Maintenance
Auxiliary battery (VAN/Truck)
The auxiliary battery is located in
engine room. (if equipped)
Keep the battery securely mount-ed.
Keep the battery top clean and dry.
Keep the terminals and connec- tions clean, tight, and coated with
petroleum jelly or terminal grease.
Rinse any spilled electrolyte from the battery immediately with a
solution of water and baking soda. Basically equipped battery is
maintenance free type. If your
vehicle is equipped with the bat-
tery marked with LOWER and
UPPER on the side, you can check
the electrolyte level. The elec-
trolyte level should be between
LOWER and UPPER. If the elec-
trolyte level is low, it needs to add
distilled (demineralized) water
(Never add sulfuric acid or other
electrolyte). When refill, be careful
not to splash the battery and adja-
cent components. And do not
overfill the battery cells. It can
cause corrosion on other parts.After then ensure that tighten the
cell caps. We recommend that you
contact an authorized HYUNDAI
dealer.
NOTICE
Do not open the AGM battery.
WARNING

authorized HYUNDAI dealer.
There is a vent hose for
degasing. You must check the
connection for venting when
you change the battery.

Disconnect the battery charg-
er in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery ter-minal.
3. Unhook the positive clamp from the positive battery ter-minal.
4. After recharging, park the vehicle for about 5 hours with
the hood and all doors
closed. During this period,
the dark current must be
under 100mA.(AGM battery
only)
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and stop the engine.
The negative battery cable
must be removed first and
installed last when the batteryis disconnected.
Do not open the AGM battery.
WARNING
Recharging battery
When recharging the battery,
observe the following precau-tions:
The battery must be removed
from the vehicle and placed inan area with good ventilation.
Do not allow cigarettes,
sparks, or flame near the bat-
tery.
Watch the battery during
charging, and stop or reduce
the charging rate if the batterycells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
Do not charge the AGM bat-
tery with over 14.5V. No quick-
charging routines
Wear eye protection when
checking the battery during
charging.

4. Tire ply composition andmaterial
The number of layers or plies of rub-
ber-coated fabric are in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and theletter "B" means belted-bias ply con-
struction.
5. Maximum permissible infla-tion pressure
This number is the greatest amountof air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.
6. Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 3 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside thefuse will be melted.

Inner panel fuse replacement1.Turn the ignition switch and allother switches off.
2.Open the fuse panel cover.
3.Pull the suspected fuse straightout. Use the removal tool provided
in the engine compartment fusepanel.
4.Check the removed fuse; replace it if it is blown.
5.Push in a new fuse of the same rat- ing, and make sure it fits tightly in
the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
If you do not have a spare, use a
fuse of the same rating from a circuit
you may not need for operating the
vehicle, such as the cigar lighter
fuse.

3. Exhaust emission control system
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
Vehicle modifications
This vehicle should not be modi-fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or perform-
ance problems resulting from any
modification may not be covered
under warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust gas precautions
(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes.
Therefore, if you smell exhaust
fumes of any kind inside your vehi-
cle, have it inspected and repaired
immediately. If you ever suspect
exhaust fumes are coming into
your vehicle, drive it only with all
the windows fully open. Have your
vehicle checked and repaired
immediately. Do not operate the engine in con-
fined or closed areas (such as
garages) any more than what is
necessary to move the vehicle in orout of the area.
When the vehicle is stopped in an open area for more than a short
time with the engine running,
adjust the ventilation system (as
needed) to draw outside air into the
vehicle.
Never sit in a parked or stopped vehicle for any extended time with
the engine running.
When the engine stalls or fails to start, excessive attempts to restart
the engine may cause damage tothe emission control system.
Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-ing.

Maintenance
Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot according to the driving condi-
tion. In other words, the active burn-
ing by engine control system and
high exhaust gas temperature
caused by normal/high driving condi-
tion burns and removes the accumu-lated soot.
However, if the vehicle continues to
be driven in short distance repeated-
ly or at low speed for a long time, the
accumulated soot may not be auto-
matically removed because of low
exhaust gas temperature. In this par-
ticular case, if the amount of soot is
out of detection limit, the DPF warn-
ing indicator ( ) will illuminate. In order to start the DPF regenera-
tion and to stop the DPF warning
lamp illuminating, drive the vehicle in
a safety driving circumstance with
more than 60km/h (37 mph) vehiclespeed or with more than secondgear engaged and 1500 ~ 2000
engine rpm for a certain time (for
about 25 minutes).
If the DPF warning indicator( )
continues to blink or "check emissionsystem" message comes on in the
cluster in spite of the above proce-
dure, we recommend that the system
be checked by an authorized
HYUNDAI dealer.
If you continue to drive with the indi-
cator light blinking for a long time, theDPF system can be damaged and
fuel consumption can be worsen.Diesel Fuel (if equipped with DPF) It is recommended to use the regulated automotive diesel
fuel for diesel vehicle equippedwith the DPF system.
If you use diesel fuel including high sulfur (more than 50 ppm
sulfur) and unspecified addi-
tives, it can cause the DPF sys-
tem to be damaged and whitesmoke can be emitted.
