
cap is not properly tightened and the
OBD system assumes that fuel vapor
is escaping. If the gas ca p is then tightened, the
warning lamp should go out within a few days.
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring or diagnostic modules or a
device for recording or sending certain vehicle
data or information. In addition, if you have
signed a service contract for BMW Assist, cer- tain vehicle data ma
y be transmitted or
recorded in order to fa cilitate the corresponding
services.

Care
Care products
Regular cleaning and care contributes signifi-
cantly to the value retention of your BMW.
BMW recommends cleaning and caring for your
vehicle with products that are approved by
BMW for this purpose.
Your BMW center will be happy to advise you on
the products and services available for cleaning
and caring for your BMW.
Original BMW CareProducts have been
material tested, labo ratory checked and
proven in the field, and offer optimal care and
protection for your vehicle. <
Do not use cleaners that contain alcohol
or solvents as these may result in dam-
age.<

that are dangerous or hazardous to your
health. Therefore, follow the warning and safety
instructions on the packaging. When cleaning
inside the vehicle, always open the doors or
windows of the vehicle. In enclosed areas, pro-
vide for sufficient ventilation. Only use products
designed for cleaning vehicles. <
Exterior care
Washing the vehicle
Especially during the winter months,
ensure that the vehicle is washed more
frequently. Heavy soiling and road salt can lead
to vehicle damage. <
After washing the vehicle, apply the
brakes briefly to dry them, otherwise
water can reduce braking efficiency over the
short term and the brake discs can corrode. <
Automatic car washes
Preference should be given to cloth car washes.
Before driving into a car wash, ensure that it is
suitable for your BMW. Check the following: >
Dimensions of your vehicle, refer to
page 239
> If necessary: fold in the exterior mirrors,
refer to page 47
> Maximum permissible tire width
Preparations before driv ing into an automatic
car wash:
> Unscrew the rod antenna
*.
> Deactivate the rain sensor
* to prevent unin-
tentional wiping.
> Sports Wagon: deactivate the rear window
wiper and protect it against damage. If nec-
essary, ask the operator of the car wash
about protective measures you should take.
> Remove additional attachments, e.g.
spoiler or telephone an tennas, if there is a
possibility that they could be damaged.
Automatic transmission
Before driving into an automatic car wash, per-
form the following steps to ensure that the vehi-
cle can roll:
1. Insert the remote cont rol, even with conve-
nient access, into the ignition lock.
2. Move the selector lever to position N.
3. Release the parking brake.
4. Switch off the engine.
5. Leave the remote control in the ignition lock
so that the vehicle can roll.
Steam jets / high -pressure washers
When using steam jets or high-pressure
washers, ensure that you maintain suffi-
cient clearance to the vehicle and do not exceed
a temperature of 140 7/60 6.
Insufficient clearance or excessive pressure or
temperature can lead to component damage or
water penetration. Follow the operating instruc-
tions of the high-pressure washer. <
When using high-pressure washers, do
not spray against the sensors and cam-
