Always come to a complete stop before
shifting into P (Park). This position locks
the transaxle and prevents the front
wheels from rotating.
WARNING- Automatic
transaxle
Always check the surrounding
areas near your vehicle for peo-
ple, especially children, before
shifting a shift lever into D (Drive)
or R (Reverse).
Before leaving the driver’s seat, always make sure the shift lever
is in the P (Park) position; then
set the parking brake fully and
shut the engine off. Unexpected
and sudden vehicle movement
can occur if these precautions
are not followed in the order iden-
tified.
CAUTION
To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on.
When stopped on an upgrade, do not hold the vehicle with enginepower. Use the service brake orthe parking brake.
Do not shift from N (Neutral) or P (Park) into D (Drive), or R(Reverse) when the engine isabove idle speed.

Driving your vehicle
Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
(Continued)
When descending a long or steephill, shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
Wet brakes may impair the vehi- cle’s ability to sefely slow down;
the vehicle may also pull to one
side when the brakes are applied.
Applying the brakes lightly will
indicate whether they have been
affected in this way. Always test
your brakes in this fashion after
driving through deep water. To
dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
Always, confirm the position of the brake and accelerator pedal
before driving. If you don't check
the position of the accelerator
and brake pedal before driving,
you may depress the accelerator
instead of the brake pedal. It may
cause a serious accident.
WARNING- Parking brake
Applying the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.
WARNING- Brakes
Do not drive with your foot rest-ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.

If the parking brake does not release or
does not release all the way, have the
system checked by an authorized Kia
dealer.
Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will illuminate 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 necessary.
If at all possible, stop driving the vehicle
immediately. If that is not possible, use
extreme caution while operating the vehi-
cle and only continue to drive the vehicle
until you can reach a safe location or
repair shop.Anti-lock brake system (ABS)
(if equipped)
WARNING
ABS (or ESC) will not prevent acci-
dents due to improper or danger-
ous 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 braking distance for vehicles
equipped with an anti-lock braking
system (Electronic Stability Control
System) may be longer than for
those without it in the following
road conditions.
During these conditions the vehicle
should be driven at reduced
speeds:
Rough, gravel or snow-coveredroads.
On roads where the road surface is pitted or has different surface
height.

WARNING
To prevent unintentional move-ment when stopped and leaving
the vehicle, do not use the
gearshift lever in place of the
parking brake. Set the parking
brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transaxle
equipped vehicles and in P (Park)
for automatic transaxle equipped
vehicles.
Never allow anyone who is unfa- miliar with the vehicle to touch
the parking brake. If the parking
brake is released unintentionally,
serious injury may occur.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

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 malfunctioned.
• 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 stabilize 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 management
system to stabilize the vehicle.
CAUTION
When you drive on a road with
poor traction, such as an icy road,and operated your brakes contin-uously, the ABS will be activecontinuously and the ABS warn- ing light may illuminate. Pull yourvehicle over to a safe place andstop the engine.
Restart the engine. If the ABS warning light is off, then yourABS system is normal.Otherwise, you may have a prob-lem with the ABS. Contact anauthorized Kia dealer as soon aspossible.

Good braking practices
Check to be sure the parking brake is
not engaged and that the parking
brake indicator light is out before driv-
ing 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 extremely haz-
ardous. 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.
Don't "ride" the brake pedal. Resting your foot on the brake pedal while driv-
ing can be dangerous because the
brakes might overheat and lose their
effectiveness. It also increases the
wear of the brake components. If a tire goes flat while you are driving,
apply the brakes gently and keep the
vehicle pointed straight ahead while
you slow down. When you are moving
slowly enough for it to be safe to do so,
pull off the road and stop in a safe
place.
If your vehicle is equipped with an automatic transaxle, don't let your vehi-
cle creep forward. To avoid creeping
forward, keep your foot firmly on the
brake pedal when the vehicle is
stopped.
Be cautious when parking on a hill. Firmly engage the parking brake and
place the shift lever in P (automatic
transaxle) or in first or reverse gear
(manual transaxle). If your vehicle is
facing downhill, turn the front wheels
into the curb to help keep the vehicle
from rolling. If your vehicle is facing
uphill, turn the front wheels away from
the curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to keep
the vehicle from rolling, block the
wheels.
WARNING
Whenever you leave or park yourvehicle, always set the parking
brake as far as possible and fully
engage the vehicle's transaxle
into the P (Park) position. If the
parking brake is not fully
engaged, the vehicle may move
inadvertently and injure yourself
and others.
All vehicles should always have the parking brake fully engaged
when parking to avoid inadver-
tent movement of the vehicle
which can injure occupants or
pedestrians.

Driving your vehicle
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 gal-
lon (liter) 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:
Drive smoothly. Accelerate at a moder-ate rate. Don't make "jack-rabbit" starts
or full-throttle shifts and maintain a
steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to the traffic so you don't have to
change speeds unnecessarily. Avoid
heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid unnec-
essary 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 con-
sumption. Don't "ride" the brake pedal. This can
increase fuel consumption and also
increase wear on these components.
In addition, driving with your foot rest-
ing on the brake pedal may cause the
brakes to overheat, which reduces
their effectiveness and may lead to
more serious consequences.
Take care of your tires. Keep them inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
Be sure that the wheels are aligned correctly. Improper alignment can
result from hitting curbs or driving too
fast over irregular surfaces. Poor align-
ment causes faster tire wear and may
also result in other problems as well as
greater fuel consumption. Keep your vehicle in good condition.
For better fuel economy and reduced
maintenance costs, maintain your vehi-
cle in accordance with the mainte-
nance schedule in section 7. If you
drive your vehicle in severe conditions,
more frequent maintenance is required
(see section 7 for details).
Keep your vehicle clean. For maximum 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 unnecessary 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.
