For smooth operation, depress the
brake pedal and the lock release but-ton when shifting from N (Neutral) toa forward or reverse gear.
When stopped on an incline, do not
hold the vehicle with the engine
power. Use the service brake or the
parking brake.
Transaxle ranges
The indicator in the instrument clus-
ter displays the shift lever position
when the engine start/stop button is
in the ON position.
P (Park)
Always come to a complete stop
before shifting into P (Park). This
position locks the transaxle and pre-
vents the drive wheels from rotating.
Shifting into P (Park) while the vehi-
cle is in motion will cause the drive
wheels to lock which will cause you
to lose control of the vehicle.
To shift from P (Park), you must
depress firmly on the brake pedal
and make sure your foot is off the
accelerator pedal.
If you have done all of the above
and still cannot shift the lever out of
P (Park), see "Shift-lock override" in
this chapter.
The shift lever must be in P (Park)
before turning the hybrid system off.
WARNING- Leaving
Vehicle
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. Do not use
the P position in place of the
parking brake. Always make
sure the shift lever is locked in
the P position and set the park-
ing brake fully. Unexpected and
sudden vehicle movement can
occur if these precautions are
not followed.
CAUTION- Transaxle
To avoid damage to your transaxle, do not accelerate theengine in R (Reverse) or any for-ward gear position with thebrakes on. The transaxle may bedamaged if you shift into P(Park) while the vehicle is inmotion.

Driving your vehicle
R (Reverse)
Use this position to drive the vehicle
backward.N (Neutral)
The wheels and transaxle are not
engaged. The vehicle will roll freely
even on the slightest incline unless
the parking brake or service brakes
are applied.
- Parking in N (Neutral) gear
Follow below steps when parking
and you want the vehicle to move
when pushed.
1. After parking your vehicle, step on
the brake pedal and move the
transaxle shift lever to P (Park)
with the ignition button in ON or
while the engine is running.
2. If the parking brake is applied, unlock the parking brake.
- For EPB (Electronic Parking Brake) equipped vehicles, push
the brake pedal with the ignition
button in [ON] or while the
engine is running to disengage
the parking brake. If AUTO
HOLD function is used while
driving (If AUTO HOLD indicator
is on in the cluster), press AUTO
HOLD switch and AUTO HOLD
function should be turn off. 3. While depressing the brake pedal,
turn the ignition button OFF.
- For smart key equipped vehicles, the ignition switch can be moved
to OFF only when the shift lever
is in P (Park).
4. Change the gear shift lever to N (Neutral) while pressing the brake
pedal and pushing [SHIFT LOCK
RELEASE] button or inserting,
pressing down a tool (e.g. flathead
screw-driver) into the [SHIFT
LOCK RELEASE] access hole at
the same time. Then, the vehicle
will move when external force is
applied.
CAUTION- Shifting
Always come to a complete stopbefore shifting into or out of R(Reverse); you may damage thetransaxle if you shift into R(Reverse) while the vehicle is inmotion, except when “Rockingthe vehicle” explained in thischapter.

5. Move the shift lever.
6. Remove the tool from the shiftlockoverride access hole then install
the cap.
7. Have your vehicle inspected by an authorized Kia dealer.
If your vehicle is equipped with
ENGINE START/STOP button, the
button will not change to the OFF
position unless the shift lever is in the
P (Park) position.Good driving practices
Never move the gear shift lever from P (Park) to any other position with
the accelerator pedal depressed.
Never move the gear shift lever into P (Park) when the vehicle is in
motion.
Slow down before shifting to a lower gear. Otherwise, the lower
gear may not be engaged.
Always use the parking brake. Do not depend on placing the
transaxle in P (Park) to keep the
vehicle from moving.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator pedal.
✽ ✽ NOTICE- Kickdown
Mechanism
Use the kickdown mechanism for
maximum acceleration. Depress the
accelerator pedal beyond the pres-
sure point. The automatic transaxle
will shift to a lower gear depending
on the engine speed.
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
service brakes.

619
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- Parkingbrake
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.

689
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 gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at amoderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos- sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary 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 consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 8. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 8 for details).
Keep your vehicle clean. For maxi- mum 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 unneces- sary 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.
ECONOMICAL OPERATION

697
Driving your vehicle
The use of chains may adverselyaffect vehicle handling.
Do not exceed 20 mph (30 km/h) or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
Drive carefully and avoid bumps, holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
Avoid sharp turns or locked-wheel braking.Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.CAUTION- Snow chains
Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
✽
✽NOTICE
If the TPMS, Low Tire Pressure
indicator does not illuminate for 3
seconds when the ignition switch is
turned to the ON position or engine
is running, or if they remain illumi-
nated after coming on for approxi-
mately 3 seconds, take your vehicle
to your nearest authorized Kia deal-
er and have the system checked.
Low tire pressure
telltale
Low tire pressure position tell-
tale
When the tire pressure monitoring
system warning indicators are illumi-
nated, one or more of your tires is
significantly under-inflated.
If the telltale illuminates, immediately
reduce your speed, avoid hard cor-
nering and anticipate increased stop-
ping distances. You should stop and
check your tires as soon as possible. Inflate the tires to the proper pres-
sure as indicated on the vehicle’s
placard or tire inflation pressure label
located on the driver’s side center pil-
lar outer panel. If you cannot reach a
service station or if the tire cannot
hold the newly added air, replace the
low pressure tire with the spare tire.
Then the TPMS malfunction indicator
and the Low Tire Pressure telltale
may turn on and illuminate after
restarting and about 20 minutes of
continuous driving before you have
the low pressure tire repaired and
replaced on the vehicle.
In winter or cold weather, the low tire
pressure telltale may be illuminated if
the tire pressure was adjusted to the
recommended tire inflation pressure
in warm weather. It does not mean
your TPMS is malfunctioning
because the decreased temperature
leads to a proportional lowering of
tire pressure.
