LANE KEEPING ASSIST SYSTEM (LKAS) (IF EQUIPPED)
05'4
The Lane Keeping Assist System de‐
tects lane markers on the road, and as‐ sists the driver’s steering to help keep
the vehicle between lanes. When the system detects the vehicle
straying from its lane, it alerts the driv‐
er with a visual and audible warning, while applying a slight counter steering
torque, trying to prevent the vehicle
from moving out of its lane.
WARNING
•The steering wheel is not continu‐ously controlled so if the vehiclespeed is very fast when leaving alane the vehicle may not be con‐trolled by the system.
•The operation of the LKAS can beaffected by several factors (in‐cluding environmental conditions).It is the responsibility of the driverto pay attention to the roadwayand to maintain the vehicle in itslane at all times.
•Do not steer the steering wheelsuddenly when the steering wheelis being assisted by the system.

•LKAS prevents the driver frommoving out of the lane uninten‐tionally by assisting the driver'ssteering. However, the drivershould not solely rely on the sys‐tem but always pay attention onthe steering wheel to stay in thelane.
•Always check the road conditionand surroundings and be cautiouswhen the system cancels, doesnot operate or malfunctions.
•Do not place any accessories,stickers or tint the windshield nearthe rearview mirror.
•The system detects lane markersand controls the steering wheel bya camera, therefore, if the lanemarkers are hard to detect, thesystem may not work properly.Please refer to L

•Do not place objects on the dash‐board that reflects light such asmirrors, white paper, etc. The sys‐tem may malfunction if the sun‐light is reflected.
•Loud audio sounds may interferewith the passenger from hearingwarning chimes.
•Always have your hands on thesteering wheel while the LKASsystem is activated. If you contin‐ue to drive with your hands off thesteering wheel after the "Hand on"warning, the system will turn offautomatically.
•If you drive very fast, the vehiclemay stray out of the lane. Alwaysbe cautious when using the sys‐tem.
•When you tow the trailer, makesure that you turn off LKAS func‐tion.

• LDW is generated when the vehicle isabout to cross the line.
Active LKA
• LKAS operates for a vehicle to keepthe region of lane center more effi‐
ciently.
• The steering assistance is activated more frequently and earlier than
standard LKA.
• LDW is generated when the vehicle is about to cross the line.

• Use your air conditioning sparingly.The air conditioning system is oper‐
ated by engine power so your fuel economy is reduced when you use it.
• Open windows at high speeds can re‐ duce 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
condition is important both for econo‐
my and safety. Therefore, we recom‐ mend that the system be serviced by
an authorized Kia dealer.
WARNING
nEngine off during motion
Never turn the engine off to coastdown hills or anytime the vehicle isin motion. The power steering andpower brakes will not function prop‐erly without the engine running. In‐stead, keep the engine on and down‐shift to an appropriate gear for en‐gine braking effect. In addition, turn‐

ing off the engine start/stop buttonwhile driving could engage the steer‐ing wheel lock (if equipped) resultingin loss of vehicle steering whichcould cause serious injury or death.

SPECIAL DRIVING CONDITIONS
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.
WARNING
nABS
Do not pump the brake pedal on avehicle equipped with ABS.
• If stalled in snow, mud, or sand, use second gear. Accelerate slowly to
avoid spinning the drive wheels.
• Use sand, rock salt, tire chains, or other non-slip material under the
drive wheels to provide traction when
stalled in ice, snow, or mud.
WARNING
nDownshifting
Downshifting with an automatictransaxle, while driving on slipperysurfaces can cause an accident. Thesudden change in tire speed couldcause the tires to skid. Be carefulwhen downshifting on slippery sur‐faces.
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 be‐ tween 1 (First) and R (Reverse) in vehi‐
cles equipped with a manual transaxle
or R (Reverse) and any forward gear in vehicles equipped with an Automatic
Transaxle / Dual clutch transmission. 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.
CAUTION
Prolonged rocking may cause engineover-heating, transaxle damage orfailure, and tire damage.
WARNING
nSpinning tires
Do not spin the wheels, especially atspeeds more than 56 km/h(35 mph). Spinning the wheels athigh speeds when the vehicle is sta‐tionary could cause a tire to over‐heat which could result in tire dam‐age that may injure bystanders.
NOTICE
The ESC system should be turned
OFF prior to rocking the vehicle.

Use approved window washer
anti-freeze in system
To keep the water in the window wash‐er system from freezing, add an ap‐
proved window washer anti-freeze sol‐
ution in accordance with instructions on the container. Window washer anti-
freeze is available from an authorized
Kia dealer and most auto parts outlets. Do not use engine coolant or other
types of anti-freeze as these may
damage the paint finish.
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged posi‐ tion. This is most likely to happen when
there is an accumulation of snow or ice
around or near the rear brakes or if the brakes are wet. If there is a risk the
parking brake may freeze, apply it only
temporarily while you put the shift lev‐ er in P (Automatic Transaxle / Dual
clutch transmission) or in first or re‐
verse gear (manual transaxle) and block
the rear wheels so the vehicle cannot roll. Then release the parking brake.
Don't let ice and snow
accumulate underneath
Under some conditions, snow and ice can build up under the fenders and in‐
terfere with the steering. When driving
in severe winter conditions where this may happen, you should periodically
check underneath the vehicle to be sure
the movement of the front wheels and the steering components is not ob‐
structed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropriate emergency equipment. Some of the
items you may want to carry include
tire chains, tow straps or chains, flash‐ light, emergency flares, sand, shovel,
jumper cables, window scraper, gloves,
ground cloth, coveralls, blanket, etc.

It is possible that some tires, especially
with larger punctures or damage to the sidewall, cannot be sealed completely.
Air pressure loss in the tire may ad‐
versely affect tire performance.
For this reason, you should avoid
abrupt steering or other driving ma‐ neuvers, especially if the vehicle is
heavily loaded or if a trailer is in use.
The TMK is not designed or intended as
a permanent tire repair method and is to be used for one tire only.This instruction shows you step by step
how to temporarily seal the puncture
simply and reliably.
