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.
Weight of the Trailer Tongue
The tongue load (1) 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. If there are a lot of options,
equipment, passengers, or cargo in the
vehicle, it will reduce the tongue
weight the vehicle can carry, which
will also reduce the trailer weight the
vehicle can tow. If towing a trailer, the
tongue load must be added to the GVW because the vehicle will be
carrying that weight, too. See
Vehicle
Load Limits 0173.The trailer tongue (1) should weigh 10
to 15 percent of the total loaded
trailer weight (2).
After loading the trailer, weigh the
trailer and then the tongue,
separately, to see if the weights are
proper. If they are not, adjustments
might be made by moving some items
around in the trailer.
Total Weight on Your Vehicle's
Tires
Be sure the vehicle's tires are inflated
to the upper limit for cold tires. These
numbers can be found on the Tire and
Loading Information label. See Vehicle
Load Limits 0173. Make sure not to go
over the GVW limit for the vehicle,
including the weight of the trailer
tongue.
Towing Equipment
Hitches
Use the correct hitch equipment. See
your dealer or a hitch dealer for
assistance.
. The rear bumper on the vehicle is
not intended for hitches. Do not
attach rental hitches or other
bumper-type hitches to it. Use
only a frame-mounted hitch that
does not attach to the bumper.
. Will any holes be made in the
body of the vehicle when the
trailer hitch is installed? If so, seal
the holes when the hitch is
removed. If the holes are not
sealed, dirt, water, and deadly

carbon monoxide (CO) from the
exhaust can get into the vehicle.
SeeEngine Exhaust 0182.
Safety Chains
Always attach chains between the
vehicle and the trailer. Cross the safety
chains under the tongue of the trailer
to help prevent the tongue from
contacting the road if it becomes
separated from the hitch. Leave
enough slack so the rig can turn.
Never allow safety chains to drag on
the ground.
Trailer Brakes
Does the trailer have its own brakes?
Be sure to read and follow the
instructions for the trailer brakes so
they are installed, adjusted, and
maintained properly.
Because the vehicle has antilock
brakes, do not tap into the vehicle's
brake system. If this is done, both
brake systems will not work well or
at all.
Conversions and
Add-Ons
Add-On Electrical
Equipment
{Warning
The Data Link Connector (DLC) is
used for vehicle service and
Emission Inspection/Maintenance
testing. See Malfunction Indicator
Lamp (Check Engine Light) 0120.
A device connected to the DLC —
such as an aftermarket fleet or
driver-behavior tracking device —
may interfere with vehicle systems.
This could affect vehicle operation
and cause a crash. Such devices
may also access information stored
in the vehicle’s systems.
Caution
Some electrical equipment can
damage the vehicle or cause
components to not work and would
not be covered by the vehicle
warranty. Always check with your
dealer before adding electrical
equipment.
Add-on equipment can drain the
vehicle's 12-volt battery, even if the
vehicle is not operating.
The vehicle has an airbag system.
Before attempting to add anything
electrical to the vehicle, see Servicing
the Airbag-Equipped Vehicle 079
and Adding Equipment to the
Airbag-Equipped Vehicle 079.

2. Fill the CAC bottle with theproper mixture to the COLD FILL
mark pointed to on the front of
the CAC bottle.
3. Replace the pressure cap tightly.
Engine Overheating
The vehicle has an engine coolant
temperature gauge and an engine
temperature light to warn of engine
overheating.
There are also engine hot messages
that may be displayed in the Driver
Information Center (DIC). See Engine
Cooling System Messages 0136.
If the decision is made not to lift the
hood when one of these warnings
appears, but get service help
right away.
If the decision is made 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, the fans should be
running. If they are not, do not
continue to run the engine and have
the vehicle serviced.
Caution
Running the engine without coolant
may cause damage or a fire. Vehicle
damage would not be covered by
the vehicle warranty. See Overheated
Engine Protection Operating Mode
0 238 for information on driving to
a safe place in an emergency.
If Steam Is Coming from the
Engine Compartment
{Warning
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. Just 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.
(Continued)
Warning (Continued)
If you keep driving when the engine
is overheated, the liquids in it can
catch fire. You or others could be
badly burned. Stop the engine if it
overheats, and get out of the
vehicle until the engine is cool.
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 highesttemperature and to the highest
fan speed. Open the windows as
necessary.
3. When it is safe to do so, pull off the road, shift to P (Park) or
N (Neutral), and let the
engine idle.
If the temperature overheat gauge is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue to
drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back on,
continue to drive normally and have
the cooling system checked for proper
fill and function.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while parked.
If the warning is still displayed, turn
off the engine until it cools down.
Also, see “Overheated Engine
Protection Operating Mode ”next in
this section.Overheated Engine
Protection Operating Mode
This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency situation.
If an overheated engine condition
exists, an overheat protection mode,
which alternates firing groups of
cylinders, helps prevent engine
damage. In this mode, there is
significant loss in power and engine
performance.
The engine coolant temperature
warning light comes on in the
instrument cluster, to indicate the
vehicle has entered overheated engine
protection operating mode. The
temperature gauge also indicates an
overheat condition exists. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.
Power Steering Fluid
The power steering fluid reservoir is
under the engine cover on the
passenger side toward the rear of the
engine compartment. See Engine
Compartment Overview 0224.
When to Check Power Steering
Fluid
It is not necessary to regularly check
power steering fluid unless you
suspect there is a leak in the system
or an unusual noise is heard. A fluid
loss in this system could indicate a
problem. Have the system inspected
and repaired.
How to Check Power Steering
Fluid
Check the level when the engine
is cool.
