Driving your vehicle
The ABS continuously senses the speed
of the wheels. If the wheels are going to
lock, the ABS system repeatedly modu-
lates the hydraulic brake pressure to the
wheels.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ABS is active.
In order to obtain the maximum benefit
from your ABS in an emergency situa-
tion, do not attempt to modulate your
brake pressure and do not try to pump
your brakes. Press your brake pedal as
hard as possible or as hard as the situa-
tion warrants and allow the ABS to con-
trol the force being delivered to the
brakes.
✽ ✽NOTICEA click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the anti-lock brake system
is functioning properly. Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
 Always slow down when cornering. The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
 On loose or uneven road surfaces, operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.

CAUTION
 If the ABS warning light is on and
stays on, you may have a problemwith the ABS. In this case, howev-er, your regular brakes will worknormally.
 The ABS warning light will stay on for approximately 3 seconds afterthe ignition switch is ON. Duringthat time, the ABS will go throughself-diagnosis and the light will gooff if everything is normal. If thelight stays on, you may have aproblem with your ABS. Contactan authorized HYUNDAI dealer assoon as possible.
(Continued)
 On roads where the road surface is pitted or has different surface
height.
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.

Driving your vehicle
The Electronic Stability Control (ESC)
system is an electronic system designed
to help the driver maintain vehicle control
under adverse conditions. It is not a
substitute for safe driving practices.
Factors including speed, road conditions
and driver steering input can all affect
whether ESC will be effective in
preventing a loss of control. It is still your
responsibility to drive and corner at
reasonable speeds and to leave a
sufficient margin of safety.
When you apply your brakes under con-
ditions which may lock the wheels, you
may hear a “tik-tik’’ sound from the
brakes, or feel a corresponding sensation
in the brake pedal. This is normal and it
means your ESC is active.✽ ✽NOTICEA click sound may be heard in the
engine compartment when the vehicle
begins to move after the engine is start-
ed. These conditions are normal and
indicate that the Electronic Stability
Control System is functioning properly.
ESC operationESC ON condition
 When the ignition is turnedON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.
 Press the ESC OFF button for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
 When starting the engine, you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem. When operating
When the ESC is in operation,
ESC indicator light blinks.
 When the Electronic StabilityControl is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and indi-
cates nothing unusual.
 When moving out of the mud or driving on a slippery road,
pressing the accelerator
pedal may not cause the
engine rpm (revolutions per
minute) to increase.
ESC operation offESC OFF state
 To cancel ESC operation,press the ESC OFF button
(ESC OFF indicator light illu-
minates).
 If the ignition switch is turned to LOCK position when ESC
is off, ESC remains off. Upon
restarting the engine, the
ESC will automatically turn
on again.

5Indicator lightWhen ignition switch is turned to ON, the
indicator light illuminates, then goes off if
the ESC system is operating normally.
The ESC indicator light blinks whenever
ESC is operating or illuminates when
ESC fails to operate.
The ESC OFF indicator light comes on
when the ESC is turned off with the but-
ton.
ESC OFF usageWhen driving
 ESC should be turned on for daily driv-
ing whenever possible.
 To turn ESC off while driving, press the ESC OFF button while driving on a flat
road surface.
Never press the ESC OFF button while
ESC is operating (ESC indicator light
blinks).
If ESC is turned off while ESC is operat-
ing, the vehicle may slip out of control.✽ ✽ 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.
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size as your original tires.
WARNING
The Electronic Stability Control sys-
tem is only a driving aid; use pre-
cautions for safe driving by slowing
down on curved, snowy, or icy
roads. Drive slowly and don’t
attempt to accelerate whenever the
ESC indicator light is blinking, or
when the road surface is slippery.

5Each of these actions will cancel cruise
control operation (the SET indicator lightin the instrument cluster will go off), but itwill not turn the system off. If you wish to resume cruise control operation, pushthe RES+ switch located on your steeringwheel. You will return to your previously preset speed.
To resume cruising speed at
more than approximately 25 mph
(40 km/h):If any method other than the cruise
ON/OFF switch was used to cancel cruis-
ing speed and the system is still activat-
ed, the most recent set speed will auto-
matically resume when the RES+ switch
is pushed.
It will not resume, however, if the vehicle
speed has dropped below approximately
25 mph (40 km/h).✽ ✽ NOTICEAlways check the road conditions when
pressing the RES+ switch 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.

Driving your vehicle
 Remember, your vehicle does notrequire 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.

Use high quality ethylene glycol
coolantYour vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.Check battery and cablesWinter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in section
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Change to "winter weight" oil if
necessaryIn some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.Check spark plugs and ignition
systemInspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
 The use of chains may adversely
affect vehicle handling.
 Do not exceed 20 mph (30 km/h) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
 Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
 Avoid sharp turns or locked- wheel braking.
CAUTION
 Chains that are the wrong size or improperly installed can damageyour vehicle's brake lines, sus-pension, body and wheels.
 Stop driving and retighten the chains any time you hear themhitting the vehicle.
