ENGINE OIL
Checking the Engine Oil Level
Engine oil is used for lubricating,
cooling, and operating various hydraulic
components in the engine. Engine oil
consumption while driving is normal,
and it is necessary to check and refill the
engine oil regularly. Also, check and refill
the oil level within the recommended
maintenance schedule to prevent
deterioration of oil performance.
Check the engine oil following the below
procedure.
1. Follow all of the oil manufacturer’s precautions.
2. Be sure the vehicle is on the level ground in P (Park) with the parking
brake set. If possible, block the
wheels.
3. Turn the engine on and allow the engine to reach normal operating
temperature.
4. Turn the engine off and wait about fifteen minutes for the oil to return to
the oil pan.
5. Pull the dipstick out, wipe it clean, and re-insert it fully.

NOTICE
To prevent damage to your engine:
• 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.
• The engine oil consumption may
increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles.
• The engine oil consumption can be
affected by driving habits, climate
conditions, traffic conditions,
oil quality, etc. Therefore, it is
recommended that you inspect the
engine oil level regularly and refill it
if necessary.
Checking the Engine Oil and
Filter
• The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil
and filter changed by an authorized
HYUNDAI dealer according to the
Engine Oil Life Management System
Instructions or the Maintenance
Schedule at the beginning of this
chapter.
• If the maintenance schedule to replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.
• To keep the engine in optimal condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.
• The purpose of the maintenance schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the
factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season and
before traveling to a colder climate.
NOTICE
• When the engine overheats from
low engine coolant, suddenly adding
engine coolant may cause cracks
in the engine. To prevent damage,
add engine coolant slowly in small
quantities.
• Do not drive with no engine coolant.
It may cause water pump failure and
engine seizure, etc.

Checking the Brake/Clutch Fluid
Level
OCN7N091036NOCN7N091036N
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add 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, have
the system be checked by an authorized
HYUNDAI dealer.
Information
Use only the specified brake/clutch fluid.
Refer to “Recommended lubricants and
capacities” in chapter 2.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing. Use
only DOT4 brake/clutch fluid from a
sealed container.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake/clutch
fluid comes in contact with your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE
• Do not allow brake/clutch fluid to
contact the vehicle’s body paint, as
paint damage will result.
• Brake/clutch 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 disposed of properly.
• Don’t put in the wrong kind of fluid. A
few drops of mineralbased oil, such
as engine oil, in your brake system
can damage system parts.
• To maintain the best braking
performance and ABS/ESC
performance, have you use genuine
brake/clutch fluid that conform to
specifications.

Checking the Washer Fluid Level
OCN7N091037NOCN7N091037N
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. Plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
Engine coolant can severely obscure
visibility when sprayed on the
windshield and may cause loss
of vehicle control resulting in an
accident or damage to paint and
body trim.
• Do not allow sparks or flames to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from
children and animals.

WARNING
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 driver’s
side center pillar. Always use a
tire pressure gauge to measure
tire pressure. Tires with too
much or too little pressure wear
unevenly causing poor handling.
• Check the pressure of the
spare every time you check the
pressure of the other tires on
your vehicle.
• Replace tires that are worn, show
uneven wear, or are damaged.
Worn tires can cause loss of
braking effectiveness, steering
control, or traction.
• ALWAYS replace tires with
the same type, size, brand,
construction and tread pattern
as each tire that was originally
supplied with this vehicle. Using
tires and wheels other than the
recommended sizes could cause
unusual handling characteristics,
poor vehicle control, or
negatively affect your vehicle’s
Anti-Lock Brake System (ABS)
resulting in a serious accident.
Information - Power Hop
When fully accelerating the vehicle
from standstill, a front tire oscillation
called “Power Hop“ of Elantra N
may occur due to the high torque
of engine and the characteristics of
high performance tire. This may
be affected by road condition and
temperatures.
Additionally it is a normal phenome
non in powerful front-wheel drive
vehicles. Elantra N will act on this
phenomenon with the traction control
in all ESC modes with the main focus
on high performance character.
