Engine Coolant Heater
Your vehicle may be equipped with this feature.
In very cold weather, 0°F (–18°C) or colder, the engine
coolant heater can help. You’ll 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.
To Use the Engine Coolant Heater
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
The cord is located in the engine compartment
behind the underhood fuse block on the driver’s side
of the vehicle.
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 don’t, 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’ll be parking
your vehicle. The dealer can give you the best advice for
that particular area.

Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
If the gage pointer is near the top of the gage, the
engine is too hot. It means that your engine coolant has
overheated. If you have been operating your vehicle
under normal driving conditions, you should pull off the
road, stop your vehicle and turn off the engine as
soon as possible.
SeeEngine Overheating on page 5-28for more
information.
Malfunction Indicator Lamp
Check Engine Light
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system is called OBD II (On-Board Diagnostics-
Second Generation) and is intended to assure that
emissions are at acceptable levels for the life of
the vehicle, helping to produce a cleaner environment.
The check engine light comes on to indicate that
there is a problem and service is required. Malfunctions
often will be indicated by the system before any
problem is apparent. This may prevent more serious
damage to your vehicle. This system is also designed to
assist your service technician in correctly diagnosing
any malfunction.

Language
You can choose the language in which the DIC
information is displayed. Press the reset stem until
LANGUAGE is displayed. While LANGUAGE is on
the display, press and hold the reset stem until
the language changes from ENGLISH to the language
you desire. You can choose from English, Spanish,
or French.
DIC Warnings and Messages
Warning messages are displayed on the DIC to notify
the driver that the status of the vehicle has changed and
that some action may be needed by the driver to
correct the condition. More than one message may
appear at one time. They will appear one after the other.
The messages are displayed for three seconds each.
Some messages may not require immediate action
but you should press and release the trip odometer reset
stem to acknowledge that you received the message
and clear it from the display. Each message must
be acknowledged individually. Some messages cannot
be cleared from the display because they are more
urgent. These messages require action before they can
be removed from the DIC display. The following are
the possible messages that can be displayed and some
information about them.
AC (Air Conditioning) OFF
This message will be displayed when the engine coolant
temperature is too high and the air conditioning in
your vehicle needs to be turned off. See andEngine
Overheating on page 5-28andClimate Control System
on page 3-18for more information. It will be displayed
along with the ENG HOT message.
ABS (Anti-Lock Brake System)
This message will be displayed on the DIC if there is a
problem with your antilock brake system. Check your
antilock brake system as soon as possible and have
your vehicle serviced. SeeBrakes on page 5-38
andAnti-Lock Brake System Warning Light on
page 3-29for more information. Pressing the reset
stem to acknowledge this message and clear it from
the DIC display.

This message will be displayed when there is a problem
with your vehicle’s battery. SeeBattery on page 5-41
andBattery Warning Light on page 3-27for more
information.
3-39

This message will be displayed on the DIC if there is a
problem with your brakes. Check your brakes as
soon as possible and have your vehicle serviced.
SeeBrakes on page 5-38andBrake System Warning
Light on page 3-28for more information. Press and
release the reset stem to acknowledge the message and
clear it from the DIC display.
CHANGE OIL
This message will be displayed on your DIC when the
oil needs to be changed. Check the oil in your vehicle as
soon as possible and have your vehicle serviced. See
Engine Oil on page 5-13andScheduled Maintenance on
page 6-4for more information. Press the reset stem
to acknowledge the message and clear it from the
display.
DOORS
This message will be displayed on your DIC when one
of your doors is ajar. You should check all the doors
on your vehicle to make sure they are closed. Press the
reset stem to acknowledge the message and clear it
from the display.
ENG (Engine) HOT
This message will be displayed on your DIC when your
engine coolant temperature is hot. Check your engine
coolant temperature gage. SeeEngine Coolant
Temperature Gage on page 3-30for more information.
You should have your vehicle serviced as soon as
possible if you suspect your engine is overheating. See
Engine Overheating on page 5-28for more information.
FLUID
This message will be displayed on the DIC if your brake
uid is low. Check the brake uid as soon as possible
and have your vehicle serviced. SeeBrakes on
page 5-38for more information. Press the reset stem to
acknowledge the message and clear it from the DIC
display.
FUEL CAP
This message will be displayed if your vehicle’s fuel cap
is either off or loose. You should pull over and check

Press the reset stem to acknowledge the message and
clear it from the display.
3-40
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade. If you don’t shift
down, you might have to use your brakes so much that
they would get hot and no longer work well.
When towing at high altitude on steep uphill grades,
consider the following: Engine coolant will boil at a lower
temperature than at normal altitudes. If you turn your
engine off immediately after towing at high altitude
on steep uphill grades, your vehicle may show signs
similar to engine overheating. To avoid this, let the
engine run while parked (preferably on level ground)
with the automatic transmission in PARK (P) (or the
manual transmission out of gear and the parking brake
applied) for a few minutes before turning the engine
off. If you do get the overheat warning, seeEngine
Overheating on page 5-28.
Parking on Hills
{CAUTION:
You really should not park your vehicle, with a
trailer attached, on a hill. If something goes
wrong, your rig could start to move. People
can be injured, and both your vehicle and the
trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual
transmission. When parking uphill, turn your
wheels away from the curb. When parking downhill,
turn your wheels into the curb.
2. Have someone place chocks under the trailer
wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
