Driving your vehicle
5. Move the shift lever.
6. Remove the tool from the shiftlockoverride access hole then install
the cap.
7. Have the system inspected by a professional workshop. Kia recom-
mends to visit an authorized Kia
dealer/service partner. Ignition key interlock system
(if equipped)
The ignition key cannot be removed
unless the shift lever is in the P
(Park) position.Good driving practices
Never move the shift lever from P
(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in motion.
Be sure the car is completely stopped before you attempt to shift
into R (Reverse) or D (Drive).
Never take the car out of gear and coast down a hill. This may be
extremely hazardous. Always leave
the car in gear when moving.
Do not "ride" the brakes. This can cause them to overheat and mal-
function. Instead, when you are
driving down a long hill, slow down
and shift to a lower gear. When you
do this, engine braking will help
slow the car.
Slow down before shifting to a lower gear. Otherwise, the lower
gear may not be engaged.
WARNING
When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator pedal for a long period of
time. The engine or exhaust
system may overheat and start
a fire. The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components. Do not
stop or park over flammable
materials, such as dry grass,
paper or leave. They may ignite
and cause a fire.

Always use the parking brake. Do
not depend on placing the
transaxle in P (Park) to keep the
car from moving.
Exercise extreme caution when driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
the vehicle to go out of control.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator pedal.
WARNING
Always buckle-up! In a colli-sion, an unbelted occupant is
significantly more likely to be
seriously injured or killed than
a properly belted occupant.
Avoid high speeds when cor- nering or turning.
Do not make quick steering wheel movements, such as
sharp lane changes or fast,
sharp turns.
The risk of rollover is greatly increased if you lose control
of your vehicle at highway
speeds.
Loss of control often occurs if two or more wheels drop off the
roadway and the driver over-
steers to reenter the roadway.
In the event your vehicle leaves the roadway, do not
steer sharply. Instead, slow
down before pulling back into
the travel lanes.
Never exceed posted speed limits.
WARNING
If your vehicle becomes stuck in
snow, mud, sand, etc., then you
may attempt to rock the vehicle
free by moving it forward and
backward. Do not attempt this
procedure if people or objects
are anywhere near the vehicle.
During the rocking operation the
vehicle may suddenly move for-
ward or backward as it becomes
unstuck, causing injury or dam-
age to nearby people or objects.

Driving your vehicle
Moving up a steep grade from astanding start
To move up a steep grade from a
standing start, depress the brake
pedal, shift the shift lever to D
(Drive). Select the appropriate gear
depending on load weight and steep-
ness of the grade, and release the
parking brake. Depress the accelera-
tor gradually while releasing the
brake pedal.

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 normally would. The
stopping distance, however, 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
necessary to maintain steering con-
trol on slippery surfaces. Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle 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 fash-
ion after driving through deep water.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
BRAKE SYSTEM
WARNING- Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
CAUTION- Brake Pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

Driving your vehicle
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 dis-
tance, however, will be much greater
than normal.
Disc brakes wear indicator
When your brake pads are worn and
new pads are required, you will hear
a high-pitched warning sound from
your front brakes or rear brakes. You
may hear this sound come and go or
it may occur whenever you depress
the brake pedal.
Please remember that some driving
conditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
Always replace the front or rear
brake pads as pairs.
WARNING- Parking
brake
Avoid applying the parking
brake to stop the vehicle while it
is moving except in an emer-
gency situation. 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
applying the brake.
WARNING- Brake wear
Do not ignore high pitched wear
sounds from your brakes. If you
ignore this audible warning, you
will eventually lose braking per-
formance, which could lead to a
serious accident.
CAUTION- Replace brake pads
Do not continue to drive withworn brake pads. Continuing todrive with worn brake pads candamage the braking system andresult in costly brake repairs.
