OverviewControlsMaintenanceRepairsDataIndex
Tire Pressure Monitor RDC*The conceptRDC monitors the tire pressures at all
four tires, even when the vehicle is
moving. The system provides an alert
whenever the inflation pressure drops
significantly below the specified pres-
sure in one or more tires.
In order for the system to learn the cor-
rect tire inflation pressure, check the
inflation pressures in all tires, refer to
the table on page 27 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the instru-
ment cluster or the Check Con-
trol will inform you if the tire
pressure is different from the learned
values.
To switch the system on1. Turn the ignition key to position 2, do
not start the engine
2. Maintain pressure on the button until
the yellow indicator lamp in the
instrument cluster comes on for sev-
eral seconds or the message Ð TIRE
PRESSURE SET Ð appears in the
Check Control
3. After you have driven for a few min-
utes, the RDC will import the current
inflation pressure in the tires as the
reference values which the system
will monitor.
You will only have to repeat this proce-
dure if the tire inflation pressure must
be corrected. Otherwise, the RDC func-
tions automatically when the ignition
key is in position 2, and thus operates
whenever the vehicle is driven.530de232
Loss of tire pressureIf, after a certain period of time, the
inflation pressure has gone down sig-
nificantly, which is normal for any tire,
the yellow indicator lamp comes on or
the message Ð CHECK TIRE PRES-
SURE Ð appears in the Check Control.
This alerts you that you should have the
tires inflated to the specified pressures
as soon as possible.
If you are prompted to check the
tire pressure shortly after a cor-
rection has been made, this indicates
that the corrected values were not
accurate. Please check the inflation
pressure again and make corrections
according to the inflation pressure
table. After that reactivate the system.<

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.

General driving notes
Antilock Brake System
Brake system
Brakes:
Do not drive with your foot resting
on the brake pedal. Even light but con-
sistent pedal pressure can lead to high
temperatures, brake wear and possibly
even brake failure.
Hydroplaning:
When driving on wet or slushy roads,
reduce vehicle speed. If you do not, a
wedge of water may form between the
tires and the road surface. This phe-
nomenon is referred to as hydroplaning
or aquaplaning. It is characterized by a
partial or complete loss of contact
between the tires and the road surface.
The ultimate results are loss of steering
and braking control.<
The conceptThe Antilock Brake System ABS keeps
the wheels from locking during braking,
thereby enhancing active driving safety.Braking with ABSIf you are in a situation that requires full
braking, you will exploit the full benefits
of the ABS system if you apply max-
imum pedal pressure Ð panic stop.
Pulsation at the brake pedal combined
with sounds from the hydraulic circuits
indicates to the driver that ABS is in its
active mode.
Brake fluid levelIf the brake fluid level is too low and
brake pedal travel has become longer,
there may be a defect in one of the two
brake system's hydraulic circuits.
Proceed to the nearest
BMW Sports Activity Vehicle
center. Here increased pressure on the
brake pedal may be required, and slight
pulling to the side and longer braking
distances may result. Please remember
to adapt your driving style accord-
ingly.<

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.

Winter tires Snow chains
*
Choosing the right tire BMW recommends winter tires Ð M+S
radial tires Ð for operation under
inclement winter driving conditions.
While so-called all-season tires with
M+S designation provide better winter
traction than summer tires with the load
ratings H, V, W, Y and ZR, they gener-
ally 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 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 Sports
Activity Vehicle 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
pressures Ñ and be sure to have the
wheel and tire assemblies balanced
every time you change the tires.
Only certain snow chains have been
tested by BMW and classified and
approved as safe. Consult your BMW
Sports Activity Vehicle center for
details. The use of narrow-link BMW
snow chains is approved only in pairs
on the rear wheels and only with the
following tire sizes.
BMW X5 4.6is: 255/55 R18
All other models: 235/65 R 17.
Comply with all manufacturer's safety
precautions when mounting the chains.
Do not exceed a maximum speed of
30 mph/50 km/h.

Changing a wheel9. Position the spare wheel. Secure
the wheel by turning at least two
lug bolts into opposite bolt holes
10. Screw in the remaining lug bolts.
Tighten all the bolts securely
11. Lower the jack and remove it from
beneath the vehicle
12. Tighten the lug bolts in a diagonal
pattern
13. Check and correct the tire inflation
pressure at the earliest opportunity.
Vehicles with Tire Pressure Monitor

*:
After mounting the spare wheel or
correcting the tire inflation pres-
sure, reactivate the system, refer to
page 97.
Protect valve stems and valves from dirt
using screw-on valve stem caps. Dirt in
the valve stems frequently leads to slow
leaks.The vehicle jack is designed for
changing wheels only. Do not
attempt to raise another vehicle model
with it or to raise any load of any kind.
To do so could cause accidents and
personal injury.
To ensure continued safety, have the
tightness of the lug bolts checked with
a calibrated lug wrench Ð torque speci-
fication: 101 lb-ft/140 Nm Ð at the
earliest opportunity.<
Store the wheel and the tools in the
order opposite that for removal.
Before removing the support rod,
be sure that the tailgate is held
down firmly. If you fail to do so, it could
retract sharply upward and cause per-
sonal injury and vehicle damage.
After you remove the rod, close the tail-
gate carefully. Continue to hold it firmly
until it is completely closed.<
If light-alloy wheels other than original
BMW light-alloy wheels have been
mounted, it may be necessary to use
different lug bolts for those wheels.
Replace the defective tire as soon as
possible and have the new wheel/tire
balanced. Driving with spare wheel
With certain wheel-and-tire com-
binations the size of the spare
wheel differs from that of the other
wheels. The spare wheel is equivalent
to these in all speed and load ranges.
However, to restore the original state,
the normal wheel should be remounted
as soon as possible.
When the spare wheel is mounted, the
maximum speed rating is 130 mph/
210 km/h.<
