CAUTION
The use of poor-quality fuels may result in
harmful engine deposits or damage. Additionj
ally, problems relating to drivability, starting and stalling, especially under certain environmentalconditions such as high ambient temperature
and high altitude, may occur.
If drivability problems are encountered, we recj
ommend switching to a high quality gasoline
brand and a higher octane grade n AKI numj
ber n for a few tank fills. To avoid harmful enj
gine deposits, it is highly recommended to purj
chase gasoline from Top Tier retailers.
Failure to comply with these recommendations
may result in the need for unscheduled maintej
nance.
Recommendedfuelgrade
BMW recommends AKI 93.
Minimumfuelgrade
BMW recommends AKI 91.
If you use gasoline with this minimum AKI Rating,
the engine may produce knocking sounds when
starting at high external temperatures. This has
no effect on the engine life.

Tireinflationpressure
Generalinformation The tire inflation pressure and tire characteristics
influence the following:
'xThe service life of the tires.'xRoad safety.'xDriving comfort.'xDriving dynamics.'xFuel consumption.
Safetyinformation
WARNING
A tire with too little or no tire inflation pressure
may heat up significantly and sustain damage.
This will have a negative impact on aspects of handling, such as steering and braking rej
sponse. There is a risk of an accident. Regularly
check the tire inflation pressure, and correct it as needed, for instance twice a month and bej
fore a long trip.
Tireinflationpressure

Inthetireinflationpressuretable The tire inflation pressure table, refer to
page 213, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pressure
values apply to tire sizes approved by the manuj
facturer of the vehicle for the vehicle type.
To identify the correct tire inflation pressure,
please note the following:'xTire sizes of your vehicle.'xMaximum permitted driving speed.

DOTQualityGrades
Treadwear
Traction AA A B C
Temperature A B C
All passenger vehicle tires must conform to Fedj
eral Safety Requirements in addition to these grades.
Treadwear The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified govj
ernment test course. E.g., a tire graded 150
would wear one and one-half, 1 g, 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, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics 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 surfaj
ces 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, cornering, hydroj planing, or peak traction characteristics.
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 excesj
sive temperature can lead to sudden tire failure.The grade C corresponds to a level of performj
ance which all passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represent higher levels of performance on the laboratory test wheel than
the minimum required by law.
WARNING
The temperature grade for this tire is estabj lished for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in comj bination, can cause heat buildup and possibletire failure.
M+S
Winter and all-season tires with better cold
weather performance than summer tires.
Tiretread
Summertires Do not drive with a tire tread of less than
0.12 in/3 mm, otherwise there is an increased
risk of hydroplaning.
Wintertires
Do not drive with a tire tread of less than
0.16 in/4 mm, as such tires are less suitable for
winter operation.

Page 216 of 276

Minimumtreaddepth
Wear indicators are distributed around the tire's
circumference and have the legally required minj imum height of 0.063 inches/1.6 mm.
The positions of the wear indicators are marked on the tire sidewall with TWI, Tread Wear Indicaj
tor.
Tiredamage
Generalinformation Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Driving over rough or damaged road surfaces, as
well as debris, curbs and other obstacles can
cause serious damage to wheels, tires and susj
pension parts. This is more likely to occur with
low-profile tires, which provide less cushioning
between the wheel and the road. Be careful to
avoid road hazards and reduce your speed, esj
pecially if your vehicle is equipped with low-proj file tires.
Indications of tire damage or other vehicle malj
functions:
'xUnusual vibrations.'xUnusual tire or running noises.'xUnusual handling such as a strong tendency
to pull to the left or right.
Damage can be caused by the following situaj
tions, for instance:
'xDriving over curbs.'xRoad damage.'xTire inflation pressure too low.'xVehicle overloading.'xIncorrect tire storage.
Safetyinformation
WARNING
Damaged tires can lose tire inflation pressure,
which can lead to loss of vehicle control. There is a risk of an accident. If tire damage is susj
pected while driving, immediately reduce speed
and stop. Have wheels and tires checked. For
this purpose, drive carefully to the nearest dealj erss service center or another qualified service
center or repair shop. Have vehicle towed or
transported as needed. Do not repair damaged
tires, but have them replaced.
WARNING
Tires can become damaged by driving over obj
stacles, e.g., curbs or road damage, at high
speed. Larger wheels have a smaller tire cross- section. The smaller the tire cross-section, the
higher the risk of tire damage. There is a danj
ger of accidents and property damage. If possij
ble, drive around obstacles, or drive over them
slowly and carefully.
Changingwheelsandtires
Mounting
Have mounting and wheel balancing carried out
by a dealerss service center or another qualified
service center or repair shop.

about the correct wheel/tire combination andwheel rim versions for the vehicle.
Safetyinformation
WARNING
Wheels and tires which are not suitable for your
vehicle can damage parts of the vehicle, for inj stance due to contact with the body due to tolj
erances despite the same official size rating.
There is a risk of an accident. The manufacj turer of your vehicle strongly suggests that you
use wheels and tires that have been recomj mended by the vehicle manufacturer for your
vehicle type.
WARNING
Incorrect wheel/tire combinations will have a negative impact on the vehicle's handling and
on the function of a variety of systems, such as
ABS or DSC. There is a risk of an accident. To
maintain good handling and vehicle response, use only tires with a single tread configuration
from a single manufacturer. The manufacturer
of the vehicle recommends that you use
wheels and tires that have been recommended
by the vehicle manufacturer for your vehicle type. Following tire damage, have the original
wheel/tire combination remounted on the vehij
cle as soon as possible.
Recommendedtirebrands
For each tire size, the manufacturer of the vehij cle recommends certain tire brands. The tire
brands can be identified by a star on the tire
sidewall.
Newtires Tire traction is not optimal due to manufacturing
circumstances when tires are brand-new; they achieve their full traction potential after a break-intime.
Drive conservatively for the first
200 miles/300 km.
Retreadedtires
WARNING
Retreaded tires can have different tire casing
structures. With advanced age the service life
can be limited. There is a risk of an accident.
The manufacturer of your vehicle does not recj
ommend the use of retreaded tires.
The manufacturer of your vehicle does not recj
ommend the use of retreaded tires.
Wintertires Winter tires are recommended for operating on
winter roads.
Although so-called all-season M+S tires provide better winter traction than summer tires, they
usually do not provide the same level of performj ance as winter tires.

Maximumspeedofwintertires
If the maximum speed of the vehicle is higher
than the permissible speed for the winter tires,
then attach a label showing the permissible maxij mum speed in the field of view. The label is availjable from a dealerss service center or anotherqualified service center or repair shop.
With winter tires mounted, observe and do not
exceed the permissible maximum speed.
Rotatingwheelsbetweenaxles
The manufacturer of your vehicle advises against
switching wheels between the front and rear axles. This can impair the handling characterisjtics.
Rotating the tires between the axes is not perj
missible on vehicles with different tire sizes or rim sizes on the front and rear axles.
Storingtires
Airpressure
Do not exceed the maximum tire inflation presj
sure indicated on the side wall of the tire.
Storage Store wheels and tires in a cool, dry and dark
place.
Always protect tires against all contact with oil,
grease, and solvents.
Do not leave tires in plastic bags.
Remove dirt from wheels or tires.

MobilitySystem
Concept
With the Mobility System, minor tire damage can be sealed temporarily to enable continued travel.To accomplish this, sealant is pumped into thetires, which seals the damage from the inside.
Generalinformation
'xFollow the instructions on using the Mobility
System found on the compressor and sealant container.'xUse of the Mobility System may be ineffecj
tive if the tire puncture measures approx.
1/8 inches/4 mm or more.'xContact a dealerss service center or another qualified service center or repair shop if thetire cannot be made drivable.'xIf possible, do not remove foreign bodies thathave penetrated the tire. Only remove foreignobjects if they are visibly protruding from the
tire.'xPull the speed limit sticker off the sealant
container and apply it to the steering wheel.'xThe use of a sealant can damage the TPM wheel electronics. In this case, have the TPMwheel electronics replaced at the next opporjtunity.'xThe compressor can be used to check the
