automatic speed control allows you to maintain a constant cruising speed of
30 mph (50 km/h) or higher, without actuating the accelerator pedal. Any manual operation, such as
accelerating, gearshifting or braking can be done independent of the
automatic speed control. The
spring loaded control lever operating the automatic speed control is located
just below the wiper/washer lever. While driving with the automatic speed control set (at speeds above 30 mph or 50 km/h), do not bring shift lever into the Neutral position as excessive engine rpm will result. To operate the automatic
speed control Accelerate
to the desired cruising speed, push lever toward instrument cluster and
release. This sets the cruising
speed and stores it in a memory. After
a second or two, automatic speed control will take over, and you can remove
your foot from the accelerator pedal.
The set cruising speed will be maintained automatically. WARNING Do
not use the cruise control when it may be unsafe to keep the car at a constant
speed. For example, a constant
speed may not be safe in heavy traffic, or on winding or slippery roads. With the cruise control system
engaged, the engine speed will not return to idle when removing the foot from
the accelerator. Please
observe all local and national speed limits. Passing: When you want to drive
faster for a brief moment, for example when passing another vehicle, actuate
the accelerator. When you take
your foot off the accelerator pedal, the preset speed will automatically be
resumed. Gearshifting:
When
shifting gears, the automatic speed control is only disengaged as long as the
clutch pedal is depressed. The
preset speed will be resumed as soon as you take your foot off the clutch
pedal. Braking
and stopping: Whenever you apply the brake or come to a stop, the automatic speed
control is disengaged. Move the
lever down, and the preset speed will be resumed. Switching
system off:
To switch the automatic speed control off, move the lever toward you. To resume the preset speed, move the
lever down. To change the preset
cruising speed Increase preset speed: Accelerate
by depressing the accelerator pedal.
When the desire speed is reached push lever toward instrument cluster
and take your foot off the accelerator pedal. Now the new cruising speed is set and stored in the
memory. As
an alternative, you can hold the lever in the front position, without
depressing the accelerator pedal.
The car will accelerate on its own. When the desired speed is reached, release the lever. Decrease preset speed: Apply
the brake, which will disengage the automatic speed control. When the vehicle has slowed down to
the desired speed, push lever toward instrument cluster to set the new
cruising speed. As
an alternative, disengage the automatic speed control by moving the lever
toward you. When the vehicle has
slowed down to the desired speed, push lever toward instrument cluster to
register the new cruising speed in the memory. Note: When driving up a hill,
if the engine power is insufficient in a particular gear, the speed control
will be disengaged automatically.
Shift to a lower gear to avoid lugging the engine. Switch
lever for windshield wiper/washer and headlight washer This
lever has 6 switch positions. The
electric wiper system is actuated by pulling the lever up or down to the
following 4 positions: 0
wipers turned off 1
wipers on slow speed 2
wipers on medium speed 3
wipers on fast speed 4
wipers on intermittent speed The
intermittent wiper interval can be adjusted by turning thumbwheel on the
right side underneath the instrument cluster. The
electric washer system is actuated as follows: 5
Pull lever toward steering wheel to operate windshield washer. Fluid can be sprayed into the
windshield from any selected wiper speed position. When the ignition is switched on, the washer nozzles are
heated, depending on the outdoor temperature. Nevertheless, a commercial
windshield anti-freeze solution should be added to the windshield washer
water during cold weather conditions. 6
Push lever toward instrument cluster to operate headlight washer. The
headlight washer system operates only with the headlights on and raised. Avoid running the wiper blades over a dry windshield to prevent scratching the glass. Spray on washer fluid first. A scratched windshield will reduce visibility. Always
loosen blades frozen to glass before operating wipers to prevent damage to
wiper motor. WARNING Worn
or dirty wiper blades will reduce visibility, making driving hazardous. Clean blades regularly to remove road
film and carwash wax buildup. In
vehicles without Sekuriflex windshields, the plastic coating on the inside of
the windshield must not have gummed labels put on it or be cleaned using
aggressive agents or dry methods.
If very dirty, it can be cleaned with benzine. Make certain that the plastic coating
is not damaged in cleaning by hard objects such as jewelry or wristwatches. Intensive
windshield cleaning With
the intensive cleaning feature you can remove even firmly adhering silicon
dirt from the windshield.
Briefly depress switch on the right side underneath the instrument
cluster and the metering pump will pump the special Porsche cleaning solution
onto the windshield. The
length of spraying is limited by a time-delay relay in order to prevent
excessive use. If necessary,
repeat the operation. Then turn
on the windshield washer system. |
