Indicator and warning lamps
Technology that monitors itself
Indicator and warning lamps that are identified
with
+ are checked for proper function each
time you turn the ignition key. They each light
up once for different periods of time.
When a malfunction occurs in a monitored sys-
tem, the corresponding lamp will either fail to go
o u t w h e n t h e e n g i n e i s s t a r t e d , o r i t w i l l c o m e o n
again during normal driving. Detailed informa-
tion is provided on the specified pages.

Wheels and tires
98 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.<
Correct 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 tire
damage, always remember to 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 page55. 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.
Changing wheels from one axle to
another
BMW does not recommend changing the front
wheels to the back or vice versa as this can
impair handling characteristics.

Engine oil
Engine oil consumption depends on driving
style and operating conditions.
Warning lamp
Engine oil pressure
The warning lamp lights up red:
The engine oil pressure is too low.
Stop the vehicle immediately and
switch off the engine. Check the engine oil level
and top off as needed. If the oil level is correct:
Have the system checked immediately.
Do not continue driving. The engine could
be damaged because of inadequate lubri-
cation.<
Engine oil level
The warning lamp lights up yellow dur-
ing driving. An acoustic signal also
sounds and "+1.0 " is displayed in the
instrument cluster, refer to page102.
The oil level is at its absolute minimum; top off
engine oil as soon as possible. Until then, do not
drive more than approx. 125 miles/200 km.
The warning lamp lights up yellow after
the engine is switched off. In addition, a
signal sounds.
Top off engine oil at the earliest opportunity,
e.g. with your next refueling.
The warning lamp lights up yellow
within 30 seconds after starting the
engine:
The oil level sensor has failed. It is not possible
to take a current or meaningful measurement.
Have the system checked as soon as possible.
Checking oil level
Your vehicle is equipped with an electronic oil
level control.
For the most precise possible display of the oil
level, the engine must be at operating tempera-
ture, i.e. after at least 6.5 miles/10 km of unin-
terrupted driving. You can have the oil level dis-
played while you drive or while the vehicle is standing on a flat surface with the engine run-
ning.
You can have the current oil level displayed in
the instrument cluster.
Press button1. The oil level is checked and dis-
played for approx. 15 seconds.
In order to cancel the display early, press but-
ton 1 again.
Possible displays
1Oil level OK
2Oil level is being detected
This process can last approx. 3 minutes
while standing on a flat surface and approx.
5 minutes while driving.
