Virtual Engine Sound System
The Virtual Engine Sound System
generates engine sound for pedestrians
to hear vehicle sound because there is
no sound while the Electric Vehicle (EV)
is operating. • If the vehicle is in the ready (
)
mode and the gear is not in P (Park),
the VESS will be operated.
• When the gear is shifted to R
(Reverse), an additional warning
sound will be heard.
CAUTION
• The vehicle is much quieter while
driving than a conventional gasoline-
powered vehicle. Be aware of your
surroundings and always drive safely.
• After you park the vehicle or while
you are waiting at a traffic light,
check whether there are children or
obstacles around the vehicle.
• Check if there is something behind
the vehicle when driving in reverse.
Pedestrians may not hear the sound
of the vehicle.
Distance to Empty
ONE1Q011049E
The distance to empty is displayed
differently according to the selected
drive mode in the Drive Mode Integrated
Control System.
For more information, refer to “Drive
Mode Integrated Control System” in
chapter 6.
When destination is not set • On average, a vehicle can drive about
199 miles (320 km) (Standard type) /
249 miles (400 km) (Extended type).
• Under certain circumstances where
the air conditioner/heater is ON,
the distance to empty is impacted,
resulting in a possible distance range
from 106 ~ 286 miles (170 ~ 460 km)
(Standard type) / 130 ~ 354 miles
(210 ~ 570 km) (Extended type).
When using the heater during cold
weather or driving at high speed, the
high voltage battery consumes a lot
more electricity. This may reduce the
distance to empty significantly.
• After ‘0 km’ has been displayed,
the vehicle can drive an additional
2~5 miles (3~8 km) depending on
driving speed, heater/air conditioner,
weather, driving style, and other
factors.

Foreword / Electric Vehicle System Overview
1-52
•
Distance to empty that is displayed
on the instrument cluster after
completing a recharge may vary
significantly depending on previous
operating patterns.
When previous driving patterns
include high speed driving, resulting
in the high voltage battery using more
electricity than usual, the estimated
distance to empty is reduced. When
the high voltage battery uses little
electricity in ECO mode, the estimated
distance to empty increases.
• Distance to empty may depend on
many factors such as the charge
amount of the high voltage battery,
weather, temperature, durability of
the battery, geographical features,
and driving style.
• Natural degradation may occur with
the high voltage battery depending
on the number of years the vehicle is
used. This may reduce the distance to
empty.
When destination is set
When the destination is set, the distance
to empty may change. The distance
to empty is recalculated using the
information of the destination. However,
the distance to empty may vary
significantly based on traffic conditions,
driving habits, and condition of the
vehicle.
Tips for Improving Distance to
Empty
• If you operate the air conditioner /
heater too much, the driving battery
uses too much electricity. This
may reduce the distance to empty.
Therefore, it is recommended that
you set the cabin temperature to
22°C AUTO. This setting that has
been certified by various assessment
tests to maintain optimal energy
consumption rates while keeping the
temperature fresh.
Turn OFF the heater and air
conditioner if you do not need them.
• When the heater or air conditioning
system is on the energy consumption
is reduced if recirculation mode is
selected instead of selecting the fresh
mode. The fresh mode requires large
amount of energy consumption as
the outside air has to be re-heated or cooled.
• When using the heater or air
conditioning system use the DRIVER
ONLY or scheduled air conditioner/
heater function.
• Depress and hold the accelerator
pedal to maintain speed and drive
economically.
• Gradually depress and release the
accelerator pedal when accelerating
or decelerating.
• Always maintain specified tire
pressures.
• Do not use unnecessary electrical
components while driving.
• Do not load unnecessary items in the
vehicle.
• Do not mount parts that may increase
air resistance.

by the vehicle systems including the
cluster, infotainment system(speaker
and navigation), headlamp, vehicle
control unit, etc.
4. ‘Driving’ shows the total power
and energy consumption of the
driving motor’s driving energy and
regenerative energy.
Power/Charge Gauge
ONE1Q011050
The Power/Charge Gauge shows the
energy consumption rate of the vehicle
and the charge/discharge status of the
regenerative brakes. • POWER :
It shows the energy consumption rate
of the vehicle when driving uphill or
accelerating. The more electric energy
is used, the higher the gauge level.
• CHARGE :
It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerating
or driving on a downhill road). The
more electric energy is charged, the
lower the gauge level.
State Of Charge (SOC) Gauge for
High Voltage Battery
ONE1Q011003
• The SOC gauge shows the charging
status of the high voltage battery.
• The low percentage number on the
indicator indicates that there is not
enough energy in the high voltage
battery. 100 % indicates that the
driving battery is fully charged.
• When driving on highways or
motorways, make sure to check
in advance if the driving battery is
charged enough.

01
1-55
ONE1Q011011
When the remaining battery is lower than
10 % on the SOC gauge, the warning light (
) turns ON to alert you of the battery
level.
When the warning light (
) turns ON,
the vehicle can drive an additional 18 ~
25 miles (30 ~ 40 km) depending on the
driving speed, heater/air conditioner,
weather, driving style, and other factors.
Charging is required.
NOTICE
When the high voltage battery range
shows 25 ~ 30 miles (40 ~ 50 km),
the vehicle speed is limited and then
eventually the vehicle will turn OFF.
Charge the vehicle immediately.
Aux. Battery Saver+
The Aux. Battery Saver+ is a function that
monitors the charging status of the 12 V
auxiliary battery.
If the auxiliary battery level is low, the
main high voltage battery charges the
auxiliary battery.
Information
• The Aux. Battery Saver+ activates
maximum of 20 minutes. If the Aux. Battery Saver+ function activates
more than 10 times consecutively, in
the Automatic Mode the function will
stop activating, judging that there is
a problem with the auxiliary battery.
In this case, drive the vehicle for some
period of time. The function will start activating if the auxiliary battery
returns to normal.
• The Aux. Battery Saver+ function
cannot prevent battery discharge if the auxiliary battery is damaged, worn out,
used as a power supply or unauthorized
electronic devices are used.
• If the Aux. Battery Saver+ function was activated the high voltage battery level
may have decreased.
