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.
Contact an authorized dealer as soon as
possible.
Engine Fluid Temperature Management (If
Equipped)
WARNINGS
To reduce the risk of crash and injury,
be prepared that the vehicle speed
may reduce and the vehicle may not be able
to accelerate with full power until the fluid
temperatures reduce.
Never remove the coolant reservoir
cap while the engine is running or hot.
Your vehicle can pull a trailer, but because
of the added load, your vehicle’s engine may
temporarily reach higher temperatures during
severe operating conditions such as
ascending a long or steep grade while
pulling a trailer in high temperatures.
At this time, you may notice your engine
coolant temperature gauge needle move
toward the H and the POWER REDUCED TO
LOWER TEMP message may appear in the
information display.
You may notice a reduction in vehicle speed
caused by reduced engine power. In order
to manage the engine fluid temperatures,
your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place. The amount of speed reduction
depends on many factors such as vehicle
loading, towing, grade and ambient
temperature. If this occurs, there is no need
to pull off the road. You can continue to drive
your vehicle while this message is active.
The air conditioning may also cycle on and
off during severe operating conditions to
protect overheating of the engine. When the
engine coolant temperature decreases to a
normal operating temperature, the air
conditioning will turn on once again.
If the engine coolant temperature gauge
moves fully into the red (hot) area, or if the
coolant temperature warning or service
engine soon messages appear in your
information display:
1. Pull off the road as soon as safely
possible and shift the transmission into
P.
2. Leave the engine running until the
coolant temperature gauge needle
moves away from the red (hot) area. After
several minutes, if the temperature does
not drop, follow the remaining steps.
3. Switch the engine off and wait for it to
cool before checking the coolant level.
4. If the coolant level is normal, restart your
engine and continue.
5. If the coolant is low, add coolant, and
restart the engine. See Adding Engine
Coolant or How Fail-Safe Cooling Works
in this chapter for more information.
