overheated engine. If your vehicle
overheats, refer to "If the Engine
Overheats" in chapter 6.
Fuel Gauge
This gauge indicates the approxi-
mate amount of fuel remaining in the
fuel tank.
Information
• The fuel tank capacity is given in
chapter 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 an extremely
low fuel level. Running out of fuel
could cause the engine to misfire,
damaging the catalytic converter.

Your HYUNDAI vehicle air condition-
ing system is filled with R-1234yf
refrigerant.
1. Start the engine.
2. Press the air conditioning button.
3. Select the Face Level mode.
4. Set the air intake control to the
recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, switch the
air intake control to the outside
(fresh) air position. The indicator
light on the button will turn OFF.
5. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
rotate the temperature control knob
to the left-most position (MAX AC).
Then set the fan speed control knob
to the highest speed.When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
Air conditioning system operation
tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time to
let the hot air inside the vehicle
escape.
After sufficient cooling has been
achieved, switch back from the recir-
culated air to the fresh outside air
position.
To help reduce moisture inside of
the windows on rainy or humid days,
decrease the humidity inside the
vehicle by operating the air condi-
tioning system with the windows and
sunroof closed.
Use the air conditioning system
every month for a few minutes to
ensure maximum system perform-
ance.
If you operate the air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface of the wind-
shield to fog up, causing loss of visi-
bility. In this case, set the mode
selection button to the position
and set the fan speed control knob
to the lowest speed setting.

Power Outlet
The accessory 12V power outlet can
be used to plug in electrical equip-
ment such as a mobile phone or
other electronic device.The accessory power outlet only
works with the vehicle turned ON.
The devices should draw less than
180 W with the engine running.
To prevent damage to the Power
Outlets :
Use the power outlet only when
the engine is running and
remove the accessory plug after
use. Using the accessory plug
for prolonged periods of time
with the engine off could cause
the battery to discharge.
Only use 12V electric acces-
sories which are less than 180 W
in electric capacity. Adjust the air-conditioner or
heater to the lowest operating
level when using the power out-
let.
Close the cover when not in use.
Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static
and malfunctions in other elec-
tronic systems or devices used
in your vehicle.
Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may blow.
Plug in battery equipped electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle’s electri-
cal/electronic system and cause
system malfunction.
NOTICE
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outlet
with a wet hand.

Driving your vehicle
Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the Key
with you when exiting the vehicle.
Good Driving Practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P
(Park) when the vehicle is in
motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not move the shift lever to N
(Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released. When driving in Manual Shift
Mode, slow down before shifting to
a lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake
when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.
5
When you stay in the vehicle
with the engine running, be
careful not to depress the
accelerator pedal for a long
period of time. The engine or
exhaust system may overheat
and start a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.

Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, move the
gear shift lever to Manual
Shift Mode and manually
downshift to a lower gear in
order to control your speed
without using the brake pedal
excessively. Applying the
brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.WARNING

Hazardous driving conditions
When hazardous driving elements
are encountered such as water,
snow, ice, mud and sand, take the
below suggestions:
Drive cautiously and keep a longer
braking distance.
Avoid abrupt braking or steering.
When your vehicle is stuck in snow,
mud, or sand, use second gear.
Accelerate slowly to avoid unnec-
essary wheel spin.
Put sand, rock salt, tire chains or
other non-slip materials under the
wheels to provide additional trac-
tion while the vehicle becomes
stuck in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-
tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.

Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING
If the vehicle is stuck and
excessive wheel spin occurs,
the temperature in the tires can
increase very quickly. If the tires
become damaged, a tire blow
out or tire explosion can occur.
This condition is dangerous -
you and others may be injured.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle.
If you attempt to free the vehicle,
the vehicle can overheat quickly,
possibly causing an engine
compartment fire or other dam-
age. Try to avoid spinning the
wheels as much as possible to
prevent overheating of either the
tires or the engine. DO NOT
allow the vehicle to spin the
wheels above 35 mph (56 km/h).

Information
The ESC system must be turned OFF
before rocking the vehicle.
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid engine overheating, possi-
ble damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
Driving at night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more dis-
tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the
glare from other driver's head-
lamps.
Keep your headlamps clean and
properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head-
lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous. Here are a few things to
consider when driving in the rain or
on slick pavement:
Slow down and allow extra follow-
ing distance. A heavy rainfall
makes it harder to see and increas-
es the distance needed to stop
your vehicle.
Turn OFF your Cruise Control.
Replace your windshield wiper
blades when they show signs of
streaking or missing areas on the
windshield.
Be sure your tires have enough
tread. If your tires do not have
enough tread, making a quick stop
on wet pavement can cause a skid
and possibly lead to an accident.
See "Tire replacement" in chap-
ter 7.
Turn on your headlamps to make it
easier for others to see you.
Driving too fast through large pud-
dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
