When the tail lights are on, the brightness of the instrument panel
lights can be adjusted. (On vehicles with an automatic light control
system, the instrument panel lights can be adjusted when the sur-
rounding area is dark and the tail lights are on.)
The brightness of the clock light can be adjusted regardless of
whether the tail lights are on or off.

■The meters and display illuminate when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
■When disconnecting and reconnecting battery terminals
The following information data will be reset:
●Average fuel consumption
●Driving range
●Average vehicle speed
CAUTION
■The display at low temperatures
Allow the interior of the vehicle to warm up before using the display. At
extremely low temperatures, the 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 down-
shift again, causing rapid and excessive engine braking and possibly an
accident resulting in death or injury.
■Cautions during setting up the display
As the engine needs to be running during setting up the display, ensure that
the vehicle is parked in a place with adequate ventilation. In a closed area
such as a garage, exhaust gases including harmful carbon monoxide (CO)
may collect and enter the vehicle. This may lead to death or a serious
health hazard.
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 maximum engine speed.
●The engine may be overheating if the high engine coolant temperature
warning light comes on. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (P. 537)

CAUTION
■When working near the electric cooling fan or radiator grille
Vehicles without a smart key system: Be sure the engine switch is off. With
the engine switch in the “ON” position, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 442)
Vehicles with a smart key system: Be sure the engine switch is off. With the
engine switch in IGNITION ON mode, the electric cooling fan may automat-
ically start to run if the air conditioning is on and/or the coolant temperature
is high. (P. 442)
■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.

The coolant level is satisfactory if it is between the “F” and “L” lines on
the reservoir when the engine is cold.
Reservoir cap
“F” line
“L” line
If the level is on or below the “L”
line, add coolant up to the “F” line.
(P. 537)
■Coolant selection
Only use “Toyota Super Long Life Coolant” or a similar high quality ethylene
glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with
long-life hybrid organic acid technology.
For the U.S.A.: “Toyota Super Long Life Coolant” is a mixture of 50% cool-
ant and 50% deionized water. (Minimum temperature: -31F
[-35C])
For Canada: “Toyota Super Long Life Coolant” is a mixture of 55% cool-
ant and 45% deionized water. (Minimum temperature: -44F
[-42C])
For more details about engine coolant, contact your Toyota dealer.
■If the coolant level drops within a short time of replenishing
Visually check the radiator, hoses, engine coolant reservoir caps, drain cock
and water pump.
If you cannot find a leak, have your Toyota dealer test the cap and check for
leaks in the cooling system.

ture gauge needle continually points higher than normal.
●Changes in exhaust sound
●Excessive tire squeal when cornering
●Strange noises related to the suspension system
●Pinging or other noises related to the engine
