The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
Nearly fullÐNeedle at ºFº
Nearly emptyÐNeedle at ºEº
It is a good idea to keep the tank over
1/4 full.
This fuel gauge has a non-return type
needle which remains at the last indicated
position when the ignition switch is turned
off.
If the fuel level approaches ºEº or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate or the low fuel level
warning light may come on earlier than
usual.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately.
The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.

With tachometer
Without tachometer The gauge indicates the engine coolant
temperature when the ignition switch is
on. The engine operating temperature
will vary with changes in weather and
engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:
Driving up a long hill on a hot day.
Reducing speed or stopping after high
speed driving.
Idling for a long period with the air
conditioning on in stop-and-go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as thismay cause the engine to overheat.The thermostat is designed to con-
trol the flow of coolant to keep thetemperature of the engine withinthe specified operating range.
Do not continue driving with an overheated engine. See ºIf your ve-hicle overheatsº in Part 4.

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 when the
vehicle speed drops down to or lower
than 106 km/h (66 mph). The transmis-
sion will downshift to the second gear
and more powerful engine braking will
be obtained.
Shift into the ºLº position when the
vehicle speed drops down to or lower
than 61 km/h (38 mph). The transmis-
sion will downshift to the first gear 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.

In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission) or overdrive (automatic
transmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over 305C [85 5F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to ºIf
your vehicle overheatsº in Part 4 of
this manual.
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in ºPº (automatic)
or in first or reverse (manual). Avoid
parking on a slope with a trailer, but
if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un- der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load. 4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or
ºPº (automatic) and turn off the engine.
When restarting out after parking on a
slope:
1. With the transmission in ºPº position (automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de-
pressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmission ve-
hicles) and slowly pull or back away
from the wheel blo cks. Stop and apply
your brakes.
4. Have someone retrieve the blo cks.
CAUTION
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle-
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.
