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 closed original
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.<
Comply with the applicable envi-
ronmental laws regulating the dis-
posal of antifreeze agents with corro-
sion inhibitor.<
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 is at least
even with the upper edge of the filler
neck; see arrow. The end of the float
may stick out by a maximum of
3/4 in / 2 cm – that is, up to the sec-
ond mark on the float
3. If necessary, add coolant. If the cool-
ant is low, slowly add coolant until
the correct level is reached – do not
overfill.
Brake fluidIndicator lamp
The brake warning lamp comes
on when the parking brake is
not engaged: the brake fluid
level is too low, refer to page 18.
Brake warning lamp for Cana-
dian models.
Adding brake fluidFor adding brake fluid or for determin-
ing and correcting the cause of brake
fluid loss, consult your BMW center.
Your BMW center is familiar with the
specifications for factory-approved
brake fluids – DOT 4.
Brake fluid loss results in extended
pedal travel. Refer to the information on
page 122.

136Maintenance
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 as
possible for you.
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 the resale
value of the vehicle.
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 – those who drive
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.

138Laws and regulations
California Proposition 65 warningCalifornia laws require us to state the
following warning:
Engine exhaust and a wide variety
of automobile components and
parts, including components found in
the interior furnishings in a vehicle, con-
tain 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 com-
ponent 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
earliest possible 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

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. support vehicle has 12 volts and
approximately the same capacity –
measured in Ah. This information is
provided on the battery
2. Stop the engine of the support vehi-
cle
3. Switch off all electrical components
in both vehicles.
Make absolutely certain that there
is no contact between the body-
work of the two vehicles. Otherwise
there is a short circuit hazard.<
Connecting the jumper cables
Always adhere to this sequence
when connecting jumper cables;
failure to observe this procedure can
lead to sparking and pose an injury haz-
ard.<
The auxiliary jump-starting terminal
located in your BMW's engine compart-
ment acts as the positive battery termi-
nal. Refer to the engine compartment
overview on page 130. The cover of this
auxiliary terminal is marked with a +.
1. Open the cover of the BMW auxiliary
jump-starting terminal. Do so by pull-
ing the tab – see arrow 1
2. Connect one terminal clamp of the
plus/+ jumper cable to the positive
terminal of the battery or to an auxil-
iary jump-starting terminal of the
support vehicle
3. Connect the second terminal clamp
of the plus/+ jumper cable to the
positive terminal of the battery or to
an auxiliary jump-starting terminal of
the vehicle to be started
4. Your BMW is equipped with a special
nut – see arrow 2 – to serve as the
ground or negative terminal.
Attach a terminal clamp of the
minus/– jumper cable to the negative
terminal of the support vehicle's bat-
tery or to a suitable ground on its
engine or bodywork
5. Attach the second terminal clamp of
the minus/– jumper cable to the neg-
ative terminal of the battery or to a
suitable ground on the engine or
bodywork of the vehicle to be
started.Starting the engine1. Start the engine of the support vehi-
cle and let it run for several minutes
at a slightly elevated engine idle
speed

2. Start the engine of the other vehicle
as usual.
If the first start attempt is not suc-
cessful, wait a few minutes before
another attempt in order to allow the
discharged battery to recharge
3. Allow the engines to run for several
minutes
4. Disconnect the jumper cables in
reverse sequence.
Depending on the cause of the fault,
have the battery checked and
recharged by your BMW center.
Do not use spray starter fluids to
start the engine.<
Towing the vehicle
Always observe all applicable
towing laws and regulations.<
Towing with a commercial tow
truck>Use wheel lift or flat bed carrier
>Do not tow with sling-type equip-
ment.
Never allow passengers to ride in
a towed vehicle for any reason.
Never attach tie-down hooks, chains,
straps, or tow hooks to tie rods, control
arms, or any other part of the vehicle
suspension, as severe damage to these
components will occur, possibly lead-
ing to accidents.<
