Functioning of brake system

Both circuits function independently. One
brake circuit operates the front and the other
the rear axle.
In the unlikely event of hydraulic failure of
one circuit, push the brake pedal down
firmly and hold it in that position. A
mechanical linkage activates the second
circuit, and you will be able to bring the
vehicle to a stop.
Failure of one brake circuit will impair the
braking capability resulting in an
increased stopping distance.
If one brake circuit has failed, the other will
still operate. However, you will notice an
increased pedal travel when you step on the

experience, bring your vehicle safely to a full

Before descending a steep grade, reduce

Brake wear
Our automobiles have excellent brakes, but
they are still subject to wear, depending on
how the brakes are used. Have the brake

The ABS system represents a major
contribution to the enhancement of active
safety in your vehicle. This system prevents
the wheels from locking in a panic stop on
almost all road surfaces.
With ABS system in your vehicle, the
following areas are enhanced:
Full steerability, vehicle remains steerable
under all braking forces.
Good directional control, no swerving
caused by locking of wheels under braking
conditions.
Excellent stopping distance, stopping
distances are usually reduced because
controlled braking is maximized.
Prevention of wheel lock up, no brake-

The crucial advantage of ABS system over a
conventional brake system is in the area of
maintaining directional control and
maneuverability of the car in emergency
situations, including panic braking in turns.
WARNING:
In spite of the improved handling afforded
by the ABS system, it still remains the
responsibility of the driver to adapt the
driving style to the prevailing road and
weather conditions, as well as, obeying
traffic laws. In no case, should the higher

in revolutions per minute (rpm).
The mark at the end of the scale indicates the
maximum permissible engine rpm. Before
reaching this area, the next higher gear
should be selected. Earlier shifting saves fuel.
Shift to the next lower gear when the engine
rpm drops below 1500 rpm.
The speed limiting governor prevents the
engine from being overrevved under load.
Boost Pressure Gauge
On the 944 Turbo there is a boost pressure
gauge in the lower part of the tachometer.
This instrument indicates the pressure in the
intake manifold.
With the ignition on and the engine stopped,
the indicated pressure corresponds to the
ambient air pressure (atmospheric pressure)
of approx. 1 bar.
Should an excessively high boost pressure
the ignition is cut off automatically.

CASIS
Computer Assisted Shift Indicator System

such as driving speed, engine rpm, engine
load and engine temperature.
When the CASIS arrow in the tachometer
lights up, it means the engine could operate
more economically. The light indicates that
a higher gear. The CASIS light will go out
taking your foot off the accelerator pedal or
the CASIS light is inoperative.
During maximum acceleration, the CASIS
arrow light will only light up at a point where
engine rpm is such that improved acceleration
gear. This means the CASIS arrow does not
indicate any set shift point, but that the
the way you drive. The arrow will light up at
the lowest speed range when cruising, and at
the highest speed range when accelerating
How to use CASIS
Drive your Porsche shifting as you normally
load range, the CASIS light will remind you to
shift into the next higher gear to keep the
lower fuel consumption.
You will get used to CASIS quickly and there
fore operate your Porsche with the CASIS
arrow light coming on only now and then.
WARNING
Use CASIS to your best advantage but
remember that traffic, road and weather

Check for possible leaks.
If the coolant level is normal, proceed to the

the coolant will heat up again. When the
needle enters the upper field, stop again and
let the engine cool down before you continue
driving.
Coolant system malfunctions should be
remedied by the nearest Porsche dealer, as
severe engine damage may occur.

Warning Light
The brake pad warning light comes on when

If the light stays on when the engine is
running or comes on while driving, the brake
pads are worn, excessively.
Do not continue to operate the vehicle but
have your Porsche dealer check and
replace the brake pads.

When the ignition is turned on the light will
come on for about 6 seconds to remind driver
and passenger to buckle up. See "Safety
