(j) Driving in º2nd STRTº (second
start) mode
In the º2nd STRTº (Second start) mode,
the transmission system shifts up from
second gear. Use this mode when starting
your vehicle in sand, mud, ice or snow.
To set the º2nd STRTº mode, push the
º2ndº button. In the º2nd STRTº mode, the
º2nd STRTº indicator light comes on.
The ºPWRº mode is automatically can-
celled when you push the º2ndº button.
Use the four- wheel drive control lever
and center differential lock button to
select the transfer and center differen-
tial modes.
The ºHº position of the four- wheel drive
control lever provides either lock or unlock
mode of the center differential depending
on the center differential lock button posi-
tion.
ºHº (high speed position, center differ-
ential unlocked): Lever at ºHº, center dif-
ferential lock button left out
Use this for normal driving on all types of
roads, from dry hard- surfaced roads to
wet, icy or snow- covered roads. This
position gives greater economy, quietest
ride, least wear and better vehicle control. ºHº (high speed position, center differ-
ential locked):
Lever at ºHº, center differ-
ential lock button pushed in
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the center differential
unlock mode.
ºNº (neutral position): Lever at ºNº
No power is delivered to the wheels. Use
this position only for operating a winch or
other equipment. The vehicle must be
stopped.
ºLº (low speed position, center differen-
tial locked): Lever at ºLº
Use this for maximum power and traction.
Use ºLº for hard pulling in situations the
vehicle cannot negotiate even in the ºHº
(lock) mode.
The indicator light tells when the differen-
tial lock is engaged. Note that the differ-
ential is not still locked as long as the
indicator light remains off.
If the indicator light does not go off when
you push out the center differential lock
button, drive straight ahead while acceler-
ating or decelerating, or drive in reverse.
See º(b) Shifting procedureº for further in-
structions.

Uniform tire quality grading
This information has been prepared in ac-
cordance with regulations issued by the
National Highway Traffic Safety Adminis-
tration of the U.S. Department of Trans-
portation. It provides the purchasers and/
or prospective purchasers of Toyota
vehicles with information on uniform tire
quality grading.
Your Toyota dealer will help answer any
questions you may have as you read this
information.
DOT quality gradesÐAll passenger ve-
hicle tires must conform to Federal
Safety Requirements in addition to
these grades. These quality grades are
molded on the sidewall.
Tread wearÐ
The tread wear grade is a
comparative 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 condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics and climate. Traction AA, A, B, CÐ
The traction
grades, from highest to lowest, are AA, A,
B, and C, and they represent the tire's
ability to stop on wet pavement as mea-
sured under controlled conditions on spe-
cified 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 (turning) traction.
Temperature A, B, CÐ The temperature
grades are A (the highest), B, and C,
representing the tire's resistance to the
generation of heat and its ab ility to dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el 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 perfor-
mance on the laboratory test wheel than
the minimum required by law. Warning: The temperature grades for this
tire are established for a tire that is prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.
