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.

the doors are securely closed and
locked.
• Adjust the position of the seat and
steering wheel.
• Adjust the inside and outside rearview
mirrors.
• Verify all the lights work.
• Fasten your seat belt. Check that all

• Check the gauges and indicators
in the instrument panel and the
messages on the instrument display
when the vehicle is in the ON position. •
Check that any items you are carrying

WARNING
To reduce the risk of SERIOUS INJURY or

whenever the vehicle is moving.
For more information, refer to “Seat

WARNING
NEVER drink or take drugs and drive. Drinking or taking drugs and driving
is dangerous and may result in an
accident and SERIOUS INJURY or
DEATH. Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Just
one drink can reduce your ability to
respond to changing conditions and
emergencies and your reaction time
gets worse with each additional drink.
Driving while under the influence
of drugs is as dangerous or more
dangerous than driving under the
influence of alcohol.
You are much more likely to have a
serious accident if you drink or take
drugs and drive. If you are drinking or
taking drugs, don’t drive. Do not ride
with a driver who has been drinking
or taking drugs. Choose a designated
driver or call a taxi.
