Oil Pressure Gauge
Engine
oil
pressure
is
shown in
bars.
At
5.000 rpm,
with the
engine at
normal
operating temperature (approx. gO"C
/
194"F),
the pressure
should be approx.4
bar. A slight
drop in oil pressure is
normal
under certain operating condjtions such
as
prolonged
highway driving in hot
weather.
36
At idle speed,
with
the engine
oil
hot, the oil
pressure can
sink to
0.5
bar
- this
does
not
indicate
any loss of engine performance.
However, if the oil
pressure
drops
suddenly
while you are
driving, or
if the warning light
comes on, pull
off the road, stop the engine
and wait tor it to
cool
down. Check
the
engine oil
level.
lf
the oil
level is
normal,
contact the
nearest dealer.
Oil Pressure
Warning Light
The
oil
pressure
warning light
comes
on
when the
ignition
is turned on. lt should
go
out
when the
engine
is
started and
has
reached the correct oil
pressure.
lf
the
oil
pressure
warning light
does
not
light
up when turning the ignitjon
on, or if
jt
does nol go
out after starting the
engine,
contact your
Porsche dealer immediately.
lf
the
oil
pressure warning light
comes
on
while you are driving,
pull
olf
the road
and
stop the engine.
Check the oil
level
to
make
sure
you
have
enough oil.
lI
oil
level is correct and the oil
pressure
warning
light is still
on, do
not
drive
the
vehicle as
severe engine
damage
may result.
Contact
your
nearest
porsche
dealer Ior
assistance.
An
occasional brief flickering
ol
the
oil
pressure
warning
light
at
idle
speed
and
normal engine temperature is
no
cause for
concern
if the light goes
out
upon
accelera_
tion.
The
oil
p.essure warning
light is
not
an
indicalor for
low engine oil
level.
To check
lhe oil
level, always use the dlpstick.
Make il
a habit to have the
oll level checked
with every fuel
filllng,

Vottmetel
The voltmeter
shows the overall
condition oI
the charging
system.
The needle
should
nor-
mally stay in the 12*14 volt
range when the
engine is running. A temporary
drop below
12 volts
when starting the engine
is normal.
Alternator Warning Light
The alternator warning light
comes on when
the ignition is turned on.
lt
should
go
out
after
the engine
is started.
lI
the
alternator warning light does
nol light
up when turning the ignition
on, or
iI it does
nol go out after starting
the engine,
there
is
a
malfunction
in the electrical
system. l, this
is
the
case, contact your
Porsche dealer.
l,
the
alternator warning
light
comes
on
while you are dtiving,
pull
off the toad and
slop the enqine.
Check whether the Polyrib-belt
is
slipping or
broken.
The Potyrib-belt not only
drives the
alternator for
battery charging, but also the
air conditioner
compressor.
lf
the
light just
llickers
lighfly, the
potyrib
belt
may be loose
and
is
slipping.
The belt
should be tightened
or
replaced
before you continue drivinq,
