Frontal collision warning
54P000353
If your vehicle gets too close to the vehicle
ahead as described below, the interior
buzzer sounds, the indicator (1) appears
on the information display at the same
time, to promote deceleration.
• The vehicle ahead of you slows down
abruptly.
• Another vehicle cuts in front of you.
Depress the brake pedal, and keep an
appropriate distance from the vehicle
ahead. The buzzer timing of frontal colli-
sion warning varies depending on the vehi-
cle speed and a following distance
between your vehicle and the vehicle
ahead.
There are different frontal collision warning
operations in adaptive cruise control sys-
tem and radar brake support system.
Therefore, the interior buzzer in adaptive
cruise control system sounds a little earlier
than the buzzer in radar brake support sys-
tem. For details of frontal collision warning
in radar brake support system, refer to“Radar brake support system (if equipped)”
in this section.
Handling the radar sensor
For details on radar sensor, refer to “Radar
brake support system” in this section.

WA R N I N G
• Do not use the adaptive cruise con-
trol system in a heavy traffic area
where the frontal collision warning
frequently activates.
• Even if the distance between your
vehicle and the vehicle ahead is
short, frontal collision warning may
not alert you under the following
circumstances:
– The vehicle ahead of you is going
at almost the same speed as, or
faster than your vehicle.
– When the vehicle ahead of you is
going away from your vehicle.
– Right after setting up to the
desired speed.
– While depressing the accelerator
pedal or right after releasing the
pedal.
– While decelerating by depressing
the brake pedal.

tive cruise control system. Contact your
SUZUKI dealer for inspection.
54P000355
Blinks Beep (one time from interior buzzer) The radar brake support system is dis-
abled temporarily because dirt is
detected on the sensor cover, or milli-
meter-waves from the radar sensor
cause diffused reflection. If the message
does not disappear for a while, wipe the
sensor cover with a soft cloth.

Cancelling speed limiter
• To cancel the speed limiter, push “CAN-
CEL” switch (2). The set indicator (6) will
go off.
• To resume the previously set speed,
push “RES +” switch (3) and turn on the
set indicator (6).

If you turn off the speed limiter system, the
previously set speed in the memory is
cleared. Set your speed again.
Radar brake support system
(if equipped)
Radar brake support system measures the
relative velocity of, and distance from, the
vehicle in front of you by radar and then
attempts to avoid a crash by giving warn-
ing and, in the event of a crash, attempts to
reduce damage through brake control.
WA R N I N G
• Radar brake support system has
limits and may not function prop-
erly depending on the driving con-
ditions. Do not rely excessively on
the system and always drive in a
safe manner.
• For safety reasons, do not check
the operation of the system by
yourself.
• Check that all passengers fasten
their seat belts when the vehicle is
being operated.
When the system is activated, there
is a risk of serious injury from
being thrown.

rough surfaces
– On the following slippery sur-
faces
• Frozen or snow-covered sur-
faces
• Over manholes or metal con-
struction plates

NOTE:
• While the system is working, if a vehicle
in front of you moves outside of the
radar’s detection field or the vehicle can
no longer be detected, the system may
stop functioning.
• While the system is working, a braking
sound may be heard even if you do not
depress the brake pedal, but this is nor-
mal.
The radar brake support system, model
MRR1Plus is in compliance with the
essential requirements and other relevant
provisions of Directive 1999/5/EC.Frontal collision warning

Warning brake system
If the driver cannot take or is insufficient to take evasive action such as brake operation
and steering operation after frontal collision warning activates, the system applies brake
lightly.
54P000360
NOTE:
When you operate brake after frontal collision warning activates, the warning brake sys-
tem does not activate. Brake assist system will activate in this case.
CAUTION
In the following conditions, this warning brake system may not activate.
• When another vehicle is already parked on a road in the direction of move-
ment.
• When a vehicle ahead is changing lane and only a part of the vehicle is within
the radar sensor range.
