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 will have
limited power, will not be able to maintain
high-speed operation, and may completely
shut down without warning, potentially losing
engine power, 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 when
in the fail-safe mode. 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.
