•The ProPILOT Assist system is only an
aid to assist the driver and is not a colli-
sion warning or avoidance device.
• The ProPILOT Assist system is for high-
way use only and is not intended for city
driving. Failure to apply the brakes or
steer the vehicle when necessary may re-
sult in a serious accident.
• Always observe posted speed limits and
do not set the speed over them.
• Never take your hands off the steering
wheel when driving. Always keep your
hands on the steering wheel and drive
your vehicle safely.
• Never unfasten your safety belt when
using ProPILOT Assist. Doing so auto-
matically cancels the ProPILOT Assist
system.
• The ProPILOT Assist system does not
react to stationary and slow moving
vehicles. •
Always drive carefully and attentively
when using the ProPILOT Assist system.
Read and understand the Owner’s
Manual thoroughly before using the
ProPILOT Assist system. To avoid seri-
ous injury or death, do not rely on the
system to prevent accidents or to control
the vehicle’s speed in emergency situa-
tions. Do not use the ProPILOT Assist
system except in appropriate road and
traffic conditions.
The ProPILOT Assist system is intended to
enhance the operation of the vehicle when
following a vehicle traveling in the same lane
and direction.
The ProPILOT Assist system uses a multi-
sensing front camera
OAinstalled behind the
windshield and a radar sensor located on the
front of the vehicle
OBto measure the dis-
tance to the vehicle ahead in the same lane
and to monitor the lane markers. If the vehicle
detects a slower moving vehicle ahead, the
system will reduce the vehicle speed so that
your vehicle follows the vehicle in front at the
selected distance. The system will also help
keep the vehicle centered in the traveling lane
when clear lane markings are detected.

2Vehicle information display
3Steering-wheel-mounted control (right)
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 selected dis-
tance 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 selected by the driver between 20 to
90 mph (30 to 144 km/h). When the ve-
hicle 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 ve-
hicle 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 standstillfor more than 3 seconds and the ve-
hicle ahead begins to accelerate,
push the RES+ switch or lightly de-
press the accelerator 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 (30 km/h) to use this func-
tion.
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).ProPILOT Assist switches
