Vehicles with cruise controlÐWhen 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 de-
crease the vehicle speed, see Cruise controlº in this chapter.
Automatic transmission (electronically controlled typeÐtwo-wheel drive models)

58Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the selector le- ver pulled toward you).
(a) Normal driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal 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.
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
!
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 O/D
OFFº indicator light will come on and the transmission will downshift to the
third gear.
Shift into the 2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the maximum al-
lowable speed for second gear, andmore powerful engine braking will beobtained.
Shift into the Lº position. The trans- mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the maximum allowable
speed for Lº position and maximum
engine braking will be applied.
Vehicles with cruise controlÐWhen 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 controlº in this
chapter.
MAXIMUM ALLOWABLE SPEEDS
2º 136 km/h (85 mph) . . . . . . . . . . . .
Lº 74 km/h (46 mph) . . . . . . . . . . . . .
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid. CAUTION
!
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to
keep engine rpm from going into
the red zone. The maximum allow-able speed (approximate) for each
position is given above for yourreference.
Do not continue hill climbing for along time in the 2º or Lº posi-
tion. This may cause severe auto-matic transmission damage from
overheating. To prevent such damage, use Dº position for hillclimbing or hard towing.
(c) 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 Rº
position.
NOTICE
Never shift into reverse while the vehicle is moving.

59
(d) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever fully to se- curely apply the parking brake.
3. With the brake pedal pressed down,
shift the selector lever to the Pº position.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circum-
stances. Serious mechanical dam-
age and loss of vehicle control mayresult.
CAUTION
!
(e) 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 notuse overdrive.
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping. CAUTION
!
NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal.
It can cause the transmission tooverheat. Always use the brake pedal or parking brake.
(f) Driving in POWERº mode In the POWERº mode, the transmission
is shifted up and down at a higher vehicle
speed than in the NORMALº mode and a
more powerful acceleration is achieved.
To set the POWERº mode, push in the
driving pattern selector button. The
POWERº mode indicator light comes on.
For ordinary driving, Toyota recommends
using the NORMALº mode to improve
fuel economy.
(g) If you cannot shift the selector lever
out of Pº position
If you cannot shift the selector lever from the Pº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see If you cannot shift automatic transmission selector leverº in Part 4.

Vehicles with cruise controlÐWhen 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 controlº in this chapter.
Automatic transmission (electronically controlled typeÐfour-wheel drive models)

61
Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
When the front drive control lever is in L4º
(low-speed position, four-wheel drive),
the driving pattern selector setting has no
effect on gear shift timing. (See Four-
wheel drive systemº in this Chapter for in-
formation of the front drive control lever.)
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal 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 L4º
(low-speed position, four-wheel drive),
the transmission will not shift into the
overdrive gear even with the overdrive
switch on. (See Four-wheel drive sys-
temº in this Chapter for information of the
front drive control lever.)
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
!
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 O/D
OFFº indicator light will come on andthe transmission will downshift to the
third gear.
Shift into the 2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the maximum
allowable speed for second gear, and more powerful engine braking will be obtained.
Shift into the Lº position. The trans- mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the maximum allowable
speed for Lº position and maximum
engine braking will be applied.
Vehicles with cruise controlÐWhen 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 controlº in this
chapter.

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 gradeÐuse 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 follow-
ing speeds: 2RZ-FE engine Low altitude Ð1219 m (4000 ft) or lower
gear km/h (mph)

Downshift to the appropriate gear if accel-
eration is needed when you are cruising
below the above downshifting 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 exces-
sive engine wear and high fuel consumption.

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.
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid. CAUTION
!
NOTICE
Make sure the vehicle is completely stopped before shifting into
reverse.
Use the front drive control lever to se-
lect the following transfer modes. H2º (high speed position, two-wheel
drive): Lever at H2º

To engage the free-wheeling hubs,
turn the hubs to LOCKº. To disen-
gage, turn the hubs to FREEº Make sure the triangle mark on the hub
aligns with the other one at the side you
wish to set.
Setting the free-wheeling hubs in FREEº
allows you to disengage the front axle and
driveshaft so that they are not revolving.
This reduces noise and wear when the ve-
hicle is in two-wheel drive.
You should drive with the hubs in LOCKº for at least 16 km (10 miles) each month.
This will assure that the front drive compo-
nents are lubricated.Steel wheels
Aluminum wheels The A.D.D. can be engaged or disen-
gaged by the shifting operations
described in (d) Shifting procedureº.
You should drive in four-wheel drive for at least 16 km (10 miles) each month. This
