uuHonda Sensing ®u Traffic Sign Recognition System
Driving
If the system does not detect any traffic si gns while you are driving, the image below
may appear.1 Traffic Sign Recognition System
To help reduce the likel ihood that high interior
temperatures will cause the camera’s sensing system
to shut off, when parking, find a shady area or face
the front of the vehicle away from the sun. If you use
a reflective sun shade, do not allow it to cover the
camera housing.
Covering the camera can concentrate heat on it.
If the Some Driver Assist Systems Cannot
Operate: Camera Temperature Too High message
appears, the traffic sign recognition system does not
work, and will be displayed.
•Use the climate control system to cool down the
interior and, if necessary, also use defroster mode
with the air flow directed towards the camera.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the camera.
If the Some Driver Assist Systems Cannot
Operate: Clean Front Windshield message
appears, the traffic sign recognition system does not
work, and will be displayed.
Park your vehicle in a safe place, and clean the
windshield. If the message does not disappear after
you have cleaned the winds hield and driven for a
while, have your vehicl e checked by a dealer.

uuChecking and Maintaining Tires uDOT Tire Quality Grading (U.S. Vehicles)
Continued
Maintenance
DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle m eet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on th e tire sidewall
between tread shoulder and maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested un der controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practi ces and differences in road
characteristics and climate.
■Uniform Tire Quality Grading
■Treadwear
1 Uniform Tire Quality Grading
For example:
Treadwear 200
Traction AA
Temperature A
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant system only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust a nd pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Air Conditioning
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:

If the airflow from the climate control system
deteriorates noticeably, and the windows fog up

contact a dealer for replacement.
