1987 PORSCHE 944 jump start

Controls for Automatic Transmission
The selector lever has 6 positions:

Park
Rev erse

Neutral
Driv e
Low
Low




... If the selector lever is unintentionally mo ved
into Neutral (N) while driving, take your foot off
the accelerator pedal and wait until the engine
speed has dropped to idle before selecting a driving position.
Never shift into Reverse (R) or Park (P) when
the car is in motion.
... Never get out of the driver's seat when the
engine is running and the selector lever is not in the "P" position. Move the selector lever to
"P" and apply parking brake.
... Always make sure the selector lever is in the
"P" position when checking under the hood.
Otherwise, any increase in engine speed may
set the vehicle in motion, even with the
parking brake applied.
... A driving position must never be used for
holding the vehicle at rest uphill. Always use
your foot brakes when stopped on inclines.
Driving the Automatic Transmission
The Automatic Transmission has 3 forward
gears and one reverse. In driving positions D
and 2 the Automatic Transmission changes
gears automatically while driving.
Position D
is the driving position normally used for city and highway driving. It ranges from zero to top
speed, and all three gears shift automatically
depending on driving speed.

Start in Park
The selector lever has a push button in the
handle. The push button must be
depressed when selecting the following
positions:
From P to R
R to P depress push button
N to R in handle
2 to 1
The selector lever can be moved freely
between the other positions.
The respective position is illuminated in the tachometer as long as the ignition key is in
the ignition lock.
Remember the following basic rules:

... Apply the parking brake or foot brake before
selecting a driving position. When the selector
lever is in a driving position, the car may creep
even at idle speed. Therefore, do not release
the parking brake or foot brake until you are
ready to move.
... Do not accelerate while selecting a driving
position. Wait for positive engagement. At this
time the engine must run at idle speed so that
no undue stress will be placed on the automatic
clutches in the transmission.

Position 2
is to be used for mountain driving or slow
driving, when towing a trailer and also when
you want to make use of the engine's braking
effect. In "2", only the first and second gears
will engage automatically. Therefore, only shift down into position "2" when the speed is below 63 mph or 100 km/h. It is not necessary to let up on the accelerator.
Position 1
is needed on rare occasions. It should only be
used up to 25 mph or 40 km/h. In "1" the
transmission will stay in first gear and not shift
into the second or third gear.
Only shift down into "1" when driving speed is below 25
mph or 40 km/h.
The reverse position R
Reverse should be selected only when the car has come to a full stop and the engine is
running at idle speed.
The back-up lights come on automatically
when you engage Reverse (with ignition on). Starting the engine
is only possible when the selector lever is in
Neutral or Park (N or P) . As long as one of
the driving positions is engaged a safety
switch prevents the engine from being started.

Emergency starting
Your Porsche with Automatic Transmission
cannot be started by pushing or towing.
Should the engine fail to start see "Emergency starting with jumper cables" or consult your
nearest authorized Porsche dealer.
DO NOT START OR TOW the car without
ATF in the transmission, as this will result
in serious damage to transmission and
torque converter.
Putting the car in gear
With the parking brake or foot brake set, shift
into the position you wish to use, usually
position D. To accelerate, release the brake
and depress the gas pedal.
WARNING
Do not release the brake before you are
prepared to move, because power is
transmitted to the wheels as soon as a
driving position is engaged.
Selecting a driving position while driving
is easy. Simply release the accelerator pedal
and move the selector lever from the position
you are in into the position you want. Then
step on the accelerator again.
WARNING
Do not shift to a lower driving position
until vehicle speed has dropped below the
specified limits. Engine speed will sudden-

ly increase and may cause engine damage and loss of vehicle control.
Stopping
When stopping temporarily, at traffic lights for
example, it is not necessary to move the
selector lever to Neutral. Simply apply the
brakes. To start again release the brake and
accelerate.
Parking
When parking your car, apply the parking
brake first, and then move the selector lever to position P. To do this, depress the button and
push the lever through R to P. The
transmission is then mechanically locked.
Park may only be engaged when the car is
stationary.
Do not remove the key from the ignition
steering lock until you have parked the car, because removal of the key locks the
steering wheel.
Shift out of the Park position, before releasing
the parking brake.
When the car is parked on a steep hill, shifting
out of Park may be a little harder. This is due
to the weight the car exerts on the
transmission.

must be charged at least every 6 weeks. A
discharged battery allows rapid formation of
sulfates, leading to premature deterioration of
the plates.
WARNING
Charge battery in a well ventilated area.
Keep away from open flame or electrical
spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
Electrolyte fluid that may spill during charging should be washed off with a solution of warm water and baking soda to neutralize the acid. If you get electrolyte in your eyes or on your
skin, immediately rinse with cold water for
several minutes and call a doctor.
Never charge a frozen battery. It may
explode because of gas trapped in the ice.
Allow a frozen battery to thaw out first. Never use a fast charger as a booster to start the engine. This may seriously damage the
vehicle's electrical system and the charger.
Fast charging a battery is dangerous and
should only be attempted by a competent
mechanic with the proper equipment.
Slow battery charging
WARNING
Heed all warnings and follow instructions
that come with your battery charger.


Disconnect battery cables and remove the
battery.
All vent caps should be open. If fluid level is low, it should be topped up to the full mark in
each cell.
Connect charger cables.
Charger cables must be connected
POSITIVE (+) to POSITIVE (+) and
NEGATIVE (-) to NEGATIVE (-).
Do not connect or disconnect charger cables while charger is operating. Switch on charger. Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
Rated capacity of the battery in your vehicle
is listed on the battery housing.
After charging, turn off charger and disconnect charger cables. Tighten the vent caps and reinstall battery.

Emergency Starting with Jumper Cables
WARNING
Improper use of booster battery to start a
vehicle may cause an explosion.
Lead-acid batteries generate explosive
gases. Keep sparks, flame and lighted
cigarettes away from batteries.
Do not charge a frozen battery, thaw it out
first. Gas trapped in the ice may cause an
explosion.
No attempt should be made to jump start any vehicle with a low electrolyte level in the
battery.
Check electrolyte level of each cell. If
necessary, fill with distilled water to just
above plates.
Make sure the voltage of both batteries is the same. The capacity (Ah) of the booster battery
should not be lower than that of the
discharged battery.
Vehicle with discharged battery: turn off
lights and accessories, remove key, move
lever to N or P and set parking brake.
Vehicle with booster battery should not be
running. Disconnect ground cable.
Remove vent caps from booster battery and
discharged battery. Preferably lay a cloth
over open vents to reduce explosion hazard.

How to use jumper cables WARNING
To avoid serious personal injury and damage to the vehicle, heed all warnings
and instructions of the jumper cable
manufacturer. The jumper cables must be long enough so that neither vehicles nor cables touch
another.
Improper hook-up of jumper cables can
ruin the alternator.
Always connect POSITIVE (+) to POSITIVE
(+), and NEGATIVE (-) to ground on engine
block.
1. Connect clamp of plus-cable to positive (+) terminal of discharged battery (1).
2.
Connect clamp on opposite end of cable to
positive (+) terminal of booster battery (2).
3.
Connect clamp of minus-cable to negative
(-) terminal of booster battery (3).
4.
Connect clamp on opposite end of cable to
a bare metal part bolted directly to the
engine block or to the engine block itself (x)
of car with discharged battery. Connect
clamp as far away from battery as possible.
5. Start engine in the usual manner. If engine
fails to start, do not continue to crank but
contact nearest workshop.
6.
With engine running, remove jumper cables from both cars in exact reverse order: Steps 4 through 1.


7. Reconnect ground cable of booster battery.
A - Discharged Battery
B - Booster Battery
Do not try to start car by pushing or towing.
Damage to the catalytic converter, the
transmission, and/or other components of the
car may result.
