Engine Coolant Heater
The engine coolant heater can
provide easier starting and better
fuel economy during engine
warm-up in cold weather conditions
at or below 0°F (−18°C). Vehicles
with an engine coolant heater should
be plugged in at least four hours
before starting. An internal
thermostat in the plug-end of the
cord may exist which will prevent
engine coolant heater operation
at temperatures above 0°F (−18°C).
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 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 to prevent damage.
The length of time the heater should
remain plugged in depends on
several factors. Ask a dealer/retailer
in the area where you will be
parking the vehicle for the best
advice on this.
Automatic Transmission
Operation
The automatic transmission has a
shift lever on the console.

the regular brakes. SeeBrake
System Warning Light on page 3-27.
For vehicles with a Driver
Information Center (DIC), seeDIC
Warnings and Messages on
page 3-37for all brake related DIC
messages.
StabiliTrak®/Traction
Control System (TCS)
Warning Light
The StabiliTrak system or the
Traction Control System (TCS)
indicator/warning light comes
on briey while starting the engine.
If it does not, have the vehicle
serviced by your dealer/retailer. If
the system is working normally
the indicator light will then go off.The indicator/warning light ashes
while the StabiliTrak or TCS system
is working to control the vehicle
on a low traction surface.
If the TCS warning light comes on
and stays on while driving, the
vehicle needs service.
The light comes on when the TCS
and the StabiliTrak system is
turned off. If the TCS is off, wheel
spin is not limited. If the StabiliTrak
system is off, the system does
not assist in controlling the vehicle.
Turn on the TCS and the
StabiliTrak system and the warning
light turns off.

information
Engine Coolant
Temperature Gage
This gage shows the engine coolant
temperature.
If the gage pointer is in the shaded
area of the gage, the engine is
too hot. It means that the engine
coolant has overheated. If the
vehicle has been operating under
normal driving conditions, pull off the
road, stop your vehicle and turn
off the engine as soon as possible.
SeeEngine Overheating on
page 5-27for more information.

DIC Warnings and
Messages
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.
Multiple messages may appear one
after another. The messages are
displayed for several 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 messages and toclear them from the display. Each
message must be acknowledged
individually.
Some messages cannot be cleared
from the DIC display because
they are more urgent. These
messages require action before they
can be cleared. You should take
any messages that appear on
the display seriously and remember
that clearing the messages only
makes the messages disappear, not
correct the problem.
The following are the possible
messages that can be displayed
and some information about them.
AC (Air Conditioning) OFF
This message displays when
the engine coolant temperature is
too high and the air conditioning
in the vehicle needs to be turned off.
SeeEngine Overheating on
page 5-27andClimate Control

information. This message displays
along with the ENG HOT message.
ABS (Antilock Brake System)
FAULT
This message displays if there is a
problem with the Antilock Brake
System (ABS). Check the ABS as

Making Turns
Notice:Making very sharp turns
while trailering could cause
the trailer to come in contact with
the vehicle. The vehicle could
be damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal. Do this
so the trailer won’t strike soft
shoulders, curbs, road signs, trees
or other objects. Avoid jerky or
sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a
Trailer
The arrows on the instrument panel
ash whenever signaling a turn
or lane change. Properly hooked up,
the trailer lamps also ash, telling
other drivers the vehicle is turning,
changing lanes or stopping.When towing a trailer, the arrows
on the instrument panel ash
for turns even if the bulbs on the
trailer are burned out. For this
reason you may think other drivers
are seeing the signal when they
are not. It is important to check
occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower
gearbeforestarting down a long
or steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well.
Vehicles with an automatic
transmission can tow in D (Drive).
Shift the transmission to a lower
gear if the transmission shifts
too often under heavy loads and/or
hilly conditions. For vehicles with
a manual transmission, it is
better not to use the highest gear.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 the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the 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 P (Park) for a
few minutes before turning the
engine off. For vehicles with manual
transmissions, let the engine run
while parked, preferably on
level ground, with the transmission
out of gear and the parking
brake applied, for a few minutes
before turning the engine off. If the
overheat warning comes on,
seeEngine Overheating on
page 5-27.
