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 excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle 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.
XL
Indicates specially reinforced tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm. At tread depths below 0.12 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.Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm.
New tires should be mounted in the interest of
safety.
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 been driven down to the wear indicators, a
tread depth of 0.063 in/1.6 mm has been
reached.
Wheel/tire damage
Please note that low-profile tires cause wheels,
tires and suspension parts to be more suscep-
tible to road hazards and consequential dam-
ages.
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. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed imme-
diately and have the wheels and tires
inspected immediately. To do this, carefully
drive to the nearest BMW center or a special-
ized tire dealer that works in accordance with
BMW guidelines and uses appropriately trained
personnel. Have the vehicle towed to the repair
shop if necessary. Otherwise, tire damage can
be extremely dangerous to vehicle occupants
and other road users.<

After changing wheels/tires
After changing tires or wheels, the slip detec-
tion of the Sequential Manual Transmission
must become familiar with the changed state.
Reinitialize the system for this purpose:
1.Move the selector lever into the idling
position N on a straight stretch of road at a
speed between 20 mph/30 km/h and
90 mph/150 km/h.
2.Pull both shift paddles for approx. 2 sec-
onds.
If you do not carry out initialization, the system
will automatically learn the changed state grad-
ually during driving. This may be noticeable
from the clutch opening and closing briefly.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all contact with oil, grease
and fuels. Do not exceed the maximum tire
inflation pressure indicated on the side wall of
the tire.
Rotating wheels between axles
BMW does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired.
With tires of different makes and types
* such a
change is not permissible.
Snow chains*
BMW only tests certain fine-link snow chains,
classifies them as road-safe and recommends
them. Consult your BMW center for more infor-
mation.
Use is only permitted in pairs, with winter tires
of the size 245/45 R 18 on the rear wheels.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with the chains mounted.Make sure that the snow chains are always suf-
ficiently tensioned. Readjust tension in accor-
dance with the chain manufacturer's specifica-
tions if necessary.
Do not initialize the Flat Tire Monitor after
installing snow chains as this could cause
the Flat Tire Monitor to malfunction.
After mounting or removing snow chains, the
slip detection of the Sequential Manual Trans-
mission must become familiar with the altered
state. To do this, reinitialize the system, refer to
After changing wheels/tires.<

Fast measurement
In addition to the automatic measurement, you
can also determine the current oil level manu-
ally, e.g. after adding engine oil, but with a lower
degree of measuring accuracy.
1.With the engine at operating temperature,
i.e. after at least 6 miles/10 km of uninter-
rupted driving, park the vehicle in a horizon-
tal position.
2.Allow the engine to run at idle.
3.Press the BC button in the turn signal lever
repeatedly until the oil level display is
shown in the instrument cluster.
4.Press the BC button for at least 2 seconds.
The oil level is determined. A clock symbol
is displayed during the measurement.
5.After approx. 1 minute the current oil level is
displayed.
Displaying via iDrive
iDrive, for operating principle refer to page16.

Engine oil level is being measured. This
process can take approx. 1 minute when
stopped on a level surface with the engine
running and approx. 5 minutes while driv-
ing.
If the engine oil has been topped off, the
measurement of the oil level can take up to
30 minutes.
>"Oil level at the minimum! Refill with 1 quart
of engine oil.":
Add a maximum of 1 US quart/1 liter of
engine oil at the next opportunity, refer to
Adding engine oil below. Add at least
0.5 US quart/0.5 liter. Otherwise the oil
level control may not display the new value
correctly.
If the oil level displayed is below minimum,
add engine oil immediately. Failure to do so
may lead to engine damage.
>"Engine oil level too high":
Have the vehicle checked immedi-
ately; otherwise, engine damage may
result if too much oil has been added.<

Coolant
Do not open the cooling system when the
engine is hot. Escaping coolant can cause
burns.<
Coolant is composed of equal parts water and a
coolant additive. Not all commercially available
additives are suitable for your BMW. Ask your
BMW 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.Do not open the hood until the engine has
cooled down.
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 when the upper
end of the float rod is at the same height as
the upper edge of the filler neck, also refer
to the drawing next to the filler neck.
4.If the coolant is low, slowly add coolant up to
the specified level – do not overfill.
5.Turn the cap until it clicks.
6.Have the reason for the coolant loss elimi-
nated as soon as possible.

Socket for OBD Onboard
Diagnostics interface
Components which are decisive for the
exhaust-gas composition can be checked via
the OBD socket with a device.
This socket is located under a cover on the left
side of the driver's footwell, directly under the
instrument panel.
Exhaust-gas values
The warning lamp lights up. The
exhaust-gas values are deteriorating.
Have the vehicle checked as soon as
possible.
Display of the previously described
malfunction on Canadian models.
The lamp flashes under certain conditions. This
is a sign of excessive misfiring of the engine. In
this case, you should reduce speed and drive to
the nearest BMW center as soon as possible.
Heavy engine misfiring causes serious damage
to the emission-relevant components, espe-
cially the catalytic converter, within a short time.
If the fuel filler cap is not properly tight-
ened, the OBD system can detect the
escape of fuel vapor. This causes a display to
light up. If the cap is then tightened, the display
should go out within a few days.<
Event data recorders
Your vehicle may be equipped with one or sev-
eral measuring and diagnosis modules, or with a
device for recording or transmitting certain
vehicle data or information. If you have also sub-
scribed to BMW Assist, then certain vehicle
data can be transmitted or recorded to enable
corresponding services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.
