Idling for a long period with the air
conditioning on in stopandgo traffic.
Towing a trailer.
It is not a malfunction even if the needle
of the engine coolant temperature gauge
returns to “C” when the ignition switch is
turned to the “START” position.
NOTICE
 Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” on page 282 in
Section 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
It is not a malfunction even if the needle
of the tachometer returns to the bottom
position when the ignition switch is turned
to the “START” position.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

This meter displays the odometer and
two trip meters.
1. Odometer—Shows the total distance the vehicle has been driven.
2. Two trip meters—Show two different distances independently driven since
the last time each trip meter was set
to zero.
You can use one trip meter to calculate
the fuel economy and the other to
measure the distance on each trip. All
trip meter data is cancelled if the elec-
trical power source is disconnected.
3. Odometer/two trip meter changeover button—Switches the meter display.
To change the meter display, quickly
push and release the changeover but-
ton. The meter display changes in the
order from the odometer to trip meter
A to trip meter B, then back to the
odometer each time you push.
4. Trip meter reset button—Resets the two trip meters to zero.
To reset the trip meter A to zero, dis-
play the meter A reading, then push
and hold the button until the meter is
set to zero. The same process can be
applied for resetting the trip meter B.

(f) Malfunction Indicator Lamp
This lamp comes on when the ignition
key is turned to the “ON” position and
goes off after the engine starts. This
means that the warning light system is
operating properly.
If the lamp remains on, or the lamp
comes on while driving, first check the
followings.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after the
several trips, contact your Toyota dealer
as soon as possible.
If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, elec-
tronic throttle control system, automatic
transmission electrical system or warn-
ing light system itself. Contact your Toyota dealer as soon as
possible to service the vehicle.
If the engine speed does not increase with
the accelerator pedal depressed down,
there may be a problem somewhere in
your electronic throttle control system.
At this time, vibration may occur. Howev-
er, if you depress the accelerator pedal
more firmly and slowly, you can drive your
vehicle at low speeds. Have your vehicle
checked by your Toyota dealer as soon as
possible.
Even if the abnormality of the electronic
throttle control system is corrected during
low speed driving, the system may not be
recovered until the engine is stopped and
the ignition key is turned to “ACC” or
“LOCK” position.
CAUTION
Be especially careful to prevent erro-
neous pedal operation.
Emissions inspection and maintenance
(I/M) programs
Your vehicle may not pass a state
emission inspection if the malfunction
indicator lamp remains on. Contact your
Toyota dealer to check your vehicle’s
emission control system and OBD
(OnBoard Diagnostics) system before
taking your vehicle for the inspection.
For details, see “Emissions Inspection and
Maintenance (I/M) programs” on page 314
in Section 6.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(h) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light reminds you when to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.

“START”—Starter motor on. The key
will return to the “ON” position when
released.
For starting tips, see page 259 in Section
3.
It is not a malfunction even if the needle
of the tachometer, fuel gauge or engine
coolant temperature gauge returns to the
bottom position when the ignition switch is
turned to the “START” position. “ON”—Engine on and all accessories
on.
This is the normal driving position.
It is not a malfunction even if the needle
on the speedometer may move when the
ignition switch is turned to the “ON” posi-
tion.
“ACC”—Accessories such as the radio
operate, but the engine is off.
If you leave the key in the “ACC” or
“LOCK” position and open the driver’s
door, a buzzer will remind you to remove
the key.
“LOCK”—Engine is off and the steering
wheel is locked. The key can be re-
moved only at this position.
You must push in the key to turn it from
“ACC” to the “LOCK” position. The selec-
tor lever must be in the “P” position be-
fore pushing the key.
Once you remove the key, the engine im-
mobiliser system is automatically set. (See
“Engine immobiliser system” on page 12
in Section 12.)
When starting the engine, the key may
seem stuck at the “LOCK” position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
NOTICE
Do not leave the key in the “ON”
position if the engine is not running.
The battery will discharge and the
ignition could be damaged.

(b) Normal driving
1. Start the engine as instructed in “How to start the engine” on page 260 in
Section 3. The transmission must be in
“P” or “N”.
When the fourwheel drive control switch
knob is in “L4” (lowspeed position, center
differential locked), the driving pattern se-
lector setting has no effect on gear shift
timing. (See “Fourwheel drive system
(fulltime fourwheel drive models)” on
page 138 in this Section for information of
the fourwheel drive control.) 2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc. Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low or when the
fourwheel drive control switch knob is in
“L4” (lowspeed position, center differential
locked), the transmission will not shift into
the overdrive gear even in the “D” posi-
tion. (See “Fourwheel drive system (full
time fourwheel drive models)” on page
138 in this Section for information of the
fourwheel drive control.)
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.
If the automatic locking operation linked
with the shift position is set, all the side
doors and back door are automatically
locked when the shift lever is moved out
of the “P” position with the engine running
(including ignition switch in the “ON” posi-
tion) and all the side doors and back door
are closed. For details, see “—Automatic
door locking and unlocking functions” on
page 17 in Section 12. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
Shift into the “4” position. The trans-
mission will downshift to fourth gear
and engine braking will be enabled.
Shift into the “3” position. The trans-
mission will downshift to third gear
when the vehicle speed drops down to
or lower than the following speed, and
stronger engine braking will be en-
abled.

(b) Normal driving
1. Start the engine as instructed in “How to start the engine” on page 260 in
Section 3. The transmission must be in
“P” or “N”.
When the multimode control switch knob
is in “L4” (lowspeed position, fourwheel
drive, center differential locked), the driv-
ing pattern selector setting has no effect
on gear shift timing. (See “Fourwheel
drive system (multimode fourwheel drive
models)” on page 141 in this Section for
information of the multimode control.) 2. With your foot holding down the brake pedal, shift the selector lever to “D”.
When the lever is in the “D” position, the
automatic transmission system will select
the most suitable gear for running condi-
tions such as normal cruising, hill climb-
ing, hard towing, etc. Always use the “D” position for better fuel
economy and quieter driving. If the engine
coolant temperature is low or when the
multimode control switch knob is in “L4”
(lowspeed position, fourwheel drive,
center differential locked), the transmission
will not shift into the overdrive gear even
in the “D” position. (See “Fourwheel drive
system (multimode fourw
heel drive mod-
els)” on page 141 in this Section for in-
formation of the multimode control.)
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.
If the automatic locking operation linked
with the shift position is set, all the side
doors and back door are automatically
locked when the shift lever is moved out
of the “P” position with the engine running
(including ignition switch in the “ON” posi-
tion) and all the side doors and back door
are closed. For details, see “—Automatic
door locking and unlocking functions” on
page 17 in Section 12. (c) Using engine braking
To use engine braking, you can downshift
the transmission as follows:
