tem)

The engine may not start. Follow the procedure below to initialize the system.

Shift the shift lever to P.
Open and close any of the doors.
Restart the engine.

●

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

●

Start the engine with the engine switch in ACCESSORY mode. The engine
may not start when the engine switch turned from off. However, the engine
will operate normally from the second attempt.

●

The engine switch mode is recorded by the vehicle. If the battery is recon-
nected, the vehicle will return the engine switch mode to the status it was in
before  the  battery  was  disconnected.  Make  sure  to  turn  off  the  engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.

If the system will not start even after multiple attempts, contact your Toyota
dealer.

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 code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing  for  about  20  minutes,  the  tire  pressure  warning  light  blinks  for  1
minute and stays on 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.

■

Maximum load of tire

Check that the number 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. (

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. (



P. 329)

■

If the tread on snow tires wears down below 0.16 in. (4 mm)

The effectiveness of the tires as snow tires is lost.

■

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.

●

In the following cases, the tire pressure warning system may not operate

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

• A tire has been replaced with a tire that is not an OE (Original Equip-

ment) tire.

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

• Tire chains etc. are equipped.

• If a window tint that affects the 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  extremely  higher  than  the  specified

level.

• If  the  spare  tire  is  in  a  location  subject  to  poor  radio  wave  signal

reception.

• If a large metallic object which can interfere  with signal reception is

put near the spare tire.

• If tires not equipped with the tire pressure warning valves and trans-

mitters are used.

• If the ID code on the tire pressure warning valves and transmitters is

not registered in the tire pressure warning computer.

●

Performance may be affected in the following situations.
• 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

Also, make sure the tires are cold before carrying out initialization or tire

inflation pressure adjustment.

●

If you have accidentally turned the engine switch to the “LOCK” position

(vehicles without a smart key system) or off (vehicles with a smart key

system) during initialization, it is not necessary to press the reset switch

again  as initialization will restart automatically  when the engine  switch

has been turned to the “ON” position (vehicles without a smart key sys-

tem) or IGNITION ON mode (vehicles with a smart key system) for the

next time.

●

If you accidentally press the reset switch when initialization is not neces-

sary,  adjust  the  tire  inflation  pressure  to  the  specified  level  when  the

tires are cold, and conduct initialization 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

When initialization of the tire pressure warning system has failed

●

Do  not  move  the  vehicle  backward  during  initialization.  Initialization  is

started again from the beginning and it may take longer than usual.

●

Initialization may take longer to complete if the vehicle is driven on an

unpaved road.

When  performing  initialization,  drive  on  a  paved  road  if  possible.

Depending on the driving environment and condition of the tires, initial-

ization will be completed in approximately 10 to 30 minutes.
• If initialization is not complete after driving approximately 30 minutes,

continue driving for a while.

• If initialization is not complete after driving approximately 1 hour, park

the vehicle in a safe place for approximately 20 minutes. Then drive

straight (with occasional left and right turns) at approximately 25 mph

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. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. (

■

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.

■

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.

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.

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.

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. 425)

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, lead-
ing 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 valves and transmitters

●

Because tire repair or replacement may affect the tire pressure warn-
ing valves 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  valves  and  transmitters  at  your
Toyota dealer.

●

Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.
