LCD display for transmission
temperature and warning
message
Steep Grade
This warning message is displayed
when vehicle is driven slowly on a
grade and the vehicle detects that
the brake pedal is not applied.
Driving up hills or on steep grades:
To hold the vehicle on an incline
use the foot brake or the parking
brake.
When in stop-and-go traffic on an
incline, allow a gap to form ahead
of you before moving the vehicle
forward. Then hold the vehicle on
the incline with the foot brake. If the vehicle is held or creeping
forward on an incline by applying
the accelerator pedal, the clutch
and transmission may overheat
which can result in damage. At this
time, a warning message will
appear on the LCD display.
If the LCD display warning is
active, the foot brake must be
applied.
Ignoring the warnings can lead to
damage to the transmission.
To hold the vehicle on a hill use
the foot brake or the parking
brake. If the vehicle is held by
applying the accelerator pedal on
a hill, the clutch and transmission
will be overheated resulting in
damage.

Transmission High Temperature
Under certain conditions, such as
repeated stop-and-go launches on
steep grades, sudden take off or
acceleration, or other harsh driving
conditions, the transmission clutch
temperatures will increase exces-
sively.
When the clutch temperatures are
too high, the "Transmission temp is
high! Stop safely" warning mes-
sage will appear on the LCD dis-
play, a chime will sound, and the
transmission shifting may not be
smooth. If this occurs, pull over to a safe
location, stop the vehicle with the
engine running, apply the brakes
and shift the vehicle to P (Park),
and allow the transmission to cool.
If you ignore this warning, the driv-
ing condition may become worse.
You may experience abrupt shifts,
frequent shifts, or jerkiness.
When the message "Trans cooled.
Resume driving." appears you can
continue to drive your vehicle.
When possible, drive the vehicle
smoothly.
Transmission Overheated
If the vehicle continues to be driv-
en and the clutch temperatures
reach the maximum temperature
limit, the "Transmission Hot! Park
with engine on" warning will be dis-
played. When this occurs the clutch
is disabled until the clutch cools to
normal temperatures.

tem checked.
Shift Lever Position
P (Park)
Always come to a complete stop
before shifting into P (Park).
To shift from P (Park), you must depr
ess firmly on the brake pedal and
make sure your foot is off the accel-
erator pedal.
If you have done all of the above
and still cannot shift the lever out
of P (Park), see "Shift-Lock
Release" in this section.
The shift lever must be in P (Park)
before turning the vehicle off.Shifting into P (Park) while the
vehicle is in motion may
cause you to lose control of
the vehicle.
After the vehicle has stopped,
always make sure the shift
lever is in P (Park), apply the
parking brake, and turn the
vehicle off.
When parking on an incline,
place the shift lever in Park
and apply the parking brake to
prevent the vehicle from
rolling downhill.
Do not use the P (Park) posi-
tion in place of the parking
brake.

Good Driving Practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever 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 move the shift lever to N
(Neutral) when driving. If the shift
lever is moved to N (Neutral) while
driving, the vehicle loses the ability
to provide engine braking. Doing
so may increase the risk of an acci-
dent. Also, moving the shift lever
back to D (Drive) while the vehicle
is moving may severely damage
the transmission.
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. Depressing both accelerator and
brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released.
When driving in 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 transmis-
sion 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.

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.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending down a
long or steep hill, move the
gear shift lever 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 tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
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 fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.

Do not depress the brake pedal
continuously without the " "
indicator ON. The battery may be
discharged.
Some noise and vibration may
occur during braking. This is
normal.
In below cases, some electric
brake pump noise and motor
vibration may occur temporarily.
This is normal operation.
- When the pedal is depressed
very quickly
- When the pedal is depressed
multiple times in short inter-
vals
- When the ABS function is acti-
vated during braking
Disc Brake 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.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information
Always replace brake pads as com-
plete front or rear axle sets.
Parking Brake
(foot type, if equipped)
Always set the parking brake before
leaving the vehicle. To apply the
parking brake:
Firmly depress the brake pedal.
Depress the parking brake pedal
down as far as possible.

Driving your vehicle
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 dis-
tance 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 con-
ditions.ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing 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 sys-
tem 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
Engine Start/Stop button is in the ON
position. During that time, the ABS
will go through self-diagnosis and the
light will go off if everything is nor-
mal. If the light stays on, you may
have a problem with your ABS.
Contact an authorized HYUNDAI
dealer as soon as possible.(Continued)
Drive your vehicle at reduced
speeds during the following
conditions:
Rough, gravel or snow-cov-
ered roads.
On roads where the road sur-
face 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.

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)
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 man-
agement 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.
i
When you drive on a road hav-
ing 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 vehicle
off.
Restart the vehicle. 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.
CAUTION
If the ABS warning light ( ) is
on and stays on, you may have
a problem with the ABS. Your
power brakes will work normal-
ly. To reduce the risk of serious
injury or death, contact your
HYUNDAI dealer as soon as
possible.
