If Steam is Coming from the
Engine Compartment
Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.

Overheated Engine

Protection

Operating Mode

The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level:
The engine coolant temperature
warning light will illuminate.
Engine power may be reduced.
The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
Engine power and under certain
conditions, vehicle speed will
decrease. Vehicle speed can be
controlled with the accelerator
pedal, but the vehicle may not
accelerate at the desired speed.
Vehicle Care
The transmission will downshift or
upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and
engine coolant temperature is
reduced, vehicle speed can be
increased using the accelerator
pedal, and air conditioning cooling
function will automatically be turned
back ON.
If:
1. The engine coolant temperature
is not reduced.
2. The air conditioning cooling
function does not turn back ON.
3. The engine oil pressure low/
engine coolant temperature high
warning light illuminates, this
may indicate a malfunction.
Move the vehicle off the road in
a safe area and allow the engine
to cool. If after checking the oil
and coolant, the oil pressure
