uuCleaning uExterior Care
Maintenance
A good coat of automotive body wax helps protect your vehicle’s paint from the
elements. Wax will wear off over time and expose your vehicle’s paint to the
elements, so reapply as necessary.
If you get gasoline, oil, engine coolant, or battery fluid on resin-coated parts, they
may stain or the coating may peel. Prompt ly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.
Aluminum is susceptible to deterioration caused by salt and other road
contaminants. When necessary, as early as possible use a sponge and mild detergent
to wipe away these contaminants. Do no t use a stiff brush or harsh chemicals
(including some commercial wheel cleaners). These can damage the protective finish
on aluminum alloy wheels, resulting in corrosion. Depending on the type of finish,
the wheels also may lo se their luster or appear burn ished. To avoid water stains,
wipe the wheels dry with a cloth while they are still wet.

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 system s 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

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
