Engine Cooling System
Messages
ENGINE HOT A/C (Air
Conditioning) OFF
This message displays when the
engine coolant becomes hotter than
the normal operating temperature.
To avoid added strain on a hot
engine, the air conditioning
compressor is automatically turned
off. When the coolant temperature
returns to normal, the A/C operation
automatically resumes. You can
continue to drive your vehicle. If this
message continues to appear, have
the system repaired by your dealer
as soon as possible to avoid
compressor damage.
ENGINE OVERHEATED IDLE

Notice:If you drive your vehicle
while the engine is overheating,
severe engine damage may
occur. If an overheat warning
appears on the instrument panel
cluster and/or DIC, stop the
vehicle as soon as possible. Do
not increase the engine speed
above normal idling speed. See
Engine Overheating on
page 10‑14 for more information.
This message displays when the
engine coolant temperature is too
hot. Stop and allow the vehicle to
idle until it cools down.

Lighting 6-7
Delayed Exit Lighting
This feature illuminates the interior
for a period of time after the key is
removed from the ignition.
The ignition must be off for delayed
exit lighting to work. When the key
is removed, interior illumination
activates and remains on until one
of the following occurs:
.The ignition is in ON/RUN.
.The power door locks are
activated.
.An illumination period of
20 seconds has elapsed.
If during the illumination period a
door is opened, the timed
illumination period will be canceled
and the interior lamps will remain on
because a door is open.
Parade Dimming
Parade mode automatically prohibits
the dimming of the instrument panel
displays during the daylight while
the headlamps are on so that the
displays are still able to be seen.
Battery Load
Management
The vehicle has Electric Power
Management (EPM) that estimates
the battery's temperature and state
of charge. It then adjusts the voltage
for best performance and extended
life of the battery.
When the battery's state of charge
is low, the voltage is raised slightly
to quickly bring the charge back up. When the state of charge is high,
the voltage is lowered slightly to
prevent overcharging. If the vehicle
has a voltmeter gauge or a voltage
display on the Driver Information
Center (DIC), you may see the
voltage move up or down. This is
normal. If there is a problem, an
alert will be displayed.
The battery can be discharged at
idle if the electrical loads are very
high. This is true for all vehicles.
This is because the generator
(alternator) may not be spinning fast
enough at idle to produce all the
power that is needed for very high
electrical loads.
A high electrical load occurs when
several of the following are on, such
as: headlamps, high beams, fog
lamps, rear window defogger,
climate control fan at high speed,
heated seats, engine cooling fans,
trailer loads, and loads plugged into
accessory power outlets.

To change the current mode, select
one of the following:
H(Vent):Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield and side
window outlets. In this mode, the
system automatically selects
outside air.
-(Defog): This mode clears the
windshield of fog or moisture. Air is
directed equally to the windshield
and the floor outlets. When defog is
selected, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is below 4°C
(40°F).
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield with some air to the side window vents and the floor vents.
When defrost is selected, the
system automatically forces outside
air into the vehicle. The air
conditioning compressor will run
automatically in this setting, unless
the outside temperature is below
4°C (40°F).
#(Air Conditioning):
Press to
turn the air conditioning system on
or off. An indicator light comes on to
show that it is on. The air
conditioning can be selected in any
mode as long as the fan is on and
the outside temperature is above
freezing. A flashing indicator light
indicates that the air conditioning
compressor is currently not
available.
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time
it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently. For quick cool down on hot days, do
the following:
1. Select the
Hmode.
2. Press the
#button.
3. Select the coolest temperature for both zones.
4. Select the highest
9speed.
5. When the coolest temperature is selected in the A/C mode, the
system automatically goes into
the recirculation mode to
improve cooling.
Using these settings together for
long periods of time may cause the
air inside the vehicle to become too
dry. To prevent this from happening,
after the air inside the vehicle has
cooled, turn the recirculation
mode off.
The air conditioning system
removes moisture from the air, so a
small amount of water may drip
under the vehicle while idling or
after turning off the engine. This is
normal.

9-6 Driving and Operating
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTires on
page 10‑31.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park the vehicle
and rest. Other driving tips include:
.Keep the vehicle well ventilated.
.Keep the interior
temperature cool.
.Keep your eyes moving
—scan
the road ahead and to the sides.
.Check the rearview mirror and
vehicle instruments often.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips for
driving in these conditions include:
.Keep the vehicle serviced and in
good shape.
.Check all fluid levels and brakes,
tires, cooling system, and
transmission.
.Shift to a lower gear when going
down steep or long hills.
{WARNING
If you do not shift down, the
brakes could get so hot that they
would not work well. You would
then have poor braking or even
none going down a hill. You could
crash. Shift down to let the engine
assist the brakes on a steep
downhill slope.
{WARNING
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. The brakes will have
to do all the work of slowing down
and they could get so hot that
they would not work well. You
would then have poor braking or
even none going down a hill.

Maintenance When Trailer
Towing
The vehicle needs service more
often when pulling a trailer. See the
Maintenance Schedule on
page 11‑3. Things that are
especially important in trailer
operation are automatic
transmission fluid, engine oil, axle
lubricant, belts, cooling system and
brake system. Inspect these before
and during the trip.
Check periodically to see that all
hitch nuts and bolts are tight.
Engine Cooling When Trailer
Towing
The cooling system may temporarily
overheat during severe operating
conditions. SeeEngine Overheating
on page 10‑14.
Trailer Towing
Before pulling a trailer, there are
three important considerations that
have to do with weight:
.The weight of the trailer.
.The weight of the trailer tongue.
.The total weight on your
vehicle's tires.
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
454 kg (1,000 lbs). But even that
can be too heavy.
It depends on how the rig is used.
For example, speed, altitude, road
grades, outside temperature, and
how much the vehicle is used to pull
a trailer are all important. It can
depend on any special equipment
on the vehicle, and the amount of
tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue”
later in this section. Maximum trailer weight is calculated
assuming only the driver is in the
tow vehicle and it has all the
required trailering equipment. The
weight of additional optional
equipment, passengers, and cargo
in the tow vehicle must be
subtracted from the maximum trailer
weight.
Ask your dealer for trailering
information or advice, or write us at
our Customer Assistance Offices.
See
Customer Assistance Offices
on page 13‑3.
Weight of the Trailer Tongue
The tongue load (A) of any trailer is
an important weight to measure
because it affects the total gross
weight of the vehicle. The Gross
Vehicle Weight (GVW) includes the
curb weight of the vehicle, any
cargo carried in it, and the people
who will be riding in the vehicle.
