Situations where radar will not acti-vate properly
Under the following situations, there is a
high possibility that the system will not acti-
vate.
• When the engine is off (except when the
engine is automatically stopped by the
ENG A-STOP system)
• When the gearshift lever is in the reverse
gear
• When facing an oncoming vehicle
• When the following switches are pushed
and the system is turned off:
– Radar brake support OFF switch
– ESP
® OFF switch
• When the system is temporarily stopped
or malfunctioning, some of the following
indicator and messages will come on:
– The radar brake support system warn-
ing light
– “RADAR BRAKE SUPPORT SYS
INSPECTION REQUIRED” message
– “RADAR BRAKE SUPPORT FCN
TEMPORARILY DISABLED” message
– “RADAR BRAKE SUPPORT: NOT
ACTIVE BY SENSOR.” message
Situations where radar may not activate properly
Under the following situations, the radar
may not detect a vehicle in front of you cor-
rectly and the system may not activate.
• When the radar sensor cover is covered
in snow, water or dirt
• When there is bad weather such as
heavy rain or fog, a blizzard or sand-
storm or when the vehicle in front of you
is surrounded by water, snow or sand
• When you are operating on a narrow
road
• When another vehicle jumps out sud-
denly
• When you suddenly accelerate and
approach the vehicle in front of you,
such as when you overtake the vehicle
in front of you
• When swerving
• When the vehicle cannot move in a
straight manner without consistently
steering, due to an accident or break-
down
54P000322
• When you take evasive action with the
steering wheel or accelerator pedal
54P000323
• When only a part of the vehicle in front of
you is within the radar’s detection field,
such as when operating on a curvy road

Frontal collision warning
When you are operating at a speed of
approximately 5 km/h (3 mph) or over and
there is a risk of a frontal crash, a warning
will work.
• The interior buzzer will intermittently
beep, the radar brake support system
warning light (1) will blink rapidly, and the
indication (2) will appear.
54P000333
• When the frontal collision warning
sounds, depending on the distance from
the vehicle in front of you and driving
conditions, take evasive action with the
steering wheel or brake pedal.FAR/NEAR setting switch
You can change the timing of when the
frontal collision warning sounds, while the
system is functioning, by using the FAR/
NEAR setting switch.
• Given the same relative velocity and dis-
tance of the vehicle in front of you, the
FAR setting will respond faster than the
NEAR setting. We recommend that you
normally use the FAR setting.
54P000334
• Press the FAR/NEAR setting switch to
change the frontal collision warning tim-
ing to NEAR (3).
• Press the FAR/NEAR setting switch
again to change the frontal collision
warning timing back to FAR (4).
• Whenever you press the FAR/NEAR set-
ting switch, the interior buzzer will beep
and NEAR or FAR will appear on the
information display for several seconds.

Brake assist system
When you are operating at a speed of
approximately 5 km/h (3 mph) or over and
there is a high probability of a frontal crash,
the brake assist system provides more
powerful braking when you slam down on
the brake pedal.

ing, the radar brake support system
warning light (1) will blink rapidly, and the
indication (2) will appear.
54P000335
Automatic brake system
When a frontal crash is judged to be
unavoidable at speeds between approxi-
mately 5 km/h to 30 km/h (3 mph to 9 mph),
the brakes will powerfully operate automati-
cally and will attempt to avoid the crash or
reduce the damage of the crash.
• When the automatic brake system is acti-
vated at a speed of approximately 15 km/h
(9 mph) or under, crashes may be avoid-
able.
• While the automatic brake system is
working, the radar brake support system
warning light (1) will blink rapidly, the
indication (2) will appear, and the brake
lights will be turned on.

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
ACTIVE BY SENSOR.” message (4) will

• 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 you pull out of a parking
area.

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.
