What to do in an emergency
6If any of the equipment such as the
jack, lug nuts, studs, or other equip-
ment is damaged or in poor condi-
tion, do not attempt to change the
tire and call for assistance.
Use of compact spare tires
Compact spare tires are designed for
emergency use only. Drive carefully
on the compact spare tire and
always follow the safety precautions.When driving with the compact spare
tire mounted to your vehicle:
Check the tire pressure after
installing the compact spare tire.
The compact spare tire should be
inflated to 60 psi (420 kPa). Do not take this vehicle through an
automatic car wash while the com-
pact spare tire is installed.
Do not use the compact spare tire on any other vehicle because this
tire has been designed especially
for your vehicle.
The compact spare tire’s tread life is shorter than a regular tire. Inspect
your compact spare tire regularly
and replace worn compact spare
tires with the same size and design,
mounted on the same wheel.
Do not use more than one com- pact spare tire at a time.
Do not tow a trailer while the com- pact spare tire is installed.
When the original tire and wheel
are repaired and reinstalled on the
vehicle, the lug nut torque must be
set correctly. The correct lug nut
tightening torque is 79~94 lbf·ft
(11~13 kgf·m).
NOTICE
Your vehicle has metric threads
on the studs and lug nuts. Make
certain during tire changing that
the same nuts that were
removed are reinstalled. If you
have to replace your lug nuts
make sure they have metric
threads to avoid damaging the
studs and ensure the wheel is
properly secured to the hub.
Consult an authorized HYUNDAI
dealer for assistance.
CAUTION
To prevent compact spare tire
failure and loss of control pos-
sibly resulting in an accident:
Use the compact spare tire
only in an emergency.
NEVER operate your vehicle
over 50 mph (80 km/h).
Do not exceed the vehicle's
maximum load rating or the
load carrying capacity shown
on the sidewall of the com-
pact spare tire.
Do not use the compact spare
tire continuously. Repair or
replace the original tire as
soon as possible to avoid fail-
ure of the compact spare tire.

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
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 engine for several minutes,
and check the connections for any
leakages. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
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 a new vapor
hose or fuel filler cap is correctly
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.
