Accessories and Modifications
Before installing any electronic
accessory, have the installer
contact your dealer for assistance.
If possible, have your dealer
inspect the final installation.
Do not install accessories on the
side pillars or across the rear
windows. Accessories installed in
these areas may interfere with
proper operation of the side
curtain airbags.

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, stability, and
reliability.
Non-Honda wheels, because they
are a universal design, can cause
excessive stress on suspension
components and will not be
compatible with the tire pressure
monitoring system (TPMS).
2011 Ridgeline
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.
