2018 Hyundai Elantra SCHEDULE

7-18
Maintenance
Automatic Transmission Fluid
(if equipped)
Automatic transmission fluid should not
be checked under normal usage condi-
tions. But in severe conditions, the fluid
should be changed at an authorized
HYUNDAI dealer in accordance to the
scheduled maintenance at the beginning
of this chapter.
Automatic transmission fluid color is
basically red.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker. This is a normal condition and
you should not judge the need to
replace the fluid based upon the
changed color.
Dual Clutch Transmission
Fluid (if equipped)
Inspect the dual clutch transmission fluid
according to the maintenance schedule.
Manual Transmission Fluid
(if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.
Brake Hoses and Lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake/Clutch Fluid
Check brake/clutch fluid level in the
brake/clutch fluid reservoir. The level
should be between the MIN and the MAX
marks on the side of the reservoir. Use
only hydraulic brake/clutch fluid conform-
ing to DOT 3 or DOT 4 specification.
Parking Brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
Brake Discs, Pads, Calipers
and Rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
Exhaust Pipe and Muffler
Visually inspect the exhaust pipes, muf-
fler and hangers for cracks, deterioration,
or damage. Start the engine and listen
carefully for any exhaust gas leakage.
Tighten connections or replace parts as
necessary.
Suspension Mounting Bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the engine
off, check for excessive free-play in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks, or
damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and con-
nections for leakage and damage.
NOTICE
The use of a non-specified fluid
could result in transmission mal-
function and failure. Use only the
specified automatic transmission
fluid (refer to "Recommended
Lubricants and Capacities" in
chapter 8).
CAUTION

7-20
Maintenance
Use only the specified engine oil
(refer to "Recommended Lubricants
and Capacities" in chapter 8).
Checking the Engine Oil and
Filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule at the begin-
ning of this chapter.
NOTICE
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects and
reproductive harm. Used engine oil
may cause irritation or cancer of
the skin if left in contact with the
skin for prolonged periods of time.
Always protect your skin by wash-
ing your hands thoroughly with
soap and warm water as soon as
possible after handling used oil.

Changing Engine Coolant
Have coolant changed by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the beginning
of this chapter.
To prevent damage to engine parts,
put a thick towel around the radiator
cap before refilling the coolant to pre-
vent the coolant from overflowing into
engine parts, such as the generator.
Checking the Brake/Clutch
Fluid Level
Check the fluid level in the reservoir peri-
odically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap and
adding brake/clutch fluid, clean the area
around the reservoir cap thoroughly to
prevent brake/clutch fluid contamination.
If the level is low, add the specified
brake/clutch fluid to the MAX level. The
level will fall with accumulated mileage.
This is a normal condition associated
with the wear of the brake/clutch linings.
If the fluid level is excessively low, have
the brake/clutch system checked by an
authorized HYUNDAI dealer.
NOTICE
Do not use engine coolant or
antifreeze in the washer fluid reser-
voir.
Engine coolant can severely
obscure visibility when sprayed on
the windshield and may cause loss
of vehicle control resulting in an
accident.
Engine coolant may also cause
damage to paint and body trim.
WARNING
If the brake system requires fre-
quent additions of fluid this could
indicate a leak in the brake system.
Have the vehicle inspected by an
authorized HYUNDAI dealer.
WARNING
Do not allow brake/clutch 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 atten-
tion.

Maintenance
4. Lock the cover with the cover attach-ing clips.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to "Maintenance Under
Severe Usage Conditions" in this chapter).
Do not drive with the air cleaner fil-ter removed. This will result in
excessive engine wear.
When removing the air cleaner filter, be careful that dust or dirt does not
enter the air intake, or damage may
result.
Use HYUNDAI genuine parts, use of non-genuine parts could damage
the air flow sensor.
Filter Inspection
The climate control air filter should be
replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it should
be inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
1. With the glove box open, remove thestoppers on both sides to allow the
glove box to hang freely on the hinges.

Maintenance
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion control system to meet all applicable
emission regulations. There are three
emission control systems, as follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to assure the proper function of
the emission control systems, it is recom-
mended that you have your vehicle
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manual.For the Inspection and Maintenance
Test (With Electronic Stability Control
(ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch (ESC OFF light illumi-
nated).
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.1. Crankcase Emission Control System
The positive crankcase ventilation sys-
tem is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative Emission ControlSystem Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere. The ORVR system is designed to
allow the vapors from the fuel tank to be
loaded into a canister while refueling at
the gas station, preventing the escape of
fuel vapors into the atmosphere.
