Tire Pressure Monitor (TPM)*The conceptTPM monitors the tire pressures at all
four tires even while the vehicle is mov-
ing. The system provides an alert when-
ever the inflation pressure drops signifi-
cantly below the specified pressure in
one or more tires.
This indicator lamp in the instru-
ment cluster informs you when
the tire pressure deviates from
the target values.
Initializing the systemInitializing is necessary to familiarize the
system with the correct inflation pres-
sures.
Repeat this process after tire replace-
ment, tire rotation or any changes in tire
inflation pressure.
1. Check the tire inflation pressures in
all the tires, comparing them with the
inflation pressure chart on page 25,
and adjust them if necessary
2. Turn the ignition key to position 2, do
not start the engine
3. Press the button long enough for the
yellow indicator lamp in the instru-
ment cluster to light up for a few sec-
onds
4. After a few minutes' driving time,
TPM adopts the current inflation
pressures in the tires as the refer-
ence values to be monitored.In the event of loss in inflation
pressureIf the inflation pressure has dropped
significantly over a long period of time,
which is normal for any tire, the yellow
indicator lamp will come on.
This alerts you to 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
valid. Please check the inflation pres-
sure again and make corrections
according to the inflation pressure
table. Then reinitialize the system. sure, the red warning lamp will come
on. This visual alert is accompanied by
an acoustic warning signal.

Washer fluidHeadlamp* and windshield
washer systemApproximate capacity is
5.6 US quarts/5.3 liters.
Fill with water and – if required – with a
washer antifreeze additive according to
manufacturer's recommendations.
We recommend that you mix the
washer fluid before adding it to
the reservoir.<
Antifreeze agents for the washer
fluid are highly flammable. For this
reason, keep them away from sources
of flame and store them only in original
containers, inaccessible to children.
Comply with the instructions on the
containers.<
Engine oilChecking the oil level1. Park the vehicle on a level surface
2. Switch the engine off after it has
reached normal operating tempera-
ture
3. After approx. 5 minutes, pull the dip-
stick out and wipe it off with a clean
lint-free cloth, paper towel, or similar
material
4. Carefully push the dipstick all the
way into the guide tube and pull it
out again
5. The oil level should be between the
two marks on the dipstick.
As with fuel economy, oil consumption
is directly influenced by your driving
style and vehicle operating conditions.
The oil volume between the two marks
on the dipstick corresponds to approx.
1.1 US quarts/1 liter. Do not fill beyond
the upper mark on the dipstick. Excess
oil will damage the engine.

138
Coolant
Do not add coolant to the cooling
system when the engine is hot. If
you attempt to do so, escaping coolant
can cause burns.
Antifreeze and anti-corrosion agents
are hazardous to health. You should
always store them in their closed origi-
nal containers and in a location which is
out of reach of children. Antifreeze and
anti-corrosion agents are inflammable.
For this reason, do not spill them on hot
engine parts. They could ignite and
cause serious burns. Comply with the
instructions on the containers.<
Checking the coolant level and
adding coolantCheck the coolant level when the
engine is cold, approx. 687/+206.
1. Open the cap for the expansion tank
by turning it slightly counterclock-
wise to allow accumulated pressure
to escape, then open
2. The coolant level is correct when the
upper end of the red float rod – see
arrow – is at least even with the
upper edge of the filler neck, but no
more than 3/4 in / 2 cm above – that
is, up to the second mark on the float
rod
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze with corrosion inhib-
itor.<

140Maintenance
The BMW Maintenance SystemThe BMW Maintenance System has
been designed as a reliable means of
providing maximum driving and operat-
ing safety – and as cost-effectively for
you as possible.
Please keep in mind that regular main-
tenance is not only necessary for the
safety of your vehicle, but also plays a
significant role in maintaining its resale
value.Service interval displayWhile conventional systems rely on
milage alone to determine when service
is due, the BMW Maintenance System
reflects the actual conditions under
which the vehicle is operated: some
miles are more strenuous than others.
From a maintenance point of view,
62,000 miles/100,000 km accumulated
in short-distance urban driving are not
the equivalent of the same distance
covered at moderate cruising speeds in
long-distance highway travel.
The BMW Maintenance System
includes the Engine Oil Service and
Inspections I and II.
This service strategy accurately reflects
your own vehicle's specific needs by
defining maintenance intervals accord-
ing to individual operating conditions.
Minimal use drivers – significantly fewer
than 6,200 miles/10,000 km annually –
should have the engine oil changed at
least every 2 years since oil deterio-
rates over time, regardless of use.Service and Warranty Information
Booklet for US models/Warranty
and Service Guide Booklet for
Canadian modelsFor additional information on required
maintenance intervals and procedures,
please refer to the Service and War-
ranty Information Booklet for US mod-
els or the Warranty and Service Guide
Booklet for Canadian models.As a precaution against corrosion, if
your vehicle is exposed to potential
damage from unimproved road sur-
faces we suggest that you have the
body checked for damage from stone
chips and gravel at the same time.
Have your BMW center perform
maintenance and repair.
Be sure that all maintenance work is
recorded in the Service and Warranty
Information Booklet for US models, or
in the Warranty and Service Guide
Booklet for Canadian models. These
entries confirm that your vehicle has
benefitted from regular maintenance,
and are also required for warranty
claims.<

141 Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust, some of its con-
stituents, and certain vehicle com-
ponents contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash your hands after hand-
ling.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by
washing thoroughly with soap and
water.<
OBD interface socketThe interface socket for onboard diag-
nostics is located on the left-hand side
of the driver's side, behind a specially
marked cover located beneath the
instrument panel. The cover has the let-
ters OBD on it.
This interface makes it possible to
access data on emissions-related com-
ponents using special equipment.
An illuminated indicator informs
you of the need for service, not
that you need to stop the vehi-
cle. However, the systems should be
checked by your BMW center at the
next opportunity.
If the indicator blinks or flashes, this
indicates a high level of engine misfire.
Reduce speed and contact the nearest
BMW center immediately. Severe

157 Giving and receiving assistance
Jump-startingWhen your battery is discharged you
can use two jumper cables to start your
vehicle with power from the battery in a
second vehicle. You can also use the
same method to help start another
vehicle. Only use jumper cables with
fully insulated handles on the terminal
clamps.
Do not touch high-voltage wiring
and cables on a running engine.
Contact with components carrying high
voltage can be harmful or fatal. Care-
fully observe the following instructions
to avoid personal injury and/or damage
to one or both vehicles.<
1. The battery in the support vehicle
must also be rated at 12 volts. This
information is provided on the battery
label
2. Stop the engine of the support vehi-
cle and switch off all electrical com-
ponents in both vehicles – except for
the hazard warning flashers of the
support vehicle
3. Make absolutely certain that there is
no contact between the bodywork of
the two vehicles – short circuit haz-
ard
4. The auxiliary jump-starting terminal
located in your BMW's engine com-
partment acts as the positive battery
terminal. The cover of this auxiliary
terminal is marked with a + sign.
Remove by pulling the tab – see
arrow 1.
Start by connecting the jumper cable
from the positive terminal of the dis-
charged battery to the positive termi-
nal of the support battery
5. Then connect the negative terminals
with the other jumper cable. First
connect one end to the negative bat-
tery terminal or to a suitable ground
on the support vehicle. Then connect
the other end to the negative battery
terminal or a suitable ground on the
vehicle being started.
Your BMW is equipped with a special
nut for this purpose – see arrow 2
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparks at the battery terminals
and pose an injury hazard.<
6. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle
speed
7. Start the engine of the other vehicle
as usual. If the first start attempt is
not successful, wait a few minutes
before another attempt in order to
allow the discharged battery to
recharge
8. Before disconnecting the jumper
cables, let the engines run for a few
minutes
9. Then disconnect the jumper cables
in reverse sequence.
Depending on the cause of the fault,
have the battery checked and
recharged by your BMW center.
