Changing a Tire
WARNING - Failure to follow these
instructions may result in serious personal injuries to you or to bystanders.
If you have a flat tire, move a safe distance off the road. Turn the emergency flasher on and use other warning devices
to alert other motorists.
Passengers must not remain in the vehicle when it is jacked up. Before you change a tire, be sure the ground is level and firm. If necessary, use a board under the jack to ensure that the jack does not sink into the ground. Set the parking brake and block the wheels opposite the flat tire on the other
side of the vehicle.
The jack is only to be used for changing
a tire. Do not use it as a support to work
under the car.
Never jack the car up by the body or the bumpers.
Sequence of operations:
1.
Loosen all wheel nuts. Do not yet remove
nuts.
2.
Securely place the jack in the jack support
at the indicated point. Place the jack at an
angle so that the jack base rests firmly on
the ground. If the ground is not firm under
the jack, use a board.
Do not raise the vehicle until you are sure
the jack is securely engaged.
3.
Raise the car by turning the handle
clockwise. Only raise the car as much as is
needed to change a wheel.
4.
Fully unscrew wheel nuts and remove wheel.
5. After you have mounted the spare wheel, insert the wheel nuts and hand tighten them crosswise. Snug wheel nuts with socket wrench and breaker bar.
6. To lower the car, turn the handle
counterclockwise till tire touches ground.
7.
Then go crosswise from one nut to another
tightening them firmly with the socket
wrench and breaker bar.
8. Fully lower the vehicle and remove jack.
9. Correct the air pressure of the tire you have just put on. Have flat tire repaired at next service stop.
Correct tightness of the wheel nuts is
important. The torque of 94 ft Ib (130 Nm) can
be obtained with a socket wrenc
h and breaker bar by any person of average strength. If in
doubt about the correct tightness of the wheel
nuts, have it checked with a torque wrench by
your dealer or a service station.

Lifting Vehicle
The jack ports are located below the middle of the door underneath the left and right rocker
panels, hidden from view.
Lifting with car jack
The car jack must never be used as a
support to work underneath the vehicle. If
the jack is accidentally dislodged, you
could be seriously injured. When working
under the vehicle always use safety stands specifically designed for this purpose.
WARNING
Jacking at any other place may damage the vehicle or may result in personal injuries.
The vehicle should never be lifted or jacked up from underneath the engine oil pan, the transmission housing, or the front or rear axle. This could lead to serious
damage.
Lifting with workshop hoist
Make sure there is sufficient clearance
between pads and vehicle before driving
vehicle onto hoist, especially if the vehicle
has a large front panel or spoiler. The vehicle must be lifted only at the lift points illustrated.
The front lift points are located on the inboard
side members of the underbody.
The rear lift points are located on the side
reinforcement brackets of the underbody.
Take care to avoid damaging critical
components which are close to the lift
points.
WARNING
When removing components such as
engine block, transmission housing, fuel
tank, wheels, front or rear axle, anchor
vehicle to hoist or add corresponding
weights to maintain the center of gravity.
Otherwise the vehicle might tilt or slip off
the hoist, causing serious damage or
personal injury.
Lifting with floor jack
The same lift points as illustrated for the hoist
also apply when using a floor jack. To avoid
damage to the underbody or chassis frame, it
is necessary to insert a rubber pad between
the floor jack and the lift points.

Sealed Beam Headlights
Replacing light units
1.
Turn on the ignition and depress light switch to the second stop to raise the concealed
headlights. Then turn off the ignition.
2.
Remove Phillips screw from headlight trim
(arrow), take off the plastic cover.
3.
Remove only the three recessed screws
(arrows) which secure the lamp unit
retaining ring, remove retaining ring, and
take out sealed beam unit.
4.
Disconnect plug from rear of unit.
5. Attach plug to rear of new unit.
6. Insert sealed beam unit and retaining ring,
tighten hold-down screws.
7.
Check headlight adjustment.
8. Install headlight trim and tighten retaining
screw.
Adjusting Headlights
Headlight adjustment should be done with a
headlight aiming device under the following
conditions:
At curb weight of car (i. e. car ready for use
and with full fuel tank).
Driver's seat should be occupied by a person
or a weight of approx. 165 Ibs (75 kg).
Tire pressure must be correct.
Roll car forward a few feet so that the
suspension seeks its normal position.

Fog Lights
On the 944 Turbo, before adjusting or
removing the fog lamp unit, loosen the
transparent side parts which are secured with
Phillips-head screws.
1. Loosen the Phillips screws (arrows) and
pull out the entire light unit.
2.
Pull out cable connector plug and unsnap
holding clamps.
3.
Replace defective bulb. Be sure the new
bulb is installed correctly.
4. Refasten holding clamps and plug in cable
connection.
5.
Reinstall light unit and fasten Phillips
screws securely.

Engine Oils
Use only engine oils which meet the
specifications designated by PORSCHE. Your Porsche dealer will be glad to advise you on
the correct type of oil for your engine.
All current engine oils are compatible with each other, i. e. when making an oil change it
is not necessary to flush the engine if you
wish to use a different brand or grade of oil. Since, however, each brand of oil has a
special composition, you should, if possible,
use the same oil brand if it becomes
necessary to top up between oil changes.
PORSCHE engines have long intervals
between oil changes. You can make best use
of these long oil change intervals by using
multigrade oils since these are largely
independent of seasonal fluctuations in
temperature.
If your vehicle is used frequently in stop-and-
go traffic in winter, the engine will not always
be properly warmed up. Condensation from
products of combustion may accumulate in
the oil. In this case, it is advisable to change
the oil in spring so that your engine once
again has a 100% efficient engine oil.
Engine oil performance class
Engine oil is not only a lubricant, but also
serves to keep the engine clean, to neutralize
the dirt which penetrates into the engine
through combustion and to protect the engine
against corrosion. To perform these functions, the oil is provided with additives which have
been specially developed for these functions.
So-called mineral oils are produced directly
from crude oil. The oils can be further refined
(hydrocrack oils) or totally converted through a number of chemical processes (synthetic oils). These oils are structurally more efficient and
require fewer additives than simple mineral
oils.
The efficiency of an oil is expressed, for
example, by the API classifications which are
divided into categories "S" and "C". The
degrees of quality are expressed by final
letters in alphabetical order: The requirements for PORSCHE engines are API class SE/CC
to SF/CD.
Viscosity
Like all liquids, engine oil is viscous when
cold, and thin-bodied when warm.
The viscosity of an oil is expressed by its SAE class. For cold viscosity (measured at
temperatures below 0°C) the SAE class is
given as a number and the letter "W" (as in
winter); for hot viscosity (measured at 100°C) the SAE class is given only as a number. The viscosity of an oil is, therefore, always the same if it has the same number of an SAE
class.
E. g.: A 10 W -30 oil and a 10 W-40 oil have
the same viscosity when cold (below 0°C);
when hot (at 100°C) the oil with the number 30 is thinner than the oil with the number 40.
Single-grade/multigrade oils
Oils with two viscosities are called multi-g
rade oils; oils with only one viscosity are termed
single-grade oils.
Single-grade oils can only be used for the
narrow temperature range identified by their
SAE number; multigrade oils cover a wider
temperature range (see chart).
Fuel efficient oils
Fuel efficient oils reduce internal friction in the
engine. PORSCHE approves only fuel
efficient oils which are structurally so stable
that they can be used in PORSCHE engines
both as summer and winter oils (see chart of
areas of application for oils of different
viscosity). These conditions are currently
fulfilled by synthetic or hydrocrack fuel
efficient oils.
