3-56 Instrument Panel

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
Because of the added load of the
trailer, the vehicle’s engine may
overheat on hot days, when going up
a long or steep grade with a trailer. If
the engine coolant temperature gage
indicates overheating, turn off the air
conditioning to reduce engine load,
pull off the road and stop in a safe
spot. Let the engine run while
parked, preferably on level ground,
with the transmission in P (Park) for
a few minutes before turning the
engine off.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.
On a long uphill grade, shift down
and reduce the vehicle speed
to around 55 mph (88 km/h) to
reduce the possibility of the engine
and the transmission overheating.

Trailer Wiring Harness
The vehicle is equipped with the
following wiring harness for towing
a trailer.
Basic Trailer Wiring
The trailer wiring harness, with a
seven-pin connector, is located at
the rear of the vehicle and is tied to
the vehicle’s frame. The harness
connector can be plugged into a
seven-pin universal heavy-duty
trailer connector available through
your dealer/retailer.The seven-wire harness contains
the following trailer circuits:Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn
Signal
Brown: Taillamps
Black: Ground
Light Green: Back-up Lamps
Red/Black: Battery Feed
Dark Blue: Trailer Brake*
*The fuse for this circuit is installed
in the underhood electrical center,
but the wires are not connected.
They should be connected by your
dealer/retailer or a qualied
service center.If the back-up lamp circuit is
not functional, contact your
dealer/retailer.
If a remote (non-vehicle) battery is
being charged, press the Tow/Haul
mode switch located on the center
console near the climate controls.
This will boost the vehicle system
voltage and properly charge the
battery. If the trailer is too light for
Tow/Haul mode, turn on the
headlamps (Non-HID only) as a
second way to boost the vehicle
system and charge the battery.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 5-20.

Engine Coolant
The cooling system in the vehicle is
lled with DEX-COOL®engine
coolant. The coolant is designed to
remain in the vehicle for ve years
or 150,000 miles (240 000 km),
whichever occurs rst.
The following explains the cooling
system and how to check and
add coolant when it is low. If there
is a problem with engine
overheating, seeEngine
Overheating on page 5-20.
What to Use
{CAUTION
Adding only plain water to the
cooling system can be dangerous.
Plain water, or some other liquid
such as alcohol, can boil before
the proper coolant mixture will.
(Continued)
CAUTION (Continued)
The vehicle’s coolant warning
system is set for the proper
coolant mixture. With plain water
or the wrong mixture, the engine
could get too hot but you would
not get the overheat warning. The
engine could catch re and you or
others could be burned. Use a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant.
Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
coolant. If using this mixture, nothing
else needs to be added. This
mixture:
Gives freezing protection down to
−34°F (−37°C), outside
temperature.
Gives boiling protection up to
265°F (129°C), engine
temperature.
Protects against rust and
corrosion.
Will not damage aluminum parts.
Helps keep the proper engine
temperature.
Notice:If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle warranty.
Too much water in the mixture
can freeze and crack the engine,
radiator, heater core, and
other parts.
Notice:If extra inhibitors and/or
additives are used in the
vehicle’s cooling system, the
vehicle could be damaged. Use
only the proper mixture of
the engine coolant listed in this
manual for the cooling system.
SeeRecommended Fluids
and Lubricants on page 6-12for
more information.
Service and Appearance Care 5-17

6. Fill the coolant recovery tank to
the FULL COLD mark.
7. Reinstall the cap on the coolant
recovery tank but leave the
radiator pressure cap off.8. Start the engine and let it run
until the upper radiator hose
feels warm. Any time during this
procedure, watch out for the
engine cooling fan(s).
9. If the coolant level inside the
radiator ller neck is low, add
more of the proper DEX-COOL
coolant mixture through the
ller neck until the level is back
up to the base of the ller
neck. Replace the pressure cap.
Be sure to secure it tightly.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.
Engine Overheating
The vehicle has several indicators
to warn of engine overheating.
There is an engine coolant
temperature gage on the instrument
panel cluster. SeeEngine Coolant
Temperature Gage on page 3-35.
The vehicle may also display
an ENGINE OVERHEATED
IDLE ENGINE and ENGINE
OVERHEATED STOP ENGINE
message in the Driver Information
Center (DIC). SeeDIC Warnings
and Messages on page 3-48.
You may decide not to lift the hood
when this warning appears, but
instead get service help right away.
SeeRoadside Assistance Program
on page 7-6.
5-20 Service and Appearance Care

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, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:If the engine catches re
while driving with no coolant,
the vehicle can be badly
damaged. The costly repairs
would not be covered by
the vehicle warranty. See
Overheated Engine Protection
Operating Mode on page 5-22for
information on driving to a
safe place in an emergency.If Steam Is Coming From The
Engine Compartment
{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 the engine if it overheats,
and get out of the vehicle until the
engine is cool.
SeeOverheated Engine Protection
Operating Mode on page 5-22for
information on driving to a safe
place in an emergency.
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.
Idles for long periods in traffic.
Tows a trailer.
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), otherwise, shift
to the highest gear while
driving—D(Drive) or L (Low).
