The radar sensor is located behind
the Acura emblem in the f ront 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-inf ormation
display f or about 5 seconds.Always keep the emblem clean. If it
gets dirty, clean it with water or a
mild detergent. Never use chemical
solvents or polishing powder.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 of f switch, and
have your vehicle checked by a
dealer. If the f ront grille ever needs
to be repaired, consult a dealer f irst.
There are three bolts on the sides of
the radar sensor. Do not tamper with
these bolts, or you may cause the
system to malf unction. If the f ront emblem or the radar
sensor ever needs to be removed,
take your vehicle to a dealer.

The radar sensor may not always
scan as intended. Here are two
examples:Thetiresarenotcorrectly
maintained. Always make sure the
tire pressures are correct (see
page ), and that the tires are
the correct size and in good
condition (see Tires on page ). Your vehicle is tilted because of a
heavy load in the rear or from
modif ications to the suspension.
Do not overload your vehicle (see
Carrying Cargo on page ), and
do not make any modif ications to
the suspension (see Accessories
and Modif ications on page ). 339

When the CMBS is on, the radar sensor
constantly scans f or vehicles ahead of
you. This means that driving on a road
with a f ew or no vehicles could cause a
CHECK CMBS RADAR SENSOR
message to appear on the multi-
inf ormation display. This is normal
and not a cause f or concern.
