Driving and Operating 9-67Trailer Brakes A loaded trailer that weighs more
than 900 kg (2,000 lbs) needs to
have its own brake system that is
adequate for the weight of the
trailer. Be sure to read and follow
the instructions for the trailer brakes
so they are installed, adjusted and
maintained properly.
Do not tap into the vehicle's
hydraulic system. 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 .

charge the battery.
Electric Brake Control Wiring
Provisions These wiring provisions are
included with the vehicle as part of
the trailer wiring package. These
provisions are for an electric brake
controller. The instrument panel
contains blunt cut wires near the
data link connector for the trailer
brake controller. The harness
contains the following wires: .
Dark Blue: Brake Signal to

It should be installed by your dealer
or a qualified service center. Tow/Haul Mode
Pressing this button at the end of
the shift lever turns on and off the
tow/haul mode.
This indicator light on the instrument
panel cluster comes on when the
tow/haul mode is on.
Tow/Haul is a feature that assists
when pulling a heavy trailer or a
large or heavy load. See Tow/Haul
Mode on page 9 ‑ 33 for more
information. Tow/Haul is designed to be most
effective when the vehicle and
trailer combined weight is at least
75 percent of the vehicle's Gross
Combined Weight Rating (GCWR).
See “ Weight of the Trailer ” in Trailer
Towing on page 9 ‑ 61 . Tow/Haul is
most useful under the following
driving conditions: .
When pulling a heavy trailer or a
large or heavy load through
rolling terrain. .
When pulling a heavy trailer or a
large or heavy load in stop and
go traffic. .
When pulling a heavy trailer or a
large or heavy load in busy
parking lots where improved low
speed control of the vehicle is
desired.

Driving and Operating 9-69Operating the vehicle in Tow/Haul
when lightly loaded or with no trailer
at all will not cause damage.
However, there is no benefit to the
selection of Tow/Haul when the
vehicle is unloaded. Such a
selection when unloaded may result
in unpleasant engine and
transmission driving characteristics
and reduced fuel economy. Tow/
Haul is recommended only when
pulling a heavy trailer or a large or
heavy load. Trailer Sway
Control (TSC) Non-hybrid vehicles with StabiliTrak
have a Trailer Sway Control (TSC)
feature. If the vehicle is towing a
trailer and the system detects that
the trailer is swaying, the vehicle
brakes are applied without the driver
pressing the brake pedal. The TCS/
StabiliTrak warning light will flash on
the instrument panel cluster to notify
the driver to reduce speed. If the
trailer continues to sway, StabiliTrak
will reduce engine torque to help
slow the vehicle. See StabiliTrak ®
System on page 9 ‑ 37 for more
information.
Adding non ‐ dealer accessories can
affect the vehicle performance. See
Accessories and Modifications on
page 10 ‑ 3 for more information.Conversions and

2. Flip the handle up and then pull
out the dipstick and wipe it with
a clean rag or paper towel.
3. Install the dipstick by pushing it
back in all the way, wait
three seconds, and then pull it
back out again.
4. Check both sides of the dipstick
and read the lower level. Repeat
the check procedure to verify the
reading.
5. Safe operating level is within the
HOT cross hatch band on the
dipstick. If the fluid level is not
within the HOT band, and the
transmission temperature is
between 71°C and 93°C (160°F and 200°F), add or drain fluid as
necessary to bring the level into
the HOT band. If the fluid level is
low, add only enough fluid to
bring the level into the HOT
band. It does not take much
fluid, generally less than 0.5 L
(1 pint). Do not overfill.
6. If the fluid level is in the
acceptable range, push the
dipstick back in all the way, then
flip the handle down to lock the
dipstick in place.
Consistency of Readings Always check the fluid level at least
twice using the procedures
described. Consistency (repeatable
readings) is important to maintaining
proper fluid level. If fluid is added, it
may take 15 minutes or longer to
obtain an accurate reading because
of residual fluid draining down the
dipstick tube. If inconsistent
readings persist, check the
transmission breather to be sure it is clean and not clogged. If readings
are still inconsistent, contact your
dealer.
Engine Air Cleaner/Filter See Engine Compartment Overview
on page 10 ‑ 6 for the location of the
engine air cleaner/filter.
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mile)
interval. See Maintenance Schedule
on page 11 ‑ 3 for more information.
If driving on dusty/dirty conditions,
inspect the filter at each engine oil
change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the engine air cleaner/filter
from the vehicle by following
Steps 1 through 6. When the engine
air cleaner/filter is removed, lightly
shake it to release loose dust and
dirt. If the engine air cleaner/filter

10-24 Vehicle Care Notice .
When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water. .
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. .
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. .
Do not use engine coolant
(antifreeze) in the windshield
washer. It can damage the
windshield washer system
and paint. Brakes This vehicle has disc brakes. Disc
brake pads have built-in wear
indicators that make a high-pitched
warning sound when the brake pads
are worn and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{ WARNINGThe brake wear warning sound
means that soon the brakes will
not work well. That could lead to
a crash. When the brake wear
warning sound is heard, have the
vehicle serviced.
Notice: Continuing to drive with
worn-out brake pads could result
in costly brake repair. Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. 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 pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in Capacities and
Specifications on page 12 ‑ 2 .
Brake linings should always be
replaced as complete axle sets.
Brake Pedal Travel See your dealer if the brake pedal
does not return to normal height,
or if there is a rapid increase in
pedal travel. This could be a sign
that brake service might be
required.
Brake Adjustment
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.

Vehicle Care 10-25Replacing Brake System Parts The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake
parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might
not work properly. For example,
installing disc brake pads that are
wrong for the vehicle, can change
the balance between the front and
rear brakes — for the worse. The
braking performance expected can
change in many other ways if the
wrong replacement brake parts are
installed. Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid. See
Engine Compartment Overview on
page 10 ‑ 6 for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down: .
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up. .
A fluid leak in the brake
hydraulic system can also cause
a low fluid level. Have the brake
hydraulic system fixed, since a
leak means that sooner or later
the brakes will not work well. Do not top off the brake fluid.
Adding fluid does not correct a leak.
If fluid is added when the linings are
worn, there will be too much fluid
when new brake linings are
installed. Add or remove brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
{ WARNINGIf too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.
Add brake fluid only when work is
done on the brake hydraulic
system. See “ Checking Brake
Fluid ” in this section.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5 ‑ 19 .

4. Replace the wiper blade.
5. Return the wiper blade assembly
to the park rest position.
Glass Replacement If the windshield or front side glass
must be replaced, see your dealer
to determine the correct
replacement glass. Headlamp Aiming The vehicle has a visual optical
headlamp aiming system. The aim
of the headlamps have been preset
at the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the aim of the headlamps
may be affected and adjustment
may be necessary.
If oncoming vehicles flash their high
beams at you, this may mean the
vertical aim of the headlamps needs
to be adjusted.
It is recommended that the vehicle
is taken to your dealer for service if
the headlamps need to be adjusted.
It is possible however, to re-aim the
headlamps as described. The vehicle should: .
Be placed so the headlamps are
7.6 m (25 ft.) from a light colored
wall or other flat surface. .
Have all four tires on a level
surface which is level all the way
to the wall or other flat surface. .
Be placed so it is perpendicular
to the wall or other flat surface. .
Not have any snow, ice, or mud
on it. .
Be fully assembled and all other
work stopped while headlamp
aiming is being performed. .
Be normally loaded with a full
tank of fuel and one person or
75 kg (160 lbs) sitting on the
driver seat. .
Have the tires properly inflated. .
Have the spare tire is in its
proper location in the vehicle.
