If dirt is detected on the radar sensor
cover, the radar brake support system will
stop functioning and the radar brake sup-
port system warning light (3) will come on,
and “RADAR BRAKE SUPPORT: NOT

• Always keep the sensor cover sur-
face clean. When it is dirty, wipe it
down with a soft cloth that will not
scratch the cover. Also, when the
following things are covering or
attached to the sensor cover, they
will be detected as dirt and the
radar will either take more time to
detect things or it will not detect
things at all. If this happens, the
system will not function normally
and unexpected accidents may
occur.
– Plastic bags (transparent, semi-
transparent, colored or metal-
coated)
– Rain, snow, etc.
• Observe the following instructions
in order to keep the radar sensor
functioning properly. If mishandled,
the radar sensor cannot accurately
detect a vehicle in front of you, the
system will not function properly
and unexpected accidents may
occur.
– Do not strike the radar sensor
forcefully. If there is a minor
crash and the radar sensor is
damaged or hindered, have it
inspected by an authorized
SUZUKI dealer.

– Do not stick or affix anything to
the sensor cover, not even clear
items.
– Do not do any customizing, coat-
ing or applying of non-genuine
SUZUKI parts to the radiator grill
or front bumper. For repairs and
parts replacement, contact an
authorized SUZUKI dealer.
– Do not remove or disassemble
the radar sensor or any sur-
rounding parts.
– Do not sit on or lean against the
front bumper.
– When using a high pressure car
washer, do not point the nozzle
at, or around, the sensor cover.
– Do not push other vehicle or
objects with the front bumper

When dirt is detected on the sensor
cover
If the message (4) does not disappear,
perform the following procedure.
1) Find a safe place to park and change
the ignition switch to “LOCK” position or
the ignition mode to “LOCK” (OFF) by
pressing the engine switch.
2) Clean the sensor cover with a soft
cloth.
3) Change the ignition switch to “ON”
position or the ignition mode to “ON” by
pressing the engine switch.
4) Check that the message (4) appears for
about 3 seconds and then disappears.
• If you clean the sensor cover and drive
the vehicle, but the message (4) appears
again, there might be another problem.
Contact an authorized SUZUKI dealer
for further assistance.NOTE:
In the following situations, the radar brake
support system warning light (3) may come
on, the message (4) may appear and the
radar brake support system may be deacti-
vated automatically, even if there is no dirt
on the sensor cover.
• In a tunnel
• A road where there are concrete walls
on both sides
• A road where there are metal fences on
one side
• Around overpasses or grade separated
crossings
• When there is bad weather such as
heavy rain or snow
• A road where there are puddles
In these situations, the radar brake support
system is stop functioning temporarily,
because millimeter-waves emanating from
the radar sensor cause diffused reflection
and a position of the vehicle in front of you
cannot be detected correctly.
If you drive the vehicle for about 2 minutes
after the above situations have improved,
these indicator and message will turn off
and the radar brake support system will
turn back on.

• An obstacle within about 20 cm (8 in)
from a sensor or just below a sensor is
not detectable.
• The sensors can detect an obstacle up
to about 1 m (3 ft) from the front of the
vehicle, or about 1.5 m (5 ft) from the
rear of vehicle.
