Trailer Wiring Harness Heavy-Duty Trailer Wiring Harness Package
The vehicle has a seven-pin universal heavy-duty trailer
connector attached to the rear bumper beam next to the
integrated trailer hitch. The seven-wire harness contains the following trailer
circuits: .
Yellow: Left Stop/Turn Signal .
Dark Green: Right Stop/Turn Signal .
Brown: Taillamps .
White: Ground .
Light Green: Back-up Lamps .
Red: Battery Feed* .
Dark Blue: Trailer Brake*
*The fuses for these two circuits are installed in the
underhood electrical center, but the wires are not
connected. They should be connected by your dealer or
a qualified service center.
If charging a remote (non-vehicle) battery, press the
tow/haul mode button located at the end of the shift
lever. 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 as a second way
to boost the vehicle system and charge the battery.

Doing Your Own Service Work If this vehicle is a Two ‐ mode Hybrid, see the Two ‐ mode
Hybrid manual for more information.
{ WARNING: You can be injured and the vehicle could be
damaged if you try to do service work on a vehicle
without knowing enough about it. .
Be sure you have sufficient knowledge,
experience, the proper replacement parts,
and tools before attempting any vehicle
maintenance task. .
Be sure to use the proper nuts, bolts, and
other fasteners. English and metric fasteners
can be easily confused. If the wrong fasteners
are used, parts can later break or fall off. You
could be hurt. If doing some of your own service work, use the proper
service manual. It tells you much more about how to
service the vehicle than this manual can. To order the
proper service manual, see Service Publications
Ordering Information on page 9 ‑ 18 .
This vehicle has an airbag system. Before attempting to
do your own service work, see Servicing Your
Airbag-Equipped Vehicle on page 2 ‑ 89 .
Keep a record with all parts receipts and list the mileage
and the date of any service work performed. See
Maintenance Record on page 8 ‑ 14 .
Adding Equipment to the Outside of
the Vehicle Things added to the outside of the vehicle can affect the
airflow around it. This can cause wind noise and can
affect fuel economy and windshield washer
performance. Check with your dealer before adding
equipment to the outside of the vehicle.

Engine Oil Checking Engine Oil It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 7 ‑ 16 for the
location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If this is not done, the
oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

Model designation .
Paint information .
Production options and special equipment
Do not remove this label from the vehicle. Electrical System Add-On Electrical Equipment Notice: Do not add anything electrical to the vehicle
unless you check with your dealer first. Some
electrical equipment can damage the vehicle and
the damage would not be covered by the vehicle's
warranty. Some add-on electrical equipment can
keep other components from working as they
should.
Add-on equipment can drain the vehicle 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
Your Airbag-Equipped Vehicle on page 2 ‑ 89 and

Windshield Wiper Fuses The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.

Power Windows and Other Power
Options Circuit breakers protect the power windows and other
power accessories. If the current load is too heavy, the
circuit breaker opens and then closes after a cool down
period, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers If the vehicle is a Two-mode Hybrid, see the Two-mode
Hybrid manual for more information.
The wiring circuits in the vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating. If you ever have a problem on the road and don't
have a spare fuse, you can borrow one that has the
same amperage. Just pick some feature of your vehicle
that you can get along without – like the radio or
cigarette lighter – and use its fuse, if it is the
correct amperage. Replace it as soon as you can.
Instrument Panel Fuse Block The instrument panel fuse
block access door is
located on the driver side
edge of the instrument
panel.
Pull off the cover to access the fuse block.
