2010 PORSCHE CAYENNE tire pressure

Minor Repairs
297
On vehicles without level control, the tire sealant
and a compressor with pressure tester can be
found under the cargo floor in the luggage com-
partment.
The tire sealant comprises:
– A filler bottle
– A filler hose
– A valve turner
– A spare valve insert
– A set of instructions and
– A sticker with the maximum permissible
speed.
Danger!
Risk of accident, resulting in serious
personal 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 damaged.
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 and clothing due
to caustic chemical properties of the tire seal-
ant.
fKeep tire sealant away from children.
fDo not inhale vapours, 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 without delay.
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.

Please see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
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.The settings for Tire Pressure Monitoring must be
update on the multi-purpose display after filling the
tire with sealant.
Please see the chapter “SETTING TIRE SEALANT/
SEALING SET” on Page 140.
Car care instruction
After drying, any sealant that emerges can be
peeled off like a film.
Warning!
Risk of accident, resulting in serious
personal injury or death.
fHave the tire replaced by a specialist work-
shop as soon as possible.
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.
Lifting the Vehicle with a Lifting
Platform or Garage liftfThe car must be raised only at the illustrated
jacking points.
Please see the chapter “LIFTING THE VEHICLE
WITH A LIFTING PLATFORM OR GARAGE LIFT”
on Page 298.
Please see the chapter “RAISING VEHICLE
WITH THE JACK” on Page 192.
fLifting at any other place may damage the

Changing a wheel with removal of 17 mm
spacer
Danger!
Risk of accident if the spacers are not
removed before mounting 18 inch tires or
collapsible spare wheel.
f17 mm spacers are always to be removed
before mounting 18 inch tires or a collapsible
spare wheel, because the wheel cannot be fitted correctly. Caution!
Risk of damage to wheel housings if the
spacers on the rear axle are not removed be-
fore fitting the snow chains.
f17 mm spacers must always be removed from the rear axle when snow chains are to be fitted.
fRemove spacers if 18 inch tires, snow chains
or a collapsible spare wheel are mounted.

Minor Repairs
Warning!
Risk of accident.
fThe collapsible spare wheel must be used only
over short distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1/16 in. (1.6 mm) high).
fNever deactivate the Porsche Stability
Management (PSM) system.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) and must not be exceeded
because of altered driving characteristics and
for reasons of wear.
The tread depth of the spare wheel is subject
to the same laws as the original tires.
fDo not use a collapsible spare wheel from a
different vehicle type.
fDo not mount the collapsible spare wheel from
your car on a different vehicle.
fOnly fit one collapsible spare wheel on the
vehicle at a time.
fOn vehicles with air suspension, use the tire fil-
ling connection A only to inflate the collapsible
spare wheel.
fTo avoid damage, do not use automatic car washes when the spare wheel is installed.After using the collapsible spare wheel
fRelease air by unscrewing the valve insert.
Notes on operation
The tire will revert to its original shape only after
several hours. Only then can it be stowed in the
spare wheel recess in the luggage compartment.
There is a plastic sheet in the tool box to store the
damaged wheel.
Maintenance Note
The collapsible spare wheel must be repaired only
by the manufacturer.
fPlease consult your authorized Porsche dealer
if the collapsible spare wheel is defective.
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 permissible tire pressure.
This information can be found on the tire pres-
sure plate in the left door aperture.
Please see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
4. Remove the pressure gage.

Spare wheel
Warning!
Risk of accident. The wheel and tire size and
the tire quality of the spare wheel and normal
wheel may differ.
If a spare wheel that differs from the normal
tires is used, this may impair the driving
behavior.
fThe spare wheel must be used only over short
distances in cases of emergency.
For safety reasons, replace the tires before
the wear indicators appear (webs in the tire
grooves, 1/16 in. (1.6 mm) high).
fNever deactivate the Porsche Stability
Management (PSM) system.
fIf the tire on the spare wheel is older than
4 years, the spare wheel should be used only
in the event of a flat.
fAvoid hard acceleration and high cornering
speeds.
The maximum permitted speed is 50 mph
(80 km/h) if the mounted spare wheel differs
from the other three wheels on the car. This
maximum speed must not be exceeded
because of altered driving characteristics and
for reasons of wear.
fDo not use a spare wheel from a different
vehicle type.
fDo not mount the spare wheel from your car on a different vehicle.Removing spare wheel from bracket
Warning!
Danger of injury if the spare wheel is
removed improperly.
fRemove the spare wheel only when the spare
wheel bracket is locked.
fRemove the spare wheel from the spare wheel
bracket with care. The wheel is very heavy [approx. 77 lbs. (35 kg)].
1. Unscrew all five wheel bolts.
2. Remove the top wheel bolt.
Remove assembly aid from the tool kit and
screw in instead of the wheel bolt.
Remove the remaining wheel bolts.
Fitting spare wheel on bracket
fInsert wheel bolts and tighten by hand.
Remove assembly aid and screw in remaining
wheel bolt.
Initially tighten bolts in diagonally opposite
sequence so that the wheel is centerd.
fPlease see the chapter “TIRE PRESSURES,
COLD (68 °F/20 °C)” on Page 354.
fAfter mounting the wheel, tighten all five wheel
bolts to 111 ftlb. (150 Nm).
