Have diesel exhaust fluid refilled
Your BMW Sports Activity Vehicle Center refills
the diesel exhaust fluid as part of the regular
maintenance. If you adhere to this maintenance
schedule, it is usually not necessary to refill any
fluids between the maintenance dates.
Under certain circumstances, e.g. due to a par-
ticularly sporty driving style or operation of the
vehicle at high altitudes, it may be necessary to
refill fluids between maintenance dates.
As soon as the reserve display has appeared in
the instrument panel, have the diesel exhaust
fluid refilled to prevent the engine from being
unable to restart.
You can have the fluid refilled by a BMW Sports
Activity Vehicle Center.
Diesel exhaust fluid at low
temperatures
Due to its physical properties, it may be
necessary to replenish the level of diesel
exhaust fluid at temperatures below +237/
-56 even between the regular maintenance
intervals.
If the fluid needs to be refilled, this will be indi-
cated with the reserve display in the instrument
panel, refer to page236.<
Only refill the diesel exhaust fluid
yourself in exceptional circumstances
In order to get your vehicle to reach the nearest
BMW Sports Activity Vehicle Center, you may
refill the diesel exhaust fluid yourself, making
sure to heed the warning notices.
Do not allow diesel exhaust fluid to come
into contact with you. This can lead to
skin and eye irritation. Wear protective goggles
and gloves as needed. Follow the safety
instructions on the bottle.
When opening the bottle or reservoir, pungent
smelling vapors can escape. Before refilling,
close the vehicle completely so that the vapors
do not get into the interior of the vehicle. When
handling diesel exhaust fluid in enclosed
spaces, make sure to have sufficient ventilation.
After handling diesel exhaust fluid, wash hands
thoroughly. Failure to do so may lead to irrita-tion, e.g. due to inadvertent contact with the
eyes.
If eye irritation occurs, immediately rinse eyes
with ample water and contact a doctor if neces-
sary.
If diesel exhaust fluid comes into contact with
surfaces of your vehicle, rinse the affected sur-
faces with water or else damage may occur.
Keep diesel exhaust fluid out of reach of chil-
dren.<
Suitable diesel exhaust fluid
>Preferred: BMW Diesel Exhaust Fluid.
This bottle and its special adapter permit
convenient refilling with diesel exhaust
fluid.
>Alternative: NOx reduction agent AUS 32
You can get diesel exhaust fluid at your BMW
Sports Activity Vehicle Center.

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 tire
*: at least twice a month and before
starting long trips. If you fail to observe this pre-
caution, you may be driving on tires with incor-
rect 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 acci-
dent. Do not drive with depressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to drive on a flat tire can
lead to a loss of control over the vehicle.<
After correcting the tire inflation pressure,
reinitialize the Flat Tire Monitor, refer to
page100, or reset the Tire Pressure Monitor,
refer to page102.<
Pressure specifications
The tables below provide all the correct inflation
pressures for the specified tire sizes at ambient
temperature.
The inflation pressures apply to the tire
sizes and tire brands respectively
approved and recommended by BMW; a list of
these is available from your BMW Sports Activ-
ity Vehicle Center. tion pressure for your tires, observe the follow-
ing:
>Tire sizes of your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the respective tire inflation
pressures listed on the following pages in the
column Traveling speeds up to max. of
100 mph/160 km/h to achieve optimum driving
comfort.
These pressure specifications can be found on
the door post when you open the driver's door.
The permissible top speed for these tire
inflation pressures is 100 mph/160 km/h.
Do not exceed this speed, otherwise tire dam-
age and accidents may result.<
Tire inflation pressures for speeds
above 100 mph/160 km/h
In order to drive at maximum speeds in
excess of 100 mph/160 km/h, please
observe, and, if necessary, adjust tire pressures
for speeds exceeding 100 mph/160 km/h from
the relevant table on the following pages. Oth-
erwise tire damage and accidents could
occur.<

Wheels and tires
248 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.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page249.
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 for foreign objects lodged
in the tread. Check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3mm, 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.
When winter tires wear down past a tread depth of 0.16 in/4 mm, they become perceptibly less
suitable for winter conditions. For the sake of
safety, new tires should be installed.
Wear indicators at the tread-groove base are
distributed over the tire's circumference 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 speed immedi-
ately and have wheels and tires thor-
oughly checked. To do so, drive carefully to the
nearest BMW Sports Activity Vehicle Center or
tire shop that works according to BMW repair
procedures with correspondingly trained per-
sonnel. If necessary, have the vehicle towed
there. Otherwise, tire damage can be extremely
dangerous to vehicle occupants and other road
users.<

Run-flat tires
You will recognize run-flat tires by the circular
symbol containing the letters RSC on the side
of the tire.
Run-flat tires consist of partially self-contained
tires and special rims. The sidewall reinforce-
ment ensures that the tire retains some residual
safety in the event of pressure drop and driving
remains possible to a restricted degree.
To continue driving with a damaged tire:
>With Flat Tire Monitor, refer to Indication of
a flat tire page100
>With Tire Pressure Monitor, refer to Mes-
sage with low tire inflation pressure
page103
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-
age and related safety hazards. Make sure that
the new wheels are balanced.<
Retreaded tires
BMW does not recommend that you use
retreaded tires, as driving safety may be
impaired. The causes for this include the possi-
bly 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
When mounting new tires or changing over
from summer to winter tires and vice versa,
mount Run-flat tires for your own safety. Your
BMW Sports Activity Vehicle Center will be
happy to advise you.
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.<
When changing to larger wheels and tires,
it may be necessary to make changes to
the wheelwell trim piece, as otherwise road
users could be endangered or the vehicle could
be damaged. Only have this work carried out by
a BMW Sports Activity Vehicle Center or a
workshop that works in accordance with BMW
guidelines and uses appropriately trained per-
sonnel.<
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 other-
wise be impaired, e.g. ABS, DSC, xDrive,
Dynamic Performance Control in the BMW X6,
or Flat Tire Monitor.
To maintain good handling and vehicle
response, use only tires of a single tread config-
uration from a single manufacturer. Following
tire damage, have the original wheel and tire
combination remounted on the vehicle as soon
as possible.
Wheels with electronics for
TPM Tire Pressure Monitor
When mounting new tires or changing from
summer to winter tires or vice versa, only use
wheels with TPM electronics, otherwise the
