(for smart key system)
This warning message is displayed if
you try to start the engine with the
shift lever not in the P (Park) position.
Low Washer Fluid (if equipped)
This warning message is displayed
if the washer fluid level in the reser-
voir is nearly empty.
Have the washer fluid reservoir
refilled.
Low Fuel
This warning message is displayed if
the fuel tank is almost out of fuel.
When this message is displayed, the
low fuel level warning light in the
cluster will come on.
It is recommended to look for the
nearest fuelling station and refuel as
soon as possible.
Add fuel as soon as possible.
Engine has overheated
This warning message is displayed
when the engine coolant tempera-
ture 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" in chapter 6.

What to do in an emergency
6
7. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
8. Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
we recommend that you call an
authorised HYUNDAI dealer for
assistance.
Serious loss of coolant indi-
cates a leak in the cooling
system and we recommend
the system be checked by an
authorised HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.
CAUTION
Never remove the
engine coolant cap
and/or inverter coolant
cap or the drain plug
whilst the engine and
radiator are hot. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the hybrid system off and
wait until the engine cools down.
Use extreme care when remov-
ing the engine coolant cap
and/or inverter coolant cap.
Wrap a thick towel around it, and
turn it anticlockwise slowly to
the first stop. Step back whilst
the pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning anticlockwise to remove
it.

Maintenance
Owner maintenance schedule
When you stop for fuel:
 Check the engine oil level.
 Check the 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 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 transmission
occurs, check the transmission
fluid level.
 Check the 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).
At least monthly:
 Check coolant level in the engine
coolant reservoir.
 Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
 Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
 Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
 Check radiator, heater and air condi-
tioning hoses for leaks or damage.
 Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
 Check headlamp alignment.
 Check muffler, exhaust pipes,
shields and clamps.
 Check the seat belts for wear and
function. Be careful when checking your
engine coolant/inverter 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.

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.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel lines, fuel hoses and con-
nections 
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend an authorised
HYUNDAI dealer replace any dam-
aged or leaking parts immediately.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorised
HYUNDAI dealer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapour
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs 
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
