■Eco-friendly driving
■ The meters and display illuminate when
The engine switch is in IGNITION ON mode.
■ The brightness of the in strument panel lights
● When the headlight switch is turned to on, the brightness will be reduced
slightly unless the control knob is turned fully clockwise.
● When the knob is turned fully clockwise, the display audio/navigation sys-
tem screen will always be in day mode regardless of the headlight switch
position.
■ Customization
The instrument panel light auto dimmer control can be changed.
(Customizable feature: →P. 449)
During Eco-friendly acceleration (Eco
driving), Eco Driving Indicator Light will
turn on. If the acceleration exceeds the
Eco driving accelerator upper limit, or the
vehicle is stopped, the light turns off.
Eco Driving Indicator Light will not operate
in the following conditions:
●
The shift lever is in anything other than
D.
● The paddle shift switch is used.
● The vehicle is in sport mode.
● The vehicle speed is approximately 80
mph (130 km/h) or higher.
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 engine coolant temperature 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. (→ P. 418)

2665-1. Using the air conditioning system and defogger
■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning system is controlled as follows to pri-
oritize fuel efficiency:
● When the outside temperature exceeds 68°F (20°C), the air conditioning
system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● It is possible to switch to outside air mode at any time by pressing
.
■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting and
the ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow
immediately after is touched.
■ Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the wind-
shield effectively.
● If you turn off, the windows may fog up more easily.
● The windows may fog up if the recirculated air mode is used.
■ Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode to the recirculated air mode. This is effective in
preventing outside air from entering the vehicle interior. During cooling oper-
ation, setting the recirculated air mode will also cool the vehicle interior
effectively.
● Outside/recirculated air mode may automatically switch depending on the
temperature setting, outside temperature, pressure, engine coolant tem-
perature or inside temperature.
■ When the outside temperature exceeds 75°F (24°C) and the air condition-
ing system is on (U.S.A. only)
● In order to reduce the air conditioning power consumption, the air condition-
ing system may switch to recirculated air mode automatically. This may also
reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the engine switch
is turned to IGNITION ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■When the outside temperat ure falls to nearly 32°F (0°C)
The dehumidification function may not operate even when is touched.

3346-3. Do-it-yourself maintenance
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. 418)
■ 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.
U.S.A.:
“Toyota Super Long Life Coolant” is a mixture of 50% coolant and 50% deion-
ized water. (Minimum temperature: -31 °F [-35 °C])
Canada:
“Toyota Super Long Life Coolant” is a mixture of 55% coolant and 45% deion-
ized 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.

3867-2. Steps to take in an emergency
●Fluid leaks under the vehicle.
(Water dripping from the air co nditioning after use is normal.)
● Flat-looking tires or uneven tire wear
● Engine coolant temperature 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
● Engine missing, stumbling or running roughly
● Appreciable loss of power
● Vehicle pulls heavily to one side when braking
● Vehicle pulls heavily to one side when driving on a level road
● Loss of brake effectiveness, spon gy feeling, pedal almost touches
the floor
If you think something is wrong
If you notice any of the follow ing symptoms, your vehicle proba-
bly needs adjustment or repair. Contact your Toyota dealer as
soon as possible.

4187-2. Steps to take in an emergency
●The needle of the engine coolant temperature gauge ( →P. 7 9 )
enters the red zone or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● “Engine Coolant Temp is High” is shown on the multi-information
display.
● Steam comes out from under the hood.
Stop the vehicle in a safe place and turn off the air conditioning sys-
tem, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficient ly, inspect the
hoses and radiator core (radia-
tor) for any leaks.

Cooling fan
If a large amount of coolant
leaks, immediately contact your
Toyota dealer.
The coolant level is satisfactory
if it is between the “F” and “L”
lines on the reservoir.Reservoir

When trouble arises
Add engine coolant if neces-
sary.
Water can be used in an emer-
gency if engine coolant is unavail-
able.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans oper ate and to check for coolant leaks
from the radiator or hoses.
The fans operate when the air conditioning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking the
fan sound and air flow. If it is difficult to check these, turn the air condition-
ing system on and off repeatedly. (The fans may not operate in freezing
temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Toyota dealer.
If the fans are operating:
Have the vehicle in spected at the nearest Toyota dealer.
