Your vehicle is equipped with dual-diago-
nal 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 greaterpedal pressure are required to stop the
car. 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. To check bulb operation, check whether
the parking brake and brake fluid warninglight illuminates when the engine
start/stop button is in the ON position.Low tire pressure
telltale (if equipped)
The low tire pressure telltale comes on
for 3 seconds after the engine start/stop
button is turned to the ON position.
If the warning light does not come on, or
continuously remains on after coming on
for about 3 seconds when you turned the
engine start/stop button to the ON posi-
tion, the Tire Pressure Monitoring

occurs, have your vehicle checked by an
authorized HYUNDAI dealer as soon as
possible.
These warning lights will also illuminate if
one or more of your tires are significantly
under-inflated. You should stop and

and stop the vehicle. Avoid hard braking
and overcorrecting at the steering wheel.Inflate the tires to the proper pressure as
indicated on the vehicle’s tire informationplacard.

Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the

ly. If this occurs, have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.

If this happens, the system may not mon-
itor the tire pressure. Have the system
checked by an authorized HYUNDAI
dealer as soon as possible.

ing conditions and under normal driving
conditions, the ESP light will remain off.
