Fuel specifications Tire inflation pressureThe engine uses lead-free gasoline
only.
Required fuel:
>Premium Unleaded Gasoline,
min. 91 AKI
AKI = Anti Knock Index
Do not use leaded fuels. The use
of leaded fuels will cause perma-
nent damage to the system's oxygen
sensor and the catalytic converter.<
The inflation pressures are indicated on
a sticker attached to the B-pillar behind
the driver's door (visible with door
open).Check tire pressuresAll pressure specifications are indicated
in psi (kilopascal) for tires at ambient
temperature (refer also to the next
pages).
For vehicles with Tire Pressure Control
(RDC)
*:
After a correction of the tire inflation
pressure, reactivate the system. Refer
to page 103.
390de351
Check tire inflation pressures reg-
ularly – at least every two weeks
and before beginning a longer trip.
Incorrect tire pressure can lead to tire
damage and accidents.
Check the inflation pressure of the
spare tire also. Inflate the spare tire to
the highest inflation of any tire on your
vehicle.<
Comply with tire approval
specificationsThe inflation pressures in the table
apply to tires from BMW approved
manufacturers. Your BMW center is
familiar with these pressures. Higher
pressures may be specified for tires
from other manufacturers. You will find
a list of approved tires beginning on
page 156.
Your vehicle is equipped with tires that
meet US standards as well as European
standards. We recommend the exclu-
sive use of BMW approved tires.

ASC+T/DSC
*
Tire Pressure Control (RDC)
*
To reactivate the systemPress the button again; the indicator
lamp goes out.
The laws of physics cannot be
repealed, even with ASC+T/DSC.
An appropriate driving style always
remains the responsibility of the driver.
We therefore urge you to avoid using
the additional safety margin of the
system as an excuse for taking risks.<
For additional details concerning
ASC+T/DSC, please refer to the
chapter describing "Advanced
technology" on page 207.
The concept RDC monitors the tire pressures at all
four wheels, 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
correct tire inflation pressure, check the
inflation pressure in all tires. Refer to
the table of "Tire inflation pressures"
beginning on page 29 and make any
necessary corrections. Then activate
the system.
This indicator lamp in the in-
strument cluster or the Check
Control will inform you if the
tire pressure is not correct.
Activate the system1 Turn the ignition key to position 2 (do
not start the engine).
2 Press and hold the button (arrow) un-
til the yellow indicator lamp in the in-
strument cluster comes on for a few
seconds or the message "SET TIRE
PRESSURE" 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
target 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.390de320

Tire Pressure Control (RDC)
*
Loss of tire pressureIf, after a certain period of time, the air
pressure has gone down significantly
(which is normal for any tire), the yellow
indicator lamp comes on or the mes-
sage "CHECK TIRE PRESSURE" ap-
pears 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 ac-
curate. Please check the inflation pres-
sure again and make corrections ac-
cording to the inflation pressure table.<
Flat tireIf there is a tire failure with a loss of air
pressure, the red indicator lamp comes
on or the message "TIRE DEFECT" ap-
pears in the Check Control. In addition,
a gong sounds.
If this occurs, reduce vehicle speed im-
mediately and stop the vehicle in a safe
location. Avoid hard brake applications.
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 af-
ter it is mounted.<
The RDC cannot alert you to se-
vere and sudden tire damage
caused by external factors.<
Have the tires changed by your
authorized BMW center.
Your BMW center has the information
needed for working with RDC and is
equipped with the necessary special
tools.<
System interferenceDuring the period of the malfunction,
the yellow indicator lamp comes on
or the message "TIRECONTROL
INACTIVE" appears in the Check
Control.
You will also see the same message
>in the event of a system fault
>if a wheel is mounted without the
RDC electronics
>if, in addition to the spare tire,
additional wheels with RDC
electronics are on board.
Please contact your BMW center for
additional information.

140nBreak-in procedure
To ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you ob-
serve the following.
Engine and differential
Up to 1,200 miles (2,000 km):
Drive at varying engine speeds and
road speeds, but do not exceed
4,500 rpm and the following road
speeds during this initial period:
BMW 525i, 530i: 100 mph (160 km/h)
BMW 540i: 106 mph (170 km/h)
Obey your local and state maximum
speed limits.
Refrain from using full throttle and avoid
pressing the accelerator beyond the
kickdown point.
Once you have driven 1,200 miles
(2,000 km), engine and vehicle speeds
can gradually be increased.
You should also comply with these
break-in procedures if the engine or dif-
ferential is replaced later in the course
of the vehicle service life.
Tires
Due to technical factors associated
with their manufacture, tires do not
achieve their full traction potential until
an initial break-in period has elapsed
for this reason, drive with extra care
during the initial 200 miles (300 km).
Obey your local and state maximum
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 com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads. <
Brake system
Approximately 300 miles (500 km) must
elapse before the brake pads and ro-
tors achieve the optimal pad-surface
and wear patterns required for trouble-
free operation and long 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 traf-
fic conditions allow you to do so. To
avoid corrosion, repeat this procedure
from time to time.
The brake lamps do not come on
when the parking brake is applied.
Vacuum for the brake system servo unit
on your BMW is available only when the
engine is running. When you move the
car with the engine shut off – when
towing, for instance – substantially
higher levels of pedal force will be
required to brake the vehicle. <
Clutch
The clutch will also begin to function
optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.
