The BSI alert indicator starts to blink
as a reminder if you move the turn
signal lever in the direction of the
detected vehicle.
Radar sensors, located underneath
each corner of the rear bumper,
detect objects. Do not cover this area
with labels or stickers of any kind.
Always keep this area is free of any
kind of dirt every time you get in the
vehicle.
Impacts to the radar sensors or the
area around them can affect system
performance. If an impact occurs,
have the system checked by your
dealer.

Important Precautions
Like all assistance systems, BSI has
limitations. Over-reliance on BSI may
result in a collision. Always look in
your mirrors, to either side of your
vehicle, and behind you for other
vehicles before changing lanes.The system should be turned off
when towing a trailer. Due to the
added mass and resulting changes in
radar coverage, the system cannot
operate as intended, and detection of
the trailer itself by the radar sensors
may cause the BSI alert indicators to
illuminate.Limitations
The BSI alert indicators may not
illuminate under the following
circumstances:
●
The speed difference between
your vehicle and a vehicle
approaching from behind is
greater than 31 mph (50 km/h).
●
A vehicle is parked in a side lane.
●
The speed difference between
your vehicle and the vehicle you
are passing is greater than 6 mph
(10 km/h).
●
An object not detected by the
radar sensors approaches or
passes your vehicle.

BSI may be adversely affected under
the following circumstances:●
When objects such as guard rails,
poles, trees, etc., are detected.
●
When an object that doesn't reflect
radio waves well, such as a
motorcycle, is in the alert zone.
●
A vehicle is behind or approaching
your vehicle while on a curved
road.
●
When towing a trailer.
●
A vehicle is moving from a far lane
to the adjacent lane.
●
The system picks up external
electrical interference.
●
The rear bumper has been
deformed, or improperly repaired.
●
The orientation of the sensors has
been changed.
●
Bad weather conditions, such as
heavy rain, snow and fog.The system is for your convenience.
Even if an object is within the alert
zone, the system may not detect it,
depending on its shape.
Always look in your mirrors, to either
side of your vehicle, and behind you
for other vehicles before changing
lanes.EXAMPLES

Active Damper SystemIf equippedThe active damper system is always
on, constantly adjusting your
vehicle's dampers to the best settings
for current road conditions along
with vehicle speed and handling
inputs. The system uses electrically
controlled dampers to enhance
handling precision, vehicle
composure, tire to road adhesion and
rough road ride comfort isolation.
The system reacts to inputs from
various electronic sensors to give
exactly the right amount of
suspension damping to provide
optimal ride comfort and handling.

Your vehicle has been designed
primarily to carry passengers and
their cargo. You can also use it to tow
a trailer if you carefully observe the
load limits, use the proper
equipment, and follow the guidelines
in this section.
If your vehicle is equipped with the
blind spot information system (BSI),
do not use it when towing a trailer.
For more information see page 476.Break-In PeriodAvoid towing a trailer during your
vehicle's first 600 miles (1,000 km)
(see page 418).
Be sure to read theOff-Highway
Driving Guidelines section on page
494 if you plan to tow off paved
surfaces. Your vehicle is equipped with a
trailer stability assist to help stabilize
the vehicle/trailer combination by
reducing the vehicle speed. For more
information, see page 492.
Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
before starting to drive.
Load Limit
Total Trailer WeightThe maximum allowable weight of
the trailer and everything in or on it
depends on the number of occupants
in your vehicle and the type of trailer
being towed (see page 484).
Towing a trailer that is too heavy can
seriously affect your vehicle's
handling and performance. It can
also damage the engine and
drivetrain.

Use this illustration to identify each
terminal in the trailer brake
controller connector.
Safety ChainsAlways use safety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and can catch the trailer if it becomes
unhitched. Leave enough slack to
allow the trailer to turn corners
easily, but do not let the chains drag
on the ground.Sway ControlThis device is recommended if your
trailer tends to sway. Your trailer
maker can tell you what kind of sway
control you need and how to install it.Trailer MirrorsMany states and provinces require
special exterior mirrors when towing
a trailer. Even if they don't, you
should install special mirrors if you
cannot clearly see behind you, or if
the trailer creates a blind spot.
Spare TiresWhen towing a trailer, we
recommend that you carry a full-size
spare wheel and tire for your vehicle
and trailer. See page 539 for proper
tire size, page 545 for how to store a
full size wheel and tire, and page 545
for information on changing a flat
tire.
Remember to unhitch the trailer
before changing a flat. Ask your
trailer sales or rental agency where
and how to store the trailer's spare
tire.
