Driving your vehicle
ESC operation
ESC ON condition
When the ignition switch is in the ON
position, the ESC and the ESC OFF
indicator lights illuminate for approxi-
mately three seconds and goes off,
then the ESC is turned on.
If this light stays on, your vehicle may
have a malfunction with the ESC
system. Have your vehicle checked
by an authorized HYUNDAI dealer
as soon as possible.When operating
When the ESC is in opera-
tion, the ESC indicator light
blinks:
brakes under conditions
which may lock the
wheels, you may hear
sounds from the brakes, or
feel a corresponding sen-
sation in the brake pedal.
This is normal and it
means your ESC is active.
the engine may not
respond to the accelerator
as it does under routine
conditions.
in use when the ESC acti-
vates, the cruise control
automatically disengages.
The Cruise Control can be
reengaged when the road
conditions allow. See
"Cruise Control System"
later in this chapter.WARNING
Never drive too fast for the road
conditions or too quickly when
cornering. The ESC system will
not prevent accidents.
Excessive speed in turns,
abrupt maneuvers, and
hydroplaning on wet surfaces
can result in severe accidents.

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 acti-
vate when the ESC has malfunc-
tioned.
Good braking practices
After being parked, 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 vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one side.
To dry the brakes, apply the brakes
lightly until the braking action returns
to normal, taking care to keep the
vehicle 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 authorized
HYUNDAI dealer for assistance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle 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.
Don't "ride" the brake pedal. Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
WARNING
Whenever you leave or parkyour vehicle, always set the
parking brake as far as possi-
ble and fully engage the vehi-
cle'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 inadvertent movement
of the vehicle which can injure
occupants or pedestrians.

Driving your vehicle
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 gallon (liter) of fuel. To oper-
ate your vehicle as economically as
possible, use the following driving
suggestions to help save money in
both fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever possi-
ble. 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
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
Section 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
Section 7 for details).
Keep your vehicle clean. For maxi- mum service, 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 vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. 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.
ECONOMICAL OPERATION

Driving your vehicle
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. 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 the parking brake may
freeze, apply it only temporarily while
you put the shift lever in P (automat-
ic transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tire chains, tow straps or
chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a win-
dow scraper, gloves, ground cloth,
coveralls or a blanket, etc.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign objects or
materials which prevent cooling of
the engine, in the engine compart-
ment, may cause a failure or com-
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

Driving with a trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself
with the feel of handling and braking
with the added weight of the trailer.
And always keep in mind that the
vehicle you are driving is now a good
deal longer and not nearly so respon-
sive as your vehicle is by itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and mirror adjustment. If the trailer
has electric brakes, start your vehicle
and trailer moving and then apply the
trailer brake controller by hand to be
sure the brakes are working. This lets
you check your electrical connection
at the same time.
During your trip, check occasionally
to be sure that the load is secure,
and that the lights and any trailer
brakes are still working.
Following distance
Stay at least twice as far behind the
vehicle ahead as you would when
driving your vehicle without a trailer.
This can help you avoid situations
that require heavy braking and sud-
den turns.
Passing
You'll need more passing distance up
ahead when you're towing a trailer.
And, because of the increased vehi-
cle length, you'll need to go much far-
ther beyond the passed vehicle
before you can return to your lane.
Due to the added load to the engine
when going uphill the vehicle may
also take longer to pass than it would
on flat ground.
Backing up
Hold the bottom of the steering
wheel with one hand. Then, to move
the trailer to the left, just move your
hand to the left. To move the trailer to
the right, move your hand to the
right. Always back up slowly and, if
possible, have someone guide you.
Making turns
When you're turning with a trailer,
make wider turns than normal. Do
this so your trailer won't strike soft
shoulders, curbs, road signs, trees,
or other objects near the edge of the
road. Avoid jerky or sudden maneu-
vers. Signal well in advance before
turning or lane changes.

Driving your vehicle
Turn signals when towing a trailer
When you tow a trailer, your vehicle
has to have a different turn signal
flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever you signal a turn or
lane change. Properly connected,
the trailer lights will also flash to alert
other drivers you're about to turn,
change lanes, or stop.
When towing a trailer, the green
arrows on your instrument panel will
flash for turns even if the bulbs on the
trailer are burned out. Thus, you may
think drivers behind you are seeing
your signals when, in fact, they are
not. It's important to check occasion-
ally to be sure the trailer bulbs are still
working. You must also check the
lights every time you disconnect and
then reconnect the wires.
Do not connect a trailer lighting sys-
tem directly to your vehicle's lighting
system. Use only an approved trailer
wiring harness.
An authorized HYUNDAI dealer can
assist you in installing the wiring har-
ness.
Driving on grades
Reduce speed and shift to a lower
gear before you start down a long or
steep downgrade. If you don’t shift
down, you might have to use your
brakes so much that they would get
hot and no longer operate efficiently.
On a long uphill grade, shift down
and reduce your speed to around 45
mph (70 km/h) to reduce the possi-
bility of engine and transaxle over-
heating.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build up and extend the life of
your transaxle.WARNING
Failure to use an approved trail-
er wiring harness could result
in damage to the vehicle electri-
cal system and/or personal
injury.

What to do in an emergency
IN CASE OF AN EMERGENCY WHILE DRIVING
If the engine stalls at a cross-
road or crossing
If the engine stalls at a crossroad or
crossing, set the shift lever in the N
(Neutral) position and then push the
vehicle to a safe place.
If you have a flat tire while
driving
If a tire goes flat while you are driving:
1. Take your foot off the acceleratorpedal and let the car slow down
while driving straight ahead. Do
not apply the brakes immediately
or attempt to pull off the road as
this may cause a loss of control.
When the car has slowed to such
a speed that it is safe to do so,
brake carefully and pull off the
road. Drive off the road as far as
possible and park on firm, level
ground. If you are on a divided
highway, do not park in the median
area between the two traffic lanes.
2. When the vehicle is stopped, turn on your emergency hazard flashers,
set the parking brake and put the
transaxle in P.
3. Have all passengers get out of the car. Be sure they all get out on the
side of the car that is away from
traffic.
4. When repairing a flat tire, follow the instruction provided later in
this section.
If engine stalls while driving
1. Reduce your speed gradually,keeping a straight line. Move cau-
tiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your vehicle will not start, contact
an authorized HYUNDAI dealer or
seek other qualified assistance.
✽ ✽NOTICE
If there was a check engine light and
loss of power or stall, it is best if safe
to do so to wait at least 10 seconds to
restart a vehicle after it stalls. This
may reset the car so it will no longer
run at low power (limp home) condi-
tion.
