Vehicle status information and indicators
• When the outside temperature has
changed suddenly (at the entrance/exit of a garage, tunnel, etc.)
●When “--” is displayed, the system may be malfunctioning. Take your vehicle to any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■Fuel gauge and driving range dis-play
The fuel gauge and driving range dis- play are linked. If the fuel gauge and driving range display do not update after
refueling a small amount, they can be updated by performing the following pro-cedure:
1 Stop the vehicle on a level surface.
Wait until the fuel in the fuel tank stabi- lizes.
2 Press the display change button to change the odometer and trip meter
display to the odometer.
3 Turn the power switch off.
4 While pressing and holding the dis- play change button, turn the power switch to ON.
5 Continue holding the display change
button for approximately 5 seconds.
Release the button when the odometer begins blinking.
Updating will be complete when the odometer blinks for approximately 5 seconds and then returns to the normal
display.
■Liquid crystal display
 P. 1 0 6
■Customization
The gauges and meters can be custom-
ized in of the multi-information dis-
play. ( P.498)
■Changing the display
Press the display change button
until the desired item is displayed.
WARNING
■The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crys-tal information display. At extremely
low temperatures, the information dis- play 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
excessive engine braking and possi- bly an accident resulting in death or injury.
NOTICE
■To prevent damage to the engine and its components
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.481)

4-1. Before driving
Driving
■Sudden acceleration/steering
input/cornering
Executing sharp turns when towing
may result in the trailer colliding
with your vehicle. Decelerate well in
advance when approaching turns
and take them slowly and carefully
to avoid sudden braking.
■Important points regarding
turning
The wheels of the trailer 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 and charging system perfor-
mance when using engine braking,
do not use the transmission in D.
( P.197)
■If the engine overheats
Towing a loaded trailer up a long,
steep incline in temperatures
exceeding 30°C (85°F) may result
in the engine overheating. If the
engine coolant temperature gauge
indicates that the engine is over-
heating, turn the air conditioning off
immediately, leave the road and
stop the vehicle in a safe place.
( P.481)
■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.
WARNING
F o l l o w a l l t h e i n s t r u c t i o n s d e s c r i b e d i n this section. Failure to do so could
cause an accident resulting in death or serious injury.
■Trailer towing precautions
When towing, make sure that none of the weight limits are exceeded.
( P.183)
■Vehicle speed in towing
Observe the legal maximum speeds for trailer towing.

■When the downhill assist control
system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill
assist control system will stop operating, a buzzer will sound and the downhill assist control system indicator will start
flashing, and “Traction Control Turned OFF” will be shown on the multi-infor-mation display. Refrain from using the
system until the downhill assist control system indicator stays on and “Traction Control Turned OFF” the message goes
off. (The vehicle can be driven normally during this time.)
■Sounds and vibrations caused by the downhill assist control system
●A sound may be heard from the engine compartment when the hybrid
system is started or just after the vehi- cle begins to move. This sound does not indicate that a malfunction has
occurred in downhill assist control system.
●Either of the following conditions may occur when the downhill assist control system is operating. None of these
are indicators that a malfunction has occurred.• Vibrations may be felt through the
vehicle body and steering. • A motor sound may be heard after the vehicle comes to a stop.
■System malfunction
In the following cases, have your vehicle checked by any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
●The downhill assist control system
indicator does not come on when the power switch is turned to ON.
●The downhill assist control system indicator does not come on when the “DAC” switch is pressed.
●The slip indicator light comes on.
WARNING
■The system may not operate on the following surfaces, which
may lead to an accident causing death or serious injury
●Slippery surfaces such as wet or
muddy roads
●Icy surface
●Unpaved roads
