Vehicle status information and indicators
■Outside temperature display
●In the following situations, the cor-
rect outside temperature may not
be displayed, or the display may
take longer than normal to
change:
• When stopped, or driving at low
speeds (less than 16 mph [25
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
 P. 8 3
■Changing the display
Press the display change button
until the desired item is dis-
played.
■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
WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before using the liquid
crystal information 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.

Driving
4-6.Driving tips
 Use fluids that are appropriate
to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
Have a service technician
inspect the condition of the
battery.
 Have the vehicle fitted with
four snow tires or purchase a
set of tire chains for the front
tires.
Ensure that all tires are the same
size and brand, and that chains
match the size of the tires.
Winter driving tips
Carry out the necessary
preparations and inspec-
tions before driving the
vehicle in winter. Always
drive the vehicle in a man-
ner appropriate to the pre-
vailing weather conditions.
Pre-winter preparations
WARNING
■Driving with snow tires
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in a
loss of vehicle control and cause
death or serious injury.
●Use tires of the size specified.
●Maintain the recommended
level of air pressure.
●Do not drive in excess of 75
mph (120 km/h), regardless of
the type of snow tires being
used.
●Use snow tires on all, not just
some wheels.
■Driving with tire chains
Observe the following precautions
to reduce the risk of accidents.
Failure to do so may result in the
vehicle being unable to be driven
safely, and may cause death or
serious injury.
●Do not drive in excess of the
speed limit specified for the tire
chains being used, or 30 mph
(50 km/h), whichever is lower.
●Avoid driving on bumpy road
surfaces or over potholes.
●Avoid sudden acceleration,
abrupt steering, sudden brak-
ing and shifting operations that
cause sudden engine braking.
●Slow down sufficiently before
entering a curve to ensure that
vehicle control is maintained.
●Do not use LTA (Lane Tracing
Assist) system. (if equipped)
●Do not use LDA (Lane Depar-
ture Alert with steering control)
system. (if equipped)
NOTICE
■Repairing or replacing snow
tires
Request repairs or replacement of
snow tires from Toyota dealers or
legitimate tire retailers.
This is because the removal and
attachment of snow tires affects
the operation of the tire pressure
warning valves and transmitters.

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.
●Be careful not to touch the
engine, radiator, exhaust mani-
fold, etc. right after 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.
Fuel fumes are flammable.
ItemsParts and tools●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 fan may automati-
cally start to run if the air condi-
tioning is on and/or the coolant
temperature is high. ( P.438)
■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.
