Information for your safety It is not merely the tire's service life, but
also driving comfort and – to a great
extent – driving safety that depend on
the condition of the tires and the main-
tenance of the specified tire pressure.
Check the tire inflation pressure
regularly, including on the spare
wheel: at least every two weeks and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire dam-
age, ultimately resulting in an accident.
Do not drive with a depressurized, i.e.
flat, tire. A flat tire greatly impairs steer-
ing and braking response, and can lead
to complete loss of control over the
vehicle.<
Checking inflation pressureOnly check tire inflation pressure when
the tires are cold. i.e. after driving a
maximum of 1.25 miles/2 km or when
the vehicle has been parked for at least
2 hours. When tires are warm, the tire
inflation pressure increases.
Inflation pressure for original
equipment tiresYou will find tire inflation pressures on
the inside door pillar.Inflation pressure for other tire
sizesThe table on the next page provides the
correct inflation pressures for tires at
ambient temperature, in psi/kilopascal.
After correcting the inflation pres-
sure(s), always reinitialize the Flat
Tire Monitor, refer to page 100.< 530de225

OverviewControlsMaintenanceRepairsDataIndex
Tire identification marks Wheel/tire condition TractionThe 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 speci-
fied government test surfaces 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,
hydroplaning, or peak traction charac-
teristics.< TemperatureThe 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 condi-
tions 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 tem-
perature can lead to a sudden flat tire.
The grade C corresponds to a level of
performance which all passenger 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 separately or
in combination, can cause heat buildup
and possible a tire failure.< M+SWinter and all-season tires.
These have better winter properties
than summer tires.
Wheel/tire damage Inspect your wheels and tires frequently
for tread wear, signs of damage and for
foreign objects lodged in the tread.
Check the tread pattern depth.
Due to low-profile tires, please
note that wheels, tires and sus-
pension parts are more susceptible to
road hazard and consequential dam-
ages. Unusual vibrations encountered
during normal vehicle operation can
indicate tire failure or some other vehi-
cle defect. This can, for example, be
caused by driving over curbs. This is
also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed.
Carefully proceed – or have your vehi-
cle towed – to the nearest BMW Sports
Activity Vehicle center or tire dealer to
have the wheels or tires inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal
safety hazard for the vehicle's occu-
pants and other road users alike.<

Wheel/tire condition Replacing wheels/tiresTire treadThe tread depth should not fall below
e in/3 mm.
At tread depths below e in/3 mm there
is an increased risk of high-speed
hydroplaning, even when only small
amounts of water are present on the
road surface.
As winter tires display a noticeable loss
in their ability to cope with cold-
weather driving conditions once the
tread wears to below k/K in/4 mm, to
ensure continued safety you should
always have such tires replaced.Wear indicators at the tread-groove
base, arrow, are distributed over the
tire's circumference and are marked on
the side of the tire with TWI – Tread
Wear Indicator. These indicators signal
at a tread depth of k/FK in/1.6 mm that
the legally permitted wear limit has
been reached.

Unprofessional attempts by lay-
men to service tires can lead to
damage and accidents.
Have this work performed by skilled
professionals only. The technicians at
your BMW Sports Activity Vehicle cen-
ter will be glad to assist you with the
required professional knowledge and
specialized equipment.<
The correct wheel and tire combination
also affects various systems whose
function would otherwise be impaired,
e.g. ABS, DSC, xDrive.
Have the wheel and tire assemblies bal-
anced every time either a wheel or a tire
is replaced.
BMW does not recommend the
use of retread tires, as otherwise
driving safety may be reduced. Possible
variations in the design and the age –
which could be substantial – of the car-
casses can lead to unusually rapid
wear.<

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 manufacturing toler-
ances 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 accidents. If non-
approved wheels and tires are used,
BMW cannot evaluate their suitability,
and therefore cannot be held liable for
driving safety.<
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After a flat tire, always remem-
ber to have the original wheel and tire
combination remounted on the vehicle
as soon as possible.
Special features of winter tires BMW recommends winter tires for use
in cold winter driving conditions.
Although all-season M+S tires provide
better winter traction than summer
tires, they generally fail to provide the
same levels of cold-weather perfor-
mance as winter tires.
When switching to winter tires, observe
the description under Tire condition,
page 143, and Replacing wheels/tires.
Observing speed ratings:
Never exceed the maximum
speed for which the winter tires
are rated. Unprofessional attempts by
laymen to service tires can lead to dam-
age and accidents. Have this work per-
formed by skilled professionals only.
The technicians at your BMW Sports
Activity Vehicle center will be glad to
assist you with the required profes-
sional knowledge and specialized
equipment. place, protecting them against light
whenever possible. Always protect tires
against all contact with oil, grease and
fuels.
Do not exceed the maximum tire infla-
tion pressure indicated on the side wall
of the tire.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. BMW recommends only using
these approved, narrow-link snow
chains. Use is only permitted in pairs on
the rear wheels with the following tire
sizes:
X5 4.8is: 255/55 R 18
All other models: 235/65 R 17
Observe the manufacturer's instruc-
tions when installing snow chains.
Do not exceed a maximum speed of
30 mph/50 km/h.
After mounting snow chains, do
not initialize the Flat Tire Monitor.
When you are driving with snow chains,
it can be beneficial to switch off DSC
briefly, refer to page 95.<

sional technical training. If you are not
familiar with the regulations to be
observed, only have work on your vehi-
cle carried out by a BMW Sports Activ-
ity Vehicle center or a workshop that
uses personnel trained in accordance
with BMW requirements. If this work is
not carried out properly, there is a dan-
ger of subsequent damage and related

Engine oil Adding engine oil Wait until the level has dropped to just
above the lower mark before adding oil.
Continuous exposure to used oil
has caused cancer in laboratory
testing. For this reason, any skin areas
that come into contact with oil should
be thoroughly washed with soap and
water.
Always store oils, grease and similar
materials so that they are inaccessible
to children. Comply with warning labels
and information on containers.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of used oil.< 530de326
Specified engine oils The quality of the engine oil selected
has critical significance for the opera-
tion and service life of an engine.
Based on extensive testing, BMW has
approved only certain engine oils.
Use only approved BMW High Perfor-
mance Synthetic Oil.
If you are unable to obtain BMW High
Performance Synthetic Oil, you can add
small amounts of synthetic oil in
between oil changes. Use only oils with
the API SH specification or higher.
Ask your BMW Sports Activity
Vehicle center for details concern-
ing the specific BMW High Perfor-
mance Synthetic Oil or synthetic oils
which have been approved.<

BMW engines are designed to
operate without additives, and
their use could even lead to damage in
some cases.<
Viscosity ratings Viscosity is the oil flow rating as estab-
lished in SAE classes.
The selection of the correct SAE class
depends on the climatic conditions in
the area where you typically drive your
BMW.
Approved oils are in SAE classes
5W-40 and 5W-30.<
These oils may be used for driving in all
ambient temperatures.

Brake fluidBrake fluid level
If the warning lamp lights up
or the message "CHECK
BRAKE FLUID" appears in the
Check Control: stop immedi-
ately. The brake fluid in the res-
ervoir has fallen to below the
minimum level.
Add brake fluid The brake fluid reservoir is located
under the microfilter housing trim panel
on the driver's side of the vehicle. For
adding brake fluid or for determining
and correcting the cause of brake fluid
loss, consult your BMW Sports Activity
Vehicle center. Your BMW Sports
Activity Vehicle center is familiar with
the specifications for factory-approved
DOT 4 brake fluids.
Brake fluid loss may result in extended
brake pedal travel. For this situation,
refer to the notes on page 139.
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW Sports Activity Vehicle center.
Refer also to the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
Brake fluid is toxic and also damages
vehicle paintwork. Always store these
agents in tightly-closed original con-
tainers kept well away from the reach of
children.
Do not spill the fluid and do not refill the
brake fluid reservoir to beyond the MAX
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Always observe all applicable
environmental rules and regula-
tions when disposing of used brake
fluid.<

The BMW Maintenance System is
designed in such a way that it reliably
ensures the road safety and operating
reliability of the vehicle, keeping the
cost for you as low as possible.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining the resale
value of the vehicle.
Service Interval Display Conventional systems rely solely on
distance traveled to determine when
service is due. The BMW Maintenance
System, on the other hand, began many
years ago to take the actual conditions
under which the vehicle is driven into
consideration. After all, different drivers 390us008
can accumulate mileage in very differ-
ent ways:
From the point of view of maintenance,
62,000 miles/100,000 km accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate speeds in long-
distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
Determining the maintenance intervals
according to the actual loads on the
vehicle covers every kind of operating
situation. However, even those who
drive only short distances, significantly
less than 6,000 miles/10,000 km annu-
ally, should have the engine oil changed
at least every 2 years since oil deterio-
rates over time, regardless of use. Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian models For additional information on mainte-
nance intervals and procedures, please
refer to the Service and Warranty Infor-
mation Booklet for US models or the
Warranty and Service Guide Booklet for
Canadian models. As a precaution against corrosion, it is
advisable to have the body checked for
damage from rocks or gravel at the
same time, depending upon operating
conditions.
Have your BMW Sports Activity
Vehicle center do the mainte-
nance and repair.
Be sure that all maintenance work is
confirmed in the Service and Warranty
Information Booklet for US models or
the Warranty and Service Guide Book-
let for Canadian models.
These entries will constitute your proof
that the vehicle has received regular
maintenance. They are also required for
