Engine Coolant Heater
If your vehicle has this feature, in very cold
weather 0°F (−18°C) or colder, the engine coolant
heater can help. You will get easier starting
and better fuel economy during engine warm-up.
Usually, the coolant heater should be plugged
in a minimum of four hours prior to starting your
vehicle. At temperatures above 32°F (0°C),
use of the coolant heater is not required. Your
vehicle may also have an internal thermostat
in the plug end of the cord. This will prevent
operation of the engine coolant heater when
the temperature is at or above 0°F (−18°C)
as noted on the cord.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical
cord. The cord is located on the passenger’s
side of the engine compartment, near the
radiator.
3. Plug it into a normal, grounded 110-volt AC
outlet.
{CAUTION:
Plugging the cord into an ungrounded
outlet could cause an electrical shock.
Also, the wrong kind of extension cord
could overheat and cause a re. You
could be seriously injured. Plug the cord
into a properly grounded three-prong
110-volt AC outlet. If the cord will not
reach, use a heavy-duty three-prong
extension cord rated for at least 15 amps.
4. Before starting the engine, be sure to unplug
and store the cord as it was before to keep it
away from moving engine parts. If you do
not, it could be damaged.
How long should you keep the coolant heater
plugged in? The answer depends on the outside
temperature, the kind of oil you have, and some
other things. Instead of trying to list everything here,
we ask that you contact your dealer in the area
where you will be parking your vehicle. The dealer
can give you the best advice for that particular area.

closed completely. Make sure that the liftgate is
closed completely. SeeLiftgate on page 107.
OIL PRSSURE (Pressure) LOW STOP
ENGINE
Notice:If you drive your vehicle while the
engine oil pressure is low, severe engine
damage may occur. If a low oil pressure
warning appears on the Driver Information
Center (DIC), stop the vehicle as soon as
possible. Do not drive the vehicle until the
cause of the low oil pressure is corrected. See
Engine Oil on page 344for more information.
This message displays when the vehicle’s
engine oil pressure is low. The oil pressure light
also appears on the instrument panel cluster.
SeeOil Pressure Light on page 186.
Stop the vehicle immediately, as engine damage
can result from driving a vehicle with low oil
pressure. Have the vehicle serviced by your dealer
as soon as possible when this message is

Checking Things Under
the Hood
{CAUTION:
An electric fan under the hood can start up
and injure you even when the engine is not
running. Keep hands, clothing, and tools
away from any underhood electric fan.
{CAUTION:
Things that burn can get on hot engine
parts and start a re. These include
liquids like fuel, oil, coolant, brake uid,
windshield washer and other uids, and
plastic or rubber. You or others could be
burned. Be careful not to drop or spill
things that will burn onto a hot engine.
Hood Release
To open the hood, do the following:
1. Pull the handle with
this symbol on it. It is
located inside the

If Steam Is Coming From Your Engine
{CAUTION:
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. 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 vehicles
engine is overheated, the liquids in it can
catch re. You or others could be badly
burned. Stop your engine if it overheats,
and get out of the vehicle until the engine
is cool.
SeeOverheated Engine Protection
Operating Mode on page 357for
information on driving to a safe place
in an emergency.Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty. See
Overheated Engine Protection Operating Mode
on page 357for information on driving to a
safe place in an emergency.
If No Steam Is Coming From
Your Engine
An overheat warning can indicate a serious
problem.
If you get an engine overheat warning, but see or
hear no steam, the problem may not be too
serious. Sometimes the engine can get a little too
hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
356

If you get the overheat warning with no sign of
steam, try this for a minute or so:
1. If the air conditioner is on, turn it off.
2. Turn on your heater to full hot at the highest fan
speed and open the windows as necessary.
3. Try to minimize engine load. If you are in a
traffic jam, shift to NEUTRAL (N); otherwise,
shift to the highest gear while driving.
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for
about ten minutes. If the warning does not come
back on, you can drive normally.
If the warning continues and you have not stopped,
pull over, stop, and park your vehicle right away.
If there is still no sign of steam, you can idle the
engine for three minutes while you are parked.
If you still have the warning, turn off the engine
and get everyone out of the vehicle until it
cools down. Also, see “Overheated Engine
Protection Operating Mode” later in this section.
You may decide not to lift the hood but to get
service help right away.Overheated Engine Protection
Operating Mode
This emergency operating mode lets your vehicle
be driven to a safe place in an emergency situation.
If an overheated engine condition exists, an
overheat protection mode which alternates ring
groups of cylinders helps prevent engine damage.
In this mode, there is a signicant loss in power and
engine performance. The temperature gage
indicates an overheat condition exists. Driving
extended miles (km) and/or towing a trailer in the
overheat protection mode should be avoided.
Notice:After driving in the overheated engine
protection operating mode, to avoid engine
damage, allow the engine to cool before
attempting any repair. The engine oil will be
severely degraded. Repair the cause of coolant
loss, change the oil and reset the oil life system.
SeeEngine Oil on page 344.

3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the
cigarette lighter or the accessory power outlet.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save
both batteries. And it could save your radio!
4. Open the hoods and locate the positive (+)
and negative (−) terminal locations on each
vehicle.
You will not need to access your battery for
jump starting. Your vehicle has a remote
positive (+) and a remote negative (−) jump
starting terminal for that purpose.
The remote positive (+)
terminal is located
under the engine
compartment fuse block
cover, and is marked
with a plus (+) symbol
on the cover. To access
the terminal, remove
the fuse block cover.The remote negative (−)
terminal is located in the
front of the engine
compartment, near the
engine oil dipstick.
SeeEngine Compartment Overview on
page 342for more information on the location
of the remote positive (+) terminal and the
engine oil dipstick.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
