Overview

Fuel specifications Tire inflation pressuresThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
The inflation pressures are indicated on
a label attached to the B-pillar behind
the driver's door (visible with door
open).Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal [kPa]) with the tires at
ambient temperature (refer also to the
next page).
Check tire inflation pressures
regularly Ð at least every two
weeks and before every extended
journey. Incorrect tire pressure can
otherwise lead to tire damage and acci-
dents.
Check the inflation pressure of the
spare tire as well. Refer to the following
table and to page 110.<367de388
Comply with tire approval
specificationsThe inflation pressures in the table apply
to tires made by BMW-approved manu-
facturers. Your BMW center is familiar
with these pressures. Higher pressures
may be specified for tires made by other
manufacturers. You will find a list of
approved tires beginning on page 116.
Your vehicle is equipped with tires that
meet both US standards and European
standards. We recommend the exclu-
sive use of BMW-approved tires.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
In a very real sense, both tire life and
your own safety are riding on correct
tire specifications and inflation pres-
sures, refer to page 26.
Incorrect tire inflation pressure is
a frequent cause of tire damage. It
also significantly influences the road-
holding ability of your BMW. Be sure to
check the tire inflation pressures,
including the spare tire, on a regular
basis, at least twice a month and before
doing any extended driving, refer to
page 26. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately
resulting in accidents.<
Check the inflation pressure of
the spare tire For checking tire pressures, there is a
valve extension (arrow) on the storage
tray of the spare wheel which is acces-
sible from outside.367de309
Tire tread Ð tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is 0.063 in (1.6 mm). Tread wear
indicators (arrow) are embedded in the
base of the tire's tread. Their locations
are indicated by the legend TWI Ð Tread
Wear Indicator Ð at various points on
the tire's shoulder. When the tread
reaches a depth of 0.063 in (1.6 mm),
these indicators appear to signal that
the tires have worn to the minimum
legal level. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively 390de331

Special features of winter tires Snow chains
*
Choosing the right tireBMW recommends winter tires (M+S
radial tires) for operation under
inclement winter driving conditions.
While so-called all season tires (M+S
designation) provide better winter trac-
tion than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally do not achieve the performance of
winter tires.
In the interests of sure tracking and safe
steering response, mount winter tires
which are made by the same manufac-
turer and which have the same tread
configuration at all four wheels.Comply with recommended speed
Never exceed the maximum
speed for which the winter tires
are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Any BMW center
has the required technical knowledge
and the proper equipment and will be
happy to assist you.<
Tire condition, tire pressureOnce the tire wears to below 0.16 in
(4 mm), winter tires display a percep-
tible decrease in their ability to cope
with winter driving conditions, and
should be replaced in the interest of
safety.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.BMW narrow-link snow chains are
intended for mounting in pairs at the
rear wheels only. Comply with all manu-
facturer's safety precautions when
mounting the chains. Do not exceed a
speed of 30 mph (50 km/h) while
driving with mounted snow chains.
