the engine or exhaust system
and cause a fire.
WARNING - Loose object

den stop or turn the steering
wheel rapidly, loose objects
may drop on the floor and it
could interfere with the opera-
tion of the foot pedals, possibly
causing an accident.WARNING - Check sur- rounding

ple, especially children, before
putting a vehicle into D (Drive)
or R (Reverse).

Drinking and driving is danger-
ous. Even a small amount of
alcohol will affect your reflexes,
perceptions and judgment.
Driving while under the influ-
ence of drugs including certain
prescription drugs is as danger-
ous as or more dangerous than
driving drunk.

Even if the smart key is in the vehi- cle, but is far away from you, the
engine may not start.
When the ENGINE START/STOP button is in the ACC position or

Check the brake warning light by
turning the ignition switch ON (do not
start the engine). This light will illumi-
nate when the parking brake is
applied with the ignition switch in the
START or ON position.
Before driving, be sure the parking
brake is fully released and the brake
warning light is off.
If the brake warning light remains on
after the parking brake is released
while the engine is running, there
may be a malfunction in the brake
system. Immediate attention is nec-
essary. If at all possible, stop driving the
vehicle immediately. If that is not pos-
sible, use extreme caution while
operating the vehicle and only con-
tinue to drive the vehicle until you
can reach a safe location or repair
shop.
Anti-lock brake system (ABS)
ABS (or ESC) will not prevent acci-
dents due to improper or dangerous
driving maneuvers. Even though
vehicle control is improved during
emergency braking, always maintain
a safe distance between you and
objects ahead. Vehicle speeds
should always be reduced during
extreme road conditions.
The vehicle should be driven at
reduced speeds in the following cir-
cumstances:
When driving on rough, gravel or
snow-covered roads
When driving on roads where the road surface is pitted or has differ-
ent surface heights.
Driving in these conditions increases
the stopping distance for your vehi-
cle.

When you drive on a road with
poor traction, such as an icy road,
and operated your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your vehi-
cle over to a safe place and stop
the engine.
Restart the engine. If the ABS warning light is off, then your ABS
is normal. Otherwise, you may
have a problem with the ABS.
Contact an authorized Kia dealer
as soon as possible.✽ ✽ NOTICE
When you jump start your vehicle
because of a drained battery, the
engine may not run as smoothly and
the ABS warning light may turn on
at the same time. This happens
because of the low battery voltage. It
does not mean your ABS has mal-
functioned.
• Do not pump your brakes!
• Have the battery recharged before
driving the vehicle.
Electronic stability control
(ESC)
The Electronic Stability control
(ESC) system is designed to stabi-
lize the vehicle during cornering
maneuvers. ESC checks where you
are steering and where the vehicle is
actually going. ESC applies the
brakes on individual wheels and
intervenes with the engine manage-
ment system to stabilize the vehicle.
Electronic stability control (ESC) will
not prevent accidents. Excessive
speed in turns, abrupt maneuvers
and hydroplaning on wet surfaces
can still result in serious accidents.

WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.

The Vehicle Stability Management
system is not a substitute for safe
driving practices but a supplemen-
tary function only. It is the respon-
sibility of the driver to always check
the speed and the distance to the
vehicle ahead. Always hold the
steering wheel firmly while driving.
Your vehicle is designed to react according to the driver’s intention,
even with installed VSM. Always
follow all the normal precautions
for driving at safe speeds for the
conditions – including driving in
inclement weather and on a slip-
pery road.Good braking practices
Check to be sure the parking brakeis not engaged and that the park-
ing brake indicator light is out
before driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one
side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at
all times. If the braking action does
not return to normal, stop as soon
as it is safe to do so and call an
authorized Kia dealer for assis-
tance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed.
WARNING- Tire/Wheel
size
When replacing tires and
wheels, make sure they are the
same size as the original tires
and wheels installed. Driving
with varying tire or wheel sizes
may diminish any supplemental
safety benefits of the VSM sys-
tem.
WARNING
For maximum protection,
always wear your seat belt. No
system, no matter how
advanced, can compensate for
all driver error and/or driving
conditions. Always drive
responsibly.
