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, which can start a fire.
WARNING: Do not start your vehicle 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: If you smell exhaust fumes inside your vehicle, have
your vehicle checked by an authorized dealer 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 miles (8 kilometers) after you
connect it. This is because the engine management system must realign
itself with the engine. You may 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.
Do not press the accelerator pedal while starting the engine. If you have
difficulty starting the engine, see Failure to startlater in this section.
KEYLESS STARTING
Note: The keyless starting system may not function if the key is close to
metal objects or electronic devices such as cellular phones.
Note: A valid key must be located inside your vehicle to switch the
ignition on and start the engine.
Note: When locking your vehicle, any remote controls left inside the
vehicle may become disabled. A message may appear in the information
display indicating that there is no key detected if you try to start the
engine. Press the unlock button on the remote control to enable it, and
then start the engine.

STARTING A GASOLINE ENGINE
When you start the engine, the idle speed increases, this helps to warm
up the engine. If the engine idle speed does not slow down automatically,
have your vehicle checked by an authorized dealer.
Note: You can crank the engine for a total of 60 seconds (without the
engine starting) before the starting system temporarily disables. The
60 seconds does not have to be all at once. For example, if you crank the
engine three times for 20 seconds each time, without the engine starting,
you reached the 60-second time limit. A message appears in the
information display alerting you that you exceeded the cranking time.
You cannot attempt to start the engine for at least 15 minutes. After
15 minutes, you are limited to a 15-second engine cranking time. You
need to wait 60 minutes before you can crank the engine for 60 seconds
again.

Important Ventilating Information
If you stop your vehicle and leave the engine idling for long periods, we
recommend that you do one of the following:
•Open the windows at least 1 inch (2.5 centimeters).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING: Failure to follow engine block heater instructions
could result in property damage or personal injury.
WARNING: Do not use your heater with ungrounded electrical
systems or two-pronged (cheater) adapters. There is a risk of
electrical shock.
Note: The heater is most effective when outdoor temperatures are below
0°F (-18°C).
The heater acts as a starting aid by warming the engine coolant. This
allows the climate control system to respond quickly. The equipment
includes a heater element (installed in the engine block) and a wire
harness. You can connect the system to a grounded 120–volt A/C
electrical source.
We recommend that you do the following for safe and correct operation:
• Use a 16-gauge outdoor extension cord that is product certified by
Underwriter’s Laboratory or Canadian Standards Association. This
extension cord must be suitable for use outdoors, in cold
temperatures, and be clearly marked Suitable for Use with Outdoor
Appliances. Never use an indoor extension cord outdoors; it could
result in an electric shock or become a fire hazard.
• Use as short an extension cord as possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the extension cord plug and the
heater cord plug connections are free and clear of water. This could
cause an electric shock or fire.
• Make sure your vehicle is parked in a clean area, clear of
combustibles.
• Make sure the heater, heater cord and extension cord are firmly
connected.
• Check for heat anywhere in the electrical hookup once the system has
been operating for approximately 30 minutes.
