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 th e 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 esca pe. Before refilling,
close the vehicle complete ly so that the vapors
do not get into the interi or 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 inadve rtent contact with the
eyes.
If eye irritation occurs, immediately rinse eyes
with ample water and cont act 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 el se 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.
Refilling quantity
Refilling quantity at the start of the reserve dis-
play: approx. 0.75 US gal/2.7 Liter
Open reservoir for diesel exhaust fluid
1. Open hood, refer to page 258.
2. Fit releasing tool from onboard tool kit, refer
to page 269 into place and open the lock,
refer to arrow.
Refilling BMW diesel exhaust fluid
1. Set bottle into place and rotate until it
comes into contact with the stop, refer to
arrow.
2. Press bottle down, refer to arrow.
The reservoir of the vehicle is filled.
3. The reservoir is full when the fill level in the
bottle stops changing. It is not possible to
overfill.

Pull bottle back, refer to
arrow, and unscrew
it.
Closing reservoir
After the reservoir is filled, close it again with the
releasing tool.
After refilling diesel exhaust fluid
Incorrect fluid
After refilling with the incorrect fluid, e.g.
antifreeze for windshield wiper fluid, do
not start the engine because this could result in
a fire hazard. <
Contact your BMW Sports Activity Vehicle
Center.
Bottle disposal
You can have bottles for diesel exhaust
fluid properly disposed of at your BMW
Sports Activity Vehicle Center.
Only dispose of empty bottles in your house-
hold garbage if the local legal regulations permit
it.<
Reserve display
After refilling, the reserv e continues to appear
after the engine is rest arted. After the vehicle has been driven for a few more minutes, this
display will disappear.

Wheels and tires
Tire inflation pressure
Information for your safety
The condition of the tires and the maintenance
of the specified tire pres sure 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 de pressurized, i.e. flat
tires, except run-flat tires. A flat tire will seri-
ously impair your vehicle's handling and braking
response. Attempts to dr ive 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
page 100, or reset the Tire Pressure Monitor,
refer to page 102.<
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
Activity Vehicle Center. <
For correct identification of the right tire infla-
tion pressure for your tires, observe the follow-
ing:
> Tire sizes of your vehicle
> Load conditions
> Maximum allowable driving speed
Tire inflation pre ssures for speeds
up to 100 mph/160 km/h
For normal driving up to 100 mph/160 km/h,
adjust pressures to the re spective 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 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 letter
Q = up to 100 mph/160 km/h
T = up to 118 mph/190 km/h
H = up to 131 mph/210 km/h
V = up to 150 mph/240 km/h
W = up to 167 mph/270 km/h
Y = up to 186 mph/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 ... 3008 indicates that the
tire was manufactured in week 30 of 2008.
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 betw een 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 (1 γ) times as
well on the government course as a tire graded
100. The relative perfor mance of tires depends
upon the actual conditio ns 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.
These grades represent th e tire's ability to stop
on wet pavement, as measured under con-
trolled conditions on specified government test
surfaces of asphalt and concrete. A tire marked
C may have poor traction performance.
The traction grade assign ed to this tire is
based on straight-ahead braking traction
tests, and does not in clude acceleration, cor-
nering, hydroplaning, or peak traction charac-
teristics. <
