Diesel exhaust fluid at the 
minimum level
Even if the display indicates -- mls, the engine 
continues running if it is not switched off and if 
all other requirements continue to be met, e.g. a 
sufficient supply of fuel.
Do not drive to the end of the indicated 
distance. Otherwise, it will not be possible 
to start the engine again after switching it off.<
Wrong fluid
A warning lamp lights up:
The wrong fluid was filled into the res-
ervoir.
Please contact your BMW center.
Having the diesel exhaust fluid refilled
Diesel exhaust fluid is refilled by your BMW 
center during regular service. If the service 
intervals are adhered to, it generally does not 
need to be refilled between service appoint-
ments.
Under certain conditions, e.g. especially fre-
quent accelerations or operation of the vehicle 
at high altitudes, it may become necessary to 
refill the fluid between service appointments.
When this reserve display appears in the instru-
ment cluster, have diesel exhaust fluid refilled to 
avoid not being able to start the engine.
You can have the fluid refilled by a BMW center.
Diesel exhaust fluid at low 
temperatures
Because of its physical properties, it may 
be necessary to refill diesel exhaust fluid 
between regular service appointments at tem-
peratures below +237/-56.
The need to add fluid is indicated by the reserve 
display in the instrument cluster, refer to 
page204.<
Refilling diesel exhaust fluid in 
exceptional cases
To be able to reach the next BMW center, you 
can refill diesel exhaust fluid yourself while 
adhering to the following warnings.
Do not come into contact with diesel 
exhaust fluid as it can lead to skin or eye 
irritations. Wear goggles and gloves, if neces-
sary. Follow the safety instructions on the bot-
tle.
Vapors with a sharp odor can escape from the 
bottle or container when it is opened. Before 
refilling, completely close the windows and 
doors of the vehicle to prevent the vapors from 
intruding into the interior. If handling diesel 
exhaust fluid in an enclosed area, ensure that 
the room is well ventilated.
After handling diesel exhaust fluid, wash your 
hands thoroughly; otherwise, for example, inad-
vertently touching your eyes may lead to eye 
irritations.
If eye irritations occur, rinse the eyes thoroughly 
with water and consult a physician if necessary.
If diesel exhaust fluid comes into contact with 
the surface of your vehicle, rinse the affected 
areas with water to prevent surface damage.
Keep diesel exhaust fluid away from children.<
Suitable diesel exhaust fluid
>Preferred: BMW Diesel Exhaust Fluid.
Diesel exhaust fluid can be refilled conve-
niently with this bottle and its special 
adapter.
>Alternatively: NOx reduction agent AUS 32
You can obtain diesel exhaust fluid from your 
BMW center.

Tire inflation pressures
Information for your safety
It is not merely the tires' service life, but also 
driving comfort and, to a great extent, driving 
safety that depend on the condition of the tires 
and the maintenance of the specified tire pres-
sure.
Check the tire inflation pressure regularly 
and correct it, if necessary: 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 condi-
tion that can not only compromise your vehi-
cle's driving stability, but also lead to tire dam-
age and the risk of an accident. Do not drive 
with deflated, i.e. flat tires, except when using 
run-flat tires. A flat tire will seriously impair your 
vehicle's handling and braking response. 
Attempts to drive on a flat tire can lead to loss of 
control over the vehicle.<
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 is higher.
After correcting the tire inflation pressure, 
reset the Tire Pressure Monitor, refer to 
page90, or reinitialize the Flat Tire Monitor, 
refer to page88.<
Inflation 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 approved and tire brands recom-
mended by BMW; a list of these is available 
from your BMW center.<
For correct identification of the right tire infla-
tion pressures, observe the following:>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up 
to 100 mph or 160 km/h
For normal driving up to 100 mph or 160 km/h 
and to achieve optimum driving comfort, adjust 
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds up to a maximum of 
100 mph or 160 km/h.
These tire inflation pressures can also be found 
on the driver's side door post when the driver's 
door is open.
The maximum permissible speed for 
these tire pressures is 100 mph or 
160 km/h. Do not exceed this speed; otherwise, 
tire damage and accidents could occur.<
Tire inflation pressures for driving 
above 100 mph or 160 km/h
In order to drive at maximum speeds in 
excess of 100 mph or 160 km/h, adjust 
pressures to the respective tire inflation pres-
sures listed on the following pages in the col-
umns for traveling speeds including those 
exceeding 100 mph or 160 km/h. Otherwise, 
tire damage and accidents could occur.<
Observe all national and local maximum speed 
limits; otherwise, violations of the laws could 
occur.

Tire identification marks
Knowledge of the labeling on the side of the tire 
makes it easier to identify and choose the right 
tires.
Tire size
Speed code letter
Q = up to 100 mph or 160 km/h
T = up to 118 mph or 190 km/h
H = up to 131 mph or 210 km/h
V = up to 150 mph or 240 km/h
W = up to 167 mph or 270 km/h
Y = up to 186 mph or 300 km/h
Tire Identification Number
Tires with DOT codes meet the guidelines of 
the US Department of Transportation.
DOT code:
Tire age
The manufacturing date of tires is contained in 
the tire coding: DOT … 1010 means that the 
tire was manufactured in week 10 of 2010.
BMW recommends that you replace all tires 
after 6 years at most, even if some tires may last 
for 10 years.
Uniform Tire Quality Grading
Quality grades can be found where applicable 
on the tire sidewall between tread shoulder and 
maximum section width. For example:
Tread wear 200 Traction AA 
Temperature A
DOT Quality Grades
Tread wear 
Traction AA A B C 
Temperature A B C
All passenger car tires must conform to 
Federal Safety Requirements 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 conditions on a specified gov-
ernment 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 conditions of their use, how-
ever, and may depart significantly from the 
norm due to variations in driving habits, service 
practices and differences in road characteris-
tics and climate.
Traction
The 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 specified government test sur-
faces 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, cor-
nering, hydroplaning, or peak traction charac-
teristics.<
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 
e.g.

Tire age
For various reasons, such as the development 
of brittleness, BMW recommends tire replace-
ment after no more than 6 years, regardless of 
the actual wear of the tires.
The manufacturing date of tires is contained in 
the tire coding: 
DOT ... 1010 means that the tire was manufac-
tured in week 10 of 2010.
Run-flat tires
The symbol identifying run-flat tires is a circle 
with the letters RSC on the sidewall. 
Run-flat tires comprise a conditionally self-sup-
porting tire and a special rim. The reinforce-
ment in the sidewalls ensures that the tire can 
continue to be used subject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat 
tire, refer to Indication of a flat tire, page89.
New wheels and tires
Have new wheels and tires installed only 
by your BMW center or tire shop that 
works according to BMW repair procedures 
with correspondingly trained personnel. If this 
work is not carried out properly, there is a dan-
ger of subsequent damage and related safety 
hazards. Make sure that the new wheels are bal-
anced.<
Retreaded tires
BMW recommends that you do not use 
retreaded tires, since driving safety may 
be impaired. The causes for this include poten-
tially different tire casing structures and often 
wide variations in tire age, which can result in 
a limited service life.<
Correct 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. In the 
event of a flat, no spare wheel is available. Your 
BMW center will be glad 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, which could 
lead to body contact and thus to severe acci-
dents. If non-approved wheels and tires are 
used, BMW cannot evaluate their suitability, 
and therefore cannot guarantee their driving 
safety.<
You can inquire about the right wheel/tire com-
bination at your BMW center.
The correct combination of wheels and tires is 
also necessary to ensure reliable operation of 
various vehicle systems such as ABS, DSC or 
FTM.
To maintain good handling and vehicle 
response, use only tires of a single brand and 
tread configuration. After a tire has been dam-
aged, mount the previous wheel and tire combi-
nation again as soon as possible.
Wheels with Tire Pressure Monitor 
TPM electronics
When mounting new tires or changing over 
from summer to winter tires, or vice versa, only 
use wheels with TPM electronics; otherwise, 
the Tire Pressure Monitor may not be able to 
detect a puncture, refer to page89. Your 
BMW center will be glad to advise you.
