Eco savings
●Fuel cost and savings should be used as a guide only.
● Depending on refueling methods, driving conditions and environmental fac-
tors, the actual and displayed fuel costs may differ.
● In some cases, fuel cost and savings may not be linked to the eco score
evaluation.
■ When disconnecting and reconnect ing 12-volt battery terminals
The following information data will be reset:
● Clock
● Past record (aside from the top 3 results)
● Average fuel consumption
● Cruising range
● Average vehicle speed
● Driving time
● EV driving rate/EV driven distance
Additionally, some displays may return to their default settings.
■ Liquid crystal display
Small spots or light spots may appear on the display. This phenomenon is
characteristic of liquid crystal displays, and there is no problem continuing to
use the display.
WARNING
■Eco score
Eco score should be used as a guide only. Always drive safely in accor-
dance with road and traffic conditions.
■ The information display at low temperatures
Allow the interior of the vehicle to warm up before using the liquid crystal
information 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 l ag 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 hybrid system 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.

Alarms and warning indicators
A combination of exterior and interior alarms as well as warning messages
shown on the multi-information display is used to prevent theft of the vehicle
and accidents resulting from erroneous operation. Take appropriate mea-
sures in response to any warning message on the multi-information display.
(→P. 487)
The following table describes circumstances and correction procedures when
only alarms are sounded.
■ Battery-saving function
The battery-saving function will be activated in order to prevent the electronic
key battery and the 12-volt battery from being discharged while the vehicle is
not in operation for a long time.
●In the following situations, the smart key system may take some time to
unlock the doors.
• The electronic key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The smart key system has not been used for 5 days or longer.
● If the smart key system has not been used for 14 days or longer, the doors
cannot be unlocked at any of the doors except the driver’s door. In this case,
take hold of the driver’s door handle, or use the wireless remote control or
the mechanical key, to unlock the doors.
■ Electronic key battery-saving function
When battery-saving mode is set, battery depletion is minimized by stopping
the electronic key from receiving radio waves.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving on slippery road surfaces
● Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle.
● Sudden acceleration, engine braking due to shift changing, or changes in
engine speed could cause the vehicle to skid.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected.
■ When shifting the shift lever
● Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may result in an accident or damage to the vehicle.
● Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Do not shift the shift lever to a driving position while the vehicle is moving
backward.
Doing so can damage the transmission and may result in a loss of vehicle
control.
● Shifting the shift lever to N while the vehicle is moving will disengage the
hybrid system. Engine braking is not available when N is selected.
● Be careful not to shift the shift lever with the accelerator pedal depressed.
Shifting the shift lever to any position other than P or N may lead to unex-
pected rapid acceleration of the vehicle that may cause an accident and
result in death or serious injury.
■ If you hear a squealing or scrapi ng noise (brake pad wear limit indica-
tors)
Have the brake pads checked and replaced by your Toyota dealer as soon
as possible.
Rotor damage may result if the pads are not replaced when needed.
It is dangerous to drive the vehicle when the wear limits of the brake pads
and/or those of the brake discs are exceeded.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Do not leave glasses, cigarette lighters, spray cans, or soft drink cans in
the vehicle when it is in the sun.
Doing so may result in the following:
• Gas may leak from a cigarette lighter or spray can, and may lead to a
fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to deform or crack.
• Soft drink cans may fracture, causing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle's
electrical components.
● Do not leave cigarette lighters in the vehicle. If a cigarette lighter is in a
place such as the glove box or on the floor, it may be lit accidentally when
luggage is loaded or the seat is adjusted, causing a fire.
● Do not attach adhesive discs to the windshield or windows. Do not place
containers such as air fresheners on the instrument panel or dashboard.
Adhesive discs or containers may act as lenses, causing a fire in the vehi-
cle.
● Do not leave a door or window open if the curved glass is coated with a
metallized film such as a silver-colored one. Reflected sunlight may cause
the glass to act as a lens, causing a fire.
● Always apply the parking brake, shift the shift lever to P, stop the hybrid
system and lock the vehicle.
Do not leave the vehicle unattended while the “READY” indicator is illumi-
nated.
Sound or shuddering may not be noticed even when the hybrid vehicle is
ready to drive (when the “READY ” indicator is illuminated).
If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
● Do not touch the exhaust pipes while the “READY” indicator is illuminated
or immediately after turning the hybrid system off.
Doing so may cause burns.
