Engine Oil Pressure
Warning 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 informa-
tion, refer to “Engine Oil” in chap-
ter 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 Level
Warning 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 or E" can cause the
engine to misfire and damage the
catalytic converter (if equipped).

Driving your vehicle
• If you believe your brakes may be
wet, 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 engine
oil
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.

Driving your vehicle
Check battery and cables
Winter temperatures affect battery
performance.Inspect the battery
and cables, as specified in the
chapter 7.The battery charging level
can be checked by an authorized
HYUNDAI dealer or in a service sta-
tion.
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 chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorized HYUNDAI dealer.Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in the chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorized window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorized
HYUNDAI dealer, and most vehicle
accessory outlets. Do not use engine
coolant or other types of anti-freeze
solution, to prevent any damage to
the vehicle paint.

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 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 posi-
tion.
• 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 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
tires including the spare for tires
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 windshield 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
Checking the engine oil level
1. Follow all of the oil manufacturer’s
precautions.
2. Be sure the vehicle is on level
ground in P (Park) with the parking
brake set and the wheels blocked.
3. Turn the engine on and allow the
engine to reach normal operating
temperature.
4. Turn the hybrid system off and
wait about five minutes for the oil
to return to the oil pan.
5. Pull the dipstick out, wipe it clean,
and re-insert it fully.6. Pull the dipstick out again and
check the level. The level should
be between F (Full) and L (Low).
7. If it is near or at L, add enough oil
to bring the level to F.To prevent damage to your engine:
• Do not overfill with engine oil.
Add oil in small quantities and
recheck level to ensure engine
is not overfilled.
• Do not spill engine oil when
adding or changing engine oil.
Use a funnel to help prevent oil
from being spilled on engine
components. Wipe off spilled oil
immediately.

Maintenance
If the level is low, add the specified
brake fluid to the MAX level. The level
will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, we
recommend that the brake system
be checked by an authorized
HYUNDAI dealer.• Do not allow brake fluid to con-
tact the vehicle’s body paint, as
paint damage will result.
• Brake fluid, which has been
exposed to open air for an
extended time should NEVER be
used as its quality cannot be
guaranteed. It should be dis-
posed of properly.
• Do not use the wrong kind of
brake fluid. A few drops of miner-
al based oil, such as engine oil, in
your brake system can damage
brake system parts.
Information
Use only the specified brake fluid
Refer to “Recommended Lubricants
and Capacities” in chapter 8.
Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
i
NOTICE
If the brake system requires fre-
quent additions of fluid this
could indicate a leak in the
brake system. We recommend
that the vehicle be inspected by
an authorized HYUNDAI dealer.
WARNING
Do not allow brake fluid to come
in contact with your eyes. If
brake fluid comes in contact
with your eyes, flush your eyes
with clean water for at least 15
minutes and get immediate
medical attention.
