Red or yellow: continue to drive
cautiously
The red brake warning lamp
lights up together with the warn-
ing lamps for ABS and DSC/
xDrive. In addition, a warning
signal sounds:
ABS, DSC, HDC and xDrive
have failed. Drive may be being
exerted exclusively via the rear
axle. Have the system checked
as soon as possible.
For additional information, refer to
pages91, 92
Proceed cautiously and defen-
sively. When driving on poor
roads, avoid using full throttle or press-
ing the accelerator beyond the kick-
down point and also avoid forceful
braking or full braking. Otherwise, the
drive train may be damaged or acci-
dents can occur.<
If the brake warning lamp lights up in
yellow in the above-described combi-
nation, the EBV Electronic brake-force
distribution is still available.

The concept The Flat Tire Monitor keeps track of the
inflation pressures in the four fitted tires
as you drive. The system provides an
alert whenever the inflation pressure in
one tire drops significantly in relation to
the pressure in another tire.
The check of the tire inflation pressure
is based on monitoring the relative
speeds of the wheels. A flat is detected
and reported on the basis of a deviation
in certain speed ratios.Functional requirementTo ensure reliable operation, the sys-
tem should have been initialized with
the correct tire inflation pressure.
System limits
The Flat Tire Monitor cannot indi-
cate sudden severe tire damage
caused by outside factors and does not
detect a natural, even pressure drop in
all four tires.<
In the following situations, the system
could be delayed or malfunction:
>When driving on snow-covered or
slippery road surfaces
>In the case of performance-oriented
driving: slip in the drive wheels, high
lateral acceleration
>False alarms and undetected loss of
pressure may occur when you are
driving with snow chains fitted.

Flat Tire MonitorInitializing system
Perform the initialization immedi-
ately every time you correct the
inflation pressure, change a tire or
change a wheel or all wheels. The vehi-
cle must be driven during initialization.<
1. Start the engine, but do not begin to
drive immediately.
2. Press the button until the yellow indi-
cator lamp in the instrument cluster
lights up for a few seconds.
3. Begin driving.
530de419
It takes a few minutes of driving before
the Flat Tire Monitor can detect and
report a flat tire.
When driving with snow chains,
do not initialize the system.<
Indication of a flat tire
The warning lamp lights up yel-
low. There is a flat tire or exten-
sive inflation pressure loss.
1. Reduce speed and stop the vehicle
carefully. Avoid sudden braking and
steering maneuvers
2. Identify damaged tire
If identification is not possible,
contact your BMW Sports
Activity Vehicle center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 165.

General driving notesClosing liftgate/tailgate
Operate the vehicle only when the
tailgate and liftgate are completely
closed. Otherwise, exhaust fumes
could enter into the passenger com-
partment.<
However, if special circumstances
should make it absolutely necessary to
operate the vehicle with the liftgate/tail-
gate open:
1. Close all windows and the panorama
glass roof
2. Increase the air supply for the air
conditioner or automatic climate
control to a high level, refer to
page105 or109.
Hot exhaust system
Extreme temperatures occur on
the exhaust system on any vehi-
cle. Do not remove the heat shields
installed adjacent to it, and never apply
undercoating to them. When driving,
standing at idle and while parking, take
care to avoid possible contact between
a hot exhaust system and any highly
flammable materials such as hay,
leaves, grass etc. Otherwise, there is a
danger of ignition and fire, with the risk
of serious injuries and damage.<
Mobile communications devices
in vehicle
BMW advises against using
mobile communications devices
such as mobile phones inside the vehi-
cle unless they are directly connected
to the external antenna. Otherwise, it is
impossible to prevent a mutual interfer-
ence of the vehicle electronics with the
mobile phone device. Also, there is no
guarantee that the radiation generated
by the transmission will be conveyed
out from the interior of the vehicle.<
When vehicle is parked Condensation forms in the air condi-
tioner system during operation and then
exits under the vehicle. Traces of water
on the ground are therefore normal.Brakes
Do not drive with your foot resting
on the brake pedal. Even light but
consistent pedal pressure can lead to
excessively high temperatures, brake
wear and possibly even brake failure.<
Road hazards
If road hazards, obstacles or curbs
are unavoidable, only drive over
them very slowly and carefully, other-
wise the wheels and suspension parts,
especially on vehicles fitted with low
profile tires, can be damaged.<
For more information on wheels and
tires, refer to page146.
Before driving into a car washFold in the exterior mirrors, refer to
page53, otherwise they could be dam-
aged due to the width of the vehicle.Hydroplaning
When driving on wet or slushy
roads, reduce road speed. If you
do not, a wedge of water can form
between tires and road surface. This
state can cause a partial or total loss
of contact with the road surface, of
braking control and of control over the
vehicle.<

Information for your safety The condition of the tires and the main-
tenance of the specified tire pressure
are crucial not only to the tire's service
life, but also to driving comfort and
most importantly, driving safety. Checking pressureOnly 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 spare wheel: 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 condition that can not
only compromise your vehicle's driving
stability, but also lead to tire damage
and the risk of an accident. Do not drive
with deflated, i.e. flat, tires. A flat tire
will seriously impairs your vehicle's
handling and braking response.
Attempts to drive on a flat tire can lead
to loss of control over the vehicle.<
After correcting the inflation pres-
sure(s), always reinitialize the Flat
Tire Monitor, refer to page99.<
Inflation pressures for factory-
installed tiresThe tire inflation pressure specifications
for your factory-installed tires at ambi-
ent temperature are listed on the edge
of the driver's door and can be con-
sulted when the door is open.Inflation pressuresThe tire pressure tables in the following
pages give all of the pressure specifica-
tions for the tire sizes indicated at ambi-
ent temperature.
The inflation pressures apply to
the tire sizes and tire brands
respectively approved and recom-
mended by BMW; a list of these is avail-
able from your BMW Sports Activity
Vehicle center.<530de225
Tire inflation pressure

142n
Tire inflation pressureFor correct identification of the right tire
inflation pressure for your tires, observe
the following:
>Tire sizes for your vehicle
>Load conditions
>Maximum allowable driving speed
Tire inflation pressures for driving up to
100mph or 160km/h:
For normal driving up to 100 mph or
160 km/h adjust pressures to the
respective tire inflation pressures listed
on the following page in the traveling
speeds column for normal driving at
spe eds up to a m axim um o f 10 0 m p h or
160 km/h to achieve optimum driving
comfort.
The permissible top speed for
these tire inflation pressures is
100mph or 160km/h. Do not exceed
this speed, as otherwise tire damage
and accidents may result.<
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, please observe, and, if nec-
essary, adjust tire pressures for speeds
exceeding 100 mph or 160 km/h from
the relevant table on the following
pages. Otherwise tire damage and acci-
dents could occur.<

Tire identification marks Wheel/tire condition 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 speci-
fied government test surfaces 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, cornering, hydro-
planing, or peak traction characteris-
tics.< TemperatureThe temperature grades are A, the
highest, B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions 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 tem-
perature can lead to a sudden flat tire.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal
Motor Vehicle 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 separately or
in combination, can cause heat buildup
and possible a tire failure.< M+SWinter and all-season tires.
These have better winter properties
than summer tires.
Wheel/tire damage Inspect your wheels and tires frequently
for tread wear, signs of damage and for
foreign objects lodged in the tread.
Check the tread pattern depth.
Please note that low-profile tires
make your wheels, tires and sus-
pension parts more susceptible to road
hazard and consequential damages.
Unusual vibrations encountered during
normal vehicle operation can indicate
tire failure or some other vehicle mal-
function. This can, for example, be
caused by driving over curbs. This is
also true for irregularities in the vehi-
cle's handling characteristics, such as a
pronounced tendency to pull to the left
or right. Should this occur, respond by
immediately reducing your speed.
Carefully proceed – or have your vehicle
towed – to the nearest BMW Sports
Activity Vehicle center or tire dealer to
have the wheels or tires inspected.
Tire damage, extending to sudden and
complete loss of pressure in extreme
cases, can pose a potentially lethal
safety hazard for the vehicle's occu-
pants and other road users alike.<
