Charge area
Shows regeneration
* status. Regenerated energy will be used to charge the hybrid
battery (traction battery).
*: When used in this manual, regeneration refers to the conversion of energy created by
the movement of the vehicle into electrical energy.
Hybrid Eco area
Shows that gasoline engine power is not being used very often.
The gasoline engine will automatically stop and restart under various conditions.
Eco area
Shows that the vehicle is being driven in an Eco-friendly manner.
By keeping the bar display within Eco area, more Eco-friendly driving can be achieved.
Power area
Shows that an Eco-friendly driving range is being exceeded (during full power driving
etc.)
Hybrid System
Your vehicle is a Hybrid Electric Vehicle. It has characteristics different from conventional
vehicles. Be sure you are closely familiar with the characteristics of your vehicle, and
operate it with care.
The hybrid system combines the use of a gaso line engine and an electric motor (traction
motor) according to driving conditions, improv ing fuel efficiency and reducing exhaust
emissions.
For details, refer to the “OWNER’S MANUAL”.

If the shift lever is in N, the hybrid battery (traction battery) will not be charged even when
the engine is running. Therefore, if the vehicle is left with the shift lever in N for a certain
amount of time, the hybrid battery (traction battery) will discharge, and this may result in the
vehicle not being able to start.
In the following situations, kinetic energy is converted to electric energy and deceleration
force can be obtained in conjunction with the recharging of the hybrid battery (traction bat-
tery).
● The accelerator pedal is released while driving with the shift lever in D or S.
● The brake pedal is depressed while driving with the shift lever in D or S.
There may be no engine sound or vibration even though the vehicle is able to move with the
“READY” indicator is illuminated. For safety, apply the parking brake and make sure to shift
the shift lever to P when parked.
The following sounds or vibrations may occur when the hybrid system is operating and are
not a malfunction:
● Motor sounds may be heard from the engine compartment.
● Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
● Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear seats, when the hybrid system is started or
stopped.
● Sounds from the hybrid system may be heard when the back door is open.
● Sounds may be heard from the hybrid transmission when the gasoline engine starts or
stops, when driving at low speeds, or during idling.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is depressed or
as the accelerator pedal is released.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vent under the right side of the rear
seat.

When the vehicle has run out of fuel and the hybrid system cannot be started, refuel the
vehicle with at least enough gasoline to make the low fuel level warning light go off. If there is
only a small amount of fuel, the hybrid system may not be able to start. (The standard amount
of fuel is about 1.8 gal. [7.0 L, 1.5 Imp.gal.], when the vehicle is on a level surface. This value
may vary when the vehicle is on a slope. Add extra fuel when the vehicle is inclined.)
A message is automatically displayed when a ma lfunction occurs in the hybrid system or an
improper operation is attempted.
If a warning message is shown on the multi-
information display, read the message and
follow the instructions.

1Insert the retaining hooks (clips) into
the floor mat eyelets.
2Turn the upper knob of each retaining
hook (clip) to secure the floor mats in
place.
Always align the marks .
The shape of the retaining hooks (clips) may differ from that shown in the illustration.
Floor Mat Installation
Use only floor mats designed specifically for vehicles of the same model and model year
as your vehicle. Fix them securely in place onto the carpet.

*: If equipped
To take out the mechanical key, push the
release button and take the key out.
The mechanical key can only be inserted in
one direction, as the key only has grooves
on one side. If the key cannot be inserted in
a lock cylinder, turn it over and re-attempt
to insert it.
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.
