Security System
Immobilizer System
The immobilizer system prevents a key that has not been pre-registered from 
starting the power system. Each key cont ains electronic transmitters that use 
electronic signals to verify the key.
Pay attention to the follo wing when pressing the POWER button:
• Do not allow objects that emit  strong radio waves near the POWER button.
• Make sure the key is not covered  by or touching a metal object.
• Do not bring a key from another vehicle’s immobilizer system near the  POWER 
button.
• Do not put the key near magnetic items.  Electronic devices, such as televisions 
and audio systems emit strong magnetic  fields. Note that even a key chain can 
become magnetic.
Security System Alarm
The security system alarm activates when  the trunk, hood or doors are forcibly 
opened. The alarm does not activate if the trunk or doors are opened with the key, 
remote transmitter or smart entry system.
However, the alarm activates if a door is op ened with the key and then the hood is 
opened before the power mode is set to ON.
■When the security system alarm activates
The horn sounds intermittently  and some exterior lights flash.
■To deactivate the security system alarm
Unlock the vehicle using the key, remote  transmitter or smart entry system. The 
system, along with the horn and flashing lights, is deactivated.

Driving
When Driving
Turning on the Power
1.Make sure the parking brake is applied.
2. Depress the brake pedal.1When Driving
When you set the power mode to ON, you may feel 
as if the brake pedal is sinking down. This is normal.
1Turning on the Power
Keep your foot firmly on the brake pedal when 
starting the power system.
The engine is harder to st art in cold weather and in 
thinner air found at altitudes above 8,000 feet (2,400 
meters).
When turning on the power system in cold weather, 
turn off all electrical accessories such as the lights, 
climate control system, and  rear defogger in order to 
reduce 12-volt battery drain.
If the temperature of the High Voltage battery drops 
below approximately –22°F (–30°C), the power 
system will not start, the  High Voltage battery will not 
operate and, as a result, the vehicle will not start. 
Store the vehicle in a gara ge or take another measure 
to insure that temperature of the High Voltage 
battery does not fa ll below this temperature. If 
necessary, consult an author ized Honda Clarity Plug-
In Hybrid dealer.
