Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.

Your vehicle is equipped with dual-diago-
nal braking systems. This means you still

pedal pressure are required to stop the
vehicle. Also, the vehicle will not stop in
as short a distance with only a portion of
the brake system working. If the brakes
fail while you are driving, shift to a lower
gear for additional engine braking and
stop the vehicle as soon as it is safe to do
so. To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.Front fog light indicator

diately by an authorized KIA dealer.
