8047-2. Steps to take in an emergency
GS350/250_EE (OM30C36E)Check the degree of the tire damage.
A tire should only be repaired
with the emergency tire puncture
repair kit if the damage is caused
by a nail or screw passing
through the tire tread.
• Do not remove the nail or
screw from the tire. Removing
the object may widen the
opening and disenable emer-
gency repair with the kit.
• To avoid sealant leakage,
move the vehicle until the area
of the puncture, if known, is
positioned at the top of the
tire.

Screw the end of the hose clock-
wise as far as possible.
Check the specified tire infla-
tion pressure.
Tire inflation pressure is specified
on the label as shown. (P. 850)
Start the engine. (P. 207)
To inject the sealant and

8087-2. Steps to take in an emergency
GS350/250_EE (OM30C36E)Inflate the tire until the recom-
mended pressure is reached.
The sealant will be injected
and the pressure will spike
to 300 kPa (3.0 kgf/cm
2 or
bar, 44 psi) or 400 kPa
(4.0 kgf/cm
2 or bar, 58 psi),
then gradually decrease.
The air pressure gauge will
display the actual tire infla-
tion pressure about 1 minute
after the switch is turned on.
• Turn the compressor switch
off and then check the tire
inflation pressure. Being
careful not to over inflate,
check and repeat the inflation
procedure until the recom-
mended tire inflation pres-
sure is reached.
• If the needle of the air pres-
sure gauge reaches the red
zone (450 kPa [4.5 kgf/cm
2
or bar, 65 psi] or more), there
may be a malfunction in the
tire or in the kit itself. Stop
operation immediately.
• If the tire inflation pressure is
still lower than the recom-
mended level after inflation
for 10 minutes with the
switch on, the tire is too dam-
aged to be repaired. Turn the
compressor switch off and
contact any authorized Lexus
dealer or repairer, or another
duly qualified and equipped
professional.

• If the tire inflation pressure
exceeds the recommended
level, let out some air to
adjust the tire inflation pres-
sure.
(P. 813)
Disconnect the hose from the valve on the tire and then pull out
the power plug from the power outlet socket.
To spread the liquid sealant evenly within the tire, immediately
drive for about 5 km (3 miles).
After driving for about 5 km
(3 miles), stop your vehicle in
a safe place on a hard, flat sur-
face and reconnect the com-
pressor.12

8107-2. Steps to take in an emergency
GS350/250_EE (OM30C36E)Turn the compressor switch on
and wait for several seconds,
then turn it off. Check the tire
inflation pressure.
If the tire inflation pressure
is below 130 kPa (1.3 kgf/
cm
2 or bar, 19 psi): The
puncture cannot be repaired.
Contact any authorized
Lexus dealer or repairer, or
another duly qualified and
equipped professional.
If the tire inflation pressure
is between 130 kPa (1.3 kgf/
cm
2 or bar, 19 psi) and a
point below the recom-
mended level: The tire can
be repaired. Proceed to step
.
If the tire inflation pressure
is at the recommended
level: Proceed to step .
Turn the compressor switch on to inflate the tire until the recom-
mended tire inflation pressure is reached. Drive for about 5 km (3
miles) and then perform step .
