because visibility will be reduced,
the windows may become fogged-
up, and the road will be slippery.
●Drive carefully whe n it starts to
rain, because the road surface will
be especially slippery.
●Refrain from high speeds when
driving on an expressway in the
rain, because there may be a
layer of water between the tires
and the road surface, preventing
the steering and brakes from
operating properly.

obtain a good Eco score.
●When starting off:
Gradually depress the accelerator
pedal to stay withi n the zone of Eco
acceleration and accelerate to the
desired speed. By refraining from
excessive acceleration, a good eco
start score will be obtained.
●When driving:
After accelerating to the desired
speed, release the accelerator
pedal and drive at a stable speed
while staying within the zone of Eco
acceleration. By staying within the
zone of Eco acceleration, a good
eco cruise score will be obtained.
●When stopping:
By starting to release the accelera-
tor pedal early before decelerating,
a good eco stop score will be
obtained.
■Restraining the fuel cell system
output (Brake Override System)
●When the accelera tor and brake
pedals are depressed at the same
time, the fuel cell system output
may be restrained.
●A warning message is displayed

wear, such as excessive wear
on one side of the tread. New tread
Worn tread
Treadwear indicator
The location of treadwear indicators
is shown by a “TWI” or “ ” mark,
etc., molded into the sidewall of
each tire. Replace the tires if the treadwear
indicators are s
howing on a tire.
■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 can-
not 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.
■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.
■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, whi chever is greater.
For the GAWR, see the Certification
Label.

Maintenance and care
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■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 pres-
sure. Whenever wheels are
replaced, the tire pressure warning
valves and transmitters must be
installed. ( P.406)
WARNING
●Greater possibility of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing 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
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 trouble arises
8-2.Steps to take in an emergency
If your vehicle needs
to be towed
If towing is necessary, we
recommend having your
vehicle towed by your Toy-
ota dealer or commercial
towing service, using a
wheel-lift type truck or flat-
bed truck.
Use a safety chain system
for all towing, and abide by
all state/provincial and local
laws.
WARNING
Observe the following precau-
tions.
Failure to do so m ay result in
death or serious injury.
■When towing the vehicle
Be sure to transp ort the vehicle
with all four wheels raised off the
ground. If the vehicle is towed
with the tires co ntacting the
ground, the drivetrain and related
parts may be damaged, an acci-
dent may occur due to a change
in direction of the vehicle or elec-
tricity generated by the operation
of the motor may cause a fire to
occur depending o n the nature of
the damage or malfunction.
■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 eyelets,
cables or chains may become
damaged, broken debris may hit
people, and cause serious dam-
age.
●Do not perform any of the fol-
lowing as doing so may cause
the parking lock mechanism to
engage, locking the rear wheels
and possibly leading to an acci-
dent resulting in death or seri-
ous injury:
• Unfasten the driv er’s seat belt
and open the driver’s door.
