What to do in an emergency
Emergency towing
If towing is necessary, we recommend
you 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
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the front (or rear) of the
vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. 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 distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Always follow these emergency tow-
ing precautions:
• Place the ignition switch in the ACC
position so the steering wheel is not
locked.
• Place the shift lever in N (Neutral).
• Release the parking brake.
• Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
• More steering effort will be required because the power steering system
will be disabled.
• Use a vehicle heavier than your own to tow your vehicle.
• The drivers of both vehicles should communicate with each other fre-
quently.
• Before emergency towing, check that the hook is not broken or dam-
aged.
• Fasten the towing cable or chain securely to the hook.
• Do not jerk the hook. Apply steady and even force.

Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the enginecoolant reservoir.
• Check the windscreen washer fluid level.
• Check for low or under-inflated tyres.
Whilst operating your vehicle:
• Note any changes in the sound of the exhaust or any smell of exhaust
fumes in the vehicle.
• Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead position.
• Notice if your vehicle constantly turns slightly or “pulls” to one side when
travelling on smooth, level road.
• When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or
“hard-to-push” brake pedal.
• If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle/ dual clutch transmission P (Park)
function.
• Check the parking brake.
• Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pres-
sure pump, high-pressure
pipes, rail, and injectors are still
subject to the high pressure
right after stopping the diesel
engine.
When the fuel leakage vents
out, it may cause serious body
injury. Any people, who are
implemented with the artificial
cardiac pacemaker, should
remain away from the ECU or
the wiring harness by at least 30
cm, whilst running the diesel
engine. The high currents of the
electric engine control system
produce a considerable amount
of magnetic fields.

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-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuel
filter should be replaced.
Upon installing a new fuel filter, oper-
ate the diesel engine for several min-
utes, and check the connections for
any leakages. We recommend you to
have the fuel filter 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 connections be
replaced by a HYUNDAI authorised
repairer.
When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
CAUTION
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
the high pressure right after
stopping the diesel engine. When
the fuel leakage vents out, it may
cause serious body injury. Any
people, who are implemented
with the artificial cardiac pace-
maker, should remain away from
the ECU or the wiring harness by
at least 30 cm whilst running the
diesel engine. The high currents
of the common rail system pro-
duce a considerable amount of
magnetic fields.

Maintenance
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. 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 con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
We recommend that the air cleaner
filter be replaced by a HYUNDAI
authorised repairer.
Spark plugs
(For Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(For Petrol Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by a HYUNDAI authorised
repairer.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses
and connections for leakage and dam-
age. Replace any damaged parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not
be checked under normal usage
conditions. We recommend that the
automatic transaxle fluid changed by
a HYUNDAI authorised repairer
according to the maintenance sched-
ule.
Information
Automatic transaxle fluid colour is
basically 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.
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Maintenance
Make sure the coolant cap is prop-
erly closed after refill of coolant.
Otherwise the engine could be over-
heated whilst driving.
1. Check if the radiator cap label is straight In front.
(Continued)(Continued)
2. Make sure that the tiny protru-
sions inside the coolant cap
should be securely interlocked.
Recommended engine coolant
• When adding coolant, use onlydeionised water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
• The engine in your vehicle has alu- minum engine parts and must be
protected by an Phosphate-based
Ethylene glycol coolant to prevent
corrosion and freezing.
• DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
• Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the solu-
tion.

WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary.
Plain water may be used if washer
fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard whilst fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, we recommend that
the system be serviced by a
HYUNDAI authorised repairer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
