WARNING!
A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact
with your exhaust system. Do not park or oper-
ate your vehicle in areas where your exhaust
system can contact anything that can burn.
In unusual situations involving grossly malfunc-
tioning engine operation, a scorching odor may
suggest severe and abnormal catalyst overheat-
ing. If this occurs, stop the vehicle, turn off the
engine and allow it to cool. Service, including a
tune up to manufacturer's specifications, should
be obtained immediately.
To minimize the possibility of catalytic converter
damage:
• Do not shut off the engine or interrupt the
ignition when the transmission is in gear and
the vehicle is in motion.
• Do not try to start the engine by pushing or
towing the vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diag-
nostic testing.
• Do not idle the engine for prolonged periods
during very rough idle or malfunctioning oper-
ating conditions.
• Do not allow vehicle to run out of fuel.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
Battery
The low-maintenance battery may require the
addition of water at intervals depending on ve-
hicle usage. In temperatures up to 32°C (90°F),
check the battery fluid level at least every 12
months or 24 000 km (15,000 miles). At higher
temperatures, check more often. For severe ser-
vice vehicles, check at 12 000 km (7,500 miles).
WARNING!
Do not charge a battery or jump start a vehicle
with a clear battery charge indicator. If the
battery charge indicator is clear, the fluid in the
battery is low (add distilled water). Charging a
battery or jump starting a vehicle with a clear
battery charge indicator could cause serious
injury.
Keep the battery terminals clean and free from
corrosion by cleaning them periodically with a
solution of baking soda and water.
CAUTION!
Keep battery fluid and any deposits removed
from the battery connections away from paint,
sheet metal and plastics. Damage to these
materials could result.
WARNING!
Battery posts, terminals, and related accesso-
ries contain lead and lead compounds. Always
wash hands after handling the battery.
WARNING!
Handled improperly, batteries can be danger-
ous. Follow these precautions when servicing
your battery:
• Use extreme care when servicing the battery.
Battery fluid contains sulfuric acid and must be
kept from the eyes and skin. Safety glasses,
rubber gloves and protective clothing are rec-
ommended. If acid contacts eyes or skin, flush
immediately with large amounts of water. Get
emergency medical attention immediately.
