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.
If this occurs, we recommend that
you have the vehicle inspected by a
HYUNDAI authorised repairer as soon
as possible.

NOTICE

[If the engine is not stopped
immediately after the Engine Oil
Pressure Warning Light is illuminated,
severe damage could result.

[If the warning light stays on whilst
the engine is running, it indicates
that there may be serious engine
damage or malfunction. 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 repairer.

Low engine oil (if equipped)
This warning message is displayed when
the engine oil level should be checked.
If this warning message is displayed,
check the engine oil level as soon as
possible and add engine oil as required.
Slowly pour the recommended oil little
by little into a funnel.
Use only the specified engine oil. (Refer
to "Recommended lubricants and
capacities" section in chapter 2.)
Do not overfill the engine oil. Make sure
the oil level is not above F (Full) mark on
the dipstick.
NOTICE
If the message is displayed
continuously after adding the engine
oil and travelling approximately 31~
62 mile (50~100 km) after the engine
warms up, we recommend that the
system be checked by a HYUNDAI
authorised repairer.
Engine has overheated
(if equipped)
This warning message is displayed
when the engine coolant temperature
is above 120°C (248°F). This means that
the engine is overheated and may be
damaged.
If your vehicle is overheated, refer to
“Overheating” section in chapter 8.
Check headlight (if equipped)
This warning message is displayed if the
headlamps are not operating properly.
In addition, if a specific lamp(turn signal
lamp etc.) is not operating properly, the
warning message according to a specific
lamp (turn signal lamp etc.) is displayed.
A corresponding bulb may need to be
replaced.
Make sure to replace the burned out
bulb with a new one of the same
wattage rating.
Check brake light (if equipped)
This warning message is displayed if the
stop lamps are not operating properly. A
lamp may need to be replaced.
Make sure to replace the burned out
bulb with a new one of the same
wattage rating.
Check Active Air Flap system (if
equipped)
This message is displayed in the
following situations:
- There is a malfunction with the
actuator flap
- There is a malfunction with the
actuator air flap controller
- The air flap does not open
When all of the above conditions are
fixed, the warning will disappear.

Driving your vehicle
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 increases as
the depth of tyre tread decreases, refer
to “Tyre replacement” in chapter 9.
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 several
times whilst the vehicle is moving
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.

Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine
coolant level and the engine oil before
driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.

When installing tyre chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tyre chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park
the vehicle on level ground away from
traffic. Turn on the vehicle Hazard
Warning Flasher and place a triangular
emergency warning device behind the
vehicle (if available). Always place the
vehicle in P (Park), apply the parking
brake and turn off the engine before
installing snow chains.
NOTICE
When using tyre chains:

[Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
body and wheels.

[Use SAE “S” class or wire chains.

[If you hear noise caused by chains
contacting the body, retighten the
chain to prevent contact with the
vehicle body.

[To prevent body damage, retighten
the chains after driving 0.3~0.6 miles
(0.5~1.0 km).

[Do not use tyre chains on vehicles
equipped with aluminium wheels. If
unavoidable, use a wire type chain.

[Use wire chains less than 0.47 in (12
mm) wide to prevent damage to the
chain’s connection.
Winter Precautions
Use high quality ethylene glycol coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because it
helps prevent corrosion in the cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule. Before
winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter temperatures affect battery
performance. Inspect the battery and
cables, as specified in the chapter
9. The battery charging level can be
checked by a HYUNDAI authorised
repairer or in a service station.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity. For
further information, refer to the chapter
2. When you are not sure about a type
of winter weight oil, consult a HYUNDAI
authorised repairer.

ENGINE OIL
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption whilst driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.

1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on the level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and warm
the engine up until the coolant
temperature reaches a constant
normal temperature.
4. Turn the engine off, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to
return to the oil pan.
5. Wipe the dipstick clean and re-insert
it fully.
6. Pull the dipstick out again and check
the level. The level should be between
the F-L line.

7. If the oil level is below the L, add
enough oil to bring the level to F.
Use only the specified engine oil (Refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
NOTICE
To prevent damage to your engine:

[Do not spill engine oil when adding or
changing engine oil. Wipe off spilled
oil immediately.

[The engine oil consumption may
increase whilst you break in a new
vehicle and it will be stabilized after
driving 6,000 km (4,000 miles).

[The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it if
necessary.
