while
the
engine is off.
the
brake booster pressure
re-
serve may
run low. lf the brake pressure,
in-
terlock
and
central warning lights come
on
after starting the engine, you should not
drive
off
until
the pressure necessary for
the
brake
booster and interlock control system has
built
up, and the warning lights
go
out"
lf
the warning buzzer sounds when the
warn-
ing light
is on,
the pressure
reserve is too
low.
lf the warning light
starts to blink after it lights,
this indicates a
defective
warning
switch.
When the pressure reserve is
too low, the
in-
terlock warning light
is
simultaneously
acti-
vated, and there is then no guarantee that
the
interlocks
will
function.
If the
pressure reserve
is
low
or
if a
brake
circuit
has
failed, greater braking pressure will
be
required and stopping distances
will
be
longer.
Consult
the
nearest authorized Porsche
dealer
immediately to have the condition corrected.
ffi
earking Brake Light
The
parking
brake light
will
be on when
the
ignition is on and the parking brake has
been
pulled up even slightly. The light is
a
warning
to release the parking brake before
driving the
car. The light does not indicate that the
brake
has been pulled up far enough
to
prevenT the
car from rolling. The light goes out only
when
the parking brake
is
fully
released.
Tachometer
The
first
red mark on the tachometer dial is
a
visual warning
of the maximum engine
speed.
A governor
interrupts the fuel supply
if
the
en-
gine
is
loaded above
this limit during
accel-
eration. Always
bear
in
mind the
maximum
change-down engine speeds belore selecting
a lower gear.
WARNING
Downshifting at
too high a speed can
cause
serious
damage
to your vehicles
engine.
