GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage.
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire.
WARNING: Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic.
Always open the garage door before you
start the engine.
WARNING: Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately 5.0 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You can
disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine.
If your vehicle is operated in a heavy snow
storm or blowing snow conditions, the
engine air induction may become partially
clogged with snow and ice. If this occurs,
the engine may experience a significant
reduction in power output. At the earliest
opportunity, clear all the snow and ice
away from the air induction inlet.
