Maintenance
Longer wearing tires can be more
susceptible to irregular tread wear. It
is very important to follow the tire
rotation interval in this chapter to
achieve the tread life potential of
these tires. Cuts and punctures in
radial-ply tires are repairable only in
the tread area, because of sidewall
flexing. Consult your tire dealer for
radial-ply tire repairs.
Low Aspect Ratio Tires
(if equipped)
Low aspect ratio tires, the aspect
ratio is lower than 50, are provided
for sporty looks.
Because low aspect ratio tires are
optimized for handling and braking,
their sidewall is a little stiffer than a
standard tire. Also low aspect ratio
tires tend to be wider and conse-
quently have a greater contact patch
with the road surface. In some
instances they may generate more
road noise compared with standard
tires.
Do not mix bias ply and radial
ply tires under any circum-
stances. This may cause unusu-
al handling characteristics that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING
Because the sidewall of a low
aspect ratio tire is shorter than
a standard tire, the rim of the
wheel and the tire itself is more
easily susceptible to damage.
Use caution when driving and
follow the guidelines below to
help minimize damage to the
wheel and tire:
•When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driv-
ing, inspect tires and wheels.
When passing over a pothole,
speed bump, manhole, or
curb stone, drive slowly so
that the tires and wheels are
not damaged.
If the tire is subjected to a
severe impact, have the tire
and wheel inspected by an
authorized HYUNDAI dealer.
Inspect the tire condition and
pressure every 1,800 miles
(3,000 km).

When replacing tires, use the same size originally supplied with the vehicle.
Using tires of a different size can damage the related parts or not work properly.
CAUTION
If your vehicle is not equipped with a compact spare tire, your vehicle will be equipped with a Tire Mobility Kit.

It is permissible to add 3 psi to the standard tire pressure specification if colder temperatures are expect- ed soon.
Tires typically loose 1psi (7kPa) for every 12°F temperature drop. If extreme temperature variations are
expected, recheck your tire pressure as necessary to keep them properly inflated.
An air pressure generally decreases, as you drive up to a high-altitude area above sea level. Thus, if you plan to drive a high-altitude area, check the tire pressures in advance. If necessary, inflate them to a prop-
er level. (Air inflation per altitude : +2.4 psi/1 mile)

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
73°F (23°C) AUTO. This setting that
has been certified by various
assessment tests to maintain opti-
mal energy consumption rates while
keeping the temperature fresh.
Turn OFF the heater and air condi-
tioner if you do not need them.
Depress and hold the accelerator pedal to maintain speed and drive
economically.
Gradually depress and release the accelerator pedal when accelerat-
ing 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.
ECO Guide
The ECO guide 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 ener-
gy is used, the higher the gauge level.
ECO :
It shows the energy consumption
rate during normal driving condition.
It shows the charging status of the
battery when it is being charged by
the regenerative brakes (decelerat-
ing or driving on a downhill road).
The more electric energy is charged,
the lower the gauge level.
