6-1. Maintenance and care

■

Caring for leather areas

Toyota recommends cleaning the interior of the vehicle at least twice a year to
maintain the quality of the vehicle's interior.

■

Shampooing the carpets

There are several commercial foaming-type cleaners available. Use a sponge
or  brush  to  apply  the  foam.  Rub  in  overlapping  circles.  Do  not  use  water.
Wipe dirty surfaces and let them dry. Excellent results are obtained by keep-
ing the carpet as dry as possible.

■

Seat belts

Clean  with  mild  soap  and  lukewarm  water  using  a  cloth  or  sponge.  Also
check the belts periodically for excessive wear, fraying or cuts.

WARNING

■

Water in the vehicle

●

Do  not  splash  or  spill  liquid  in  the  vehicle,  such  as  on  the  floor,  in  the
hybrid battery (traction battery) air vent, and in the trunk.
Doing so may cause the hybrid battery, electrical components, etc. to mal-
function or catch fire.

●

Do not get any of the SRS components or wiring in the vehicle interior wet. 
(



P. 36)

An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.

●

Vehicles with wireless charger: 
Do not let the wireless charger (



P. 366) get wet. Failure to do so may

cause the charger to become hot and cause burns or could cause electric
shock resulting in death or serious injury.

■

Cleaning the interior (especially instrument panel)

Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.

●

Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.

■

Preventing damage to leather surfaces

Observe the following precautions to avoid damage to and deterioration of
leather surfaces:

●

Remove any dust or dirt from leather surfaces immediately.

●

Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.

●

Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.

■

Water on the floor

Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components such as the audio system above or
under the floor of the vehicle. Water may also cause the body to rust.

■

When cleaning the inside of the windshield

Do not allow glass cleaner to contact the lens. Also, do not touch the lens.
(



P. 237)

■

Cleaning the inside of the rear window

●

Do  not  use  glass  cleaner  to  clean  the  rear  window,  as  this  may  cause
damage to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe the
window in strokes running parallel to the heater wires or antenna.

●

Be careful not to scratch or damage the heater wires or antenna.

Before recharging

When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable  and  explosive.  Therefore,  observe  the  following  precautions  before
recharging:

●

If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.

●

Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.

■

After recharging/reconnecting the 12-volt battery

●

Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.

●

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 repeatedly or cannot 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.

■

Replacing tires and wheels

If the ID codes of the tire pressure warning valve and transmitters are not

registered, the tire pressure warning system will not work properly. In this

case, after driving for about 20 minutes, the tire pressure warning light will

blink for approximately 1 minute and then illuminate to indicate a system

malfunction.

■

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 is not obvious.

■

Routine tire inflation pressure checks

The  tire  pressure  warning  system  does  not  replace  routine  tire inflation

pressure  checks.  Make  sure  to  check  tire  inflation  pressure  as  part  of

your routine of daily vehicle checks.

■

Low profile tires (vehicles with 18 or 19-inch wheels)

Generally,  low  profile  tires  will  wear  more  rapidly  and  tire  grip  perfor-

mance  will  be  reduced  on  snowy  and/or  icy  roads  when  compared  to

standard tires. Be sure to use snow tires on snowy and/or icy roads and

drive carefully at a speed appropriate for road and weather conditions.

■

Maximum load of tire

Check that the maximum load 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. (

Tire types

●

Summer tires
Summer tires are high-speed performance 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

driving  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 provide better traction in snow and to

be  adequate  for  driving  in  most  winter  conditions  as  well  as  for  use

year-round. All  season  tires,  however,  do  not  have  adequate  traction

performance compared with snow tires in heavy or loose snow. Also, all

season tires fall short in acceleration 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  tires  as  original  equipment,  make  sure  your  snow

tires also have radial construction. Do not install studded tires without

first  checking  local  regulations  for  possible  restrictions.  Snow  tires

should be installed on all wheels. (

Situations in which the tire pressure warning system may not oper-

ate properly

●

In  the  following  situations,  the  tire  pressure  warning  system  may  not

operate properly.
• If non-genuine Toyota wheels are used. 

• If  a  tire  has  been  replaced  with  a  tire  that  is  not  an  OE  (Original

Equipment) tire.

• If a tire has been replaced with a tire that is not of the specified size.

• If tire chains, etc. are installed.

• If a window tint that affects radio wave signals is installed.

• If there is a lot of snow or ice on the vehicle, particularly around the

wheels or wheel housings.

• If the tire inflation pressure is much higher than the specified level.

• If wheels not equipped with tire pressure warning valve and transmit-

ter are used.

• If the ID codes of the tire pressure warning valve and transmitters are

not registered in the tire pressure warning computer.

●

Performance may be affected in the following situations.
• When driving near a TV tower, electric power plant, gas station, radio

station,  large  display,  airport  or  other  facility  that  generates  strong

radio waves or electrical noise

• When  carrying  a  portable  radio,  cellular  phone,  cordless  phone  or

other wireless communication device

If  tire  position  information  is  not  correctly  displayed  due  to  the  radio

wave conditions, the display may be corrected by changing the location

of the vehicle as the radio wave conditions may change.

●

When the vehicle is stopped, the time taken for the warning to start or

turn off may be longer.

●

When the inflation pressure of a tire drops rapidly, for example when a

tire has burst, the warning may not operate.

■

Initialization procedure

●

Make sure to perform the initialization procedure after adjusting the tire

inflation pressure.

Also,  make  sure  the  tires  are  cold  before  performing  the  initialization

procedure or adjusting the tire inflation pressure.

●

If the power switch is turned off during initialization, it is not necessary to

restart  the  initialization  procedure  from  the  beginning  as  it  will  begin

automatically when the power switch is turned back to ON mode.

●

If  initialization  has  accidentally  been  started  when  it  is  not  necessary,

adjust the tire inflation pressure to the specified level when the tires are

cold and then perform the initialization procedure again.

●

While the position of each tire is being determined and the inflation pres-

sures  are  not  being  displayed  on  the  multi-information  display,  if  the

inflation pressure of a tire drops, the tire pressure warning light will come

Warning performance of the tire pressure warning system

The  warning  of  the  tire  pressure  warning  system  will  change  in  accor-

dance with the conditions under which it was initialized. For this reason,

the system may give a warning even if the tire pressure does not reach a

low enough level, or if the pressure is higher than the pressure that was

adjusted to when the system was initialized.

■

If the tire pressure warning system is not initialized properly

●

In the following situations, initialization may take longer than usual to be

completed or may not be possible. (Usually, the vehicle will need to be

driven for approximately 10 to 30 minutes to complete initialization.) 

If  initialization  is  not  complete  after  driving  approximately  30  minutes,

continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to com-

plete initialization.

• If  the  vehicle  is  backed  up  while  performing  initialization,  data  col-

lected during initialization will be cleared and it will take longer than

normal to complete.

• If the vehicle is driven in heavy traffic or another situation where other

vehicles are driven close by, it may take time for the system to recog-

nize the tire pressure warning valve and transmitters of your vehicle

over those of other vehicles.

If  initialization  is  not  complete  after  driving  for  approximately  1  hour,

park the vehicle in a safe place for approximately 20 minutes and then

drive the vehicle again.

●

In  the  following  situations,  initialization  will  not  be  started  or  was  not

completed  properly  and  the  system  will  not  operate  properly.  Perform

the initialization procedure again.
• If, when attempting to start initialization, the tire pressure warning light

does not blink 3 times.

• If, when the vehicle has been driven for about 20 minutes after per-

forming initialization, the tire pressure warning light blinks for approxi-

mately 1 minute and then illuminates.

●

If  initialization  cannot  be  completed  after  performing  the  above  proce-

dure, contact your Toyota dealer.

■

When registering ID codes

●

Before performing ID code registration, make sure that no wheels with

tire pressure warning valve and transmitters installed are near the vehi-

cle.

●

Make sure to initialize the tire pressure warning system after registering

the ID codes. If the system is initialized before registering the ID codes,

the initialized values will be invalid.

●

As the tires will be warm when registration is completed, make sure to

allow the tires to cool before performing initialization.

Canceling ID code registration

●

To cancel ID code registration after it has been started, turn the power

switch off before driving the vehicle.

If the vehicle is driven after ID code registration is started, to cancel reg-

istration, perform the ID code registration start procedure again and turn

the power switch off before driving.

●

If ID code registration has been canceled, the tire pressure warning light

will blink for approximately 1 minute when the power switch is turned to

ON mode and then illuminate. The tire pressure warning system will be

operational when the tire pressure warning light turns off.

●

If  the  warning  light  does  not  turn  off  even  after  several  minutes  have

elapsed, ID code registration may not have been cancelled correctly. To

cancel  registration,  perform  the  ID  code  registration  start  procedure

again and then turn the power switch off before driving.

■

If ID codes are not registered properly

●

In  the  following  situations,  ID  code  registration  may  take  longer  than

usual to be completed or may not be possible. (Usually, the vehicle will

■

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.

NOTICE

■

Repairing  or  replacing  tires,  wheels,  tire  pressure  warning  valve

and transmitters and tire valve caps

●

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

valve and transmitters, contact your Toyota dealer as the tire pressure

warning  valve  and  transmitters  may  be  damaged  if  not  handled  cor-

rectly.

●

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

installed, water may enter the valves of the tire pressure warning valve

and transmitters and the valves may become stuck.

●

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 valve 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. Make sure to replace the tire pressure warning valve and

transmitter when replacing the tire. (



P. 417)

■

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 18 or 19-inch wheels)

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

when sustaining 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 potholes, uneven pavement, curbs and other road hazards. Fail-

ure to do so may 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.

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.

6-3. Do-it-yourself maintenance

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.

■

When replacing wheels

The wheels of your vehicle are equipped with tire pressure warning valve

and  transmitters  that  allow  the  tire  pressure  warning  system  to  provide

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

ever  wheels  are  replaced,  tire  pressure  warning  valve  and  transmitters

must be installed. (



P. 417)

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.

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.

NOTICE

■

Replacing tire pressure warning valve and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-

ing  valve  and  transmitters, make sure to have tires serviced  by your

Toyota dealer or other qualified service shop. In addition, make sure to

purchase  your  tire  pressure  warning  valve  and  transmitters  at  your

Toyota dealer.

●

Ensure that only genuine Toyota wheels are used on your vehicle.

Tire  pressure  warning  valve  and  transmitters  may  not  work  properly

with non-genuine wheels. 

●

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.
