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. 125)
When the child becomes large enough to properly wear the vehicle's seat
belt, follow the instructions on P. 66 regarding seat belt usage.
Seat belt pretensioners
Seat belt pretensioners are not designed to activate in minor frontal or
side impacts, 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, use only
genuine Toyota parts.
If either front seat belt does not retract or cannot be pulled out due to a
malfunction or activation of the pretensioner, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional as soon as possible.
If the front seat belt retractor assembly or surrounding area has been
damaged, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional as soon as possible.
When you sell your vehicle, we urge you to explain to the buyer that it
has seat belt pretensioners by alerting the buyer to the contents of this
section.

FT86_EE
CAUTION
When the VSC is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
When the TRC/VSC systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to ensure vehicle stability and driving force,
do not turn the TRC/VSC systems off unless necessary.
Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRC and VSC systems will not function correctly if different tires
are installed on the vehicle.
Contact any authorized Toyota dealer or repairer, or another duly qualified
and equipped professional for further information when replacing tires or
wheels.
Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Regulations on the use of tire chains
Regulations regarding the use of tire chains vary according to loca-
tion and type of road. Always check local regulations before installing
chains.
Tire chains
Observe the following precautions when installing and removing chains.
Install and remove tire chains in a safe location.
Install tire chains on the rear tires. Do not install tire chains on front tires.
Install tire chains on rear tires as tightly as possible. Retighten chains
after driving approximately 100 m (328 ft.).
Install tire chains following the instructions provided with the tire chains.
CAUTION
Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
Use tires of the specified size, and that are the same size, same maker,
same brand and tread pattern.
Maintain the recommended level of air pressure.
Do not drive at speeds in excess of the speed limit or the speed limit spec-
ified for the snow tires being used.
Use snow tires on all, not just some wheels.

FT86_EE
When to replace your vehicle’s tires
Tires should be replaced if:
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.
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.
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.
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is car-
ried out approximately every
10000 km (6000 miles).

CAUTION
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.
Make sure to install 4 tires that are of the specified size, and that all 4 tires
are the same size, same maker, same brand and tread pattern.
Do not use tire sizes other than those recommended by Toyota.
Only use radial 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.
NOTICE
Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire air pressure, reducing the cush-
ioning ability of the tires. In addition driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.
Low profile tires and wheels (vehicles with 17-inch tires)
Low profile tires may cause greater damage than usual to the tire 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 pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

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.

CAUTION
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.

When trouble arises
FT86_EE
The valve of a tire that has been repaired
After a tire is repaired with the emergency tire puncture repair kit, the valve
should be replaced.
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 Toyota 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.
