that may have entered the blind spot zone.
The detection area is on both sides of your
vehicle and trailer, extending rearward
from the exterior mirrors to the end of your
trailer. When you attach a trailer and have
set up a trailer, the blind spot information
system with trailer tow becomes active
when driving forward above
6 mph
(10 km/h).
You can set up the trailer length, select a
trailer or switch blind spot information
system with trailer tow off.
Note: The system remembers the last
trailer setting when you start your vehicle.

Blind Spot Information System
Limitations
Some trailers may cause a slight change
in system performance:
•
Wide box trailers, especially those
wider than the towing vehicle, may
cause false alerts to occur when driving
next to infrastructure or near parked
cars. A false alert may also occur while
making a 90-degree turn or driving
through a roundabout.
• Wide trailers that have a total length
greater than 20 ft (6 m) may cause
delayed alerts when a vehicle is
passing at high speed. •
Box trailers that have a width greater
than
7.9 ft (2.4 m) may cause early
alerts when you pass a vehicle.
• Clam shell or V-Nose box trailers with
a width greater than 7.9 ft (2.4 m) may
cause delayed alerts when a vehicle
traveling the same speed as your
vehicle merges lanes.

Calculating the Maximum
Loaded Trailer Weight for Your
Vehicle
1. Start with the gross combined
weight rating for your vehicle
model and axle ratio. See the
previous charts.
2. Subtract all of the following
that apply to your vehicle:
• Vehicle curb weight
• Hitch hardware weight, such as
a draw bar, ball, locks or weight
distributing hardware
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage
weight
• Aftermarket equipment weight.
This equals the maximum loaded
trailer weight for this combination.
Note: The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight.
Note: Consult an authorized dealer
to determine the maximum trailer
weight allowed for your vehicle if
you are not sure. RECOMMENDED TOWING
WEIGHTS - M2 BUS
Note:
Make sure to take into
consideration trailer frontal area.
Vehicles equipped with the Trailer
Tow Package or the Heavy Duty
Payload Package should not
exceed 55 ft² (5.1 m²) trailer frontal
area.
Note: Exceeding this limitation
may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as your
vehicle's electrical system may not
include the wiring connector
needed to use electric trailer
brakes.
Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight listed for
your vehicle configuration on the
following charts.
