Instrument cluster
If the brake fluid level in the reser-
voir is low:
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 (For more details,
refer to “Brake Fluid” in chapter 9).
Then check all brake components for
fluid leaks. If any leak on 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, we recommend that
you have the vehicle towed to an
authorized HYUNDAI 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 systems 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 driving,
shift to a lower gear for additional
engine braking and stop the vehicle as
soon as it is safe to do so.
WARNING

Light
Driving the vehicle with a warning light
ON is dangerous. If the Parking Brake &
Brake Fluid Warning Light illuminates

In this case, we recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
