Driving your vehicle
The ISG system is to help reduce the
fuel consumption by automatically
shutting down the engine, when the
vehicle is at a standstill (i.e. red stop
light, stop sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To Activate the ISG System
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
• The driver's seatbelt is fastened
• The driver's door and hood are
closed
• The brake vacuum pressure is
adequate
• The battery sensor is activated and
the battery is sufficiently charged
• Outside temperature is not too low
or too high
• The vehicle is driven over a con-
stant speed and stops
• The climate control system satis-
fies the conditions
• The vehicle is sufficiently warmed
up
• The incline is gradual
• The steering wheel is turned less
than 180 degrees and then the
vehicle stops
Information
The ISG system is not
activated, when the pre-
requisites to activate the
ISG system are unsatis-
fied. In this case, the ISG OFF but-
ton indicator illuminates, and the
auto stop indicator ( ) illuminates
in yellow on the instrument cluster.
• When the above indicator remains
illuminated on the instrument clus-
ter, we recommend that you have
the IGS system checked by an
authorized retailer of Genesis
Branded products.

The Battery Sensor
Deactivation
The battery sensor is deactivated,
when the battery is disconnected
from the negative pole for mainte-
nance purpose.
In this case, the ISG system is limit-
edly operated due to the battery sen-
sor deactivation. Thus, the driver
needs to take the following proce-
dures to reactivate the battery sen-
sor after disconnecting the battery.
Prerequisites to reactivate the
battery sensor
Keep the engine in the OFF status
for 4 hours, and attempt to restart the
engine 3 to 4 times for the battery-
sensor reactivation.
Pay extreme caution not to connect
any accessories (i.e. navigation and
black box) to the vehicle with the
engine in the OFF status. If not, the
battery sensor may not be reactivat-
ed.
Information
The ISG system may not operate in
the following situations.
- There is a malfunction with the ISG
system.
- The battery is weak.
- The brake vacuum pressure is low.
If this occurs, have the ISG system
checked by an authorized retailer of
Genesis Branded products.• Use only Genesis/Hyundai ISG
battery for replacement. If not,
the ISG system may not normal-
ly operate.
• Do not recharge the ISG battery
with a general battery charger. It
may damage or explode the ISG
battery.
• Do not remove the battery cap.
The battery electrolyte, which is
harmful to the human body, may
leak out.

The Forward Collision-Avoidance
Assist (FCA) system is designed to
help detect and monitor the vehicle
ahead or detect a pedestrian or
cyclist (if equipped) in the roadway
through radar signals and camera
recognition to warn the driver that a
collision is imminent, and if neces-
sary, apply emergency braking.
System Setting and Activation
System setting
• The driver can activate the FCA by
pressing Engine Start/Stop button to
the ON position and by selecting :
'User Settings →Driver Assistance
→Forward Collision-Avoidance
Assist (FCA)'
The FCA deactivates, when the driv-
er deselects the system setting.
The warning light illumi-
nates on the cluster,
when you cancel the FCA
system. The driver can
monitor the FCA ON/OFF status on
the LCD display. Also, the warning
light illuminates when the ESC
(Electronic Stability Control) is
turned off.
If the warning light remains ON when
the FCA is activated, have the sys-
tem checked by an authorized retail-
er of Genesis Branded products.
• The driver can select the initial warn-
ing activation time on the LCD dis-
play.
FORWARD COLLISION-AVOIDANCE ASSIST (FCA) SYSTEM (IF EQUIPPED)
Take the following precautions
when using the Forward Collision-
Avoidance Assist (FCA) system:
•This system is only a supple-
mental system and it is not
intended to, nor does it replace
the need for extreme care and
attention of the driver. The
sensing range and objects
detectable by the sensors are
limited. Pay attention to the
road conditions at all times.
•NEVER drive too fast in accor-
dance with the road condi-
tions or while cornering.
•Always drive cautiously to
prevent unexpected and sud-
den situations from occur-
ring. The Forward Collision-
Avoidance system may not
always stop the vehicle com-
pletely and is only intended to
help mitigate a collision that
is imminent.

• NEVER install any accessories
or stickers on the front wind-
shield, nor tint the front wind-
shield.
• NEVER locate any reflective
objects (i.e. white paper, mirror)
over the dashboard. Any light
reflection may cause a malfunc-
tion of the system.
• Pay extreme caution to keep the
camera out of water.
• NEVER disassemble the camera
assembly, nor apply any impact
on the camera assembly.
• Playing the vehicle audio sys-
tem at high volume may offset
the system warning sounds.
Information
Have the system checked by an
authorized retailer of Genesis
Branded products when:
• The windshield glass is replaced.
• The sensor cover or sensor gets
damaged or replaced.
Warning message and warning
light

with dirt, snow, or debris, the FCA
system operation may stop temporar-
ily. If this occurs, a warning message
will appear on the LCD display.
Remove any dirt, snow, or debris and
clean the radar sensor cover before
operating the FCA system.
The FCA may not properly operate in
an area (e.g. open terrain), where
any substances are not detected
after turning ON the engine.
System Malfunction

Information
• During normal cruise control opera-
tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• Before activating the cruise control
function, the system will check to
verify that the brake switch is oper-
ating normally. Depress the brake
pedal at least once after turning ON
the ignition or starting the engine.
To set Cruise Control speed
1. Press the CRUISE button on the
steering wheel to turn the system
on. The cruise indicator will illumi-
nate.
2. Accelerate to the desired speed,
which must be more than 20 mph
(30 km/h).
Information - Manual
transmission
For manual transmission vehicles, you
should depress the brake pedal at
least once to set the cruise control
after starting the engine.3. Push the toggle switch down
(SET-), and release it. The set
speed on the LCD display will illu-
minate.
4. Release the accelerator pedal.
Information
On a steep slope, the vehicle may
slightly slow down or speed up, while
driving uphill or downhill.

Driving your vehicle
• Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
• If you believe your brakes may be
wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tire tread
decreases, refer to "Tire
Replacement" in chapter 7.
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 sev-
eral 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 con-
trol resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engine
oil
Driving at higher speeds on the high-
way 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.
