Power Source and Charging Electric Source When the High Voltage battery is sufficiently charged, the vehicl e is propelled solely by the electric motor. When the remainin g power of 
the High Voltage battery drops to a certain level, the vehicle switches to HV.
u To maintain charge levels, you can, at any time, use the  HV  button to switch the vehicle to HV.
2 Switching to HV  (P16)
u If the High Voltage battery charge drops below levels that are  necessary for the vehicle to run  in Electric, you can enable cha rging of 
the battery by pressing and holding the  HV  button.
2 Switching to HV CHARGE  (P17)
Hybrid Source In hybrid, the electric motor receives powe r either from the High Voltage battery or  from the generator which is driven by the  engine, or 
from both the High Volt age battery and generator.
Engine Source When the vehicle is driving under light load within a certain  speed range, the engine provides direct power to the wheels.
Charging the High Voltage Battery  (P455)
There are a number of ways to charge the High Voltage battery. You can:
● Use the Level 2 240V charger, or the portable charging cable located in the trunk.
● Use a public charging station.
● Enable HV Charge and let the battery charge while the vehicle is being driven.
When charging from an external source, you ca n schedule the start and end time for charging. 
(P467)
Regenerative Energy and Regenerative Braking When the vehicle is decelerating or descending a hill, the electric motor acts as a generator that recovers 
a portion of the energy that was used to accelerate the vehicle.
The regenerative force that the electric motor applie s to the wheels when it is  in regenerative mode 
helps to slow the vehicle down in a manner similar to engine braking which is used on conventional 
vehicles. If you want to slow the vehicle down at a faster rate without using the brakes, you can use the 
deceleration paddle selector to increase the resistive force. 18 CLARITY PHEV CSS-31TRW6000.book  15 ページ  2017年8月31日 木曜日 午後2時 49分

Quick Reference Guide
What to Do If Why do I hear an operating 
noise when applying the 
brakes? This can occur when the ABS activates and does not indicate a 
problem. Apply firm, steady pressure on the brake pedal. Never 
pump the brake pedal. 2 Anti-lock Brake System (ABS)  (P437)
The rear door cannot be 
opened from inside the 
vehicle. Why? Check if the childproof lock is in 
the lock position. If so, open the 
rear door with the outside door 
handle.
To cancel this function, slide the 
lever up to the unlock position.
Why do the doors lock 
after I unlocked the doors? If you do not open the doors within 30 seconds, the doors are 
relocked automatically for security.
Why does the beeper

400 uu When Driving u Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
Driving Adaptive Cruise Control  (ACC) with Low Speed 
Follow (LSF) Helps maintain a constant vehicle speed an d a set following-interval behind a vehicle 
detected ahead of yours and, if the detect ed vehicle comes to a stop, can decelerate 
and stop your vehicle, without you having  to keep your foot on the brake or the 
accelerator.
When ACC with LSF slows your vehicle by  applying the brakes, your vehicle's brake 
lights will illuminate. 1 Adaptive Cruise Control (ACC)  with Low Speed Follow (LSF)
Important Reminder
As with any system, there are limits to ACC with LSF. 
Use the brake pedal whenever necessary, and always 
keep a safe interval betw een your vehicle and other 
vehicles.

■ There is no vehicle ahead
Your vehicle maintains the set speed without 
having to keep your foot on the brake or 
accelerator pedal.
If there previously was a vehicle detected 
ahead that kept your ve hicle from traveling at 
the set speed, ACC with LSF accelerates your 
vehicle to the set speed, and then maintains it.
■ When you depress the accelerator pedal
You can temporarily increase the vehicle speed . In this case, there is no audible or 
visual alert even if a vehicl e is in the ACC with LSF range.
ACC with LSF stays on unless you cancel it . Once you release th e accelerator pedal, 
the system resumes an appropriate speed fo r keeping the followi ng-interval while a 
vehicle ahead is within  the ACC with LSF range.
■ A vehicle detected ahead  is within ACC with LSF  range and slows to a stop
Your vehicle also stops, automatically. The 
Stopped  message appears on the driver 
information interface.
When the vehicle ahead  of you starts again, 
the vehicle icon on the driver information 
interface blinks. If you press the  RES/+  or 
−/SET  button, or depress the accelerator 
pedal, ACC with LSF operates again within the 
prior set speed. 1 When in Operation
