10-30 Vehicle Care
WARNING (Continued)
See Overheated Engine
Protection Operating Mode on
page 10 30 for information on
driving to a safe place in an
emergency.
If No Steam is Coming from
the Engine
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
Idles for long periods in traffic
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to
N (Neutral) while stopped. If it is
safe to do so, pull off the road,
shift to P (Park) or N (Neutral)
and let the engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle
right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see Overheated
Engine Protection Operating Mode
next in this section.

Overheated Engine

Protection

Operating Mode

This emergency operating mode lets
the vehicle be driven to a safe
place, up to 80 km (50 mi), in an
emergency situation. If an
overheated engine condition exists
and the messages COOLANT
OVER TEMPERATURE and
REDUCED ENGINE POWER are
displayed, along with the check
engine light, an overheat protection
mode which alternates firing groups
of cylinders helps prevent engine
damage. In this mode, there is a
significant loss in power and engine
performance.
Driving extended distances in the
overheat protection mode should be
avoided.
