Maintenance
Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you use
high alcohol content solutions
or acid/alkaline detergents, the
color of the leather may fade or
the surface may get stripped off.
Cleaning the upholstery and
interior trim
Vinyl (if equipped)
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric's appearance and
fire-resistant properties.
Leather (if equipped)
Features of seat leather
- Leather is made from the outer
skin of an animal, which goes
through a special process to be
available for use. Since it is a nat-
ural product, each part differs in
thickness or density.
Wrinkles may appear as a natural
result of stretching and shrinking
depending on the temperature
and humidity.
- The seat is made of stretchable
fabric to improve comfort.
- The parts contacting the body are
curved and the side supporting
area is high which provides driv-
ing comfort and stability.
- Wrinkles may appear naturally
from usage. It is not a fault of the
products.

The HYUNDAI Hybrid Electric Vehicle (HEV) uses both the gasoline engine and the electric motor for power. The elec-
tric motor is run by a high-voltage HEV battery.
Depending on the driving conditions, the HEV computer selectively operates between the engine and the electric motor
or even both at the same time.
Fuel efficiency increases when the engine is off at idle, or when the vehicle is driven by the electric motor with the HEV
battery.
The HEV battery charge must be maintained, so at times the engine will come on even at idle to act as a generator.
Charging also occurs when decelerating or by regenerative braking.

Plug-in Hybrid Vehicle
The HYUNDAI Plug-in Hybrid Electric Vehicle (PHEV) shares the characteristics of both a conventional hybrid elec-
tric vehicle and an all-electric vehicle.
When used as a conventional hybrid electric vehicle, the HEV computer selectively operates between the engine and
the electric motor or even both at the same time.
When it is operating in the electric vehicle mode, the vehicle is driven only using the electric motor over a certain dis-
tance until the hybrid battery becomes low. The driving distance in EV mode depends on customer driving style and
road conditions. Aggressive driving maneuvers may at times temporarily enable the engine to operate for maximum
power.
The hybrid battery can be fully charged by connecting a plug to an external electric power source.
