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 ).
CRUISE CONTROL SYSTEM (IF EQUIPPED)
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.

WARNING
The Blind Spot Detection
System with Lane Change
Assist and Rear Cross Traffic
Alert is not a substitute for
proper and safe lane changing
procedures. Always drive safely
and use caution when changing
lanes. The Blind Spot Detection
System may not detect every
object alongside the vehicle.
CAUTION
The system may not work
properly if the bumper hasbeen replaced or if a repairwork has been done near thesensor.
The detection area differs according to the roads width.If the road is narrow the sys-tem may detect other vehiclesin the next lane.
On the contrary, if the road is very wide the system may notdetect other vehicles.
The system may turn off due to strong electromagneticwaves.

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 placing 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 avoided by shifting at
the recommended speed. Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is reduced by cross- winds and headwinds. To help off-
set some of this loss, slow down
when driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off during
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 running. In addition,
turning off the ignition while
driving could engage the steer-
ing wheel lock resulting in loss
of vehicle steering. Keep the
engine on and downshift to an
appropriate gear for engine
braking effect.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extradistance 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. Do not pump the brake pedal on a
vehicle equipped with ABS.
If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non- slip material under the drive
wheels to provide 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 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 vehi-
cle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transaxle.
The ESC system should be turned
OFF prior to rocking the vehicle.
SPECIAL DRIVING CONDITIONS
WARNING - Downshifting
Do not downshift with an auto-
matic transaxle while driving on
slippery surfaces. The sudden
change in tire speed could
cause the tires to skid and
result in an accident.
CAUTION - Vehicle rocking
Prolonged rocking may causeengine overheating, transaxledamage or failure, and tire dam-age.

Smooth cornering
Avoid braking or gear changing in
corners, 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 dis-
tance between you and other vehi-
cles, as it may be more difficult to
see at night, especially in areas
where there may not be any street
lights.
OBH058035LOMC035004
WARNING- Sudden
vehicle movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as
it becomes unstuck.
CAUTION - Spinning tires
Do not spin the wheels, espe- cially at speeds more than 56km/h (35 mph). Spinning thewheels at high speeds when thevehicle is stationary couldcause a tire to overheat whichcould result in tire damage.

ROAD WARNING
Hazard warning flasher
The hazard warning flasher serves
as a warning to other drivers to exer-
cise extreme caution when
approaching, overtaking, or passing
your vehicle.It should be used whenever emer-
gency repairs are being made or
when the vehicle is stopped near the
edge of a roadway.
Depress the flasher switch with the
ignition switch in any position. The
flasher switch is located in the center
console switch panel. All turn signal
lights will flash simultaneously.
• The hazard warning flasher oper-
ates whether your vehicle is run-
ning or not.
The turn signals do not work when the hazard flasher is on.
Care must be taken when using the hazard warning flasher while
the vehicle is being towed.

IF THE ENGINE WILL NOT START
If the engine doesn't turn over
or turns over slowly
1.If your vehicle has an automatictransaxle, be sure the shift lever is
in N (Neutral) or P (Park) and the
emergency brake is set.
2.Check the battery connections to be sure they are clean and tight.
3.Turn on the interior light. If the light dims or goes out when you operate
the starter, the battery is dis-
charged.
4.Check the starter connections to be sure they are securely tight-
ened.
5.Do not push or pull the vehicle to start it. See instructions for "Jump
starting".
If engine turns over normally
but does not start
1.Check fuel level.
2.With the ignition switch in theLOCK position, check all connec-
tors at the ignition coil and spark
plugs. Reconnect any that may be
disconnected or loose.
3.Check the fuel line in the engine compartment.
4.If the engine still does not start, call an authorized Kia dealer or seek
other qualified assistance.
WARNING - Push/pull
start
Do not push or pull the vehicle
to start it. Push or pull starting
may cause the catalytic con-
verter to overload and create a
fire hazard.
