If the EPB is applied while Auto Hold is
activated because of ESC (Electronic Stability Control) signal, a warning will
sound and a message will appear.
EPB malfunction indicator (if
equipped)
0+'
This warning light illuminates if the en‐
gine start/stop button is changed to the ON position and goes off in approxi‐
mately 3 seconds if the system is oper‐
ation normally. If the EPB malfunction indicator re‐
mains on, comes on while driving, or
does not come on when the ignition
switch or the engine start/stop button is changed to the ON position, this indi‐
cates that the EPB may have malfunc‐
tioned.
If this occurs, we recommend that the system be checked by an authorized
Kia dealer.
The EPB malfunction indicator may illu‐
minate when the ESC indicator comes on to indicate that the ESC is not work‐
ing properly, but it does not indicate a
malfunction of the EPB.
CAUTION
•The EPB warning light may illumi‐nate if the EPB switch operatesabnormally. Shut the engine offand turn it on again after a fewminutes. The warning light will gooff and the EPB switch will oper‐ate normally. However, if the EPBwarning light is still on, we recom‐mend that the system be checkedby an authorized Kia dealer.

•If the parking brake warning lightdoes not illuminate or blinks eventhough the EPB switch was pulledup, the EPB is not applied.
•If the parking brake warning lightblinks when the EPB warning lightis on, press the switch, then pull itup. Once more press it back to itsoriginal position and pull it back up.If the EPB warning does not gooff, we recommend that the sys‐tem be checked by an authorizedKia dealer.
Emergency braking
If there is a problem with the brake
pedal while driving, emergency braking is possible by pulling up and holding the
EPB switch. Braking is possible only
while you are holding the EPB switch.
WARNING
Do not operate the parking brakewhile the vehicle is moving except inan emergency situation.
NOTICE
During emergency braking by the
EPB, the parking brake warning light
will illuminate to indicate that the
system is operating.
CAUTION
If you continuously notice a noise orburning smell when the EPB is usedfor emergency braking, we recom‐mend that the system be checkedby an authorized Kia dealer.
When the EPB (Electronic ParkingBrake) does not release
If the EPB does not release normally, we recommend that you contact an au‐
thorized Kia dealer by loading the vehi‐
cle on a flatbed tow truck and have the system checked.
AUTO HOLD (if equipped)
The Auto Hold maintains the vehicle in
a standstill even though the brake ped‐ al is not depressed after the driver
brings the vehicle to a complete stop by
depressing the brake pedal.

ESC operation
ESC ON condition
-• When the engine start/stopbutton is turned ON, ESC
and ESC OFF indicator lights
illuminate for approximate‐
ly 3 seconds, then ESC is turned on.
• Press the ESC OFF button for at least half a second
after turning the ignition
ON to turn ESC off. (ESC
OFF indicator will illumi‐
nate). To turn the ESC on, press the ESC OFF button
(ESC OFF indicator light will
go off).
• When starting the engine, you may hear a slight tick‐
ing sound. This is the ESC
performing an automatic
system self-check and does not indicate a problem.
When operating
When the ESC is in operation, ESC indicator light blinks. • When the Electronic Stabili‐ ty Control is operating
properly, you can feel a
slight pulsation in the vehi‐
cle. This is only the effect of brake control and indi‐
cates nothing unusual.
• When moving out of the mud or slippery road, the
engine rpm (revolution per
minute) may not increase
even if you press the accel‐ erator pedal deeply. This is
to maintain the stability
and traction of the vehicle
and does not indicate a
problem.
ESC operation off
ESC OFF state
This car has 2 kinds of ESC off states.If the engine stops when ESC

cels the system setting.
The warning light illuminates on the LCD display, when youcancel the AEB system.
The driver can monitor the AEBON/OFF status on the LCD display.

ECONOMICAL OPERATION
Your vehicle's fuel economy depends mainly on your style of driving, where
you drive and when you drive.
Each of these factors affects how
many kilometers (miles) you can get from a liter (gallon) of fuel. To operate
your vehicle as economically as possi‐
ble, use the following driving sugges‐ tions to help save money in both fuel
and repairs: • Drive smoothly. Accelerate at a mod‐ erate rate. Do not make "jack-rabbit"
starts or full-throttle shifts and maintain a steady cruising speed. Do
not race between stop lights. Try to
adjust your speed to the traffic so
you do not have to change speeds
unnecessarily. Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid un‐
necessary braking. This also reduces
brake wear.
• Drive at a moderate speed. The fast‐ er you drive, the more fuel your vehi‐cle uses. Driving at a moderate
speed, especially on the highway, is
one of the most effective ways to re‐
duce fuel consumption. • Do not "ride" the brake or clutch ped‐
al. This can increase fuel consumption
and also increase wear on these com‐
ponents. In addition, driving with your
foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may lead to more serious consequences.
• Take care of your tires. Keep them inflated to the recommended pres‐
sure. Incorrect inflation, either too
much or too little, results in unneces‐
sary tire wear. Check the tire pres‐ sures at least once a month.
• Be sure that the wheels are aligned correctly. Improper alignment can re‐
sult from hitting curbs or driving too
fast over irregular surfaces. Poor alignment causes faster tire wear
and may also result in other prob‐
lems as well as greater fuel con‐
sumption.
• Keep your vehicle in good condition. For better fuel economy and reducedmaintenance costs, maintain your ve‐
hicle in accordance with the mainte‐
nance schedule in Chapter 9, Mainte‐
nance. If you drive your vehicle in se‐
vere conditions, more frequent main‐ tenance is required (see Chapter 9,
Maintenance for details). • Keep your vehicle clean. For maxi‐
mum service, your vehicle should be
kept clean and free of corrosive ma‐ terials. It is especially important that
mud, dirt, ice, etc. not be allowed to
accumulate on the underside of the
vehicle. This extra weight can result
in increased fuel consumption and al‐ so contribute to corrosion.
• Travel lightly. Do not carry unneces‐ sary weight in your vehicle. Weight
reduces fuel economy.
• Do not let the engine idle longer than necessary. If you are waiting (and notin traffic), turn off your engine and
restart only when you're ready to go.
• Remember, your vehicle does not re‐ quire 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 warmup period.
• Do not "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking.
If this happens, shift to a lower gear. Over-revving is racing the engine be‐
yond its safe limit. This can be avoi‐
ded by shifting at the recommended
speeds.

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.
