Accessories and Modifications
Modifying Your Vehicle
Removing parts from your vehicle,
or replacing components with
non-Honda components could
seriously affect your vehicle's
handling, stability, and reliability.
Some examples are:
Lowering the vehicle with a non-
Honda suspension kit that
significantly reduces ground
clearance can allow the
undercarriage to hit speed bumps
or other raised objects, which
could cause the airbags to deploy.
Raising your vehicle with a
non-Honda suspension kit can
affect the handling and stability.
Non-Honda wheels, because they
are a universal design, can cause
excessive stress on suspension
components.

Larger or smaller wheels and tires
can interfere with the operation of
your vehicle's anti-lock brakes and
other systems.
Modifying your steering wheel or
any other part of your vehicle's
safety systems could make the
systems ineffective.
If you plan to modify your vehicle,
consult your dealer.
