Practical Tips, Emergency Service
Screw in two assembly aids for vehicles with Porsche
Ceramic Composite Brake10.Take the wheel off and put a new wheel on.
Please see the chapter “WHEEL BOLTS” on
Page 248.
11.Insert wheel bolts and tighten by hand.
12.Remove assembly aids, screw in remaining
wheel bolts.
Initially tighten bolts only slightly in diagonally
opposite sequence so that the wheel
is centred.13.Inflate the tire if necessary.
Please see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
14.Lower the car fully and remove the jack.
15.Tighten wheel bolts in diagonally opposite
sequence.
fImmediately after changing a wheel, use
a torque wrench to check the prescribed
tightening torque (96 ftlb./130 Nm).
Note on operation for vehicles with
Tire Pressure Monitoring
fOn vehicles with Tire Pressure Monitoring, the
settings on the on-board computer must be
updated after the wheel change.
fPlease see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 143.
Checking tire pressure with a
pressure gage1. Remove the valve stem cap from the tire.
2. Press the pressure gage 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 gage.
3. Read the tire pressure on the gage 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 see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
4. Remove the pressure gage.
fPlease see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 143.

Flat Tire
Warning!
Failure to follow these instructions may result
in serious personal injury to you or to by-
standers.
fIf 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 motor-
ists. Set the parking brake.
fDo not park your vehicle where it may contact
dry grass, brush or other flammable materials.
The hot parts of the exhaust system could set
such materials on fire, thereby causing both
property damage and serious personal injury or death.
A tire sealant and compressor with pressure
tester are located in the luggage compartment.
fPlease observe the safety and operating in-
structions on the special sealant bottle with a
special Porsche part number and on the com-
pressor – these are essential.Important note
Sealing the tire with the tire repair kit is only
an emergency repair. Even with the tire air-
tight, it may be used only for short journeys
in an emergency.
The maximum permitted speed is 50 mph
(80 km/h).
fDo not use commercially available sealant or
tire inflating bottles.
Use only the tire sealant located in the luggage
compartment.
Warning!
Risk of accident, resulting in serious
personal injury or death.
fHave tires replaced by a specialist workshop
as soon as possible.
fAvoid hard acceleration and high cornering speeds.

A- Filler bottle
B- Filler hoseTire sealantThe tire sealant can be used to seal small cuts,
especially in the tire tread.
Sealing the tire with the tire sealant is only an
emergency repair, so you can drive to the next
workshop. Even with the tire air-tight, it may be
used only for short journeys in an emergency.The tire sealant and a compressor with pressure
tester can be found in the luggage compartment.
The tire sealant comprises:
– A filler bottle
– A sticker denoting the maximum permissible
speed for the driver’s field of vision
– A filler hose
– A valve turner and
– A spare valve insert.
Danger!
Risk of accident, resulting in serious per-
sonal injury or death.
fUse the tire sealant only in the case of cuts or
punctures no larger than 0.15 in. (4 mm).
fNever use the tire sealant if the rim is dam-aged.
Warning!
The sealant is highly flammable and harmful
to health.
fFire, naked flame and smoking are prohibited
when handling tire sealant.
fAvoid contact with skin, eyes or clothing due to
caustic chemical properties of the tire sealant.
fKeep tire sealant away from children.
fDo not inhale vapors, due to consequent harm
to personal health resulting in serious personal injury or death.
In case of contact with the sealant:
fIf sealant gets on the skin or in the eyes,
thoroughly rinse the affected part of the body
off immediately.
fChange soiled clothing immediately.
fGet medical attention immediately in the event
of an allergic reaction.
fIf sealant was swallowed, thoroughly rinse out
the mouth without delay and drink plenty of
water.
Do not induce vomiting.
Get medical attention immediately.

F- Tire valveInserting sealant
1. Leave the object that caused the puncture in
the tire.
2. Remove sealant and the enclosed sticker from
the luggage compartment.
3. Adhere the sticker in the driver's field of vision.
4. Shake filler bottle A.5. Screw filler hose B onto the filler bottle.
The filler bottle is now open.
6. Unscrew valve cap from tire valve F.
7. Remove valve insert E from the tire valve with
valve turner D.
Keep the valve insert in a clean and dry place.
8. Remove plug C of the filler hose B.
9. Push filler hose onto the tire valve.
10.Hold filler bottle higher than the level of the tire
valve and press it together forcefully until the
bottle is completely emptied into the tire.
11.Pull filler hose off the tire valve.
12.Twist the valve insert firmly into the tire valve
using the valve turner.
13.Connect the compressor to the cigarette light-
er and inflate the tire to the prescribed tire
pressure.
Please see the chapter “TIRE PRESSURES FOR
COLD TIRES (68 °F / 20 °C)” on Page 289.
14.Screw valve cap onto the tire valve.
15.Check the tire pressure after driving for around
10 minutes.
If the tire pressure is less than 22 psi (1.5 bar),
do not continue driving.
If a value of more than 22 psi (1.5 bar) is indi-
cated, correct the pressure to the prescribed
value.16.Please consult your authorized Porsche
dealer.
Note on operation for vehicles with
Tire Pressure Monitoring
fOn vehicles with Tire Pressure Monitoring, the
settings on the on-board computer must be
updated after the wheel change.
Please see the chapter “TPM TIRE PRESSURE
MONITORING” on Page 147.
Care Instructions
After drying, any sealant that emerges can be
peeled off like a film.
Warning!
Risk of accident, resulting in serious per-
sonal injury or death.
fHave the tire replaced by an authorized
Porsche dealer immediately.
fAvoid hard acceleration and high cornering
speeds.
fDo not exceed maximum speed of 50 mph
(80 km/h).
fPlease always observe the safety and opera-
ting instructions, which can be found in the
separate operating instructions for the sealant and on the compressor.

Adjusting HeadlightsfPlease see the chapter “LIGHTS, REPLACING
BULBS” on Page 269.
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.
