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.✽ ✽NOTICE
A 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. WARNING
Never drive too fast according to
the road conditions or too quickly
when cornering. Electronic stability
control (ESC) will not prevent acci-
dents. Excessive speed in turns,
abrupt maneuvers and hydroplan-
ing on wet surfaces can still result
in serious accidents. Only a safe
and attentive driver can prevent
accidents by avoiding maneuvers
that cause the vehicle to lose trac-
tion. Even with ESC installed,
always follow all the normal precau-
tions for driving - including driving
at safe speeds for the conditions.

Indicator light
When the ignition switch is turned ON,
the indicator light illuminates, then goes
off if ESC system is operating normally.
The ESC indicator light blinks whenever
ESC is operating.
ESC OFF indicator light comes on when
either the ESC is turned off with the but-
ton, or ESC fails to operate when turned
on.
ESC OFF usage
When driving
It’s a good idea to keep the ESC turnedon for daily driving 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). If the ESC is left on, it may pre-
vent the vehicle speed from increas-
ing, and result in false diagnosis.
• Turning the ESC off does not affect the ABS or brake system operation.

■ ESC OFF indicator light (comes on)
CAUTION
Driving with varying tire or wheel
sizes may cause the ESC system tomalfunction. When replacing tires,make sure they are the same size asyour 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.

Hill-start assist control (HAC)
(if equipped)
Hill start Assist Control is a comfort func-
tion. The main intend is to prevent the
vehicle from rolling backwards while driv-
ing off uphill on an inclined surface. HAC
holds the braking pressure builtup by
driver during stopping procedure for 2
seconds after releasing brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as soon
as the system detects the driver’s inten-
tion to drive off.
✽ ✽
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 ESP is off but it does not activate
when the ESP has malfunctioned. WARNING
Never press the ESC OFF button
while ESC is operating.
If the ESC is turned off while ESC is
operating, the vehicle may go out of
control.
To turn ESC off while driving, press
the ESC OFF button while driving
on a flat road surface.
WARNING
The HAC is usually activated only
for 2 seconds. The driver should be
careful from the rolling backward
causing the accident with behind
objects or human, when the driver
may feel the unintended rolling
backward while driving off on hill
due to insufficient brake hold pres-
sure built-up by driver during stop-
ping procedure.

Driving your vehicle
Vehicle stability management
(VSM) (if equipped)
This system provides further enhance-
ments to vehicle stability and steering
responses when a vehicle is driving on a
slippery road or a vehicle detected
changes in coefficient of friction between
right wheels and left wheels when brak-
ing.
VSM operation
When the VSM is in operation, ESC indi-
cator light ( ) blinks.
When the vehicle stability management
is operating properly, you can feel a slight
pulsation in the vehicle and/or abnormal
steering responses (EPS). This is only
the effect of brake and EPS control and
indicates nothing unusual.
The VSM does not operate when:
Driving on bank road such as gradientor incline
Driving rearward
ESC OFF indicator light ( ) remains on the instrument cluster
EPS indicator light remains on the instrument cluster
VSM operation off
If you press the ESC OFF button to turn
off the ESC, the VSM will also cancel and
the ESC OFF indicator light ( ) illumi-
nates.
To turn on the VSM, press the button
again. The ESC OFF indicator light goes
out.
Malfunction indicator
The VSM can be deactivated even if you
don’t cancel the VSM operation by press-
ing the ESC OFF button. It indicates that
a malfunction has been detected some-
where in the Electric Power Steering sys-
tem or VSM system. If the ESC indicator
light ( ) or EPS warning light remains
on, take your vehicle to an authorized
KIA dealer and have the system
checked.
✽ ✽ NOTICE
• The VSM is designed to function
above approximately 15 km/h (9 mph)
on curves.
• The VSM is designed to function above approximately 30 km/h (18
mph) when a vehicle is braking on a
split-mu road. The split-mu road is
made of surfaces which have different
friction forces.
WARNING
The Vehicle Stability Management
system is not a substitute for
safe driving practices but a sup-
plementary function only. It is the
responsibility of the driver to
always check the speed and the
distance to the vehicle ahead.
Always hold the steering wheel
firmly while driving.
Your vehicle is designed to acti- vate according to the driver’s
intention, even with installed
VSM. Always follow all the normal
precautions for driving at safe
speeds for the conditions –
including driving inclement
weather and on a slippery road.
Driving with varying tire or wheel sizes may cause the VSM system
to malfunction. When replacing
tires, make sure they are the
same size as your original tires.

Good braking practices
Check to be sure the parking brake is
not engaged and that the parking
brake indicator light is out before driv-
ing 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 KIA dealer for assis-
tance.
Don't coast down hills with the vehicle out of gear. This is extremely haz-
ardous. 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 driv-
ing can be dangerous because the
brakes might overheat and lose their
effectiveness. It also increases the
wear of the brake components. If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while
you slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
If your vehicle is equipped with an automatic transaxle, don't let your vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped.
Be cautious when parking on a hill. Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.
WARNING
Whenever you leave or park yourvehicle, always set the parking
brake as far as possible and fully
engage the vehicle'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 inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

537
Driving your vehicle
The cruise control system allows you to
program the vehicle to maintain a con-
stant speed without depressing the
accelerator pedal.
This system is designed to function
above approximately 40 km/h (25 mph).
✽ ✽NOTICE
During normal cruise control operation,
when the SET switch is activated or
reactivated after applying the brakes,
the cruise control will energize after
approximately 3 seconds. This delay is
normal.
To set cruise control speed:
1. Press the CRUISE ON-OFF button on
the steering wheel to turn the system
on. The CRUISE indicator light in the
instrument cluster will illuminate.
2. Accelerate to the desired speed, which must be more than 40 km/h (25 mph).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
WARNING
If the cruise control is left on,(CRUISE indicator light in the
instrument cluster illuminated)
the cruise control can be
switched on accidentally. Keep
the cruise control system off
(CRUISE indicator light OFF)
when the cruise control is not in
use, to avoid inadvertently set-
ting a speed.
Use the cruise control system only when traveling on open
highways in good weather.
Do not use the cruise control when it may not be safe to keep
the vehicle at a constant speed,
for instance, driving in heavy or
varying traffic, or on slippery
(rainy, icy or snow-covered) or
winding roads or over 6% up-hill
or down-hill roads.
(Continued)
(Continued)
Pay particular attention to thedriving conditions whenever
using the cruise control system.
Be careful when driving downhill using the cruise control system,
which may increase the vehicle
speed.
OTF050020CAUTION
During cruise-speed driving of amanual transaxle vehicle, do notshift into neutral without depress-ing the clutch pedal, since theengine will be overrevved. If thishappens, depress the clutch pedalor release the cruise control ON- OFF switch.

Remember, your vehicle does not
require 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 a very
high gear resulting in 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
speed. 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 KIA
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.

Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-tance for braking.
Avoid sudden braking or steering.
When braking with non-ABS brakes pump the brake pedal with a light up-
and-down motion until the vehicle is
stopped.
If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, or other non-slip material under the drive wheels to pro-
vide traction when stalled in ice, snow,
or mud.
Rocking the vehicle
If it is necessary to rock the vehicle to free
it from snow, sand, or mud, first turn the
steering wheel right and left to clear the
area around your front wheels. Then, shift
back and forth between 1st (First) and R
(Reverse) in vehicles equipped with a
manual transaxle or R (Reverse) and any
forward gear in vehicles equipped with an
automatic transaxle. Do not race the
engine, and spin the wheels as little as
possible. If you are still stuck after a few
tries, have the vehicle pulled out by a tow
vehicle to avoid engine overheating and
possible damage to the transaxle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING - ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
CAUTION
Prolonged rocking may causeengine overheating, transaxle dam- age or failure, and tire damage.

✽
✽
NOTICE
The ESC system (if equipped) should be
turned OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in cor-
ners, especially when roads are wet.
Ideally, corners should always be taken
under gentle acceleration. If you follow
these suggestions, tire wear will be held
to a minimum.
Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
OUN056051OMC035004
WARNING- Spinning tires
Do not spin the wheels, especially
at speeds more than 56 km/h (35
mph). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat
which could result in tire damage
that may injure bystanders.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle free
by moving it forward and backward.
Do not attempt this procedure if
people or objects are anywhere
near the vehicle. During the rocking
operation the vehicle may suddenly
move forward or backward as it
becomes unstuck, causing injury
or damage to nearby people or
objects.

Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pressures
will result in overheating and possible
failure of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire fail-
ure.
✽ ✽
NOTICE
Never exceed the maximum tire inflation
pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more fuel
than urban motoring. Do not forget to
check both the engine coolant and
engine oil.
Drive belt
A loose or damaged drive belt may over-
heat the engine.
WARNING
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
Always check the tires for proper
inflation before driving. For prop-
er tire pressures, refer to “Tires
and wheels” in section 8.
Driving on tires with no or insuffi- cient tread is dangerous. Worn-
out tires can result in loss of
vehicle control, collisions, injury,
and even death. Worn-out tires
should be replaced as soon as
possible and should never be
used for driving. Always check
the tire tread before driving your
vehicle. For further information
and tread limits, refer to “Tires
and wheels” in section 7.
