Coolant temperature gauge Service Interval Display BlueThe engine is still cold. Drive at
moderate engine and vehicle speeds.RedWhen you switch on the ignition, the
warning lamp comes on briefly to
confirm that the system is operational.
If the lamp comes on in the course of
normal vehicle operation, the engine
has overheated. Turn it off immediately
and let it cool down.520de031
Between the blue and red zonesNormal operating range. It is not
unusual for the needle to rise as far as
the edge of the red zone in response
to high outside temperatures or severe
operating conditions.
For checking coolant level, refer to
page 113.
Remaining distance before
serviceThe displays shown in the illustration
appear for a few seconds when the
ignition key is in position 1 or after the
engine is started.
The remaining distance in miles and the
next scheduled service will appear
together with the display OILSERVICE
or INSPECTION.
The computer bases its calculations for
the remaining distance on the previous
driving style.
A flashing display and a "Ð" in front of
the number indicate that service is past
due by the number of miles displayed.
Please contact your BMW center for an
appointment.520us006

Brake system Winter operationBrake fluid level
The brake warning lamp comes
on with the parking brake
released:
The brake fluid level in the
reservoir is too low, refer to
page 114.
If the brake fluid level is too low and
brake pedal travel has become notice-
ably longer, there may be a defect in
one of the brake system's hydraulic
circuits.
Proceed to the nearest BMW
center. Higher brake application
pressure may be necessary under these
conditions, and brake pedal travel may
be significantly longer. Please
remember to adapt your driving style
accordingly.<
Brake pads
The warning lamp for the brake
pads comes on:
The brake pads have reached
their minimum thickness. Proceed to
the nearest BMW center as soon as
possible to have the pads replaced.
For your own safety: use only
brake pads which BMW has
approved for your specific vehicle
model. BMW cannot evaluate non-
approved brake pads to determine if
they are suited for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<
Winter is often accompanied by rapid
changes in weather, requiring not only a
different driving style, but also certain
preparations to the vehicle itself to
ensure that your progress through the
winter months remains safe and
trouble-free. CoolantBe sure that the coolant mixture
contains the year-round ratio of 50:50
water and extended-duty antifreeze
with corrosion inhibitor. This mixture
provides protection against freezing
down to approx. Ð34 7 (Ð37 6).LocksBMW door lock deicer can be used to
free doors if frozen. This deicer also
contains lubricant.
After using the deicer, treatment with
BMW lock cylinder grease is recom-
mended.

Engine oil Coolant
Comply with the applicable envi-
ronmental laws regulating the
disposal of used oil.<
Recommendation: have the oil changed
by your BMW center only.
Continuous exposure to used oil
has caused cancer in laboratory
testing.
For this reason, thoroughly wash any
areas of skin that come into contact
with oil using soap and water.
Always store oils, grease, etc. so that
they are inaccessible to children, and
follow warning lables on containers.<
Do not add coolant to the coolant
system when the engine is hot,
since escaping coolant can cause
burns.
To avoid the possibility of damage later
on, never use anything other than
factory-approved, nitrite- and amino-
free, extended-duty antifreeze with
corrosion inhibitor. Your BMW center is
familiar with the official specifications.
Antifreeze and corrosion inhibitor is
hazardous to health. Always store in
tightly closed original containers kept
well out of the reach of children.
Extended-duty antifreeze with corro-
sion inhibitor contains the flammable
substance ethyleneÐglycol: never allow
the antifreeze to spill onto hot engine
components, as fire and serious
personal injury in the form of burns
could result.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of extended-duty antifreeze
with corrosion inhibitor.<
Checking coolant levelThe correct coolant level when the
engine is cold (approx. 687/206):
Up to the "MAX" mark on the translu-
cent expansion tank.520de156

114n
Coolant Brake fluidAdding coolant To guard against the possibility of
scalding injuries, always wait until the
engine cools (temperature gauge
needle in blue sector) before
unscrewing the cap on the expansion
tank.
1. Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open
2. Slowly add coolant until the correct
level is reached Ð do not overfill.
The coolant is a mixture of water and
extended-duty antifreeze with corrosion
inhibitor. Always maintain the
prescribed all-season 50:50 mixture
ratio for year-round protection against
internal corrosion. No other additives
are required.
Replace the coolant every three years.The brake warning lamp comes on and
the parking brake has been released:
The brake fluid is too low.
For adding brake fluid or for deter-
mining 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 can increase brake
pedal travel. For this type of situation,
refer to the notes on page 92.
520de157
Brake fluid is hygroscopic, that is,
it absorbs moisture from the air
over time.
In order to ensure the safety and reli-
ability of the brake system, have the
brake fluid changed every two years by
a BMW center. Refer also to the Service
and Warranty Information Booklet
(US models) or the Warranty and
Service Guide Booklet (Canadian
models). Brake fluid is toxic and attacks
the vehicle's paintwork. You should
always store it in its original container
and in a location that is inaccessible to
children.
Do not spill the fluid and do not fill the
brake fluid reservoir beyond the "MAX"
mark. The brake fluid could ignite upon
contact with hot engine parts and
cause serious burns.<
Comply with the applicable envi-
ronmental laws regulating the
disposal of brake fluid.<

Vehicle storage
If the vehicle is to be stored for
more than three months, ensure
that the following service operations
are carried out first.<
Preparations for storageHave your BMW center perform the
following procedures:
1. Clean and apply a rust proofing
agent or other treatment to the
engine, engine compartment, under-
carriage, axles and major compo-
nents in accordance with approved
repair procedures. Wash the vehicle,
clean the interior and treat painted
and chromed parts. Clean the
weather-stripping around the hood,
luggage compartment and doors
2. Change engine oil and oil filter at
operating temperature. As an addi-
tional corrosion protection measure,
an anticorrosive agent can be added
to the engine in accordance with the
manufacturer's instructions
3. Check the coolant level and concen-
tration and top off if necessary
4. Check the fluid level of the wind-
shield washer fluid reservoir; top off
if necessary
5. Fill the fuel tank completely to
prevent the formation of condensa-
tion
6. Increase the tire inflation pressure to
51 psi (350 kPa).Before parking the vehicle1. Dry the parking brake and footbrake
by brake applications to prevent the
brake discs and drums from
corroding
2. Park the vehicle in a covered, dry,
and well-ventilated area. Place the
transmission in first gear or, if neces-
sary, chock the wheels to prevent the
vehicle from rolling. Do not engage
the parking brake
3. Remove the battery, charge it
completely and store it in a cool (but
frost-free) room
4. Remove the hardtop and store it
separately, refer to page 96
5. Close the convertible top.
During storageRecharge a battery that has been taken
out of the vehicle every six months. If it
is not recharged, it will not be service-
able. Every time the battery is
discharged, especially over extended
periods, its service life is reduced.Removing the vehicle from
storageRecharge the battery if the "Magic Eye"
turns black, refer to page 138.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement, if necessary. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).
