5-1. Before driving
Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. D ecelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the tr ailer will travel
closer to the inside of the curve
than the wheels of the vehicle. To
make allowance for this, take the
turns wider than you would nor -
mally do.
■Important points regarding
stability
Vehicle movement resulting from
uneven road surfaces and strong
crosswinds will affect handling. The
vehicle may also be rocked by
passing buses or large trucks. Fre -
quently check behind when moving
alongside such vehicles. As soon
as such vehicle movement occurs,
immediately start to decelerate
smoothly by slowly applying the
brakes. Always steer the vehicle
straight ahead while braking.
■Passing other vehicles
Consider the total combined length
of your vehicle and trailer and
ensure that the vehicle-to-vehicle
distance is sufficient before execut -
ing lane changes.
■Transmission information
To maintain engine braking effi -
ciency, when using engine braking,
do not use the transmission in D.
( →P.321)
■If the hybrid system overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the hybrid system overheating. If
the high coolant temperature warn -
ing light indicates that the hybrid
system is overheating, turn the air
conditioning off immediately, leave
the road and stop the vehicle in a
safe place. ( →P.611)
■When parking the vehicle
Always place wheel chocks under
the wheels of both the vehicle and
trailer. Firmly set the parking brake
and shift the shift lever to P.
■Break-in schedule
Toyota recommends that vehicles fitted
with new power train components
should not be used for towing trailers for the first 800 km (500 miles).
■Maintenance
●Maintenance must be performed more frequently when using the vehicle for
towing due to the greater weight bur -
den placed on the vehicle compared to normal driving.
●Retighten all bolts securing the hitch - ing ball and bracket after towing for
approximately 1000 km (600 miles).
■If trailer sway occurs
One or more factor s (crosswinds, pass- ing vehicles, rough roads, etc.) can
adversely affect handling of your vehicle
and trailer, causing instability.

3185-2. Driving procedures
■When the ambient temperature is
low, such as during winter driving conditions
●When starting the hy brid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is

■Heating
●In HV mode, the gasoline engine may
operate in order to extract heat from the engine coolant via the heater.
●In EV mode, heating is done by a heat pump system.
• When the outside t emperature is low
or it is snowing, compared to conven - tional vehicles, heating may be less
effective and warm air may not come
out. • When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte- rior. However, it is not a malfunction.
In this situat ion, the air temperature
from the outlets may not change even though the set tem perature is raised.
• If frost has formed of the outside heat
exchanger, the heating performance will decline. The frost can be removed
from the outside heat exchanger by
operating the Remote Air Conditioning System before driving ( →P.460).
When frosted over, the heating opera -
tion of the Remote Air Conditioning System starts after defrosting.
• When “AUTO” switch is turned on, the
heating is controlle d optimally. There- fore, the set heating performance may
not be achieved even if the fan speed
setting is increased.
Outside heat exchanger
●In the following situations the gasoline
engine may operate in order to extract heat from the engine coolant via the
heater even in EV mode.
• The outside temperature is approxi -
mately -10°C (14°F) or low

■Fogging up of the windows
●The windows will ea sily fog up when
the humidity in the vehicle is high.
Turning “A/C” s witch on will dehumid- ify the air from the outlets and defog
the windshield effectively.
●If you turn “A/C” switch off, the win -
dows may fog up more easily.
●The windows may fog up if the recir -
culated air mode is used.
■While using “My Room Mode”
●It may not be possible to obtain the
intended defogging performance even
if is pressed. If the windows
need to be defogged before driving,
stop charging powe r and then press
.
●When the outside te mperature is low,
heating may feel insufficient due to
restricted operation of the air condi -
tioning. Heating cannot be performed when it is -10°C (14° F) or less as the
gasoline engine cannot be started
during “My Room Mode”. If heating is desired, stop charging and remove
the AC charging cable from the vehi -
cle.
■When driving o n dusty roads
Close all windows. If dust thrown up by
the vehicle is still d rawn into the vehicle
after closing the windows, it is recom - mended that the air intake mode be set
to outside air mode and the fan speed to
any setting except off.
■Outside/recirculated air mode
●Setting to the recir culated air mode
temporarily is recommended in pre - venting dirty air from entering the
vehicle interior and helping to cool the
vehicle when the ou tside air tempera- ture is high.
●Outside/recirculated air mode may automatically switch depending on the
temperature setting or the inside tem-
perature.
■Operation of the air conditioning system in Eco drive mode
●In Eco drive mode, the air conditioning system is controlled as follows to pri -
oritize fuel efficiency:
• Engine speed and compressor opera - tion controlled to res trict heating/cool-
ing capacity
• Fan speed restrict ed when automatic mode is selected
●To improve air conditioning perfor - mance, perform the following opera -
tions:
• Turn off Eco drive mode ( →P.434) • Turn off blower customization
( →P.454)
■When the outside temperature falls
to nearly 0°C (32°F)

low
●When the hybrid syst em is cool (for
example, after being left for a long time in low temperatures)
■Windshield defogger
When defogging the windshield using
the Remote Air Conditioning System, defogging may be insufficient due to the
power being restricted more than during
normal air conditioning operation. Also, the outside of the windshield may fog up
due to the outside temperature, humidity
or air conditioning set temperature.
■Using the heater via the Remote Air Conditioning System
●When the outside te mperature is low, heating may feel insufficient due to
restricted operation of the air condi -
tioning.
●When the outside heat exchanger
becomes frosted ov er, heating perfor- mance may decline due to automati -
cally switchi ng to the frost removal
operation. ( →P.452)
