Tire inflation pressures The specified inflation pressures are 
provided on a sticker attached to the 
B-pillar and visible with the driver's 
door open.Checking tire pressuresAll pressures are specified in the stan-
dard units of pressure for your country, 
psi or kilopascal, and apply to cold tires 
(tires at ambient temperature, refer to 
tire pressure table on the following 
page).
Vehicles with Tire Pressure Monitor 
(RDC)/Flat Tire Monitor:
After correcting the inflation pressures, 
reactivate the system, refer to 
pages 78, 80.
Another instruction plate regarding 
inflation pressures on the door pillar 
indicates which system is equipped on 
your vehicle.
Check the tire pressures on a 
regular basis Ð at least twice a 
month Ð and before every extended 
journey. Otherwise, incorrect tire pres-
sure can lead to driving instability, tire 
damage and accidents.
Remember to check the inflation pres-
sure in the space-saver or standard 
spare tire.
 
Inflate the spare tire to the highest infla-
tion pressure of any tire on your 
vehicle.<
Comply with tire approval 
specificationsThe 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 that 
not only meet US standards, but also 
European standards. We recommend 
the exclusive use of BMW approved 
tires.

Tire Pressure Monitor (RDC)
*
The conceptRDC monitors the tire pressures at all 
four wheels while the vehicle is moving. 
The system provides an alert whenever 
the inflation pressure drops significantly 
below the specified pressure in one or 
more tires.
In order for the system to learn the 
correct tire inflation pressure, check the 
inflation pressure in all tires according 
to the inflation pressure table on 
page 25 and make corrections as 
necessary. Then activate the system. 
This indicator lamp in the instru-
ment cluster will inform you if 
the tire pressure is not correct.
To activate the system1. Turn ignition key to position 2 (do not 
start the engine)
2. Press the button long enough for the 
yellow indicator lamp in the instru-
ment cluster to light up for a few 
seconds
3. After a few minutes driving time, the 
RDC adopts the current pressure 
levels as the reference, and from that 
point on, can detect and report a flat 
tire.
You will only have to repeat this proce-
dure following a correction of the tire 
inflation pressure. Otherwise, RDC 
functions automatically when the igni-
tion key is in position 2, and thus oper-
ates whenever the vehicle is driven.
In the event of loss in inflation 
pressureIf the inflation pressure has dropped 
significantly over a long period of time 
(which is normal for any tire), the yellow 
indicator lamp will come on.
This alerts you to have the tires inflated 
to the specified pressures as soon as 
possible.
If you are prompted to check the 
tire pressure shortly after a 
correction has been made, this indi-
cates that the corrected values were 
not accurate. Please check the inflation 
pressure again and make corrections 
according to the inflation pressure 
table. Then activate the system once 
again.<

In the event of a flat tireIf there is a tire failure with loss of pres-
sure, the indicator lamp comes on with 
a red lamp. In addition, an acoustic 
signal is sounded.
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 
wheel and flat tire.
The space-saver spare tire is 
provided for temporary use only in 
the case of a tire failure. It does not 
have RDC electronics and is not moni-
tored. The spare tire
 that has the same 
dimensions as the tires already 
mounted on the vehicle is equipped 
with the necessary RDC electronics 
and will be also monitored once the 
tires have been mounted and the 
system activated.<
RDC cannot alert you to severe 
and sudden tire damage caused 
by external factors.<
Have the tires changed by your 
BMW center.
Your BMW center has the information 
needed for working with RDC and is 
equipped with the necessary special 
tools.<
System interferenceLocal devices using the same radio 
frequency can interfere with RDC.
The yellow indicator lamp will come on 
during the malfunction. 
The indicator lamp also comes on
>in the event of a system fault 
>if a wheel is mounted without the 
appropriate electronics 
>if, in addition to the spare tire, addi-
tional wheels with RDC electronics 
are on board.
Please contact your BMW center for 
additional information.

Flat Tire Monitor
*
The conceptAs you drive, the Flat Tire Monitor 
keeps track of pressure levels in all four 
tires in order to detect and warn of any 
substantial pressure loss. 
The system actually detects pressure 
loss by monitoring differences in the 
relative speeds of the four wheels. It 
interprets variations outside specified 
limits as severe pressure loss, and then 
responds by generating a warning.
To initialize 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 adjusting the 
inflation pressure and letting the system 
"learn" the correct pressures.
1. Check the tire inflation pressure in all 
the tires, comparing them with the 
inflation pressure table on page 25, 
and correct 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 driving time, the 
Flat Tire Monitor adopts the current 
pressure levels as the reference, and 
from that point on, can detect and 
report a flat tire.

Flat Tire Monitor
*
Activate/deactivate the systemThe Flat Tire Monitor automatically 
assumes operation whenever you turn 
the ignition key to position 2. Unless 
manually deactivated, it is always on 
during normal vehicle operation.
To deactivate the system: press the 
button, the yellow indicator lamp comes 
on.
To activate the system: press the 
button again, the indicator lamp goes 
out.
You should deactivate the system 
before driving with snow chains, as the 
chains can generate spurious warnings 
and/or prevent the system from 
detecting actual pressure loss. 
In the event of a flat tire
The red warning lamp in the 
instrument cluster lights up to 
warn of pressure loss and tire 
failure. This visual alert is accompanied 
by an acoustic warning signal. Reduce 
your speed immediately, and steer and 
brake gently as you bring the vehicle to 
a stop. 
To reset the warning lamp: after 
replacing the flat tire you will need to 
reset the red warning lamp manually: 
maintain pressure on the Flat Tire 
Monitor button until the warning lamp 
goes out. Then reinitialize the system.
The Flat Tire Monitor cannot 
provide you with advance warning 
of sudden and severe tire damage 
caused by external factors.
The system also does not detect the 
gradual and minor loss of pressure that 
all tires display over extended periods 
of time.<
Check the tire inflation pressures 
on a regular basis, correcting 
them as necessary, refer to page 24.
The system may respond to operation 
on slippery or snow-covered road 
surfaces with false warnings or delays 
in detecting actual pressure loss.
Performance-oriented driving (slip at 
the drive wheels, high rates of lateral 
acceleration) can also increase the time 
that the Flat Tire Monitor requires to 
detect a flat tire.<
System malfunctionsThe yellow indicator lamp in the instru-
ment cluster lights up and remains on 
until the problem is corrected.
Please refer the problem to your BMW 
center.

To ensure that your vehicle provides 
maximum economy throughout a long 
service life, we request that you 
observe the following information. 
Engine and differentialUp to 1,200 miles (2,000 km): 
Constantly vary both engine and vehicle 
speed, remembering not to exceed 
4,500 rpm or 100 mph (160 km/h) 
during this period.
Always obey all official speed limits.
Do not use full throttle, and avoid 
pressing the accelerator beyond the 
kickdown point during these initial 
miles.
You can then proceed to increase both 
engine and vehicle speed once the 
initial 1,200 miles (2,000 km) have 
elapsed.
You should also observe the same 
break-in procedures if the engine or 
differential is replaced later in the 
course of the vehicle's life.
TiresDue to technical factors associated 
with their manufacture, tires do not 
achieve their full traction potential until 
after an initial break-in period. We thus 
ask you to drive with extra care during 
the first 200 miles (300 km).
Always obey all official speed limits.
When the vehicle is operated on 
wet or slushy roads, a wedge of 
water may form between the tire and 
the road surface. This phenomenon is 
referred to as aquaplaning, or hydro-
planing, and can lead to partial or 
complete loss of traction, vehicle 
control and braking effectiveness. 
Reduce your speed on wet roads.
rotors achieve the optimal pad-surface 
and wear patterns required for trouble-
free operation and an extended service 
life later on.
To break-in the separate parking brake 
drums, apply the parking brake lightly 
when coasting to a standstill (at a traffic 
signal, for instance), provided that 
traffic conditions allow you to do so. 
To avoid corrosion, repeat this proce-
dure from time to time.
The brake lamps do not come on 
when the parking brake is 
engaged. 
Vacuum for the brake system servo unit 
on your BMW is available only when the 
engine is running. When you move the 
vehicle with the engine switched off Ð 
when towing, for example Ð substan-
tially higher levels of pedal force will be 
required to brake the vehicle.
operate at optimum efficiency. 
Remember to engage the clutch care-
fully during this initial period.
