6-3. Do-it-yourself maintenance

WARNING

When inspecting or replacing tires

Observe the following precautions to prevent accidents.

Failure to do so may cause damage to parts of the drive train as well as

dangerous  handling  characteristics,  which  may  lead  to  an  accident

resulting in death or serious injury.

Do not mix tires of different makes, models or tread patterns.

Also, do not mix tires of remarkably different treadwear.

Do not use tire sizes other than those recommended by Toyota.

Do not mix differently constructed tires (radial, 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 previously. 

When initializing the tire pressure warning system

Do not initialize the tire pressure warning system without first adjusting

the tire inflation pressure to the specified level. Otherwise, the tire pres-

sure warning light may not come on even if the tire inflation pressure is

low, or it may come on when the tire inflation pressure is actually nor-

mal.

NOTICE

Repairing or replacing tires, wheels, tire pressure warning valves,

transmitters and tire valve caps

When removing or fitting the wheels, tires or the tire pressure warning

valves  and  transmitters,  contact  your Toyota  dealer  as  the  tire  pres-

sure warning valves and transmitters may be damaged if not handled

correctly.

Make sure to install the tire valve caps. If the tire valve caps are not

installed,  water  could  enter  the  tire  pressure  warning  valves  and  the

tire pressure warning valves could be bound.

When replacing tire valve caps, do not use tire valve caps other than

those specified. The cap may become stuck.

To avoid damage to the tire pressure warning valves and transmit-

ters

When  a  tire  is  repaired  with  liquid  sealants,  the  tire  pressure  warning

valve  and  transmitter  may  not  operate  properly.  If  a  liquid  sealant  is

used, contact your Toyota dealer or other qualified service shop as soon

as  possible. After  use  of  liquid  sealant,  make  sure  to  replace  the  tire

pressure warning valve and transmitter when repairing or replacing the

tire. (

P. 522)

Driving on rough roads

Take particular care when driving on roads with loose surfaces or pot-

holes.

These conditions may cause losses in tire inflation pressure, reducing

the  cushioning  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.

Low profile tires (vehicles with 215/45R17 tires)

Low  profile  tires  may  cause  greater  damage  than  usual  to  the  wheel

when receiving impact from the road surface. Therefore pay attention to

the following:

Be sure to use proper tire inflation pressure. If tires are under-inflated,

they may be damaged more severely.

Avoid  pot  holes,  uneven  pavement,  curbs  and  other  road  hazards.

Failure to do so can lead to severe tire and wheel damage.

If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.

Tire valve
Tire pressure gauge

Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the gauge gradations.
If the tire inflation pressure is not at the recommended level, adjust
the pressure.
If you add too much air, press the center of the valve to deflate.
After  completing  the  tire  inflation  pressure  measurement  and
adjustment, apply soapy water to the valve and check for leakage.
Put the tire valve cap back on.

Tire inflation pressure check interval

You should check tire inflation pressure every two weeks, or at least once

a month.

Do not forget to check the spare.

Effects of incorrect tire inflation pressure

Driving with incorrect tire inflation pressure may result in the following:

Reduced fuel economy

Reduced driving comfort and poor handling

Reduced tire life due to wear

Reduced safety

Damage to the drive train

If a tire needs frequent inflating, have it checked by your Toyota dealer.

Instructions for checking tire inflation pressure

When checking tire inflation pressure, observe the following:

Check only when the tires are cold.

If  your  vehicle  has  been  parked  for  at  least  3  hours  or  has  not  been

driven for more than 1 mile or 1.5 km, you will get an accurate cold tire

inflation pressure reading.

Always use a tire pressure gauge.

It is difficult to judge if a tire is properly inflated based only on its appear-

ance.

It  is  normal  for  the  tire  inflation  pressure  to  be  higher  after  driving  as

heat is generated in the tire. Do not reduce tire inflation pressure after

driving.

Never exceed the vehicle capacity weight.

Passengers and luggage weight should be placed so that the vehicle is

balanced.

WARNING

Proper inflation is critical to save tire performance

Keep your tires properly inflated.

If the tires are not properly inflated, the following conditions may occur

which could lead to an accident resulting in death or serious injury:

Excessive wear

Uneven wear

Poor handling

Possibility of blowouts resulting from overheated tires

Air leaking from between tire and wheel

Wheel deformation and/or tire damage

Greater possibility of tire damage while driving (due to road hazards,

expansion joints, sharp edges in the road, etc.)

NOTICE

When inspecting and adjusting tire inflation pressure

Be sure to put the tire valve caps back on.

If a valve cap is not installed, dirt or moisture may get into the valve and

cause an air leak, resulting in decreased tire inflation pressure.

Wheels

When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width and
inset

*

.

Replacement wheels are available at your Toyota dealer.

*

: Conventionally referred to as “offset”.

Toyota does not recommend using the following:

Wheels of different sizes or types

Used wheels

Bent wheels that have been straightened

Use  only Toyota  wheel  nuts  and  wrenches  designed  for  use  with
your aluminum wheels.

When  rotating,  repairing  or  changing  your  tires,  check  that  the
wheel nuts are still tight after driving 1000 miles (1600 km).

Be  careful  not  to  damage  the  aluminum  wheels  when  using  tire
chains.

Use only Toyota genuine balance weights or equivalent and a plas-
tic or rubber hammer when balancing your wheels.

If  a  wheel  is  bent,  cracked  or  heavily  corroded,  it  should  be
replaced.  Otherwise,  the  tire  may  separate  from  the  wheel  or
cause a loss of handling control.

6-3. Do-it-yourself maintenance

When replacing wheels

The  wheels  of  your  vehicle  are  equipped  with  tire  pressure  warning

valves  and  transmitters  that  allow  the  tire  pressure  warning  system  to

provide advance warning in the event of a loss in tire inflation pressure.

Whenever wheels are replaced, tire pressure warning valves and trans-

mitters must be installed. (

P. 522)

WARNING

When replacing wheels

Do not use wheels that are a different size from those recommended in

the Owner’s Manual, as this may result in a loss of handling control.

Never  use  an  inner  tube  in  a  leaking  wheel  which  is  designed  for  a

tubeless tire. Doing so may result in an accident, causing death or seri-

ous injury.

When installing the wheel nuts

Never use oil or grease on the wheel bolts or wheel nuts.

Oil and grease may cause the wheel nuts to be excessively tightened,

leading to bolt or disc wheel damage. In addition, the oil or grease can

cause the wheel nuts to loosen and the wheel may fall off, causing an

accident  and  resulting  in  death  or  serious  injury.  Remove  any  oil  or

grease from the wheel bolts or wheel nuts.

Use of defective wheels prohibited

Do not use cracked or deformed wheels.

Doing so could cause the tire to leak air during driving, possibly causing

an accident.

Be sure to install the wheel nuts with

the  tapered  ends  facing  inward.

Installing  the  nuts  with  the  tapered

ends  facing  outward  can  cause  the

wheel  to  break  and eventually  cause

the  wheel  to  come  off  while  driving,

which  could  lead  to  an  accident

resulting in death or serious injury.

Scheduled maintenance of the air intake vent is necessary when

In some situations such as when the vehicle is used frequently or in heavy
traffic or dusty areas, the air intake vent may need to be cleaned more regu-
larly.  For  details,  refer  to  the  “Scheduled  Maintenance  Guide”  or  “Owner’s
Manual Supplement”.

Cleaning the air intake vent

Dust in the air intake vent may interfere with the cooling of the hybrid battery
(traction battery). If charging/discharging of the hybrid battery (traction bat-
tery) becomes limited, the distance that the vehicle can be driven using the
electric motor (traction motor) may be reduced and the fuel economy may
be reduced. Inspect and clean the air intake vent periodically.

Improper handling of the air intake vent cover and filter may result in dam-
age to them. If you have any concerns about cleaning the filter, contact your
Toyota dealer.

If “Maintenance required for Traction battery cooling parts See owner’s
manual” is shown on the multi-information display

If this warning message is shown on the multi-information display, remove
the air intake vent cover and clean the filter. (

P. 539)

After cleaning the air intake vent, start the hybrid system and check that the
warning message is no longer shown.
It may take approximately 20 minutes after the hybrid system is started until
the warning message disappears. If the warning message does not disap-
pear, have the vehicle inspected by your Toyota dealer.

WARNING

When cleaning the air intake vent

Do not use water or other liquids to clean the air intake vent. If water is
applied to the hybrid battery (traction battery) or other components, a mal-
function or fire may occur.

After a fuse is replaced

If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (

P. 556)

If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.

If there is an overload in a circuit

The fuses are designed to blow, protecting the wiring harness from damage.

When replacing light bulbs

Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload,  nongenuine  parts  or  parts  not  designed  for  this  vehicle  may  be
unusable.

WARNING

To prevent system breakdowns and vehicle fire

Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or
injury.

Never use a fuse of a higher amperage rating than that indicated, or use
any other object in place of a fuse.

Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.

Do not modify the fuses or fuse boxes.

NOTICE

Before replacing fuses

Have  the  cause  of  electrical  overload  determined  and  repaired  by  your
Toyota dealer as soon as possible.

WARNING

Replacing light bulbs

Be sure to stop the hybrid system and turn off the lights. Do not attempt to
replace the bulb immediately after turning off the lights. 
The bulbs become very hot and may cause burns.

Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.

Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.

Do  not  attempt  to  repair  or  disassemble  light  bulbs,  connectors,  electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.

To prevent damage or fire 

Make sure bulbs are fully seated and locked. 

Check the wattage of the bulb before installing to prevent heat damage.

WARNING

Observe the following precautions. 
Failure to do so may result in death or serious injury.

While towing

When towing using cables or chains, avoid sudden starts, etc. which place
excessive stress on the towing eyelets, cables or chains. The towing eye-
lets, cables or chains may become damaged, broken debris may hit peo-
ple, and cause serious damage.

Do not turn the power switch off. 
This  may  lead  to  an  accident  as  the  front  wheels  will  be  locked  by  the
parking lock.

Installing towing eyelets to the vehicle

The towing eyelets are only for the vehicle equipped with them. Do not use
the towing eyelets for another vehicle, and do not use the towing eyelets
for this vehicle on another vehicle.

Make sure that towing eyelets are installed securely.
If not securely installed, towing eyelets may come loose during towing.

NOTICE

To prevent damage to the vehicle when towing using a wheel-lift type
truck

When raising the vehicle, ensure adequate ground clearance for towing at
the  opposite  end  of  the  raised  vehicle.  Without  adequate  clearance,  the
vehicle could be damaged while being towed.

To prevent damage to the vehicle when towing with a sling-type truck

Do not tow with a sling-type truck, either from the front or rear.

To prevent damage to the vehicle during emergency towing

Do not secure cables or chains to the suspension components.

WARNING

When the electric power steering system warning light comes on

When  the  light  comes  on  yellow,  the  assist  to  the  power  steering  is
restricted. When the light comes on red, the assist to the power steering is
lost  and  handling  operations  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 force 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 immediately. 

Vehicles  with  emergency  tire  puncture  repair  kit:  If  the  tire  pressure

warning light comes on even after tire inflation pressure adjustment, it

is  probable  that  you  have  a  flat  tire.  Check  the  tires.  If  a  tire  is  flat,

repair the flat tire by using emergency tire puncture repair kit.

Vehicles  with  spare  tire:  If  the  tire  pressure  warning  light  comes  on

even  after  tire  inflation  pressure  adjustment,  it  is  probable  that  you

have a flat tire. Check the tires. If a tire is flat, change it with the spare

tire and have the flat tire repaired by the nearest Toyota 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.

WARNING

Maintenance of the tires

Each tire, including the spare (if provided), should be checked monthly

when  cold  and  inflated  to  the  inflation  pressure  recommended  by  the

vehicle  manufacturer  on  the  vehicle  placard  or  tire  inflation  pressure

label (tire and load information label). (If your vehicle has tires of a dif-

ferent size than the size indicated on the vehicle placard or tire inflation

pressure  label  [tire  and  load  information  label],  you  should  determine

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 system) that

illuminates a low tire pressure telltale (tire pressure warning light) when

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  significantly  under-

inflated  tire  causes  the  tire  to  overheat  and  can  lead  to  tire  failure.

Under-inflation also reduces fuel efficiency and tire tread life, and may

affect the vehicle’s handling and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a sub-

stitute for proper tire maintenance, and it is the driver’s responsibility to

maintain  correct  tire  pressure,  even  if  under-inflation  has  not  reached

the level to trigger illumination of the TPMS low tire pressure telltale (tire

pressure warning light).
Your vehicle has also been equipped with a TPMS (tire pressure warn-

ing  system)  malfunction  indicator  to  indicate  when  the  system  is  not

operating properly. The TPMS (tire pressure warning system) malfunc-

tion indicator is combined with the low tire pressure telltale (tire pressure

warning light). When the system detects a malfunction, the telltale will

flash for approximately one minute and then remain continuously illumi-

nated. This sequence will continue upon  subsequent vehicle  start-ups

as long as the malfunction exists. When the malfunction indicator is illu-

minated, the system may not be able to detect or signal low tire pres-

sure as intended.
TPMS (tire pressure warning system) malfunctions may occur for a vari-

ety of reasons, including the installation of replacement or alternate tires

or wheels on the vehicle that prevent the TPMS (tire pressure warning

system)  from  functioning  properly. Always  check  the TPMS  (tire  pres-

sure  warning  system)  malfunction  telltale  after  replacing  one  or  more

tires or wheels on your vehicle to ensure that the replacement or alter-

nate tires and wheels allow the TPMS (tire pressure warning system) to

continue to function properly.
