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. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. 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

●

Stop the vehicle immediately
and switch off the engine.
Check the engine oil level; top off as
required. If the oil level is correct:
please contact the nearest BMW cen-
ter.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

<

Brake warning lamp

●

If the lamp comes on when the
parking brake is not engaged:

RefuelingFuel filler door
Always switch off the engine
before refueling, as it is not possi-
ble to add fuel with the engine running,
and attempts may also trigger the
SERVICE ENGINE SOON lamp.<
Press on the rear edge of the fuel filler
door to open and close it.
If an electrical malfunction occurs, you
can unlock the fuel filler door manually:
Pull the knob with the fuel pump sym-
bol, located on the right side wall of the
luggage compartment.
Always observe all safety precau-
tions posted at the service station
when handling fuel.
Never carry spare fuel containers in
your vehicle. Whether empty or full,
these containers can leak, cause an
explosion, or lead to fire in the event of
a collision.<
Simple and environmentally
friendly
Open the gas cap carefully to pre-
vent fuel from spraying out. Fuel
spray may cause injury.<
Keep the gas cap in the bracket
attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Lifting the
nozzle during refueling
>results in premature pump shutoff
>and will reduce the effectiveness of
the vapor recovery system on the
pump.
The fuel tank is full when the filler noz-
zle shuts off the first time.

25
Close the gas cap carefully after
refueling until a click is heard.
While closing, be sure not to squeeze
the strap which is fastened to the cap.
A loose or missing cap will activate the
CHECK GAS CAP* lamp.<
Tank capacity>Approx. 16.6 gal./63 liters, of which
>approx. 2.1 gal./8 liters are reserve
capacity.
Do not drive to the last drop of
fuel. This can prevent the engine
from operating properly and result in
damage.<
Fuel specificationsThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Never use leaded fuel, as it would
cause permanent and irreversible
damage to the oxygen sensor and the
catalytic converter.<
Tire inflation pressureChecking tire pressuresTire pressures in psi/kilopascal are
shown on the driver's door post and are
visible when the door is open.
Only check the tire inflation pressures
of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
In the following tire inflation pressure
table, all pressures are specified in the
standard units of pressure, psi and kilo-
pascal, and apply to cold tires, i.e. tires
at ambient temperature.

Vehicle Memory, Key MemoryHow the system functionsNo doubt you have reflected at one
time or another on how great it would
be if you could permanently configure
your vehicle's various features and
adjustments to mirror your own individ-
ual preferences. In engineering your
vehicle, BMW has provided for a num-
ber of options for personal adjustment
that can be programmed into your vehi-
cle at your BMW center.
The available configuration data fall into
two categories, according to whether
their primary orientation is the vehicle –
Vehicle Memory – or the individual –
Key Memory. Provided that each per-
son has a separate remote-control key,
you can have your BMW center enter
basic adjustment data for up to four
individuals in the system.
The system then relies on a bilateral
data exchange to identify the individual
user and executes the selected settings
whenever the remote control unit is
used to disengage the door locks.
Distinguishing between keysColor-coded decals have been pro-
vided to help you distinguish individual
keys with different settings.What the system can doYou can learn about the entire array of
features this system offers at your BMW
center.
You will see this symbol through-
out the Owner's Manual. It is to
remind you at appropriate places of the
settings that are available to you.<
Examples for Vehicle Memory:
>Various signals as acknowledgment
when locking or unlocking your vehi-
cle, refer to pages 33, 36
>Activating/deactivating the 'Follow
me home' function, refer to page 94
>Activating/deactivating daytime driv-
ing lamps, refer to page 94
>Selecting units of measure for dis-
playing time, outside temperature,
distance traveled and fuel consump-
tion in the instrument panel
>When you shift into Reverse, an
acoustic signal indicates that PDC
has been activated, refer to page 86
>Switching on the rear window
defroster automatically, refer to
pages 100, 105
>Activates/deactivates various alarm
system functions, refer to page 42
>Having the onboard computer display
– after giving an ice warning – return to
its previous setting, refer to page 84.
Examples for Key Memory:
>Unlocking the driver's door first, then
the vehicle's remaining locks, refer to
page 33
>Locking the vehicle after pulling
away, refer to page 37
>Automatically repositioning of the
driver's seat for the corresponding
driver when the vehicle is unlocked,
refer to page 53
>Automatic tilting of the passenger-
side mirror, refer to Automatic curb
monitor, page 54.

3Starting engine
Vehicles with automatic transmis-
sion:
Do not move the selector lever from
position P until the engine is running,
ignition key position 2.
Your vehicle is equipped with an inter-
lock. Therefore, the ignition key cannot
be turned to position 0 or removed until
the selector lever is in position P.<
Vehicles with manual transmis-
sion:
Step on the clutch when starting the
vehicle. A lockout prevents the engine
from starting if the clutch is not
depressed.<
Steering lockedThe key can only be inserted and
removed in this position.
After removing the key, turn the steer-
ing wheel slightly to the left or right until
the lock engages.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.Steering unlockedYou will find that it is often easier to turn
the ignition key from position 0 to posi-
tion 1 when you move the steering
wheel slightly to help disengage the
lock.
Individual electrical accessories are
ready for operation.
Starting the engine
Do not allow the engine to warm
up by leaving it running while the
vehicle remains stationary. Instead,
drive off immediately at a moderate
engine speed.<
Do not allow the engine to run in
enclosed spaces. Otherwise,
breathing the exhaust fumes can lead
to unconsciousness and death. The
exhaust gases contain carbon monox-
ide, an odorless and colorless, but
highly toxic gas. Do not leave the vehi-
cle unattended with the engine running.
An unattended vehicle with a running
engine represents a safety hazard.
When driving, standing at idle or park-
ing the vehicle, take care to avoid con-
tact between the hot exhaust system
and flammable materials – grass, hay,
leaves, etc. Such contact could lead to
a fire, resulting in serious personal
injury and property damage.<
Start the engine. Do not press the
accelerator pedal.
Do not actuate the starter for too
short a time, but do not actuate it
for more than approx. 20 seconds.
Release the ignition key immediately
when the engine starts.<
