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 in the
following section.

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 and 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:
check the brake fluid level. Before driv-
ing further, be sure to comply with the
instructions on pages 116 and 129.
Parking brake warning lamp for
Canadian models.
Tire Pressure Monitor (TPM)/Flat
Tire Monitor

●

In addition, an acoustic signal is
sounded: a tire failure has occurred.
Reduce vehicle speed immediately and
stop the vehicle. Avoid hard brake
applications. As you steer the vehicle,
use caution and avoid overcorrecting.
For additional information: refer to
pages 85, 86

Red and yellow: continue driving
cautiously

The brake warning lamp comes
on together with the yellow indi-
cator lamps for ABS

●
and
ASC+T/DSC:
The entire ABS, CBC,
ASC+T/DSC and
ADB/ADB-X/DBC control sys-
tem has failed. Continue driving
cautiously and defensively. Avoid full
brake applications. Please have the
system checked by your BMW center
as soon as possible.

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:
1. Undo the trim panel on the right side
of the cargo area
2. Pull the knob with the fuel pump
symbol.
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 filler cap carefully to
prevent fuel from spraying out.
Fuel spray may cause injury.<
Put the filler cap in the bracket – see
arrow – attached to the fuel filler door.
When refueling, insert the filler nozzle
completely into the filler pipe. Pulling
the nozzle out of the pipe during refuel-
ing
>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 fuel filler 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 FILLER CAP
lamp.<
Fuel 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 pressureThe specified inflation pressures are
provided on a sticker attached to the
B-pillar and are visible with the driver's
door open.Checking tire pressuresAll pressures are specified in the stan-
dard units of pressure, psi and kilopas-
cal, and apply to cold tires – tires at
ambient temperature – refer to tire
pressure table at the end of this chap-
ter.
Vehicles with Tire Pressure Monitor
(TPM)/Flat Tire Monitor:
After correcting the inflation pressures,
reinitialize the system. Refer to
pages 85, 86.

3Starting the 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
you hear the lock engage.
If the key is not removed, an acoustic
signal is sounded after the driver's door
has been opened.
The sound system remains operational
for approx. 20 minutes after you switch
off the ignition – ignition key in position
0 or key removed. Simply switch it back
on.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 engineBefore starting>Engage the parking brake
>Ensure that the gearshift lever is in
neutral, or, with an automatic trans-
mission, that the selector lever is in
Park
>Depress the clutch pedal.
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,
and parking the vehicle, take care
to avoid contact between the hot
exhaust system and flammable materi-
als – grass, hay, leaves, etc. Such con-
tact 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.
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.<
If the engine does not 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 extremely cold tempera-
tures below approx. +57/ –156 at
high altitude over 3,300 ft/1,000 m:
>On the first start attempt, it may be
necessary to engage the starter for a
longer period, but no longer than
20 seconds
>Press the accelerator pedal halfway
down while engaging the starter.
The engine's idle speed is controlled by
the engine-management system. A high
idle after starting is normal and should
decrease as the engine warms up. If the
idle speed does not decrease, service
is required.
To prevent the battery from discharg-
ing, always switch off electrical devices
which are not in use and the ignition
when the vehicle is not being driven.
Extended starting attempts, char-
acterized by excessively frequent
or long periods with the starter
engaged, can damage the catalytic
converter.<
