Shift button held down
The warning message appears on the
LCD display, when the shift button is
pressed continuously or the shift button
does not properly operate. Clean the
surroundings of gear shift button.
If this message appears again, have
the vehicle inspected by an authorized
HYUNDAI dealer.
Shifter system malfunction
The warning message appears on the
LCD display, when the transmission
or the shift button does not properly
operate in the P (Park) position.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Check shift controls
The warning message appears on the
LCD display, when there is a malfunction
with transmission shift button.
In this case, have the vehicle inspected
by an authorized HYUNDAI dealer.
Good Driving Practices
• Never shift the gear from P (Park) or
N (Neutral) to any other position with
the accelerator pedal depressed.
• Never shift the gear into P (Park) when
the vehicle is in motion.
• Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive). •
Do not shift the gear to N (Neutral)
when driving. Doing so may result
in an accident because of a loss of
engine braking and the transmission
could be damaged.
• Driving uphill or downhill, always shift
to D (Drive) when driving forward or to
R (Reverse) when driving backwards,
and check the gear position indicated
on the cluster before driving. If you
drive in the opposite direction of the
selected gear, the engine will turn
off and a serious accident might be
occurred due to the degraded brake
performance.
• Do not drive with your foot resting
on the brake pedal. Even light, but
consistent pedal pressure can result
in the brakes overheating, brake wear
and possibly even brake failure.
• When driving in the manual shift
mode, slow down before shifting to a
lower gear. Otherwise, the lower gear
may not be engaged if the engine
rpms are outside of the allowable
range.
• Always apply the parking brake when
leaving the vehicle. Do not depend on
placing the transmission in P (Park) to
keep the vehicle from moving.
• Exercise extreme caution when
driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the drive
wheels to lose traction and may cause
loss of vehicle control resulting in an
accident
• Optimum vehicle performance and
economy is obtained by smoothly
depressing and releasing the
accelerator.

BRAKE SYSTEM
Power Brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
If the vehicle is not in the ready (
)
mode or the vehicle is turned off while
driving, the power assist for the brakes
will not work. You can still stop your
vehicle by applying greater force to the
brake pedal than typical. The stopping
distance, however, will be longer than
with power brakes.
When the vehicle is not in the ready
(
) mode, the reserve brake power is
partially depleted each time the brake
pedal is applied. Do not pump the brake
pedal when the power assist has been
interrupted.
WARNING
Take the following precautions:
• Do not drive with your foot resting
on the brake pedal. This will create
abnormal high brake temperatures,
excessive brake lining and pad wear,
and increased stopping distances.
• When descending down a long or
steep hill, move the gear shift button
to Manual Shift Mode and manually
downshift to a lower gear in order
to control your speed without using
the brake pedal excessively. Applying
the brakes continuously will cause
the brakes to overheat and could
result in a temporary loss of braking
performance.
• Wet brakes may impair the vehicle'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, lightly tap the brake pedal to
heat up the brakes while maintaining
a safe forward speed until brake
performance returns to normal.
Avoid driving at high speeds until the
brakes function correctly.
NOTICE
• Do not continue depressing the
brake pedal if the "" indicator is OFF. The battery may be discharged.
• Noise and vibration generated
during braking is normal.
• Under normal operation, electric
brake pump noise and motor
vibration may occur temporarily in
below cases.
-When the pedal is depressed
suddenly.
-When the pedal is repeatedly
depressed in short intervals.
-When the ABS function is activated
while braking.

Disc Brakes Wear Indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.
Electronic Parking Brake (EPB)
Applying the parking brake
ODN8069012
To apply the EPB (Electronic Parking
Brake):
1. Depress the brake pedal.
2. Pull up the EPB switch.
Make sure the parking brake warning light comes on.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH, do not operate the EPB
while the vehicle is moving except
in an emergency situation. It could
damage the brake system and lead to
an accident.

06
6-27
Anti-lock Brake System (ABS)
WARNING
An Anti-Lock Braking System (ABS) or
an Electronic Stability Control (ESC)
system will not prevent accidents
due to improper or dangerous driving
maneuvers. Even though vehicle
control is improved during emergency
braking, always maintain a safe
distance between you and objects
ahead of you. Vehicle speeds should
always be reduced during extreme
road conditions. The braking distance
for cars equipped with ABS or ESC
may be longer than for those without
these systems in the following road
conditions.
Drive your vehicle at reduced speeds
during the following conditions:
• Rough, gravel or snow-covered
roads.
• On roads where the road surface is
pitted or has different surface height.
• Tire chains are installed on your
vehicle.
The safety features of an ABS or ESC
equipped vehicle should not be tested
by high speed driving or cornering. This
could endanger the safety of yourself or
others.
ABS is an electronic braking system that
helps prevent a braking skid. ABS allows
the driver to steer and brake at the same
time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your brake
pressure and do not try to pump your
brakes. Depress your brake pedal as hard
as possible.
When you apply your brakes under
conditions which may lock the wheels,
you may hear sounds from the brakes,
or feel a corresponding sensation in the
brake pedal. This is normal and it means
your ABS is active.
ABS does not reduce the time or distance
it takes to stop the vehicle.
Always maintain a safe distance from the
vehicle in front of you.
ABS will not prevent a skid that results
from sudden changes in direction, such
as trying to take a corner too fast or
making a sudden lane change. Always
drive at a safe speed for the road and
weather conditions.
ABS cannot prevent a loss of stability.
Always steer moderately when braking
hard. Severe or sharp steering wheel
movement can still cause your vehicle to
veer into oncoming traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping distance
than for vehicles equipped with a
conventional brake system.
The ABS warning light (
) will stay on
for several seconds after the ignition
switch is in the ON position. During
that time, the ABS will go through self-
diagnosis and the light will go off if
everything is normal. If the light stays on,
you may have a problem with your ABS.
Contact an authorized HYUNDAI dealer
as soon as possible.

While Driving
6-28
WARNING
If the ABS warning light () is on and
stays on, you may have a problem with
the ABS. Your power brakes will work
normally. To reduce the risk of serious
injury or death, contact your HYUNDAI
dealer as soon as possible.
CAUTION
When you drive on a road having poor
traction, such as an icy road, and apply
your brakes continuously, the ABS will
be active continuously and the ABS
warning light (
) may illuminate. Pull
your car over to a safe place and turn
the engine off.
Restart the engine. If the ABS warning
light is off, then your ABS system is
normal.
Otherwise, you may have a problem
with your ABS system. Contact an
authorized HYUNDAI dealer as soon as
possible.
Information
When you jump start your vehicle because
of a drained battery, the ABS warning
light (
) may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning. Have the battery
recharged before driving the vehicle.
Electronic Stability Control (ESC)
ODN8069018
The Electronic Stability Control (ESC)
system helps to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies
braking pressure to any one of the
vehicle's brakes and intervenes in the
engine management system to assist the
driver with keeping the vehicle on the
intended path. It is not a substitute for
safe driving practices. Always adjust your
speed and driving to the road conditions.
WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will not
prevent accidents.
Excessive speed in turns, abrupt
maneuvers, and hydroplaning on wet
surfaces can result in severe accidents.
