Emergency towing
If towing is necessary, we recommend
you to have it done by a HYUNDAI
authorised repairer or a commercial
tow truck service. If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed using a cable or chain
secured to the emergency towing hook
under the front (or rear) of the vehicle.
Use extreme caution when towing the
vehicle. A driver must be in the vehicle to
steer it and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speed. Also, the wheels,
axles, power train, steering and brakes
must all be in good condition.
 Do not use the towing hooks to pull a
vehicle out of mud, sand or other con-
ditions from which the vehicle cannot
be driven out under its own power.
 Avoid towing a vehicle heavier than the vehicle doing the towing.
 The drivers of both vehicles should communicate with each other frequent-
ly.  Before emergency towing, check that
the hook is not broken or damaged.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the hook. Apply steady and even force.
 To avoid damaging the hook, do not pull from the side or at a vertical angle.
Always pull straight ahead.
CAUTION
 Attach a towing strap to the tow
hook.
 Using a portion of the vehicle other than the tow hooks for tow-ing may damage the body of yourvehicle.
 Use only a cable or chain specifi- cally intended for use in towingvehicles. Securely fasten thecable or chain to the towing hook provided.

Engine compartment precautions (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 arti-
ficial 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 connector whilst the engine is running.
- People using pacemakers must not go near the engine whilst the engine
is starting or running.
WARNING - Maintenance
work
 Performing maintenance work on a vehicle can be dangerous. You
can be seriously injured whilst
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, we recommend that the
system be serviced by a
HYUNDAI authorised repairer.
 Working under the bonnet with the engine running is dangerous.
It becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine whilst work-
ing under the bonnet, make cer-
tain that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and all
neckties, scarves, and similar
loose clothing before gettingnear the engine or cooling fans.WARNING - Diesel Engine
Never work on injection system with engine running or within 30
seconds after shutting off engine.
High-pressure pump, rail, injectorsand high-pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touches the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
electronic engine control system
produce considerable magneticfields.

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 fre-quent oil and filter changes are required. Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically forproper tension and adjusted as neces-
sary. 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 exces-
sive amount of foreign matter accumu-
lates 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 con-
nections for leakage and damage. We
recommend that the fuel lines, fuel hoses
and connections 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, injectorsand high pressure pipes are sub-
ject to high pressure even after the
engine stopped. The fuel jet pro-
duced by fuel leaks may cause seri-
ous injury, if it touch the body.
People using pacemakers should
not move than 30cm closer to theECU or wiring harness within the
engine room whilst engine is run-
ning, since the high currents in the
Common Rail system produce con-
siderable magnetic fields.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller cap is correctly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with
any heat source, sharp edges or movingcomponent which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.Air cleaner filter
We recommend that you use air cleaner
filter for replacement from a HYUNDAI
authorised repairer.
Spark plugs (for petrol engine)
Make sure to install new spark plugs of
the correct heat range. Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid (if equipped)
Automatic transaxle fluid should not be
checked under normal usage conditions.
But in severe conditions, we recommend
that the fluid be changed by a HYUNDAI
authorised repairer in accordance to thescheduled maintenance at the beginning
of this chapter.
✽✽
NOTICE
Automatic transaxle fluid colour is basi-
cally red. As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.It is normal condition and you should
not judge the need to replace the fluid
based upon the changed colour.

Maintenance
PARKING BRAKE
Check the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heardwhilst fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, we recommend that
the system be checked by a HYUNDAI
authorised repairer.
Stroke : 6 “clicks’’ at a force of 44 lbs (20 kg, 196 N). Draining water from fuel filter
The fuel filter for diesel engine plays an
important role of separating water from
fuel and accumulating the water in itsbottom.
If water accumulates in the fuel filter, the
warning light comes on when the ignition
switch is in the ON position.
If this warning light illuminates,
we recommend that the system
by checked by a HYUNDAI
authorised repairer.
Extracting air from the fuel filter
If you drive until you have no fuel left or if
you replace the fuel filter, be sure to
extract air from the fuel system as it
makes it difficult to start the engine.
1. Pump up and down(1) approximately50 times until the pump is hard.
2. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
3. Pump up and down(1) approximately 15 times.
4. Extract air from the fuel filter by remov- ing the bolt(2) with a cross-tip screw
driver and reinstall the bolt(2).
5. Pump up and down(1) approximately 5 times.
CAUTION
If the water accumulated in the fuel
filter is not drained at proper times,
damages to the major parts such asthe fuel system can be caused by water permeation in the fuel filter.
