6-52
Prerequisite for activation
FCA gets ready to be activated, when
‘Active Assist’ or ‘Warning Only’ under
Forward Safety is selected in the cluster
LCD display, and when the following
prerequisites are satisfied.
- ESC (Electronic Stability Control) is on.
- Vehicle speed is over 10 km/h (6 mph).
(FCA is only activated within a certain
speed range.)
- The system detects a pedestrian, cyclist or a vehicle in front, which may
collide with your vehicle. However,
FCA may not be activated or may only
sound a warning alarm depending on
the driving or vehicle conditions.
FCA may not operate properly according
to the frontal situation, condition of the
vehicle, the direction of pedestrian or
cyclist or speed. If you select "Warning
Only", only warnings occur.
WARNING
To avoid driver distractions, do not
attempt to set or cancel FCA while
driving the vehicle. Always completely
stop the vehicle at a safe place before
setting or canceling the system.
FCA automatically activates upon
placing the ignition switch to the ON
position. The driver can deactivate FCA
by canceling the system setting on the
cluster LCD display or infotainment
system display (if equipped).
FCA automatically deactivates upon
canceling ESC (Electronic Stability
Control). When ESC is canceled, FCA
cannot be activated in the LCD display
or infotainment system display (if
equipped). In this situation, the FCA
warning light will illuminate which is normal.
FCA Warning Message and Brake
Control
FCA produces warning messages,
warning alarms, and emergency braking
based on the level of risk of a frontal
collision, such as when a vehicle ahead
suddenly brakes, or the system detects
that a collision with a pedestrian or
cyclist is imminent.
Collision warning (First warning)
ODN8H069201L
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decelerate
the vehicle.

•
Your vehicle speed may decelerate
moderately.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is between 10 km/h (6 mph)
and 180 km/h (112 mph). Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) and 85 km/h (53
mph). Maximum vehicle speed may
decrease depending on the condition
of the pedestrian or cyclist ahead and
surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake. Emergency braking (Second
warning)
ODN8H069202L
This warning message appears on the
LCD display with a warning chime.
Additionally, some vehicle system
intervention occurs by the engine
management system to help decelerate
the vehicle. • FCA system limitedly controls the
brakes to preemptively mitigate
impact in a collision. The brake control
is maximized just before a collision.
• If FCA detects a vehicle in front, the
system operates when your vehicle
speed is above 10 km/h (6 mph) and
75 km/h (47 mph) or under. Maximum
vehicle speed may decrease
depending on the condition of the
vehicle ahead and surroundings.
• If FCA detects a pedestrian or cyclist
in front, the system operates when
your vehicle speed is between 10
km/h (6 mph) or above and under 65
km/h (40 mph). Maximum vehicle
speed may decrease depending on
the condition of the pedestrian or
cyclist ahead or surroundings.
• If you select ‘Warning Only’ for the
system setting, FCA system activates
and produces only warning alarms
in accordance with the collision risk
levels. You should control the brake
directly because FCA system will not
control the brake.

•
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.

When using Smart Cruise Control take
the following precautions: • If an emergency stop is necessary,
you must apply the brakes. The
vehicle cannot be stopped at every
emergency situation by using Smart
Cruise Control system.
• Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too close during a high-speed driving, a
serious collision may result.
• Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.
• Smart Cruise Control system cannot
recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.
• Vehicles moving in front of you with
a frequent lane change may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.
• Always be aware of the selected
speed and vehicle to vehicle
distance. The driver should not solely
rely on the system but always pay
attention to driving conditions and
control your vehicle speed.
• Smart Cruise Control system may not
recognize complex driving situations
so always pay attention to driving
conditions and control your vehicle speed.• Smart Cruise Control system may
recognize a pedestrian, bicycle,
motorcycle, etc. as a vehicle. Always,
look ahead cautiously to prevent
unexpected and sudden situations
from occurring.
• Turn off Smart Cruise Control system
when the vehicle is being towed.
NOTICE
Smart Cruise Control system may not
operate temporarily due to: • Electrical interference
• Modifying the suspension
• Differences of tire abrasion or tire
pressure
• Installing different type of tires
The brake control using Smart Cruise
Control system may make a sound.

The severe weather conditions of winter
quickly wear out tires and cause other
problems. To minimize winter driving
problems, you should take the following
suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle in
front of you.
Apply the brakes gently. Speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially
very hazardous practices. During
deceleration, use engine braking to the
fullest extent. Sudden brake applications
on snowy or icy roads may cause the
vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tow straps or chains, a flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
WARNING
Snow tires should be equivalent in size
and type to the vehicle’s standard tires.
Otherwise, the safety and handling of
your vehicle may be adversely affected.
If you mount snow tires on your vehicle,
make sure to use radial tires of the same
size and load range as the original tires.
Mount snow tires on all four wheels
to balance your vehicle’s handling in
all weather conditions. The traction
provided by snow tires on dry roads
may not be as high as your vehicle's
original equipment tires. Check with
the tire dealer for maximum speed
recommendations.
Information
Do not install studded tires without first checking local, country and municipal
regulations for possible restrictions against
their use.

Emergency Situations
7-6
If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift button in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do
not open the hood until the coolant
has stopped running or the steaming
has stopped. If there is no visible
loss of engine coolant and no steam,
leave the engine running and check
to be sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury.
4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.
If the engIne overheats

Emergency Situations
7-12
Each wheel is equipped with a tire
pressure sensor mounted inside the tire
behind the valve stem (except for the
spare tire). You must use TPMS specific
wheels. It is recommended that you
always have your tires serviced by an
authorized HYUNDAI dealer.
You may not be able to identify a tire
with low pressure by simply looking at it.
Always use a good quality tire pressure
gauge to measure the tire’s inflation
pressure. Please note that a tire that is
hot (from being driven) will have a higher
pressure measurement than a tire that is cold.
A cold tire means the vehicle has been
sitting for 3 hours and driven for less
Than 1.6 km (1 mile) in that 3 hour period.
Allow the tire to cool before measuring
the inflation pressure. Always be sure
the tire is cold before inflating to the
recommended pressure.
WARNING
• The TPMS cannot alert you to severe
and sudden tire damage caused by
external factors such as nails or road debris.
• If you feel any vehicle instability,
immediately take your foot off
the accelerator, apply the brakes
gradually with light force, and slowly
move to a safe position off the road.
WARNING
Tampering with, modifying, or disabling
the Tire Pressure Monitoring System
(TPMS) components may interfere
with the system’s ability to warn the
driver of low tire pressure conditions
and/or TPMS malfunctions. Tampering
with, modifying, or disabling the Tire
Pressure Monitoring System (TPMS)
components may void the warranty for
that portion of the vehicle.
