5-2. Steps to take in an emergency
If the vehicle becomes stuck
■Emergency hook
Carry out the following procedures if the tires spin or the vehicle
becomes stuck in mud, dirt, or snow.
Stop the engine. Set the parking brake and put the shift
lever in P.
Remove the mud, snow, or sand from around the stuck tire.
Place wood, stones or some other material to help provide
traction under the tires.
Restart the engine.
Shift the shift lever to D or R and carefully apply the accel-
erator to free the vehicle.
Turn off the TRAC and/or VSC systems if it is difficult to get out
because of TRAC and/or VSC operation. ( P. 142)
When your vehicle becomes stuck and
cannot move, the emergency hook is
used for another vehicle to pull your vehi-
cle out in an emergency.
Your vehicle is not designed to tow
another vehicle.

CAUTION
■When replacing tires and wheels
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to the peripheral parts of the tires,
as well as dangerous handling characteristics, which may lead to fatal or
injury accidents.
Do not use tire sizes or wheel sizes other than those recommended by
Scion.

Uniform Tire Quality GradingThis information has been prepared in accordance with regulations
issued by the National Highway Tr affic Safety Administration of the
U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers of Scion
vehicles with information on uniform tire quality grading.
Your Scion dealer will help answer any questions you may have as
you read this information.
■ DOT quality grades
All passenger vehicle tires mu st 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 Traction AA Temperature A

336 6-1. Specifications
■Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied 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 diff er 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 highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
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 cornering (turn-
ing) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory 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 Federal 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.
