Predictive shift feature proactively
upshifts or downshifts the gear based on
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.
Predictive shift Operating
Conditions
Predictive shift operates when it is in
the ready state, and a specific situation
is detected while driving. Details
on prerequisites for activation and
operations are as follows.

Limitations of the System
The predictive shift may have limited
operation in the following situations

[If you do not take the route guided in
the navigation, predictive shift may
not operate properly since the system
operates according to the navigated
route. Predictive shift will operate
properly again once the navigation
sets a new route.

[The navigation may reflect the real
time traffic condition and change the
route. If so, the predictive shift may
not correspond temporarily to the
current driving condition.

[If the destination is not set on the
navigation, predictive shift operates
according to the route which is most
likely to be taken. When driving
through roads such as a branch road,
predictive shift may not correspond to
the current driving condition until the
navigation sets a new route.

[While using the navigation app
through smart phone linked functions
such as Android Auto or Apple
CarPlay, predictive shift operates as
when the destination is not set in the
vehicle’s navigation.

[Predictive shift may not operate
properly in the following situations.
-Navigation system is not completely
booted.
-Real time GPS or map data has
errors, or the map data is not up to
date.
Checking Operation on the
Instrument Cluster
The operating condition of predictive
shift can be checked from the icons and
messages displayed on the instrument
cluster. If there are multiple conditions
detected, every related icon illuminates
but only the most important message
is displayed. The images and colors
of the messages may differ from the
description depending on the cluster
type.
CAUTION
Always be aware of the traffic and
road condition ahead. Checking the
instrument cluster while driving
may cause an accident.

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.
