Safety chains
You should always attach chains between
your vehicle and your trailer.
Instructions about safety chains may
be provided by the hitch manufacturer
or trailer manufacturer. Follow the
manufacturer’s recommendation for
attaching safety chains. Always leave just
enough slack so you can turn with your
trailer. And, never allow safety chains to
drag on the ground.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to
your country’s regulations and that
it is properly installed and operating
correctly.
If your trailer weighs more than the
maximum trailer weight without trailer
brakes loaded, then it needs its own
brakes and they must be adequate. Be
sure to read and follow the instructions
for the trailer brakes so you’ll be able
to install, adjust and maintain them
properly. Be sure not to modify your
vehicle’s brake system.
WARNING
Do not use a trailer with its own brakes
unless you are absolutely certain that
you have properly set up the brake
system. This is not a task for amateurs.
Use an experienced, competent trailer
shop for this work.
Driving with a Trailer
Towing a trailer requires a certain
amount of experience. Before setting
out for the open road, you must get to
know your trailer. Acquaint yourself with
the feel of handling and braking with the
added weight of the trailer. And always
keep in mind that the vehicle you are
driving is now longer and not nearly as
responsive as your vehicle is by itself.
Before you start, check the trailer hitch
and platform, safety chains, electrical
connector(s), lights, tires and brakes.
During your trip, occasionally check
to be sure that the load is secure, and
that the lights and trailer brakes are still
working.
Distance
Stay at least twice as far behind the
vehicle ahead as you would when driving
your vehicle without a trailer. This can
help you avoid situations that require
heavy braking and sudden turns.
Passing
You will need more passing distance up
ahead when you’re towing a trailer. And,
because of the increased vehicle length,
you’ll need to go much farther beyond
the passed vehicle before you can return
to your lane.

Certification label
OBH059070
The certification label is located on the
driver's door sill at the center pillar and
shows the maximum allowable weight of
the fully loaded vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The
GVWR includes the weight of the vehicle,
all occupants, fuel and cargo.
This label also tells you the maximum
weight that can be supported by the
front and rear axles, called Gross Axle
Weight Rating (GAWR).
The total weight of the vehicle, including
all occupants, accessories, cargo, and
trailer tongue load must not exceed the
Gross Vehicle Weight Rating (GVWR) or
the Gross Axle Weight Rating (GAWR).
To find out the actual loads on your front
and rear axles, you need to go to a weigh
station and weigh your vehicle. Be sure
to spread out your load equally on both
sides of the centerline.
WARNING
Overloading

[ Never exceed the GVWR for your
vehicle, the GAWR for either the front
or rear axle and vehicle capacity
weight. Exceeding these ratings
can affect your vehicle's handling
and braking ability, and cause an
accident.

[ Do not overload your vehicle.
Overloading your vehicle can cause
heat buildup in your vehicle's tires
and possible tire failure, increased
stopping distances and poor vehicle
handling-all of which may result in a
crash.
NOTICE
Overloading your vehicle may cause
damage. Repairs would not be covered
by your warranty. Do not overload your
vehicle.
WARNING
If you carry items inside your vehicle
(for example, suitcases, tools, packages,
or anything else), they are moving as
fast as the vehicle. If you have to stop
or turn quickly, or if there is a crash, the
items will keep going and can cause
an injury if they strike the driver or a
passenger.

[Put items in the cargo area of your
vehicle. Try to spread the weight
evenly.

[ Do not stack items like suitcases
inside the vehicle above the tops of
the seats.

[ Do not leave an unsecured child
restraint in your vehicle.

[ When you carry something inside the
vehicle, secure it.

• The driver has the responsibility to
control the vehicle. Do not solely
depend on Forward Collision-
Avoidance Assist. Rather, maintain
a safe braking distance, and, if
necessary, depress the brake pedal
to reduce driving speed or to stop
the vehicle.
• Never deliberately operate Forward
Collision-Avoidance Assist on people,
objects, etc. It may cause serious
injury or death.
• Forward Collision-Avoidance
Assist may not operate if the driver
depresses the brake pedal to avoid
collision.
• Depending on the road and driving
conditions, Forward Collision-
Avoidance Assist may warn the driver
late or may not warn the driver.
• During Forward Collision-Avoidance
Assist operation, the vehicle may
stop suddenly injuring passengers
and shifting loose objects. Always
have the seat belt on and keep loose
objects secured.
• If any other system’s warning
message is displayed or audible
warning is generated, Forward
Collision-Avoidance Assist warning
message may not be displayed
and audible warning may not be
generated.
• You may not hear the warning sound
of Forward Collision-Avoidance
Assist if the surroundings are noisy.
• Forward Collision-Avoidance
Assist may turn off or may not
operate properly or may operate
unnecessarily depending on the road
conditions and the surroundings. WARNING
• Even if there is a problem with
Forward Collision-Avoidance
Assist, the vehicle’s basic braking
performance will operate normally.
• During emergency braking, braking
control by Forward Collision-
Avoidance Assist will automatically
cancel when the driver excessively
depresses the accelerator pedal or
sharply steers the vehicle.

Depending on the condition of the
vehicle, pedestrian and cyclist in front
and the surroundings, the speed range
to operate Forward Collision-Avoidance
Assist may reduce. Forward Collision-
Avoidance Assist may only warn the
driver, or it may not operate.
Information
• In a situation where collision is
imminent, braking may be assisted by
Forward Collision-Avoidance Assist
when braking is insufficient by the
driver.
• The images and colors in the
instrument cluster may differ
depending on the cluster type or theme
selected from the instrument cluster.
