Driving your vehicle
Driving with varying tire or wheel
sizes may cause the ESC system to
malfunction. When replacing tires,
make sure they are the same size as
your original tires.ESC OFF usage
When driving
It’s a good idea to keep the ESCturned on for daily driving whenev-
er possible.
To turn ESC off while driving, press the ESC OFF button while driving
on a flat road surface.
Never press the ESC OFF button
while ESC is operating (ESC indica-
tor light blinks).
If ESC is turned off while ESC is
operating, the vehicle may slip out of
control.
Hill-start assist control (HAC)
Hill start Assist Control is a comfort
function. The main intent is to pre-
vent the vehicle from rolling back-
wards while driving uphill on an
inclined surface. HAC holds the brak-
ing pressure builtup by driver during
stopping procedure for 2 seconds
after releasing brake pedal.
During the pressure-hold period, the
driver has enough time to press the
accelerator pedal to drive off.
The braking pressure is reduced as
soon as the system detects the dri-
ver’s intention to drive off.
WARNING - Operating ESC
Never press the ESC OFF but-
ton while ESC is operating.
If the ESC is turned off while
ESC is operating, the vehicle
may go out of control.
WARNING - Electronic
stability control
Drive carefully even though
your vehicle has Electronic
Stability Control. It can only
assist you in maintaining con-
trol under certain circum-
stances.
WARNING - Activating HAC
Drivers should pay close atten-
tion when activating the HAC.
The vehicle may roll backward
causing an accident due to
insufficient brake hold pres-
sure.

Driver's Attention
The driver must be cautious in the
below situations for the system may
not assist the driver and may not
work properly.
- Curved roads, tollgates, etc.
- The surrounding of the sensor is
polluted with rain, snow, mud, etc
- The rear bumper near the sensor is covered or hidden with a foreign
matter such as a sticker, bumper
guard, bicycle stand etc.
- The rear bumper is damaged or the sensor is out of place.
- The height of the vehicle shows much change such as when the
trunk is loaded with heavy objects,
abnormal tire pressure etc.
- Due to bad weather such as heavy rain or snow.
- A fixed object is near such as a guardrail, etc.
- A lot of amount of metal sub- stances are near the vehicles such
as a construction area. - A big vehicle is near such as a bus
or truck.
- A motorcycle or bicycle is near.
- A flat trailer like vehicle is near.
- If the vehicle has started at the same time as the vehicle next to it
and has accelerated.
- When the other vehicle passes by very fast.
- When changing lanes.
- When going down or up a steep road where the height of the lane is
different.
- When the other vehicle drives at the rear very nearby or drives very
close.
- When a trailer or carrier is installed.
- When the temperature of rear bumper is high.
- When the sensors are covered by the vehicle, wall and pillar of park-
ing lot.
- When your vehicle moves back, if the detected vehicle also moves
back.
- If there is small things like shopping cart and baby carriage.
CAUTION
The system may not work properly if the bumper hasbeen replaced or if a repairwork has been done near thesensor.
The detection area differs according to the roads width.If the road is narrow the sys-tem may detect other vehiclesin the next lane.
On the contrary, if the road is very wide the system may notdetect other vehicles.
The system may turn off due to strong electromagneticwaves.

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 miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. 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 con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 7 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. 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 also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.

Driving your vehicle
Driving off-road
Drive carefully off-road because your
vehicle may be damaged by rocks or
roots of trees. Become familiar with
the off-road conditions where you
are going to drive before you begin
driving.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engineoil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
overheat the engine.
WARNING - Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out
tires should be replaced as
soon as possible. For further
information and tread limits,
refer to "Tires and wheels" in
chapter 7.

What to do in an emergency
Then position the wrench as shown
in the drawing and tighten the wheel
nuts. Be sure the socket is seated
completely over the nut. Do not stand
on the wrench handle or use an
extension pipe over the wrench han-
dle.
Go around the wheel tightening
every nut following the numerical
sequence shown in the image until
they are tight. Then double-check
each nut for tightness. After changing
the wheels, have an authorized Kia
dealer tighten the wheel nuts to their
proper torque as soon as possible.Wheel nut tightening torque:
Steel wheel & aluminium alloy wheel:
9~11 kg.m (65~79 lb.ft)
If you have a tire gauge, remove the
valve cap and check the air pressure.
If the pressure is lower than recom-
mended, drive slowly to the nearest
service station and inflate to the cor-
rect pressure. If it is too high, adjust
it until it is correct. Always reinstall
the valve cap after checking or
adjusting the tire pressure. If the cap
is not replaced, air may leak from the
tire. If you lose a valve cap, buy
another and install it as soon as pos-
sible.
After you have changed wheels,
always secure the flat tire in its place
and return the jack and tools to their
proper storage locations.
Note that most lug nuts do not have
metric threads. Be sure to use
extreme care in checking for thread
style before installing aftermarket lug
nuts or wheels. If in doubt, consult an
authorized Kia dealer.
OTF060007
CAUTION - Reducing lug
nuts
Make certain during wheelremoval that the same nuts thatwere removed are reinstalled -or, if replaced, that nuts withmetric threads and the samechamfer configuration are used.Your vehicle has metric threadson the wheel studs and nuts.Installation of a non-metricthread nut on a metric stud willnot secure the wheel to the hubproperly and will damage thestud so that it must be replaced.

To prevent the jack, jack handle,
wheel lug nut wrench and spare tire
from rattling while the vehicle is in
motion, store them properly.
Important - use of compact spare
tire (if equipped)
Your vehicle is equipped with a com-
pact spare tire. This compact spare
tire takes up less space than a regu-
lar-size tire. This tire is smaller than a
conventional tire and is designed for
temporary use only.
The compact spare should be inflat-
ed to 420 kPa (60 psi).
✽ ✽NOTICE
Check the inflation pressure after
installing the spare tire. Adjust it to
the specified pressure, as necessary.
WARNING- Wheel studs
Do not drive your vehicle with
damaged wheel studs. If the
studs are damaged, they may
lose their ability to retain the
wheel. This could lead to the
loss of the wheel and a colli-
sion.
WARNING - Inadequate
spare tire pressure
Check the inflation pressures
as soon as possible after
installing the spare tire. Adjust
it to the specified pressure, if
necessary. Refer to “Tires and
wheels” in chapter 8.
WARNING
The compact spare tire is for
emergency use only. Do not
operate your vehicle on this
compact spare at speeds over
80 km/h (50 mph). The original
tire should be repaired or
replaced as soon as possible to
avoid failure of the spare possi-
bly leading to personal injury or
death.
CAUTION
You should drive carefully
when the compact spare is inuse. The compact spareshould be replaced by theproper conventional tire andrim at the first opportunity.
The operation of this vehicle is not recommended withmore than one compact sparetire in use at the same time.

What to do in an emergency
IF YOU HAVE A FLAT TIRE (WITH TIRE MOBILITY KIT, IF EQUIPPED)
For safe operation, carefully read
and follow the instructions in this
manual before use.
(1) Tire Mobility Kit bag
(2) Compressor
(3) Sealant bottle
The Tire Mobility Kit is a temporary
fix to the tire and the tire should be
inspected by an authorized Kia deal-
er as soon as possible.
Introduction
With the Tire Mobility Kit you stay
mobile even after experiencing a tire
puncture.
The system of compressor and seal-
ing compound effectively and com-
fortably seals most punctures in a
passenger car tire caused by nails
or similar objects and reinflates the
tire.
After you ensured that the tire is
properly sealed you can drive cau-
tiously on the tire (up to 200 km (120
miles )) at a max. speed of 80 km/h
(50 mph) in order to reach a service
station or tire dealer to have the tire
repaired or replaced.
OTF064023N
OYFH062021NWARNING -Tire wall
Do not use the Tire Mobility Kit
to repair punctures in the tire
walls. This can result in an acci-
dent due to tire failure.
WARNING - Temporary fix
Have your tire repaired as soon
as possible. The tire may loose
air pressure at any time after
inflating with the Tire Mobility
Kit.
CAUTION - One sealant for one tire
When two or more tires are flat,do not use the tire mobility kitbecause the supported onesealant of Tire Mobility Kit isonly used for one flat tire.
