open gas tank KIA Rio 2016 3.G Owner's Manual

13
Introduction
Your new Kia vehicle is designed to use
only unleaded fuel having a pump octane
number ((R+M)/2) of 87 (Research
Octane Number 91) or higher. (Do not
use methanol blended fuels)
Your new vehicle is designed to obtain
maximum performance with UNLEADED
FUEL, as well as minimize exhaust emis-
sions and spark plug fouling.

NOTICE
Tighten the cap until it clicks one time,
otherwise the fuel cap open warning
indicator will illuminate.
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Pursuant to EPA regulations, ethanol
may be used in your vehicle. Do not use
gasohol containing more than 10%
ethanol, and do not use gasoline or
gasohol containing any methanol.
Ethanol provides less energy than gaso-
line and it attracts water, and it is thus
likely to reduce your fuel efficiency and
could lower your MPG results. Methanol
may cause drivability problems and dam-
age to the fuel system, engine control
system and emission control system.
Discontinue using gasohol of any kind if
drivability problems occur. Vehicle dam-
age or drivability problems may not be
covered by the manufacturer's warranty if
they result from the use of:
1. Gasoline or gasohol containing methanol.
2. Leaded fuel or leaded gasohol.
FUEL REQUIREMENTS
WARNING - Refueling
• Do not "top off" after the nozzle automatically shuts off when
refueling.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an accident.
CAUTION
Never add any fuel system cleaningagents to the fuel tank other thanwhat has been specified. (Werecommand that you consult anauthorized Kia dealer for details.)

Maintenance
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es so that evaporated fuel is not taken
into the engine. After the engine warms
up during ordinary driving, the PCSV
opens to introduce evaporated fuel to the
engine.
3. Exhaust emission control system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
This vehicle should not be modified.
Modification of your vehicle could affect
its performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
If you use unauthorized electronic
devices, it may cause the vehicle to
operate abnormally, wire damage, bat-
tery discharge and fire. For your safety,
do not use unauthorized electronic
devices.
Engine exhaust gas precautions(carbon monoxide)
Carbon monoxide can be present with other exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately. If you ever sus-
pect exhaust fumes are coming into
your vehicle, drive it only with all the
windows fully open. Have your vehicle
checked and repaired immediately.
WARNING- Exhaust
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions on this
page to avoid CO poisoning.
