6. To tighten the belt, push downon the child restraint, pull the
shoulder portion of the belt to
tighten the lap portion of the belt
and feed the shoulder belt back
into the retractor. When installing
a forward-facing child restraint,
it may be helpful to use your
knee to push down on the child
restraint as you tighten the belt. 7. If the child restraint has a top
tether, follow the child restraint
manufacturer's instructions
regarding the use of the top
tether. See Lower Anchors and
Tethers for Children (LATCH
System)
on page 3‑51for more
information.
For H3T models, if the headrest
interferes with the installation of
the child restraint, remove the
headrest by pressing the button
on the headrest post, at the
top of the seatback, and lift to
remove. Store the headrest
under the outboard side of the
rear seat.
8. Push and pull the child restraint in different directions to be sure
it is secure.
To remove the child restraint,
unbuckle the vehicle safety belt and
let it return to the stowed position.
If the top tether is attached to a top
tether anchor, disconnect it. If the
headrest has been removed,
reinsert it onto the seatback.
Securing Child Restraints
(Rear Center Seating
Position)
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of them
will fit there. If the center seat
position is too narrow for the child
restraint, secure it in a rear outside
seat position.
If a child restraint is secured in the
center seat position, follow the
instructions in Securing Child
Restraints (Rear Outboard Seating
Position)
on page 3‑59or Securing
Child Restraints (Rear Center
Seating Position)
on page 3‑61or
Securing Child Restraints (Right
Front Seat Position) on page 3‑62.

Storage 4-3
To adjust a tie-down, pull the locator
pin out and move the tie-down to
another location making sure the
locator pin lines up with a locator
hole on the rail. The tie-down pin
may not be installed correctly if the
pin does not line up, turn it over and
reinstall. The tie-down will not move
when the pin is completely installed.
The maximum load for each rail is
227 kg (500 lbs).
The rails are notched at each end
which allows the tie-downs to be
removed and placed on another rail.
To remove, pull the locator pin out
and slide the tie-down to the end of
the rail and pull back.To remove or install cargo tie-downs
at the front of the bed, slide the
corner cap towards the center of
the bed to expose the rail notches.
To remove the corner cap, pull
either edge away from the rail.
To remove the system, loosen
the toggle bolts on each rail until
they can be removed from the bed
of the truck. To replace the system,
place the toggle bolts and rails
into their original locations and
tighten them to a torque setting
of 17Y
(12.5 ft‐lbs). Notice:
If cargo is tied down
using the horizontal slots on the
top of the pickup box, the box
could be damaged and would
not be covered by the vehicle
warranty. Only use the tie-down
loops if the vehicle does not have
the cargo management system.
Convenience Net
Use the convenience net, located in
the rear, to store small loads as far
forward as possible. The net should
not be used to store heavy loads.

5-2 Instruments and Controls
Controls

wheel to be adjusted.
The tilt lever is on the left side of the
steering column.To tilt, hold the steering wheel and
pull the tilt lever toward you. Raise
or lower the wheel to a comfortable
level, then release the tilt lever to
lock the wheel in place.
Do not adjust the steering wheel
while driving.
Horn
Press near the horn symbols or
press on the steering wheel pad to
sound the horn.
Windshield Wiper/Washer
Turn the band with theNsymbol to
control the windshield wipers.
8 (Mist): Turn to
zfor a single
wipe, then release. For several
wipes, hold the band on
zlonger.
N (Adjustable Interval Wipes):
Turn the band up for more frequent
wipes or down for less frequent
wipes. 6
:Slow wipes, turn the band to
the first solid position past the delay
settings.
1 :Fast wipes, turn the band to
the second solid position past the
delay settings.
9 (Off): Turns the wipers off.
Clear ice and snow from the wiper
blades before using them. If frozen
to the windshield, carefully loosen or
thaw them. If they become worn or
damaged, install new blades or
blade inserts. See Wiper Blade
Replacement on page 10‑32
Windshield wipers work in all power
modes, except when the ignition is
set to LOCK/OFF. After the engine
is turned off, wipers will work in
Retained Accessory Power (RAP)
mode until a door is opened. See
Retained Accessory Power (RAP)
on page 9‑35.

Instruments and Controls 5-13
This light comes on during a
malfunction in one of two ways:
Light Flashing:A misfire condition
has been detected. A misfire
increases vehicle emissions and
could damage the emission control
system on the vehicle. Diagnosis
and service might be required.
The following can prevent more
serious damage to the vehicle:
.Reduce vehicle speed.
.Avoid hard accelerations.
.Avoid steep uphill grades.
.If towing a trailer, reduce the
amount of cargo being hauled as
soon as it is possible.
If the light continues to flash, when
it is safe to do so, stop the vehicle.
Find a safe place to park the
vehicle. Turn the key off, wait at
least 10 seconds, and restart the
engine. If the light is still flashing,
follow the previous steps and see
your dealer for service as soon as
possible. Light On Steady:
An emission
control system malfunction has
been detected on the vehicle.
Diagnosis and service might be
required.
An emission system malfunction
might be corrected.
.Make sure the fuel cap is fully
installed. See Filling the Tankon
page 9‑68. The diagnostic
system can determine if the
fuel cap has been left off or
improperly installed. A loose or
missing fuel cap allows fuel to
evaporate into the atmosphere.
A few driving trips with the cap
properly installed should turn the
light off.
.If the vehicle has been driven
through a deep puddle of water,
the vehicle's electrical system
might be wet. The condition is
usually corrected when the
electrical system dries out.
A few driving trips should turn
the light off.
.Make sure to fuel the vehicle
with quality fuel. Poor fuel quality
causes the engine not to run as
efficiently as designed and may
cause: stalling after start-up,
stalling when the vehicle is
changed into gear, misfiring,
hesitation on acceleration,
or stumbling on acceleration.
These conditions might go away
once the engine is warmed up.
If one or more of these
conditions occurs, change the
fuel brand used. It will require at
least one full tank of the proper
fuel to turn the light off.
See Recommended Fuel
on
page 9‑64.
If none of the above have made
the light turn off, your dealer can
check the vehicle. The dealer
has the proper test equipment
and diagnostic tools to fix any
mechanical or electrical problems
that might have developed.

Instruments and Controls 5-15
If the light comes on while driving,
pull off the road and stop. The brake
pedal might be harder to push, or it
might go closer to the floor. It can
take longer to stop. If the light is
still on, have the vehicle towed for
service. SeeTowing the Vehicle
on
page 10‑90.
{WARNING
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Antilock Brake System
(ABS) Warning Light
For vehicles with the Antilock Brake
System (ABS), this light comes on
briefly when the engine is started.
If it does not, have the vehicle
serviced by your dealer. If the
system is working normally the
indicator light will then go off.
If the ABS light stays on, turn the
ignition off. If the light comes on
while driving, stop as soon as it is
safely possible and turn the ignition
off. Then start the engine again to
reset the system. If the ABS light
stays on, or comes on again while
driving, the vehicle needs service.
If the regular brake system warning
light is not on, the vehicle still has
brakes, but not antilock brakes. If the regular brake system warning
light is also on, the vehicle does not
have antilock brakes and there is a
problem with the regular brakes.
See
Brake System Warning Light
on page 5‑14.
For vehicles with a Driver
Information Center (DIC), see
Brake System Messages
on
page 5‑22for more information.
Up-Shift Light
The vehicle may have an up-shift
light.
When this light comes on, shift to
the next higher gear if weather,
road, and traffic conditions allow.
See Manual Transmission
on
page 9‑44for more information.
