The Idle Stop and Go (ISG) system
automatically and temporarily shuts
down the engine when the vehicle
is stopped and idling to improve fuel
efficiency and reduce exhaust gas
emissions. (i.e. red stop light, stop sign,
and traffic jam).
The engine is automatically started upon
satisfying the starting conditions.
The ISG system is always active, when
the engine is running.
Information
When the engine is automatically started
by the ISG system, some warning
lights (i.e. ABS, ESC, ESC OFF, EPS,
and parking brake warning light) may
illuminate for a few seconds due to the

Brake operation
• In an urgent situation, the braking
system enters into the ready status for
prompt reaction against the driver’s
depressing the brake pedal.
• FCA provides additional braking
power for optimum braking
performance, when the driver
depresses the brake pedal.
• The braking control is automatically
deactivated, when the driver sharply
depresses the accelerator pedal, or
when the driver abruptly operates the
steering wheel.
• FCA brake control is automatically
canceled, when risk factors disappear.
CAUTION
• The driver should always use
extreme caution while operating
the vehicle, whether or not there is a
warning message or alarm from FCA
system.
• After the brake control is activated,
the driver must immediately depress
the brake pedal and check the
surroundings. The brake activation
by the system lasts for about 2
seconds.
• If any other warning sound such as
seat belt warning chime is already
generated, Forward Collision-
Avoidance Assist system warning
may not sound.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing the system warning
sounds.
WARNING
The braking control cannot completely
stop the vehicle nor avoid all
collisions. The driver should hold the
responsibility to safely drive and control
the vehicle.
WARNING
The FCA system logic operates within
certain parameters, such as the
distance from the vehicle, pedestrian or
cyclist (if equipped) ahead, the speed
of the vehicle ahead, and the driver’s
vehicle speed. Certain conditions
such as inclement weather and road
conditions may affect the operation of
FCA system.
WARNING
Never deliberately drive dangerously to
activate the system.
Information
Exceptional operation of the braking assist
system
• The vehicle drives on a slope or curve.
• The vehicle drives by a pedestrian or
cyclist at the crossroads, traffic signals
or structure.
• The vehicle drives through a tunnel or
near a railroad.
• The vehicle drives where steam, smoke
or shadow is on the road.
• The vehicle drives the road tree planted
or streetlamps installed.
• There is interference by
electromagnetic waves or electric noise.
While Driving

• If the vehicle in front stops suddenly,
you may have less control of the
brake system. Therefore, always keep
a safe distance between your vehicle
and the vehicle in front of you.
• FCA system may activate during
braking and the vehicle may stop
suddenly shifting loose objects
toward the passengers. Always keep
loose objects secured and fasten the
seat belt.
• FCA system may not activate if the
driver applies the brake pedal to
avoid collision.
• The brake control may be
insufficient, possibly causing a
collision, if a vehicle in front abruptly
stops. Always pay extreme caution.
• Occupants may get injured, if
the vehicle abruptly stops by the
activated FCA system. Pay extreme
caution.
• FCA system operates only when the
system detect vehicles, pedestrian or
cyclist in front of the vehicle.
• FCA system may not activate
according to road conditions,
inclement weather, driving
conditions or traffic conditions.
• FCA system may not work for all
vehicles, passengers or cyclists. WARNING
• FCA system does not operate when
the vehicle is in reverse.
• FCA system is not designed to detect
other objects on the road such as
animals.
• FCA system does not detect vehicles
in the opposite lane.
• FCA system does not detect cross
traffic vehicles that are approaching.
• FCA system cannot detect vehicles
that are stopped vertically to your
vehicle at a intersection or dead end
street.
• FCA system cannot detect the cross
traffic cyclist that are approaching.
In these cases, you must maintain a
safe braking distance, and if necessary,
depress the brake pedal to reduce the
driving speed in order to maintain a
safe distance or to stop the vehicle.
Limitations of the System
Forward Collision avoidance assist
system is designed to monitor the
vehicle ahead or a pedestrian or cyclist
in the roadway through radar signals
and camera recognition to warn the
driver that a collision is imminent, and if
necessary, apply emergency braking.
In certain situations, the radar sensor
or the camera may not be able to
detect the vehicle, pedestrian or cyclist
ahead. In these cases, FCA system may
not operate normally. The driver must
pay careful attention in the following
situations where FCA operation may be
limited.

Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or adversely
affect vehicle handling. This could lead
to sudden tire failure that may cause
loss of vehicle control resulting in an
accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
