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)0129. 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 080.

5. Turn off the airconditioning.
6. Set the parking brake.
7. At the same time, press the accelerator and the
brake for automatic
transmission vehicles for
two seconds, then release.
At the end of the cycle, check
the coolant level in the surge
tank and add coolant, if it is
low. Turn off the vehicle, allow
the Engine Control Module
(ECM) to go to sleep, about
two minutes, and repeat
steps 3-7.
Listen for pump activation and
movement of the control
valves while watching the level
of the tank. If the tank
empties, turn the ignition off,
carefully remove the surge
tank cap, refill to the indicated
mark and repeat steps 3-6.
The fill and air removal
process will run for
approximately 10 minutes.Engine Overheating
The vehicle has several
indicators to warn of the
engine overheating.
There is an engine coolant
temperature gauge on the
instrument cluster. See Engine
Coolant Temperature Gauge
0 126. The vehicle may also
display a message on the
Driver Information
Center (DIC).
If the decision is made not to
lift the hood when this
warning appears, get service
help right away. See Roadside
Assistance Program 0446.
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 fan is
running. If the engine is
overheating, the fan should be
running. If it is not, do not
continue to run the engine.
Have the vehicle serviced.
Caution
Do not run the engine if
there is a leak in the engine
cooling system. This can
cause a loss of all coolant
and can damage the system
and vehicle. Have any leaks
fixed right away.
If Steam Is Coming from
the Engine Compartment
{Warning
Steam and scalding liquids
from a hot cooling system
are under pressure. Turning
the pressure cap, even a
little, can cause them to
come out at high speed and
you could be burned. Never
turn the cap when the
cooling system, including the
pressure cap, is hot. Wait for
the cooling system and
pressure cap to cool.

until the tank is full. See
Engine Compartment
Overview0342 for reservoir
location.
Caution
.Do not use washer fluid
that contains any type of
water repellent coating.
This can cause the wiper
blades to chatter or skip.
.Do not use engine coolant
(antifreeze) in the
windshield washer. It can
damage the windshield
washer system and paint.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the
solution to freeze and
damage the washer fluid
tank and other parts of
the washer system.
.When using concentrated
washer fluid, follow the
manufacturer instructions
for adding water.
(Continued)
Caution (Continued)
.Fill the washer fluid tank
only three-quarters full
when it is very cold. This
allows for fluid expansion
if freezing occurs, which
could damage the tank if it
is completely full.
Brakes
Disc brake linings have built-in
wear indicators that make a
high-pitched warning sound
when the brake linings are
worn and new linings are
needed. The sound can come
and go or can be heard all the
time when the vehicle is
moving, except when applying
the brake pedal firmly.
{Warning
The brake wear warning
sound means that soon the
brakes will not work well.
That could lead to a crash.
(Continued)
Warning (Continued)
When the brake wear
warning sound is heard,
have the vehicle serviced.
Caution
Continuing to drive with
worn-out brake linings could
result in costly brake repairs.
Some driving conditions or
climates can cause a brake
squeal when the brakes are
first applied, clearing up
following several applications.
This does not mean something
is wrong with the brakes.
Properly torqued wheel nuts
are necessary to help prevent
brake pulsation. When tires
are rotated, inspect brake
linings for wear and evenly
tighten wheel nuts in the
proper sequence to torque
specifications. See Capacities
and Specifications 0438.

Step 7.
9. Proceed to the passenger side rear tire, and repeat
Step 7.
10. Proceed to the driver side rear tire, and repeat
Step 7. The horn sounds
two times to indicate the
sensor identification code
has been matched to the
driver side rear tire, and
the TPMS sensor matching
process is no longer active.
The TIRE LEARNING ACTIVE message on the
DIC display screen
goes off.
11. Turn the vehicle off.
12. Set all four tires to the recommended air pressure
level as indicated on the

Tire Inspection
We recommend that the
tires, including the spare
tire, if the vehicle has one,
be inspected for signs of
wear or damage at least
once a month.
Replace the tire if:
.The indicators at three or
more places around the
tire can be seen.
.There is cord or fabric
showing through the
tire's rubber.
