A WARNING
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than your vehicle was designed
to carry will prevent the ve­
hicle from handling properly
and increase the risk of a loss of vehicle control.
-The brakes on a vehicle that has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly causing loss of
control and a crash.
-Always make sure that the
total load being transported
- including the weight of a
trailer hitch and the tongue
weight of a loaded trailer -
does not make the vehicle heavier than the vehicle's Gross Vehicle Weight Rat­
ing.
A WARNING -
-Incorrect tire pressures
and/or underinflation can
lead to a ser ious or fatal ac­
cident .
-Incorrect tire pressures and/or underinflation cause increased tire wear and can
affect the handling of the
vehicle.
-Incorrect tire pressures and/or underinflation can
also lead to sudden tire fail­
ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the
tires originally installed on
your vehicle is listed on the tire
pressure label located on driv­
er's side 8-pillar.
The recommended tire pres­
sures are on the tire pressure
label and in the table
c;, page 2 78, Cold tire inflation
pressure.This
means that the
pressure must be checked and
adjusted when the tire has not .,.

288 Tires and whee ls
- The brakes on a vehicle that
has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has been overloaded can fail
suddenly, including a blow­
out and sudden deflation,
causing loss of control and a
crash.
-Always make sure that the total load being transported
- including the weight of a
trailer hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
Determining correct load
limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining Correct Load Limit
1 . Locate the statement "THE
COMBINED WEIGH T OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
~ page 2 78,
fig . 250 .
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle .
3 . Subtract the combined
weight of the driver and pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
~ page 278, fig. 250.
4. The resulting figure equals
the available amount of car­go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs .
and there will be five 150 lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs. (1400 -750
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo .,..
