Features of your vehicle
Electric power steering (EPS)
The power steering uses a motor to
assist you in steering the vehicle. If
the engine is off or if the power steer-
ing system becomes inoperative, the
vehicle may still be steered, but it will
require increased steering effort.
The motor driven power steering is
controlled by a power steering con-
trol unit which senses the steering
wheel torque and vehicle speed to
command the motor.
The steering becomes heavier as the
vehicle’s speed increases and
becomes lighter as the vehicle’s
speed decreases for optimum steer-
ing control.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power
steering checked by an authorized
Kia dealer. If the Electric Power Steering
System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steering
wheel may require increased
steering effort. Take your vehicle to
an authorized Kia dealer and have
the vehicle checked as soon as
possible.
When you operate the steering wheel in low temperature, noise
may occur. If temperature rises, the
noise will likely disappear. This is a
normal condition.
When the vehicle is stationary, and the steering wheel is turned all the
way to the left or right continuous-
ly, the steering wheel becomes
harder to turn. The power assist is
limited to protect the motor from
overheating.
As time passes, the steering wheel
will return to its normal condition.
✽ ✽ NOTICE
The following symptoms may occur
during normal vehicle operation:
• The EPS warning light does not
illuminate.
• The steering gets heavy immedi- ately after turning the ignition
switch on. This happens as the sys-
tem performs the EPS system
diagnostics. When the diagnostics
are completed, the steering wheel
will return to its normal condition.
• A click noise may be heard from the EPS relay after the ignition
switch is turned to the ON or
LOCK (OFF) position.
• A motor noise may be heard when the vehicle is at a stop or at a low
driving speed.
• If the Electric Power Steering System does not operate normally,
the warning light will illuminate on
the instrument cluster. The steer-
ing wheel may become difficult to
control or operate abnormally.
Take your vehicle to an authorized
Kia dealer and have the vehicle
checked as soon as possible. (Continued)

Warning Light (if equipped)
This warning light illuminates:
Once you set the ignition switch or Engine Start/Stop Button to the ON
position.
- It illuminates for approximately 3seconds and then goes off.
When one or more of your tires are significantly underinflated.
For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 7.
This warning light remains on after
blinking for approximately 60 seconds
or repeats blinking and off at the
intervals of approximately 3 seconds:
When there is a malfunction with the TPMS.
In this case, have your vehicle
inspected by an authorized Kia
dealer as soon as possible.
For more details, refer to “Tire
Pressure Monitoring System
(TPMS)” in chapter 7. The TPMS cannot alert you to
severe and sudden tire damage
caused by external factors.
If you notice any vehicle instability, immediately take your foot off the
accelerator pedal, apply the brakes
gradually with light force, and slow-
ly move to a safe position off the
road.
CAUTION - Engine
damage
If the engine is not stoppedimmediately after the engine oilpressure warning light is illumi-nated and stays on while theengine is running, seriousengine damage may result.
WARNING - Low tire
pressure
Significantly low tire pressure makes the vehicle unstable
and can contribute to loss of
vehicle control and increased
braking distances.
Continued driving or low pres- sure tires will cause the tires to
overheat and fail.

✽NOTICE
When opening the windows in
humid weather air conditioning may
create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.
Air conditioning system operation tips
If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
To help reduce moisture inside of the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
Operating the air conditioning sys- tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.CAUTION - Excessive AC
When using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.Air conditioning system opera-tion may cause engine over-heating. Continue to use theblower fan but turn the air con-ditioning system off if the tem-perature gauge indicates engineoverheating.

den stop or turn the steering
wheel rapidly, loose objects
may drop on the floor and it
could interfere with the opera-
tion of the foot pedals, possibly
causing an accident.WARNING- Driving while intoxicated
Do not drive while intoxicated.
Drinking and driving is danger-
ous. Even a small amount of
alcohol will affect your reflexes,
perceptions and judgment.

To hold the vehicle on a hill use the
foot brake or the parking brake. If
the vehicle is held by applying the
accelerator pedal on a hill the
clutch and transmission will be
overheated resulting in damage.
At this time, a warning message
will appear on the LCD display and
you may feel a vibration. If the clutch becomes overheated
by excessive use of the clutch to
hold on a hill, you may notice a
shuddering feeling and a blinking
display on the instrument cluster.
When this occurs, the clutch is dis-
abled until the clutch cools to nor-
mal temperatures. If this occurs,
pull over to a safe location, shift
into P (Park) and apply the foot
brake with the engine on for a cer-
tain time until the warning on the
LCD screen disappears.
If the LCD warning is active, the foot brake must be applied.
Ignoring the warnings can lead to damage to the transmission.
If the display continues to blink, for your safety, we recommend that
you contact an authorized Kia
dealer.
Under certain conditions such asrepeated launch on steep grades,
the clutch in the transmission could
overheat.

Driving your vehicle
When the clutch is overheated, the
safe protection mode engages. If
the safe protection mode engages,
the gear position indicator on the
cluster blinks with a chime sound.
At this time, a warning message
will appear on the LCD display and
driving may not be smooth.
If you ignore this warning, the driv-
ing condition may become worse.
To return the normal driving condi-
tion, stop the vehicle and apply the
foot brake for a few minutes before
driving off.
Gear shifts may be more notice- able than a conventional automatic
transmission. This is a normal
characteristic of this type of dual
clutch transmission.
An overheated Dual clutch trans- mission may change the gear shift-
ing characteristics, and will illumi-
nate a warning message on the
LCD display if the kickdown mech-
anism is excessively used. Do not use the kickdown mecha-
nism to return to normal driving.
Also, temporarily stop the vehicle
at a safe location, when the warn-
ing message illuminates on the
LCD display.
During the first 1,500km (1,000miles), you may feel that the
vehicle may not be smooth when
accelerating at low speed. During
this break-in period, the shift quali-
ty and performance of your new
vehicle is continuously optimized.
Always come to a complete stop before shifting into D (Drive) or R
(Reverse).
Do not put the shift lever in N (Neutral) while driving. The indicator in the instrument clus-
ter displays the shift lever position
when the ignition switch is in the ON
position.
P (Park)
Always come to a complete stop
before shifting into P (Park).
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
The shift lever must be in P (Park)
before turning the engine off.
CAUTION
- Holding the Vehicle Using
Accelerator Pedal
Do not attempt to hold yourvehicle on a hill by applying theaccelerator pedal. This cancause your clutch and transmis-sion to be damaged as a resultof overheating.
WARNING
Shifting into P (Park) while the vehicle is in motion may
cause you to lose control of
the vehicle.
After the vehicle has stopped, always make sure the shift
lever is in P (Park), apply the
parking brake, and turn the
engine off.
Do not use the P (Park) position in place of the parking brake.

Driving your vehicle
Good driving practices
Never move the shift lever from P(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in motion.
Be sure the car is completely stopped before you attempt to shift
into R (Reverse) or D (Drive).
Never take the car out of gear and coast down a hill. This may be
extremely hazardous. Always leave
the car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and mal-
function. Instead, when you are
driving down a long hill, slow down
and shift to a lower gear. When you
do this, engine braking will help
slow the car.
Slow down before shifting to a lower gear. Otherwise, the lower
gear may not be engaged. Always use the parking brake. Do
not depend on placing the
transaxle in P (Park) to keep the
car from moving.
Exercise extreme caution when driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
the vehicle to go out of control.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator pedal.
✽ ✽ NOTICE- Kickdown
Mechanism
Use the kickdown mechanism for
maximum acceleration. Depress the
accelerator pedal beyond the pres-
sure point. The dual clutch trans-
mission will shift to a lower gear
depending on the engine speed.
Moving up a steep grade from astanding start
To move up a steep grade from a
standing start, depress the brake
pedal, shift the shift lever to D
(Drive). Select the appropriate gear
depending on load weight and steep-
ness of the grade, and release the
parking brake. Depress the accelera-
tor gradually while releasing the
service brakes.
