Hybrid System
■Hybrid System Indicator
Charge area
Shows regenerative charging.
Hybrid Eco area
Shows that gasoline engine power is
not being used very often.
The gasoline engine will automatically
stop and restart under various condi-
tions.
Eco area
Shows that the vehicle is being driven
in an Eco-friendly manner.
Pow e r a r e a
Shows that an Eco-friendly driving
range is being exceeded (during full
power driving etc.)
● Hybrid System Indicator is displayed when the driving mode is other than the sport
mode.
● By keeping the indicator need le within Eco area, more Eco-friendly driving can be
achieved.
● Charge area indicates regeneration
* status. Regenerated energy will be used to charge
the battery.
*: When used in this manual, “regeneration” refers to the conversion of energy created by the movement of the vehicle into electrical energy.
Your vehicle is a hybrid vehicle. It has characteristics different from conventional vehicles.
Be sure you are closely familiar with the char acteristics of your vehicle, and operate with
care.
The hybrid system combines the use of a gasoline engine and an electric motor (traction
motor) according to driving conditions, improving fuel efficiency and reducing exhaust
emissions.
For details, refer to the “Owner’s Manual”.

■Charging the hybrid battery (traction battery)
If the shift lever is in N, the hybrid battery (traction battery) will not be charged. Always put
the shift lever in P when the vehicle is stoppe d. When driving in heavy traffic, operate the
vehicle with the shift lever in D or S to avoid discharging the battery.
■ Regenerative braking
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 position in D or S.
● The brake pedal is depressed while driving with the shift position in D or S.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move. For
safety, apply the parking brake and make sure to shift the shift position 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.
● Sounds from the hybrid system may be heard when the trunk lid is open.
● Sounds may be heard from the hybrid transmission when the hybrid system starts or
stops.
● Engine sounds may be heard when accelerating sharply.
● Sounds may be heard due to regenerative braking when the brake pedal is depressed.
● Vibration may be felt when the gasoline engine starts or stops.
● Cooling fan sounds may be heard from the air intake vents on the both sides of the rear
seatback.
■Running out of fuel
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 minimum
amount of fuel to add to make the low fuel level warning light go out is about 2.6 gal. [10.0 L,
2.2 Imp.gal.], when the vehicle is on a level surface. This value may vary when the vehicle is
on a slope.)

Theft Deterrent System
■Immobilizer system
The indicator light flashes after the power
switch has been turned off to indicate that
the system is operating.
The indicator light stops flashing after the
power switch has been turned to ACCES-
SORY or ON mode to indicate that the sys-
tem has been canceled.
■Alarm
The alarm uses light and sound to give an alert when an intrusion is detected.
To set the alarm:
Close the doors, trunk and hood, and lock all the doors. The system will be set automatically
after 30 seconds. The indicator light changes from being on to flashing when the system is set.
To deactivate or stop the alarm:
● Unlock the doors or open the trunk.
● Turn the power switch to ACCESSORY or ON mode, or start the hybrid system. (The
alarm will be deactivated or stopped after a few seconds.)

Brake Hold
Turns the brake hold system onThe brake hold standby indicator
(green) comes on. While the system is
holding the brake, the brake hold oper-
ated indicator (yellow) comes on.
The brake hold system keeps the brake applied when the shift lever is in D, S or N with the
system on and the brake pedal has been depressed to stop the vehicle. The system
releases the brake when the accelerator pedal is depressed with the shift lever in D or S to
allow smooth start off.
