1998 TOYOTA T100 transmission

T100(U)
68
Vehicles with cruise control–When the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease
the vehicle speed, see ”Cruise control” in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using ”2” and ”L” positions
The ”2” and ”L” positions are used for
strong engine braking as described pre-
viously.
With the selector lever in ”2” or ”L”, you
can start the vehicle in motion as with the
lever in ”D”.
With the selector lever in ”2”, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ”L”, the trans-
mission is engaged in the first gear.
NOTICE

Be careful not to overrev the en-
gine. Watch the tachometer to keep
engine rpm from going into the red
zone. The approxmate maximum al-
lowable speed for each position is
given below for your reference:
Two-wheel drive models—
”2” 100 km/h (62 mph)
”L” 55 km/h (34 mph)
Four-wheel drive models—
—Four-wheel drive control lever
in ”H2” and ”H4” ”2” 100 km/h (62 mph)
”L” 55 km/h (34 mph)
—Four-wheel drive control lever
in ”L4” ”2” 35 km/h (21 mph)
”L” 20 km/h (12 mph)
Do not continue hill climbing for a
long time in the ”2” or ”L” posi-
tion. This may cause severe auto-
matic transmission damage from
overheating. To prevent such dam-
age, use ”D” position for hill climb-
ing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with your foot, shift the selector lever to the
”R” position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop. Pull the parking brake lever up fully to
securely apply the parking brake.
With the brake pedal pressed down,
shift the selector lever to the ”P” posi-
tion.
CAUTION
While the vehicle is moving, never
attempt to move the selector lever
into ”P” position under any circum-
stances. Serious mechanical damage
and loss of vehicle control may re-
sult.

T100(U)69
(f) Good driving practice
If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
should be turned off. Be sure to turn
the switch on immediately afterward.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
CAUTION
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping.
NOTICE
Do not hold the vehicle on an up-
grade with the accelerator pedal. It
can cause the transmission to over-
heat. Always use the brake pedal or
parking brake.
(g) Rocking your vehicle if stuck
CAUTION
To rock your vehicle if it becomes
stuck in snow, mud, sand, etc., first
check that there are no objects or
people around the vehicle. During the
rocking operation the vehicle may
suddenly move forward or backward
as it becomes unstuck, causing injury
or damage to nearby people or ob-
jects.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts. Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,
consider other ways such as tow-
ing.

Manual transmission
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving,
because it will cause clutch trouble. And
do not use the clutch to hold the vehicle
when stopped on an uphill grade–use the
parking brake.
Recommended shifting speeds
The transmission is fully synchronized and
upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the following
speeds:

Upshifting too soon or downshifting too
late will cause lugging, and possibly ping-
ing. Regularly revving the engine to maxi-
mum speed in each gear will cause ex-
cessive engine wear and high fuel
consumption.
Maximum allowable speeds
To get on a highway or to pass slower
traffic, maximum acceleration may be nec-
essary. Make sure you observe the follow-
ing maximum allowable speeds in each
gear:
Two-wheel drive models 1-ton models

NOTICE
Do not downshift if you are going
faster than the maximum allowable
speed for the next lower gear.
Good driving practice
If it is difficult to shift into reverse, put
the transmission in neutral, release the
clutch pedal momentarily, and then try
again.
When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the fifth gear.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
NOTICE
Make sure the vehicle is completely
stopped before shifting into reverse.
The four-wheel drive control lever se-
lects one of the transfer modes below
by the position.
The ”4WD” indicator light shows when the
four-wheel drive control lever is in the
”H4”, ”N” or ”L4” position.
”H2” (high speed position, two-wheel
drive): Lever at ”H2”
Use this for normal driving on dry hard-
surfaced roads. This position gives greater
economy, quietest ride and least wear.
”H4” (high speed position, four-wheel
drive): Lever at ”H4”
Use this for normal driving on wet, icy or
snow-covered roads. This position pro-
vides greater traction than two-wheel
drive. Four-wheel drive system—

SHIFTING BETWEEN ”H2” AND ”H4”
To shift from ”H2” to ”H4”,
reduce your
speed to less than 80 km/h (50 mph) and
move the four-wheel drive control lever.
You need not even depress the clutch
pedal.
If you have trouble shifting in cold weath-
er, reduce your speed or stop the vehicle
and reshelf.
The indicator light may not come on even
if you shift into ”H4”. If the vehicle is
stopped, starting out the vehicle will turn
it on. If the vehicle is moving, depress or
release the accelerator pedal slightly.
CAUTION
Never move the four-wheel drive con-
trol lever if wheels are slipping. Stop
the slipping or spinning before shift-
ing.
To shift from ”H4” to ”H2”, simply move
the four-wheel drive control lever.
The vehicle may be moving at any speed.
You need not even depress the clutch
pedal. SHIFTING BETWEEN ”H4” AND ”L4”
To shift from ”H4” to ”L4”,

speed to less than 80 km/h (50 mph) and
move the four-wheel drive control lever.
If you have trouble shifting in cold weath-
er, reduce your speed or stop the vehicle
and reshift.
The indicator light may not come on even
if you shift into ”H4”. If the vehicle is
stopped, starting out the vehicle will turn
it on. If the vehicle is moving, depress or
release the accelerator pedal slightly.
CAUTION
Never move the four-wheel drive con-
trol lever if wheels are slipping. Stop
the slipping or spinning before shift-
ing.

Parking brake
To set: Pull out on the lever.
To release: Press the lock release but-
ton, turn the lever, and push it in.
Before leaving your vehicle, firmly apply
the parking brake. For better holding pow-
er, first depress the brake pedal and hold
it while setting the parking brake.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.
Cruise control
The cruise control allows you to cruise
the vehicle at a desired speed over 40
km/h (25 mph) even with your foot off
the accelerator pedal.
Your cruising speed can be maintained up
or down grades within the limits of engine
performance, although a slight speed
change may occur when driving up or
down the grades. On steeper hills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION

To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow-covered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.
TURNING ON THE SYSTEM
To operate the cruise control, push the
”CRUISE ON-OFF” switch. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another push on the switch will
turn the system completely off.

T100(U)75
CAUTION
To avoid accidental cruise control en-
gagement, keep the ”CRUISE ON-
OFF” switch off when not using the
cruise control.
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in ”D” before
you set the cruise control speed.
Bring your vehicle to the desired speed,
push the lever down in the ”SET/COAST”
direction and release it. This sets the ve-
hicle at that speed. If the speed is not
satisfactory, tap the lever up for a faster
speed, or tap it down for a slower speed.
Each tap changes the set speed by 1.6
km/h (1.0 mph). You can now take your
foot off the accelerator pedal.
If you need acceleration—for example,
when passing–depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CAUTION
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-
ving.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the control lever in the ”CAN-CEL” direction and release it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual transmission).
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity. RESETTING AT A FASTER SPEED
Press the control lever upward in the
”RES/ACC” direction and hold it. Release
the lever when the desired speed is at-
tained. While the lever is held upward, the
vehicle will gradually gain speed.
However, a faster way to reset is to ac-
celerate the vehicle and then press the
control lever downward in the ”SET/
COAST” direction.
RESETTING AT A SLOWER SPEED
Press the control lever downward in the
”SET/COAST” direction and hold it. Re-
lease the lever when the desired speed is
attained. While the lever is held, the ve-
hicle speed will gradually decrease.
However, a faster way to reset is to de-
press the brake pedal and then press the
control lever downward in the ”SET/
COAST” direction.
On vehicles with automatic transmission,
even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. To decrease the
vehicle speed, reset to a slower speed
with the cruise control lever or depress
the brake pedal. If you use the brake
pedal, cruise control is cancelled.

T100(U)
76
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the ”RES/ACC” direction will
restore the speed set prior to cancellation.
However, once the vehicle speed falls be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
CRUISE CONTROL FAILURE WARNING
If the ”CRUISE” indicator light in the
instrument cluster flashes when using the
cruise control, there is some trouble in the
cruise control system. Contact your Toyota
dealer and have your vehicle inspected.
To crank the engine without depressing
the clutch pedal, push the switch with
the ignition on.
The switch stays on as long as the igni-
tion is on. And it will automatically turn off
when the ignition is off.
This switch cancels the clutch start sys-
tem, which is designed to keep the starter
motor from operating if the clutch pedal is
not depressed all the way down.
The switch allows the vehicle to be driven
out of difficult situations by cranking the
engine with the clutch engaged.
Never use the switch for normal engine
starting. Be sure to follow the starting
procedure instructed in ”How to start the
engine” in Part 3.
