Turn signals when towing a trailer
When you tow a trailer, your vehicle
has to have a different turn signal
flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever you signal a turn or
lane change. Properly connected,
the trailer lights will also flash to alert
other drivers you’re about to turn,
change lanes, or stop.
When towing a trailer, the green
arrows on your instrument panel will
flash for turns even if the bulbs on
the trailer are burned out. Thus, you
may think drivers behind you are
seeing your signals when, in fact,
they are not. It is important to check
occasionally to be sure the trailer
bulbs are still working. You must also
check the lights every time you dis-
connect and then reconnect the
wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle’s lighting
system. Use only an approved trailer
wiring harness.
A HYUNDAI authorised repairer can
assist you in installing the wiring har-
ness.
Driving on grades
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
hot and no longer operate efficiently.
On a long uphill grade, shift down
and reduce your speed to around 45
mph (70 km/h) to reduce the possi-
bility of engine and transaxle over-
heating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transaxle, you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimise
heat build up and extend the life of
your transaxle.WARNING
Failure to use an approved trail-
er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.

WARNING -
Maintenance work
• Performing maintenance work
on a vehicle can be danger-
ous. You can be seriously
injured whilst performing
some maintenance proce-
dures. If you lack sufficient
knowledge and experience or
the proper tools and equip-
ment to do the work, we rec-
ommend that the system be
servied by a HYUNDAI autho-
rised repairer.
• Working under the bonnet
with the engine running is
dangerous. It becomes even
more dangerous when you
wear jewellery or loose cloth-
ing.
(Continued)
(Continued)
These can become entangled
in moving parts and result in
injury. Therefore, if you must
run the engine whilst working
under the bonnet, make cer-
tain that you remove all jew-
ellery (especially rings,
bracelets, watches, and neck-
laces) and all neckties,
scarves, and similar loose
clothing before getting near
the engine or cooling fans.CAUTION
• Do not put heavy objects or
apply excessive force on top
of the engine cover (if
equipped) or fuel related
parts.
• When you inspect the fuel
system (fuel lines and fuel
injection devices), we recom-
mend that you contact a
HYUNDAI authorised repairer.
• Do not drive long time with the
engine cover (if equipped)
removed.
• When checking the engine
room, do not go near fire.
Fuel, washer fluid, etc. are
flammable oils that may cause
fire.
• Before touching the battery,
ignition cables and electrical
wiring, you should disconnect
the battery "-" terminal. You
may get an electric shock
from the electric current.

Maintenance
Engine compartment precau-
tions (Diesel engine)
• The piezo injector operates at high
voltage (maximum 200v).
Therefore, the following accidents
may occur.
- Direct contact with the injector or
injector wiring may cause electric
shock or damage your muscle or
nerve system.
- The electromagnetic wave from
the operating injector may cause
the artificial heart pacemaker to
malfunction.
• Follow the safety tips provided
below, when you are checking the
engine room whilst the engine is
running.
- Do not touch the injector, injector
wirings, and the engine computer
whilst the engine is running.
- Do not remove the injector con-
nector whilst the engine is run-
ning.
- People using pacemakers must
not go near the engine whilst the
engine is starting or running.
WARNING- Diesel Engine
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High-pressure pump,
rail, injectors and high-pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touches the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
whilst engine is running, since
the high currents in the elec-
tronic engine control system
produce considerable magnetic
fields.(Continued)
• When you remove the interior
trim cover with a flat head (-)
driver, be careful not to dam-
age the cover.
• Be careful when you replace
and clean bulbs to avoid
burns or electrical shock.

Maintenance
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by a HYUNDAI authorised
repairer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connectionsr be
replaced by a HYUNDAI authorised
repairer.
WARNING - Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressure
pipes are subject to high pres-
sure even after the engine
stopped. The fuel jet produced
by fuel leaks may cause serious
injury, if it touch the body.
People using pacemakers
should not move than 30cm
closer to the ECU or wiring har-
ness within the engine room
whilst engine is running, since
the high currents in the
Common Rail system produce
considerable magnetic fields.
CAUTION
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.

Maintenance
FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment 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 the
fuse will be melted.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult a HYUNDAI autho-
rised repairer.
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
WARNING - Fuse
replacement
• Never replace a fuse with any-
thing but another fuse of the
same rating.
• A higher capacity fuse could
cause damage and possibly a
fire.
• Never install a wire or alu-
minum foil instead of the prop-
er fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible
fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the
system.

Inner panel fuse replacement
1. Turn the ignition switch and all
other switches off.
2. Open the fuse panel cover.3. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuse
panel.
4. Check the removed fuse; replace it
if it is blown.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips.
If it fits loosely, we recommend that
you consult a HYUNDAI authorised
repairer.
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.

CAUTION
• When replacing a blown fuse
or relay with a new one, make
sure the new fuse or relay fits
tightly into the clips. The
incomplete fastening fuse or
relay may cause the vehicle
wiring and electric systems
damage and a possible fire.
• Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses, relays
and terminals may be fas-
tened incompletely, and it may
cause a possible fire. If fuses,
relays and terminals fastened
with bolts or nuts are blown,
we recommend that you con-
sult a HYUNDAI authorised
repairer.
• Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause
contact failure and system
malfunction.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy, driving rain or wash-
ing, headlight and taillight lenses
could appear frosty. This condition
is caused by the temperature differ-
ence between the lamp inside and
outside. This is similar to the con-
densation on your windows inside
your vehicle during the rain and
doesn’t indicate a problem with
your vehicle. If the water leaks into
the lamp bulb circuitry, we recom-
mend that the system be checked by
a HYUNDAI authorised repairer.WARNING - Working on
the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the “LOCK” position
and turn off the lights to avoid
sudden movement of the vehi-
cle and burning your fingers or
receiving an electric shock.
CAUTION
Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION
If you don’t have necessary
tools, the correct bulbs and the
expertise, consult a HYUNDAI
authorised repairer. In many
cases, it is difficult to replace
vehicle light bulbs because
other parts of the vehicle must
be removed before you can get
to the bulb. This is especially
true if you have to remove the
headlight assembly to get to the
bulb(s).
Removing/installing the head-
light assembly can result in
damage to the vehicle.
