Anti-lock Brake System (ABS)
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. An Anti-lock Braking System
(ABS) or an Electronic Stability
Control (ESC) system will not
prevent accidents due to
improper or dangerous driving
manoeuvres. 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 vehicles
equipped with ABS or ESC may
be longer than for those without
these systems in particular
road conditions.
Drive your vehicle at reduced
speeds in the following condi-
tions:
•Rough, gravel or snow-cov-
ered roads.
(Continued)
WARNING
(Continued)
•On roads where the road sur-
face is pitted or uneven.
•Tyre 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.

5-36
Driving your vehicle
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 ABS may result in a
longer stopping distance than for
vehicles equipped with a convention-
al 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
authorised HYUNDAI dealer as soon
as possible.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 vehicle 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
authorised 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.
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.

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 whilst driving, press
the ESC OFF button whilst driving on
a flat road surface.To prevent damage to the
transaxle:
• Do not allow wheel(s) of one
axle to spin excessively whilst
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 whilst
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 Management
(if equipped)
Vehicle Stability Management (VSM)
helps ensure the vehicle stays stable
when accelerating or braking sud-
denly on wet, slippery and rough
roads where traction over the four
tyres 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.

Hill-Start Assist Control (HAC)
(if equipped)
The Hill-Start Assist Control (HAC)
prevents the vehicle from rolling rear-
wards when starting a vehicle from a
stop on a hill. The system operates
the brakes automatically for approxi-
mately 2 seconds and releases the
brake when the accelerator pedal is
depressed or after 2 seconds.
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 your vehicle
by blinking the stop light when the
vehicle is braked rapidly and severe-
ly.
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/s
2)
• 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 and 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.
i
Always be ready to depress the
accelerator pedal when starting
off on a incline. The HAC acti-
vates only for approximately 2
seconds.

Safety chains
You should always attach chains
between your vehicle and your trail-
er. Cross the safety chains under the
tongue of the trailer so that the
tongue will not drop to the road if it
becomes separated from the towbar.
Instructions about safety chains may
be provided by the towbar manufac-
turer or trailer manufacturer. Follow
the manufacturer's recommendation
for attaching safety chains. Always
leave just enough slack so you can
turn with your trailer. And, never
allow safety chains to drag on the
ground.
Trailer brakes
If your trailer is equipped with a brak-
ing system, make sure it conforms to
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
towbar and platform, safety chains,
electrical connector(s), lights, tyres
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.
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.

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 kerb.
2.Shift the vehicle to P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle).
3.Set the parking brake and turn off
the vehicle.
4.Place wheel chocks under the trail-
er wheels on the down hill side of
the wheels.
5.Start the vehicle, hold the brakes,
shift to neutral, release the parking
brake and slowly release the
brakes until the trailer chocks
absorb the load.
6.Reapply the brakes and parking
brakes.7.Move the shift lever to P (Park, for
automatic transaxle vehicle) or 1st
gear when the vehicle is parked on
a uphill grade and in R (Reverse)
on a downhill (for manual transaxle
vehicle).
8.Turn off the vehicle and release the
vehicle brakes but leave the park-
ing brake set.
To prevent serious or fatal
injury:
Do not get out of the vehicle
without the parking brake firmly
set. If you have left the engine
running, the vehicle can move
suddenly. You and others could
be seriously or fatally injured.

Maintenance
Compact spare tyre replace-
ment (if equipped)
A compact spare tyre has a shorter
tread life than a regular size tyre.
Replace it when you can see the
tread wear indicator bars on the tyre.
The replacement compact spare tyre
should be the same size and design
as the one provided with your new
vehicle and should be mounted on
the same compact spare tyre wheel.
The compact spare tyre is not
designed to be mounted on a regular
size wheel, and the compact spare
tyre wheel is not designed for mount-
ing a regular size tyre. (Continued)•The use of any other tyre size
or type may seriously affect
ride, handling, ground clear-
ance, stopping distance, body
to tyre clearance, snow tyre
clearance, and speedometer
reliability.
•It is best to replace all four
tyres at the same time. If that
is not possible, or necessary,
then replace the two front or
two rear tyres as a pair.
Replacing just one tyre can
seriously affect your vehicle’s
handling.
•The ABS works by comparing
the speed of the wheels. Tyre
size can affect wheel speed.
When replacing tyres, all four
tyres must use the same size
originally supplied with the
vehicle. Using tyres of a dif-
ferent size can cause the ABS
(Anti-lock Brake System) and
ESC (Electronic Stability
Control) (if equipped) to work
irregularly.
•Driving on worn-out tyres is
very hazardous and will
reduce braking effectiveness,
steering accuracy, and trac-
tion.
•Your vehicle is equipped with
tyres designed to provide for
safe ride and handling capa-
bility. Do not use a size and
type of tyre 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 tyres, be sure to equip all
four tyres with the tyre and
wheel of the same size, type,
tread, brand and load-carrying
capacity.
