Accessories
When installing accessories, check the following:
• Do not install accessories on the windshield. They can obstruct your view and
delay your reaction to driving conditions.
• Do not install any accessories over areas marked SRS Airbag, on the sides or backs
of the front seats, on front or side pillars, or near the side windows.
Accessories installed in these areas may interfere with proper operation of the
vehicle’s airbags or may be propelled into you or another occupant if the airbags
deploy.
• Be sure electronic accessories do not over load electrical circuits or interfere with
proper operation of your vehicle.
2 Fuses P. 657
•Before installing any electron ic accessory, have the installer contact a dealer for
assistance. If possible, have a d ealer inspect the final installation.

Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Honda pa rts or accessories that may have a similar
effect.
Even minor modifications to vehicle systems can affect overall vehicle performance.
Always make sure all equipment is properly installed and maintained, and do not
make any modification to your vehicle or its systems that might cause your vehicle
to no longer meet federal, state, pr ovince, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1 962 connector) installed on this vehicle
is intended to be used with automobile system diagnostic devices or with other
devices that Honda has approved. Use of any other type of device may adversely
affect the vehicle’s electronic systems or allow them to be compromised, possibly
resulting in a system malfunction, drained battery, or other unexpected problems.
Do not modify or attempt to repair your vehicle’s high-voltage hybrid power system
or otherwise modify vehicle electrical syst ems. Disassembling or modifying electrical
equipment can result in a crash or a fire.
If you ever need to replace your vehicle’ s high-voltage battery assembly outside of
warranty coverage, we highly recommend that you only use a genuine Honda high-
voltage battery assembly. Genuine Honda high-voltage battery assemblies are
designed to work with your vehicle’s hybrid power system and have been designed,
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have b een similarly designed, engineered and
manufactured, and installation of such assemblies could result in overcharging, fires,
loss of power, or other conditions that may increase the likelihood of a crash or
injury.

NOTICE
Do not operate the temporary tire repair kit
compressor for more than 15 minutes. The
compressor can overheat and become permanently
damaged.
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begin to rise again as the
tire is inflated with air. This is normal. To accurately
measure the air pressure usin g the gauge, turn the air
compressor off only after the sealant injection is
complete.

Running the engine with the vehicle in an
enclosed or even partly enclosed area can
cause a rapid build-up of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.

cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u
When using an automotive battery charger
to boost your 12-volt battery, select a
lower charging voltage than 15-volt. Check
the charger manual for the proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1If the 12-Volt Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
12-volt battery performa nce degrades in cold
conditions and may prevent the engine from starting.
3WARNING
