When trouble arises
NOTICE
■If “Maintenance Required For
Traction Battery At Your
Dealer” is displayed
This message indi cates that the
traction battery may require
inspection or replacement. Have
the vehicle inspected by your Toy-
ota dealer immediately.
Do not continue driving the vehi-
cle, as the fuel cell system may
become not able to be started
again.
If you have a flat tire
Your vehicle is not equipped
with a spare tire, but instead
is equipped with an emer-
gency tire puncture repair
kit.
A puncture caused by a nail
or screw passing through
the tire tread can be
repaired temporarily using
the emergency tire puncture
repair kit. (The kit contains a
bottle of sealant. The seal-
ant can be used only once
to temporarily repair one
tire without removing the
nail or screw from the tire.)
Depending on the damage,
this kit cannot be used to
repair the tire. ( P.468)
After temporarily repairing
the tire with the kit, have the
tire repaired or replaced by
your Toyota dealer. Repairs
conducted using the emer-
gency tire puncture repair
kit are only a temporary
measure. Have the tire
repaired and replaced as
soon as possible.
WARNING
■If you have a flat tire
Do not continue driving with a flat
tire.
Driving even a short distance with
a flat tire can damage the tire and
the wheel beyond repair, which
could result in an accident.

When trouble arises
The air pressure gauge will
display the actual tire inflation
pressure about 1 to 5 min-
utes after the switch is turned
on.
 Turn the compressor switch
off and then check the tire
inflation pressure. Being care-
ful not to over inflate, check
and repeat the inflation proce-
dure until the specified tire
inflation pressure is reached.
 The tire can be inflated for
about 5 to 20 minutes
(depending on the outside
temperature). If the tire infla-
tion pressure is still lower than
the specified point after infla-
tion for 25 minutes, the tire is
too damaged to be repaired.
Turn the compressor switch
off and contact your Toyota
dealer.
 If the tire inflation pressure
exceeds the specified air
pressure, let out some air to
adjust the tire inflation pres-
sure. ( P.476, 501)
15 With the compressor switch
off, disconnect the hose from
the valve on the tire and then
pull out the power plug from
the power outlet socket.
Some sealant may leak when the
hose is removed.
16 Install the valve cap onto the
valve of the emergency
repaired tire. 17Attach the air release cap to
the end of the hose.
If the air release cap is not
attached, the sealant may leak and
the vehicle may get dirty.
18Temporarily store the bottle in the luggage compartment
while it is connected to the
compressor.
19To spread the liquid sealant evenly within the tire, imme-
diately drive safely for about
3 miles (5 km) below 50 mph
(80 km/h).
20After driving, stop your vehi- cle in a safe place on a hard,
flat surface and reconnect
the repair kit.
Remove the air release cap from
the hose before reconnecting the
hose.
