■The meters and display illumi-
nate when
The engine switch is in ON.
■Outside temperature display
●In the following si tuations, the cor-
rect outside tempe rature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low
speeds (less than 12 mph [20
km/h])
• When the outside temperature
has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
■Liquid crystal display
Small spots or light spots may
appear on the display. This phenom-
enon is characteristi c of liquid crys-
tal displays, and there is no problem
continuing to use the display.
■Customization
The meters can be customized on of the multi-information display.
(  P.94)
■Display items
 Odometer
Displays the total distance the vehi-
cle has been driven.
 Trip meter A/trip meter B
Displays the distance the vehicle
has been driven since the meter
was last reset. Trip meters A and B
can be used to record and display
different distances independently.
Distance until next engine oil
change
Displays the distance the vehicle
can be driven until an oil change is
WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before u sing the liquid
crystal informat ion display. At
extremely low temperatures, the
information display monitor may
respond slowly, and display
changes may be delayed.
For example, there is a lag
between the driver’s shifting and
the new gear number appearing
on the display. This lag could
cause the driver to downshift
again, causing rapid and exces-
sive engine braking and possibly
an accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
●Do not let the indicator needle
of the tachometer enter the red
zone, which indicates the maxi-
mum engine speed.
●The engine may be overheating
if the engine coolant tempera-
ture gauge is in the red zone
(H). In this case, immediately
stop the vehicle in a safe place,
and check the engine after it
has cooled completely.

or steep grade. If the engine
coolant temperature gauge
indicates overheating, imme-
diately turn off the air condi-
tioning (if in use), pull your
vehicle off the road and stop
in a safe spot. (P.469)
 Always place wheel blocks
under both the vehicle’s and
the trailer’s wheels when
parking. Put the transmission
in P and apply the parking
brake. Avoid parking on a
slope, but if unavoidable, do
so only after performing the
following:
1 Apply the brakes and keep
them applied.
2 Have someone place wheel
blocks under both the vehi-
cle’s and trailer’s wheels.
3 When the wheel blocks are in
place, release the brakes
slowly until the blocks absorb
the load.
4 Shift into P and apply the
parking brake.
5 Turn off the engine.
 When restarting after parking
on a slope:
1 With the transmission in P,
start the engine. Be sure to
keep the brake pedal
depressed.
2 Shift into a forward gear. If
reversing, shift into R. 3
If the parking brake is in man-
ual mode, release the park-
ing brake. ( P.205)
4 Release the brake pedal, and
slowly pull or back away from
the wheel blocks. Stop and
apply the brakes.
5 Have someone retrieve the
blocks.

To enter M mode, shift the shift
lever to M. Gears can then be
selected by operating the shift
lever, allowing you to drive in the
gear of your choosing. 1
Upshifting
2 Downshifting
The gear changes once every time
the shift lever is operated.
The selected gear, from M1 to M8,
will be fixed and displayed on the
meters.
When in the M position, the gear
will not change unless the shift
lever is operated.
However, even when in the M
position, the gears will be auto-
matically changed in the follow-
ing situation:
 When vehicle speed drops
(downshift only).
 When the automatic transmis-
sion fluid or engine coolant
temperature is low.
 When automatic transmis-
sion fluid temperature is high
(upshift only).
 When the needle of the
tachometer is in the red zone
(the range which exceeds the
allowable revs of the engine).
In the following situation, the
gear will not shift even if the shift
lever is operated.
 The vehicle speed is low
(upshift only).
■Downshifting restriction warn-
ing buzzer
To help ensure safety and driving
performance, dow nshifting opera-
tion may sometimes be restricted.
(A buzzer will sound twice.)
WARNING
■To prevent an accident when
releasing the shift lock
Before pressing the shift lock
override button, make sure to set
the parking brake and depress the
brake pedal.
If the accelerator pedal is acci-
dentally depressed instead of the
brake pedal when the shift lock
override button is pressed and the
shift lever is shifted out of P, the
vehicle may suddenly start, possi-
bly leading to an accident result-
ing in death or serious injury.

WARNING
The engine compartment contains
many mechanisms and fluids that
may move suddenly, become hot,
or become electrically energized.
To avoid death or serious injury,
observe the following precautions.
■When working on the engine
compartment
●Keep hands, clothing and tools
away from the moving fan and
engine drive belt.
ItemsParts and tools●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right a fter driving as
they may be hot. Oil and other
fluids may also be hot.
●Do not leave anything that may
burn easily, such as paper and
rags, in the engine compart-
ment.
●Do not smoke, cause sparks or
expose an open flame to fuel or
the battery. Fuel and battery
fumes are flammable.
●Be extremely cautious when
working on the battery. It con-
tains poisonous and corrosive
sulfuric acid.
■When working near the elec-
tric cooling fan or radiator
grille
Be sure the engine switch is off.
With the engine switch in ON, the
electric cooling fa n may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.390)
■Safety glasses
Wear safety glasses to prevent
flying or falling material, fluid
spray, etc. from getting in your
eyes.
NOTICE
■If you remove the air cleaner
filter
Driving with the air cleaner filter
removed may cause excessive
engine wear due to dirt in the air.
