2. With the engine stopped, check the brake fluid level immediately and
add fluid as required (For more
details, refer to “Brake Fluid” in

fluid, check all brake components
for fluid leaks. If a brake fluid leak is
found, or if the warning light

operate properly, do not drive the
vehicle. We recommend you to

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.
