When Driving
Turning on the Power
1.Make sure the parking brake is applied.
2. Depress the brake pedal.1Turning on the Power
Keep your foot firmly on the brake pedal when
starting the power system.
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 fuel cell drops below –4°F
(–20°C), the power system may not start. If the
temperature drops to belo w –22°F (–30°C), the fuel
cells or the High Voltage ba ttery will not operate and,
as a result, the vehicle will not start. Store the vehicle
in a garage or take anothe r measure to insure that
temperature of the fuel cell and High Voltage battery
does not fall below this temperature. If necessary,
consult an authorized Honda Clarity Fuel Cell dealer.

Precautions While Driving
Avoid driving in deep water and on flooded roads. This can damage the power
system or driveline, or cause electrical component failure.
■In Rain1Precautions While Driving
NOTICE
Do not select a shift button while pressing the
accelerator pedal.
NOTICE
The following can damage the rear frames and rear
suspensions. Be careful when driving.
•Backing up the vehicle into a space with a parking
block or road shoulder
•Driving up or down to a different surface level
(such as a road shoulder)
•Driving on a road with potholes
NOTICE
If you repeatedly turn the steering wheel at an
extremely low speed, or hold the steering wheel in
the full left or right position for a while, the electric
power steering (EPS) system heats up. The system
goes into a protective mode, and limits its
performance. The steering wheel becomes harder
and harder to operate. Once the system cools down,
the EPS system is restored.
Repeated operation under these conditions can
eventually damage the system.
If the power mode is set to ACCESSORY while
driving, the power system will shut down and all
steering and brake power a ssist functions will stop,
making it difficult to control the vehicle.

■How to activate the system1Adaptive Cruise Control (ACC) with Low Speed Follow (LSF)
When the MAIN button is pressed, both ACC with
LSF and the Lane Keeping A ssist System (LKAS) are
either turned on or off.
ACC with LSF may not work properly under certain
conditions. 2 ACC with LSF Conditions and Limitations

•On roads with steep downhill sections, as the set
vehicle speed can be exceeded by coasting. In such
cases, ACC with LSF will not apply the brakes to
maintain the set speed.
•On roads with toll collection facilities or other
objects between lanes of traffic, or in parking
areas, or faci lities with driv e through access.
How to use

■Automatic ca ncellation
The beeper sounds and a message appears on the driver information interface and
the head-up display when ACC with LSF is automatically canceled. Any of these
conditions may cause the ACC with LSF to automatically cancel:
• Bad weather (rain, fog, snow, etc.)
• When the radar sensor in the front grille gets dirty.
• An abnormal tire condition is detected, or the tires are skidding.
• Driving on a mountainous road, or driving off road for extended periods.
• Abrupt steering wheel movement.
• When the ABS, VSA ® or CMBS
TM is activated.
• When the ABS or VSA ® system indicator comes on.
• When the vehicle is stopped on a very steep slope.
• When you manually apply the parking brake.
• When the detected vehicle within the AC C with LSF range is too close to your
vehicle.
• The camera behind the rearview mirror, or the area around the camera, including
the windshield, gets dirty.
The ACC with LSF automatic cancellation ca n be also triggered by the following
causes. In these cases, the parking brake will be automatically applied.
• The driver’s seat belt is unfastene d when the vehicle is stationary.
• The vehicle stops for more than 10 minutes.
• The power system is turned off.
1Automatic cancellation
Even though ACC with LSF has been automatically
