If you have a tyre gauge, check the tyre
pressure (see “Tyres and Wheels” in
chapter 2 for tyre pressure instructions.).
If the pressure is lower or higher than
recommended, drive slowly to the
nearest service station 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
storage locations.

after driving over 50 km if tyres are
replaced. Re-check the tyre wheel
lug nuts after driving over 1,000 km.
CAUTION
Your vehicle has metric threads on
the studs and lug nuts. Make certain
during tyre 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. We recommend that you consult
a HYUNDAI authorised repairer for
assistance.
If any of the equipment such as the jack,
lug nuts, studs, or other equipment is
damaged or in poor condition, do not
attempt to change the tyre and call for
assistance.

Emergency towing
OBC3080019
„Front
„Rear
OBC3080020
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 towing 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.
CAUTION
The driver must be in the vehicle for
steering and braking operations when
the vehicle is being towed. Passengers
other than the driver must not be in the
vehicle.
Always follow these emergency towing
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 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
frequently.
[ 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.

Emergency situations
Automatic accident reporting
OBC3080024
System operation in the event of a traffic accidentConnection with the Public Safety Answering Point(PSAP)
Emergency services
The Pan-European eCall device automatically makes an emergency call to the Public
Safety Answering Point (PSAP) for proper rescuing operations in the event of vehicle
accident.
For proper emergency services and support, the Pan-European eCall system
automatically transmits the accident data to the Public Safety Answering Point (PSAP)
when a traffic accident is detected.
In this case, the emergency call cannot be hung up by pressing the SOS button and
the Pan-European eCall system remains connected until the emergency service
officer, receiving the call, disconnects the emergency call.
In minor traffic accidents, the Pan-European eCall system may not execute an
emergency call. However, an emergency call may be made manually by pressing the
SOS button.
CAUTION
Operation of the system is impossible in case of absence of mobile transmission
and GPS and Galileo signals.

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 indicate 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 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 present.
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.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
WARNING
Do not disconnect and inspect spark
plugs when the engine is hot. You may
burn yourself.
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transmission fluid/iMT
system actuator fluid
(if equipped)
Inspect the Manual transmission fluid/
iMT system actuator fluid according to
the maintenance schedule.

1. Check if the radiator cap label is
straight In front.
2. Make sure that the tiny protrusions
inside the radiator cap should be
securely interlocked.
Recommended engine coolant
[ When adding coolant, use only
distilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. An
incorrect coolant mixture can result
in serious malfunction or engine
damage.
[ The engine in your vehicle has
aluminium 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 specified
coolant.
[ Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the
following table.
