but should go off after approximately 3
seconds. To switch to ESP OFF mode,
press the ESP OFF button . The ESP
OFF indicator will illuminate indicating
the ESP is deactivated.
If this indicator stays on when ESP OFF
is not selected, the ESP may have a mal-
function. Take your car to an authorized
HYUNDAI dealer and have the system
checked.
If you use the parking brake to stop the
vehicle with the ESP system in the stand-
by position when the brake is not work

illuminated for about 5 minutes.E070504ABH-EE
ESP OFF usage
When driving
ESP should be turned on for daily driv-
ing whenever possible. If ESP is turned
off, it is difficult to make a turn or driveup a hill.
To turn ESP off while driving, press the ESP OFF button while driving on a
flat road surface.
Never press the ESP OFF button
while ESP is operating (ESP indicator
light blinks).
If ESP is turned off while ESP is operat-
ing, it may be very dangerous because of
unexpected vehicle slip.
✽✽ NOTICE
 When operating the vehicle on a dynamometer, ensure that the ESP is
turned off (ESP OFF light illumi-
nated). If the ESP is left on, it may
prevent the vehicle speed from
increasing, and result in false diagno-
sis.
 Turning the ESP off does not affect ABS or brake system operation.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESP system to
malfunction. When replacing tires,make sure they are the same size asyour original tires.
WARNING
The Electronic Stability Program
system is only a driving aid; use
precautions for safe driving by
slowing down on curved, snowy, or
icy roads. Drive slowly and don’t
attempt to accelerate whenever the
ESP indicator light is blinking, or
when the road surface is slippery.
CAUTION
Do not use the parking brake to stop the vehicle except in an emer-gency situation.

CAUTION
Underinflation also results in
excessive wear, poor handlingand reduced fuel economy. Wheel deformation also ispossible. Keep your tire pres-sures at the proper levels. If a tire frequently needs refilling,have it checked by an author-ized HYUNDAI dealer.
Overinflation produces a harsh ride, excessive wear atthe center of the tire tread, anda greater possibility of dam-age from road hazards.
TIRES AND WHEELS
G200100AUN Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle. G200200AEN Recommended cold tire inflation pressures All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure,
refer to “Tire and wheels” in section8. All specifications (sizes and pres-
sures) can be found on a label
attached to the vehicle.
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation andother tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Compact spare tire replacement (ifequipped)
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mountedon the same compact spare tire
wheel. The compact spare tire is notdesigned to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire. G200700ABK Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim widthand offset.
✽✽
NOTICE
The front tire size is different from
the rear tire size. So when you rotate
tires, check the tire and wheel size.
(Continued)
Using tires and wheel other than the recommended sizes
could cause unusual handling
characteristics and poor vehi-
cle control, resulting in a seri-ous accident.
Wheels that do not meet HYUNDAI’s specifications
may fit poorly and result in
damage to the vehicle or
unusual handling and poor
vehicle control.
The ABS works by comparing the speed of the wheels. Tire
size can affect wheel speed.
When replacing tires, all 4
tires must use the size origi-
nally supplied with the vehi-
cle. Using tires of a different
size can cause the ABS (Anti-
lock Brake System) and ESP
(Electronic Stability Program)
to work irregularly.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,speedometer and odometer cal-
ibration, headlight aim and
bumper height.
