Collision Mitigation Brake System (CMBS)
Radar Sensor
EMBLEM
The radar sensor is located behind
the Acura emblem in the front grille.
If the emblem is covered with mud,
dirt, dead leaves, wet snow, etc., or if
you put a sticker on it, the CMBS will
automatically shut off, and the
CMBS indicator on the instrument
panel will come on. You will also see
a CHECK CMBS RADAR SENSOR
message on the multi-information
display for about 5 seconds.

BOLTS
(Do not tamper)
Always keep the emblem clean. If it
gets dirty, clean it with water or a
mild detergent. Never use chemical
solvents or polishing powder.
There are three bolts on the sides of
the radar sensor. Do not tamper with
these bolts, or you may cause the
system to malfunction.
Do not allow anything to impact the
radar sensor or the emblem. If either
of these parts receives a strong
impact, turn off the system by
pressing the CMBS off switch, and
have your vehicle checked by a
dealer. If the front grille ever needs
to be repaired, consult a dealer first.
If the front emblem or the radar
sensor ever needs to be removed,
take your vehicle to a dealer.
