Understanding Your Electric Vehicle
Electric vehicles are driven using a battery and an electric motor. Understand the
characteristics of your electric vehicle and check the features that you must know before
driving it.
Characteristics of Your Electric Vehicle
The characteristics that differentiate electric vehicles from gasoline vehicles are as
follows:
• Electric vehicles are eco-friendly because they do not use fossil fuels for driving. Additionally, unlike gasoline vehicles, noise and vibration are minimal, and the
vehicle’s lifespan is relatively long.
• When slowing down or driving downhill, regenerative braking is used. Regenerative braking charges the high voltage battery and minimizes energy loss.
• If the high voltage battery is running low, you can charge the vehicle using the AC charger, DC charger, or portable charging cables. For more information, refer to the
"Charging Your Electric Vehicle" section in this chapter.
Information Regenerative braking uses an electric motor when decelerating and braking, and it transforms
kinetic energy to electrical energy in order to charge the high voltage battery.
Battery information
The batteries used in the electric vehicle are as follows:
•High voltage battery (high capacity) : Drives the motor and operates the air
conditioner and heater. It can be charged via an AC charger, DC charger, or portable
charger.
• 12 V battery : Operates all lights, wipers, and audio system. The 12 V battery charge can
also be maintained by the high voltage battery at parked condition at certain
conditions.
Main components of your electric vehicle
The main components of your electric vehicle and their functions are as follows:
• On-Board Charger (OBC) : Charges the high voltage battery by converting the power
grid’s AC power to DC power.
• Inverter : Converts power from direct current (DC) to alternating current (AC) and
supplies power to the motor, and converts power from AC to DC to charge the high
voltage battery during deceleration and braking.
• Low Voltage DC-DC Converter (LDC) : Converts the high voltage battery’s power
source to a low voltage (12 V) power source for supply of power to the electrical devices
on the vehicle.

Certification label
OBH059070
The certification label is located on
the driver's door sill at the center
pillar and shows the maximum
allowable weight of the fully loaded
vehicle. This is called the GVWR
(Gross Vehicle Weight Rating). The
GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle,
including all occupants, accessories,
cargo, and trailer tongue load must
not exceed the Gross Vehicle Weight
Rating (GVWR) or the Gross Axle
Weight Rating (GAWR). To find out
the actual loads on your front and
rear axles, you need to go to a weigh
station and weigh your vehicle. Be
sure to spread out your load equally
on both sides of the centerline.
WARNING Overloading
• Never exceed the GVWR for your vehicle, the GAWR for either the
front or rear axle and vehicle
capacity weight. Exceeding these ratings can affect your vehicle's
handling and braking ability, and
cause an accident.
• Do not overload your vehicle. Overloading your vehicle can cause
heat buildup in your vehicle's tires and
possible tire failure, increased stopping
distances and poor vehicle handling-all
of which may result in a collision.

WARNING If you carry items inside your vehicle
(for example, suitcases, tools,
packages, or anything else), they are
moving as fast as the vehicle. If you
have to stop or turn quickly, or if there
is a crash, the items will keep going
and can cause an injury if they strike
the driver or a passenger.
• Put items in the cargo area of your vehicle. Try to spread the weight
evenly.
• Do not stack items, like suitcases, inside the vehicle above the tops of
the seats.
• Do not leave an unsecured child restraint in your vehicle.
• When you carry something inside the vehicle, secure it.
Trailer Towing
We do not recommend using this vehicle
for trailer towing.

Temperature - A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specified indoor
laboratory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. Grades B and A
represent higher levels of
performance on the laboratory test
wheel than the minimum required by
law.
WARNING The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.
Excessive speed, under-inflation,
over-inflation, or excessive loading,
either separately or in combination,
can cause heat build-up and possible
sudden tire failure. This may cause
loss of vehicle control resulting in an
accident.
Tire Terminology and
Definitions
Air pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in lbs. per
square in. (psi) or kilopascal (kPa).Accessory weight
This means the combined weight of
optional accessories. Some examples
of optional accessories are gear,
power seats, and air conditioning.
Aspect ratio
The relationship of a tire’s height to
its width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias ply tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold tire pressure
The amount of air pressure in a tire,
measured in lbs. per square in. (psi) or
kilopascals (kPa) before a tire has
built up heat from driving.
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.
