318 Vehicle Care
Using worn-out tires is dangerous
because they might have an
increased chance of getting
punctured or bursting while driving.
Check all tires to see if tread wear
indicators appear on their treads
and also check their entire tread for
its depth with a depth gauge to
make sure that the grooves are
deeper than the specified depth.
A tire with tread wear indicators
appearing must be changed. Also,
check the tires for uneven or
otherwise abnormal wear.
{Warning
Tires with excessively shallow
tread grooves will increase the
chance of skidding and, when
driving at high speeds,
hydroplaning. You and others
could be seriously injured.
Hydroplaning occurs when a vehicle
is running at high speeds on a wet
road and a layer of water forms
between the road surface and tires
causing the tires to float on it.
Hydroplaning prevents the driver from steering correctly and from
slowing down the vehicle with the
brake pedal.
Use of Low Aspect Ratio Tires
1. Standard tire
2. Low aspect ratio tire
Low aspect ratio tires for truck
applications (aspect ratio at 70%)
have an air volume 20% to 30%
smaller than that of standard tires.
When air begins to leak, therefore,
low aspect ratio tires adversely
affect vehicle operation much faster
than standard tires. Check air
pressure of low aspect ratio tires
more often than standard tires using
a tire air pressure gauge.
Damaged Tires
{Warning
It is dangerous to mount the
wrong size tire on a wheel. If you
do so, the tire/wheel can explode
as air is being added. This
explosion may result in severe
personal injury or death. For the
3.0L diesel engine, to learn which
wheels and tires are correct, look
at the "VIN and Weight Rating
Plate" on the left side rear pillar
panel below the striker. For the
5.2L diesel engine, to learn which
wheels and tires are correct, look
at the "VIN, Weight Rating, and
Greenhouse Gas (GHG)
Emissions Plate" on the left side
rear pillar panel below the striker
(single cab) or on the left center
pillar panel beside the shoulder
seat belt anchor (crew cab).For

334 Vehicle Care
Apply the parking brake before
disconnecting from the towing
vehicle. Check and fill rear axle with
oil, if required.
Rear End Towing
When towing a vehicle with rear
wheels raised, secure the steering
wheel to maintain straight-ahead
position. Make certain that the front
axle is not loaded beyond the front
axle gross axle weight rating
(GAWR) as indicated on the
vehicle's VIN and weight rating plate
(diesel) or the vehicle's "Vehicle
Certification and Greenhouse Gas
(GHG) Emissions Plate" (gasoline).
Special Towing Instructions1. All state and local laws regarding such items as
warning signals, night
illumination, speed, etc., must
be followed.
2. Safety chains must be used.
3. No vehicle should ever be towed over 88 km/h (55 mph). 4. Loose or protruding parts of
damaged vehicles should be
secured prior to moving.
5. A safety chain system completely independent of the
primary lifting and towing
attachment must be used.
6. Operators should refrain from going under a vehicle which is
being lifted by the towing
equipment unless the vehicle is
adequately supported by safety
stands.
7. No towing operation which for any reason jeopardizes the
safety of the wrecker operator
or any bystanders or other
motorists should be attempted.Appearance Care
Exterior Care
Exterior Finish
The paint finish on your vehicle
provides beauty, depth of color,
gloss retention and durability.
While cleaning the vehicle, do not
grip the roof marker lights to prevent
damage or water leakage.
Washing
The best way to preserve your
vehicle's finish is to keep it clean by
washing it often.
Wash the vehicle in lukewarm or
cold water. Do not use hot water or
wash your vehicle in the direct rays
of the sun. Do not use strong soap
or chemical detergents. All cleaning
agents should be flushed promptly
from the surface and not allowed to
dry on the finish.
These vehicles are designed to
operate under normal environmental
conditions to withstand natural
elements. However, unusual

Number (VIN)
The VIN and engine number are
necessary for registering your
vehicle. They are also necessary
when your vehicle undergoes official
inspections. Provide your dealer
with these numbers when you are
having the vehicle repaired or when
ordering replacement parts. The
Dealer will be able to do the
requested jobs more competently
and quickly.

384 Technical Data
The "Vehicle Certification and
Greenhouse Gas (GHG) Emissions
Plate" shows the manufacturer's
gross vehicle weight rating (GVWR),
the front and rear gross axle weightratings (GAWRs), as well as the VIN
and emissions information for your
vehicle.
This plate is located on the left side
rear pillar panel below the striker
(single cab) or on the left center
pillar panel beside the shoulder seat
belt anchor (crew cab).
The VIN is a legal identifier of your
vehicle. It not only appears on the
VIN plate; but also on the vehicle
certificates of title and registration.
The VIN specifically identifies a
vehicle by code.
See
“Overloading” underInformation
on Loading the Vehicle 064.
The VIN contains multiple pieces of
information including the vehicle
and engine model codes as shown
below.
