2017 KIA OPTIMA PLUG-IN HYBRID brake

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.

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.
