2018 Hyundai Elantra engine overheat

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)
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.
