In The Event Of Brake Failure - Hyundai 2012 Sonata Hybrid Owner's Manual

(Continued)
• Wet brakes may impair the vehi-
cle's ability to safely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
• Always, confirm the position of
the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
• Do not turn off the Hybrid system
while going down a hill. The brake
booster may not work sufficiently
and the braking distance may be
longer.

• If the brake pedal does not return
to its normal position when
released, there may be a malfunc-
tion in the brake system. Take
your vehicle to an authorized
HYUNDAI dealer and have the
system checked.
• To avoid applying the brakes do
not get too close to the vehicle in
front of you and try to avoid
going down steep roads or sharp
corning if the power assisted
brakes are not functioning nor-
mally. The vehicle will stop but
the braking distance may be
longer.
CAUTION
If the driver's door is not firmly
closed for a long time, the auxiliary
battery may be discharged because
the brake controller keeps the
standby operation. To prevent the
battery discharge, close the door
certainly.
Driving your vehicle

In the event of brake failure

If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
WARNING
- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
✽ ✽ NOTICE
1)When you apply the brake repeatedly,
you may hear the sound operating the
electric hydraulic pump or motor
operation. It is normal sound.

the abnormal brake feeling may occur,
however it is normal condition.
- When you apply the pedal quickly

ously and repeatedly
