Coasting Release Conditions
The Coasting function will be
automatically released when the
following conditions are met.

[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
Coasting function in operation,
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.

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.

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”.

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.

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 or to
install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to carry
include tire chains, tow straps or chains,
a flashlight, emergency flares, sand, a
shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket,
etc.
Summer tires

[Summer tires are used to maximize
the driving performance on dry roads.

[If the temperature is below 45°F or
you are driving on snowy or icy roads,
the summer tires lose their brake
performance and traction as the tire
grip weakens significantly.

[If the temperature is below 45°F or
you are driving on snowy or icy roads,
mount snow tires or all-season tires
of the same size with your vehicle's
standard tire for safe driving. Both
snow and all-season tires have M+S
markings.

[When using the M+S tires, use tires
with the same tread produced by the
same manufacturer for safe driving.

[When driving with the M+S tires with
the lower maximum allowable speed
than that of the vehicle's standard
summer tire, be careful not to exceed
the speed allowed for the M+S tires.

Driving Your Vehicle
NOTICE
If you drive without disabling the
Rear Wheel Steering system in the
infotainment system after installing
snow chains, the snow chains can
damage your vehicle’s body or chassis
parts. When you hear the snow chain
hitting the vehicle, stop the vehicle and
check whether the snow chains are
installed properly and whether the Rear
Wheel Steering system is disabled.
Information

[Install AutoSock® (fabric snow chain)
only in pairs and on the rear tires.
It should be noted that installing
AutoSock (fabric snow chain) on the
tires will provide a greater driving
force, but will not prevent side skids.

[Do not install studded tires without
first checking local, state and municipal
regulations for possible restrictions
against their use.
Chain Installation
When installing AutoSock® (fabric
snow chain), follow the manufacturer's
instructions and mount them as tightly
as possible. Drive slowly (less than 20
mph (30 km/h)) with AutoSock® installed.
If you hear the fabric snow chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the AutoSock® as soon as you begin
driving on cleared roads.
When mounting AutoSock®, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available).
Always place the vehicle in P (Park),
apply the parking brake and turn off the
engine before installing tire chains.
NOTICE
When using AutoSock® (fabric snow
chain):

[Wrong size fabric snow chains or
improperly installed fabric snow
chains can damage your vehicle's
brake lines, suspension, body and
wheels.

[If you hear noise caused by fabric
snow chains contacting the body,
retighten the fabric snow chains to
prevent contact with the vehicle
body.

[To prevent body damage, retighten
the fabric snow chains after driving
0.3~0.6 miles (0.5~1.0 km).

Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures
anticipated during the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in chapter 9. The
battery charging level can be checked by
an authorized retailer of Genesis Branded
products or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized retailer of Genesis Branded
products.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. If necessary, replace them.
Also check all ignition wirings and
components for any cracks, wear-out,
and damage.
To prevent locks from freezing
To prevent the locks from being frozen,
spray approved de-icing fluid or glycerin
into key holes. When a lock opening is
already covered with ice, spray approved
de-icing fluid over the ice to remove it.
When an internal part of a lock freezes,
try to thaw it with a heated key. Carefully
use the heated key to avoid an injury.
Use approved window washer anti-
freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized retailer of
Genesis Branded products, and most
vehicle accessory outlets. Do not use
engine coolant or other types of anti-
freeze solution, to prevent any damage
to the vehicle paint.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the gear in P (Park). Also,
block the rear wheels in advance, so the
vehicle may not roll. Then, release the
parking brake.
