WARNING
Failure to follow the warnings and instruc-
tions for proper use of the ProPILOT Assist
system could result in serious injury or
death.
∙ ProPILOT Assist is not a self-driving sys-tem. Within the limits of its capabilities,
as described in this manual, it helps the
driver with certain driving activities.
∙ The ProPILOT Assist system is not a re- placement for proper driving procedures
and is not designed to correct careless,
inattentive or absent-minded driving.
ProPILOT Assist will not always steer
the vehicle to keep it in the lane. The Pro-
PILOT Assist system is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
∙ There are limitations to the ProPILOT Assist system capability. The ProPILOT
Assist system does not function in all
driving, traffic, weather, and road condi-
tions. It is the driver’s responsibility to
stay alert, drive safely, keep the vehicle in
the traveling lane, and be in control of the
vehicle at all times. ∙ 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.
∙ The ProPILOT Assist system does not re- act 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 Pro-
PILOT Assist system. To avoid serious in-
jury or death, do not rely on the system to
prevent accidents or to control the vehi-
cle’s speed in emergency situations. Do
not use the ProPILOT Assist system ex-
cept 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
Ainstalled behind the
windshield and a radar sensor located on the
front of the vehicle
Bto 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.

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
Page 369 of 573

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).

MODE ON
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
To choose the conventional (fixed speed)
cruise control mode, push and hold the Pro-
PILOT Assist switch for longer than approxi-
mately 1.5 seconds. For additional informa-
tion, refer to “Conventional (fixed speed)
cruise control mode” in this section.

How to change the set vehicle
speed
The set vehicle speed can be adjusted.
To change to a faster cruising speed:
∙ Push and hold the RES+ switch. The set vehicle speed increases by approximately
5 mph (5 km/h).
∙ Push, then quickly release, the RES+ switch. Each time you do this, the set
speed increases by approximately 1 mph
(1 km/h). To change to a slower cruising speed:
∙ Push and hold the SET- switch. The set vehicle speed decreases by approxi-
mately 5 mph (5 km/h).
∙ Push, then quickly release, the SET- switch. Each time you do this, the set
speed decreases by approximately 1 mph
(1 km/h).
How to momentarily accelerate or
decelerate
∙ Depress the accelerator pedal when ac-celeration is required. Release the accel-
erator pedal to resume the previously set
vehicle speed.
∙ Depress the brake pedal when decelera- tion is required. Control by the ProPILOT
Assist system is canceled. Push the RES+
switch to resume the previously set ve-
hicle speed.
LSD2948

WARNING
When the accelerator pedal is depressed
and you are approaching the vehicle ahead,
the ICC system will neither control the
brake nor warn the driver with the chime
and display. The driver must manually con-
trol the vehicle speed to maintain a safe
distance to the vehicle ahead. Failure to do
so could result in severe personal injury or
death.
NOTE:
When you accelerate by depressing the ac-
celerator pedal or decelerate by pushing the
SET- switch and the vehicle travels faster
than the speed set by the driver, the set
speed vehicle indicator will blink.
How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time.
Each time the DISTANCE switch
Ais
pushed, the set distance will change to long,
middle, short and back to long again in that
sequence.

∙ The distance to the vehicle ahead changes automatically according to the
vehicle speed. The higher the vehicle
speed, the longer the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine is
started, the initial setting becomes
“long.”)
