When you switch on the ignition, the
indicator lamp comes on briefly to indi-
cate that the system is operational.
If the indicator lamp comes on and
stays on, there are approx. 2.1 gallons
(8 liters) of fuel in the tank.
Tank volume: Page 166.
If the tilt of the vehicle varies, e.g.,
when you are driving in mountainous
areas, this may cause the needle to
fluctuate slightly.
a
Please refuel early, as driving
to the last drop of fuel can result in
damage to the engine and/or catalytic
converter.c

ate engine and vehicle speeds.RedIndicator lamp comes on, the warning

Switch off the engine immediately and
allow it to cool down.
Between the blue and red sectorsNormal operating range. It is not un-
usual for the needle to rise as far as the
edge of the red sector in response to
high outside temperatures or severe
operating conditions.

Coolant level with engine cold: up to
the KALT/COLD mark on the transpar-
ent coolant expansion tank.
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 corro-
sion. No other additives are required.
Replace the coolant every three years.
To add coolantWait until the engine cools before re-
moving the cap from the expansion
tank. Before unscrewing the cap, en-
sure that the needle on the temperature
gauge is in the blue sector to avoid
scalding.
dStart by turning the cap counter-
clockwise. Pause to allow any accu-
mulated pressure to escape, then
open.
dAdd coolant up to the KALT/COLD
mark. Excess coolant drains off
through the overßow line.a
Do not add coolant while the
engine is hot.
To avoid the possibility of damage later
on, never use anything other than
factory-approved nitrite and amino-free
long-term antifreeze and corrosion
protectant. Your authorized BMW
Retailer is familiar with the official
specifications.
Antifreeze with corrosion protectant is
toxic. Always store in original contain-
ers only, keeping them tightly closed.
Store well out of reach of children.
When disposing of it, observe the
applicable environmental protection
laws.Long-term antifreeze and corrosion
protectant contains the flammable
substance ethylene glycol. You should
therefore avoid spilling it on hot engine
components, as it could catch fire and
cause serious burns.c

mental protection laws when disposing

Never use spot remover, paint thinner,
solvents, gasoline etc. to remove spots
from the convertible top and from the
rear window, as these substances
destroy the rubber seals and lead to
leaks. Use only BMW-approved clean-
ers.
In addition to the advantage of being
extremely flexible, the rear window also
has the disadvantage of having a rela-
tively soft surface. For this reason, only
clean the rear window with a soft, anti-
static cloth or with BMW Convertible
Rear Window Cleaner.
If you wash the vehicle frequently in
brush car washes, and in particular in
those with hard brushes, faint scratches
in the rear window may result. With the
window replacement system you can
replace a heavily scratched window at a
relatively low price. Please contact your
authorized BMW Retailer for additional
information. b

Cleaning agents can contain sub-
stances that are dangerous or bad for
your health. Therefore always observe
the warnings and danger notices on the
package.
Open the doors or windows on your ve-
hicle when cleaning the interior.
Never clean your vehicle with solvents
or other materials not specifically in-
tended for this application.c
Hardtop:Please follow the instructions for car
care from page 131.If the vehicle is to be temporarily stored
for more than three months, have the
following maintenance performed by
your BMW Retailer:
1 Cleaning, preservation and retreat-
ment of the engine, engine compart-
ment, underbody, axles and
subassemblies in accordance with
the factory speciÞcations. Vehicle
washing with interior cleaning fol-
lowed by paint and chrome care.
Clean rubber seals of the hood, lug-
gage compartment lid and doors and
rub with either talcum powder or
glycerine oil.
2 Change engine oil and oil Þlter at
operating temperature. As an addi-
tional corrosion protection measure,
an anti-corrosive agent can be added
to the engine in accordance with the
manufacturer's instructions.
3 Check the coolant level and concen-
tration and top up if necessary.
4 Check the acid level in the battery
cells and add distilled water if neces-
sary.
5 Increase the tire inßation pressure to
50.9 psi (3.5 bar).
