Maintenance and care
etc., molded into the sidewall of 
each tire.
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  

4206-3. Do-it-yourself maintenance
HIGHLANDER HV_Udriving on snow-covered or icy 
roads. For driving on snow-covered 
roads or icy roads, the use of snow 
tires is recommended. When install-
ing snow tires, be sure to replace all 
four tires.
●All season tires
All season tires are designed to pro-
vide better traction in snow and to 
be adequate for driving in most win-
ter conditions a s well as for use 
year-round. All season tires, how-
ever, do not have  adequate traction 
performance compared with snow 
tires in heavy or loose snow. Also, 
all season tires fall short in accelera-
tion and handling performance com-
pared with summer tires in highway 
driving.
●Snow tires
For driving on snow-covered roads 
or icy roads, we recommend using 
snow tires. If you need snow tires, 
select tires of the same size, con-
struction and load  capacity as the 
originally installed tires. Since your 
vehicle has radial t ires as original 
equipment, make sure your snow 
tires also have radial construction. 
Do not install stud ded tires without 
first checking local regulations for 
possible restrictions. Snow tires 
should be installed on all wheels. 
(  P.327)
■If the tread on snow tires wears 
down below 0.16 in. (4 mm)
The effectiveness of the tires as 
snow tires is lost.
WA R N I N G
■When inspecting or replacing 
tires
Observe the following precautions 
to prevent accidents.
Failure to do so may cause dam-
age to parts of the drive train as 
well as dangerous handling char-
acteristics, which may lead to an 
accident resulting in death or seri-
ous injury.
●Do not mix tires of different 
makes, models or tread pat-
terns.
Also, do not mix tires of remark-
ably different treadwear.
●Do not use tire sizes other than 
those recommended by Toyota.
●Do not mix differently con-
structed tires (rad ial, bias-belted 
or bias-ply tires).
●Do not mix summer, all season 
and snow tires.
●Do not use tires  that have been 
used on another vehicle.
Do not use tires if you do not 
know how they were used previ-
ously.
●Do not tow if your vehicle has a 
compact spare tire installed.
NOTICE
■Driving on rough roads
Take particular care when driving 
on roads with loose surfaces or 
potholes.
These conditions may cause 
losses in tire inflation pressure, 
reducing the cush ioning ability of 
the tires. In addition, driving on 
rough roads may cause damage 
to the tires themselves, as well as 
the vehicle’s wheels and body.

■Electric power steering system 
warning light (warning buzzer)
When the 12-volt battery charge 
becomes insufficien t or the voltage 
temporarily drops, the electric power 
steering system warning light may 
come on and the warning buzzer 
may sound.
■When the tire pressure warning 
light comes on
Inspect the tires to check if a tire is 
punctured.
If a tire is punctured:  P.474
If none of the tires are punctured:
Turn the power switch off then turn it 
to ON. Check if the tire pressure 
warning light comes on or blinks.
If the tire pressure warning light 
blinks for 1 minute then stays on
There may be a malfunction in the 
tire pressure warning system. Have 
the vehicle inspected by your Toyota 
dealer immediately.
If the tire pressure warning light 
comes on
1 After the temperature of the tires 
has lowered sufficiently, check 
the inflation pressure of each tire 
and adjust them to the specified 
level.
2 If the warning light does not turn 
off even after several minutes 
have elapsed, check that the 
inflation pressure  of each tire is 
at the specified level and perform 
initialization. ( P.425)
If the warning light does not turn off 
several minutes afte r the initializa-
tion has been perf ormed, have the 
vehicle inspected by your Toyota 
dealer immediately.
■The tire pressure warning light 
may come on due to natural 
causes
The tire pressure  warning light may 
come on due to natural causes such 
as natural air leaks and tire inflation 
pressure changes caused by tem-
perature. In this case, adjusting the  tire inflation pressure will turn off the 
warning ligh
t (after a few minutes).
■When a tire is replaced with a 
spare tire
The compact spare tire is not 
equipped with a tire pressure warn-
ing valve and tran smitter. If a tire 
goes flat, the tire pressure warning 
light will not turn off even though the 
flat tire has been replaced with the 
spare tire. Replac e the spare tire 
with the repaired tire and adjust the 
tire inflation pressure. The tire pres-
sure warning light will go off after a 
few minutes.

on
Stop your vehicle in a safe place 
immediately and contact your Toy-
ota dealer.
The vehicle will become 
extremely unstable during brak-
ing, and the ABS system may fail, 
which could cause an accident 
resulting in death o r serious injury.
■When the electric power

When the light comes on yellow, 
the assist to the power steering is 
restricted. When the light comes 
on red, the assis t to the power 
steering is lost and handling oper-
ations of the steering wheel 
become extremely heavy.
When steering wheel operations 
are heavier than usual, grip the 
steering wheel firmly and operate 
it using more fo rce than usual.

■If the tire pressure warning 
light comes on
Be sure to observe the following 
precautions.
Failure to do so could cause a 
loss of vehicle control and result 
in death or serious injury.
●Stop your vehicle in a safe place 
as soon as possible. Adjust the 
tire inflation pressure immedi-
ately.
●If the tire pressure warning light 
comes on even after tire infla-
tion pressure adjustment, it is 
probable that y ou have a flat 
tire. Check the ti res. If a tire is 
flat, change it with the spare tire 
and have the flat tire repaired by 
the nearest Toy ota dealer.
●Avoid abrupt maneuvering and 
braking.
If the vehicle tires deteriorate, 
you could lose control of the 
steering wheel or the brakes.
■If a blowout or sudden air 
leakage should occur
The tire pressure warning system 
may not activate immediately.
■Maintenance of the tires
Each tire, including the spare (if 
provided), should be checked 
monthly when cold and inflated to 
the inflation pressure recom-
mended by the vehicle manufac-
turer on the vehicle placard or tire 
inflation pressure label (tire and 
load information label). (If your 
vehicle has tires of a different size 
than the size indicated on the 
vehicle placard or tire inflation 
pressure label [tire and load infor-
mation label], you should deter-
mine the proper tire inflation 
pressure for those tires.)
As an added safety feature, your 
vehicle has been equipped with a 
tire pressure monitoring system 
(TPMS-tire pressure warning sys-
tem) that illuminates a low tire 
pressure telltale (tire pressure 
warning light) w hen one or more 
of your tires is significantly 
under-inflated. Accordingly, when 
the low tire pressure telltale (tire 
pressure warning light) illumi-
nates, you should stop and check 
your tires as soon as possible, 
and inflate them to the proper 
pressure. Driving on a signifi-
cantly under-inflat ed tire causes 
the tire to overhea t and can lead 
to tire failure. Under-inflation also 
reduces fuel efficiency and tire 
tread life, and may  affect the vehi-
cle’s handling and stopping ability.
Please note that the TPMS (tire 
pressure warning system) is not a 
substitute for proper tire mainte-
nance, and it is the driver’s 
responsibility to m aintain correct 
tire pressure, even  if under-infla-
tion has not reached the level to 
trigger illuminati on of the TPMS 
low tire pressure te lltale (tire pres-
sure warning light).
Your vehicle has also been 
equipped with a TPMS (tire pres-
sure warning system) malfunc-
tion indicator to indicate when the 
system is not operating properly. 
The TPMS (tire pressure warning 
system) malfunction indicator is 
combined with the low tire pres-
sure telltale (tire pressure warning 
light). When the  system detects a 
malfunction, the te lltale will flash 
for approximately one minute and 
then remain continuously illumi-
nated. This sequence will con-
tinue upon subsequent vehicle 
start-ups as long as the malfunc-
tion exists. When the malfunction 
indicator is illu minated, the sys-
tem may not be ab le to detect or 
signal low tire pressure as 
intended.
