2017 KIA OPTIMA PLUG-IN HYBRID engine water pump

SPECIAL DRIVING CONDITIONS
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice, mud, sand, or similar hazards, follow
these suggestions: • Drive cautiously and allow extra dis‐ tance for braking.
• Avoid sudden braking or steering.
• When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is stopped.
WARNING
nABS
Do not pump the brake pedal on avehicle equipped with ABS.
• If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
• Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide traction when
stalled in ice, snow, or mud.
WARNING
nDownshifting
Downshifting with an automatictransaxle, while driving on slipperysurfaces can cause an accident. Thesudden change in tire speed couldcause the tires to skid. Be carefulwhen downshifting on slippery sur‐faces.
Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn the steering wheel right and left
to clear the area around your front
wheels. Then, shift back and forth be‐ tween 1 (First) and R (Reverse) in vehi‐
cles equipped with a manual transaxle
or R (Reverse) and any forward gear in vehicles equipped with an Automatic
Transaxle / Dual clutch transmission. Do
not race the engine, and spin the wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possible
damage to the transaxle.
CAUTION
Prolonged rocking may cause engineover-heating, transaxle damage orfailure, and tire damage.
WARNING
nSpinning tires
Do not spin the wheels, especially atspeeds more than 56 km/h(35 mph). Spinning the wheels athigh speeds when the vehicle is sta‐tionary could cause a tire to over‐heat which could result in tire dam‐age that may injure bystanders.
NOTICE
The ESC system should be turned
OFF prior to rocking the vehicle.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a loss of power, or hear loud pinging or knock‐
ing, the engine is probably too hot. If
this happens, you should: 1. Turn on the emergency warning flasher and stop in a safe place.
Move the shift lever to P (Park) and
engage the parking brake.
2. If hot steam does not come out from the engine room, carefullyopen the engine room and check
whether the water pump connector
is properly engaged. If the connec‐
tor is not properly engaged, stop
the engine immediately and prop‐
erly engage the connector. Then,
turn the engine on.
3. Turn on the air conditioner.
4. If the L

COOLANT
The high-pressure cooling system has
a reservoir filled with year round anti‐
freeze coolant. The reservoir is filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and be‐ fore traveling to a colder climate.
CAUTION
•When the engine overheats fromlow engine coolant, suddenly add‐ing engine coolant may causecracks in the engine. To preventdamage, add engine coolant slowlyin small quantities.
•Do not drive with no engine cool‐ant. It may cause water pump fail‐ure and engine seizure, etc.
Checking the coolant level
WARNING
nRemoving radiator cap
•Never attempt to remove the radi‐ator cap while the engine is oper‐ating or hot. Doing so might leadto cooling system and engine dam‐age. Also, hot coolant or steamcould cause serious personal in‐jury.
•Turn the engine off and wait untilit cools down. Use extreme carewhen removing the radiator cap.Wrap a thick towel around it, andturn it counterclockwise slowly tothe first stop. Step back while thepressure is released from the cool‐ing system.When you are sure all the pressurehas been released, press down onthe cap, using a thick towel, andcontinue turning counterclockwiseto remove it.

(Continued)
•Even if the engine is not operating,do not remove the radiator cap orthe drain plug while the engine andradiator are hot. Hot coolant andsteam may still blow out underpressure, causing serious injury.
The engine coolant and/or inverter
coolant level is influenced by the hybrid system temperature. Before checking
or refilling the engine coolant and/or in‐
verter coolant, turn the hybrid vehicle off.
WARNING
The electric motor (cool‐ing fan) is controlled byengine coolant tempera‐ture, refrigerant pressureand vehicle speed. It maysometimes operate evenwhen the engine is notrunning.
