Starting the engineBefore starting>Engage the parking brake
>Be sure that the gearshift lever is in
"Neutral" (or the selector lever in "P"
if the vehicle is equipped with auto-
matic transmission)
>Depress the clutch pedal.
Do not run the engine in enclosed
spaces. The exhaust gases
contain carbon monoxide, an odorless
and colorless, but highly toxic gas.
Breathing the exhaust gases poses an
extreme health risk, and can lead to
unconsciousness and death.
Do not leave the vehicle unattended
with the engine running. An unattended
vehicle with a running engine repre-
sents a potential safety hazard.<
Starting the engine>Do not press the accelerator pedal
while starting the engine.
Do not actuate the starter for too
short a time. Do not turn it for
more than approx. 20 seconds. Release
the ignition key immediately after the
engine starts.
Do not allow the engine to warm up
by leaving it running while the vehicle
remains stationary. Instead, begin to
drive immediately at a moderate engine
speed.<
Should the engine fail to start on the
first attempt (if it is very hot or cold, for
instance):
>Press the accelerator pedal halfway
down while engaging the starter.
Cold starts at very low temperatures,
from approx. +5 7 (Ð15 6) and at
altitudes above approx. 3,300 ft
(1,000 m):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
If these temperature conditions are
anticipated for a longer period, have the
engine oil changed to a special oil, refer
to page 124. Please contact your BMW
center for additional information.
Usually, it is not necessary to depress
the accelerator pedal. However, at high
altitudes or in very hot or very cold
weather, depress the pedal halfway
down when starting the engine.
Engine idle speed is controlled by the
engine computer system. Increased
speeds at start-up are normal and
should decrease as the engine warms
up. If engine speed does not decrease,
service is required.
To prevent the battery from
discharging, always switch off any
accessories which are not required.
Switch off the ignition when the vehicle
is not being driven.

Engine oilSpecified engine oilsThe quality of the engine oil which is
selected has critical significance for the
operation and service life of an engine.
Based on extensive testing, BMW has
approved only certain engine oils.
Use only approved "BMW High Perfor-
mance Synthetic Oil".
If you are unable to obtain "BMW High
Performance Synthetic Oil", you can
add small amounts of synthetic oil in
between oil changes. Only use oils with
the API SH specification or higher.
Ask your BMW center for details
concerning the specific "BMW
High Performance Synthetic Oil" or
"synthetic oils" which have been
approved.<
You can also call BMW of North
America at 1-800-831-1117 or visit this
website: www.bmwusa.com to obtain
this information.
Viscosity Ð ratingsViscosity is the oilflow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you drive your BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be utilized in all ambient
temperatures.

Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing. Any skin areas that come in
contact with oil should thus be thor-
oughly washed with soap and water.
Store oil, grease, etc., out of reach of
children. Comply with warning labels
and information on containers.
If you use SAE 15W-40 engine oil in low
temperatures (below +14 7/Ð10 6),
the engine may become difficult to
start.
Special engine oils individually
approved by BMW are preferred for use
in your engine. Please contact your
BMW center for details.<
Do not add coolant to the cooling
system when the engine is hot. If
you do, escaping coolant can cause
burns.
To avoid the possibility of damage later
on, do not use anything other than
factory-approved, nitrite and amino-
free extended-duty antifreeze with
corrosion inhibitor which can be used
with aluminum radiator cores. Your
BMW center is familiar with the
approved specifications.
Antifreeze and anti-corrosion agents
are hazardous to health. Store them in
their original containers. Keep the
containers tightly closed and out of
reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethylene glycol. For this
reason, do not spill extended-duty anti-
freeze with corrosion inhibitor on hot
engine components. If you do, it could
be ignited and cause burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
Checking coolant levelCorrect coolant level when the engine
is cold (approx. +68 7/+20 6):
Unscrew the cap from the expansion
tank.
The coolant level is correct when the
upper end of the red float is at least
even with the upper edge of the filler
neck (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm)
above it Ð that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).367de356

The BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and oper-
ating 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 your vehicle.

Service Interval DisplayAdvanced technology is employed to
calculate the optimal maintenance
intervals, which are then indicated in
the Service Interval Display. While
conventional systems rely solely on
distance traveled to determine when
service is due, the BMW Maintenance
System considers the actual conditions
under which the vehicle operates.
From the point of view of maintenance,
62,000 miles (100,000 km) accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel. In response
to this fact, the BMW Maintenance
System monitors operating conditions
as the basis for determining the
optimum service intervals for your indi-
vidual vehicle. The BMW Maintenance System
includes the Engine Oil Service as well
as Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, since oil deteriorates
over time regardless of use, even those
who drive only short distances Ð signiÞ-
cantly less than 6,200 miles (10,000 km)
annually Ð should have the engine oil
changed regularly. Refer to the Service
and Warranty Information Booklet (US
models) or to the Warranty and Service
Guide Booklet (Canadian models).

Airbags Storing your vehicle1 Front airbags on the driver and
passenger side
2 Side airbags on the driver and
passenger sideImportant safety notices
Do not attempt to remove the gas
generators of the airbag restraint
system from the vehicle or to disas-
semble them.
Have inspection and service proce-
dures performed by specially-trained
personnel only.
If the airbag restraint system malfunc-
tions, is deactivated or triggered as a
response to an accident, have the
system repaired by a BMW center only.
367de730
Do not make modifications of any kind
to the individual components or system
wiring. These include the upholstered
covers on the steering wheel hub, in the
instrument panel and in the side trim
panels of the doors. Never apply adhe-
sive materials to these components or
cover or modify them in any way. Do
not attempt to disassemble the steering
wheel itself.
To ensure compliance with applicable
safety regulations, have the airbag
generators disposed of by a BMW
center only.
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.< If you intend to store the vehicle
for longer than three months, have
the maintenance operations described
on this page performed.<
Preparation for storageHave the following operations
performed by your BMW center:
1. Clean and apply a rust-proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the rubber
seals around the hood, luggage
compartment and doors
2. Change the engine oil and oil filter
with the engine at operating temper-
ature. As an additional corrosion
protection measure, an anticorrosive
agent can be added to the engine in
accordance with the manufacturer's
instructions
3. Check the coolant level and concen-
tration and top up if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top up if
necessary
