steering KIA OPTIMA PLUG-IN HYBRID 2017 Manual PDF

If towing is necessary, we recommendyou to have it done by an authorizedKia dealer or a commercial tow truckservice.
If towing service is not available in an
emergency, your vehicle may be tem‐ porarily towed using a cable or chain
secured to the emergency towing hook
under the front (or rear) of the vehicle. Use extreme caution when towing the
vehicle. A driver must be in the vehicle
to steer it and operate the brakes.
Towing in this manner may be done on‐ ly on hard-surfaced roads for a short
distance and at low speed. Also, the
wheels, axles, power train, steering and brakes must all be in good condition. • Do not use the tow hooks to pull a vehicle out of mud, sand or other
conditions from which the vehicle
cannot be driven out under its own
power.
• Avoid towing a vehicle heavier than the vehicle doing the towing.
• The drivers of both vehicles should communicate with each other fre‐
quently.
CAUTION
•Attach a towing strap to the towhook.
•Using a portion of the vehicle oth‐er than the tow hooks for towingmay damage the body of your ve‐hicle.
•Use only a cable or chain specifi‐cally intended for use in towingvehicles. Securely fasten the cableor chain to the towing hook provi‐ded.
• Before emergency towing, check if the hook is not broken or damaged.
• Fasten the towing cable or chain se‐ curely to the hook.
• Do not jerk the hook. Apply it steadily and with even force.
• To avoid damaging the hook, do not pull from the side or at a vertical an‐
gle. Always pull straight ahead.
WARNING
Use extreme caution when towingthe vehicle.•Avoid sudden starts or erratic driv‐ing maneuvers which would placeexcessive stress on the emergencytowing hook and towing cable orchain. The hook and towing cableor chain may break and cause seri‐ous injury or damage.
•If the disabled vehicle is unable tobe moved, do not forcibly continuethe towing. We recommend thatyou contact an authorized Kiadealer or a commercial tow truckservice for assistance.
•Tow the vehicle as straight aheadas possible.
•Keep away from the vehicle duringtowing.

What to do in an emergency

• Use a towing strap less than 5 m(16 feet) long. Attach a white or red
cloth (about 30 cm (12 inches) wide) in the middle of the strap for easy
visibility.
• Drive carefully so that the towing strap is not loosened during towing.
Emergency towing precautions
• Turn the ignition switch to ACC so thesteering wheel isn’t locked.
• Place the transaxle shift lever in N (Neutral).
• Release the parking bake. • Press the brake pedal with more
force than normal since you will have
reduced brake performance.
• More steering effort will be required because the power steering system
will be disabled.
• If you are driving down a long hill, the brakes may overheat and brake per‐formance will be reduced. Stop often
and let the brakes cool off.
CAUTION
nAutomatic transaxle
•If the car is being towed with allfour wheels on the ground, it canbe towed only from the front. Besure that the transaxle is in neu‐tral. Be sure the steering is un‐locked by placing the ignitionswitch in the ACC position. A drivermust be in the towed vehicle tooperate the steering and brakes.
•To avoid serious damage to theautomatic transaxle, limit the ve‐hicle speed to 15 km/h (10 mph)and drive less than 1.5 km (1 mile)when towing.
(Continued)
(Continued)
•Before towing, check the auto‐matic transaxle for fluid leaks un‐der your vehicle. If the automatictransaxle fluid is leaking, flatbedequipment or a towing dolly mustbe used.

Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check the coolant level in the coolant reservoir.
• Check the windshield washer fluid level.
• Look for low or under-inflated tires.
WARNING
Be careful when checking your en‐gine coolant level when the engine ishot. Scalding hot coolant and steam

may blow out under pressure. Thiscould cause burns or other seriousinjury.
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 any increased steering
effort or looseness in the steering
wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly turns slightly or L

NOTICE
We recommend that when replacing
tires, use the same originally sup‐
plied with the vehicles.
If not, that affects driving perform‐
ance.
CAUTION
When replacing the tires, recheckand tighten the wheel nuts afterdriving about 50 km (31 miles) andrecheck after driving about 1,000 km(620 miles).If the steering wheel shakes or thevehicle vibrates while driving, thetire is out of balance. Align the tirebalance. If the problem is not solved,we recommend that you contact anauthorized Kia dealer.
WARNING
nReplacing tires
(Continued)
(Continued)
To reduce the chance of serious orfatal injuries from an accidentcaused by tire failure or loss of vehi‐cle control:•Replace tires that are worn, showuneven wear, or are damaged.Worn tires can cause loss of brak‐ing effectiveness, steering control,and traction.
•Do not drive your vehicle with toolittle or too much pressure in yourtires. This can lead to uneven wearand tire failure.
•When replacing tires, never mix ra‐dial and bias-ply tires on the samecar. You must replace all tires (in‐cluding the spare) if moving fromradial to bias-ply tires.
•Using tires and wheels other thanthe recommended sizes couldcause unusual handling character‐istics and poor vehicle control, re‐sulting in a serious accident.
(Continued)
(Continued)
•Wheels that do not meet Kia’sspecifications may fit poorly andresult in damage to the vehicle orunusual handling and poor vehiclecontrol.
•The ABS works by comparing thespeed of the wheels. The tire sizeaffects wheel speed. When replac‐ing tires, all 4 tires must use thesame size originally supplied withthe vehicle. Using tires of a differ‐ent size can cause the ABS (Anti-lock Brake System) and ESC (Elec‐tronic Stability Control) to work ir‐regularly.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new wheels are equivalent to the original factory
units in diameter, rim width and offset.
WARNING
A wheel that is not the correct sizemay adversely affect wheel and
