& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident , serious personal injury , and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehi cle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly ,
including a blowout 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 Rating .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport 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
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label)=>
page 321 , fig. 247.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3 . Subtract the combined weight of the
driver and passengers from
"XXX" kilo ­
grams or
"XXX" pounds shown on the
sticker=>
page 321 , fig. 247.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the
" XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 -750 (5
X 150) = 650 lbs.) t,,,

5. Determine the combined weight of
luggage and cargo being loaded on th e
vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determin e how this reduces the avail ­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidew all (~
page 329,
fig . 251) to determine the designated
load rating for a specific tire . •
