VEHICLE-TO-VEHICLE
DISTANCE CONTROL MODE
OPERATION
The vehicle-to-vehicle distance control mode
is designed to maintain a selected distance
from the vehicle in front of you and can re-
duce the speed to match a slower vehicle
ahead. The system will decelerate the vehicle
as necessary and if the vehicle ahead comes
to a stop, the vehicle decelerates to a stand-
still. However, the ICC system can only apply
up to 40% of the vehicle’s total braking
power.
This system should only be used when traffic
conditions allow vehicle speeds to remain
fairly constant or when vehicle speeds
change gradually. If a vehicle moves into the
traveling lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer because
the ICC system cannot decelerate the vehicle
quickly enough. If this occurs, the ICC system
will sound a warning chime and blink the
system display to notify the driver to take
necessary action.The system will cancel and a warning chime
will sound if the speed is below approxi-
mately 15 mph (24 km/h) and a vehicle is not
detected ahead. The system will also disen-
gage when the vehicle goes above the maxi-
mum set speed.
For additional information, refer to “Ap-
proach warning” in this section.
The following items are controlled in the
vehicle-to-vehicle distance control mode:
∙ When there are no vehicles traveling ahead, the vehicle-to-vehicle distance
control mode maintains the speed set by
the driver. The set speed range is be-
tween approximately 20 and 90 mph (32
and 144 km/h).
∙ When there is a vehicle traveling ahead, the vehicle-to-vehicle distance control
mode adjusts the speed to maintain the
distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the sys-
tem. The system will cancel once it judges
a standstill with a warning chime. ∙ When the vehicle traveling ahead has
moved out from its lane of travel, the
vehicle-to-vehicle distance control mode
accelerates and maintains vehicle speed
up to the set speed.
The ICC system does not control vehicle
speed or warn you when you approach sta-
tionary and slow moving vehicles. You must
pay attention to vehicle operation to main-
tain proper distance from vehicles ahead
when approaching toll gates or traffic con-
gestion.

∙ When a wheel is slipping (To use the ICC system, make sure the wheels are no lon-
ger slipping.)
1System set display with vehicle ahead
2System set display without vehicle ahead
The driver sets the desired vehicle speed
based on the road conditions. The ICC sys-
tem maintains the set vehicle speed, similar to
standard cruise control, as long as no vehicle
is detected in the lane ahead. The ICC system
displays the set speed.
Vehicle detected ahead
When a vehicle is detected in the lane ahead,
the ICC system decelerates the vehicle by
controlling the throttle and applying the
brakes to match the speed of a slower vehicle ahead. The system then controls the vehicle
speed based on the speed of the vehicle
ahead to maintain the driver selected dis-
tance.
NOTE:
∙ The stop lights of the vehicle come on
when braking is performed by the ICC
system.
∙ When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the vehicle
ahead detection indicator comes on. The ICC
system will also display the set speed and
selected distance.
Vehicle ahead not detected
When a vehicle is no longer detected ahead,
the ICC system gradually accelerates your
vehicle to resume the previously set vehicle
speed. The ICC system then maintains the set
speed.
When a vehicle is no longer detected, the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system con-
trols the distance to that vehicle.

5-92Starting and driving

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and ICC sys-
tem display. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between vehicles
is increasing.
∙ When a vehicle cuts in near your vehicle. The warning chime will not sound when:
∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, over- riding the system.
NOTE:
The approach warning chime may sound and
the system display may blink when the ICC
sensor detects objects on the side of the ve-
hicle or on the side of the road. This may
cause the ICC system to decelerate or accel-
erate the vehicle. The ICC sensor may detect
these objects when the vehicle is driven on
winding roads, narrow roads, hilly roads, or
when entering or exiting a curve. In these
cases you will have to manually control the
proper distance ahead of your vehicle.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shift lever is not in the D (Drive) position or Manual mode
∙ When the electronic parking brake sys- tem is applied
∙ When the VDC system is turned off
∙ When VDC operates
∙ When distance measurement becomes impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
∙ In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the presence
of the vehicle ahead nor the vehicle-to-
vehicle distance is detected.
∙ Pay special attention to the distance be- tween your vehicle and the vehicle ahead
of you or a collision could occur. ∙ Always confirm the setting in the ICC
system display.
∙ Do not use the conventional (fixed speed) cruise control mode when driving under
the following conditions:
– When it is not possible to keep the ve- hicle at a set speed
– In heavy traffic or in traffic that varies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice, etc.)
– In very windy areas
∙ Doing so could cause a loss of vehicle con- trol and result in an accident.

4ProPILOT Assist switch
The ProPILOT Assist system has the follow-
ing two functions: 1. Intelligent Cruise Control (ICC)
The ICC system can be set to one of two
cruise control modes:
∙ Conventional (fixed speed) cruise
control mode: For cruising at a preset
speed
NOTE:
Steering assist is not available in the conven-
tional (fixed speed) cruise control mode. ∙Vehicle-to-vehicle distance control
mode: The ICC system maintains a se-
lected distance from the vehicle in
front of you within the speed range of
0 to 90 mph (0 to 144 km/h) up to the
set speed. The set speed can be se-
lected by the driver between 20 to
LSD2996
Starting and driving5-109

90 mph (32 to 144 km/h). When the
vehicle ahead slows to a stop, your
vehicle gradually decelerates to a
standstill. When the vehicle is stopped,
the ICC system maintains braking
force to keep your vehicle stopped.
NOTE:
When your vehicle is stopped for less than
3 seconds and the vehicle ahead begins to
move, your vehicle will start moving again
automatically. – When your vehicle is at a standstill formore than 3 seconds and the vehicle
ahead begins to accelerate, push the
RES+ switch or lightly depress the ac-
celerator pedal. The ICC system starts
to follow the vehicle ahead.
– When no vehicle is detected ahead within the driver selected distance, the
vehicle travels at the speed set by the
driver. The speed must be above
20 mph (32 km/h) to use this function. NOTE:
Even if the Forward Emergency Braking
with Pedestrian Detection setting is turned
off by the driver using the “Driver Assis-
tance” menu in the lower display, Forward
Emergency Braking with Pedestrian Detec-
tion will be automatically turned on when
ICC is used.
2. Steering Assist
The Steering Assist function controls the
steering system to help keep your vehicle
within the traveling lane.
When there is no vehicle ahead, Steering
Assist is not available at speeds under
37 mph (60 km/h).
