Whe

n tr

ouble

rises

Stop the EV system. Set the
parking brake and shift the
shift position to P.

Remove the mud, snow or
sand from around the stuck
tire.

Place wood, stones or some
other material under the front
wheels to help provide trac-
tion.

Restart the EV system

Shift the shift position to D or
R and release the parking
brake. Then, while exercising
caution, depress the acceler-
ator pedal.

When it is difficult to free the

vehicle

Press

WARNING

●

Keep hands and clothing (espe-

cially a tie, a scarf or a muffler)

away from the fan. Failure to do

so may cause the hands or

clothing to be caught, resulting

in serious injury.

●

Do not loosen the coolant reser-

voir cap while the EV system

and radiator are hot. High tem-

perature steam or coolant could

spray out.

NOTICE

■

When adding coolant

Add coolant slowly after the EV

system has cooled down suffi-

ciently. Adding cool coolant to a

hot EV system too quickly can

cause damage to the EV system.

■

To prevent damage to the

cooling system

Observe the following precau-

tions:

●

Avoid contaminating the coolant

with foreign matter (such as

sand or dust, etc.).

●

Do not use water or any other

coolant when refilling coolant.

Also, do not use any additive

agents for the coolant.

If the vehicle becomes

stuck

Carry out the following pro-
cedures if the tires spin or
the vehicle becomes stuck
in mud, dirt or snow:

8-2. Steps to take in an emergency

WARNING

■

When attempting to free a

stuck vehicle

If you choose to push the vehicle

back and forth to free it, make

sure the surrounding area is clear

to avoid striking other vehicles,

objects or people. The vehicle

may also lunge forward or lunge

back suddenly as it becomes free.

Use extreme caution.

■

When shifting the shift posi-

tion

Be careful not to shift the shift

position with the accelerator pedal

depressed.
This may lead to unexpected

rapid acceleration of the vehicle

that may cause an accident

resulting in death or serious injury.

NOTICE

■

To avoid damaging the trans-

mission and other compo-

nents

●

Avoid spinning the tires and

depressing the accelerator

pedal more than necessary.

●

If the vehicle remains stuck

even after these procedures are

performed, the vehicle may

require towing to be freed.

Your Toyota dealer will help answer

■

DOT quality grades

All passenger vehicle tires must
conform to Federal Safety
Requirements in addition to
these grades. Quality grades
can be found where applicable
on the tire sidewall between
tread shoulder and maximum
section width.

For example: Treadwear 200 Trac-
tion AA Temperature A

■

Treadwear

The treadwear grade is a com-
parative rating based on the
wear rate of the tire when tested
under controlled conditions on a
specified government test
course.

For example, a tire graded 150
would wear one and a half (1 - 1/2)
times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. Performance may differ
significantly from the norm due to
variations in driving habits, service
practices and differences in road
characteristics and climate.

■

Traction AA, A, B, C

The traction grades, from high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement

as measured under controlled
conditions on specified govern-
ment test surfaces of asphalt
and concrete.

A tire marked C may have poor
traction performance.
Warning: The traction grade
assigned to this tire is based on
braking (straight ahead) traction
tests and does not include corner-
ing (turning) traction.

■

Temperature A, B, C

The temperature grades are A
(the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory test wheel.

Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume that it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause

heat buildup and possible tire fail-

ure.
