156 2-1. Driving procedures
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO), which is colorless
and odorless. Inhaling exhaust gases may lead to death or a serious health
hazard.
●If the vehicle is in a poorly ventilated area, stop the hybrid system. In a
closed area, such as a garage, exhaust gases may collect and enter the
vehicle. This may lead to death or a serious health hazard.
● The exhaust system should be checked occasionally. If there is a hole or
crack caused by corrosion, damage to a joint or abnormal exhaust noise,
be sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the hybrid system off. Otherwise, if you accidentally move the
shift lever or depress the accelerator pedal, this could cause an accident or
fire due to hybrid system overheating. Additionally, if the vehicle is parked in
a poorly ventilated area, exhaust gases may collect and enter the vehicle,
leading to death or a serious health hazard.

The brightness of the instrument panel lights
When the tail lights are turned on, the meter’s brightness will be reduced
slightly unless the meter brightness level adjustment is set to the brightest
setting.
If the tail lights are turned on when the surroundings are dark, the meter’s
brightness will reduce slightly. However, when the surroundings are bright,
such as during the daytime, the meter’s brightness will not be reduced even
if the tail lights are turned on.
■ Fuel gauge and odometer/trip meter display remain on mode
After the “POWER” switch has been turned off, the fuel gauge and odome-
ter/trip meter display remain on for 10 minutes, enabling the fuel gauge and
odometer/trip meter values to be checked again without having to turn the
“POWER” switch to ON mode.
When confirming the gauges and meters, turn the headlight switch to the
position. Press the display change button to change between the
odometer and trip meter displays.
NOTICE
■ To prevent damage to the engine and its components
The engine may be overheating if the rightmost segment of the engine cool-
ant temperature display is flashing. In this case, immediately stop the vehicle
in a safe place, and check the engine after it has cooled completely.

When driving
■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur,
refrain from excessive steering input or stop the vehicle and turn the hybrid
system off. The EPS system should return to normal within 10 minutes.
■ If the slip indicator comes on...
It may indicate a malfunction in the TRAC, VSC and ABS. Contact your
Toyota dealer.
CAUTION
■ABS does not operate effectively when
●Tires with inadequate gripping ability are used (such as excessively worn
tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or roads with uneven surfaces

Interior features
■Operation of the air conditio ning system in Eco drive mode
In Eco drive mode, the air conditioning sy stem is controlled as follows to pri-
oritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode
■ Customization
The air conditioning control of Eco drive mode can be changed to the same
setting as that used in normal drive mode.
(Customizable features P. 498)
■ 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 pressed.
■ 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
windshield 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
outside/recirculated air mode button to the recirculated air mode. This is
effective in preventing outside air from entering the vehicle interior. Dur-
ing cooling operation, setting the recirculated air mode will also cool the
vehicle interior effectively.
● Outside/recirculated air mode may automatically switch depending on
the temperature setting or the inside temperature.
