brake pads KIA OPTIMA PLUG-IN HYBRID 2017 Owners Manual

BRAKE SYSTEM
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through nor‐ mal usage.
If the hybrid system is not on or is
turned off while driving, the power as‐
sist for the brakes will not work. You can still stop your vehicle by applying
greater force to the brake pedal than
typical. The stopping distance, however,will be longer than with power brakes.
When the hybrid system is not on, the reserve brake power is partially deple‐
ted each time the brake pedal is ap‐
plied. Do not pump the brake pedal when the power assist has been inter‐
rupted.
Pump the brake pedal only when nec‐
essary to maintain steering control on slippery surfaces.
WARNING

•Do not drive with your foot restingon the brake pedal. This will createabnormal high brake tempera‐tures, excessive brake lining andpad wear, and increased stoppingdistances.
•When descending a long or steephill, shift to a lower gear and avoidcontinuous application of thebrakes. Continuous brake applica‐tion will cause the brakes to over‐heat and could result in a tempo‐rary loss of braking performance.
•Wet brakes may impair the vehi‐cle’s ability to safely slow down;the vehicle may also pull to oneside when the brakes are applied.Applying the brakes lightly will in‐dicate whether they have been af‐fected in this way.Always test your brakes in thisfashion after driving through deepwater. To dry the brakes, applythem lightly while maintaining asafe forward speed until brakeperformance returns to normal.
(Continued)
(Continued)
•Always confirm the position of thebrake and accelerator pedal beforedriving. If you don’t check the posi‐tion of the accelerator and brakepedal before driving, you may de‐press the accelerator instead ofthe brake pedal. It may cause a se‐rious accident.
NOTICE
Do not depress the brake pedal con‐
tinuously without the "" indicator
ON. The battery may be discharged.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear a high-pitched warning sound from your
front brakes or rear brakes (if equip‐
ped). You may hear this sound come and go or it may occur whenever you
depress the brake pedal.

Driving your vehicle

Please remember that some driving
conditions or climates may cause a brake squeal when you first apply (or
lightly apply) the brakes. This is normal
and does not indicate a problem with your brakes.
CAUTION
•To avoid costly brake repairs, donot continue to drive with wornbrake pads.
•Always replace the front or rearbrake pads as pairs.
WARNING
nBrake wear
This brake wear warning soundmeans your vehicle needs service. Ifyou ignore this audible warning, youwill eventually lose braking perform‐ance, which could lead to a seriousaccident.
Foot parking brake
Applying the parking brake
0:',
To engage the parking brake, first apply
the foot brake and then depress the
parking brake pedal down as far as possible.
CAUTION
•Driving with the parking brake ap‐plied will cause excessive brakepad (or lining) and brake rotorwear.
(Continued)
(Continued)
•Do not operate the parking brakewhile the vehicle is moving exceptin an emergency situation. It coulddamage the vehicle system andmake endanger driving safety.
Releasing the parking brake
To release the parking brake, depress
the parking brake pedal a second time while applying the foot brake. The ped‐
al will automatically extend to the fully
released position.
