If the parking brake does not release or
does not release all the way, have the
system checked by an authorized Kia
dealer.
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will illuminate when the
parking brake is applied with the ignition
switch in the START or ON position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released while
the engine is running, there may be a
malfunction in the brake system.
Immediate attention is necessary.
If at all possible, stop driving the vehicle
immediately. If that is not possible, use
extreme caution while operating the vehi-
cle and only continue to drive the vehicle
until you can reach a safe location or
repair shop.Anti-lock brake system (ABS)
(if equipped)
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous driving maneuvers. Even
though vehicle control is improved
during emergency braking, always
maintain a safe distance between
you and objects ahead. Vehicle
speeds should always be reduced
during extreme road conditions.
The braking distance for vehicles
equipped with an anti-lock braking
system (Electronic Stability Control
System) may be longer than for
those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-coveredroads.
On roads where the road surface is pitted or has different surface
height.

WARNING
To prevent unintentional move-ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
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.

527
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 allows the ABS to control the force
being delivered to the brakes.
✽ ✽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 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.
(Continued)
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.
W-78
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 Kia dealer as soonas possible.

NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and 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 has malfunctioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control (ESC)
The Electronic Stability control (ESC)
system is designed to stabilize the vehicle
during cornering maneuvers. ESC checks
where you are steering and where the
vehicle is actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine management
system to stabilize the vehicle.
CAUTION
When you drive on a road with
poor traction, such as an icy road,and operated your brakes contin-uously, the ABS will be activecontinuously and the ABS warn- ing light may illuminate. Pull yourvehicle over to a safe place andstop the engine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorized Kia dealer as soon aspossible.

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.

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.

Active ECO operation
Active ECO helps improve fuel efficiency
by controlling the engine and transaxle.
But fuel-efficiency can be changed by the
driver's driving habits and road condi-
tions.
When the Active ECO button is
pressed the ECO indicator (green) will
illuminate to show that the Active ECO
is operating.
When the Active ECO is activated, it does not turn off even though the
engine is restarted again. To turn off
the system, press the active ECO but-
ton again.
If Active ECO is turned off, it will return to the normal mode.
Limitation of Active ECO operation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there is
no change in the ECO indicator.
When the coolant temperature is low:
The system will be limited until engine
performance becomes normal.
When driving up a hill: The system will be limited to gain
power when driving uphill because the
engine torque is restricted.
When using sports mode: The system will be limited according to
the shift location.
When the accelerator pedal is deeply pressed for a few seconds:
The system will be limited, Judging
that the driver wants to speed up.

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.

Driving your vehicle
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
miles (kilometers) you can get from a gal-
lon (liter) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary braking. This also reduces
brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your vehicle
uses. Driving at a moderate speed,
especially on the highway, is one of the
most effective ways to reduce fuel con-
sumption. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see section 7 for details).
Keep your vehicle clean. For maximum service, your vehicle should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the vehicle. This
extra weight can result in increased
fuel consumption and also contribute
to corrosion.
Travel lightly. Don't carry unnecessary weight in your vehicle. Weight reduces
fuel economy.
Don't let the engine idle longer than necessary. If you are waiting (and not
in traffic), turn off your engine and
restart only when you're ready to go.
ECONOMICAL OPERATION

Driving your vehicle

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.
