Driving your vehicle
Check shift controls
The message appears on the LCD
display when there is problem with
the shift buttons.
We recommend you to immediately
have the vehicle inspected by a
HYUNDAI authorised repairer
Good driving practices
Never shift to P (Park) or N(Neutral) to any other position with
the accelerator pedal depressed.
Never shift to 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 to N (Neutral) when driving. Doing so may result in an
accident.
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.
Always apply the parking brake when leaving the vehicle. Do not
depend on placing the gear 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 whilst 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, use the pad-
dle shifter (left side lever) to
increase regenerative braking
control in order to control
your speed without using the
brake pedal excessively.
Applying the brakes continu-
ously will cause the brakes to
overheat and could result in a
temporary loss of braking per-
formance.
(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 whilst maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.
WARNING

5-20
Driving your vehicle
Do not continue depressing the brake pedal if the " "indica-
tor 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 depressedsuddenly.
- When the pedal is repeatedly depressed in short intervals.
- When the ABS function is acti- vated whilst 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.
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.
Electronic parking brake (EPB)
Applying the parking brake
To apply the EPB (Electronic
Parking Brake):
1. Depress the brake pedal.
2. Pull the EPB switch upwards.
Make sure the Parking Brake
Warning Light comes on.
With the AUTO HOLD feature
enabled, the EPB is automatically
applied when the vehicle is shut off.
However, if the EPB switch is
pressed within 1 second after the
vehicle is turned off, the EPB will not
be applied.

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
POWER 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 normal. If
the light stays on, you may have a
problem with your ABS. We recom-
mend that you contact a HYUNDAI
authorised repairer as soon as pos-
sible.(Continued)
On roads where the road sur-
face is pitted or has different
surface height.
Tyre 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.
