Driving your vehicle
The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.

Driving tips4 5BEFORE DRIVING Before entering vehicle: Be sure that all windows, outside mir-
ror(s), and outside lights are clean.
Check the condition of the tires.
Check under the vehicle for any sign of
leaks.
Be sure there are no obstacles behind
you if you intend to back up.Necessary inspections Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in
Section 7, Maintenance.
Before starting Close and lock all doors.
Position the seat so that all controls are
easily reached.
Adjust the inside and outside rearview
mirrors.
Be sure that all lights work.
Check all gauges.
Check the operation of warning lights
when the ignition switch is turned to

iar with your vehicle and its equipment.
WARNING
- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgement. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or take
drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.

Driving tips
SUGGESTIONS FOR ECONOMICAL OPERATIONYour 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 possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
Avoid lengthy warm-up idling. Once the
engine is running smoothly, begin driv-
ing. Remember, engine warm-up may
take a little longer on cold days.
Save fuel by accelerating slowly after
stopping.
Keep the engine in tune and follow the
recommended periodic maintenance
schedule. This will increase the life of
all parts and lower your operating
costs.
Do not use the air conditioner unnec-
essarily.
Slow down when driving on rough
roads.
For longer tire life and better fuel econ-
omy, always keep the tires inflated to
the recommended pressures. Maintain a safe distance from other
vehicles to avoid sudden stops. This
will reduce wear on brake linings and
pads. Driving in such a way will also
save fuel because extra fuel is required
to accelerate back to driving speed.
Do not carry unnecessary weight in the
vehicle.
Do not rest your foot on the brake
pedal while driving. This can cause
needless wear, possible damage to the
brakes, and poor fuel economy.
Improper wheel alignment results in
faster tire wear and lower fuel econo-
my.
Open 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 con-
dition is important both for economy and
safety. Therefore, have an authorized Kia
dealer perform scheduled inspections
and maintenance.
WARNING
- Engine off dur-
ing 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 run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect.

Driving tips6 5SPECIAL DRIVING CONDITIONSHazardous driving conditions When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
Drive cautiously and allow extra dis-
tance for braking.
Avoid sudden movements in 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. If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
Use sand, rock salt, tire chains, or
other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.
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 1 (First) and
R (Reverse) in vehicles equipped with a
manual transaxle or R (Reverse) and any
forward gear in vehicles equipped with
an automatic transaxle. 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
possible damage to the transaxle.✽ ✽
NOTICEProlonged rocking may cause engine
over-heating, transaxle damage or fail-
ure, and tire damage.
CAUTION
- ABS
Do not pump the brake pedal on a
vehicle equipped with ABS.
WARNING
- Downshifting
Downshifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.
WARNING
- Spinning tires
Do not spin the wheels, especially
at speeds more than 56 km/h (35
mph). Spinning the wheels at high
speeds when the vehicle is station-
ary could cause a tire to overheat,
explode and injure bystanders.
