Fuel gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given inchapter 8.
• The fuel gauge is supplemented by a low fuel warning light, which will
illuminate when the fuel tank is
nearly empty.
• On inclines or curves, the fuel gauge pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank. Avoid driving with a extremely low
fuel level. Running out of fuel
could cause the engine to misfire
damaging the catalytic converter.
NOTICE
i
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pressure
and could severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.
WARNING
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addi-
tional fuel as soon as possible
after the warning light comes
on or when the gauge indicator
comes close to the "0" level.

Engine Oil PressureWarning Light
This warning light illuminates:
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 an
authorized HYUNDAI dealer 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 while 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 authorized HYUNDAI dealer.
Low Fuel LevelWarning Light
This warning light illuminates:
When the fuel tank is nearly empty.
Add fuel as soon as possible.
Driving with the Low Fuel Level
warning light on or with the fuel
level below “0” can cause the
engine to misfire and damage the
catalytic converter (if equipped).

Fuel Filter WarningLight (Diesel Engine)
This warning light illuminates:
• When water has accumulated
inside the fuel filter.
In this case, remove the water from
the fuel filter.
For more details, refer to "Fuel
Filter" in chapter 7.
• When the Fuel Filter Warning Light illuminates, engine power
(vehicle speed & idle speed) may
decrease.
If you keep driving with the warn- ing light on, engine parts (injec-
tor, common rail, high pressure
fuel pump) may be damaged. If
this occurs, we recommend that
you have the vehicle inspected
by an authorized HYUNDAI deal-
er as soon as possible.
Exhaust System (DPF)Warning Light (DieselEngine)
This warning light illuminates:
When there is a malfunction with
Diesel Particulate Filter (DPF) sys-
tem.
When this warning light illumi-
nates, it may turn off after driving
the vehicle:
- at more than 60 km/h (37 mph), or
- at more than 2nd gear with 1500~ 2500 engine rpm for a certain
time (for about 25 minutes).
If this warning light blinks in spite of
the procedure (at this time LCD
warning message will be displayed),
we recommend that you have the
DPF system checked by an author-
ized HYUNDAI dealer.
If you continue to drive with the
DPF warning light blinking for a
long time, the DPF system can be
damaged and fuel consumption
can worsen.
Glow Indicator Light (Diesel Engine)
This indicator light illuminates:
When the engine is being preheat-
ed with the ignition switch or
Engine Start/Stop Button in the ON
position.
- The engine can be started afterthe glow indicator light goes off.
- The illumination time varies with the engine coolant temperature,
air temperature, and battery con-
dition.
If the indicator light remains on or
blinks after the engine has warmed
up or while driving, there may a mal-
function with the engine preheating
system.
In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.

Driving your vehicle
The ISG system is to reduce the fuel
consumption by automatically shut-
ting down the engine, when the vehi-
cle is at a standstill (i.e. red stop light,
stop sign, and traffic jam).
The engine is automatically started
upon satisfying the starting condi-
tions.
The ISG system is always active,
when the engine is running.
Information
When the engine is automatically
started by the ISG system, some warn-
ing lights (i.e. ABS, ESC, ESC OFF,
EPS, and parking brake warning
light) may illuminate for a few sec-
onds due to the low battery voltage.
However, it does not indicate a mal-
function with the ISG system.
To activate the ISG system
Prerequisite for activation
The ISG system operates in the fol-
lowing situations.
- The driver's seatbelt is fastened.
- The driver's door and the hood are closed.
- The brake vacuum pressure is adequate.
- The battery is sufficiently charged.
- The outside temperature is between -10 °C and 35 °C (14 °F and 95 °F).
- The engine coolant temperature is not too low.
- The system is not in the diagnostic mode.
- The steering wheel is not steered excessively. (for dual clutch trans-
mission vehicle)
- The vehicle is driven on a steep incline. (for dual clutch transmis-
sion vehicle)
Information
• The ISG system is not activated,when the prerequisites to activate
the ISG system are unsatisfied. In
this case, the ISG OFF button indi-
cator illuminates, and the auto stop
indicator ( ) illuminates in yellow
on the instrument cluster.
• When the above indicator remains illuminated on the instrument clus-
ter, we recommend you to have the
IGS system checked by an author-
ized HYUNDAI dealer.

Driving your vehicle
5
If you believe your brakes may bewet, apply them lightly while 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 tire tread
decreases, refer to "Tire Tread" 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 while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
fail the braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the high-
way 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.

What to do in an emergency

The displayed tire pressure valuesmay differ from those measured
with a tire pressure gauge.
You can change the tire pressure unit in the User Settings mode on
the instrument cluster.
- psi, kpa, bar (Refer to "LCD
Modes" in chapter 3).Tire pressure monitoring sys-
tem
Each tire, 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 tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of your
tires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-
cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces
fuel efficiency and tire tread life, and
may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-
bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.
Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
WARNING

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While 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
traveling 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 transmission/ 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 while running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pressure
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 implement-
ed with the artificial cardiac
pacemaker, should remain away
from the ECU or the wiring har-
ness by at least 30 cm, while run-
ning the diesel engine. The high
currents of the electric engine
control system produce a con-
siderable amount of magnetic
fields.

Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution rec-
ommended for your vehicle.
All specifications (sizes and pressures)
can be found on a label attached to the
driver’s side center pillar.
(Continued)Replace tires that are worn,
show uneven wear, or are dam-
aged. Worn tires can cause
loss of braking effectiveness,
steering) control, or traction.
ALWAYS replace tires with the
same size as each tire that
was originally supplied with
this vehicle. Using tires and
wheels other than the recom-
mended sizes could cause
unusual handling characteris-
tics, poor vehicle control, or
negatively affect your vehi-
cle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.
Tire failure may cause loss of
vehicle control resulting in an
accident. To reduce risk of
SERIOUS INJURY or DEATH,
take the following precautions:
Inspect your tires monthly for
proper inflation as well as
wear and damage.
The recommended cold tire
pressure for your vehicle can
be found in this manual and on
the tire label located on the dri-
ver’s side center pillar. Always
use a tire pressure gauge to
measure tire pressure. Tires
with too much or too little
pressure wear unevenly caus-
ing poor handling.
Check the pressure of the
spare every time you check
the pressure of the other tires
on your vehicle.
