Fuel specifications Tire inflation pressure Refuel with lead-freeThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
Proper inflation pressures are on a
sticker attached to the B-pillar and
visible with the driver's door open.Check tire pressuresOn the next page you will find all the tire
pressure specifications, for tires at
ambient air temperature, stated in the
units usually used in your country (psi;
kilopascal).
After correcting the tire inflation pres-
sure, re-initialize the Tire Pressure
Warning system (RDW) so that it can
monitor the tire inflation pressure, refer
to page 78.
Check tire inflation pressures
regularly Ð at least every two
weeks and before beginning a longer
trip.
Incorrect tire pressure can otherwise
lead to driving instability, tire damage
and accidents.< Comply with tire approval
specifications The inflation pressures in the table
apply to tires made by BMW-approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers. You will find
a list of approved tire sizes on
page 116.
Your vehicle is equipped with tires that
not only meet US standards, but also
European standards. We recommend
the exclusive use of BMW-approved
tires.

Tire Pressure Warning (RDW)The conceptThe Tire Pressure Warning (RDW) moni-
tors the tire pressure in all four wheels
while driving. The system detects
whenever the inflation pressure in a tire
drops significantly.
Controlling the tire pressure is based
on monitoring the speed of the tires
relative to each other. A flat tire is
detected and reported because the
speed suddenly deviate drastically from
one another.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sure.
Repeat this process after any changes
in tire inflation pressure, tire rotation or
replacement. Do not carry out further
system initialization after correcting the
inflation pressure and letting the system
"learn" what condition is required.
1 Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 27),
and adjusting their pressure if neces-
sary
2 Turn the ignition key to position 2
3 Continue to press the button until the
yellow indicator lamp in the instru-
ment cluster lights up. After a short
time, the indicator lamp will go out
automatically
4 After a few minutes, the RDW will
accept the current inflation pressure
as the value to be measured against,
and from that point on, can detect
and report a flat tire.

Tire Pressure Warning (RDW)Activating/deactivating the
systemThe system is automatically active in
ignition key position 2 and is therefore
always on during driving.
To deactivate the system: tap the
button, the indicator lamp will light up
yellow.
To activate the system: tap the button
again, the indicator lamp goes out.
Deactivate the system while driving
with snow chains, since false warnings
and undetected losses in pressure are
possible under these kinds of condi-
tions.
Flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of tire pressure loss.
In addition, an acoustic signal is
sounded. To come to an immediate
stop, reduce speed, while avoiding any
sudden, jerky braking or steering
maneuvers.
Fix the flat tire using the M Mobility
system (refer to page 145).
Reset the indicator lamp: the red indi-
cator lamp must be switched off manu-
ally after mounting a new wheel. At this
point, hold the RDW switch down until
the indicator lamp goes out. Reinitialize
the system afterward.
The RDW cannot alert you to
severe and sudden tire damage
caused by external factors.
The RDW will not identify the natural
loss of pressure in all four tires, either.<
Check the tire inflation pressure
on a regular basis and correct if
necessary. Refer to page 26.
Under certain circumstances, there
may be false warnings or a delayed
detection of pressure losses when
driving on snow-covered or slippery
road surfaces.
A sporty driving style (slip at the wheels
receiving the torque, high lateral accel-
eration) can lead to delayed RDW warn-
ings.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.

additional information.

Information for your safetyThe factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety that depend on the
condition of the tires and the mainte-
nance of the specified tire pressure.
Incorrect inflation pressure is a frequent
cause of tire damage. It also signifi-
cantly influences the roadholding ability
of your BMW.
Check tire inflation pressures on a
regular basis (refer to page 27), at
least every two weeks and before
beginning a longer trip. If this is not
done, incorrect tire pressures can
cause driving instability and tire
damage, ultimately resulting in acci-
dents.<
Tire tread Ð Tire damageInspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread depth.
Tread depth should not be allowed to
go below 0.12 in (3 mm), even though
the legally specified minimum tread
depth is only 0.063 in (1.6 mm). At a
tread depth of 0.063 in (1.6 mm), tread
depth indicators (arrow) in the tread-
groove base will indicate that the legally
permissible wear limit has been
reached. Below 0.12 in (3 mm) tread
depth, there is an increased risk of
aquaplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.
Do not drive on a deflated (flat)
tire. A flat tire greatly impairs
steering and braking response, and can
lead to complete loss of control over
the vehicle.
Avoid overloading the vehicle so that
the permitted load on the tires is not
exceeded. Overloading can lead to
overheating and increases the rate at
which damage develops inside the
tires. You could have a blowout as a
result.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle defect,
This is also true for irregularities in the
vehicle's handling characteristics, such
as a pronounced tendency to pull to the
left or right. Should this occur, respond
by immediately reducing your speed.
Proceed carefully to the nearest BMW
center or professional tire center, or
have the vehicle towed in to have it and
its tires inspected.
Tire damage (up to and including blow-
outs) can endanger the lives of both the
vehicle occupants and other road
users.<

Winter tires Snow chainsChoosing the right tire BMW recommends winter tires (M+S
radial tires) for operation under inclem-
ent winter driving conditions. While
so-called all season tires (M+S desig-
nation) provide better winter traction
than summer tires with the load ratings
H, V, W, Y and ZR, they generally do
not achieve the performance of winter
tires.
In the interests of safe tracking and
steering response, install radial tires
made by the same manufacturer and
with the same tread configuration on all
four wheels if you elect to mount winter
tires. Do not exceed specified
maximum speedsIn Germany: attach a corresponding
sign in accordance with the Federal
Motor Vehicles Safety Standards in
your field of vision if the maximum
speed of the vehicle is higher. This
sticker is available from the tire dealer
or your BMW center. Never exceed the maximum speed
for which the tires are rated.
Unprofessional attempts by laymen to
service tires can lead to damage and
accidents.
Have this work performed by skilled
professionals only. Your BMW center
will be glad to assist you with both their
expertise and the proper equipment for
your vehicle.<
Tire condition, tire pressureWinter tires display a perceptible loss in
their ability to cope with winter driving
conditions once the tread wears to
below 0.16 in (4 mm), and should thus
be replaced.
Comply with the specified tire inflation
pressure and be sure to have the
wheels balanced each time a tire or
wheel is changed. In addition, also have
the Tire Pressure Warning (RDW) reini-
tialized, for details refer to page 78.
The use of narrow-link BMW snow
chains on winter tires is approved only
in pairs and only on the rear wheels.
Comply with all manufacturer's safety
precautions when mounting the chains.
Deactivate the Tire Pressure
Warning (RDW) when using snow
chains. The snow chains can lead to
malfunction warnings and undetected
losses in pressure.
For further information, refer to
page 78.<
