Refueling
Always switch off the engine before refu-
eling, otherwise no fuel can be filled into
the tank and a message is displayed.<
When handling fuel, always observe all
applicable precautionary measures and
regulations. Never transport reserve fuel con-
tainers in the vehicle. These could become
leaky and cause an explosion or a fire in an acci-
dent.<

Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pressure are crucial not only
to the tire's service life, but also to driving com-
fort and most importantly, driving safety.
Checking pressure
Only check tire inflation pressure when the tires
are cold. This means after a maximum of
1.25 miles/2 km driving or when the vehicle has
been parked for at least 2 hours. When tires are
warm, the tire inflation pressure increases.
Check the tire inflation pressure regularly
and correct it as needed, even on the
compact tire
*: at least twice a month and before
starting long trips. Otherwise driving instability
or tire damage, and therefore accidents, can
result from incorrect tire inflation pressures.
Do not drive with depressurized, i.e. flat tires,
except run-flat tires. A flat tire will seriously
impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page90, or reset the Tire Pressure Monitor,
refer to page92.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW center. tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. 100 mph/
160 km/h to achieve optimum driving comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages. Oth-
erwise tire damage and accidents could
occur.<
Observe all national and local maximum speed
limits, otherwise violations of the law could
occur.

Tire age
The manufacturing date of tires is contained in
the tire coding: DOT... 0806 indicates that the
tire was manufactured in week 8 of 2006.
BMW recommends that you replace all tires
after 6 years at most, even if some tires may last
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable
on the tire sidewall between tread shoulder and
maximum section width. For example:
Tread wear 200 Traction AA
Temperature A
DOT Quality Grades
Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to
Federal Safety Requirements in addition
to these grades.<
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire graded
150 would wear one and one-half (1γ) times as
well on the government course as a tire graded
100. The relative performance of tires depends
upon the actual conditions of their use, how-
ever, and may depart significantly from the
norm due to variations in driving habits, service
practices and differences in road characteris-
tics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, B, and C.
Those grades represent the tire's ability to stop
on wet pavement as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance.The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
Temperature
The temperature grades are A, the highest, B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page201.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
XL
Indicates specially reinforced tires.
