Air bag warning light
This warning light will illuminate for
approximately 6 seconds each time you
turn the ignition switch to the ON posi-
tion.
This light also comes on when the
Supplement Restraint System (SRS) is
not working properly. If the air bag warn-
ing light does not come on, or continu-
ously remains on after operating for
about 6 seconds when you turned the
ignition switch to the ON position or start-
ed the engine, or if it comes on while
driving, have the SRS inspected by an
authorized KIA dealer.
Anti-lock brake system(ABS) warning light (if equipped)
This warning light illuminates if the igni-
tion switch is turned ON and goes off in
approximately 3 seconds if the system is
operating normally.
If the ABS warning light remains on,
comes on while driving, or does not
come on when the ignition switch is
turned to the ON position, this indicates
that the ABS may have malfunctioned.
If this occurs, have your vehicle checked
by an authorized KIA dealer as soon as
possible. The normal braking system will
still be operational, but without the assis-
tance of the anti-lock brake system. Electronic brake
force distribution
(EBD) system

If these two warning lights illuminate at
the same time while driving, your vehi-
cle’s ABS and EBD system may have
malfunctioned.
In this case, your ABS and regular brake
system may not work normally. Have the
vehicle checked by an authorized KIA
dealer as soon as possible.
WARNING
If both ABS and Brake warning
lights are on and stay on, your vehi-
cle’s brake system will not work
normally during sudden braking. In
this case, avoid high speed driving
and abrupt braking. Have your vehi-
cle checked by an authorized KIA
dealer as soon as possible.

Low brake fluid level warning
If the warning light remains on, it may
indicate that the brake fluid level in the
reservoir is low.
If the warning light remains on:
1. Drive carefully to the nearest safe
location and stop your vehicle.
2. With the engine stopped, check the brake fluid level immediately and add
fluid as required. Then check all brake
components for fluid leaks.
3. Do not drive the vehicle if leaks are found, the warning light remains on or
the brakes do not operate properly.
Have the vehicle towed to any author-
ized KIA dealer for a brake system
inspection and necessary repairs.
Your vehicle is equipped with dual-diago-
nal braking systems. This means you still
have braking on two wheels even if one
of the dual systems should fail. With only
one of the dual systems working, more
than normal pedal travel and greater
pedal pressure are required to stop the
vehicle. Also, the vehicle will not stop in
as short a distance with only a portion of
the brake system working. If the brakes
fail while you are driving, shift to a lower
gear for additional engine braking and
stop the vehicle as soon as it is safe to do
so. To check bulb operation, check whether
the parking brake and brake fluid warning
light illuminates when the ignition switch
is in the ON position.Front fog light indicator
(if equipped)
This indicator comes on when the front
fog lights are ON.
Shift pattern indicator (if equipped)
The indicator displays which automatic
transaxle shift position is selected.
WARNING
Driving the vehicle with a warning
light on is dangerous. If the brake
warning light remains on, have the
brakes checked and repaired imme-
diately by an authorized KIA dealer.

1. Moisture is frozen to the sensor. (It will
operate normally when the moisture
has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-
ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.

height or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.

Driving your vehicle
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
the ON position.
Release the parking brake and make sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.
BEFORE DRIVING
WARNING
All passengers must be properly
belted whenever the vehicle is mov-
ing. Refer to “Seat belts” in section
3 for more information on their
proper use.
WARNING
Always check the surrounding areas
near your vehicle for people, espe-
cially children, before putting a vehi-
cle into D (Drive) or R (Reverse).
WARNING
Driving while distracted can result
in a loss of vehicle control, that
may lead to an accident, severe
personal injury, and death. The dri-
ver’s primary responsibility is in
the safe and legal operation of a
vehicle, and use of any handheld
devices, other equipment, or vehi-
cle systems which take the driver’s
eyes, attention and focus away
from the safe operation of a vehicle
or which are not permissible by law
should never be used during oper-
ation of the vehicle.
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 dan-
gerous 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.

is engaged in 1st gear for the
manual transaxle or P (Park) for
the automatic transaxle, set the
parking brake fully and shut the
engine off. Unexpected and sud-
den vehicle movement may occur
if these precautions are not
taken.

through the steering wheel while
the vehicle is in motion. The pres-
ence of your hand or arm in this
area could cause a loss of vehicle
control, an accident and serious
bodily injury or death.
