Driving your vehicle
ECO mode
When ECO mode is
selected by pressing the
DRIVE MODE button, the
ECO indicator will illumi-
nate on the instrument
cluster.
• If the vehicle is set to ECO mode,
when the engine is turned OFF
and restarted the drive mode set-
ting will remain in ECO mode.
Information
Fuel efficiency depends on the driver's
driving habit and road condition.
When ECO mode is activated:
• The acceleration response may be
slightly reduced if the accelerator
pedal is depressed moderately.
• The air conditioner performance
may be limited.
• The shift pattern of the automatic
transmission may change.
• The engine noise may be louder at
some automatic transmission
shifts as down-shift requires press-
ing down more on the accelerator.
The above situations are normal
conditions when ECO mode is acti-
vated to help improve fuel efficiency.
Limitation of ECO mode operation:
If the following conditions occur while
ECO mode is operating, the system
operation is limited even though
there is no change in the ECO indi-
cator.
• When the coolant temperature is
low:
The system will be limited until
engine performance becomes nor-
mal.
• When driving up a hill:
The system will be limited to gain
power when driving uphill because
engine torque is restricted.
• When driving the vehicle in manual
shift mode using the paddle shifter.
The system will be limited accord-
ing to the shift location.
CUSTOM mode
When CUSTOM mode is
selected by pressing the
DRIVE MODE button, the
CUSTOM mode indicator
will illuminate on the
instrument cluster.
• In CUSTOM mode, the driver can
select separate modes and combine
them in the AVN system screen.

When certain conditions are met, the
engine is automatically decoupled
from the transmission while the shift
lever is remained in D (Drive). In this
Coasting mode, the engine stays at
idling speed to reduce fuel consump-
tion and increase coasting distance.
Coasting Setting
The Coasting function must be
turned ON from the Settings menu in
the AVN system screen. Select:
- Setup →Vehicle Settings →Drive
Mode →Coasting
For detailed information, scan the
QR code in a separately supplied
simple manual.
When Coasting is turned ON and the
conditions are met, the function
operates with a "Coasting" message
illuminated at the top center of the
instrument cluster.
• If the accelerator pedal is
pressed quickly for accelerating
with the Coasting function in
operation, acceleration may
occur after the engagement of
the clutch inside the transmis-
sion. In turn, the driver may con-
tinue to feel acceleration even
after the system is turned off.
• Driving with the Coasting func-
tion off may be required in some
cases since the engine brake is
not applied while the Coasting
function is in operation.
• Operating the AVN system
screen to activate or deactivate
the Coasting function while driv-
ing may be dangerous as the dri-
ver's attention is dispersed.
Coasting Operating
Conditions
The Coasting function will operate
when the accelerator pedal is
depressed and released under the
following conditions.
• The driving mode is ECO mode.
• SMART is selected for Engine/
Transmission in CUSTOM mode
from the AVN system screen and
driver acceleration is SMART ECO
• ECO is selected for Engine/
Transmission in CUSTOM mode
from the AVN system screen
• The shift lever is in D (Drive)
• The Smart Cruise Control button is
OFF
• The accelerator or brake pedal is
not depressed
• The vehicle's speed is within
35–100 mph (55–160 km/h) range
• The road gradient is within -5~+5%
range
• In SMART mode, if the distance
between the vehicle ahead and the
relative speed is within a certain
range
Information
• If the front radar for smart cruise
control system cannot operate nor-
mally, the inter-vehicle distance and
relative speed condition are auto-
matically ignored.
• The Coasting function works after
the engine is turned on, the trans-
mission is warmed up, and the
engine sensor self-diagnosis is com-
pleted after starting.
• Depending on the driving situation,
Coasting operation may be tem-
porarily delayed even if the above
conditions are met.

Driving your vehicle
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
below suggestions:
• Drive cautiously and keep a longer
braking distance.
• Avoid abrupt braking or steering.
• When your vehicle is stuck in snow,
mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
• Put sand, rock salt, tire chains or
other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
stuck in ice, snow, or mud.
Rocking the Vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-
tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.
SPECIAL DRIVING CONDITIONS
Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING
If the vehicle is stuck and
excessive wheel spin occurs,
the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehi-
cle, the vehicle can overheat
quickly, possibly causing an
engine compartment fire or
other damage. Try to avoid spin-
ning the wheels as much as
possible to prevent overheating
of either the tires or the engine.
DO NOT allow the vehicle to
spin the wheels above 35 mph
(56 km/h).

What to do in an emergency
9. Connect the second jumper cable
to the black, negative (-) battery/
chassis ground of the assisting
vehicle (3).
10. Connect the other end of the sec-
ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals
or the correct ground. Do not
lean over the battery when mak-
ing connections.
11. Start the engine of the assisting
vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
12. Keep your vehicle operating for at
least 30 minutes at idle or driving
to assure your battery receives
enough charge to be able to start
on its own after the vehicle is
shut off. A complete dead battery
may require as long as 60 min-
utes runtime to fully recharge it. If
vehicle is run for less, the battery
may not restart. If you continue to
have problem, have your author-
ized retailer of Genesis Branded
products test the battery.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized retailer of Genesis
Branded products.Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the
jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper
cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the
jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1).

Always follow these emergency tow-
ing precautions:
• Place the shift lever in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more
force than normal as you will have
reduced braking performance.
• More steering effort will be
required because the power steer-
ing system will be disabled.
• Use a vehicle heavier than your
own to tow your vehicle.
• The drivers of both vehicles should
communicate with each other fre-
quently.
• Before emergency towing, check
that the hook is not broken or dam-
aged.
• Fasten the towing cable or chain
securely to the hook.
• Do not jerk the hook. Apply steady
and even force.• Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inch
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
• Drive carefully so the towing cable
or chain remains tight during tow-
ing.
• Before towing, check the automat-
ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.OHI068024
The driver must be in the vehi-
cle for steering and braking
operations when the vehicle is
being towed. Passengers other
than the driver must not be in
the vehicle.
CAUTION

What to do in an emergency
Accelerate or decelerate the vehi-
cle in a slow and gradual manner
while maintaining tension on the
tow rope or chain to start or drive
the vehicle, otherwise tow hooks
and the vehicle may be damaged.
To avoid damage to your vehicle
and vehicle components when
towing:
• Always pull straight ahead when
using the towing hooks. Do not
pull from the side or at a vertical
angle.
• Do not use the towing hooks to
pull a vehicle out of mud, sand
or other conditions from which
the vehicle cannot be driven out
under its own power.
• Limit the vehicle speed to
10 mph (15 km/h) and drive less
than 1 mile (1.5 km) when towing
to avoid serious damage to the
automatic transmission.
