fect ABS or brake system opera‐
tion.
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 be‐
tween right wheels and left wheels
when braking.
VSM operation
When the VSM is in operation, • ESC (Electronic Stability Control) ()
light will blink.
• The steering wheel may be control‐ led.
When the vehicle stability management is operating properly, you can feel a
slight pulsation in the vehicle. This is
only the effect of brake control and in‐ dicates nothing unusual.
The VSM does not operate when:
• Driving on bank road such as gradient or incline
• Driving rearward
• ESC OFF indicator light (
) remains
on the instrument cluster

off the ESC, the VSM will also cancel and the ESC OFF indicator light (
) illu‐
minates.
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 pressing the ESC OFF button. It indi‐
cates that a malfunction has been de‐
tected somewhere in the EPS (Elec‐ tronic Power Steering) system or VSM
system. If the ESC indicator light (
) or
EPS warning light remains on, we rec‐
ommend that the system be checked by an authorized Kia dealer.
NOTICE
•The VSM is designed to function
above approximately 22 km/h
(13 mph) on curves.
(Continued)
(Continued)
•The VSM is designed to function
above approximately 10 km/h
(6 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 Managementsystem is not a substitute for safedriving practices but a supplemen‐tary function only. It is the respon‐sibility of the driver to alwayscheck the speed and the distanceto the vehicle ahead. Always holdthe steering wheel firmly whiledriving.
•Your vehicle is designed to activateaccording to the driver’s intention,even with the VSM installed. Al‐ways follow all the normal precau‐tions for driving at safe speed forthe conditions – including driving ininclement weather and on a slip‐pery road.
(Continued)
(Continued)
•Driving with varying tire or wheelsizes may cause the VSM systemto malfunction. When replacingtires, make sure they are thesame size as your original tires.
Hill-start assist control (HAC) (if
equipped)
A vehicle has the tendency to slip back
on a steep hill when it starts to go af‐ ter stopping. The Hill-start Assist Con‐
trol (HAC) prevents the vehicle from
slipping back by operating the brakes automatically for about 1~2 seconds.
The brakes are released when the ac‐
celerator pedal is depressed or after about 1~2 seconds.
WARNING
The HAC is activated only for about1~2 seconds, so when the vehicle isstarting off always depress the ac‐celerator pedal.

WINTER DRIVING
Severe weather conditions in the winter result in greater wear and other prob‐
lems. To minimize the problems of win‐
ter driving, you should follow these suggestions: ❈ Snow tires and tire chains for the
national language (Icelandic, Bul‐
garian) see Chapter 11, Appendix.
Snowy or icy conditions
To drive your vehicle in deep snow, it
may be necessary to use snow tires or to install tire chains on your tires. If
snow tires are needed, it is necessary
to select tires equivalent in size and type of the original equipment tires.
Failure to do so may adversely affect
the safety and handling of your vehicle. Furthermore, speeding, rapid accelera‐
tion, sudden brake applications, and
sharp turns are potentially very haz‐ ardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake ap‐
plications on snowy or icy roads may cause skids to occur. You need to keep
sufficient distance between the vehicle
in operation in front and your vehicle. Also, apply the brake gently. It should
be noted that installing tire chains on
the tire will provide a greater driving force, but will not prevent side skids.
NOTICE
Tire chains are not legal in all coun‐
tries. Check the country laws before
fitting tire chains.
Snow tires
If you mount snow tires on your vehi‐
cle, make sure they are radial tires of the same size and load range as the
original tires. Mount snow tires on all
four wheels to balance your vehicle’s handling in all weather conditions. Keep
in mind that the traction provided by
snow tires on dry roads may not be as high as your vehicle's original equip‐
ment tires. You should drive cautiously
even when the roads are clear. Check with the tire dealer for maximum
speed recommendations.
Do not install studded tires without
first checking local, state and municipal regulations for possible restrictions
against their use.
WARNING
nSnow tire size
Snow tires should be equivalent insize and type to the vehicle's stand‐ard tires. Otherwise, the safety andhandling of your vehicle may be ad‐versely affected.

Tire chains
Since the sidewalls of radial tires are
thinner, they can be damaged by mounting some types of snow chains
on them. Therefore, the use of snow
tires is recommended instead of snow chains. Do not mount tire chains on ve‐
hicles equipped with aluminum wheels;
snow chains may cause damage to the wheels. If snow chains must be used,
use wire-type chains with a thickness
of less than 12 mm (0.47 in). Damage
to your vehicle caused by improper
snow chain use is not covered by your
vehicle manufacturers warranty.
Install tire chains only on the front tires.
CAUTION
•Make sure the snow chains are thecorrect size and type for yourtires. Incorrect snow chains cancause damage to the vehicle bodyand suspension and may not becovered by your vehicle manufac‐turer warranty. Also, the snowchain connecting hooks may bedamaged from contacting vehiclecomponents causing the snowchains to come loose from the tire.Make sure the snow chains areSAE class "S" certified.
•Always check chain installation forproper mounting after driving ap‐proximately 0.5 to 1 km (0.3 to 0.6miles) to ensure safe mounting.Retighten or remount the chains ifthey are loose.
Chain installation
When installing chains, follow the man‐
ufacturer's instructions and mount them as tightly as you can. Drive slowly
with chains installed. If you hear the
chains contacting the body or chassis, stop and tighten them. If they still
make contact, slow down until it stops.
Remove the chains as soon as you be‐ gin driving on cleared roads.
WARNING
nMounting chains
When mounting snow chains, parkthe vehicle on level ground awayfrom traffic. Turn on the vehicleHazard Warning flashers and place atriangular emergency warning devicebehind the vehicle if available. Al‐ways place the vehicle in P (Park),apply the parking brake and turn offthe engine before installing snowchains.
WARNING
nTire chains
•The use of chains may adverselyaffect vehicle handling.
•Do not exceed 30 km/h (20 mph)or the chain manufacturer’s rec‐ommended speed limit, whicheveris lower.

CAUTION
If the inflation pressure is not main‐tained, drive the vehicle a secondtime, refer to Distributing the seal‐ant. Then repeat steps 1 to 4.Use of the TMK may be ineffectualfor tire damage larger than approxi‐mately 4 mm (0.16 in).We recommend that you contact anauthorized Kia dealer if the tire can‐not be made roadworthy with theTire Mobility Kit.
WARNING
The tire inflation pressure must beat least 200 kPa (29 psi). If it is not,do not continue driving.Call for road side service or towing.
Notes on the safe use of the
Tire Mobility Kit
• Park your car at the side of the roadso that you can work with the TMK
away from moving traffic. Place your warning triangle in a prominent place
to make passing vehicles aware of
your location. • To be sure your vehicle will not move,
even when you're on fairly level
ground, always set your parking brake.
• Only use the TMK for sealing/inflation passenger car tires. Do not use on
motorcycles, bicycles or any other
type of tires.
• Do not remove any foreign objects such as nails or screws -that have
penetrated the tire.
• Before using the TMK, read the pre‐ cautionary advice printed on the seal‐ ant bottle!
• Provided the car is outdoors, leave the engine running. Otherwise oper‐
ating the compressor may eventually
drain the car battery.
• Never leave the TMK unattended while it is being used.
• Do not leave the compressor running for more than 10 min. at a time or it
may overheat.
• Do not use the TMK if the ambient temperature is below -30°C (-22°F).
• When the tire and wheel are dam‐ aged, do not use Tire Mobility Kit foryour safety.

NOTICE
We recommend that when replacing
tires, use the same originally sup‐
plied with the vehicles.
If not, that affects driving perform‐
ance.
CAUTION
When replacing the tires, recheckand tighten the wheel nuts afterdriving about 50 km (31 miles) andrecheck after driving about 1,000 km(620 miles).If the steering wheel shakes or thevehicle vibrates while driving, thetire is out of balance. Align the tirebalance. If the problem is not solved,we recommend that you contact anauthorized Kia dealer.
WARNING
nReplacing tires
(Continued)
(Continued)
To reduce the chance of serious orfatal injuries from an accidentcaused by tire failure or loss of vehi‐cle control:•Replace tires that are worn, showuneven wear, or are damaged.Worn tires can cause loss of brak‐ing effectiveness, steering control,and traction.
•Do not drive your vehicle with toolittle or too much pressure in yourtires. This can lead to uneven wearand tire failure.
•When replacing tires, never mix ra‐dial and bias-ply tires on the samecar. You must replace all tires (in‐cluding the spare) if moving fromradial to bias-ply tires.
•Using tires and wheels other thanthe recommended sizes couldcause unusual handling character‐istics and poor vehicle control, re‐sulting in a serious accident.
(Continued)
(Continued)
•Wheels that do not meet Kia’sspecifications may fit poorly andresult in damage to the vehicle orunusual handling and poor vehiclecontrol.
•The ABS works by comparing thespeed of the wheels. The tire sizeaffects wheel speed. When replac‐ing tires, all 4 tires must use thesame size originally supplied withthe vehicle. Using tires of a differ‐ent size can cause the ABS (Anti-lock Brake System) and ESC (Elec‐tronic Stability Control) to work ir‐regularly.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new wheels are equivalent to the original factory
units in diameter, rim width and offset.
