Fuel specifications Tire inflation pressure The engine uses lead-free gasoline
only. However, you can refuel with dif-
ferent fuel qualities since the engine is
equipped with knock sensors.
In order to achieve rated values for
engine performance and fuel consump-
tion:
>Super lead-free premium gasoline
(91 AKI).
AKI = Anti Knock Index
The minimum fuel quality is:
>Regular lead-free gasoline (87 AKI).
Because of the engineÕs design, you
should refuel with this gasoline only
as an exception.
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
You will find tire inflation pressures on
the inside door pillar. Check tire pressures All pressure specifications are indicated
in psi (kilopascal) for tires at ambient
temperature (refer also to the next
page). 530us009
Check tire inflation pressures reg-
ularly Ñ at least every two weeks
and before beginning a longer trip. In-
correct tire pressure can otherwise lead
to tire damage and accidents.
Check the tire inflation pressure of the
spare wheel. Inflate the spare tire to the
highest inflation of any tire on your vehi-
cle.<
Comply with tire approval
specifications The inflation pressures in the table ap-
ply to tires from BMW-approved manu-
facturers. Your BMW center is familiar
with these pressures. Higher pressures
may be specified for tires from other
manufacturers. You will find a list of
approved tires beginning on page 132.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW approved
tires.

Tachometer Energy control Fuel gauge Do not operate the engine with the
needle in the red overspeed zone of the
gauge.
To protect the engine, the engine-man-
agement system automatically inter-
rupts the fuel supply in this range; the
resulting effect resembles that associ-
ated with a sudden loss of power. 390us004
Indicates the current fuel consumption
in mpg (in liters/100 km on Canadian
vehicles). This allows you to see
whether your current driving style is
conducive to fuel economy with mini-
mum exhaust emissions.
When the vehicle is stationary, the
display goes to "Maximum" (zero on
Canadian models). 390us005
When you switch on the ignition, the in-
dicator lamp comes on briefly to con-
firm that the system is operational.
If the indicator lamp comes on and
stays on, there are approx.
>2.6 gallons (10 liters)
of fuel still in the tank.
Tank capacity: refer to page 187.
Certain operating conditions (such as
those encountered in mountainous ar-
eas) may cause the needle to fluctuate
slightly.
Please refuel early, as driving to
the last drop of fuel can result in
damage to the engine and/or catalytic
converter.< 390us006

General driving notes Catalytic converter
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Aquaplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as aquaplaning
or hydroplaning. It is characterized by a
partial or complete loss of contact be-
tween the tires and the road surface.
The ultimate results are loss of steering
and braking control.
Cargo area cover:
Do not place heavy or hard objects on
the cargo area cover. These objects
could endanger vehicle occupants dur-
ing heavy brake applications or evasive
maneuvers.
Clothes hooks:
When suspending articles of clothing
from the hooks, be sure that they will
not obstruct the driver's vision. Do not
hang heavy objects on the hooks. If you
do so, they could cause personal injury
during braking or evasive maneuvers.< The catalytic converter reduces harmful
exhaust emissions.
It is designed for use with unleaded fuel
only. Even minute quantities of lead
would be enough to permanently dam-
age both the catalytic converter and the
system oxygen sensor.
To ensure efficient, trouble-free engine
operation and avoid potential damage:
>Be sure to comply with the scheduled
maintenance requirements.
>Fill the fuel tank well before it is
empty.
>When the battery is discharged, start
the engine with an outside starting
aid.
>Avoid other situations in which the
fuel is not burned, or burns incom-
pletely, such as engaging the starter
frequently or for extended periods, or
repeated start attempts in which the
engine does not start (stopping and
restarting an engine which is running
properly does not present a problem).
Never allow the engine to run with
any of the spark plug cables discon-
nected.

Catalytic converter Antilock Brake System (ABS)
Be sure to comply with the in-
structions above to prevent un-
burned fuel from reaching the catalytic
converter. Otherwise, the catalytic con-
verter could respond by overheating,
leading to serious damage.
Extreme temperatures occur at the cat-
alytic converter on this and every cata-
lyst-equipped vehicle. Heat shields are
installed adjacent to some sections of
the exhaust system. Never remove
these shields; do not apply undercoat-
ing to their surfaces. When driving,
standing at idle, and parking the vehi-
cle, take care to avoid contact between
the exhaust system and flammable ma-
terials (grass, hay, leaves, etc.). Such
contact could lead to a fire, resulting in
serious personal injury and property
damage.<
The concept ABS enhances active safety by helping
to prevent the wheels from locking un-
der braking. This is because: locked
wheels are dangerous. When the front
wheels slide, the driver loses steering
control over the vehicle. Traction loss at
the rear wheels can cause the rear end
to break into an uncontrolled skid.
With ABS, you will achieve the shortest-
possible braking distances under all
given conditions (braking while driving
straight ahead or in curves, different
road surfaces).
ABS is designed to meet two essential
requirements during every brake appli-
cation:
>To help provide vehicle stability.
>To help retain steering and maneu-
vering capability on all types of road
surfaces (asphalt, cement, dirt, wet
surfaces, snow and ice).
Braking with ABS The system becomes operative once
the vehicle exceeds a speed of approx.
6 mph (10 km/h). The ABS is deactivated
whenever the vehicle's speed drops
back below approx. 4 mph
(6 km/h).
To shorten the braking distance Ñ espe-
cially on steep, poor road surfaces when
driving slowly straight ahead Ñ the sys-
tem allows one or both front wheels to
lock for a short time. Nevertheless, the
vehicle still retains steering response
since this "poor road logic" is deacti-
vated again automatically as you steer.
If you are in a situation that requires full
braking, you will exploit the full beneÞts
of the ABS system if you apply maxi-
mum brake pressure ("panic stop").
Since the vehicle maintains steering
responsiveness, you can avoid possible
obstacles with a minimum of steering
effort, despite the full brake application.
The ABS system's closed-loop control
circuit cycles in fractions of a second.
A pulsation at the brake pedal, together
with the sounds associated with the
hydraulic controls, tells you that the
brake system is within its maximum
limit range and reminds you that you

OBD interface socket The Onboard Diagnostic (OBD) inter-
face socket is located on the left of the
driver's side at the bottom of the instru-
ment panel and under a cover.
The cover has the letters "OBD" on it.
The purpose of the OBD system is to
ensure proper operation of the emis-
sion control system for the vehicle's
lifetime. The system monitors emission-
related components and systems for
deterioration and malfunction. 530us105
An illuminated lamp informs you
of the need for service, not of
the need to stop the vehicle.
However, the systems should be
checked by your BMW center at the
earliest possible opportunity.
Under certain conditions, the indicator
will blink or flash. This indicates a rather
severe level of engine misfire. When
this occurs, you should reduce speed
and consult the nearest BMW center as
soon as possible. Severe engine misfire
over only a short period of time can
seriously damage emission control
components, especially the catalytic
converter.
Warning lamp, Service Engine
Soon for Canadian models.
When the filler cap is not properly
tightened, the OBD system can
detect the vapor leak and the indicator
will light up. If the filler cap is subse-
quently tightened, the indicator should
go out within a few days.<
