Maintenance
Recommended engine coolant
When adding coolant, use onlydeionized water, distilled 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 severe malfunction or
engine damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an phosphate-based
ethylene glycol coolant to preventcorrosion and freezing.
Do not use alcohol or methanol coolant or mix them with the spec-ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of thesolution. For mixing percentage, refer to the
following table:
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each.
It is suitable to use for most tempera-
ture ranges of -31°F and higher.

trusions inside the coolant
cap should be securely inter-
locked.

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 surgetank through the purge control sole-
noid valve.
Purge Control Solenoid Valve(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module (ECM); when the engine
coolant temperature is low during
idling, the PCSV closes so that evap-
orated 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 per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to theemission system.
Vehicle modifications
This vehicle should not be modi-fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
Engine exhaust (carbon monox-
ide) precautions
Carbon monoxide can be present with other exhaust fumes. If you
smell exhaust fumes of any kind in
your vehicle, drive with all the win-
dows fully open. Have your vehicle
checked and repaired immediately.
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
on this page to avoid CO poi-soning.
