RCTA SYSTEM LIMITATIONSWARNING
Listed below are the system limitations for
the RCTA system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death. •
Always check surroundings and turn to
check what is behind you before backing
up. The radar sensors detect approach-
ing (moving) vehicles. The radar sensors
cannot detect every object such as:
– Pedestrians, bicycles, motorcycles,
animals or child-operated toy ve-
hicles
– A vehicle that is passing at speeds
greater than approximately 19 mph
(30 km/h)
– A vehicle that is passing at speeds
lower than approximately 5 mph (8
km/h)
• The radar sensors may not detect ap-
proaching vehicles in certain situations:
– Illustration
OA: When a vehicle
parked next to you obstructs the
beam of the radar sensor.
– Illustration
OB: When the vehicle is
parked in an angled parking space.
– Illustration
OC: When the vehicle is
parked on inclined ground.
– Illustration
OD: When an approaching
vehicle turns into your vehicle's park-
ing lot aisle.
– Illustration
OE: When the angle
formed by your vehicle and ap-
proaching vehicle is small

•The following conditions may reduce the
ability of the radar to detect other ve-
hicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the
vehicle
• Do not attach stickers (including trans-
parent material), install accessories or
apply additional paint near the radar
sensors. These conditions may reduce
the ability of the radar to detect other
vehicles
• Excessive noise (e.g., audio system vol-
ume, open vehicle window) will interfere
with the chime sound, and it may not be
heard.
NOTE:
In the case of several vehicles approaching in
a row (Illustration 1) or in the opposite direc-
tion (Illustration 2), a chime may not be
sounded by the RCTA system after the first
vehicle passes the sensors.

•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 distance
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 dis-
tance. The system will also help keep the ve-
hicle centered in the traveling lane when clear
lane markings are detected.

• When the vehicle ahead is traveling fasterand the distance between vehicles is
increasing.
• When a vehicle cuts in near your vehicle.
The warning chime will not sound when:
• Your 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 flash when the radar
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 radar sensor may de-
tect these objects when the vehicle is driven
on winding, narrow, or hilly roads or when
the vehicle is entering or exiting a curve. In
these cases, you will have to manually con-
trol the proper distance ahead of your
vehicle.
Also, the sensor sensitivity can be affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle conditions (for example, if a vehicle is
being driven with some damage).
Acceleration when passing
When the ICC system is engaged above 43
mph and following a slower vehicle (below
ICC set speed), and the turn signal is acti-
vated to the left, the ICC system will auto-
matically start to accelerate the vehicle to
help initiate passing on the left and will begin
to reduce the distance to vehicle directly
ahead. Only the left side turn signal operates
this feature. As the driver steers the vehicle
and moves into the passing lane, if no vehicle
is detected ahead the ICC system will con-
tinue to accelerate to the ICC system set
speed. If another vehicle is detected ahead,
then the vehicle will accelerate up to the fol-
lowing speed of that vehicle. If the vehicle is
not steered into the left lane to pass, the
acceleration will stop after a short time and
regain the set following distance. Accelera-
tion can be stopped at any point by depress-
ing the brake pedal or the CANCEL switch on
the steering wheel.
WARNING
In order to reduce the risk of a collision that
may result in serious injury or death, please
be aware of the following:
• This function is only activated with the
left turn signal and will briefly accelerate
the vehicle even if a lane change is not
initiated. This can include non-passing
situations such as left side exits.
• Ensure that when passing another ve-
hicle, the adjacent lane is clear before ini-
tiating the pass. Sudden changes in traf-
fic may occur while passing- always
manually steer or brake as needed- never
solely rely on the system.
Speed Limit Assist - a feature of
ProPILOT Assist with Navi-link
(if so equipped)
When the ProPILOT Assist with Navi-link is
active and it detects a change of the speed
limit, the new speed limit is indicated and it
can be applied to the vehicle set speed auto-
matically or manually.
5-102Starting and driving

•Always check surroundings before re-
starting the vehicle.
• Always pay attention to the operation of
the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main-
tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circumstances.
• The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the ICC system under the following con-
ditions:
– On roads with heavy, high-speed
traffic or sharp curves
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.)
– When rain, snow or dirt adhere to the
bumper around the distance sensor
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes)
– On repeated uphill and downhill roads –
When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration
– Interference by other radar sources.
• Do not use the ICC system if you are
towing a trailer. The system may not de-
tect a vehicle ahead.
• In some road or traffic conditions, a ve-
hicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. Always stay alert
and avoid using the ICC system where
not recommended in this warning
section.
The ICC system will not detect the following
objects:
• Stationary or slow moving vehicles
• Pedestrians or objects in the roadway
• Oncoming vehicles in the same lane
• Motorcycles traveling offset in the travel lane
The following are some conditions in which
the radar sensor cannot properly detect a
vehicle ahead and the system may not oper-
ate properly: • When the sensor detection is reduced (con-
ditions such as rain, snow, fog, dust storms,
sandstorms, and road spray from other
vehicles)
• Driving on a steep downhill slope or roads with sharp curves
• Driving on a bumpy road surface, such as an uneven dirt road
• If dirt, ice, snow or other material is cover- ing the radar sensor area
• A complicated-shaped vehicle such as a car carrier trailer or flatbed truck/trailer is near
the vehicle ahead.
• Interference by other radar sources
• When your vehicle is towing a trailer, etc.
• When excessively heavy baggage is loaded in the rear seat or cargo area of your
vehicle.
The ICC system is designed to automatically
check the radar sensor’s operation within the
limitations of the system.
The detection zone of the radar sensor is
limited. A vehicle ahead must be in the detec-
tion zone for the ICC system to maintain the
selected distance from the vehicle ahead. A
vehicle ahead may move outside of the de-
tection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
