check engine Hyundai Elantra Coupe 2016 Owner's Guide

6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
69
What to do in an emergency
CAUTION
• Serious loss of coolant indi-
cates a leak in the cooling
system and have the system
checked by an authorized
HYUNDAI dealer.
• When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.

Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly. The TPMS mal-
function indicator is combined with
the low tire pressure telltale. When
the system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction
indicator is illuminated, the system
may not be able to detect or signal
low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or alter-
nate tires or wheels on the vehicle
that prevent the TPMS from function-
ing properly. Always check the TPMS
malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replace-
ment or alternate tires and wheels
allow the TPMS to continue to func-
tion properly.✽NOTICE
If the TPMS Low Tire Pressure
Telltale does not illuminate for three
seconds when the ignition switch is
in the ON position or when the
engine starts, or if it remains illumi-
nated after coming on for approxi-
mately three seconds, take your
vehicle to your nearest authorized
HYUNDAI dealer and have the sys-
tem checked.
Low Tire Pressure
Telltale
The TPMS is not a substitute for
manually checking tire pressure with
a tire pressure gauge. Changes in
temperature affect tire pressure. See
“Tires and Wheels” in chapter 7 for
proper tire inflating and tire pressure
measurement procedures.
If the telltale illuminates, immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible.
Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side door
jamb. If you cannot reach a service
station or if the tire cannot hold the
newly added air, replace the low
pressure tire with the spare tire.

What to do in an emergency
Using the Tire Mobility Kit
1.Detach the speed restriction label
(0) from the sealant bottle (1), and
place it in a highly visible place
inside the vehicle such as on the
steering wheel to remind the driver
not to drive too fast.
2.Screw connection hose (9) onto
the connector of the sealant bottle.
3.Ensure that screw cap (8) is
closed.
4.Unscrew the valve cap from the
valve of the flat tire and screw fill-
ing hose (2) of the sealant bottle
onto the valve.
5.Insert the sealant bottle into the
housing (4) of the compressor so
that the bottle is upright.6.Ensure that the compressor is
switched off, position 0.
7.Plug the compressor power cord
into the vehicle power outlet.
8.With the engine start/stop button
position on or ignition switch posi-
tion on, switch on the compressor
and let it run for approximately 5~7
minutes to fill the sealant up to
proper pressure. (refer to the Tire
and Wheels, chapter 8). The infla-
tion pressure of the tire after filling
is unimportant and will be
checked/corrected later.
Be careful not to overinflate the tire
and stay away from the tire when
filling it.9. Switch off the compressor.
10. Detach the hoses from the
sealant bottle connector and
from the tire valve.
Return the Tire Mobility Kit to its stor-
age location in the vehicle.

below 200 kpa (29 psi). This
could result in an accident due
to sudden tire failure.
WARNING - Carbon
monoxide
Do not leave your vehicle run-
ning in a poorly ventilated area
for extended periods of time.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an authorized
HYUNDAI dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labor, parts and lubricants used.
WARNING
Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an author-
ized HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance work:
• Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transaxle vehicle) position or
neutral (for manual transaxle
vehicle, apply the parking
brake, place the ignition
switch in the OFF position.
• Block the tires (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
(Continued)
(Continued)
• If you must run the engine
during maintenance, do so
outdoors or in an area with
plenty of ventilation.
• Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check 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 transaxle occurs,
check the transaxle fluid level.
• Check the automatic transaxle 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 flash-
ers.
• 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.
WARNING
Be careful when checking your
engine 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.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently. After
installing a new filter, run the engine
for several minutes, and check for
leaks at the connections. Fuel filters
should be installed by an authorized
HYUNDAI dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure a new vapor
hose or fuel filler cap is correctly
replaced.

721
Maintenance
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
