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.<
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. Otherwise, incorrect tire pres-
sure can lead to poor handling, to tire
damage and accidents.
Remember to check the inflation pres-
sure in the space-saver or standard
spare tire.
Inflate the spare tire to the highest infla-
tion pressure specified for your vehi-
cle.
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.Tire inflation pressure

Tire Pressure Monitor (TPM)*The conceptTPM monitors the tire pressures at all
four tires even while the vehicle is mov-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly 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,
TPM sets the current inflation pres-
sures in the tires as the target values
to be monitored.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
valid. Please check the inflation pres-
sure again and make corrections
according to the inflation pressure
table. Then reinitialize the system.

panied by an acoustic warning signal.

Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after adjusting the
inflation pressure and letting the system
"learn" the correct pressures.
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 the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes' driving time, the
Flat Tire Monitor adopts the current
pressure levels as the reference, and
from that point on, can detect and
report a flat tire.
To activate/deactivate the systemThe Flat Tire Monitor automatically
assumes operation whenever you turn
the ignition key to position 2. Unless
manually deactivated, it is always on
during normal vehicle operation.
To deactivate the system: press the
button, the yellow indicator lamp comes
on.
To activate the system: press the but-
ton again, the indicator lamp goes out.
You should deactivate the system
before driving with snow chains, as the
chains can generate spurious warnings
and/or prevent the system from detect-
ing actual pressure loss.

Flat tire
The red warning lamp in the
instrument cluster lights up to
warn of pressure loss and tire
failure. This visual alert is accompanied
by an acoustic warning signal. Reduce
your speed immediately, and steer and
brake gently as you bring the vehicle to
a stop.
To reset the warning lamp: after replac-
ing the damaged tire you will need to
reset the red warning lamp manually:
maintain pressure on the Flat Tire Moni-
tor button until the warning lamp goes
out. Then reinitialize the system.
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors.
The system also does not detect the
gradual and minor loss of pressure that
all tires display over extended periods
of time.<
Check tire inflation pressures on a
regular basis, correcting them as
necessary; refer to page 25.
The system may respond to operation
on slippery or snow-covered road sur-
faces with false warnings or delays in
detecting actual pressure loss.
Performance-oriented driving – slip at
the drive wheels, high rates of lateral
acceleration – can also increase the
time that the Flat Tire Monitor requires
to detect a flat.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on
until the problem is corrected.
Please refer the problem to your BMW
center.

117 Wheels and tires
Tire inflation pressureInformation for your safetyThe factory-approved tires are matched
to your vehicle and have been selected
to provide optimum safety and driving
comfort when used properly.
It is not merely the tire's service life, but
also driving comfort and – above all else
– driving safety that depend on the con-
dition of the tires and the maintenance
of the specified tire inflation pressure.
Incorrect tire inflation pressure is a fre-
quent cause of tire damage. Tire pres-
sure also has a major effect on your
BMW's handling response.
Be sure to check the tire inflation
pressure, including the pressure
of the space-saver spare tire or the
spare tire, on a regular basis, at least
twice a month and before every
extended journey, refer to page 25.
Otherwise, incorrect tire pressure can
lead to poor handling, to tire damage
and accidents.<
Tire conditionTire tread – tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 1/8 in / 3 mm, even though
the legally specified minimum tread
depth is 1/16 in / 1.6 mm.
Below 1/8 in / 3 mm tread depth, there
is a great risk of hydroplaning, even at
relatively moderate speeds and with
only small amounts of water on the
road. Tread wear indicators in the
tread-groove base – see arrow – are
distributed around the wheel circumfer-
ence and are labeled on the tire side-
wall with TWI – Tread Wear Indicator. At
a tread depth of 1/16 in / 1.6 mm, the
indicators signal that the legally permis-
sible wear limit has been reached.
Do not drive on a deflated – flat –
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle. Avoid overloading the vehi-
cle so that the permitted load on the
tires is not exceeded. Overloading can
lead to overheating and internal tire
damage.
The ultimate result can assume the
form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation can indicate a
flat tire or some other vehicle malfunc-
tion. This type of problem can be
caused by contact with curbs, etc. This
is also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed. Pro-
