Brake fluid

G WARNING
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of moisture
from the atmosphere. Under extremely
strenuous operating conditions, this
moisture content can lead to the formation
of bubbles in the system, thus reducing the
system's efficiency.
Therefore, the brake fluid must be replaced
regularly. Refer to your vehicle's
Maintenance Booklet for replacement
interval.
The brake fluid level in the brake fluid
reservoir may be too low if the brake
warning lamp in the instrument cluster
comes on ( page 21) although the parking
Y
brake is released.
! If you find that the brake fluid in the
brake fluid reservoir has fallen to the
minimum mark or below, have the brake
system checked for brake pad thickness
and leaks immediately. Contact an
authorized smart center immediately. Do
not add brake fluid as this will not solve
the problem.
