Driving your vehicle
The driving mode automaticallychanges to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine braking performance, even when
you release the accelerator pedal
in SMART SPORT mode. It is
because your vehicle remains in
lower gear over a certain period of
time for next acceleration. Thus, it
is a normal driving situation, not
indicating any malfunction.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART NORMAL mode.Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves theshift lever :
It deactivates SMART mode. The
vehicle drives, as the driver manu-
ally moves the shift lever.
The cruise control is activated : The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of the smart cruise control
system. (SMART mode is not deac-
tivated just by activating the cruise
control system.)
The transmission oil temperature is either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situa-
tions. However, an extremely high/
low transmission oil temperature
may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.

Hazardous Driving Conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud or sand:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in braking
or steering.
If stuck in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip
material under the drive wheels to
provide traction when stuck in ice,
snow, or mud.
Rocking the Vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and a for-
ward gear.
Try to avoid spinning the wheels, and
do not race the engine.
To prevent transmission wear, wait
until the wheels stop spinning before
shifting gears. Release the accelera-
tor pedal while shifting, and press
lightly on the accelerator pedal while
the transmission is in gear. Slowly
spinning the wheels in forward and
reverse directions causes a rocking
motion that may free the vehicle.If the tires spin at high speed the
tires can explode, and you or oth-
ers may be injured. Do not attempt
this procedure if people or objects
are anywhere near the vehicle.
The vehicle can overheat causing
an engine compartment fire or
other damage. Spin the wheels as
little as possible and avoid spin-
ning the wheels at speeds over 35
mph (56 km/h) as indicated on the
speedometer.

Downshifting with an automatic
transmission while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
WARNING

5-110
Driving your vehicle
If you are still stuck after rocking
the vehicle a few times, have the
vehicle pulled out by a tow vehicle
to avoid engine overheating, pos-
sible damage to the transmission,
and tire damage. See "Towing" in
chapter 6.
To prevent damage to the trans-
mission, turn OFF the ESC prior to
rocking the vehicle.
Smooth Cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration.
Driving at Night
Night driving presents more hazards
than driving in the daylight. Here are
some important tips to remember:
Slow down and keep more dis- tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
Adjust your mirrors to reduce the glare from other driver’s head-
lamps.
Keep your headlamps clean and properly aimed. Dirty or improperly
aimed headlamps will make it
much more difficult to see at night.
Avoid staring directly at the head- lamps of oncoming vehicles. You
could be temporarily blinded, and it
will take several seconds for your
eyes to readjust to the darkness.

■ Example

When towing your vehicle in an
emergency without wheel dollies :
1. Place the ignition switch in theACC position.
2. Place the shift lever in N (Neutral).
3. Release the parking brake.Emergency Towing
(if equipped)
If towing is necessary, we recom-
mend you to have it done by an
authorized HYUNDAI dealer or a
commercial tow truck service. If towing service is not available in an
emergency, your vehicle may be
temporarily towed using a cable or
chain secured to the emergency tow-
ing hook at the rear of the vehicle.
Use extreme caution when towing
the vehicle with a cable or chain. A
driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done
only on hard-surfaced roads for a
short distance and at low speeds.
Also, the wheels, axles, power train,
steering and brakes must all be in
good condition.
Failure to place the transmis-
sion shift lever in N (Neutral)
may cause internal damage to
the transmission.
CAUTION

Always follow these emergency tow-
ing precautions:
• Place the ignition switch in theACC position so the steering wheel
is not locked.
Place the shift lever in N (Neutral).
Release the parking brake.
Depress the brake pedal with more force than normal since you will
have reduced braking perform-
ance.
More steering effort will be required because the power steer-
ing system will be disabled.
Use a vehicle heavier than your own to tow your vehicle.
The drivers of both vehicles should communicate with each other fre-
quently.
Before emergency towing, check that the hook is not broken or dam-
aged.
Fasten the towing cable or chain securely to the hook.
Do not jerk the hook. Apply steady and even force. Use a towing cable or chain less
than 16 feet (5 m) long. Attach a
white or red cloth (about 12 inches
(30 cm) wide) in the middle of the
cable or chain for easy visibility.
Drive carefully so the towing cable or chain remains tight during tow-
ing.
Before towing, check the automat- ic transmission for fluid leaks under
your vehicle. If the automatic trans-
mission fluid is leaking, flatbed
equipment or a towing dolly must
be used.
ODH063025
To avoid damage to your vehicle
and vehicle components when
towing:
•Always pull straight ahead
when using the towing hooks.
Do not pull from the side or at
a vertical angle.
Do not use the towing hooks
to pull a vehicle out of mud,
sand or other conditions from
which the vehicle cannot be
driven out under its own
power.
Limit the vehicle speed to 10
mph (15 km/h) and drive less
than 1 mile (1.5 km) when tow-
ing to avoid serious damage
to the automatic transmis-
sion.

The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labor, parts and lubricants used.
Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an author-
ized HYUNDAI dealer. ALWAYS
follow these precautions for
performing maintenance work:
Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transmission vehicle) posi-
tion, apply the parking brake,
place the ignition switch in
the LOCK/OFF position.
Block the tires (front and back)
to prevent the vehicle from
moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
(Continued)
WARNING (Continued)
If you must run the engine
during maintenance, do so
out doors or in an area with
plenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.
