Maintenance
• Keep sufficient distance between the cleaning nozzl e and the vehicle body.
• Take particular care around the windows. Standing too close may cause water to
enter the vehicle interior.
• Do not spray high pressure water directly into the engine compartment. Instead,
use low pressure water and a mild detergent.
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 be stained or the coating may peel. Promptly wipe it away using a soft cloth and
clean water.
Wipe using a glass cleaner.

Modifications
Do not modify your vehicle in a manner that may affect its handling, stability, or
reliability, or install non-genuine Acura parts 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 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, prov ince, 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 Acura has appr oved. 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 systems. 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 Acura high-
voltage battery assembly. Genuine Acur a 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 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
