Vehicles driven year-round in non-extreme
climates should use prediluted engine
coolant for optimum cooling system and
engine 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 outside temperatures, vehicle
load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine
coolant temperature gauge moves to the
red (hot) area and:
A high engine temperature
message appears in the
information display.
The service engine soon
indicator appears in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
If this occurs, your vehicle still operates.
However:
•
The engine power becomes limited.
•
The air conditioning system becomes
disabled.
Continued operation increases the engine
temperature and the engine completely
shuts down, causing steering and braking
effort to increase.
Once the engine temperature cools, the
engine can be re-started. Take your vehicle
to an authorized dealer as soon as possible
to minimize engine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use during
emergencies only. Operate your
vehicle in fail-safe mode only as long
as necessary to bring your vehicle to rest
in a safe location and seek immediate
repairs. When in fail-safe mode, your
vehicle has limited power, does not
maintain high-speed operation and may
completely shut down without warning.
Potentially losing power steering assist,
and power brake assist, which may
increase the possibility of a crash resulting
in serious injury.
Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle has limited engine power,
drive your vehicle with caution. Your vehicle
does not maintain high-speed operation
and the engine operates poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1.
Pull off the road as soon as safely
possible and switch off the engine.
2. Tow your vehicle to an authorized
dealer.
3. If this is not possible, wait a short
period for the engine to cool.
4. Check the coolant level and add if low.
5. Re-start the engine and drive your
vehicle to an authorized dealer.
Note:
Driving your vehicle without repair
increases the chance of engine damage. See
an authorized dealer as soon as possible.
