2017 KIA OPTIMA overheating

447
Features of your vehicle
Electric power steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the ignition
switch on. This happens as the sys-
tem performs the EPS system
diagnostics. When the diagnostics
are completed, the steering wheel
will return to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is turned to the ON or
LOCK (OFF) position.
• A motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• If the Electric Power Steering System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer-
ing wheel may become difficult to
control or operate abnormally.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible. (Continued)

Engine Coolant TemperatureGauge
This gauge indicates the tempera-
ture of the engine coolant when the
ignition switch or Engine Start/Stop
button is ON. If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the Engine
Overheats" in chapter 7.
CAUTION - Red zone
Do not operate the engine with-
in the tachometer's RED ZONE.This may cause severe enginedamage.
OJF045104
WARNING - Hot radiator
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

✽ ✽NOTICE
When opening the windows in
humid weather air conditioning may
create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.
Air conditioning system operation tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
Operating the air conditioning sys- tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.CAUTION - Excessive AC
When using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.

Do not use the kickdown mecha-nism to return to normal driving.
Also, temporarily stop the vehicle
at a safe location, when the warn-
ing message illuminates on the
LCD display.
During the first 1,500km (1,000miles), you may feel that the
vehicle may not be smooth when
accelerating at low speed. During
this break-in period, the shift quali-
ty and performance of your new
vehicle is continuously optimized.
Always come to a complete stop before shifting into D (Drive) or R
(Reverse).
Do not put the shift lever in N (Neutral) while driving. The indicator in the instrument clus-
ter displays the shift lever position
when the ignition switch is in the ON
position.
P (Park)
Always come to a complete stop
before shifting into P (Park).
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
The shift lever must be in P (Park)
before turning the engine off.
R (Reverse)
Use this position to drive the vehicle
backward.
N (Neutral)
The wheels and transmission are not
engaged.
Use N (Neutral) if you need to restart
a stalled engine, or if it is necessary
to stop with the engine ON. Shift into
P (Park) if you need to leave your
vehicle for any reason.
Always depress the brake pedal
when you are shifting from N
(Neutral) to another gear.

- Holding the Vehicle Using
Accelerator Pedal
Do not attempt to hold yourvehicle on a hill by applying theaccelerator pedal. This cancause your clutch and transmis-sion to be damaged as a resultof overheating.
WARNING
Shifting into P (Park) while the vehicle is in motion may
cause you to lose control of
the vehicle.
After the vehicle has stopped, always make sure the shift
lever is in P (Park), apply the
parking brake, and turn the
engine off.
Do not use the P (Park) position in place of the parking brake.
CAUTION
Always come to a complete stopbefore shifting into or out of R(Reverse); you may damage thetransmission if you shift into R(Reverse) while the vehicle is inmotion.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extra
distance 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.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the second gear. Accelerate
slowly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non- slip material under the drive
wheels to provide traction when
stalled in ice, snow, or mud.
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 between 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.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with an auto-
matic transaxle while driving on
slippery surfaces. The sudden
change in tire speed could
cause the tires to skid and
result in an accident.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.
JF CAN (ENG) 6.qxp 2016-09-21 11:28 Page 100

6101
Driving your vehicle
The ESC system should be turned
OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration. If
you follow these suggestions, tire
wear will be held to a minimum.
Driving at night
Because night driving presents more
hazards than driving in the daylight,
here are some important tips to
remember:
Slow down and keep more dis-tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
CAUTION- Vehicle rocking
Prolonged rocking may causeengine overheating, transaxledamage or failure, and tire dam-age.
CAUTION- Spinning tires
Do not spin the wheels, espe-cially at speeds more than 56km/h (35 mph). Spinning thewheels at high speeds when thevehicle is stationary couldcause a tire to overheat whichcould result in tire damage thatmay injure bystanders.

Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.
