uuBefore Driving uCarrying Cargo
Driving
Carrying Cargo
Your vehicle can carry a large amount of cargo in the pickup bed.
However, the pickup bed is not in tended for carrying passengers.
People who ride in the pickup bed can be ve ry seriously injured or killed in a crash.
• When loading and unloading cargo, make sure all passengers or any objects are
clear of the tailgate before opening or cl osing it. The tailgate should be closed
securely before driving when it is not used as the extended pickup bed.
• The maximum allowable loading weight for the trunk is 300 lbs (136 kg).
Do not exceed this weight limi t, or you may damage the trunk.
• The maximum allowable loading weight on the pickup bed is 1,100 lbs (500 kg).
Do not exceed the load limit.
2 Maximum Load Limit P. 415
•Distribute cargo evenly on the pickup bed. Place the heaviest items on the bottom
and as far forward as possible of the rear axle. Tie down and secure all items that
could be thrown out of the vehicle during a crash or sudden stop.
• If you stack items higher than the bed si des, tailgate, or back window, secure
them with a net or cover.
This will reduce the risk of items being thrown out of the pickup bed during a
crash or sudden stop.
• When the tailgate is dropped open, it ca n be used as an extended pickup bed.
The maximum allowable weight on the tailgate while driving is 300 lbs (136 kg).
Exceeding this limit could damage the tailgate.
• Carrying heavy cargo in the pickup bed will raise your vehicle’s center of gravity.
This can affect handling and performance. Drive more slowly and cautiously, and
allow extra time and distance for braking.
■Carrying Cargo in the Pickup Bed1Carrying Cargo
3WARNING
Allowing passengers to ride in the pickup
bed or on the tailgate can result in death or
serious injury in a crash.
Make sure all passengers ride in a seat and
wear a seat belt properly.
3WARNING
Never let passengers ride in the pickup bed,
in the trunk space, or on the bed rails. This
could cause very serious injuries or death.
No one should ride in any position on your
vehicle that is not eq uipped with seats and
seat belts.
Exceeding load limits or improperly loading
cargo on the vehicle can cause a crash in
which you can be seriously injured or killed.

Driving
Driving Safely with a Trailer
• Have the trailer properly serviced and keep it in good condition.
• Make sure that all the weights and load in the vehicle and trailer are within limits.
2Towing Load Limits P. 420
•Securely attach the hitch, safety chains, and other necessary parts to the trailer.
• Securely store all the items in and on the trailer so that they do not shift while
driving.
• Check if the lights and brakes on the trailer are working properly.
• Check the pressures of the traile r tires, including the spare.
• Drive slower than normal.
• Obey posted speed limits for vehicles with trailers.
• Use the
(D position when towing a trailer on level roads.
• Turn more slowly and with a wider turning arc than normal.
• Allow more time and distance for braking.
• Do not brake or turn suddenly.
■Things You Need To Know Before Towing a Trailer
■Towing Speeds and Gears
■Turning and Braking
1Driving Safely with a Trailer
Operating speed when towing a trailer must not
exceed 62 mph (100 km/h).
Parking
In addition to the normal precautions, place wheel
chocks at each of the trailer’s tires.
When towing a trailer, we recommend that you carry
a full-size spare wheel and tire for both your vehicle
and trailer. If you use the compact spare tire that
came with your vehicle, it could adversely affect
vehicle handling.
Remember to unhitch the tra iler before changing a
flat tire. Ask the trailer sales or rental agency where
and how to store the trailer’s spare tire.
1 Towing Speeds and Gears
When towing a fixed-sided trailer (e.g., camper), do
not exceed 55 mph (88 km/h).
At higher speeds, the trai ler may sway or affect
vehicle handling.
