Maintenance
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 oper-
ate abnormally, wire damage, battery
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.
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine exhaust and a wide variety
of automobile components and
parts, including components found
in the interior furnishings in a vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of component
wear contain or emit chemicals
known to the State of California to
cause cancer and birth defects or
other reproductive harm.
CAUTION
If you use unauthorized electric
devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety. Be careful not to install after-
market devices that may affect vehi-
cle operation.

Specifications, Consumer information, Reporting safety defects
Recommended SAE viscosity
numberEngine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (engine start and engine oil
flowability). Lower viscosity engine oils can
provide better fuel economy and cold
weather performance, however, higher vis-
cosity engine oils are required for satisfac-
tory lubrication in hot weather. Using oils of
any viscosity other than those recom-
mended could result in engine damage.When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.
CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing any lubricant. This is especially
important in dusty or sandy areas
and when the vehicle is used on
unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine
and other mechanisms that could
be damaged.
*1. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade SAE 5W-20 (API SM / ILSAC GF-4). However, if
the engine oil is not available in your country, select the proper
engine oil using the engine oil viscosity chart.
*
2. For better fuel economy, it is recommended to use the engine oil of
a viscosity grade 5W-30 (API SM / ILSAC GF-4 / ACEA A5 or
above). However, if the engine oil is not available in your country,
select the proper engine oil using the engine oil viscosity chart.
