refer to
Refill capacities
in the
Capacities and specifications
chapter.
Have your dealer check the engine
cooling system for leaks if you
have to add more than a liter
(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 engine
coolant concentration above 60%.
Leave a 50/50 mixture of engine
coolant and water in your vehicle
year-round in non-extreme
climates.
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.
