Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
to Refill capacities in this section.
Fill your engine coolant reservoir as outlined in Adding engine coolant
in this section.
Severe climates
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 will provide adequate freeze protection.
Never increase the engine coolant concentration above 60%
(protection to –60°F). At a level over 60%, your engine could overheat
and become damaged.
If you drive in extremely hot climates, it is still necessary to maintain the
coolant concentration at 50/50 coolant and water. Do not allow the
coolant concentration to fall below 40% coolant. At a concentration
less than 40%, the corrosion protection to your engine and cooling
components may be compromised and permanent damage may result.
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 H (hot)
area.
• The
symbol will
illuminate.
• The

• The
