If the brake fluid level in the reser-

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-

With only one of the dual systems
working, more than normal pedal
travel and greater pedal pressure is
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.Parking Brake & Brake Fluid

ing light ON is dangerous. If the
Parking Brake & Brake Fluid
