Replace the tires if the treadwear
indicators are showing on a tire.
■When to replace your vehicle’s
tires
Tires should be replaced if:
●The treadwear indicators are
showing on a tire.
●You have tire damage such as
cuts, splits, cracks deep enough
to expose the fabric, and bulges
indicating internal damage.
●A tire goes flat r epeatedly or can-
not be properly repaired due to the
size or location of a cut or other
damage.
If you are not sure, consult with your
Toyota dealer.
■Tire life
Any tire over 6 years old must be
checked by a qualified technician
even if it has seldom or never been
used or damage i s not obvious.
■Proper storage of the spare tire
As an improperly stored spare tire
may cause damage to the wire
cable that holds it, check that the
spare tire is stored properly on a
daily basis.
●If the stored spare tire appears to
be slanted or rattl es while driving,
the spare tire may not be properly
stored. Store the spare tire again
by performing the following tire
change procedure correctly: 1
If the spare tire is slanted, the
hoist assembly may be stuck in
the wheel opening. If the spare
tire rattles while driving, it may
not be fully raised. Lower the
spare tire to the ground and
make sure that the hoist assem-
bly is perpendicular to the wheel
opening.
2 Raise the tire slowly and steadily
until a click is heard and the jack
handle skips.
If the spare tire cannot be lowered,
the wire cable may be severed.
Have the vehicle inspected at your
Toyota dealer.
■Maximum load of tire
Check that the n umber given by
dividing the maximum load by 1.10
of the replacement tire is greater
than 1/2 of the Gross Axle Weight
Ratings (GAWR) of either the front
axle or the rear axle, whichever is
greater.
For the GAWR, see the Certification
Label.
For the maximum load of the tire,
see the load limit at maximum cold
tire inflation pressure mentioned on
the sidewall of the tire. ( P.516)
■Tire types
●Summer tires
Summer tires are high-speed perfor-
mance tires best suited to highway
driving under dry conditions. Since
summer tires do not have the same
traction performance as snow tires,
summer tires are inadequate for

HIGHLANDER HV_U
One of the following may be the
cause of the problem:
The electronic key may not be
functioning properly.
( P.489)
There may not be sufficient
fuel in the vehicle’s tank.
Refuel the vehicle.
There may be a malfunction
in the immobilizer system.
( P.79)
There may be a malfunction
in the steering lock system.
The hybrid system may be
malfunctioning due to an elec-
trical problem such as elec-
tronic key battery depletion or
a blown fuse. However,
depending on the type of mal-
function, an interim measure
is available to start the hybrid
system. ( P.487)
NOTICE
●Securely tighten the spare tire
clamp bolt to hold the spare
wheel carrier by the hook.
●Stow the flat tire in the spare tire
location. Failure to do so may
cause damage to the spare tire
carrier. Proper storage reduces
the possibility of i njury in a colli-
sion or during sudden braking.
●Have the flat tire repaired and
the spare tire replaced with it as
soon as possible.
■Proper storage of the spare
tire
●If the hoist assembly is slanted
when stowing a tire, the hoist
assembly may become stuck in
the wheel opening and the tire
may not be raised properly,
causing damage to the wheel or
the wire cable.
●Do not attempt to turn the spare
tire clamp bolt without a tire on
the hoist assembly, as doing so
may cause the wire cable to slip
off of the shaft inside the unit
and the wire cable may not be
able to be raised or lowered. If
the spare tire c lamp bolt has
been turned without a tire on the
hoist assembly and the wire
cable cannot be raised or low-
ered, contact your Toyota
dealer.

will not star t
Reasons for the hybrid sys-
tem not starting vary
depending on the situation.
Check the following and
perform the appropriate

The hybrid system will not
start even though the cor-
rect starting procedure is
being followed. ( P.213)
