Fuel specifications Tire inflation pressureThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI.
AKI = Anti Knock Index
Never use leaded fuel, as it would
cause permanent and irreversible
damage to the 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 pressuresAll pressures are specified in the usual
units of the respective country (psi; kilo-
pascal) for tires at ambient temperature
(also refer to the following tire inflation
pressure table).
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor so
that it can monitor the tire inflation
pressure, refer to page 82.
Check your tire pressures on a
regular basis Ð at least twice a
month Ð and before every extended
journey. 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 BMW approved tire sizes and tire
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
made by other manufacturers.
Your vehicle is equipped with tires
which not only meet US standards, but
also European standards. We recom-
mend the exclusive use of BMW
approved tires.

Dynamic Stability Control (DSC) Flat Tire MonitorTo deactivate the systemPress the button; the indicator lamp
comes on and stays on.
The vehicle does not execute the
stability-enhancement and traction-
control functions when DSC is deacti-
vated.
We recommend that you deactivate the
system for increased traction:
>when rocking the vehicle or starting
off in deep snow or on loose surfaces
>or when driving with snow chains.
To maintain vehicle stability,
always drive with the system
switched on whenever possible.<
To reactivate the systemPress the button again; the indicator
lamp goes out.Dynamic Brake Control (DBC)DBC is an integral component of the
DSC system.
If you apply the brakes rapidly, this
system automatically generates
maximum braking force boost and thus
helps to achieve the shortest possible
braking distance in "panic braking" situ-
ations. All of the benefits of the ABS
system are exploited under these
circumstances.
Do not reduce the pressure on the
brake pedal for the duration of the
brake application. When the brake
pedal is released, the DBC is deacti-
vated.
The conceptThe Flat Tire Monitor keeps track of the
inflation pressures in your tires as you
drive. The system detects whenever the
inflation pressure in a tire drops off
significantly.
Controlling the tire pressure is based
on monitoring the rpms that the tires
have relative to each other. A flat tire is
detected and reported because the
rpms suddenly deviate drastically from
one another.

OverviewControlsMaintenanceRepairsDataIndex
Flat Tire MonitorInitializing 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.
1. Check the tire inflation pressure in all
the tires, comparing them with the
inflation pressure table (page 25),
and adjusting their pressure if neces-
sary
2. Turn the ignition key to position 2
3. Press button as long as you need to
until the indicator lamp in the instru-
ment cluster lights up. After a little
while, the indicator lamp will go out
by itself
4. After a few minutes, the Flat Tire
Monitor will accept the current infla-
tion pressure as the value to be
measured against, and from that
point on, can detect and report a flat
tire.
Activating/deactivating the
systemThe system is automatically activated in
ignition key position 2 and conse-
quently is on whenever the vehicle is
operated.
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 when snow
chains are mounted, since false warn-
ings and undetected losses in pressure
are possible under these kinds of
conditions.

Flat Tire Monitor
M Engine dynamics control
Flat tire
The indicator lamp in the instru-
ment cluster will light up red in
the event of a flat tire with
ensuing loss in pressure. 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 132).
Resetting the indicator lamp: the red
indicator lamp has to be switched off
manually after putting on a new wheel.
At this point, hold the Flat Tire Monitor
button down until the indicator lamp
goes out. Reinitialize the system after-
ward.
The Flat Tire Monitor cannot alert
you to severe and sudden tire
damage caused by external factors.
Another factor which the Flat Tire
Monitor does not recognize is the
balanced and very gradual pressure
loss that takes place in all tires over an
extended period of time.<
Check the tire inflation pressure
on a regular basis and correct if
necessary, refer to page 24.
Under certain circumstances, there
may be false warnings or a delayed
detection of losses in pressure when
driving on snow-covered or slippery
road surfaces.
Performance-oriented driving (slip at
the drive wheels, high levels of lateral
acceleration) can also delay the
appearance of status reports in the Flat
Tire Monitor's display panel.<
System malfunctionAs long as there is still a malfunction,
the indicator lamp in the instrument
cluster will stay lit up yellow.
Please contact your BMW center for
additional information.
The system (Sport mode identification)
will cause the engine to respond spon-
taneously to the motion of the acceler-
ator pedal. Activating/deactivating
sport-mode identificationActivating: with the key in ignition key
position 2, press the sport button. The
indicator lamp will light up.
The vehicle may gain speed
without any additional pressure on
the accelerator pedal when the system
is activated.<
Deactivating: press the sport button
again; the indicator lamp will go out.
The sport mode is deactivated every
time the engine is started.

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 24), at
least every two weeks and before every
long trip. If this is not done, incorrect
tire pressures can cause driving insta-
bility and tire damage, ultimately
resulting in accidents.<
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). Tread wear indi-
cators (arrow) are embedded in the base
of the tire's tread. Their locations are
indicated by the legend "TWI" Ð Tread
Wear Indicator Ð at various points on the
tire's shoulder. When the tread reaches a
depth of 0.063 in (1.6 mm), these indica-
tors appear to signal that the tires have
worn to the minimum legal level. 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.
The type of problem can be caused by
contact with curbs, etc. 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 immedi-
ately 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 wheels
and 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 chains** * *Choosing the right tireBMW recommends winter tires (M+S
radial tires) for driving in adverse winter
road conditions. So-called all-season
tires with the M+S identification mark
do indeed possess better winter trac-
tion than summer tires that have the H,
V, W, Y and ZR speed ratings, they
generally fail to provide the same levels
of performance as snow 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.
When mounting winter wheels,
observe the different recess on
the front and rear wheels, as otherwise
damage may result.<
Do not exceed specified
maximum speeds
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 pressureOnce winter tires wear to a tread depth
of less than 0.16 inches (4 mm), their
performance under winter driving
conditions deteriorates noticeably.
Worn tires should therefore be replaced
for safety considerations.
Comply with the specified tire inflation
pressures Ð and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
The use of fine-link BMW snow chains
is only permitted in pairs with the winter
tires on the rear wheels. Comply with all
manufacturer's safety precautions
when mounting the chains. Do not
exceed a maximum speed of 30 mph
(50 km/h) with snow chains.
After mounting or removing snow
chains, always reinitialize the sequential
M gearbox
* SMG II, refer to page 83.
It is not possible to mount snow
chains on tires with 18- and
19-inch wheels.
Deactivate the Flat Tire Monitor when
using snow chains. Malfunction warn-
ings and undetected losses in pressure
are a possibility when driving with snow
chains.
For further information, refer to
page 82.<

Repairing a flat tire2. Flip open the cover and pull out the
enclosed protective gloves. Take out
hose 2 with the manometer and
screw it to the terminal for the
sealant container as shown in the
illustration
3. Make sure that the system has been
switched off (position 0).
Take out plug 6 and plug it into the
cigarette lighter socket in the
passenger compartment (refer to
page 97)
4. Make sure that the screw on the rear
of the pressure gauge 3 is tightened
down. Turn on the M Mobility system
(position I, refer to illustration) and
allow minutes to elapse, to let the
sealant flow in. It does not matter
afterward, what the tire's inflation
pressure is
5. Turn the sealant off.
Disconnect the connector hose from
the sealant container and the wheel
valve. Stow the M Mobility system in
the luggage compartment.
Distributing the sealantRight afterward, drive at least 1.2 miles
(2 km), so that the liquid sealant distrib-
utes evenly throughout the inside of the
tire.
Do not exceed a maximum speed
of 40 mph (60 km/h). If possible,
keep the vehicle speed above 10 mph
(20 km/h).
Stop in a suitable spot.<
