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 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 igni-
tion switch is in the ON position.
During that time, the ABS will gothrough self-diagnosis and the light
will go off if everything is normal. If
the light stays on, you may have a
problem with your ABS. We recom-
mend that you contact an authorized
HYUNDAI dealer as soon as possi-
ble.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 vehicle off.
Restart the vehicle. If the ABS
warning light is off, then your ABSsystem 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.
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.
WARNING

5-36
Driving your vehicle
Hill-Start Assist Control (HAC) (if equipped)
A vehicle has the tendency to slide
backwards on a steep slope, before
depressing the accelerator after a
stop. The HAC prevents the vehicle
from sliding backwards by automati-
cally operating the brake systems for
about 2 seconds. The brake systemsare automatically released, when the
accelerator pedal is depressed.Information
 The HAC does not operate when the shift lever is in P (Park) or N (Neutral).
 The HAC activates even when the ESC (Electronic Stability Control) is
off. However, it does not activate,
when the ESC does not normally
operate.
Emergency Stop Signal (ESS) (if equipped)
The Emergency Stop Signal system
alerts the driver behind by blinking
the stop lights, while sharply and
severely braking.
The system is activated when:
The vehicle suddenly stops. (Thedeceleration power exceeds 7 m/s 2
,
and the driving speed exceeds 55 km/h (34 mph).)
The ABS is activated.
The hazard warning flasher automat-
ically turns ON after blinking the stop
lights, when the driving speeds is
decelerated under 40 km/h (25 mph),
when the ABS is deactivated, and
when the sudden braking situation is
over. The hazard warning flasher turns
OFF, when the driving speed exceeds10 km/h (6 mph) after a complete
stop. The hazard warning flasher
turns OFF, when the vehicle drives at
a low speed for a certain period of
time. The driver can manually turn
OFF the hazard warning flasher by
pressing the button.
Information
The Emergency Stop Signal (ESS) sys-
tem will not work if the hazard warn-
ing flasher already blinks.
i
i
The HAC is activated only for
about 2 seconds, so alwaysdepress the accelerator pedal
to begin driving upwards after astop.

Prerequisite for activation
The AEB gets ready to be activated, when the AEB is selected on the
LCD display, and when the followingprerequisites are satisfied.
- The ESC (Electronic StabilityControl) is activated.
- To enable the system to detect pedestrians ahead, the vehicle
driving speed must be between 8km/h – 70 km/h (5 mph – 45 mph).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 8 km/h –180 km/h (5 mph – 110 mph).
When traveling above 80 km/h (50mph), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels,
such as abrupt stopping of the vehi-
cle in front, insufficient braking dis-
tance, or pedestrian detection. Also,
it controls the brakes in accordance
with the collision risk levels.

Completely stop the vehicle
on a safe location before
operating the switch on the
steering wheel to activate
/deactivate the AEB system.
The AEB automatically acti-
vates upon placing the Engine
Start/Stop button to the ON
position. The driver can deac-
tivate the AEB by cancelingthe system setting on the LCD
display.
The AEB automatically deacti-
vates upon canceling the ESC

What to do in an emergency
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (Park) and set the parking brake 3. Make sure that there is no hot
steam gushing out of the engine
compartment. When it is safe to
do so, open the engine compart-
ment, and check the water-pump
connector. When the water-pumpconnector is disconnected, stop
the engine, re-connect the water-
pump connector, and then re-start
the engine.
4. Set the temperature and the air flow to the maximum, and turn ON
the air conditioner. 5. When the Service warning light
( ) illuminates on the instru-
ment cluster, immediately stop the
engine, and contact an authorized
HYUNDAI dealer. When the
engine warning light ( ) illumi-
nates, or when the coolant or hotsteams gush out of the engine
compartment, leave the engine
compartment opened, while run-
ning the engine. This is to ventilate
the engine compartment and to
cool down the engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature
is sufficiently cooled down. Check
the coolant level. When it is insuffi-
cient, check its connection with the
radiator, the heater hose, and the
water pump for any leakage. When
there is no leakage, add the
coolant. However, if the problems
persists, such as the illumination of
the warning lights, leakages, or the
cooling-fan malfunction, which may
overheat the engine, immediately
stop the engine, and have your
vehicle checked by an authorized
HYUNDAI dealer.

Tire pressure monitoring sys- tem
Each tire, including the spare (if pro-
vided), should be checked monthlywhen cold and inflated to the inflation
pressure recommended by the vehi-
cle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If
your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation pres-
sure label, you should determine the
proper tire inflation pressure for
those tires.)As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale when one or more of yourtires is significantly under-inflated.
Accordingly, when the low tire pres-
sure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure. Driving on a signifi-cantly under-inflated tire causes the
tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire mainte-
nance, and it is the driver’s responsi-bility to maintain correct tire pres-
sure, even if under-inflation has not
reached the level to trigger illumina-
tion of the TPMS low tire pressure
telltale.Your vehicle has also been equipped
with a TPMS malfunction indicator toindicate when the system is not
operating properly. The TPMS mal-function indicator is combined with
the low tire pressure telltale. Whenthe system detects a malfunction,
the telltale will flash for approximate-
ly one minute and then remain con-
tinuously illuminated. This sequence
will continue upon subsequent vehi-
cle start-ups as long as the malfunc-
tion exists. When the malfunction indicator is illu-
minated, the system may not be able
to detect or signal low tire pressure
as intended. TPMS malfunctions may
occur for a variety of reasons, includ-ing the installation of replacement or
alternate tires or wheels on the vehi-
cle that prevent the TPMS from func-
tioning properly.
Always check the TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle toensure that the replacement or alter-
nate tires and wheels allow the TPMS
to continue to function properly.

Over-inflation or under-inflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure that
may cause loss of vehicle con-
trol resulting in an accident.
