Damaged Tires
{Danger
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. 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). Wheel size is also stamped
on the side of each wheel.
To help avoid personal injury and
property damage if a wheel must
be changed, seek expert tire
services if you can. If you must
remove the wheel without any
such help, do the following:(Continued)
Danger (Continued)
.If the tire looks as if it may
be underinflated, stand to
the side and check whether
the wheel assembly
appears normal by
comparing it to another
wheel assembly on the
vehicle.
. Let the air out of the tire by
taking out the valve core.
If you have a way to put air
back in a tire, note that it is
good safety practice to let
the air out of both tires of a
dual assembly before taking
off the damaged tire and rim
assembly from the vehicle.
After letting out the air, take
off the tire and rim assembly
and install a spare tire and
rim assembly.
If your vehicle is equipped
with a differential lock
system or limited slip
differential (LSD), it might
(Continued)
Danger (Continued)
start moving when the
engine power is transmitted
to the rear axle even when
one of the wheels on the
axle is raised clear of the
ground. Do not start the
engine with any rear wheel
in contact with the ground.
If you are not fully
experienced on the
procedures to follow, and/or
are not equipped with the
proper tools and equipment,
again, do not attempt to
raise the vehicle, or remove
or install the tire and wheel
assembly—seek expert tire
services.
. Do not put air back in a tire
that has been run flat, or is
seriously low on air, without
first having the tire taken off
the wheel and the tire
checked for damage.

{Warning
For safety and the protection of
the vehicle, do not push-start the
vehicle.
Never tow the vehicle to start
because a surge forward when
the engine starts could cause a
collision with the tow vehicle.
Also, this vehicle has a 12-volt
battery, 12-volt starting system
and a negative ground electrical
system; be sure the vehicle or
equipment used to jump start your
engine is also 12-volt. Use of any
other system may damage the
vehicle's electrical components.
Under no circumstances should
the battery's positive and negative
terminals be put in contact with
one another.
When connecting the cables,
under no circumstances should
the clips be allowed to touch each
other.(Continued)
Warning (Continued)
Do not disconnect a battery
terminal with the engine running.
It could cause a breakdown in the
electrical system.
You and others could be seriously
injured.
If you notice battery fluid leaking,
have an inspection carried out
immediately by the nearest dealer.
Diesel engine vehicles have more
than one battery because of the
higher torque required to start a
diesel engine. This procedure can
be used to start a single-battery
vehicle from any of the diesel
vehicle's batteries. However, at low
temperatures, it may not be possible
to start a diesel engine from a single
battery from another vehicle. 1. Use a vehicle that has a charged battery with the same
voltage. Make sure that the
other vehicle also has a 12-volt
starting system, and that it is the negative (–) terminal which
is grounded (attached to the
engine block, or frame rail).
2. Position the vehicle with the good (charged) battery so that
the booster (jumper) cables will
reach. But never let the
vehicles touch. Also, be sure
the booster cables to be used
do not have loose or missing
insulation.
3. In both vehicles, turn off the ignition (engine control) switch
and all lights and accessories
except the hazard flasher or
any lights needed for the work
area. In both vehicles, apply
the parking brake firmly and
move the selector lever to the
"P" position.
