ECONOMICAL OPERATION
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 kilometers (miles) you can get from a liter (gallon) of fuel. To operate
your vehicle as economically as possi‐
ble, use the following driving sugges‐ tions to help save money in both fuel
and repairs: • Drive smoothly. Accelerate at a mod‐ erate rate. Do not make "jack-rabbit"
starts or full-throttle shifts and maintain a steady cruising speed. Do
not race between stop lights. Try to
adjust your speed to the traffic so
you do not have to change speeds
unnecessarily. Avoid heavy traffic whenever possible.
Always maintain a safe distance from
other vehicles so you can avoid un‐
necessary braking. This also reduces
brake wear.
• Drive at a moderate speed. The fast‐ er you drive, the more fuel your vehi‐cle uses. Driving at a moderate
speed, especially on the highway, is
one of the most effective ways to re‐
duce fuel consumption. • Do not "ride" the brake or clutch ped‐
al. 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 consequences.
• Take care of your tires. Keep them inflated to the recommended pres‐
sure. Incorrect inflation, either too
much or too little, results in unneces‐
sary tire wear. Check the tire pres‐ sures at least once a month.
• Be sure that the wheels are aligned correctly. Improper alignment can re‐
sult from hitting curbs or driving too
fast over irregular surfaces. Poor alignment causes faster tire wear
and may also result in other prob‐
lems as well as greater fuel con‐
sumption.
• Keep your vehicle in good condition. For better fuel economy and reducedmaintenance costs, maintain your ve‐
hicle in accordance with the mainte‐
nance schedule in Chapter 9, Mainte‐
nance. If you drive your vehicle in se‐
vere conditions, more frequent main‐ tenance is required (see Chapter 9,
Maintenance for details). • Keep your vehicle clean. For maxi‐
mum service, your vehicle should be
kept clean and free of corrosive ma‐ terials. 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 al‐ so contribute to corrosion.
• Travel lightly. Do not carry unneces‐ sary weight in your vehicle. Weight
reduces fuel economy.
• Do not let the engine idle longer than necessary. If you are waiting (and notin traffic), turn off your engine and
restart only when you're ready to go.
• Remember, your vehicle does not re‐ quire extended warm-up. After the
engine has started, allow the engine
to run for 10 to 20 seconds prior to placing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warmup period.
• Do not "lug" or "over-rev" the engine. Lugging is driving too slowly in too
high a gear resulting engine bucking.
If this happens, shift to a lower gear. Over-revving is racing the engine be‐
yond its safe limit. This can be avoi‐
ded by shifting at the recommended
speeds.

NORMAL MAINTENANCE SCHEDULE - FOR GASOLINE ENGINE [FOR EUROPE (EXCEPT RUSSIA)]
The following maintenance services must be performed to ensure good emission control and performance. Keep receipts for
all vehicle emission services to protect your warranty. Where both mileage and time are shown, the frequency of service is determined by whichever occurs first.
NO.ITEMREMARK
*1 Coolant (Engine / Inverter) When adding coolant, use only deionized water or soft water for your vehicle
and never mix hard water in the coolant filled at the factory. An improper
coolant mixture can result in serious malfunction or engine damage.
*2 Engine oil and engine oil filter Check the engine oil level and leak every 500 km (350 miles) or before start‐ing a long trip.
*3 Fuel additives (Gasoline) Kia recommends that you use unleaded gasoline which has an octane rating
of RON (Research Octane Number) 95 / AKI (Antiknock Index) 91 or higher
(for Europe) or Octane Rating of RON (Research Octane Number) 91 / AKI(Antiknock Index) 87 or higher (except Europe).
For customers who do not use good quality gasolines including fuel additives
regularly, and have problems starting or the engine does not run smoothly,
one bottle of additives added to the fuel tank at every 15,000 km (for Eu‐rope, Australia and New Zealand)/10,000 km (except Europe, Australia andNew Zealand).
Additives are available from your authorized Kia dealer along with informa‐
tion on how to use them. Do not mix other additives.
*4 HSG (Hybrid Starter & Generator) belt Inspect HSG belt for evidence of cuts, crocks, excessive wear or oil saturation
and replace if necessary. If drive belt noise occurred, readjust drive belt ten‐
sion before replace.
*5 Spark plug For your convenience, it can be replaced prior to it's interval when you domaintenance of other items.
