Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Honda parts or accessories that may have a similar
effect.
Even minor modifications to vehicle system s can affect overall vehicle performance.
Always make sure all equipment is prop erly 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, province, territory, and local regulations.
The on-board diagnostic port (OBD-II/SAE J1962 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, draine d 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 systems. Disassemb ling 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 hybr id power system and have been designed,
engineered and manufactured to avoid overcharging situations. Non-genuine high-
voltage battery assemblies may not have be en 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.
