For your own safety

Use unleaded gasoline only. Fuels
containing up to and including
10% ethanol or other oxygenates with
up to 2.8% oxygen by weight (i.e.
15% MTBE or 3% methanol plus an
equivalent amount of co-solvent) will
not void the applicable warranties
respecting defects in materials or work-
manship. Field experience has indi-
cated significant differences in fuel
quality (i.e. volatility, composition or
additives, etc.) among gasolines offered
for sale in the United States and
Canada. The use of poor-quality fuels
may result in driveability, starting and
stalling problems especially under
certain environmental conditions such
as high ambient temperature and high
altitude.
Should you encounter driveability prob-
lems that you suspect could be related
to the fuel you are using, we recom-
mend that you respond by switching
to a recognized high-quality brand.
Failure to comply with these recom-
mendations may result in unscheduled
maintenance.
Follow the relevant safety rules when
you are handling gasoline.

Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by "

l

" are tested for proper
functioning whenever the ignition key is
turned. They each light up once for
different periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started or
it lights up while the vehicle is moving.
You will see how to react to this in the
following section.

Red: stop immediately

Battery charge current

l

The battery is no longer being
charged. The alternator drive
belt is defective or there is a malfunc-
tion in the charging circuit of the alter-
nator. Please contact the nearest BMW
center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and
serious engine damage. If the drive belt
is defective, increased steering effort is
also required.

<


Engine oil pressure

l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level and top off as
required. If the oil level is correct,
please contact the nearest BMW
center.
Do not continue driving, as the
engine could sustain serious
damage from inadequate lubrication.

For maximum safety, please comply
with the following:
Never try to adjust your seat while
operating the vehicle. The seat
could respond with an unexpected
movement, and the ensuing loss of
vehicle control could result in an acci-
dent.
Be sure that the safety belt is fastened
firmly against your body at all times. In
the event of a frontal impact, a loose lap
belt could slide over your hips, leading
to abdominal injury. In addition, the
safety belt's restraint effectiveness is
reduced if the belt is worn loosely.
When adjusting your seat, select a
position that provides the maximum
distance between you and the steering
wheel, instrument panel and door while
still allowing comfortable and safe
access to all vehicle controls.<
Correct sitting postureTo reduce strain on your spinal column,
sit all the way back in the seat and rest
your back fully against the backrest.
In the ideal sitting posture, your head
extends along a straight line from your
spine.
For long-distance driving, you may wish
to increase the backrest tilt angle
slightly to reduce muscular tension.
You should also be able to grasp the
highest point of the steering wheel with
your arms slightly bent.
After a seat adjustment in the coupe,
adjust the height of the safety belt also,
refer to page 52.1 Height

Airbags1 Front airbags on the driver and
passenger side
2 Side airbags on the driver and
passenger sideProtective effectThe front airbags help protect the driver
and passenger in the event of a head-
on collision where the protection
provided by the safety belt alone would
not be adequate. The side airbags help
provide protection in the event of a side
collision. Each side airbag provides
support to the side chest area.367de730
The illustration depicts schematically
the primary directions of vehicle impact
which initiate airbag deployment.
The airbags will not be triggered in
the event of a minor accident, a
vehicle roll-over, or an impact from the
rear.< 367de736
Operational readiness
The indicator lamp in the instru-
ment cluster shows the airbag-
system's operational readiness
starting with ignition key position 1.
System operational:
>The indicator lamp comes on briefly.
System malfunction:
>The indicator lamp fails to come on
>The indicator lamp comes on briefly
before going out and then lighting up
again.
A system malfunction could prevent the
system from responding to a high-
intensity frontal impact occurring within
its normal response range.
Please have your BMW center inspect
and repair the system as soon as
possible.

AirbagsSitting correctly with airbags
For your safety, comply with the
following instructions for the
airbags. If you do not, the airbags may
not be able to provide their maximum
protection. All passengers in the vehicle
should be aware of and comply with this
information:
The airbags are supplemental restraint
devices designed to provide extra
protection; they are not a substitute for
safety belts. Wear your safety belt at
all times.
Adjust your seat to a position that is
comfortable for you, allowing unre-
stricted vehicle operation, and is not
closer to the steering wheel than neces-
sary.
Always grasp the steering wheel by the
steering wheel rim, keeping your hands
at the "9-o'clock" and "3-o'clock" posi-
tions in order to minimize any risk of
injury to hands or arms if the airbag does
deploy.
There should not be any other persons,
animals or objects between the airbag
and the passenger in that seat.
Do not use the cover panel for the front
airbag on the passenger side as a
storage area.
Do not apply adhesive materials to the
cover panels of the airbags, cover them
or modify them in any other way.
If you use a child-restraint system, read
carefully and comply with the instruc-
tions on page 56.
Be sure that child-restraint systems are
installed correctly and with the greatest
possible distance from the airbag in the
side trim panel. Do not allow children to
lean out of the child-restraint system in
the direction of the side trim panel.
Otherwise, serious injuries could occur
if the airbag is triggered.<
Even when you have complied with all
of these guidelines, there is still a small
residual risk of minor facial, hand and
arm injuries from airbag deployment
occurring in isolated instances.
The ignition and inflation noise may
cause a mild temporary hearing loss in
extremely sensitive individuals.
Corresponding airbag safety precau-
tions are provided on both sun visors
and the instrument panel (US models).
For additional information concerning
the airbag system, refer to pages 130
and 164.This is the correct way a child should sit
in a child restraint when side airbags
(arrow) are provided.

Cruise control
*
You can maintain and store any desired
vehicle speed above approx. 25 mph
(40 km/h).
The system is switched off and the
stored speed deleted from its memory
when you turn the ignition key to posi-
tion 0.
Do not use the cruise control on
winding roads, when high traffic
density prevents driving at a constant
speed, when the road surface is slick
(snow, rain, ice) or when the road
surface is loose (rocks or gravel,
sand).< 365us059
To maintain and store speed/
to acceleratePress the lever briefly in direction 1:
The system maintains and stores the
current vehicle speed. Every time you
briefly press the lever, the speed
increases by approx. 0.6 mph (1 km/h).
Hold the lever in position 1:
The vehicle accelerates without pres-
sure on the accelerator pedal. When
you release the lever, the system main-
tains and stores the current speed.
If, on a downhill grade, the engine
braking effect is not sufficient, the
controlled speed can be exceeded.
Speed can drop on uphill grades if the
engine output is insufficient.< To deceleratePress the lever briefly in direction 2:
If you are already driving with active
cruise control, the speed is decreased
by approx. 0.6 mph (1 km/h) every time
you briefly touch the lever.
Hold the lever in position 2:
With the cruise control active, the
system automatically reduces the
throttle opening to slow the vehicle.
When you release the lever, the system
maintains and stores the current speed.Call up stored setting (resume)Press the lever briefly in direction 3:
The vehicle accelerates to and main-
tains the last speed stored.To deactivatePress the lever briefly in direction 4:
The cruise control is deactivated imme-
diately.
In addition, the system is also automati-
cally deactivated in response to the
following conditions:
>When you apply the brakes
>When you depress the clutch or move
the automatic transmission selector
lever from "D" to "N"
>If you exceed or fall below the preset
speed for an extended period (by
depressing the accelerator, for
example).

ASC+T Dynamic Stability Control (DSC)*Reactivate the ASC+TPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T. It will
always be the driver's responsibility to
drive in a manner that matches road
conditions. We therefore urge you to
avoid using the additional safety margin
of the system as an excuse for taking
risks.<
For additional details concerning
ASC+T, please refer to the chapter,
"Advanced technology," page 165.
The conceptDSC maintains vehicle stability, even in
critical driving situations.
The system optimizes vehicle stability
during acceleration and when starting
from a full stop, as well as optimizing
traction. In addition, it recognizes
unstable vehicle conditions, such as
understeering or oversteering, and, as
far as is possible within the laws of
physics, helps keep the vehicle on a
steady course by reducing the engine
speed and brake applications to the
individual wheels.
The DSC is operational every time you
start the engine. DSC includes the
functions of ADB and CBC, refer to
page 102.
The ADB (Automatic Differential
Braking) copies the function of conven-
tional differential and transverse locks
through brake intervention, and
increases traction whenever conditions
merit, e. g. when driving on snow-
covered roads.
If the DSC is deactivated the ADB is in
ready mode.
Indicator lamp
