Driving your vehicle
Do not apply the accelerator pedal while the parking brake is
engaged. If you depress the
accelerator pedal with the park-
ing brake engaged, warning will
sound. Damage to the parking
brake may occur.
Driving with the parking brake on can overheat the braking sys-
tem and cause premature wear
or damage to brake parts. Make
sure the parking brake is
released and the Brake Warning
Light is off before driving. Check the Parking
Brake Warning Light
by placing the Engine
Start/Stop button to
the ON position (vehi-
cle not in the ready
( ) mode).
This light will be illuminated when the
parking brake is applied with the
Engine Start/Stop button in the
START or ON position.
Before driving, be sure the parking
brake is released and the Brake
Warning Light is OFF.
If the Parking Brake Warning Light
remains on after the parking brake is
released while the vehicle is in the
ready ( ) mode, there may be a
malfunction in the brake system.
Immediate attention is necessary.
If at all possible, cease driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location.
Anti-lock Brake System (ABS)NOTICE
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 vehi-
cle 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.

WARNING

5-28
Driving your vehicle
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.

Driving your vehicle

Press and hold the ESC OFF button
continuously for more than 3 sec-
onds. The ESC OFF indicator light
and message illuminates and a
warning chime sounds. In this state,
both the traction control function of
ESC (engine management) and the
brake control function of ESC (brak-
ing management) are disabled.
If the Engine Start/Stop button is
placed to the OFF position when
ESC is off, ESC remains off. Upon
restarting the vehicle, the ESC will
automatically turn on again.
Indicator lights
When the Engine Start/Stop button
is placed to the ON position, the ESC
indicator light illuminates, then goes
off if the ESC system is operating
normally.
The ESC indicator light blinks when-
ever the ESC is operating.
If ESC indicator light stays on, your
vehicle may have a malfunction with
the ESC system. When this warning
light illuminates have your vehicle
checked by an authorized HYUNDAI
dealer as soon as possible.
The ESC OFF indicator light comes
on when the ESC is turned off. Driving with wheels and tires with
different sizes may cause the ESC
system to malfunction. Before
replacing tires, make sure all four
tires and wheels are the same
size. Never drive the vehicle with
different sized wheels and tires
installed.NOTICE

ESC OFF usage
When Driving
The ESC OFF mode should only be
used briefly to help free the vehicle if
stuck in snow or mud by temporarily
stopping operation of the ESC to
maintain wheel torque.
To turn ESC off while driving, press
the ESC OFF button while driving on
a flat road surface.To prevent damage to the trans-
mission:
Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and parking brake
warning lights are displayed.
The repairs would not be cov-
ered by the vehicle warranty.
Reduce engine power and do
not spin the wheel(s) excessive-
ly while these lights are dis-
played.
When operating the vehicle on a dynamometer, make sure the
ESC is turned off (ESC OFF light
illuminated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Management
(VSM)
The Vehicle Stability Management
(VSM) is a function of the Electronic
Stability Control (ESC) system. It
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tires can suddenly become uneven.
i
NOTICE
Take the following precautions
when using the Vehicle Stability
Management (VSM):
ALWAYS check the speed and
the distance to the vehicle
ahead. The VSM is not a sub-
stitute for safe driving prac-
tices.
Never drive too fast for the
road conditions. The VSM sys-
tem will not prevent acci-
dents. Excessive speed in bad
weather, slippery and uneven
roads can result in severe
accidents.

Information
• During normal cruise control opera-tion, when the SET switch is activat-
ed or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• Before activating the cruise control function, the system will check to
verify that the brake switch is oper-
ating normally. Depress the brake
pedal at least once after turning ON
the ignition or starting the engine.
To set Cruise Control speed
1. Press the CRUISE button on the steering wheel to turn the system
on. The cruise ( ) indi-
cator will illuminate.
2. Accelerate to the desired speed, which must be more than 20 mph
(30 km/h). 3. Push the toggle switch down
(SET-), and release it. The SET
indicator light will illuminate.
4. Release the accelerator pedal.
Information
On a steep slope, the vehicle may
slightly slow down or speed up, while
driving uphill or downhill.

Driving your vehicle
Driving too fast through large pud- dles can affect your brakes. If you
must go through puddles, try to
drive through them slowly.
If you believe your brakes may be wet, apply them lightly while driv-
ing until normal braking operation
returns.
Hydroplaning
If the road is wet enough and you are
going fast enough, your vehicle may
have little or no contact with the road
surface and actually ride on the
water. The best advice is SLOW
DOWN when the road is wet.
The risk of hydroplaning increas-
es as the depth of tire tread
decreases, refer to "Tire Tread" in
chapter 7.
Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
reduced.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or
damage the tires.
Do not install worn-out or damaged
tires, which may reduce traction or
adversely affect vehicle handling.
This could lead to sudden tire failure
that may cause loss of vehicle con-
trol resulting in an accident.
Information
Never over-inflate your tires above the
maximum inflation pressure, as speci-
fied on your tires.
Fuel, engine coolant and engineoil
Driving at higher speeds on the high-
way consumes more fuel and is less
efficient than driving at a slower,
more moderate speed. Maintain a
moderate speed in order to conserve
fuel when driving on the highway.
Be sure to check both the engine
coolant level and the engine oil
before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
i
In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. Make sure all
passengers are wearing their
seat belts.

The severe weather conditions of
winter quickly wear out tires and
cause other problems. To minimize
winter driving problems, you should
take the following suggestions:
Snow or Icy Conditions
You need to keep sufficient distance
between your vehicle and the vehicle
in front of you.
Apply the brakes gently. Speeding,
rapid acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause the vehicle to skid.
To drive your vehicle in deep snow, it
may be necessary to use snow tires
or to install tire chains on your tires.
Always carry emergency equipment.
Some of the items you may want to
carry include tire chains, tow straps
or chains, a flashlight, emergency
flares, sand, a shovel, jumper cables,
a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
Snow tires
If you mount snow tires on your vehi-
cle, make sure to use radial tires of
the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s
handling in all weather conditions.
The traction provided by snow tires
on dry roads may not be as high as
your vehicle's original equipment
tires. Check with the tire dealer for
maximum speed recommendations.
Information
Do not install studded tires without
first checking local, state and munici-
pal regulations for possible restric-
tions against their use.
Tire chains
Since the sidewalls of radial tires are
thinner than other types of tires, they
may be damaged by mounting some
types of tire chains on them.
Therefore, the use of snow tires is
recommended instead of tire chains.
If tire chains must be used, use gen-
uine HYUNDAI parts and install the
tire chain after reviewing the instruc-
tions provided with the tire chains.
Damage to your vehicle caused by
improper tire chain use is not cov-
ered by your vehicle manufacturer’s
warranty.
i
Snow tires should be equivalent
in size and type to the vehicle's
standard tires. Otherwise, the
safety and handling of your
vehicle may be adversely affect-
ed.
