12. Lower vehicle and tighten nuts
Lower the vehicle to the ground by
turning the release valve on the jack
counterclockwise. Then position the
wrench as shown in the drawing and
tighten the wheel nuts. Be sure the
socket is seated completely over the
nut. Do not stand on the wrench han-
dle or use an extension pipe over the
wrench handle. Go around the wheel tightening
every other nut until they are all tight.
Then double-check each nut for
tightness. After changing wheels,
have a technician tighten the wheel
nuts to their proper torque as soon
as possible.Wheel nut tightening torque:
Steel wheel & aluminum alloy wheel:
9~11 kg.m (67~81 lb.ft)
If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting tire pressure. If the cap is
not replaced, air may leak from the
tire. If you lose a valve cap, buyanother and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.

What to do in an emergency
To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
Important - use of compactspare tire (if equipped)
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
You should drive carefully when the compact spare is in use. The compact spare should be
replaced by the proper conven-
tional tire and rim at the first
opportunity.
The operation of this vehicle is not recommended with morethan one compact spare tire in
use at the same time.
NOTICE
Your vehicle has metric threads
on the wheel studs and nuts.
Make certain during wheel
removal that the same nuts that
were removed are reinstalled -
or, if replaced, that nuts withmetric threads and the same
chamfer configuration are used.Installation of a non-metric
thread nut on a metric stud or
vice-versa will not secure the
wheel to the hub properly and
will damage the stud so that it
must be replaced.
Note that most lug nuts do not
have metric threads. Be sure to
use extreme care in checking
for thread style before installing
aftermarket lug nuts or wheels.
If in doubt, we recommend that
you consult an authorized
HYUNDAI dealer.
CAUTION
Inadequate spare tire pressure
Check the inflation pressures
as soon as possible after
installing the spare tire. Adjust
it to the specified pressure, if
necessary. Refer to “Tires and
wheels” in section 8.
WARNING
Wheel studs
If the studs are damaged, they
may lose their ability to retain
the wheel. This could lead to theloss of the wheel and a collisionresulting in serious injuries.

What to do in an emergency
Emergency towing
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer 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 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 distance and at low speed.
Also, the wheels, axles, power train,
steering and brakes must all be ingood condition.
Do not use the towing hooks to pull
a vehicle out of mud, sand or other
conditions 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 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.
To avoid damaging the hook, do not pull from the side or at a verti-
cal angle. Always pull straightahead.

burns or electrical shock.
Engine compartment precau- tions (Diesel engine)
• Follow the safety tips providedbelow, when you are checking the engine room while the engine is
running.
- Do not touch the injector, injectorwirings, and the engine computer
while the engine is running.
- Do not remove the injector con- nector while the engine is run-ning.
- People using pacemakers must not go near the engine while the
engine is starting or running. Diesel Engine
Never work on injection system with engine running or within 30seconds after shutting off
engine. High-pressure pump,
rail, injectors and high-pressurepipes 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
while engine is running, sincethe high currents in the elec-
tronic engine control system
produce considerable magneticfields.

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 filterchanges 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 authorized 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 connection be
replaced by an authorized HYUNDAI
dealer.
When you are inspecting the
belt, place the ignition switch in
the LOCK/OFF or ACC position.
CAUTION
In case the fuel filter is clogged
due to not conforming to the
maintenance period, the fuel
injection equipment may supply
the fuel insufficiently, which
may damage the fuel injectionequipment and cause the
engine to stall at worst cases.
CAUTION
Diesel only
Never work on injection system with engine running or within 30seconds after shutting off
engine. High pressure pump,
rail, injectors and high pressurepipes 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
while engine is running, sincethe high currents in the
Common Rail system produce
considerable magnetic fields.

Maintenance
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor 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 whichmight 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 an authorized
HYUNDAI dealer.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.

Maintenance
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while 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 author-
ized HYUNDAI dealer.
Stroke : 7 “clicks’’ at a force of
20 kg (44 lbs, 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 waterin its bottom.
If water accumulates inthe fuel filter, the warninglight comes on when the
ignition switch is in the ONposition.
If this warning light turned
on, we recommend that
the system be serviced by
an authorized HYUNDAI
dealer.
Fuel filter cartridge replace- ment
When replacing the fuel filter car-
tridge, we recommend that you
use parts for replacement from an
authorized HYUNDAI dealer.
