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.

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.

Another instruction plate regarding
inflation pressures on the door pillar
indicates which system your vehicle is
equipped with.
Check the tire pressures on a reg-
ular basis – at least twice a month
– and before every extended journey. If
this is not done, incorrect tire pressures
can cause driving instability and tire
damage, ultimately resulting in an acci-
dent.
Remember to check the inflation pres-
sure in the space-saver or standard
spare tire, refer to page 141.
Inflate the spare tire to the highest infla-
tion pressure specified for your vehi-
cle. specificationsThe inflation pressures in the table
apply to BMW approved tire sizes and
tire manufacturers. Your BMW center
can provide you with more information
about these. Higher pressures may be
required for tires made by other manu-
facturers.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW approved
tires.

Adjusting safety belt heightUse the height adjustment mechanism
to adapt the shoulder strap to the ideal
level for your own body:
>Slide the button up or down.
Please refer to the seat adjustment
instructions on page 43.
If the safety belt system has been
subjected to the stresses involved
in an accident or otherwise damaged:
Have the entire safety belt mechanism
replaced by your BMW center, includ-
ing the safety belt tensioner. In addi-
tion, have your BMW center inspect the
safety belt anchors. If a child-restraint
system was in the vehicle during an
accident, consult the manufacturer's
instructions regarding replacement.<
Seat and mirror memory*You can store as many as three differ-
ent driver's seat and mirror adjustment
settings into the system for later selec-
tion.
Memory will not retain the adjust-
ment made to the lumbar sup-
port. 2. Adjust the seat and door mirrors to
the desired position
3. Press the MEMORY button: indica-
tor lamp in the button comes on
4. Press memory button 1, 2 or 3, as
desired: indicator lamp goes out.
To select a stored setting
Do not select a memory position
while the vehicle is moving. If you
do so, there is a risk of accident from
unexpected seat movement.<
Ignition key in position 1:
>Briefly press memory button 1, 2 or 3,
as desired. Movement stops immedi-
ately when one of the seat-adjust-
ment or memory buttons is activated

Tire Pressure Monitor (TPM)*The conceptTPM monitors the tire pressures at all
four tires while the vehicle is moving.
The system provides an alert whenever
the inflation pressure drops significantly
below the specified pressure in one or
more tires.
This indicator lamp in the instru-
ment cluster informs you when
the tire pressure deviates from
the target values.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sures.
Repeat this process after tire replace-
ment, tire rotation or any changes in tire
inflation pressure.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25
and adjusting their pressure if neces-
sary.
2. Turn ignition key to position 2 – do
not start the engine
3. Press the button long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few sec-
onds
4. After a few minutes' driving time, the
TPM adopts the current pressure lev-
els as the reference, and from that
point on, can detect and report a flat
tire.In the event of loss in inflation
pressureIf the inflation pressure has dropped
significantly over a long period of time,
which is normal for any tire, the yellow
indicator lamp will come on.
This alerts you to have the tires inflated
to the specified pressures as soon as
possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. Then reinitialize the system. sure, the indicator lamp comes on with
a red lamp. This visual alert is accom-
panied by an acoustic warning signal.
