1998 TOYOTA 4RUNNER traction control

4RUNNER (1998)
Use the front drive control lever to
select the following transfer modes.
ºH2º (high speed position, two-
wheel drive): Lever at ºH2º
Use this for normal driving on dry
hardsurfaced roads. This position
gives greater economy, quietest ride
and least wear.
ºH4º (high speed position, four-
wheel drive): Lever at ºH4º
Use this for normal driving on wet, icy
or snow- covered roads. This position
provides greater traction than two-
wheel drive. ºNº (neutral position):
Lever at ºNº
No power is delivered to the wheels.
The vehicle must be stopped.
ºL4º (low speed position, four-
wheel drive): Lever at ºL4º
Use this for maximum power and trac-
tion. Use ºL4º for climbing or des-
cending steep h ills, off- road driving,
and hard pulling in s and, mud or deep
snow.
The four- wheel drive indicator light
comes on when the ºH4º, ºNº or ºL4º
mode is selected.
See º(c) Shifting procedure (lever
type)º for further instructions. (a) Front drive control
(lever/button type)

4RUNNER (1998)
Use the front drive control lever
and º4WDº button to select the fol-
lowing transfer modes.
ºH2º (high speed position, two-
wheel drive): Lever a ºHº, º4WDº but-
ton left out
Use this for normal driving on dry
hardsurfaced roads. This position
gives greater economy, quietest ride
and least wear.
ºH4º (high speed position, four-
wheel drive): Lever at ºHº, º4WDº
button pushed in
Use this for normal driving on wet, icy
or snow- covered roads. This position
provides greater traction than two-
wheel drive. ºNº (neutral position):
Lever at ºNº
No power is delivered to the wheels.
The vehicle must be stopped.
ºL4º (low speed position, four-
wheel drive): Lever at ºL4º
Use this for maximum power and trac-
tion. Use ºL4º for climbing or des-
cending steep h ills, off- road driving,
and hard pulling in s and, mud or deep
snow.
The four- wheel drive indicator light
comes on when the ºH4º, ºNº or ºL4º
mode is selected.
See º(c) Shifting procedure (lever/but-
ton type)º for further instructions. (b) A.D.D. (automatic

NOTICE
You should not attempt to remove
the theft prevention labels as itmay violate certain state or feder-al laws.
Suspension and chassis
CAUTION
Do not modify the suspension/
chassis with lift kits, spacers,
springs, etc. It can cause danger-
ous handling characteristics re-
sulting in loss of control.
Types of tires
Determine what kind of tires your
vehicle is originally equipped with.
1. Summer tires
Summer tires are high- speed capabili-
ty tires best suited to highway driving
under dry conditions.
Since summer tires do not have the
same traction performance as snow
tires, summer tires are inadequate for
driving on snow- covered or icy roads.
For driving on snow- covered or icy
roads, we recommend using snow
tires. If installing snow tires, be sure
to replace all four tires. 2. All season tires
All season tires are designed to pro-
vide better traction in snow and to be
adequate for driving in most winter
conditions, as well as for use all year
round.
All season tires, however, do not have
adequate traction performance
compared with snow tires in heavy or
loose snow. Also, all season tires fall
short in acceleration and handling per-
formance compared with summer tires
in highway driving.

4RUNNER (1998)
To equalize tire wear and help ex-
tend tire life, Toyota recommends
that you rotate your tires approxi-
mately every 12000 km (7500 miles).
However, the most appropriate tim-
ing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See ºIf you have a flat tireº in Part
4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is
usually caused by incorrect tire pres-
sure, improper wheel alignment, out-
of- balance wheels, or severe braking. WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recom-
mended when driving on snow or
ice.
On wet or dry roads, conventional
tires provide better traction than snow
tires.
SNOW TIRE SELECTION
If you need snow tires, select the
same size, construction and load
capacity as the original tires on
your Toyota.
Do not use tires other than those
mentioned above. Do not install
studded tires without first checking lo-
cal regulations for possible restric-
tions.SNOW TIRE INSTALLATION
Snow tires should be installed on
all wheels.
Installing snow tires on the front
wheels only can lead to an excessive
difference in road grip capab
ility be-
tween the front and rear tires which
could cause loss of vehicle control.
When storing removed tires, you
should store them in a cool dry place.
Mark the direction of rotation and be
sure to install them in the same direc-
tion when replacing.

Uniform tire quality grading
This information has been prepared in
accordance with regulations issued by
the National Highway Traffic Safety
Administration of the U.S. Department
of Transportation. It provides the pur-
chasers 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
vehicle tires must conform to Fed-
eral Safety Requirements in addition
to these grades. These quality
grades are molded on the sidewall.
Treadwear ÐThe treadwear 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 conditions of
their use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices and differences in road char-
acteristics and climate. Traction A, B, C
ÐThe traction
grades, from highest to lowest, are A,
B, and C, and they represent the
tire's ability to stop on wet pavement
as measured under controlled condi-
tions 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 (turning)
traction.
Temperature A, B, C ÐThe tempera-
ture grades are A (the highest), B,
and C, representing the tire's resis-
tance to the generation of heat and its
ability to dissipate heat when tested
under controlled conditions on a speci-
fied indoor laboratory test wheel. Sus-
tained high temperature can cause the
material of the tire to degenerate and
reduce tire life, and excessive temper-
ature can lead to sudden tire failure.
The grade C corresponds to a level of
performance which all passenger car
tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher lev-
els of performance 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 properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire failure.
