Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will illumi-
nate 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 nec-
essary. If at all possible, stop driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location or repair
shop.
Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
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 vehicle should be driven at
reduced speeds in the following cir-
cumstances:
When driving on rough, gravel or
snow-covered roads
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
the stopping distance for your vehi-
cle.

When you drive on a road with
poor traction, such as an icy road,
and operated your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light is off, then your ABS
is normal. Otherwise, you may
have a problem with the ABS.
Contact an authorized Kia dealer
as soon as 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 mal-
functioned.
• 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 stabi-
lize 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 manage-
ment system to stabilize the vehicle.
Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers
and hydroplaning on wet surfaces
can still result in serious accidents.

WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.

The Vehicle Stability Management
system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility 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 react 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 in
inclement weather and on a slip-
pery road.Good braking practices
Check to be sure the parking brakeis not engaged and that the park-
ing brake indicator light is out
before driving 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 extreme-
ly hazardous. 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.
WARNING- Tire/Wheel
size
When replacing tires and
wheels, make sure they are the
same size as the original tires
and wheels installed. Driving
with varying tire or wheel sizes
may diminish any supplemental
safety benefits of the VSM sys-
tem.
WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.

The cruise control system allows you
to program the vehicle to maintain a
constant speed without depressing
the accelerator pedal.
This system is designed to function
above approximately 40 km/h (25
mph).
If the cruise control is left on,
(CRUISE indicator light in the instru-
ment cluster illuminated) the cruise
control can be switched on acciden-
tally. Keep the cruise control system
off (CRUISE indicator light OFF)
when the cruise control is not in use,
to avoid inadvertently setting a
speed.
Use the cruise control system only
when traveling on open highways in
good weather.
Do not use the cruise control when
driving in heavy or varying traffic, or
on slippery (rainy, icy or snow-cov-
ered) or winding roads or over 6%
up-hill or down-hill roads.✽ ✽
NOTICE
• During normal cruise control
operation, when the SET switch is
activated or reactivated after
applying the brakes, the cruise
control will energize after approx-
imately 3 seconds. This delay is
normal.
• To activate cruise control, depress the brake pedal at least once after
turning the ignition switch to the
ON position or starting the engine.
This is to check if the brake switch
which is important part to cancel
cruise control is in normal condi-
tion.
To set cruise control speed:
1.Press the CRUISE button on the
steering wheel to turn the system
on. The CRUISE indicator light in
the instrument cluster will illumi-
nate.
2.Accelerate to the desired speed, which must be more than 40 km/h
(25 mph ).

WARNING - Misuse of
Cruise Control
Do not use cruise control if the
traffic situation does not allow
you to drive safely at a constant
speed and with sufficient dis-
tance to the vehicle in front.

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 gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary 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 consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 7 for details).
Keep your vehicle clean. For maxi- mum 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 unneces- sary 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.
