Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also
lock if you lean forward too quickly. A slow, easy motion will allow the belt to
extend so that you can move around fully.
■ Child seat belt usage
The seat belts of your vehicle are principally designed for persons of adult
size.
● Use a child restraint system appropriate for the child, until the child
becomes large enough to properly wear the vehicle's seat belt. ( →P. 136)
● When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 73 regarding seat belt usage.
■ Seat belt pretensioners

side impact, in side or rear impacts or in roll-over accidents.
● The following four components operate simultaneously.
• Seat belt pretensioner for driver
• Seat belt pretensioner for front passenger
• SRS frontal airbag for driver
• SRS frontal airbag for front passenger
● Pretensioners are designed to function on a one-time-only basis. In the
event that a pretensioner is activated, both the driver’s and front passen-
ger’s seat belt retractor assemblies must be replaced only by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped
professional. When replacing seat belt retractor assemblies for the front
seating positions, use only genuine Toyota parts equipped with a force

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 or 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 any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.
■ Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving
for about 10 minutes, the tire pressure warning light comes on after blinking
for 1 minute to indicate a system malfunction.
■ Tire life
Any tires over 6 years old must be checked by a qualified technician even if
they have seldom or never been used or damage is not obvious.
■ Routine tire inflation pressure checks
The tire pressure warning system does no t replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.
■ If the tread on snow tires wears down 4 mm (0.16 in.)
The effectiveness of snow tires is lost.
■ Low profile tires (vehicles with 17-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance
will be reduced on snowy and/or icy roads when compared to standard tires.
Be sure to use snow tires or tire chains on snowy and/or icy roads and drive
carefully at a speed appropriate for road and weather conditions.
■ If you press the tire pressure wa rning reset switch accidentally
If initialization is performed, adjust the ti re inflation pressure to the specified
level and initialize the tire pressure warning system again.

Wheels
If a wheel is bent, cracked or heavily corroded, it should be replaced.
Otherwise, the tire may separate from the wheel or cause loss of
handling control.
■ Wheel selection
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 any authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.
*: Conventionally referred to as “offset”.
Toyota does not recommend using:
● Wheels of different sizes or types
● Used wheels
● Bent wheels that have been straightened
■ Aluminum wheel precautions
●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 1600 km (1000 miles).
● Be careful not to damage the aluminum wheels when using
tire chains.
● Use only Toyota genuine balance weights or equivalent and a
plastic or rubber hammer when balancing your wheels.

Maintenance and care
86_EE (OM18071E)
■
When replacing wheels
The wheels of your Toyota 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, the tire pressure warning valves and transmitters must
be installed. ( →P. 343)
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 loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
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 acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
● Be sure to install the wheel nuts with
the tapered ends facing inward. Install-
ing the nuts with the tapered ends fac-
ing 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.

■
After a tire is repaired with the emergency tire puncture repair kit
●The tire pressure warning valve and transmitter should be replaced.
● Even if the tire inflation pressure is at the recommended level, the tire
pressure warning light may come on/flash.
■ Note for checking the emergency tire puncture repair kit
Check the sealant expiry date occasionally.
The expiry date is shown on the bottle. Do not use sealant whose expiry
date has already passed. Otherwise, repairs conducted using the emer-
gency tire puncture repair kit may not be performed properly.
■ Emergency tire puncture repair kit
●The sealant stored in the emergency tire puncture repair kit can be used
only once to temporarily repair a single tire. If the sealant has been used
and needs to be replaced, purchase a new bottle at any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional. The compressor is reusable.
● The sealant can be used when the outside temperature is -40°C (-40°F)
or more.
● The repair kit is exclusively designed for size and type of tires originally
installed on your vehicle. Do not use it for tires that a different size than
the original ones, or for any other purposes.
● The sealant has a limited lifespan. The expiry date is marked on the bot-
tle. The bottle of sealant should be replaced with a new bottle before the
expiry date. Contact any authorized To yota dealer or repairer, or another
duly qualified and equipped professional for replacement.
● If the sealant gets on your clothes, it may stain.
● If the sealant adheres to a wheel or the surface of the vehicle body, the
stain may not be removable if it is not cleaned at once. Immediately wipe
away the sealant with a wet cloth.
● During operation of the repair kit, a loud operation noise is produced.
This does not indicate a malfunction.
● Do not use to check or to adjust the tire pressure.
