2018 Hyundai Elantra air conditioning

6-6
What to do in an emergency
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine may be overheating. If this hap-
pens, you should:
1. Pull off the road and stop as soon asit is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake. If the air condi-
tioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is coming out
from the hood, stop the engine. Do not
open the hood until the coolant has
stopped running or the steaming has
stopped. If there is no visible loss of
engine coolant and no steam, leave
the engine running and check to be
sure the engine cooling fan is operat-
ing. If the fan is not running, turn the
engine off. 4. Check for coolant leaking from the
radiator, hoses or under the vehicle. (If
the air conditioning had been in use, it
is normal for cold water to be draining
from it when you stop.)
5. If engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal.
Then, if coolant has been lost, careful-
ly add coolant to the reservoir to bring
the fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.

While the engine is run-
ning, keep hands, cloth-
ing and tools away from
the moving parts such
as the cooling fan and
drive belt to prevent
serious injury.
WARNING
Your vehicle is
equipped with a pres-
surized coolant reserve
tank. NEVER remove
the coolant reserve tank
cap or the radiator drain plug while
the engine and radiator are HOT.
Hot coolant and steam may blow
out under pressure, causing seri-
ous injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
coolant reserve tank cap. Wrap a
towel or thick rag around it, and
turn it counterclockwise slowly to
release some of the pressure from
the system. Step back while the
pressure is released.
(Continued)
(Continued)
When you are sure all the pressure
has been released, continue turn-
ing the cap counterclockwise to
remove it.
WARNING
Serious loss of coolant indicates a
leak in the cooling system and
should be checked as soon as pos-
sible by an authorized HYUNDAI
dealer.
CAUTION

Maintenance
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights, 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 Fall)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlamp alignment.
Check muffler, exhaust pipes, shields and clamps.
Check the seat belts for wear and func- tion.
At least once a year:
Clean body and door drain holes.
Lubricate door hinges and hoodhinges.
Lubricate door and hood locks and latches.
Lubricate door rubber weather strips.
Lubricate door checker.
Check the air conditioning system.
Inspect and lubricate automatic trans- mission linkage and controls.
Clean the battery and terminals.
Check the brake fluid level. Follow Normal Maintenance Schedule if
the vehicle is usually operated where
none of the following conditions apply. If
any of the following conditions apply, you
must follow the Maintenance Under
Severe Usage Conditions.
Repeated short distance driving.
Driving in dusty conditions or sandy
areas.
Extensive use of brakes.
Driving in areas where salt or other corrosive materials are used.
Driving on rough or muddy roads.
Driving in mountainous areas.
Extended periods of idling or low speed operation.
Driving for a prolonged period in cold temperatures and/or extremely humid

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).

Tire Terminology and
Definitions
Air Pressure
The amount of air inside the tire
pressing outward on the tire. Air
pressure is expressed in pounds per
square inch (psi) or kilopascal (kPa).
Accessory Weight
This means the combined weight of
optional accessories. Some exam-
ples of optional accessories are
automatic transmission, power
seats, and air conditioning.
Aspect Ratio
The relationship of a tire's height to
its width.
Belt
A rubber coated layer of cords that is
located between the plies and the
tread. Cords may be made from steel
or other reinforcing materials.
Bead
The tire bead contains steel wires
wrapped by steel cords that hold the
tire onto the rim.
Bias Ply Tire
A pneumatic tire in which the plies
are laid at alternate angles less than
90 degrees to the centerline of the
tread.
Cold Tire Pressure
The amount of air pressure in a tire,
measured in pounds per square inch
(psi) or kilopascals (kPa) before a tire
has built up heat from driving.
Curb Weight
This means the weight of a motor
vehicle with standard and optional
equipment including the maximum
capacity of fuel, oil and coolant, but
without passengers and cargo.
DOT Markings
A code molded into the sidewall of a
tire signifying that the tire is in com-
pliance with the U.S. Department of
Transportation motor vehicle safety
standards. The DOT code includes
the Tire Identification Number (TIN),
an alphanumeric designator which
can also identify the tire manufactur-
er, production plant, brand and date
of production.
