Driving your vehicle
For smooth operation, depress thebrake pedal when shifting from N(Neutral) to a forward or reversegear.
When stopped on an incline, do not
hold the vehicle with engine power.
Use the service brake or the parking
brake.
Transaxle ranges
The indicator light in the instrument
cluster displays the shift lever posi-
tion when the ignition switch is in the
ON position.
P (Park)
Always come to a complete stop
before shifting into P (Park). This
position locks the transaxle and pre-
vents the front wheels from rotating.
Shifting into P (Park) while the vehi-
cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.CAUTION - Transaxle
To avoid damage to yourtransaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on. The transaxle may bedamaged if you shift into P(Park) while the vehicle is inmotion.
WARNING- Automatic
Transaxle
Before leaving the driver's seat,
always make sure the shift lever
is engaged in P (Park), set the
parking brake fully and shut the
engine off. Unexpected and
sudden vehicle movement may
occur if these precautions are
not followed.

Driving your vehicle
Up (+) : Push the lever forwardonce to shift up one gear.
Down (-) : Pull the lever backwards once to shift down one
gear.
In sports mode, the driver must execute upshifts in accordance
with road conditions, taking care to
keep the engine speed below the
red zone.
In sports mode, only the 6 forward gears can be selected. To reverse
or park the vehicle, move the shift
lever to the R (Reverse) or P (Park)
position as required.
In sports mode, downshifts are made automatically when the vehi-
cle slows down. When the vehicle
stops, 1st gear is automatically
selected.
In sports mode, when the engine rpm approaches the red zone shift
points are varied to upshift auto-
matically. To maintain the required levels of
vehicle performance and safety,
the system may not execute cer-
tain gearshifts when the shift lever
is operated.
When driving on a slippery road, push the shift lever forward into the
+(up) position. This causes the
transaxle to shift into the 2nd gear
which is better for smooth driving
on a slippery road. Push the shift
lever to the -(down) side to shift
back to the 1st gear.Paddle shifter (if equipped)
The paddle shifter is available when
the shift lever is in the D position or
the sport mode.

With the shift lever in the D position
The paddle shifter can operate when
the vehicle speed is more than 10
km/h (6.2 mph).
Pull the [+] or [-] paddle shifter once
to shift up or down one gear and the
system changes from automatic
mode to manual mode.
If the vehicle speed is lower than
10km/h (6.2 mph), if you depress the
accelerator pedal for more than 5
seconds or if you shift the shift lever
from D to sports mode and shift it
from sports mode to D again, the
system change from manual mode to
automatic mode.
With the shift lever in the sports mode
Pull the [+] or [-] paddle shifter once
to shift up or down one gear.
If you pull the [+] and [-] paddle
shifters at the same time, you can't
shift the gear.Shift lock system
For your safety, the automatic
transaxle has a shift lock system
which prevents shifting the transaxle
out of P (Park) unless the brake
pedal is depressed.
To shift the transaxle from P (Park)
into R (Reverse):
1.Depress and hold the brake pedal.
2.Start the engine or turn the ignition
switch to the ON position.
3.Move the shift lever.
If the brake pedal is repeatedly
depressed and released with the
shift lever in the P (Park) position, a
chattering noise near the shift lever
may be heard. This is a normal con-
dition. Shift-lock override (with smart key
system)
If the shift lever cannot be moved
from the P (Park) or N (Neutral) posi-
tion into the R (Reverse) position
with the brake pedal depressed, con-
tinue depressing the brake, then do
the following:
1.Carefully remove the cap (1) cover-
ing the shift-lock access hole.
2.Insert a screwdriver into the access hole and press down on
the screwdriver.
3.Move the shift lever.
4.Have your vehicle inspected by an authorized Kia dealer immediately.
WARNING - Shifting from
park
Always fully depress the brake
pedal before and while shifting
out of the P (Park) position into
another position to avoid inad-
vertent motion of the vehicle.

BRAKE SYSTEM
Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces. Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
WARNING - Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
CAUTION - Brake pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

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.

Driving your vehicle
The ABS continuously senses the
speed of the wheels. If the wheels
are going to lock, the ABS system
repeatedly modulates the hydraulic
brake pressure to the wheels.
When you apply your brakes under
conditions which may lock the
wheels, you may hear a “tik-tik’’
sound from the brakes, or feel a cor-
responding sensation in the brake
pedal. This is normal and it means
your ABS is active.
In order to obtain the maximum ben-
efit from your ABS in an emergency
situation, do not attempt to modulate
your brake pressure and do not try to
pump your brakes. Press your brake
pedal as hard as possible or as hard
as the situation allows the ABS to
control the force being delivered to
the brakes.✽ ✽NOTICE
A click sound may be heard in the
engine compartment when the vehi-
cle begins to move after the engine is
started. These conditions are normal
and indicate that the anti-lock brake
system is functioning properly.
Even with the anti-lock brake sys-
tem, your vehicle still requires suf-
ficient stopping distance. Always
maintain a safe distance from the
vehicle in front of you.
Always slow down when cornering. The anti-lock brake system cannot
prevent accidents resulting from
excessive speeds.
On loose or uneven road surfaces, operation of the anti-lock brake
system may result in a longer stop-
ping distance than for vehicles
equipped with a conventional
brake system. The ABS warning light will stay on for
approximately 3 seconds after the
ignition switch is ON. During that
time, the ABS will go through self-
diagnosis and the light will go off if
everything is normal. If the light stays
on, you may have a problem with
your ABS but your regular brakes will
work normally. Contact an authorized
Kia dealer as soon as possible.

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.

ESC OFF state
This car has 2 kinds of ESC
off states.
If the engine stops when
ESC is off, ESC remains off.
Upon restarting the engine,
the ESC will automatically
turn on again.
ESC off state 1
To cancel ESC operation, press the
ESC OFF button (ESC OFF )
shortly (ESC OFF indicator light
(ESC OFF ) illuminates). At this
state, the engine control function
does not operate. It means the trac-
tion control function does not oper-
ate. Brake control function only oper-
ates.
