BRAKE FLUID (IF EQUIPPED)
Checking the brake fluid level
Check the fluid level in the reservoir pe‐
riodically. The fluid level should be be‐ tween MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around the reservoir cap thoroughly to
prevent brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumula‐ ted mileage. This is a normal condition
associated with the wear of the brake
linings. If the fluid level is excessively low, we
recommend that the system be
checked by an authorized Kia dealer.
Use only the specified brake fluid (Re‐
fer to L

PARKING BRAKE (IF EQUIPPED)
Checking the parking brake
0+'
Check whether the stroke is within
specification when the parking brake pedal is depressed with 30 kg (66 lb,
294N) of force. Also, the parking brake
alone should securely hold the vehicle on a fairly steep grade. If the stroke is
more or less than specified, we recom‐
mend that the system be serviced by an authorized Kia dealer.
Stroke : 6~7 notch

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
