What to do in an emergency
If it is hard to loosen the tyre hold-
down wing bolt by hand, you can
loosen it easily using the jack handle.
1. Put the jack handle (1) inside of
the tyre hold-down wing bolt.
2. Turn the tyre hold-down wing bolt
anticlockwise with the jack handle.
When you remove or store the
spare tyre, do not contact or bump
the battery with the spare tyre.
Contacting or bumping the battery
may cause failure of electrical cir-
cuits.
Changing tyres
NOTICE
Never attempt vehicle repairs
in the traffic lanes of a public
road or highway.
Always move the vehicle com-
pletely off the road and onto
the shoulder before trying to
change a tyre. The jack should
be used on firm level ground.
If you cannot find a firm level
place off the road, call a tow-
ing service company for
assistance.
Be sure to use the correct
front and rear jacking posi-
tions on the vehicle; never
use the bumpers or any other
part of the vehicle for jacking
support.
The vehicle can easily roll off
the jack causing serious
injury or death.

WARNING
(Continued)
Do not get under a vehicle
that is supported by a jack.
No person should place any
portion of their body under a
vehicle that is supported by a
jack.
Chock the wheel diagonally
opposite the flat tyre.
Do not start or run the engine
whilst the vehicle is on the
jack.
Do not allow anyone to remain
in the vehicle whilst it is on
the jack.
Make sure any children pres-
ent are in a secure place away
from the road and from the
vehicle to be raised with the
jack.

13. Use the wheel nut wrench to
tighten the wheel nuts in the
order shown. Double-check each
wheel nut until they are tight.
After changing tyres, we recom-
mend that an authorised
HYUNDAI dealer tighten the
wheel nuts to their proper torque
as soon as possible.The wheel
nut should be tightened to
11~13 kgf·m.If you have a tyre gauge, check the
tyre pressure (see "Tyres and
Wheels" in chapter 8 for tyre pres-
sure instructions.). If the pressure is
lower or higher than recommended,
drive slowly to the nearest service
and adjust it to the recommended
pressure. Always reinstall the valve
cap after checking or adjusting tyre
pressure. If the cap is not replaced,
air may leak from the tyre. If you lose
a valve cap, buy another and install it
as soon as possible. After changing
tyres, secure the flat tyre and return
the jack and tools to their proper stor-
age locations.
Check the tyre pressure as soon
as possible after installing a
spare tyre. Adjust it to the rec-
ommended pressure.
Check and tighten the wheel
nuts after driving over 50 km if
tyres are replaced. Re-check the
tyre wheel nuts after driving
1,000 km.If any of the equipment such as the
jack, wheel nuts, studs, or other
equipment is damaged or in poor
condition, do not attempt to change
the tyre and call for assistance.
NOTICE
OTL065007
Your vehicle has metric threads
on the studs and wheel nuts.
Make certain during tyre chang-
ing that the same nuts that were
removed are reinstalled. If you
have to replace your wheel nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub. We
recommend that you consult an
authorised HYUNDAI dealer for
assistance.

What to do in an emergency
Emergency towing
If towing is necessary, we recommend
you have it done by an authorised
HYUNDAI dealer or a commercial tow
truck service.If a 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 as you will have
reduced braking performance.
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 the coolant level in the
engine coolant 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 transmissiom
occurs, check the transmissiom fluid
level.
Check the automatic transmission/
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-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
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 electronic engine control
system produce a considerable
amount of magnetic fields.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, 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 an authorised HYUNDAI
dealer.
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 an authorised HYUNDAI
dealer.
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 ensure
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. When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.

Checking the washer fluid
level
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.
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 an autho-
rised HYUNDAI dealer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).OPD077017L

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
screen and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
Do not allow sparks or flames
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.

Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
over a short time (because, for
example, the headlamps or interior
lights were left on whilst the vehicle
was not in use), recharge it by slow
charging (trickle) for 10 hours.
If the battery gradually discharges
because of high electrical load
whilst the vehicle is being used,
recharge it at 20-30A for two hours.
