Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent 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

●

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

<

Engine oil pressure

●

An alarm sounds at the same
time. Stop vehicle immediately
and switch off engine. Check the
engine oil level and top up as required.
If the oil level is correct, please contact
the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

Flat Tire Monitor

●

In addition, an acoustic signal is
sounded: a tire failure has
occurred. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.

30Opening and closing
KeysThe key set1Master keys with remote control
unit – determine the functions of the
Key Memory, refer to page 59.
You can mark the individual keys for
subsequent identification by apply-
ing the colored decals that you
received when accepting delivery of
your vehicle
There is an extended-life battery
in every master key with remote
control that is charged automatically in
the ignition lock as you drive.
For this reason, if you have a master
key that is otherwise not used, use that
key at least once every year while driv-
ing for an extended period to charge
the battery.<
2Spare master key – for storage in a
safe place, such as in your wallet.
This key is not intended for constant
use
3Door and ignition key – the locks for
the luggage compartment lid and the
glove compartment cannot be oper-
ated with this key. This is useful for
valet parking, for example
Central locking systemThe conceptThe central locking system engages
and releases the locks on the
>doors
>luggage compartment lid
>fuel filler door.
The central locking system is ready for
operation whenever the driver's door is
closed.
The central locking system can be
operated
>from outside via the door lock and
using the remote control
>from inside via the central locking
system button.
If it is operated from inside, the fuel
filler door will not be locked, refer to
page 34.
When the system is actuated from the
outside, the anti-theft system is also
activated. This prevents the doors from
being unlocked via the lock buttons or
the release handle. The alarm system is
also armed or disarmed.
If locked from inside, the central locking
system unlocks the vehicle automati-
cally in the event of an accident. In
addition, the hazard warning flashers
and interior lamps come on.

Opening and closing – via the remote controlThe conceptThe remote control gives you an excep-
tionally convenient method for unlock-
ing and locking your vehicle. Further-
more, it provides two additional
functions:
>Switch on the interior lamps, refer to
page 32.
With this function you can also
search for your vehicle – when
parked in an underground garage, for
instance
>Open the luggage compartment lid,
refer to page 32.
The luggage compartment lid will
open slightly, regardless of whether it
was locked or unlocked.
The anti-theft system is also deacti-
vated/activated simultaneously with the
unlocking or locking of the vehicle, and
the alarm system is disarmed/armed,
and the interior lamps are switched
on/off.
You can have a signal set to con-
firm that the vehicle's locks have
engaged securely.<
Master keys with remote control
Since passengers or animals
remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle's keys with you
so that the vehicle can be opened again
from the outside at any time.<
If it is no longer possible to lock
the vehicle via the remote control,
the battery is discharged. Use this key
while driving for an extended period in
order to recharge the battery. Guard
the remote control against unauthorized
use by only surrendering the spare key
or the door and ignition key, e.g. for
valet parking.
In the event of a system malfunction,
please contact your BMW center. You
can also obtain replacement keys
there.<

vehicle entry and attempted theft by
simultaneously activating the following:
>Sounding an acoustical alarm for
30 seconds
>Activating the hazard warning flash-
ers for approx. five minutes
>Flashing the high beams on and off in
rhythm with the hazard warning flash-
ers.To arm and disarm the alarm

124Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust, some of its con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after
handling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
OBD interface socketThe 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
assure proper emission-control system
operation for the vehicle's lifetime by
monitoring emission-related compo-
nents and systems for deterioration and
malfunction.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
earliest possible opportunity.

Lamps and bulbsThe lamps and bulbs make essential
contributions to the safety of your vehi-
cle. Therefore, comply fully with the fol-
lowing instructions during bulb replace-
ment. If you are not familiar with any of
the procedures, consult your BMW
center.
Do not touch the glass portion of
a new bulb with your bare hands
since even small amounts of impurities
burn in to the surface and reduce the
service life of the bulb. Use a clean
cloth, paper napkin, or a similar mate-
rial, or hold the bulb by its metallic
base.<
A replacement bulb set is available from
your BMW center.
Before working on the electrical
system, switch off the electrical
accessory you are working on or dis-
connect the cable from the negative
terminal of the battery. Failure to
observe this precaution could result in
short circuits.
To prevent injuries and damage when
changing a bulb, be sure to comply with
any instructions provided by the bulb
manufacturer.<
Low beams and high beams>Low beams: H7 bulb, 55 watts
>High beams: H7 bulb, 55 watts.
The H7 bulb is pressurized. There-
fore, wear safety glasses and pro-
tective gloves. Failure to comply with
this precaution could lead to injury if the
bulb is damaged.<
Please contact a BMW center in case of
a malfunction.
When cleaning the headlamps, please
follow the instructions in the Caring for
your vehicle brochure.Parking lamps5 watt bulb
Please contact a BMW center in case of
a malfunction.Xenon lamps*The service life of these bulbs is very
long and the probability of a failure is
very low, provided that they are not
switched on and off an unusual number
of times. If one of these bulbs should
nevertheless fail, it is possible to con-
tinue driving with great caution using
the fog lamps, provided traffic laws in
your area do not prohibit this.
Because of the extremely high
voltages involved, any work on the
xenon lighting system, including bulb-
changing, should be carried out by
technically-qualified personnel only.
Otherwise, there is a risk of fatal
injury.<

You will find corresponding
instructions for using the
M Mobility system on the device.
Replace the defective tire as soon as
possible and have the new wheel bal-
anced. Reinitialize the Flat Tire Monitor,
and refer to page 83 for further informa-
tion. Have the M Mobility system
refilled. Contact your BMW center for
this.<
Protect valve stems against dirt using
screw-on dust caps. Dirty valve stems
frequently lead to slow pressure loss.
Battery
Battery posts, terminals, and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
MaintenanceThe battery is completely maintenance-
free. That means that the original bat-
tery acid will normally last for the ser-
vice life of the battery under moderate
climate conditions.
Please consult your BMW center
whenever you have any questions
concerning the battery. Since the bat-
tery is absolutely maintenance-free, the
following statements are for your infor-
mation only.<
Never disconnect the battery
when the engine is running; the
ensuing voltage surge would seriously
damage the vehicle's onboard elec-
tronic systems. when the engine is not running. Use the
connections provided in the engine
compartment. For information on the
connections, see Jump-Starting,
page 139.
Return used batteries to a recy-
cling point or your BMW center.
Maintain the battery in an upright posi-
tion for transport and storage. Secure
the battery against tilting in transit.<
