Engine oil thermometer
The engine oil temperature is between approx.
1607/706 and approx. 3407/1706 during
normal operation.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gage
Fuel tank capacity: approx. 18.5 US gallons/
70 liters, including the reserve capacity of
approx. 2.1 gallons/8 liters. You can find infor-
mation on refueling on page166.
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.
After the reserve quantity has been reached, a
message appears for a short time on the Con-
trol 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, as otherwise engine functions are not
ensured and damage can occur.<
Service requirements
The remaining distance to be driven and the
date for the next maintenance are briefly indi-
cated with the ignition key in position 2.
Your BMW Service Advisor will determine
your vehicle's current service require-
ments by reading out the data stored in the
master key.<
Additional information
You can view additional information on service
and maintenance procedures on the Control
Display.
Control Center, for principle details, refer to
page16.
1.Open the menu.
2.Select "Service" and press the controller.
3.Select "Service requirements" and press
the controller.
4.Select "Status" and press the controller.
The display shows a list of selected service and
maintenance procedures, as well as legally
mandated official inspections.

heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to
a level of performance which all passenger car
tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the
laboratory test wheel than the minimum
required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either sep-
arately or in combination, can cause heat
buildup and possible tire failure.<
RSC – run-flat tires
You will recognize run-flat tires by a circular
symbol containing the letters RSC on the side
of the tire, refer to page172.
M+S
Winter and all-season tires.
These have better winter properties than sum-
mer tires.
Tire condition
Inspect your tires frequently for tread wear,
signs of damage and foreign objects lodged in
the tread, and check the tread depth.
Minimum tread depth
The tread depth should not drop below 0.12 in/
3 mm, although, for example, European legisla-
tion only specifies a minimum tread depth of
0.063 in/1.6 mm.
At tread depths below 0.12 in/3 mm there is an
increased risk of high-speed hydroplaning,
even when only small amounts of water are
present on the road surface.
Winter tires noticeably loose their suitability for
winter use below a tread depth of 0.16 in/4 mm. New tires should be mounted in the interest of
safety.
Wear indicators at the tread-groove base, refer
to arrow, are distributed over the tire's circum-
ference and are marked on the side of the tire
with TWI – Tread Wear Indicator. If the indica-
tors are at the level of the profile, the legal per-
missible tread depth of 0.063 in/1.6 mm has
been reached.
Tire damage
Due to low-profile tires, please note that
wheels, tires and suspension parts are
more susceptible to road hazard and conse-
quential damages.
Unusual vibrations encountered during normal
vehicle operation can indicate tire failure or
some other vehicle defect. This can, for exam-
ple, be caused by driving over curbs. These
kinds of problems may also be signaled by other
changes in vehicle response, such as a strong
tendency to pull to the left or right.
In these cases reduce your speed immediately
and have the wheels and tires inspected imme-
diately. To do this, carefully drive to the next
BMW center or a specialized tire dealer which
works with personnel trained in accordance
with BMW specifications. Have the vehicle
towed to the workshop if necessary.
Tire damage can be extremely dangerous to
vehicle occupants and other road users.<
Unprofessional attempts by laymen to
service tires can lead to damage and acci-
dents. Have this work performed by skilled pro-
fessionals only. The technicians at your BMW
center will be glad to assist you with the
required professional knowledge and special-
ized equipment.<

OBD Socket
The Onboard Diagnostics OBD interface
socket is located on the left of the driver's side
under the instrument panel and under a cover.
The cover has the letters OBD on it.
The purpose of the OBD system is to ensure
proper operation of the emission control sys-
tem for the vehicle's lifetime. The system mon-
itors emission-related components and sys-
tems for deterioration and malfunction.
An illuminated indicator lamp informs
you of the need for service, not of the
need to stop the vehicle. However, the
systems should be checked by your BMW cen-
ter at the earliest possible opportunity.
Display of the previously described
malfunction on Canadian models.
Under certain conditions, the indicator
lamp will blink or flash. This indicates a rather
severe level of engine misfire. When this
occurs, you should reduce speed and consult
the nearest BMW center as soon as possible.
Severe engine misfire over only a short period
of time can seriously damage emissions control
components, especially the catalytic converter.
When the fuel filler cap is not properly
tightened, the OBD system can detect
the vapor leak and the indicator lamp will light
up. If the filler cap is subsequently tightened,
the indicator lamp should go out within a few
days.<
Event Data Recorders
Your vehicle may be equipped with one or more
sensing and diagnostic modules or a recording
device capable of recording or transmitting cer-
tain vehicle data or information. In addition, if
you have a Subscription Service Agreement for
the BMW Assist system, certain vehicle infor-
mation may be transmitted or recorded in order
to provide such services.
Care
Important information on care and maintenance
of your BMW is contained in the Caring for your
vehicle brochure.
