Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds
- It remains on if the parking brake is applied.
When the parking brake is applied.
When the brake fluid level in the reservoir is low.

indicates the brake fluid level in
reservoir is low. If the brake fluid level in the reservoir
is low:

location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately
and add fluid as required (For
more details, refer to "Brake Fluid"
in chapter 7).
Then check all brake components for fluid leaks. If any leak on the
brake system is still found, the
warning light remains on, or the
brakes do not operate properly, do
not drive the vehicle.
In this case, have your vehicle
towed to an authorized Kia dealer
and inspected.
Dual-diagonal braking system
Your vehicle is equipped with dual-
diagonal braking systems. This
means you still have braking on two
wheels even if one of the dual sys-
tems should fail. With only one of the dual systems
working, more than normal pedal
travel and greater 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 driv-
ing, shift to a lower gear for addition-
al engine braking and stop the vehi-
cle as soon as it is safe to do so.
WARNING - Parking

ing light ON is dangerous. If the
Parking Brake & Brake Fluid
Warning Light illuminates with
the parking brake released, it
indicates that the brake fluid
level is low.

inspected by an authorized Kia
dealer.
