Convenient features of your vehicle
Charging SystemWarning Light
This warning light illuminates:
• Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It remains on until the engine isstarted.
• When there is a malfunction with either the alternator or electrical
charging system.
If there is a malfunction with either
the alternator or electrical charging
system:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the alternator drive belt for looseness
or breakage.
If the belt is adjusted properly,
there may be a problem in the
electrical charging system.
In this case, we recommend that
you have the vehicle inspected by
a HYUNDAI authorised repairer
as soon as possible.
Engine Oil PressureWarning Light
This warning light illuminates:
• Once you set the ignition switch or
the Engine Start/Stop button to the
ON position.
- It remains on until the engine isstarted.
• When the engine oil pressure is low.
If the engine oil pressure is low:
1. Drive carefully to the nearest safe location and stop your vehicle.
2. Turn the engine off and check the engine oil level (For more details,
refer to “Engine Oil” in chapter 7) .
If the level is low, add oil as required.
If the warning light remains on
after adding oil or if oil is not avail-
able, we recommend that you
have the vehicle inspected by a
HYUNDAI authorised repairer as
soon as possible. • If the engine does not stop
immediately after the Engine Oil
Pressure Warning Light is illumi-
nated, severe damage could
result.
• If the warning light stays on whilst the engine is running, it
indicates that there may be seri-
ous engine damage or malfunc-
tion. In this case,
1. Stop the vehicle as soon as it is safe to do so.
2. Turn off the engine and check the oil level. If the oil level is
low, fill the engine oil to the
proper level.
3. Start the engine again. If the warning light stays on after the
engine is started, turn the
engine off immediately. In this
case, we recommend that you
have the vehicle inspected by
a HYUNDAI authorised repair-
e r.

Each symbols and specification on
air conditioning refrigerant label
means as below:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-cant
You can find out which air conditioning
refrigerant is applied to your vehicle on
the label located inside of the bonnet.
Refer to chapter 8 for the location of
the air conditioning refrigerant label.Checking the amount of air con- ditioner refrigerant and com-pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by a HYUNDAI
authorised repairer.
We recommend the air conditioning
system be serviced by a HYUNDAI
authorised repairer.
Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serviced by
trained and certified techni-
cians. It is important that the
correct type and amount of oil
and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal
inju
r y.
WARNING
Vehicles equipped with R-1234yf
Because the refriger-
ant is mildly inflamma-
ble at very high pres-
sure, the air condition-
ing system should only
be serviced by trained
and certified techni-
cians. It is important
that the correct type and amount
of oil and refrigerant is used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

Driving your vehicle
• If you believe your brakes may be wet, apply them lightly whilst driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tyre tread
decreases, refer to "Tyre
Replacement" in chapter 7.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times whilst the vehicle is mov-
ing slowly.
Highway driving
Tyres
Adjust the tyre inflation, as specified.
Under-inflation may overheat or
damage the tyres.
Do not install worn-out or damaged
tyres, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tyres above
the maximum inflation pressure, as
specified on your tyres.
Fuel, engine coolant and engineoil
Driving at a high speed consumes
more fuel than driving at a slow
speed, such as in an urban area. Do
not forget to check both the engine
coolant and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.

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
High-pressure washing
• When using high-pressure washers,make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
• Do not spray the camera, sensors or its surrounding area directly with a
high pressure washer. Shock
applied from high pressure water
may cause the device to not operate
normally.
• Do not bring the nozzle tip close to boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water. • Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits located in
the engine compartment.
• Never allow water or other liquids to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.
Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster. Removing oil, tar, and
similar materials with a spot remover
will usually strip the wax from the fin-
ish. Be sure to re-wax these areas
even if the rest of the vehicle does
not yet need waxing.
• Wiping dust or dirt off the bodywith a dry cloth will scratch the
finish.
• Do not use steel wool, abrasive cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminium parts.
This may result in damage to the
protective coating and cause dis-
colouration or paint deteriora-
tion.
