Wheel Bolts
Warning!
Risk of wheel bolt breakage and wheel sepa-
ration, resulting in severe personal injury or
death.
fFollow all instructions concerning wheel bolts. fAlways clean the wheel bolts before fitting.
fApply a thin coat of Optimoly TA (aluminium
paste) on the thread and between the bolt head
and movable spherical cap ring (arrows).
The bearing surface of the spherical cap
facing the wheel must not be greased.
fReplace damaged wheel bolts.
Only use the Original Porsche wheel bolts
specially designed for this vehicle type.
Tightening torque Tightening torque of wheel bolts:
130 Nm/96 ftlb. Wheel Securing Bolts The wrench socket for the wheel securing bolts is
in the tool box.
To loosen or tighten the wheel bolt with anti-theft
protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
fWhen positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
Checking tire pressure with a
pressure gaugefPlease observe the chapter “TPC TIRE PRES-
SURE MONITORING” on Page 103.
1. Remove the valve stem cap from the tire.
2. Press the pressure gauge onto the valve stem.
Note on operation
fDo not press too hard or force the valve stem
sideways, or air will escape.
If the sound of air escaping from the tire is
heard, reposition the pressure gauge.
3. Read the tire pressure on the gauge stem and
compare it to the permissble tire pressure.
This information can be found on the tire pres-
sure plate or in the chapter Technical Data.
Please observe the chapter “TIRE PRESSURE
FOR COLD TIRES” on Page 284.
4. Remove the pressure gauge.

Adjusting Headlights fPlease observe the chapter “REPLACING BUL-
BS” on Page 258.
Adjustment
The adjustment is made with the vehicle ready to
drive and the fuel tank completely filled.
The driver’s seat must be loaded by a person or a
165 lbs. (75 kg) weight and the tire pressures
must meet the prescribed values.
After being loaded, the car must be rolled a few
meters so that the suspension can settle.
For checking the headlight adjustment, the verti-
cal position of the cutoff of the lowbeam (see fig.)
has to be projected on a vertical screen (wall) in
distance of 24.6 ft. (7.5 m) from the front lens of
the headlamp.
The correct position of the cutoff is 2.0 in. (5 cm)
at 24.6 ft. or 7.5 m (0.4°) below a horizontal line,
x cm from ground to the center of the headlamp
lens. Lateral adjustment of the headlights should be
carried out at a specialist workshop with an optical
adjustment unit.
Distance
Visual aim shall be performed at not less than
24.6 ft. (7.5) m (this value is a rounded down con-
version from the 25-foot distance typical of field
aim using a screen). The 24.6 ft. (7.5 m) distance
is measured from the headlamp lens to the view-
ing screen.
