• Make sure there are no people or ob jects behind or around the vehicle.
u There are blind spots from the inside.
• Disconnect the charging cable.■ Exterior Checks 1 Exterior Checks NOTICE
When doors are frozen s hut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert the key if the water
freezes in the hole.
Heat from the engine and exhaust can ignite
flammable material s left under the hood, causing a
fire. If you’ve parked y our vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.19 CLARITY PHEV-31TRW6100.book 372 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

383 uu When Driving u Transmission
Driving
If there is a strong impact with something under the vehicle, stop in a safe location.
Check the underside of the vehicle for damage or any fluid leaks, and contact an
authorized Honda Clarity Plug-In Hybrid dealer.
Transmission As with a conventional gasoline-powered ve hicle with an auto matic transmission,
this vehicle will creep.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pedal wh ile driving uphill may cause the vehicle
to react similar to an automatic transmissio n vehicle, unexpected ly increasing vehicle
speed. Depress the accelerator pedal carefu lly, especially on slippery roads and
curves.■ Other Precautions
■ Creeping
■ Kickdown 1 Precautions While Driving
Do not press the ( N
button, as you will lose
regenerative braking (and ac celeration) performance.
During the first 600 miles (1,000 km) of operation,
avoid sudden acceleration or full throttle operation so
as to not damage the engine or powertrain.
Avoid hard braking for the first 200 miles (300 km).
You should also follow this when the brake pads are
replaced.19 CLARITY PHEV-31TRW6100.book 383 ページ ２０１８年１０月２５日　木曜日　午後２時２９分

425uu When Driving u Vehicle Stability Assist ® (VSA ® ), aka Electronic Stability Control (ESC), System
Continued
Driving
Vehicle Stability Assist ® (VSA ® ), aka Electronic
Stability Control (ESC), System VSA ® helps to stabilize the vehicle during corn ering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine and motor output and selectively applying the
brakes.
When VSA ® activates, you may notice that the
engine and motor do not respond to the
accelerator. You may also notice some noise
from the hydraulic system. You will also see
the indicator blink.
■ VSA ® Operation 1 Vehicle Stability Assist ® (VSA ® ), aka Electronic Stability Control
(ESC), System
The VSA ® may not function properl y if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the air pressures as specified.
When the VSA ® system indicator comes on and stays
on while driving, there ma y be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by an authorized
Honda Clarity Plug-In Hybr id dealer immediately.
The indicators for the Vehicle Stability Assist ® (VSA ® )
System, Vehicle Stability Assist ® (VSA ® ) OFF, low tire
Pressure/TPMS and Collision Mitigation Braking
System TM
(CMBS TM
) may come on along with a
message in the driver information interface after
reconnecting the 12-volt battery. Drive a short
distance at more than 12 mph (20 km/h). The
indicator should go off. If it does not, have your
vehicle checked by an aut horized Honda Clarity Plug-
In Hybrid dealer.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and corner at speeds appropriate
for the conditions and alwa ys leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.VSA ® System

Driving This button is on the driv er side control panel.
To partially disable VSA ® functionality/
features, press and hold it until you hear a
beep.
Your vehicle will have normal braking and
cornering ability, but traction control function
will be less effective.
To restore VSA ® functionality/features, press
the (VSA ® OFF) button until you hear a
beep.
VSA ® is turned on every time you turn the
power system on, even if you turned it off the
last time you drove the vehicle.■ VSA ® On and Off 1 Vehicle Stability Assist ® (VSA ® ), aka Electronic Stability Control
(ESC), System
In certain unusual conditions when your vehicle gets
stuck in shallow mud or fr esh snow, it may be easier
to free it with the VSA ® temporarily switched off.
When the button is pressed, the traction control
function becomes less effective. This allows for the
wheels to spin more freely at low speed. You should
only attempt to free your vehicle with the VSA ® off if
you are not able to free it when the VSA ® is on.
Immediately after freeing your vehicle, be sure to
switch VSA ® on again. We do not recommend driving
your vehicle with the VSA ® system switched off.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediately after turning the power
system on or while driv ing. This is normal.VSA ® OFF IndicatorU.S. models

440 uu Braking u Anti-lock Brake System (ABS)
Driving Anti-lock Brake System (ABS) Helps prevent the wheels from locking up, an d helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distributi on (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distri bution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pe dal. This is sometimes referred to as
“stomp and steer.”
■ ABS operation
You may hear an operating noise when the ABS is working. Depress the brake pedal
and keep holding the pedal firmly down. On dry pavement, you will need to press
on the brake pedal very hard before the AB S activates. However, you may feel the
ABS activate immediately if you are trying to stop on snow or ice.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.■ ABS 1 Anti-lock Brake System (ABS) NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS wi ll not be operating. Have
your vehicle checked by an authorized Honda Clarity
Plug-In Hybrid dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
• You are driving on rough or uneven road surfaces,
such as gravel or snow.
• The tires are equipped with tire chains.
The following may be observed with the ABS system:
• Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
power system has been turned on and while the
vehicle accelerates.
• Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.19 CLARITY PHEV-31TRW6100.book 440 ページ ２０１８年１０月２５日　木曜日　午後２時２９分
