Foreword / Electric Vehicle System Overview

•
If over time the maximum charge capacity and the maximum electric
range begin to degrade, contact
an authorized HYUNDAI dealer for
inspection and maintenance.
• If the vehicle will not be used for
an extended amount of time, it is
recommended to fully charge the
vehicle to 100% before storing, and
then charge the vehicle periodically
(approximately every 3 months)
to prevent the EV battery from
discharging completely.
• AC charge is recommended to keep
the high voltage battery in optimal condition.
Avoid storing the vehicle with a low
battery SOC % (e.g. below 20%).
Storing the vehicle with the EV battery
capacity at a low SOC may damage
the battery over time.
• Make sure to use a designated
charger when charging the high
voltage battery. Using different types
of chargers may have a serious impact
on vehicle durability.
CAUTION
• If the vehicle is kept at “H (High)”
for a long period, it may damage
the high voltage battery and the
high voltage battery may have to be
replaced depending on the level of
degradation.
• If the vehicle is in a collision, we
recommend that you contact an
authorized HYUNDAI dealer to
inspect whether the high voltage
battery is still connected.
EV Battery Coolant Heater (if equipped)
When charging your vehicle, the EV
battery coolant heater may be turned on
to increase battery temperature when
the battery temperature is low (i.e. in
cold weather conditions). This allows
the EV battery to charge at nominal
temperatures and helps to improve
battery life.
Note that when the vehicle is being
charged some of the electrical current
coming from the charger is being
used to operate the EV battery coolant
heater. Electrical power consumption
for charging may be slightly higher than normal.
CAUTION
The high voltage battery warmer
system operates when the charging
connector is connected to the vehicle.
However, the high voltage warmer
system may not operate when battery
temperature drops below -35°C (-31°F).

Curb weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT markings
The DOT code includes the Tire
Identification Number (TIN), an
alphanumeric designator which can
also identify the tire manufacturer,
production plant, brand and date of
production.
GVWR
Gross Vehicle Weight Rating
GAWR FRT
Gross Axle Weight Rating for the
Front Axle.
GAWR RR
Gross Axle Weight Rating for the
Rear axle.
Intended outboard sidewall
The side of an asymmetrical tire,
that must always face outward when
mounted on a vehicle.
Kilopascal (kPa)
The metric unit for air pressure.
Light Truck (LT) tire
A tire designated by its manufacturer
as primarily intended for use on
lightweight trucks or multipurpose
passenger vehicles.
Load ratings
The maximum load that a tire is rated
to carry for a given inflation pressure.
Load index
An assigned number ranging from 1
to 279 that corresponds to the load
carrying capacity of a tire.
Maximum inflation pressure
The maximum air pressure to which
a cold tire may be inflated. The
maximum air pressure is molded
onto the sidewall.
Maximum load rating
The load rating for a tire at the
maximum permissible inflation
pressure for that tire.
Maximum loaded vehicle weight
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal occupant weight
The number of occupants a vehicle
is designed to seat multiplied by 150
pounds (68 kg).
Occupant distribution
Designated seating positions.
Outward facing sidewall
An asymmetrical tire has a particular
side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or deeper than the same moldings
on the inner facing sidewall.
Passenger (P-Metric) tire
A tire used on passenger cars
and some light duty trucks and
multipurpose vehicles.
