Tire Pressure Monitor RDC

Adaptive brake light
Flat tireIf there is a tire failure with a loss of
inflation pressure, the red indicator
lamp comes on or the message Ð TIRE
LOW/FLAT Ð appears in the Check
Control. In addition, an acoustic signal
sounds.
If this occurs, reduce vehicle speed
immediately and stop the vehicle in a
safe location. Avoid hard brake applica-
tions. Do not oversteer. Replace the flat
tire.
The spare tire which is available in
your vehicle as standard equip-
ment is equipped with the electronics
required for RDC and, following activa-
tion of the system, is also monitored
after it is mounted.<
RDC cannot alert you to severe
and sudden tire damage caused
by external factors.<
Have the tires changed at your
BMW Sports Activity Vehicle
center.
Your BMW Sports Activity Vehicle
center has the information needed for
working with RDC and is equipped with
the necessary special tools.<
System malfunctionDuring the period of the malfunction,
the yellow indicator lamp comes on or
the message Ð TIRECONTROL INAC-
TIVE Ð appears in the Check Control.
You will also see the same message
>in the event of a system malfunction
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics
are on board
>after installation of one or several
wheels with an electronics system
still unknown to the system.
It takes a few minutes to learn the
new wheel electronics ID numbers
after system activation. Only then can
RDC detect and report a flat tire.
Please contact your BMW Sports
Activity Vehicle center for additional
information.The adaptive brake light provides
drivers of following vehicles with an
indication of the intensity with which
the brakes are being applied in your
own vehicle.
The display occurs in two stages:
>Normal braking:
The brake light units within the tail
lamps and the high-mount brake
lamp integrated within the rear
spoiler both light up with normal
intensity
>Hard braking or braking with ABS
active:
The tail lamps also come on, lighting
up with the same intensity as the
brake lamps to provide a more con-
spicuous warning.

Cargo areaWhen it is extended, you can load the
cargo floor:
>With up to 990 Ibs/450 kg, distrib-
uted evenly across the entire surface
>With up to 330 Ibs/150 kg on the rear
edge.
Do not overload the cargo floor
when it is extended. If you do so,
it could cause damage.
When you slide the cargo floor back in,
do not grasp it on the bottom. If you do
so, there is a risk of personal injury.<
Raise the cargo floor For access to the spare wheel or other
stored items:
Swing the cargo floor up and secure it
with the rod, see detail.
If your vehicle has a partition net:
Take the bag with the partition net
out of the retainer, refer to page 122,
before you raise the cargo floor panel.
Otherwise, the bag could slide down-
ward.< 530de240

Information for your safety The factory-approved radial tires are
matched to the vehicle and have been
selected to provide optimum safety and
driving comfort on your vehicle when
used correctly.
It is not merely the tire's service life, but
also driving comfort and Ð above all else
Ð driving safety which 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 significantly influences the road-
holding ability of your BMW. Check tire
inflation pressures Ð including the spare
wheel Ð regularly, refer to page 26, 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 an
accident.<
Tire tread Ð Tire damage Inspect your tires frequently for tread
wear, signs of damage and for foreign
objects lodged in the tread. Check the
tread pattern depth.
Tread depth should not be allowed to
go below 0.12 in/3 mm, even though,
the legally specified minimum tread
depth, for example in Europe, is only
0.063 in/1.6 mm. Below a tread depth
of 0.12 in/3 mm there is an increased
risk of hydroplaning, even at relatively
moderate speeds and with only small
amounts of water on the road.
Tread wear indicators, refer to arrow,
are embedded around the tire circum-
ference in the base of the tire tread.
Their locations are indicated on the tire
sidewall with TWI Ð Tread Wear Indi-390de331
cator. At a tread depth of 0.063 in/
1.6 mm these indicators, signal that the
tires have reached the legally permis-
sible wear limit.
Do not drive on a deflated Ð flat Ð
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 leads to over-
heating and causes damage inside the
tires. The ultimate result can assume
the form of a sudden air loss.
Unusual vibrations encountered during
normal vehicle operation, e.g. caused
by contact with curbs, etc., can indicate
a flat tire or some other vehicle mal-
function. This is also true for irregulari-
ties in the vehicle's handling character-
istics, such as a pronounced tendency
to pull to the left or right. Should this
occur, respond by immediately
reducing your speed.

Tire replacement 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 Car 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.<
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
Tire age BMW recommends the replacement of
all tires Ð i.e. also of the spare tire, inde-
pendently of actual wear Ð when the
tires are no more than 6 years old, even
if a tire life of 10 years is possible.
The date on which the tire was manu-
factured is indicated by the code on the
sidewall:
DOT ... 2602 indicates that the tire was
manufactured in week 26 of 2002.

Removal aid for the spare wheelBy using this device, you do not have to
lift the spare wheel out of the recess by
hand.
Its task is to help you to move the wheel
onto the tailgate, from where you can
easily lift it off.

2. Grasp the handle of the removal aid
behind the spare wheel with both
hands and pull upward over the
tailgate, refer to arrow 530de310
