[Comfort or Sport is selected for
driving mode

[The driver uses the paddle shifter

[Smart Cruise Control is activated (Set
speed appears on the cluster)

[The vehicle’s speed exceeds 30~100
mph (50~160 km/h) range

[The road gradient is under -5% or over
+5%

[If the distance between the vehicle
ahead is too close or the relative
speed changes momentarily in Smart
mode

[If lane change is predicated in Smart
mode (for example, the turn signal is
turned ON or a LKA warning appears
due to steering wheel control, etc.)
Information
It is recommended to turn off the
Coasting function if you are driving under
frequently stop-and-go condition. Change
the drive mode to Comfort or Sport or
deselect Coasting from the infotainment
system screen.
NOTICE

[If the accelerator pedal is pressed
quickly for accelerating with the

acceleration may occur after the
engagement of the clutch inside the
transmission. In turn, the driver may
continue to feel acceleration even
after the system is turned off.

[Driving with the Coasting function
off may be required in some cases
since the engine brake is not applied
while the Coasting function is
operating.

[Operating the infotainment system
screen to activate or deactivate
the Coasting function while driving
may be dangerous as the driver’s
attention is dispersed.

the data detected from the navigation,
front radar sensor, and camera.
CAUTION
Predictive shift is a convenience
feature. Regardless of its operation,
the driver must pay attention to
the road condition and abide traffic
laws. The vehicle manufacturer
does not take any responsibility for
traffic law violation and accidents.

How Predictive Shift Operates
Predictive shift operates according to the
detected conditions.
Predictive shift in curve
If there is a curve ahead, the gear is
downshifted in advance to engage the
engine brake automatically. After passing
the curve, it will help the vehicle to
reaccelerate.
-If you drive smoothly through a curve,
or if the curve is gradual, predictive
shift does not operate.
-Predictive shift may operate if there is
a sharp curve, or the vehicle speed is
high when entering a highway ramp or
turning left or right on a crossroad.
Predictive shift to maintain speed
during downhill coasting
When coasting on a downhill, the engine
brake is automatically engaged to help
maintain the vehicle speed.
-If the slope is gentle or short,
predictive shift does not operate.
-If the downhill slope is steep, the
engine brake may be strongly
engaged to maintain speed.
-Depressing the brake or accelerator
pedal while predictive shift is being
activated will temporarily disable the
function.
CAUTION
Predictive shift to maintain speed
during downhill coasting is only to
assist the driver to drive safely on
a downhill. It does not accelerate
or decelerate the vehicle. If
acceleration or deceleration is
required, depress the pedal to
manually adjust the speed.

6-60
Driving Your Vehicle
Predictive shift in roundabout
If there is a roundabout ahead, the
predictive shift downshifts the gear
before entering the roundabout to assist
the driver to go through the roundabout
smoothly and reaccelerate the vehicle.
Predictive shift to accelerate when
entering highways (Interchange/Junction)
When entering the main road of
highways, the drive mode is temporarily
changed to SMART SPORT at the
interchange or junction to assist the
vehicle to accelerate easily.
-It also operates when entering an
expressway.
-While the SMART SPORT mode is
on, the red ‘SMART’ message will
illuminate on the instrument cluster.
-The drive mode will revert back to
SMART ECO or SMART COMFORT
when the vehicle has completely
entered the highways.
-Predictive shift operates only when
the vehicle is accelerated sufficiently
at the highways interchange or
junction to enter the main road. It
does not operate if the vehicle speed
is low.
-When entering the highways ramp
with the vehicle in SMART ECO mode,
the drive mode will automatically
change to SMART COMFORT. The
white ‘SMART’ message will illuminate
on the cluster.
-When predictive shift is operating, the
acceleration performance is equal to
that of when SPORT mode is selected
by pressing the drive mode button.
Predictive shift when approaching a
vehicle ahead
If the speed of the vehicle ahead is low
and the distance is getting closer, the
engine brake is engaged automatically to
assist in deceleration.
-When the vehicle reaches an
appropriate distance and the speed is
equal to the vehicle ahead, predictive
shift will be finished.
-If the brake or accelerator pedal
is depressed while predictive shift
is operating, the function will be
temporarily disabled.
-If there is a large difference of speed
from the vehicle ahead, the engine
brake may be engaged greatly to
obtain appropriate vehicle-to-vehicle
distance.
CAUTION
‘Predictive Shift when Approaching
to Vehicle Ahead’ is a function to
assist deceleration by detecting
the speed difference with the
vehicle ahead and does not directly
prevent collision. If the vehicle
ahead abruptly decelerates and
the distance rapidly decreases, the
driver must depress the brake pedal
to decelerate.

ECO, COMFORT, SPORT Mode
Features
ECO mode (if equipped)
ECO mode helps improve fuel
efficiency for eco-friendly
driving.
Fuel efficiency varies according
to the driver's driving habit and
road condition.

[When ECO mode is selected, the
ECO indicator will illuminate on the
instrument cluster.

[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.
-Engine noise may be louder at some
automatic transmission shifts as
down-shift requires pressing down
more on the accelerator.
The above situations are normal
conditions when ECO mode is activated
to help improve fuel efficiency.
COMFORT mode
COMFORT mode provides smooth
driving and comfortable riding.
SPORT mode
SPORT mode provides sporty
but firm riding.
In SPORT mode, the fuel
efficiency may decrease.

[When SPORT mode is selected, the
SPORT indicator will illuminate on the
instrument cluster.

[Whenever the engine is restarted,
the drive mode will revert back to
COMFORT mode. If SPORT mode is
desired, re-select SPORT mode.

[When SPORT mode is activated:
-The engine RPM will tend to remain
raised over a certain length of time
even after releasing the accelerator
-Upshifts are delayed when
accelerating
NOTICE
In the SPORT mode, the fuel efficiency
may decrease.

CUSTOM Mode Features
SMART mode
SMART mode selects the proper driving
mode among SMART ECO, SMART
COMFORT and SMART SPORT by judging
the driver's driving habits (for example,
mild or dynamic) from the brake pedal
depression or the steering wheel
operation.
Various driving situations, which you may
encounter in SMART mode

[The driving mode automatically
changes to ECO mode after a certain
period of time, when you gently
depress the accelerator pedal (Your
driving is categorized to be mild.).

[The driving mode automatically
changes from SMART ECO mode
to SMART COMFORT mode after a
certain period of time, when you
sharply or repetitively depress the
accelerator pedal.

[The driving mode automatically
changes to SMART COMFORT mode
with the same driving patterns, when
the vehicle starts to drive on an
upward slope of a certain angle. The
driving mode automatically returns to
SMART ECO mode, when the vehicle
enters a leveled road.

[The driving mode automatically
changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situations,
the driving mode sets to be either
in SMART ECO mode or in SMART
COMFORT mode.
[The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating or decelerating
and increases the engine brake
performance.
For general description of SMART ECO,
SMART COMFORT, and SMART SPORT
modes, refer to “ECO, COMFORT, SPORT
mode features”.

Limitation of SMART mode
SMART may be limited in following
situations. ECO, COMFORT, SPORT mode
features

[The driver is using the paddle shifter
to manually shift gear. (The system
prioritizes the driver’s manual shifting)

[Smart Cruise Control is activated.

[The transmission oil temperature is
either extremely low or extremely
high.
Information

[When you mildly drive the vehicle
in SMART mode, the driving mode
changes to ECO mode to improve fuel
efficiency. However, the actual fuel
efficiency may differ depending on your
driving situations such as slope angle,
and vehicle speed.

[When you dynamically drive the
vehicle in SMART mode by abruptly
decelerating or sharply curving, the
driving mode changes to SPORT mode.
However, it may adversely affect fuel
economy.
CHAUFFEUR mode
CHAUFFEUR mode controls the
suspension, engine, transmission, and
steering wheel to provide comfort driving
experience to rear seat passengers.
MY DRIVE MODE

SPECIAL DRIVING CONDITIONS
Hazardous Driving Conditions
When hazardous driving elements
are encountered such as water, snow,
ice, mud and sand, take the following
precautions:

[Drive cautiously and maintain 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
unnecessary wheel spin.

[Put sand, rock salt, tire chains or other
non-slip materials under the wheels to
provide additional traction while the
vehicle becomes stuck in ice, snow,
or mud.
WARNING
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
downshifting on slippery surfaces.
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 forward 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 accelerator 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.
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 vehicle, the
vehicle can overheat quickly, possibly
causing an engine compartment fire or
other damage. Try to avoid spinning 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).

6-67
06
Information
The ESC system must be turned OFF
before rocking the vehicle.
NOTICE
If you are still stuck after rocking the
vehicle a few times, have the vehicle
pulled out by a tow vehicle to avoid
engine overheating, possible damage to
the transmission, and tire damage. See
“Towing” section in chapter 8.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration.
Driving at Night
Night driving presents more hazards than
driving in the daylight. Here are some
important tips to remember:

[Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.

[Adjust your mirrors to reduce the glare
from other drivers’ headlights.

[Keep your headlights clean and
properly aimed. Dirty or improperly
aimed headlights will make it much
more difficult to see at night.

[Avoid staring directly at the headlights
of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to
readjust to the darkness.

6-68
Driving Your Vehicle
Driving in the Rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or on
slick pavement:

[Slow down and allow extra following
distance. A heavy rainfall makes
it harder to see and increases the
distance needed to stop your vehicle.

[Turn OFF your Smart Cruise Control

[Replace your windshield wiper blades
when they show signs of streaking or
missing areas on the windshield.

[Be sure your tires have enough tread.
If your tires do not have enough depth
of tire tread, making a quick stop on
wet pavement can cause a skid and
possibly lead to an accident. See “Tire
Tread” section in chapter 9.

[Turn on your headlights to make it
easier for others to see you.

[Driving too fast through large puddles
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 driving 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 increases as the
depth of tire tread decreases, refer to
“Tire Tread” section in chapter 9.
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 fail the
braking operation.
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.
