ESC OFF usage
When driving
ESC should remain on for daily drivingwhenever possible.
To turn ESC off while driving, press the ESC OFF button while driving on a flat
road surface.
✽ ✽ NOTICE
• When operating the vehicle on a
dynamometer, ensure that the ESC is
turned off (ESC OFF light illuminat-
ed).
• Turning the ESC off does not affect ABS or brake system operation.
Good braking practices
After parking the vehicle, check to be
sure the parking brake is not engaged
and that the parking brake indicator
light is out before driving away.
Driving through water may get the brakes wet. They can also get wet when
the car is washed. Wet brakes can be
dangerous! Your car will not stop as
quickly if the brakes are wet. Wet brakes
may cause the car to pull to one side. To dry the brakes, apply the brakes light-
ly until the braking action returns to nor-
mal, taking care to keep the car under
control at all times. If the braking action
does not return to normal, stop as soon
as it is safe to do so and call an author-
ized HYUNDAI dealer for assistance.
Do not coast down hills with the car out of gear. This is extremely hazardous.
Keep the car in gear at all times, use
the brakes to slow down, then shift to a
lower gear so that engine braking will
help you maintain a safe speed.
Do not "ride" the brake pedal. Resting your foot on the brake pedal while driv-
ing can be dangerous because it can
result in the brakes overheating and los-
ing their effectiveness. It also increases
the wear of the brake components.
If a tire goes flat while you are driving, apply the brakes gently and keep the
car pointed straight ahead while you
slow down. When you are moving slow-
ly enough for it to be safe to do so, pull
off the road and stop in a safe place.
If your vehicle is equipped with an auto- matic transaxle, do not let your vehicle
creep forward. To avoid creeping for-
ward, keep your foot firmly on the brake
pedal when the vehicle is stopped.
WARNING
Never press the ESC OFF button
while ESC is operating (ESC indica-
tor light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip out
of control and cause an accident.
WARNING
Whenever you leave or park yourvehicle, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the P (Park) position. If the
parking brake is not fully
engaged, the vehicle may move
inadvertently and injure yourself
and others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

5-24
Use caution when parking on a hill.Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.
Under some conditions your parking brake can freeze in the engaged posi-
tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the
brakes are wet. If there is a risk that the
parking brake may freeze, apply it only
temporarily while you put the gear
selector lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle) and block the rear
wheels so the vehicle cannot roll. Then
release the parking brake.
Do not hold the vehicle on the incline with the accelerator pedal pressed.
This can cause the transaxle to over-
heat. Always use the brake pedal or
parking brake.Vehicle stability management
(VSM) (if equipped)
This system provides further enhance-
ments to vehicle stability and steering
responses when the vehicle is driving on a
slippery road or the vehicle detects a
change in coefficient of friction between
the left and right wheels.
VSM operation
When the VSM is in operation, ESC indi-
cator light ( ) blinks.
When the vehicle stability management
is operating properly, you can feel a slight
pulsation in the vehicle and/or abnormal
steering responses (EPS). This is only
the effect of brake and EPS control and
is a normal operating condition.
The VSM does not operate when:
Driving on a gradient or incline
Driving in reverse
ESC OFF indicator light ( ) remainson the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to turn off
the ESC, the VSM will also cancel and the
ESC OFF indicator light ( ) illuminates.
To turn on the VSM, press the button again.
The ESC OFF indicator light goes out.
Malfunction indicator
The VSM can be deactivated even if you
don't cancel the VSM operation by press-
ing the ESC OFF button. It indicates that
a malfunction has been detected some-
where in the Electric Power Steering sys-
tem or VSM system. If the ESC indicator
light ( ) or EPS warning light ( )
remains on, take your vehicle to an
authorized HYUNDAI dealer and have
the system checked.

Hill-start assist control (HAC)
(if equipped)
Hill start Assist Control is a convenience
function. The main intent is to help pre-
vent the vehicle from rolling backwards
while taking off uphill from a stop. HAC
holds the braking pressure built up by the
driver during stopping for 2 seconds after
releasing the brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as soon
as the system detects the driver's inten-
tion to drive off.
✽ ✽NOTICE
• The HAC does not operate when the
transaxle shift lever is in the P (Park)
or N (Neutral) position.
• The HAC activates even though the ESC is off but it does not activate
when the ESC has malfunctioned. WARNING
The Vehicle Stability Management
system is not a substitute for
safe driving practices but a sup-
plementary function only. It is the
responsibility of the driver to
always check the speed and the
distance to the vehicle ahead.
Always hold the steering wheel
firmly while driving.
Your vehicle is designed to acti- vate according to the driver's
intention, even with installed
VSM. Always follow all the normal
precautions for driving at safe
speeds for the conditions –
including driving inclement
weather and on a slippery road.
Driving with varying tire or wheel sizes may cause the VSM system
to malfunction. When replacing
tires, make sure they are the
same size as your original tires.
WARNING
The HAC is usually activated only
for 2 seconds: If the built-up brake
hold pressure is insufficient to hold
the vehicle, the driver must quickly
activate the brake pedal to prevent
the vehicle from rolling backward.
Unexpectedly rolling backward
could cause an accident, and seri-
ous injury.

➀CRUISE indicator
➁SET indicator
The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without resting your foot on
the accelerator pedal.
This system is designed to function
above approximately 25 mph (40 km/h).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
If the cruise control is left on, (CRUISE indicator light in the
instrument cluster illuminated)
the cruise control can be activat-
ed unintentionally. Keep the
cruise control system off
(CRUISE indicator light OFF)
when the cruise control is not in
use, to avoid inadvertently set-
ting a speed.
Use the cruise control system only when traveling on open
highways in good weather.
Do not use the cruise control when it may not be safe to keep
the car at a constant speed, for
instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6% up-hill
or down-hill roads.
Pay particular attention to the driving conditions whenever
using the cruise control system.
Be careful when driving downhill using the cruise control system,
which may increase the vehicle
speed.
(Continued)
(Continued)
Do not use the Cruise Controlwhen it may be unsafe to keep
the vehicle at a constant speed:
- When driving in heavy traffic orwhen traffic conditions make it
difficult to drive at a constant
speed
- When driving on rainy, icy, or snow-covered roads
- When driving on hilly or windy roads
- When driving in windy areas
- When driving with limited view (possibly due to bad weather
such as fog, snow, rain and
sandstorm)

✽
✽NOTICE
• During normal cruise control opera-
tion, when the SET switch is activated
or reactivated after applying the
brakes, the cruise control will ener-
gize after approximately 3 seconds.
This delay is normal.
• To activate cruise control, depress the brake pedal at least once after turning
the ignition switch to the ON position
or starting the engine. This is to check
if the brake switch which is important
part to cancel cruise control is in nor-
mal condition.
To set cruise control speed:
1. Push the cruise ON-OFF button on the
steering wheel to turn the system on.
The CRUISE indicator light in the
instrument cluster will illuminate.
2. Accelerate to the desired speed, which must be more than 25 mph (40 km/h). 3. Move the toggle switch down (to SET-),
and release it at the desired speed.
The SET indicator light in the instru-
ment cluster will illuminate. Release
the accelerator at the same time. The
desired speed will automatically be
maintained.
On a steep grade, the vehicle may slowdown or speed up slightly while goinguphill or downhill.

Driving your vehicle
To cancel cruise control, do one
of the following:
Press the brake pedal.
Press the clutch pedal with a manualtransaxle.
Shift the shift lever into N (Neutral) with an automatic transaxle
Press the CANCEL switch located on the steering wheel.
Decrease the vehicle speed lower than the memory speed by 9 mph (15 km/h).
Decrease the vehicle speed to less than approximately 25 mph (40 km/h).
Each of these actions will cancel cruise
control operation (the SET indicator lightin the instrument cluster will go off), but it will not turn the system off. If you wish toresume cruise control operation, movethe toggle switch up (to RES+). You willreturn to your previously preset speed.
To resume cruising speed at
more than approximately 25 mph
(40 km/h):
If any method other than the ON-OFF
switch was used to cancel cruising speed
and the system is still activated, the most
recent set speed will automatically
resume when you move the toggle switch
up (to RES+).
✽ ✽ NOTICE
Always check the road conditions when
you move the toggle switch up (to RES+)
to resume the speed.
To turn cruise control off, do one
of the following:
Push the cruise ON/OFF button (the
CRUISE indicator light in the instru-
ment cluster will go off).
Turn the ignition off.
Both of these actions cancel cruise con- trol operation. If you want to resume cruise control operation, repeat the stepsprovided in "To set cruise control speed" on the previous page.

Active ECO operation
Active ECO helps improve fuel efficiency
by controlling the engine and transaxle.
But fuel-efficiency can be changed by the
driver's driving habits and road condi-
tions.
When the Active ECO button ispressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
If Active ECO is turned off, it will return to the normal mode.
Limitation of Active ECO
operation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
When the coolant temperature is low:
The system will be limited until engine
temperature becomes normal.
When driving up a hill: The system will be limited to gain
power when driving uphill because the
engine torque is required.
When using Sport Mode: The system will be limited according to
the manually selected gear.
When the accelerator pedal is deeply pressed for a few seconds:
The system will be limited, judging that
the driver desires additional accelera-
tion. Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-
ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever
possible. Always maintain a safe dis-
tance from other vehicles so you can
avoid unnecessary braking. This also
reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your car uses.
Driving at a moderate speed, especially
on the highway, is one of the most effec-
tive ways to reduce fuel consumption.
Don't "ride" the brake pedal. This can increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.

ECONOMICAL OPERATION

5-31
Driving your vehicle
Take care of your tires. Keep theminflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption.
Keep your car in good condition. For better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in section 7. If you drive your
car in severe conditions, more frequent
maintenance is required (see section 7
for details).
Keep your car clean. For maximum serv- ice, your vehicle should be kept clean
and free of corrosive materials. It is
especially important that mud, dirt, ice,
etc. not be allowed to accumulate on the
underside of the car. This extra weight
can result in increased fuel consumption
and also contribute to corrosion.
Travel lightly. Don't carry unnecessary weight in your car. Weight reduces fuel
economy. Don't let the engine idle longer than
necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
Remember, your vehicle does not require extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds.
Use your air conditioning sparingly. The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions. Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

5-33
Driving your vehicle
✽
✽NOTICE
The ESC system should be turned OFF
prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tire wear will be held
to a minimum.
Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
WARNING- Spinning tires
Do not spin the wheels, especially
at speeds more than 35 mph (56
km/h). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat
which could result in tire damage
that may injure bystanders.
OBH058035LOMC035004
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people or
objects.
