Information for your safety The condition of the tires and the main-
tenance of the specified tire pressure
are crucial not only to the tire's service
life, but also to driving comfort and
most importantly, driving safety. Checking pressureOnly 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 spare 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 impairs 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 inflation pres-
sure(s), always reinitialize the Flat
Tire Monitor, refer to page99.<
Inflation pressures for factory-
installed tiresThe tire inflation pressure specifications
for your factory-installed tires at ambi-
ent temperature are listed on the edge
of the driver's door and can be con-
sulted when the door is open.Inflation pressuresThe tire pressure tables in the following
pages give all of the pressure specifica-
tions for the tire sizes indicated at ambi-
ent temperature.
The inflation pressures apply to
the tire sizes and tire brands
respectively approved and recom-
mended by BMW; a list of these is avail-
able from your BMW Sports Activity
Vehicle center.<530de225

DOT code: Tire age The manufacturer of your BMW recom-
mends that all tires, i.e. including the
spare wheel, be replaced regardless of
the actual wear after 6 years at the lat-
est.
The tire's date of manufacture is indi-
cated on the sidewall:
DOT... 2605 indicates that the tire was
manufactured in week 26 of 2005. Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: e.g.
Manufacturer's code
for tire brand
Tire size and tire model
Tire age
DOT xxxx xxx 2605
DOT Quality Grades Tread wear
Traction AA A B C
Temperature A B C
All passenger car tires must con-
form to Federal Safety Require-
ments 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 condi-
tions on a specified government 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 condi-
tions of their use, however, and may
depart significantly from the norm due
to variations in driving habits, service
practices and differences in road char-
acteristics and climate.

Replacing wheels/tires
Have new wheels and tires
installed only by your BMW Sports
Activity Vehicle center or tire shop that
works according to BMW repair proce-
dures with correspondingly trained per-
sonnel. If this work is not carried out
properly, there is a danger of subse-
quent damage and related safety haz-
ards.<
Retreaded tires
BMW does not recommend the
use of retreaded tires, otherwise
driving safety may be reduced. The rea-
son for this is that possible variations in
the design and aging – which could be
substantial – of the tire casing 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 fac-
tors such as manufacturing tolerances
mean that even wheels and tires with
identical official size ratings could actu-
ally 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.<
You can ask your BMW Sports Activity
Vehicle center for the correct wheel/tire
combination.
The correct wheel/tire combination also
affects various systems whose function
would otherwise be impaired, e.g. ABS,
DSC, xDrive.
To maintain good handling and vehicle
response, use only tires of a single
tread configuration from a single manu-
facturer. After tire damage, always
remember to have the original wheel
and tire combination remounted on the
vehicle as soon as possible.
Recommended tire brands:
BMW recommends particular tire
brands for each tire size. You will rec-
ognize them by the clearly visible BMW
identification on the tire sidewall.
With proper use, these tires meet the
highest standards for safety and han-
dling characteristics.530de424

Replacing wheels/tires Snow chains
*
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,
page146, 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.<
Storage Store wheels or tires in a cool, dry
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 fine-link snow chains are
tested, classified as road-safe, and rec-
ommended by BMW. Consult your
BMW Sports Activity Vehicle center for
details. 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
Follow the manufacturer's instructions
when installing snow chains. Do not
exceed a maximum speed of 30 mph/
50 km/h.
Do not initialize the Flat Tire Moni-
tor after mounting snow chains, as
the monitor may then incorrectly indi-
cate flat tires.
When you are driving with snow chains,
it can be beneficial to switch off DSC
briefly, refer to page93.<

Lamps and bulbs Changing a wheel Light-emitting diodes LEDs Light-emitting diodes installed behind
translucent lenses serve as the light
source for many of the controls and dis-
plays in your vehicle. The concept
behind their operation is related to that
employed for lasers.
Do not remove the covers, and
never stare into the unfiltered light
several hours, as irritation of the retina
could result.<
Safety precautions to observe in
the event of a flat and during all
tire changes:
Park the vehicle as far as possible from
passing traffic. Park on a firm, flat, sur-
face. Switch on the hazard warning
flashers.
Turn the steering wheel to the straight-
ahead position, remove the key and
engage the steering lock. Shift into 1st
or reverse, selector lever in Park with
automatic transmission, and engage the
handbrake.
All passengers should be outside the
vehicle and well away from your imme-
diate working area, behind a guardrail,
for instance.
If a warning triangle or portable hazard
warning lamp is required, set it up on
the roadside at an appropriate distance
from the rear of the vehicle. Comply
with all safety guidelines and regula-
tions.
Change the wheel only on a level, firm
surface that is not slippery. The vehicle
or the jack could slip to the side if you
attempt to raise the vehicle on a soft
or slippery surface such as snow, ice,
tiles, etc.
Position the jack on a firm support sur-
face.
Do not place wooden blocks or similar
objects under the jack. If this is done,
the jack might not be able to reach its
full support capacity because of the
limited height. To avoid serious or fatal
injury: never lie under the vehicle, and
never start the engine while it is sup-
ported by the jack.<
Your BMW has either a compact wheel
for temporary use to ensure your mobil-
ity, or a spare wheel of the size 235/
65 R 17. Please observe the differences
in handling when removing the wheel
from the cargo area.

Changing a wheel Vehicle battery
Only one compact wheel may be
mounted. Wheels and tires of the
original size should be mounted again
as soon as possible.<
Driving with spare wheel
*
Do not exceed a speed of
130 mph/210 km/h, otherwise tire
damage could lead to accidents.<
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. To restore the original state,
the normal wheel should be remounted
as soon as possible.<
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands after
handling.<
Battery care The battery is maintenance-free, that is,
the original electrolyte will normally last
for the service life of the battery under
moderate climatic conditions. Your
BMW Sports Activity Vehicle center will
be glad to advise in all matters con-
cerning the battery.Charging battery Only charge the battery in the vehicle
via the terminals in the engine compart-
ment with the engine off. For correct
connections, refer to Jump starting on
page174. Disposal
Following replacement, have old
batteries disposed of by your
BMW Sports Activity Vehicle center or
turn them over to a recycling center.
Maintain the battery in an upright posi-
tion for transport and storage. Always
restrain the battery to prevent it from
tipping over during transport.<
Power failure Following a temporary power failure,
e.g. in the case of a dead battery, some
equipment is subject to restricted use
and must be reinitialized. Individual set-
tings are also lost and must be updated
again:
>Seat, mirror and steering wheel
memory
The positions must be stored again,
refer to page50
