If the air pressure does not go down
after the 10 minute driving, you do not
need to check the pressure any more.

Emergency Power System Off

The POWER button may be used to turn the power system off due to an emergency
situation even while driving. If you must turn the power system off, do either of the
following operations:
• Press and hold the POWER button for about two seconds.
• Firmly press the POWER button three times.

The steering wheel will not lock. However, because turning off the power system
disables the power assist the power system provides to the steering and braking
systems, it will require significantly more physical effort and time to steer and slow
the vehicle. Use both feet on the brake pedal to slow down the vehicle and stop
immediately in a safe place.

The gear position automatically changes to

(

P after the vehicle comes to a complete

stop. Then, the power mode changes to VEHICLE OFF.

Emergency Power System Off

Do not press the button while driving unless it is
absolutely necessary for the power system to be
turned off.

Jump Starting

Turn off the power to electric devices, such as the audio and lights. Turn off the
power system, then open the hood.

1. Open the battery terminal cover.

2. Connect the first jumper cable to your

vehicle’s 12-volt battery + terminal.

3. Connect the other end of the first jumper

cable to the booster battery + terminal.

If you use a booster battery, only use a
12-volt booster battery.

When using an automotive battery
charger, select a charging voltage lower
than 15-volts. Check the charger manual
for the proper setting.

4. Connect the second jumper cable to the

booster battery - terminal.

Jump Starting Procedure

Jump Starting

Securely attach the jumper cable clips so that they do
not come off when the power system vibrates. Also
be careful not to tangle the jumper cables or allow
the cable ends to touch each other while attaching or
detaching the jumper cables.

12-volt Battery performance degrades in cold
conditions and may prevent the power system from
starting.

WARNING

A 12-volt battery can explode if you do not
follow the correct procedure, seriously
injuring anyone nearby.

Keep all sparks, open flames, and smoking
materials away from the 12-volt battery.

Next thing to do

1. Check that the cooling fan is operating and

turn the power system off once the Stop
Driving When Safe. Engine
Temperature Too Hot message
disappears.

If the cooling fan is not operating,
immediately turn the power system off.

2. Once the engine has cooled down, inspect

the coolant level and check the cooling
system components for leaks.

If the coolant level in the reserve tank is
low, add coolant until it reaches the
MAX mark.

If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.

■

Last thing to do

Once the engine has cooled sufficiently, turn the power system on.
If the Stop Driving When Safe. Engine Temperature Too Hot message does not
appear, resume driving. If it appears again, contact an authorized Honda Clarity
Plug-In Hybrid dealer for repairs.

If the coolant is leaking, contact an authorized Honda
Clarity Plug-In Hybrid dealer for repairs.

Use water as an emergency/temporary measure only.
Have an authorized Honda Clarity Plug-In Hybrid
dealer flush the system with proper antifreeze as
soon as possible.

WARNING

Removing the radiator cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.

Always let the engine and radiator cool
down before removing the radiator cap.
