Maintenance
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.
Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Do not use abrasive cleaner, pol-
ishing compound, solvent, or
wire brushes on aluminum
wheels.
Clean the wheel when it has cooled.
Use only a mild soap or neutral detergent, and rinse thoroughly
with water. Also, clean the
wheels after driving on salted
roads.
Do not wash the wheels with high-speed car wash brushes.
Do not use any cleaners con- taining acid or alkaline deter-
gents.
NOTICE
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.

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.

Stop vehicle and check brakes
This warning message is displayed
when a failure occurs in the brake
system.
In this case, park the vehicle in a
safe location and recommend that
you tow your vehicle to the nearest
authorized HYUNDAI dealer and
have the vehicle inspected.
Check brakes
This warning message is displayed
when the brake performance is low
or the regenerative brake does not
work properly due to a failure in the
brake system.
In this case, it may take longer for the
brake pedal to operate and the brak-
ing distance may become longer.
Low Battery
When the high voltage battery level
reaches below 13%, this warning
message is displayed.
The warning light on the instrument
cluster ( ) will turn ON simultane-
ously.
Charge the high voltage battery
immediately.
