Indicator and warning lamps

Technology that monitors itself

Indicator and warning lamps that are
identified by

●

are tested for proper
functioning whenever the ignition key is
turned. They each light up once for dif-
ferent periods of time.
If a fault should occur in one of these
systems, the corresponding lamp does
not go out after the engine is started, or
it lights up while the vehicle is moving.
You will see how to react in the follow-
ing section.

Red: stop immediately

Battery charge current

●

The battery is no longer being
charged. Indicates a defective
alternator drive belt or a problem with
the alternator's charge circuit. please
contact the nearest BMW center.
If the drive belt is defective, stop
and switch off the engine immedi-
ately to prevent overheating and seri-
ous engine damage. If the drive belt is
defective, increased steering effort is
also required.

<

Engine oil pressure

●

The engine oil pressure is too
low. Stop the vehicle immedi-
ately and switch off the engine. It is not
possible to continue driving. Please
contact the nearest BMW center.
Do not continue driving, as the
engine could sustain serious dam-
age from inadequate lubrication.

DSC has been switched off with the
button; DTC is operational.
If there is a malfunction, have the sys-
tem checked as soon as possible.
Additional information beginning on
page 91.

Under these special circumstances
traction is increased by deactivating the
control systems that enhance traction
under normal conditions.Deactivating the DSC and the
DTCPress the DSC button as long as you
need to until the indicator lamp and the
yellow brake warning lamp light up, but
no more than 10 seconds.
The systems for enhancing stability and
traction are deactivated, and there is no
active braking intervention or torque
control.
To maintain vehicle stability,
always drive with the DSC acti-
vated whenever possible. or the indicator lamps will go out. DTC
is deactivated.
The laws of physics cannot be
repealed even with DSC.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 sys-
tem as an excuse for taking risks.
Whenever the DTC is activated, the
DSC is switched off and performs minor
stabilizing intervention.
Do not make any modifications to the
DSC system. Allow only authorized
technicians to perform service proce-
dures on the DSC.<
Flat Tire Monitor*The conceptAs you drive, the Flat Tire Monitor
keeps track of pressure levels in all four
tires. The system alerts you whenever
the inflation pressure of a tire falls sig-
nificantly below the pressure of another
tire.
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.Functional requirementsIn order for the Flat Tire Monitor to learn
the correct tire inflation pressure,
please do the following:
1. Check the tire inflation pressures in
all tires
2. Compare them with the tire inflation
pressure table, refer to page 130,
and correct them if necessary
3. Initialize the system.

System limitations
The Flat Tire Monitor cannot pro-
vide you with advance warning of
sudden and severe tire damage caused
by external factors and does not detect
the balanced and very gradual pressure
loss that takes place in all four tires
over an extended period of time.<
On the other hand, the following situa-
tions can lead to a delayed detection of
pressure loss and even to the system
not functioning:
>Driving on snow-covered or slippery
roads
>Performance-oriented driving: slip at
the drive wheels, high levels of lateral
acceleration
>When driving with snow chains, false
warnings and undetected pressure
losses may occur
>When driving with a space-saver
spare tire, the Flat Tire Monitor can-
not function.
Initializing the system
Each time you correct the pres-
sure in a tire, or change a wheel or
tire, reinitialize the system immediately
afterwards. This requires a bit of driv-
ing.<
1. Before driving off, start the engine
but do not start driving
2. Press the button as long as you need
to, but no more than 10 seconds,
until the indicator lamp in the instru-
ment cluster lights up in yellow for a
few seconds
3. Drive off.
It takes a few minutes before the Flat
Tire Monitor can detect a flat tire and
issue a warning.
When driving with snow chains or
a space-saver spare tire, do not
initialize the system.<
Flat tire
The indicator lamp in the instru-
ment cluster lights up red. This
visual alert is accompanied by
an acoustic warning signal.
1. Carefully reduce speed and come to
a stop. Avoid sudden braking and
steering maneuvers
2. Determine which wheel is damaged
If this cannot be determined, con-
tact your BMW center.<
3. Replace the damaged wheel, refer to
Changing a wheel on page 157.
After replacing the damaged tire, initial-
ize the system.
Vehicles with Run Flat tires:
1. Carefully reduce your speed to under
50 mph / 80 km/h. Avoid sudden
braking and steering maneuvers. Do
not exceed a speed of 50 mph /
80 km/h

Because the sides of Run Flat
tires are reinforced, a drop in infla-
tion pressure usually cannot be
detected from the outside, refer to Run
Flat tires, page 135.<
2. To continue driving, follow the
instructions under Driving with a
damaged tire on page 135.
System malfunction
The indicator lamp in the instru-
ment cluster lights up yellow.
The Flat Tire Monitor is malfunc-
tioning or out of order. Please refer the
problem to your BMW center.
Brake force displayBrake force display indicates to the
road users behind you how hard you
are braking.
>Normal braking: the brake lamps
among the rear lamps and the center
brake lamp light up
>Hard braking or braking with ABS: in
addition, the illuminated rear lamp
surface is extended, refer to the pic-
ture.

130Wheels and tires
Tire inflation pressureInformation for your safetyIt is not merely the tire's service life, but
also driving comfort and, above all else,
driving safety that depend on the condi-
tion of the tires and the maintenance of
the specified tire inflation pressure.
Check tire inflation pressures on a
regular basis and correct them, if
necessary, including the compact
wheel: at least twice a month and
before beginning a longer trip. If this is
not done, incorrect tire pressures can
cause driving instability and tire dam-
age, ultimately resulting in accidents.
Do not drive with a pressureless, i.e.
flat, tire, unless your vehicle is
equipped with Run Flat tires. A flat tire
greatly impairs steering and braking
response, and can lead to complete
loss of control over the vehicle. of cold tires. This means after driving a
maximum of 1.25 miles/2 km or after
the vehicle has been parked for at least
2 hours. Warm tires have higher infla-
tion pressures.
After correcting the tire inflation pres-
sure, reinitialize the Flat Tire Monitor,
refer to page 93.
Inflation pressures for original
tiresTire pressures for the standard tires of
your vehicle are shown on the driver's
door post, visible when the door is
open.
The inflation pressures apply to BMW-
approved tire sizes and recommended
tire brands. Your BMW center will be
glad to supply this information.Inflation pressures for other tire
sizesThe following tire pressure table shows
all tire pressures for the given tire sizes
at ambient temperature.
