tire pressure KIA Optima 2006 2.G Owner's Manual

 Keep the engine in tune and follow the
recommended periodic maintenance
schedule.
This will increase the life of all parts
and lower your operating costs.
 Do not use the air conditioner
unnecessarily.
 Slow down when driving on rough
roads.
 For longer tire life and better fuel
economy, always keep the tires
inflated to the recommended
pressures.
 Maintain a safe distance from other
vehicles to avoid sudden stops. This
will reduce wear on brake linings and
pads and save fuel because extra fuel
is required to accelerate back to
driving speed.
 Do not carry unnecessary weight in
the vehicle. Do not rest your foot on the brake
pedal while driving. This can cause
needless wear, possible damage to
the brakes, and poor fuel economy.
 Improper wheel alignment causes the
tires to roll at excessive angles,
which results in faster tire wear. It
takes more power to overcome this
improper alignment, which wastes
fuel.
 Open windows at high speeds can
reduce fuel economy.
 Crosswinds and headwinds reduce
fuel economy. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating
condition is important both for
economy and safety.
Therefore, have an Authorized Kia
Dealer perform scheduled inspections
and maintenance.
DRIVING TIPS
5-6
WARNING - Engine OFF
Motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function without the engine
running. Instead, downshift to
any appropriate gear for engine
braking effect.

5-9
 If you believe you may have gottenyour brakes wet, apply them lightly
while driving until normal braking
operation returns.WINTER DRIVING We recommend that you carryemergency equipment. Some things
you might include are tire chains, a
window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
 Make sure you have sufficient ethylene glycol coolant in the
radiator.
 Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be
in top shape to provide enough
winter starting power.
 Make sure the engine oil viscosity is suitable for cold weather.
 Check the ignition system for loose connections and damage.  Use antifreeze-formulated windshield
washer fluid and make sure you have
sufficient fluid for your trip. (Do not
use engine coolant antifreeze.)
 Do not use the parking brake if it might freeze. This is most likely to
happen after driving in slushy or wet
conditions and temperatures drop into
the freezing range. When parking,
shift to P (Park) with automatic
transaxle, or to 1 (First) or R
(Reverse) with a manual transaxle
and block the rear wheels.
SNOW TIRESWhen snow tires are used, select the size
and construction specified on the Tire
Pressure Label. It is strongly
recommended that snow tires be used on
all four wheels, or poor handling may
result. Snow tires should not be operated
at speeds exceeding 120 km/h (75 mph).
These tires should be inflated 4 psi (28
kPa, 0.3 kg/cm
2) above the recommended pressures shown on the Tire
Specification/Pressure Label, but inflation
should never exceed the maximum cold-
tire pressure shown on the tire sidewalls.
Do not install studded tires without first
checking local, provincial and municipal
regulations for possible restrictions
against their use.
WARNING - Snow Tire
Size
Snow tires should be
equivalent in size and type to
the vehicle’s standard tires.
Otherwise, the safety and
handling of your vehicle may be
adversely affected.

IMPORTANT-USE OF
COMPACT SPARE TIREYour vehicle is equipped with a compact
spare tire.
This compact spare tire takes up less
space than a regular-size tire. This tire is
smaller than a conventional tire and is
designed for temporary use only.
The compact spare should be inflated to
420kPa ( 60 psi).When using a compact spare tire,
observe the following precautions:
 Under no circumstances should you
exceed 80 km/h (50 mph); a higher
speed could damage the tire.
 Ensure that you drive slowly enough
for the road conditions to avoid all
hazards. Any road hazard, such as a
pothole or debris, could seriously
damage the compact spare.
 Any continuous road use of this tire
could result in tire failure, loss of
vehicle control, and possible personal
injury.
 Do not exceed the vehicle’s
maximum load rating or the load-
carrying capacity shown on the
sidewall of the compact spare tire.
 Avoid driving over obstacles. The
compact spare tire diameter is
smaller than the diameter of a
conventional tire and reduces the
ground clearance approximately 25
mm (1in.), which could result in
damage to the vehicle.
IN CASE OF EMERGENCY
6-20
CAUTION
 You should drive carefully when
the compact spare is in use. The
compact spare should be
replaced by the proper
conventional tire and rim at the
first opportunity.
 The operation of this vehicle is
not recommended with more
than one compact spare tire in
use at the same time.
CAUTION
This spare tire should be used only
for VERY short distances.
Compact spares should NEVER be
used for long drives or extended
distances.✻
NOTICE
Check the inflation pressure after
installing the spare tire. Adjust to
the specified pressure, as necessary.

lug nut, wrench and spare tire from
rattling while the vehicle is in motion,
store them properly.
✻
NOTICE
Check the inflation pressures as
soon as possible after installing the
spare tire. Adjust it to the specified
pressure, if necessary.
Standard Tire : 210 kPa(30 psi)

TIRES AND WHEELSTIRE CAREFor proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within the
load limits and weight distribution
recommended for your vehicle.INFLATION PRESSURESCheck all tire pressures (including the
spare) monthly when the tires are cold.
“Cold tires” means the car has not been
driven for at least three hours or driven
less than one mile (1.6 km).
Recommended pressures must be
maintained to ensure ride quality, vehicle
handling, and minimum tire wear.
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gasing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 120°F (49°C).
Wear eye protection when
checking the battery during
charging.
Disconnect the battery
charger in the following
order.
1. Turn off the battery
charger main switch.
2. Unhook the negative
clamp from the negative
battery terminal.
3. Unhook the positive clamp
from the positive battery
terminal.
✻
NOTICE
• Before performing battery
maintenance or recharging, turn
OFF all accessories and stop the
engine.
• When remounted battery,
disconnect the negative (-)
battery cable first. When re-
installing the battery, reconnect
the negative (-) battery cable
last.

This can be found on the driver side
door.
The correct tire pressure is 210 kPa (30
psi). The compact spare should be at
420kPa (60 psi).

✻
NOTICE
• Warm tires normally exceed
recommended cold tire
pressures by 28 to 41 kPa(4 to 6
psi). Do not release air from
warm tires to adjust the
pressure. The tires will become
underinflated when cold.
• Underinflation results in
excessive wear, poor handling,
reduced fuel economy, and the
possibility of blowouts from
overheated tires. Also, low tire
pressure can cause poor sealing
of the tire bead. If the tire
pressure is excessively low,
wheel deformation and/or tire
separation are possible.
Keep tire pressures at the
proper levels. If a tire frequently
needs refilling, have it checked
by an Authorized Kia Dealer or
a tire shop.
• Overinflation produces a harsh
ride, handling problems,
excessive wear at the center of
the tire tread, and a greater
possibility of damage from road
hazards.
WARNING -
Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control.
MS-CNA-Eng 7.QXD 7/25/2005 5:09 PM Page 26

7-27
TIRE ROTATIONTo equalize tread wear, it is
recommended that the tires be rotated
every 12,000km (7,500 miles) or sooner
if irregular wear develops.
During tire rotation, check the tires for
correct balance.
Check for uneven wear and damage.
Abnormal wear is usually caused by
incorrect tire pressure, improper wheel
alignment, an out-of-balance condition,
severe braking or severe cornering.Look for bumps or bulges in the tread or
side of tire. Replace the tire if you find
either of these conditions. Also, replace
the tire if you can see fabric or cord.
After rotation, be sure to bring the front
and rear tire pressures to specification
and check lug nut tightness.
Disc brake pads should be inspected for
wear whenever tires are rotated.
TIRE REPLACEMENTIf the tire is worn evenly, a tread wear
indicator will appear as a solid band,
12.7mm wide (1/2 inch) across the
tread. This shows there is less than
1.6mm (1/16 inch) of tread remaining on
the tire. Replace the tire when this
happens.
Do not wait for this band to appear
across the entire tread before replacing
the tire.
