(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 otherparts.
Do not depress the accelerator ped-al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reversegear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck afterrocking the vehicle several times,
consider other ways such as tow-ing.
(h) If you cannot shift the selector le-
ver out of ºPº position
If you cannot shift the selector lever from
the ºPº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see ºIf
you cannot shift automatic transmission
selector leverº in Part 4.

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 cont rol is not cancelled. For ways to decrease the vehicle speed, see

(electronically controlled typeÐtwo- wheel drive models except
Pre Runner)

'98 Tacoma (U)81
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the selector
lever pulled toward you).
(a) Normal driving
1. Start the engine as instructed in ºHow to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
2. With your foot holding down the brake pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, the
transmission will not shift into the over-
drive gear even with the overdrive switch on.
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the º2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than 131 km/h (81
mph), and more powerful engine brak-
ing will be obtained.
Shift into the ºLº position. The trans-
mission will downshift to the first gear
when the vehicle speed drops down to
or lower than 63 km/h (39 mph), and
maximum engine braking will be ap-
plied. 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 ºCruise controlº in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of ºPº position when the
brake pedal is depressed (with the ignition
switch in ºONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in ºHow to start the engineº in Part 3. The
transmission must be in ºPº or ºNº.
When the front drive control lever is in
ºL4º (low-speed position, four-wheel drive),
the driving pattern selector setting has no
effect on gear shift timing. (See ºFour-
wheel drive systemº in this Chapter for
information of the front drive control le-
ver.) 2. With your foot holding down the brake pedal, shift the selector lever to ºDº.
In ºDº position, the automatic transmission
system will select the most suitable gear
for running conditions such as normal
cruising, hill climbing, hard towing, etc. Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low or
when the front drive control lever is in
ºL4º (low-speed position, four-wheel drive),
the transmission will not shift into the ov-
erdrive gear even with the overdrive
switch on. (See ºFour-wheel drive systemº
in this Chapter for information of the front
drive control lever.)
CAUTION
Never put your foot on the accelera-
tor pedal while shifting.
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift
the transmission as follows: Turn off the overdrive switch. The ºO/D
OFFº indicator light will come on and
the transmission will downshift to the
third gear.
Shift into the º2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the following
speed, and more powerful engine brak-
ing will be obtained.

Shift into the ºLº position. The trans-
mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the following speed, and
maximum engine braking will be ap-
plied.

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 ºCruise controlº in
this chapter.
CAUTION
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin or
skid.
(c) Using º2º and ºLº positions
The º2º and ºLº positions are used for
strong engine braking as described pre-
viously.
With the selector lever in º2º or ºLº, you
can start the vehicle in motion as with the
lever in ºDº.
With the selector lever in º2º, the vehicle
will start in the first gear and automatical-
ly shift to the second gear.
With the selector lever in ºLº, the trans-
mission is engaged in the first gear.
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to keepengine rpm from going into the redzone. The approximate maximum al-
lowable speed for each position isgiven below for your reference:

Do not continue hill climbing for a
long time in the º2º or ºLº posi-
tion. This may cause severe auto-matic transmission damage from overheating. To prevent such dam-
age, use ºDº 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
ºRº position.
NOTICE
Never shift into reverse while the ve-
hicle is moving.

NOTICE
If you rock your vehicle, observe the following precautions to prevent dam-age to the transmission and otherparts.
Do not depress the accelerator ped-al while shifting the selector lever or before the transmission is com-
pletely shifted to forward or reversegear.
Do not race the engine and avoidspinning the wheels.
If your vehicle remains stuck after
rocking the vehicle several times,consider other ways such as tow-
ing.
(i) If you cannot shift the selector le- ver out of ºPº position
If you cannot shift the selector lever from
the ºPº position even though the brake
pedal is depressed, use the shift lock
override lever. For instructions, see ºIf you
cannot shift automatic transmission selec-
tor leverº in Part 4. Manual transmission
The shift pattern is 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:2RZ- FE engine
