To prevent electrical shock, do not use your heater with
ungrounded electrical systems or two-pronged (cheater)
adapters.
Guarding against exhaust fumes
Although odorless and colorless, carbon monoxide is present in exhaust
fumes. Take precautions to avoid its dangerous effects.
If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
•the vehicle is raised for service.
•the sound of the exhaust system changes.
•the vehicle has been damaged in a collision.
Engine exhaust, some of its constituents, and certain vehicle
components contain or emit chemicals known to the State of
California to cause cancer, and birth defects or other reproductive
harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.

Have your dealer check the engine cooling system for leaks if you have
to add more than 1.0 liter (1.0 quart) of engine coolant per month.
Severe winter climate
If you drive in extremely cold climates (less than –36°C [–34°F]), it may
be necessary to increase the coolant concentration above 50%. Refer to
the chart on the coolant container to ensure the coolant concentration in
your vehicle is such that the coolant will not freeze at the temperature
level in which you drive during winter months. Never increase the
coolant concentration above 60%. Increased engine coolant
concentrations above 60% will decrease the freeze protection
characteristics of the engine coolant. Vehicles driven year-round in
non-extreme climates should use a 50/50 mixture of engine coolant and
distilled water for optimum freeze protection.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
•the engine coolant temperature
gauge will move to the red (hot)
area.
•the
symbol will illuminate.
•the
symbol will illuminate.
•theService Engine Soon
indicator light will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate, however:
•the engine power will be limited.
•the air conditioning system will be disabled.
