Coolant temperature gauge Engine oil temperatureBlueThe 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.
Comes on while driving: the engine is
overheated. Switch off the engine
immediately and allow it to cool down.36mde752
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.
Checking coolant level: page 112.
During normal operation the engine oil
temperature is between 175 7 (80 6)
and 250 7 (120 6). During perfor-
mance-oriented driving, do not exceed
the maximum temperature of 265 7
(130 6).
Up to an oil temperature of 140 7
(60 6) an engine speed of 4,000 rpm
may not be exceeded.

Coolant Brake fluid Checking coolant levelThe correct coolant level when the
engine is cold (approx. +68 7/+20 6).
Unscrew the cap from the expansion
tank.
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 (refer to the arrow in the illustra-
tion), but no more than 0.8 in (2 cm)
above it – that is, up to the second mark
on the float (refer also to the schematic
diagram next to the filler neck).367de356
To add coolantWait until the engine cools before
removing the cap from the expansion
tank. The needle of the coolant temper-
ature gauge in the instrument cluster
must be located in the blue field; other-
wise, there is a danger of scalding.
1 Turn the cap slightly counterclock-
wise in order to allow accumulated
pressure to escape. Then open.
2 If the coolant is low, slowly add
coolant until the correct level is
reached – 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 regularly. Refer to
the Service and Warranty Information
Booklet (US models) or the Warranty
and Service Guide Booklet (Canadian
models).If the warning lamp for the brake
hydraulic system comes on:
The brake fluid level is too low.
Add brake fluid until the upper
mark ("MAX") is reached.
To eliminate the cause of the brake fluid
loss, please consult a BMW center. You
can also receive information concerning
approved brake fluids (DOT 4) there.
Brake fluid loss may result in extended
brake pedal travel. If this occurs, refer
to the notes on page 92.

Storing your vehicle
If you intend to store the vehicle
for longer than three months, have
the maintenance operations described
on this page performed.<
Preparation for storageHave the following operations
performed by your BMW center:
1 Clean and apply a rustproofing agent
or other treatment to the engine,
engine compartment, undercarriage,
axles and major components in
accordance with approved repair
procedures. Wash the vehicle, clean
the interior and treat painted and
chromed parts. Clean the rubber
seals around the hood, luggage
compartment and doors.
2 Change the engine oil and oil filter
with the engine at operating tempera-
ture. As an additional corrosion
protection measure, a corrosion
inhibitor can be added to the engine
in accordance with the manufac-
turer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the fluid level of the wind-
shield washer fluid reservoir; top up 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 vehicle for
storage1 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 room. Place the
transmission in 1st gear. Chock the
wheels to prevent the vehicle from
rolling if necessary. Do not apply the
parking brake.
3 Remove the battery, charge it
completely and store it in a cool (but
frost-free) room.
M roadster:
4 Remove the hardtop
* and store it
separately. Refer to page 97.
5 Close the convertible top.
During storageRecharge the battery every six months.
If it is not recharged, it will not be
serviceable. 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 141.
Then have Inspection I performed by
your BMW center, including a brake
fluid replacement if necessary. Refer to
the Service Manual.
