which then reverts to an emergency
default program allowing continued
operation at reduced power and
lower engine speeds.
Please have the system inspected at
your BMW center.
Displays after completion of tripAll of the malfunctions registered during
the trip appear consecutively when the
ignition key is turned to position 0.
The following displays will appear when
appropriate:
>"LIGHTS ON"
>"KEY IN IGNITION LOCK"
>"CHECK ENGINE OIL LEV"
Add engine oil at the next opportunity
(next stop to refuel). Refer to
page 142.
This display appears when you open
the driver's door after parking the
vehicle. A supplementary gong is also
heard.
Status messages remain available for a
period of approx. three minutes after
the display goes out and the key is
removed from the ignition. Press the
CHECK button 3. If there were multiple
reports, press the CHECK button
repeatedly to view them all in
sequence.
To check the Check ControlPress the CHECK button 3 with the
ignition key in position 2:
CHECK CONTROL OK appears in the
display.
No malfunctions are present in the
monitored systems.ComputerYou can find a description of the com-
puter on pages 88 and 93 as well as in
the "Owner's Manual for Onboard Com-
puter."
You can have the Check Control

Break-in proceduresTo ensure that your vehicle provides
maximum economy throughout a long
service life, we request that you
observe the following suggestions.Engine and differentialUp 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).
Comply with all official 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.
TiresOwing 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, you should drive with
extra care during the initial 200 miles
(300 km).
Comply with 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 com-
plete loss of traction, vehicle control
and braking effectiveness. Reduce your
speed on wet roads.<
Brake systemApprox. 300 miles (500 km) must
elapse before the brake pads and
rotors 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
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 applied.
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 instance Ð substan-
tially higher levels of pedal force will be
required to brake the vehicle.< ClutchThe clutch will also begin to function
optimally after about 300 miles
(500 km). Engage the gears carefully
during the break-in period.

Brake systemBrake fluid level If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the two brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and the vehicle may exhibit
a slight tendency to pull to one side
when the brakes are applied. Braking
distances may also be longer. Please
remember to adapt your driving style
accordingly.<
Disc brakesLimited vehicle use, extended periods
with the vehicle parked or in storage,
and operating conditions in which
braking is restricted to gentle, low-
pressure applications will all increase
the tendency for corrosion to form on
the rotors; this is often accompanied by
a simultaneous accumulation of con-
tamination on the brake pads. The pads
must exert a certain minimal level of
pressure against the rotors for the disc
brakes' inherent self-cleaning effect to
remain effective; the pressure available
under the above conditions may not
provide adequate cleansing.
If the brake rotors are corroded, they
will tend to respond to braking with a
pulsating effect that even extended
brake applications will fail to cure.
When driving in heavy rain and on wet
roads it is a good idea to apply light
pressure to the brake pedal every few
miles. Monitor traffic conditions to
ensure that this maneuver does not
pose a hazard to you or to other road
users. The heat generated in this pro-
cess helps dry the pads and rotors to
ensure that your brake system will
respond with undiminished efficiency
when you need it.When descending steep hills and
extended grades, downshift to a gear
that will allow you to continue safely
with only a minimal amount of braking.
By minimizing the loads placed on the
brake system, this strategy helps
ensure that optimal brake system
response will remain available at all
times.
Do not coast with the clutch
depressed or with the transmission
or selector lever in Neutral. Do not coast
with the engine switched off. The engine
provides no braking effect when the
clutch is depressed and there is no
power-assist for braking or steering
when the engine is not running.
Never allow floor mats, carpets or any
other objects to protrude into the area
around the accelerator, clutch and brake
pedals and obstruct their movement.<
Brake pads
For your own safety: use only
brake pads that BMW has
approved for your particular vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
