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.

Vehicles with Flat Tire Monitor:
After correcting the inflation pressures,
reinitialize the system. Refer to
page 92.
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
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. 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. Other 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.

Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
The system actually detects pressure
loss by monitoring differences in the
relative speeds of the four wheels. It
interprets variations outside specified
limits as severe pressure loss, and then
responds by generating a warning.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table on page 26 and cor-
rect them, if necessary
3. Initialize the system.
System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to until the yellow indicator lamp in
the instrument cluster lights up for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.

124Wheels 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 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. If this is not done,
incorrect tire pressures can cause driv-
ing instability and tire damage, ulti-
mately resulting in 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.
