Wheels and tires
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 wheel: at least twice a month and
before starting long trips. If you fail to observe
this precaution, you may be driving on tires with
incorrect tire pressures, a condition that can not
only compromise your vehicle's driving stability,
but also lead to tire damage and the risk of an
accident.
Do not drive with deflated, i.e. 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 loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor
* or reset
the Tire Pressure Monitor
*, refer to pages51,
52.<
Pressure specifications
The table on the next page provides all the cor-
rect inflation pressures for the specified tire
sizes at ambient temperature.
The inflation pressures in the table apply
to BMW-approved tire sizes and recom-
mended tire brands. Your BMW Sports Activity
Vehicle Center will be glad to supply this infor-
mation. tion pressure for your tires, please note the fol-
lowing:
>Tire size for your vehicle
>Load status
>Maximum permissible driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving at speeds of up to 100 mph/
160 km/h and to achieve an optimal driving
comfort, take note of the tire inflation pressures
listed on the following page in the column for
speeds up to max. 100 mph/160 km/h and
adjust your tire pressure as needed.
These tire inflation pressures are also listed on
the door pillar and can be seen with the driver's
door open.
The maximum permissible speed for
these tire inflation pressures is 100 mph/
160 km/h. Do not exceed this speed; failure to
heed this limit can lead to tire damage and acci-
dents.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds
above 100 mph/160 km/h, take note of
the tire inflation pressures listed in the column
for speeds above 100 mph/160 km/h in the
table on the following page and adjust your tire
pressure as needed. Failure to due so can lead
to tire damage and accidents.<

Temperature
The temperature grades are A, B, and C, A
being highest, and represent the tire’s resis-
tance 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 corre-
sponds to a level of performance that all pas-
senger car tires must meet under the Federal
Motor Vehicle 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.<
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not fall below 0.12 in/
3 mm. At tread depths below 0.12 in/3 mm,
there is an increased risk of high-speed hydro-
planing, even when only small amounts of water
are present on the road surface.
Winter tires display a noticeable loss in their
ability to cope with cold-weather driving condi-
tions once the tread wears to below 0.16 in/
4 mm. To ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the tire tread
has worn down to the wear indicators, then the
legally permissible tread depth limit of 0.063 in/
1.6 mm has been reached.
Wheel/tire damage
Please note that low-profile tires, make
wheels, tires and suspension parts more
susceptible to road hazard and consequential
damages.<
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. The same
applies to any other abnormal road behavior,
such as pulling severely to the right or left.
In these cases, reduce speed immedi-
ately and have wheels and tires checked
immediately. Drive carefully to the nearest
BMW Sports Activity Vehicle Center or tire spe-
cialist. Have the vehicle towed to one of these
locations if necessary.
Tire damage can pose a potentially lethal safety
hazard for the vehicle's occupants and other
road users alike.<
New wheels and tires
Have new wheels and tires installed only
by your BMW Sports Activity Vehicle
Center or a tire shop that works according to
BMW repair procedures with correspondingly
trained personnel. If this work is not carried out
properly, there is a danger of subsequent dam-

Wheels and tires
90 age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend the use of
retreaded tires; otherwise, driving safety
may be reduced. The causes for this include the
possibly different tire casing structures and the
often wide variations in their age, which can
result in a limited service life.<
The right wheels and tires
BMW recommends that you use only
wheel and tire combinations that BMW
has tested and approved for your particular
vehicle. Variations in factors such as manufac-
turing tolerances mean that even wheels and
tires with identical official size ratings could
actually have different dimensions than the
approved units – these differences could lead to
body contact and with it, the risk of severe acci-
dents. If non-approved wheels and tires are
used, BMW cannot evaluate their suitability,
and therefore cannot be held liable for driving
safety.<
You can ask your BMW Sports Activity Vehicle
Center for the correct wheel-and-tire combina-
tion.
The correct wheel-and-tire combination affects
various systems whose function would other-
wise be impaired, e.g. ABS, DSC or xDrive.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. After a flat
tire, always have the original wheel-and-tire
combination remounted on the vehicle as soon
as possible.
Wheels equipped with electronics for
TPM Tire Pressure Monitor
When installing new tires or when changing
from summer tires to winter tires or vice versa,
only use wheels equipped with TPM electron-
ics; otherwise, the Tire Pressure Monitor can-
not detect a flat tire, refer to page52. Your
BMW Sports Activity Vehicle Center will be
happy to advise you in this regard.
Recommended tire brands
BMW recommends particular tire brands for
each tire size. You will recognize them by the
clearly visible BMW identification on the tire
sidewall.
With proper use, these tires meet the highest
standards for safety and handling characteris-
tics.
Special characteristics of winter tires
BMW recommends winter tires for use in cold
winter driving conditions. Although all-season
M+S tires do provide better winter traction than
summer tires, they generally fail to provide the
same levels of cold-weather performance as
winter tires.
Observing speed ratings
Never exceed the maximum speed for
which the winter tires are rated.<
Storage
Store wheels or tires in a cool, dry place, pro-
tecting them from light whenever possible. Pro-
tect the tires from contact with oil, grease and
fuel. Do not exceed the maximum tire inflation
pressure indicated on the side wall of the tire.

Approved engine oils
The quality of the engine oil selected has critical
significance for the operation and service life of
an engine. BMW continuously approves spe-
cific oils after confirming their suitability for use
in its vehicles with extensive testing.
Only use approved BMW High Performance
Synthetic Oil.
If you are unable to obtain BMW High Perfor-
mance Synthetic Oil, you can add small
amounts of another synthetic oil in between oil
changes. Only use oils with the API SH specifi-
cation or higher.
Ask your BMW Sports Activity Vehicle
Center for more details concerning BMW
High Performance Synthetic Oil or other
approved synthetic oils.<
You can also call BMW of North America at
1-800-831-1117 or visit website
www.bmwusa.com to obtain this information.
BMW engines are designed to operate
without additives, and their use could
even lead to damage in some cases.<
Viscosity classes
Viscosity is the oil flow rating as defined in
SAE classes.
The selection of the correct SAE class depends
on the climate conditions in the area where you
typically drive your BMW.
Approved oils belong to SAE classes
5W-40 and 5W-30.<
These oils can be used for driving in all ambient
temperatures.
Coolant
Warning lamp
The warning lamp lights up: coolant
level is too low; top off at the next
opportunity.Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant consists of water and coolant additive.
Not all commercially available additives are suit-
able for your BMW. Ask your BMW Sports
Activity Vehicle Center for suitable additives.
Only use suitable additives; otherwise,
engine damage may result. The additives
present a health hazard.<
Always observe all applicable environ-
mental laws and regulations when dis-
posing of used coolant additives.<
Checking coolant level
1.The engine must be at ambient tempera-
ture.
2.Turn the cap of the expansion tank counter-
clockwise to allow any accumulated pres-
sure to escape, then continue turning to
open.
3.The coolant level is correct if the upper end
of the red float bar is at least at the same
height as the top edge of the filler neck,
refer to arrow. The bar end may only pro-
trude by a maximum of ιin/2 cm, i.e. up to
the second mark on the float bar, refer also
to drawing beside the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Screw on the cap and tighten snugly.
6.Have the reason for the coolant loss cor-
rected as soon as possible.

Maintenance
The BMW maintenance
system
The BMW maintenance system supports the
preservation of the road and operating safety of
your BMW.
Regular maintenance is not only required for
the safety of the vehicle, it also improves the
resale value.
Service Interval Display
The BMW maintenance system takes the driv-
ing conditions of the vehicle into account when
determining service intervals:
From the maintenance standpoint,
62,000 miles/100,000 km accumulated in
short-distance urban driving are not the equiva-
lent of the same distance covered at moderate
speeds in long-distance highway travel.
The BMW maintenance system is divided into
engine oil service and Inspections I and II.
Determining the maintenance intervals accord-
ing to the actual loads on the vehicle covers
practically every kind of operating situation.
However, even those who drive only short dis-
tances, significantly less than 6,200 miles/
10,000 km annually, should have the engine oil
changed at least every 2 years since oil deterio-
rates over time, regardless of use.
Brake fluid is hygroscopic: it absorbs
moisture from the atmosphere over the
course of time. To ensure that the brake system
continues to provide safe and reliable perfor-
mance, remember to have the brake fluid changed at least every two years by a BMW
Sports Activity Vehicle Center, also refer to the
Service and Warranty Information Booklet for
US models or the Warranty and Service Guide
Booklet for Canadian models.<
