Indicator and warning lamps

Technology that monitors itself

Many of the systems of your BMW
monitor themselves automatically, both
during engine starts and while you are
driving. Indicator and warning lamps
that are identified by "

l

" are tested for
proper functioning whenever the igni-
tion 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 below.

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, do not
continue driving. The engine could
be damaged due to overheating.
Increased force is required to steer the
vehicle if the drive belt is defective.

<


Engine oil pressure

l

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level. Top up as
required. If oil level is correct: please
contact the nearest BMW center.
Do not continue driving, other-
wise, the engine could be
damaged because of inadequate lubri-
cation.

<



Brake hydraulic system

l

The brake fluid level is too low.
Before driving further, be sure to
read the notes on pages 92 and 112.

Replacement keysReplacement keys are available exclu-
sively through your BMW center. Your
BMW center is obligated to ensure that
a person requesting a key is authorized
to do so since the keys belong to a
security system (refer to "Electronic
vehicle immobilizer" on the next page).
If possible, take all of the master
keys that belong to the vehicle
with you when you pick up your
replacement key.
Whenever you receive a new
replacement key, turn that key to posi-
tion 2 in the ignition lock once (ignition
switched on) and then back. This allows
the electronic vehicle immobilizer to
"learn" the new key.<

Starting the engineBefore starting>Engage the parking brake.
>Put manual-shift gear lever in idling
position.
>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 engineStart the engine. Do not press the
accelerator pedal.
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
allowing it to run while the vehicle
remains stationary. Instead, begin
driving 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 (–15 6) and at
altitudes above approx. 3,300 ft
(1,000 meters):
>On the first start attempt, engage the
starter for a longer period (approx.
10 seconds).
>Press the accelerator pedal halfway
down while engaging the starter.
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.

MaintenanceThe battery is completely maintenance-
free. That means that the original elec-
trolyte will normally last for the service
life of the battery under moderate
climatic conditions.SymbolsYou will find the following symbols on
your vehicle battery. To avoid injury,
please comply with the corresponding
precautions whenever you work with or
near the battery.
Please read the following infor-
mation before working with the
battery.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
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.
Ensure that children keep well
away from batteries and battery
acid.
Do not allow sparks or open
flame near the battery. Do not
smoke near the battery. Avoid
sparks from electrical cables or elec-
trical equipment. Turn the key to posi-
tion 0 in the ignition lock when the
battery is disconnected or connected.
Do not short circuit the battery termi-
nals. This creates a risk of personal
injury from high-voltage sparks.
A highly-explosive gas is gener-
ated when the battery is charged.
If acid is accidentally splashed
into your eyes, rinse them thor-
oughly for 15 minutes with clear
water. Following that, consult a physi-
cian immediately. If acid splashes onto
your skin or clothing, rinse immediately
with ample clean water. If acid is acci-
dentally swallowed, consult a physi-
cian immediately.
In order to protect the battery
case from ultraviolet radiation,
do not place it in direct sunlight.
A discharged battery can freeze. Store
the battery in areas where temperature
remains above freezing.
