Driving your vehicle
Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P (Park)
position.
3DUNLQJ
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake, and
place the ignition switch in the LOCK/
OFF position. Take the Key with you
when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust
system are very hot. Keep away from
the exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a
fire.
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. 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 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.

Transmission ranges
The indicator in the instrument cluster
displays the shift lever position when the
ignition switch is in the ON position.
33DUN
Always come to a complete stop before
shifting into P (Park).
To shift from P (Park), you must depress
firmly on the brake pedal and make sure
your foot is off the accelerator 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
chapter.
The shift lever must be in P (Park) before
turning the engine off.
WARNING

[Shifting into P (Park) whilst 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
engine off.

[When parking on an incline, place the
shift lever in P (Park) and apply the
parking brake to prevent the vehicle
from rolling downhill.

[For safety, always engage the parking
brake with the shift lever in the P
(Park) position except for the case of
emergency parking.
55HYHUVH
Use this position to drive the vehicle
backward.
NOTICE
Always come to a complete stop before
shifting into or out of R (Reverse); you
may damage the transmission if you
shift into R (Reverse) whilst the vehicle
is in motion.
11HXWUDO
The wheels and transmission are not
engaged.
Use N (Neutral) if you need to restart
a stalled engine, or if it is necessary to
stop with the engine ON. Shift into P
(Park) if you need to leave your vehicle
for any reason.
Always depress the brake pedal when
you are shifting from N (Neutral) to
another gear.
''ULYH
This is the normal driving position. The
transmission will automatically shift
through a 7-gear sequence, providing
the best fuel economy and power.
For extra power when passing another
vehicle or driving uphill, depress the
accelerator fully. The transmission will
automatically downshift to the next
lower gear (or gears, as appropriate).

6-38
Driving your vehicle
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. We recommend that you contact a
HYUNDAI authorised repairer as soon as
possible.
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, we recommend that
you contact your HYUNDAI dealer as
soon as possible.
NOTICE
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 vehicle 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. We recommend
that you contact a HYUNDAI authorised
repairer as soon as possible.

Hill-Start Assist Control (HAC)
(if equipped)
The Hill-Start Assist Control (HAC)
helps prevent the vehicle from rolling
backwards when starting a vehicle from
a stop on a hill. The system operates the
brakes automatically for approximately
2 seconds and releases the brake after 2
seconds or when the accelerator pedal is
depressed.
WARNING
Always be ready to depress the
accelerator pedal when starting off on
an incline. The HAC activates only for
approximately 2 seconds.
