■ Remaining hybrid battery (traction battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or electricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may
not reach the highest level (level 8). However, this does not indicate a mal-
function.

Resetting the consumption data
Display Audio system
Selecting “Clear” on the “Consumption” screen will reset the fuel consump-
tion and the regenerated energy for the past 30 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.
Navigation system
Selecting “Clear” on the “Consumption” screen will reset the fuel consump-
tion and the regenerated energy for the past 30 minutes.
Selecting “Yes” on the following screen will confirm resetting of all the data.
Multi-information display
If the “POWER” switch is turned OFF, average fuel consumption and regen-
erated energy data will be reset.
■ Resetting the monthly fuel consumption/eco savings record
Press and hold the “TRIP” button while the monthly fuel consumption/eco
savings record is displayed.
A confirmation message will be displayed.
Press and hold the “TRIP” button to reset the data.
Press the “DISP” button to cancel the reset operation. The screen will return
to the previous display if no buttons are pressed for approximately 10 sec-
onds.
■ Cruising range
Displays the estimated maximum distance that can be driven with the quan-
tity of fuel remaining.
This distance is computed based on your average fuel consumption.
As a result, the actual distance that can be driven may differ from that dis-
played.
■ Odometer/trip meter/distance to empty
The odometer/trip meter/distance to empty will not be displayed while the
monthly fuel consumption record or the eco savings record is being dis-
played.

Hybrid vehicle driving tips
For economical and ecological driving, pay attention to the
following points:
■Using Eco drive mode
When using Eco drive mode, the torque corresponding to the
accelerator pedal depression amount can be generated more
smoothly than it is in normal conditions. In addition, the opera-
tion of the air conditioning system (heating/cooling) will be mini-
mized, improving th e fuel economy. (P. 204)
■ Use of Hybrid System Indicator
Eco-friendly driving is possible by keeping the indicate of Hybrid
System Indicator within Eco area. ( P. 225)
■ When braking the vehicle
Make sure to operate the brakes gently and in good time. A
greater amount of electrical energy can be retained when slow-
ing down.
■ Delays
Repeated acceleration and deceleration, as well as long waits at
traffic lights, will lead to bad fuel consumption. Check traffic
reports before leaving and avoid delays as much as possible.
When encountering a delay, gently release the brake pedal to
allow the vehicle to move forward slightly while avoiding overuse
of the accelerator pedal. Doing so can help control excessive
gasoline consumption.
■ Highway driving
Control your speed and keep at a constant speed. Also, before
stopping at a toll booth or similar, allow plenty of time to release
the accelerator and gently apply the brakes. A greater amount of
electrical energy can be reta ined when slowing down.

■
Air conditioning on/off
Switch the air conditioning ( ) to off when it is not needed.
Doing so can help control excessive gasoline consumption.
In summer: In high temperatures, use the recirculated air mode.
Doing so will help to reduce t he burden on the air conditioner
and reduce fuel consumption as well.
In winter: Because the gasoline engine will not automatically cut
out until the gasoline engine and the interior of the vehicle are
warm, it will consume fuel. Also, fuel consumption can be
improved by avoiding overuse of the heater.
■ Checking tire inflation pressure
Make sure to check the tire inflation pressure frequently.
Improper tire inflation pressure can cause poor fuel consump-
tion.
Also, as snow tires can cause lar ge amounts of friction, their use
on dry roads can lead to poor fuel consumption. Use a tire that is
appropriate for the season.
■ Luggage
Carrying heavy luggage can lead to poor fuel consumption.
Avoid carrying unnecessary luggage. Installing a large roof rack
can also cause poor fuel consumption.
■ Warming up before driving
Since the gasoline engine starts up and cuts out automatically
when cold, warming up the engine is unnecessary. Moreover,
frequently driving s hort distances will ca use the engine to
repeatedly warm up, which can lead to poor fuel consumption.

Keys
Using the mechanical keyTo take out the mechanical key,
push the release button and take
the key out.
After using the mechanical key,
store it in the electronic key. Carry
the mechanical key together with
the electronic key. If the electronic
key battery is depleted or the
entry function does not operate
properly, you will need the
mechanical key. (P. 541)
The following keys are provid ed with the vehicle.
Electronic keys
• Operating the smart key
system ( P. 61, 79)
• Operating the wireless remote control function
( P. 85)
• Operating the Remote Air Conditioning System

■
Key number plate
Keep the plate in a safe place such as your wallet, not in the vehicle. In the
event that a mechanical key is lost, a new key can be made at your Toyota
dealer using the key number plate. ( P. 540)
■ When riding in an aircraft
When bringing an electronic key onto an aircraft, make sure you do not
press any buttons on the electronic key while inside the aircraft cabin. If you
are carrying an electronic key in your bag etc., ensure that the buttons are
not likely to be pressed accidentally. Pressing a button may cause the elec-
tronic key to emit radio waves that could interfere with the operation of the
aircraft.

NOTICE
■To prevent key damage
Observe the following:
●Do not drop the keys, subject them to strong shocks or bend them.
● Do not expose the keys to high temperatures for long periods of time.
● Do not get the keys wet or wash them in an ultrasonic washer etc.
● Do not attach metallic or magnetic materials to the keys or place the keys
close to such materials.
● Do not disassemble the keys.
● Do not attach a sticker or anything else to the surface of the electronic key.
● Do not place the keys near objects that produce magnetic fields, such as
TVs, audio systems and glass top ranges, or medical electrical equipment,
such as low-frequency therapy equipment.
■ Carrying the electronic key on your person
Carry the electronic key 3.9 in. (10 cm) or more away from electric appli-
ances that are turned on. Radio waves emitted from electric appliances
within 3.9 in. (10 cm) of the electronic key may interfere with the key, causing
the key to not function properly.
■ In case of a smart key system malf unction or other key-related prob-
lems
Take your vehicle with all the electronic keys provided with your vehicle to
your Toyota dealer.
■ When a vehicle key is lost
If the key remains lost, the risk of vehicle theft increases significantly. Visit
your Toyota dealer immediately with all remaining electronic keys that was
provided with your vehicle.
