- Engine Oil Pressure
Warning Light
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
an authorised HYUNDAI deal-
er.Low Fuel Level
Warning Light
This warning light illuminates:
When the fuel tank is nearly empty.
If the fuel tank is nearly empty:
Add fuel as soon as possible.
- Low Fuel Level
Driving with the Low Fuel Level
warning light on or with the fuel
level below “0 or E” can cause the
engine to misfire and damage the
catalytic converter (if equipped).
Overspeed Warning
Light (if equipped)
This warning light blinks:
When you drive the vehicle over
120 km/h.
- This is to prevent you from driving
your vehicle with overspeed.
- The overspeed warning chime
also sounds for approximately 5
seconds.

4 Wheel Drive (4WD)
Warning Light
(if equipped)
This warning light illuminates:
Once you set the ignition switch or
Engine Start/Stop button to the ON
position.
- It illuminates for approximately 3
seconds and then goes off.
When there is a malfunction with
the 4WD system.
In this case, we recommend that
you have the vehicle inspected by
an authorised HYUNDAI dealer.
Headlight Warning
Light (if equipped)
This warning light illuminates:
If there is a malfunction (burned-
out bulb except LED light or circuit
malfunction) with the exterior lights
(headlight, brake light, fog light,
etc.). In this case, we recommend
that you have your vehicle inspect-
ed by an authorised HYUNDAI
dealer.
Information
Make sure to replace the burned out
bulb with a new one of the same
wattage rating.
If not, this warning message will not
be displayed.
i
Fuel Filter Warning Light
When the Fuel Filter Warning
Light illuminates, engine
power (vehicle speed & idle
speed) may decrease.
If you keep driving with the
warning light on, engine parts
(injector, common rail, high
pressure fuel pump) may be
damaged. If this occurs, we
recommend that you have the
vehicle inspected by an
authorised HYUNDAI dealer
as soon as possible.
CAUTION

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 replace-
ment" 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 engine
oil
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.

What to do in an emergency
Tyre pressure monitoring sys-
tem
Each tyre, including the spare (if pro-
vided), should be checked monthly
when cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tyre inflation pressure label. If
your vehicle has tyres of a different
size than the size indicated on the
vehicle placard or tyre inflation pres-
sure label, you should determine the
proper tyre inflation pressure for
those tyres.As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is significantly under-
inflated. Accordingly, when the low
tyre pressure telltale illuminates, you
should stop and check your tyres as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly under-inflated tyre causes
the tyre to overheat and can lead to
tyre failure. Under-inflation also
reduces fuel efficiency and tyre tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS is not a
substitute for proper tyre mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tyre pres-
sures, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tyre pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tyre pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tyre pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
native tyres or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tyres or wheels on your
vehicle to ensure that the replace-
ment or alternative tyres and wheels
allow the TPMS to continue to func-
tion properly.

Over-inflation or under-inflation
can reduce tyre life, adversely
affect vehicle handling, and
lead to sudden tyre failure that
may cause loss of vehicle con-
trol resulting in an accident.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the engine
coolant 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 posi-
tion.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when travelling on a smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or a “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmis-
sion/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 artifi-
cial 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.
