Notice: If the pressure cap is not
tightly installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
If the coolant is not at the proper
level when the system cools down
again, see your dealer.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There are two engine hot messages
that may be displayed in the Driver
Information Center (DIC). See
Engine Cooling System Messages
on page 5‑34 for more information.
You may decide not to lift the hood
when one of these warnings appear,
but get service help right away. See
Roadside Service (U.S. and
Canada) on page 13‑7 or Roadside
Service (Mexico) on page 13‑9.
If you do decide to lift the hood,
make sure the vehicle is parked on
a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fan(s)
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
Notice: Running the engine
without coolant may cause
damage or a fire. Vehicle damage
would not be covered by the
warranty. See Overheated Engine
Protection Operating Mode on
page 10‑22 for information on
driving to a safe place in an
emergency.

off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of

could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.
If No Steam Is Coming from
the Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.
Climbs a long hill on a hot day.
.
Stops after high-speed driving.
