2016 HYUNDAI GENESIS COUPE ULTIMATE engine coolant

What to do in an emergency
66
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (automat- ic transmission) or neutral (manual
transmission) and set the parking
brake. If the air conditioning is on,
turn it off.
3. If engine coolant is running out under the car or steam is coming
out from underneath the hood,
stop the engine. Do not open the
hood until the coolant has flow
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is missing. If it is not
missing, check to see that it is
tight. If the drive belt seems to be
satisfactory, check for coolant
leaking from the radiator, hoses or
under the car. (If the air condition-
ing had been in use, it is normal
for cold water to be draining from it
when you stop). 5. If the water pump drive belt is bro-
ken or 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
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.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in coolant to be
blown out of the opening and
cause serious burns.
CAUTION
Serious loss of coolant indicatesthere is a leak in the cooling sys-tem and this should be checkedas soon as possible by anauthorized HYUNDAI dealer.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
WARNING- Maintenance work
Performing maintenance work on a vehicle can be danger-
ous. You can be seriously
injured while performing some
maintenance procedures. If
you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an
authorized HYUNDAI dealer.
Working under the hood with the engine running is danger-
ous. It becomes even more
dangerous when you wear
jewelry or loose clothing.
These can become entangled
in moving parts and result in
injury. Therefore, if you must
run the engine while working
under the hood, make certain
that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and
all neckties, scarves, and sim-
ilar loose clothing before get-
ting near the engine or cool-
ing fans.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

Maintenance
67
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
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 automatic transmission P (Park) function.
Check 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 the coolant level in theengine 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.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air conditioning hoses for leaks or
damage.
Check the windshield washer spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.

NORMAL MAINTENANCE SCHEDULE
The following maintenance services must be performed to ensure good emission control and performance. Keep
receipts for all vehicle emission services to protect your warranty. Where both mileage and time are shown, the fre-
quency of service is determined by whichever occurs first.
*
1: Check the engine oil level and leak every 350 miles(500 km) or before starting a long trip.
*
2: The drive belt should be replaced when cracks occur or tension is reduced excessively.
*
3: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are
available from your authorized HYUNDAI dealer
along with information on how to use them. Do not
mix other additives.
*
4: Rear differential oil should be changed anytime they have been submerged in water.
*
5: Fuel filter & Fuel tank air filter are considered to be maintenance free but periodic inspection is recom-
mended for this maintenance schedule depends on
fuel quality. If there are some important safety matters
like fuel flow restriction, surging, loss of power, hard
starting problem etc, replace the fuel filter immediately
regardless of maintenance schedule and consult an
authorized HYUNDAI dealer for details. *
6: When adding coolant, use only deionized water or
soft water for your vehicle and never mix hard water
in the coolant filled at the factory. An improper coolant
mixture can result in serious malfunction or engine
damage.
*
7: Inspect for excessive valve noise and/or engine vibra- tion and adjust if necessary. We recommend that the
system be checked by an authorized HYUNDAI dealer.
