ABS is an electronic braking system
that helps prevent a braking skid.
ABS allows the driver to steer and
brake at the same time.
Using ABS
To obtain the maximum benefit from
your ABS in an emergency situation,
do not attempt to modulate your
brake pressure and do not try to
pump your brakes. Depress your
brake pedal as hard as possible.
When you apply your brakes under
conditions which may lock the
wheels, you may hear sounds from
the brakes, or feel a corresponding
sensation in the brake pedal. This is
normal and it means your ABS is
active.
ABS does not reduce the time or dis-
tance it takes to stop the vehicle.
Always maintain a safe distance from
the vehicle in front of you.
ABS will not prevent a skid that
results from sudden changes in
direction, such as trying to take a
corner too fast or making a sudden
lane change. Always drive at a safe
speed for the road and weather con-
ditions.
ABS cannot prevent a loss of stabili-
ty. Always steer moderately when
braking hard. Severe or sharp steer-
ing wheel movement can still cause
your vehicle to veer into oncoming
traffic or off the road.
On loose or uneven road surfaces,
operation of the anti-lock brake sys-
tem may result in a longer stopping
distance than for vehicles equipped
with a conventional brake system.
The ABS warning light ( ) will stay
on for several seconds after the
Engine Start/Stop button is in the ON
position. During that time, the ABS
will go through self-diagnosis and the
light will go off if everything is nor-
mal. If the light stays on, you may
have a problem with your ABS. We
recommend that you contact an
authorized HYUNDAI dealer as soon
as possible.
(Continued)
•On roads where the road sur-
face is pitted or has different
surface height.
•Tire chains are installed on
your vehicle.
The safety features of an ABS
or ESC equipped vehicle should
not be tested by high speed
driving or cornering. This could
endanger the safety of yourself
or others.

5-44
Driving your vehicle
When you drive on a road having
poor traction, such as an icy road,
and apply your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light ( ) may illuminate. Pull
your car over to a safe place and
turn the engine off.
Restart the engine. If the ABS
warning light is off, then your ABS
system is normal.
Otherwise, you may have a prob-
lem with your ABS system. We
recommend that you contact an
authorized HYUNDAI dealer as
soon as possible.
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.
i
NOTICE
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, we recommend
that you contact your HYUNDAI
dealer as soon as possible.

To p r e v e n t d a m a g e t o t h e
transaxle:
•Do not allow wheel(s) of one
axle to spin excessively while
the ESC, ABS, and brake warn-
ing lights are displayed. The
repairs would not be covered by
the vehicle warranty. Reduce
engine power and do not spin
the wheel(s) excessively while
these lights are displayed.
•When operating the vehicle on a
dynamometer, ensure the ESC is
turned off (ESC OFF light illumi-
nated).
Information
Turning the ESC off does not affect
ABS or standard brake system opera-
tion.
Vehicle Stability Manag ement
(if equipped)
Ve h i c l e S t a b i l i t y M a n a g e m e n t ( V S M )
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.
VSM operation
VSM ON condition
The VSM operates when:
•The Electronic Stability Control
(ESC) is on.
•Vehicle speed is approximately
above 15 km/h (9mph) on curve
roads.
•Vehicle speed is approximately
above 20 km/h (12mph) when the
vehicle is braking on rough roads.
When operating
When you apply your brakes under
conditions which may activate the
ESC, you may hear sounds from the
brakes, or feel a corresponding sen-
sation in the brake pedal. This is nor-
mal and it means your VSM is active.
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
• The HAC does not operate when the
shift lever is in P (Park) or N
(Neutral)
• The HAC activates even though the
ESC (Electronic Stability Control) is
off but does not activate when the
ESC has malfunctioned.
Emergency Stop Signal (ESS)
(if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop light when the vehicle is
braked rapidly and severely.
The system is activated when:
•The vehicle suddenly stops (vehi-
cle speed is over 55km/h and the
vehicle deceleration is greater than
7 m/s2)
•The ABS is activating
When vehicle speed is under 40
km/h and the ABS deactivates or the
sudden stop situation is over, the
stop light will stop blinking. Instead,
the hazard warning flasher will turn
on automatically.
The hazard warning flasher will turn
off when vehicle speed is over
10km/h after the vehicle has
stopped. Also, it will turn off when the
vehicle is driven at low speed for
some time. You can turn it off manu-
ally by pushing the hazard warning
flasher switch.
Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher is already on.

Trailer brakes
If your trailer is equipped with a brak-
ing system, make sure it conforms
your country’s regulations and that it
is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes loaded, then it needs its
own brakes and they must be ade-
quate. Be sure to read and follow the
instructions for the trailer brakes so
you’ll be able to install, adjust and
maintain them properly. Be sure not
to tap into your vehicle's brake sys-
tem.
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 your-
self 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
longer and not nearly as responsive
as your vehicle is by itself.
Before you start, check the trailer
hitch and platform, safety chains,
electrical connector(s), lights, tires
and brakes.
During your trip, occasionally check
to be sure that the load is secure,
and that the lights and trailer brakes
are still working.
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
Yo u w i l l n e e d m o r e p a s s i n g d i s t a n c e
up ahead when you’re towing a trail-
er. And, because of the increased
vehicle length, you’ll need to go
much farther beyond the passed
vehicle before you can return to your
lane.
Do not use a trailer with its own
brakes unless you are absolute-
ly certain that you have proper-
ly set up the brake system. This
is not a task for amateurs. Use
an experienced, competent
trailer shop for this work.
WARNING

Driving your vehicle
Driving on hills
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
overheated and may not operate effi-
ciently.
On a long uphill grade, shift down
and reduce your speed to around 70
km/h (45 mph) to reduce the possi-
bility of engine and transaxle over-
heating.
If your trailer weighs more than the
maximum trailer weight without trail-
er brakes and you have an automat-
ic transaxle , you should drive in D
(Drive) when towing a trailer.
Operating your vehicle in D (Drive)
when towing a trailer will minimize
heat build-up and extend the life of
your transaxle.
To p r e v e n t e n g i n e a n d / o r
transaxle overheating:
•When towing a trailer on steep
grades (in excess of 6%) pay
close attention to the engine
coolant temperature gauge to
ensure the engine does not
overheat. If the needle of the
coolant temperature gauge
moves towards “H” (HOT), pull
over and stop as soon as it is
safe to do so, and allow the
engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.
•You must decide your vehicle
speed according to trailer
weight and uphill grade.
Parking on hills
Generally, if you have a trailer
attached to your vehicle, you should
not park your vehicle on a hill.
However, if you ever have to park
your trailer on a hill, here's how to do
it:
1. Pull the vehicle into the parking
space.
Turn the steering wheel in the
direction of the curb (right if head-
ed down hill, left if headed up hill).
2. Shift the vehicle to P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle).
3. Set the parking brake and shut off
the vehicle.
4. Place wheel chocks under the
trailer wheels on the down hill side
of the wheels.
5. Start the vehicle, hold the brakes,
shift to neutral, release the park-
ing brake and slowly release the
brakes until the trailer chocks
absorb the load.

Maintenance
Compact spare tire replacement
(if equipped)
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 mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
(Continued)
•The use of any other tire size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tire clearance, snow tire
clearance, and speedometer
reliability.
•It is best to replace all four
tires at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tires as a pair.
Replacing just one tire can
seriously affect your vehicle’s
handling.
•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 same size
originally supplied with the
vehicle. Using tires of a differ-
ent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.
•Driving on worn-out tires is
very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
•Yo u r v e h i c l e i s e q u i p p e d w i t h
tires designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tire and wheel that is
different from the one that is
originally installed on your
vehicle. It can affect the safety
and performance of your vehi-
cle, which could lead to han-
dling failure or rollover and
serious injury. When replacing
the tires, be sure to equip all
four tires with the tire and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
