Exterior Care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
Protecting your vehicle’s finish
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should be
used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

Maintenance
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
WARNING
Repairing your vehicle’s finish
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion mate-
rials to the parts repaired or
replaced.
Matte paint finish vehicle
(if equipped)
In case of matte paint finish vehi-
cles, it is impossible to modify
only the damaged area and repair
of the whole part is necessary. If
the vehicle is damaged and paint-
ing is required, we recommend
that you have your vehicle main-
tained and repaired by an author-
ized HYUNDAI dealer. Take
extreme care, as it is difficult to
restore the quality after the repair.
Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end
of each winter. Pay special attention
to these areas because it is difficult
to see all the mud and dirt. It will do
more harm than good to wet down
the road grime without removing it.
The lower edges of doors, rocker
panels, and frame members have
drain holes that should not be
allowed to clog with dirt; trapped
water in these areas can cause rust-
ing.

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.
Power/Charge Gauge
The Power/Charge Gauge shows the
energy consumption rate of the vehi-
cle 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.
CHARGE :
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.
State of Charge (SOC) Gauge
for High Voltage Battery
The SOC gauge shows the charg-
ing status of the high voltage bat-
tery.
"L (Low)" position on the indicator
indicates that there is not enough
energy in the high voltage battery.
"H (High)" position indicates that
the driving battery is fully charged.
When driving on highways or
motorways, make sure to check in
advance if the driving battery is
charged enough.

message is displayed.
The warning light on the instrument
cluster ( ) will turn ON simultane-
ously.
Charge the high voltage battery
immediately.
Charge immediately.
Power limited
When the high voltage battery level
reaches below 6%, this warning
message is displayed.
The warning light on the instrument
cluster ( ) and the power down
warning light ( ) will turn on simul-
taneously.
The vehicle's power will be reduced
to minimize the energy consumption
of the high voltage battery. Charge
the battery immediately.OOSEV048118L/OOSEV048117N
