When the hands-off warning
lasts for a certain period of
time
If the driver still does not have their
hands on the steering wheel after the
message "Keep hands on steering
wheel", HDA will be canceled.
However, if Smart Cruise Control is
reactivated manually by the driver,
Highway Driving Assist will reacti-
vate.
To activate Smart Cruise control
refer to "Smart Cruise Control
(SCC)" in this chapter.HDA will not be in the ENABLED
state and/or the steering wheel will
not be assisted when:
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on,
the steering wheel might be con-
trolled.
The vehicle is not driven in the mid-
dle of the lane when the function is
turned on or right after changing a
lane.
ESC (Electronic Stability Control or
VSM (Vehicle Stability
Management) is activated.
The vehicle is driven on a sharp
curve.
Vehicle speed is over 95 mph (153
km/h)
The vehicle makes sharp lane
changes.
CAUTION
The hands-off warning may be
delayed depending on road
conditions. Always keep your
hands on the steering wheel

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 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 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.
ECONOMICAL OPERATION

5183
Driving your vehicle
Remember, your vehicle does not
require 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 warm-
up period.
Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in a
very high gear resulting in engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speed. Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
Opening windows at high speeds
can reduce fuel economy.
Fuel economy is less in crosswinds
and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.
Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, have an
authorized Kia dealer perform
scheduled inspections and mainte-
nance.
WARNING - Engine off
during motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running.
In addition, turning off the
engine start/stop button while
driving could engage the steer-
ing wheel lock, resulting in loss
of vehicle steering. Keep the
engine on and downshift to an
appropriate gear for an engine
braking effect.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
Drive cautiously and allow extra
distance for braking.
Avoid sudden braking or steering.
When braking with non-ABS
brakes pump the brake pedal with
a light up-and-down motion until
the vehicle is stopped.
Do not pump the brake pedal on a
vehicle equipped with ABS. If stalled in snow, mud, or sand,
use the second gear. Accelerate
slowly to avoid spinning the drive
wheels.
Use sand, rock salt, or other non-
slip material under the drive
wheels to provide traction when
stalled in ice, snow, or mud.
Reducing the risk of a rollover
This multi-purpose passenger vehi-
cle is defined as a Sports Utility
Vehicle (SUV). Utility vehicles have a
significantly higher rollover rate than
other types of vehicles. SUV's have
higher ground clearance and a nar-
rower track to make them capable of
performing in a wide variety of off-
road applications. Specific design
characteristics give them a higher
center of gravity than ordinary vehi-
cles. An advantage of the higher
ground clearance is a better view of
the road, which allows you to antici-
pate problems. They are not
designed for cornering at the same
speeds as conventional passenger
vehicles, any more than low-slung
sports vehicles are designed to per-
form satisfactorily in off-road condi-
tions. Due to this risk, driver and pas-
sengers are strongly recommended
to buckle their seat belts. In a rollover
crash, an unbelted person is signifi-
cantly more likely to die than a per-
son wearing a seat belt. There are
steps that a driver can make to
reduce the risk of a rollover.
SPECIAL DRIVING CONDITIONS
WARNING- Downshifting
Do not downshift with a dual
clutch transmission while driv-
ing on slippery surfaces. The
sudden change in tire speed
could cause the tires to skid
and result in an accident.

5185
Driving your vehicle
If at all possible, avoid sharp turns or
abrupt maneuvers, do not load your
roof rack with heavy cargo, and
never modify your vehicle in any way.
WARNING
Your vehicle is equipped with
tires designed to provide safe
ride and handling capability. Do
not use a size and type of tire
and wheel that is different from
the one that is originally
installed on your vehicle. It can
affect the safety and perform-
ance of your vehicle, which
could lead to steering failure or
rollover and serious injury.
When replacing the tires, be
sure to equip all four tires with
the tire and wheel of the same
size, type, tread, brand and
load-carrying capacity. If you
nevertheless decide to equip
your vehicle with any tire/wheel
combination not recommended
by Kia for off road driving, you
should not use these tires for
highway driving.
WARNING - Rollover
As with other Sports Utility
Vehicles (SUV), failure to oper-
ate this vehicle correctly may
result in loss of control, an acci-
dent or vehicle rollover.
Utility vehicles have a signifi-
cantly higher rollover rate
than other types of vehicles.
Specific design characteris-
tics (higher ground clearance,
narrower track, etc.) give this
vehicle a higher center of
gravity than ordinary vehicles.
A SUV is not designed for cor-
nering at the same speeds as
conventional vehicles.
Avoid sharp turns or abrupt
maneuvers.
(Continued)
(Continued)
In a rollover crash, an unbelt-
ed person is significantly
more likely to die than a per-
son wearing a seat belt. Make
sure everyone in the vehicle is
properly buckled up.

Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
front wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with a dual clutch transmission. Do
not race the engine, and spin the
wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transaxle.
The ESC system should be turned
OFF prior to rocking the vehicle.
Smooth cornering
Avoid braking or gear changing in
corners, especially when roads are
wet. Ideally, corners should always
be taken under gentle acceleration. If
you follow these suggestions, tire
wear will be held to a minimum.CAUTION- Vehicle rocking
Prolonged rocking may cause
engine overheating, transaxle
damage or failure, and tire dam-
age.
CAUTION- Spinning tires
Do not spin the wheels, espe-
cially at speeds more than 35
mph (56 km/h). Spinning the
wheels at high speeds when the
vehicle is stationary could
cause a tire to overheat which
could result in tire damage that
may injure bystanders.
WARNING- Sudden
Vehicle Movement
Do not attempt to rock the vehi-
cle if people or objects are near-
by. The vehicle may suddenly
move forward or backwards as it
becomes unstuck.

Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
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 engine oil
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
result in overheating of the engine.
WARNING- Under/over
inflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
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 8.

5189
Driving your vehicle
Severe weather conditions in the
winter result in greater wear and
other problems. To minimize the
problems of winter driving, you
should follow these suggestions: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 neces-
sary 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 acceleration, sudden brake
applications, and sharp turns are
potentially very hazardous practices.
During deceleration, use engine
braking to the fullest extent. Sudden
brake applications on snowy or icy
roads may cause skids to occur. You
need to keep sufficient distance
between the vehicle in operation in
front of 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.
Tire chains are not legal in all states.
Check state 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 provid-
ed by snow tires on dry roads may
not be as high as your vehicle's orig-
inal equipment 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 munic-
ipal regulations for possible restric-
tions against their use.
WINTER DRIVING

Driving your vehicle

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 vehicles 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
0.47 in (12 mm). Damage to your
vehicle caused by improper snow
chain use is not covered by your
vehicle manufacturers warranty.When using tire chains, install tire
chains only on the front tires.
The snow chain connecting hooks
may be damaged from contacting
vehicle components causing the
snow chains to come loose from the
tire. Make sure the snow chains are
SAE class “S” certified.
Always check chain installation for
proper mounting after driving
approximately 0.3 to 0.6 miles (0.5 to
1 km) to ensure safe mounting.
Retighten or remount the chains if
they are loose.
If your vehicle has 18 inch tires, do
not use tire chains.
They can damage your vehicle
(wheel, suspension and body).Chain installation
When installing chains, follow the
manufacturer'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 begin driving
on cleared roads.
When mounting snow chains, park
the vehicle on level ground away
from traffic. Turn on the vehicle
Hazard Warning flashers and place a
triangular emergency warning device
behind the vehicle if available.
Always place the vehicle in P (Park),
apply the parking brake and turn off
the engine before installing snow
chains.
CAUTION- Snow chains
Make sure the snow chains are
the correct size and type for
your tires. Incorrect snow
chains can cause damage to the
vehicle body and suspension
and may not be covered by your
vehicle manufacturer warranty.
