2018 HONDA CLARITY PLUG IN HYBRID maintenance

Event Data Recorders This vehicle is equipped with an event data recorder (EDR).
The main purpose of an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deployment or hitting a
road obstacle, data that will assist in understanding how a vehicle’s
systems performed. The EDR is designed to record data related
to vehicle dynamics and safety systems for a short period of
time, typically 30 seconds or le ss. The EDR in this vehicle is
designed to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenger safety belts were
buckled/fastened; 3
WARNING California Proposition 65 Warning
Operating, servicing and maintaining a
passenger vehicle or off-road vehicle can
expose you to chemicals including engine
exhaust, carbon monoxide, phthalates, and
lead, which are known to the State of
California to cause cancer and birth defects or
other reproductive harm. To minimize
exposure, avoid breathing exhaust, do not
idle the engine except as necessary, service
your vehicle in a well-ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more
information go to

passenger-vehicle . • How far (if at all) the driver was depressing the accelerator
and/or brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better understanding of the
circumstances in which crashes and injuries occur. NOTE: EDR data
are recorded by your vehicle only if a non-trivial crash situation
occurs; no data are recorded by the EDR under normal driving
conditions and no personal data (e.g., name, gender, age, and
crash location) are recorded. Howeve r, other parties, such as law
enforcement, could co mbine the EDR data with the type of
personally identifying data rout inely acquired during a crash
investigation.
To read data recorded by an ED R, special equipment is required,
and access to the vehicle or the EDR is needed. In addition to the
vehicle manufacturer, other parties, such as law enforcement, that
have the special equipment, can re ad the informatio n if they have
access to the vehicle or the EDR.
The data belongs to the vehicle ow ner and may not be accessed by
anyone else except as legally requir ed or with the permission of the
vehicle owner.
Service Diagnostic Recorders This vehicle is equipped with se rvice-related devices that record
information about powertrain perfo rmance. The data can be used
to verify emissions law requirem ents and/or help technicians
diagnose and solve service problems. It may also be combined with
data from other sources for res earch purposes, but it remains
confidential. Some diagnostic and maintenance information is
uploaded to Honda upon vehicle start up.18 CLARITY PHEV CSS-31TRW6000.book 0 ページ ２０１７年８月３１日　木曜日　午後２時４ ９分

High-Voltage Battery Monitoring System This vehicle is equipped with a monitoring system that compiles
data about your vehicle and drivin g conditions and transmits that
data to Honda at regular intervals as determined at the discretion
of Honda. This data includes information on but not limited to the
following:
● Vehicle location, distance dr iven, warning indicators and
messages, and vehicle speed
● High-Voltage Battery system control and power generation
The system does not record audio or images.
Data collected is used for the sole purposes of technical diagnoses,
preventive maintenance, resear ch and vehicle development.
Neither Honda nor any third party receiving data will use the data
for any other purpose withou t first obtaining customer

Quick Reference Guide
Safety Precautions Do not touch the High Voltage system Attempting to take a system component apart or disconnect one of its wires can cause
severe electrical shock. If the High Voltage system is in need of maintenance or repair, make
sure that the maintenance or repair is carried out by an authorized Honda Clarity Plug-In
Hybrid dealer.
If a crash occurs ● Be careful of electric shock hazard.
u If a severe crash damages your vehicle’s Hi gh Voltage system, there is a possibility of electrical shock due to exposed High Vo ltage
components or wires. If this happens, do not touch any of the High Voltage system components or any of its orange wires.● Avoid contact with High Voltage battery fluid.
u The High Voltage battery contains a flammabl e electrolyte that can leak as a result of a severe crash. Avoid any skin or eye co ntact
with the electrolyte as it is corrosive. If you accidentally come into contact with the electrolyte, rins e the exposed skin or flush your
eyes with copious amounts of water for at least fi ve minutes, then seek medi cal attention immediately.● Use a fire extinguisher for an electrical fire.
u Attempting to extinguish an el ectrical fire with a small quantity of water can be dangerous.● Anytime the vehicle is damaged in an accident, have it repa ired by an authorized Honda Clarity Plug-In Hybrid dealer.
Emergency Shutdown System for the High Voltage SystemIf the vehicle is involved in a crash, the emergency shutdown sy stem will activate depending on the severity of the impact. Whe n the system
activates, the High Voltage system automatica lly shuts down, and the vehicle can no long er move under its own power. To return the High
Voltage system back to normal operation, consult an authorized Honda Clarity Plug-In Hybrid dealer.
Honda collects and recycles High Voltage batteries used in its ve hicles. Consult an authorized Honda Clarity Plug-In Hybrid dea ler for more
information. 18 CLARITY PHEV CSS-31TRW6000.book 19 ページ ２０１７年８月３１日　木曜日　午後２時 ４９分

43uu For Safe Driving u Important Safety Precautions
Continued
Safe Driving
■ Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying
close attention to the road, other vehicles , and pedestrians could lead to a crash.
Remember, situations can change quickly, and only you can decide when it is safe to
divert some attention away from driving.
■ Control your speed
Excessive speed is a major factor in crash injuries and deaths. Generally, the higher
the speed, the greater the risk, but serious injuries can also occur at lower speeds.
Never drive faster than is safe for current conditions, regardless of the maximum
speed posted.
■ Keep your vehicle in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition
frequently, and perform all re gularly scheduled maintenance.
■ Do not leave children unattended in the vehicle
Children left unattended in the vehicle may be injured if they activate one or more
of the vehicle controls. They may also cause the vehicle to move, resulting in a crash
in which the children and/or another pers on(s) can be injured or killed. Also,
depending on the ambient temperature, th e temperature of the interior may reach
extreme levels, which can re sult in injury or death.
Even if the climate control system is on, never leave children in the vehicle
unattended as the climate control system can shut off at any time. 18 CLARITY PHEV CSS-31TRW6000.book 43 ページ ２０１７年８月３１日　木曜日　午後２時 ４９分
