Tachometer
The advance warning field, arrow1, and the red
warning field, arrow2, change depending on
the engine temperature. As the engine temper-
ature rises, the permissible engine speed also
increases. Avoid allowing the engine speed to
rise as far as the orange warning field whenever
possible.
Be sure to avoid engine speeds in the red warn-
ing field. At high revs in this range, the flow of
fuel is interrupted to protect the engine.
Coolant temperature
Should the coolant, and with it the engine
become too hot, a warning lamp lights up. In
addition, a message appears on the Control
Display.
Checking coolant level, refer to page211.

Engine oil thermometer
The general operating temperature lies
between 1757/806 and 2507/1206. Do
not exceed a value of approx. 2657/1306.
If the engine oil temperature is too high, the per-
missible engine speed, and with it the available
engine output is reduced.
Fuel gauge
Fuel tank capacity: approx. 18.5 US gal/
70 liters. You will find information on refueling
on page198.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
After the reserve quantity has been reached, a
message briefly appears on the Control Display;
the remaining range is shown in the computer.
Below a range of approx. 30 miles/50 km, the
message remains on the Control Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km, otherwise engine functions are not
ensured and damage can occur.<

Outside temperature warning
If the display drops to +377/+36, a signal
sounds and a warning lamp lights up. A mes-
sage appears on the Control Display. There is
an increased danger of ice.
Even at temperatures above +377/
+36 ice can form. Therefore, drive care-
fully, e.g. on bridges and sections of road in the
shade, otherwise there is an increased accident
risk.<
You can set the unit of measure 7 or 6 on the

86 ing driving. The tires are shown in green on the
Control Display.
If a flat tire is detected during resetting
and applying the tire inflation pressures,
all tires are shown in yellow on the Control Dis-
play. The message "Tire low!" is displayed.<
Message with low tire inflation
pressure
The warning lamp lights up yellow. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.If all four wheels are shown in yellow, iden-
tify the damaged tire on the vehicle.
3.Repairing flat tire with M Mobility System,
refer to page217, or replace the damaged
wheel or wheels, refer to Changing wheels*
on page219.
The spare tire
* is equipped with the necessary
TPM electronics and is also monitored after
mounting and after resetting the system.
Have the tire replaced by a BMW center or a
workshop informed on handling TPM which
works according to BMW repair procedures
with correspondingly trained personnel.
Malfunction
The yellow warning lamp flashes and
then lights up continuously. The tires
are shown in gray on the Control Dis-
play and a message is displayed. No flat tire can
be detected.
A message like this is displayed in the following
situations:
>In case of a malfunction;
have the system checked.
>If a wheel is mounted without TPM elec-
tronics>If TPM is temporarily interfered with by
other systems or devices which use the
same radio frequency.
Declaration according to NHTSA/
FMVSS 138 Tire Pressure Monitoring
Systems
Each tire, including the spare*, should be
checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire infla-
tion pressure label. If your vehicle has tires of a
different size than the size indicated on the
vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires. As an added safety fea-
ture, your vehicle has been equipped with a tire
pressure monitoring system, TPMS, that illumi-
nates a low tire pressure telltale when one or
more of your tires are significantly under-
inflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signif-
icantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Underinfla-
tion also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability. Please note that the TPMS is
not a substitute for proper tire maintenance,
and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has
not reached the level to trigger illumination of
the TPMS low tire pressure telltale.
The TPMS malfunction indicator is combined
with the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will flash
for approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle startups as
long as the malfunction exists. When the mal-
function indicator lights up, the system may not
be able to detect or signal low tire pressure as
intended. TPMS malfunctions may occur for a
variety of reasons, including the installation of
replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction

BMW M5 Engineering
V10 High Output Engine
With a 305 cu in/5 liter displacement, the high-
speed V10 engine generates a maximum out-
put of 373 kW and a maximum torque of
384 lb ft/520 Nm. Its spontaneous response
characteristics yield a very broad usable engine
speed range. At the maximum engine speed of
8250 rpm, the flow of fuel is interrupted in order
to protect the engine. Due to the powerful
engine dynamics, when the vehicle is at rest,
the maximum engine speed is limited to
7000 rpm.
Warming up
The emissions control system causes the
V10 high-output engine to have slightly
rougher running characteristics during its
warm-up phase.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the sys-
tem design.
For additional information of warming up, refer
to Tachometer on page66 and Engine oil tem-
perature on page67.
Compound brake
Your BMW M5 has a high-performance brake
s y s t em wi t h p e rf o ra t e d c o m p o u n d b r a k e r o t o r s .
Due to the special structural features of these
brake rotors, function noises occur during brak-
ing, but this has no effect on the performance,
operating safety, and stability of the brakes.
Braking correctly
In order to keep the brake system in optimum
condition, it is useful to put them under load at
regular intervals in accordance with the nature
of the vehicle.
Also refer to Corrosion on brake rotors on
page115.
Drive train
In your BMW M5, particular importance was
attached to the direct connection of the engine
to the drive system. Due to the torsionally rigid
design of the drive train, the transmission of the
torque is also audible, as is customary in a
sports car. As a result, load shifts can be dis-
tinctly audible. This does not in any way impair
the function or the service life of the compo-
nents.
