The vehicle must be moving above 6 mph (10 km/h) to
activate the feature. Once the trailer has been detected, the
system will default to the maximum blind spot zone until
the length has been verified. You will see “Auto” in the
instrument panel cluster .
• Max Mode — When “Max Mode” is selected, the system
will default to the maximum blind spot zone regardless of
what size trailer is attached
NOTE:
Selected setting is stored when the ignition is cycled OFF. To
change this setting, it must be selected through the Uconnect
Settings. Refer to “Uconnect Settings” in “Multimedia” for
further information.
Trailer Length Detection
Once the trailer presence has been established. The trailer
length will be established (by making a 90 degree turn) and
then the trailer length category (example 10-20 ft (3 m to
6 m)) will be displayed. This can take up to 30 seconds after
completing the turn. NOTE:
During the same ignition cycle, if the vehicle is at a standstill
for a minimum of 90 seconds, a new “trailer detection
request” is enabled by the system once the vehicle resumes
motion.
Maximum length supported by the Trailer Merge Assist
feature is 39.5 ft (12 m). Trailer length is considered the
forward most portion of the trailer hitch to the rearward
most portion of the body, bumper, or ramp of the trailer.
Maximum width supported by the Trailer Merge Assist
feature is 8.5 ft (2.59 m). Trailer width is measured at the
widest portion of the trailer and may include wheels, tires,

• The TPMS is not a substitute for proper tire maintenance,and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
Tire Pressure Monitor Display The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure readings to
the receiver module.
NOTE:
It is particularly important for you to check the tire pressure
in all of the tires on your vehicle monthly and to maintain the
proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light

you visit an authorized dealer at your earliest possible
convenience. An authorized dealer has diagnostic equip-
ment to assess the condition of your transmission.
If the transmission cannot be reset, an authorized dealer
service is required.
Electronic Range Select (ERS) Operation — Eight-Speed
Transmission
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the transmis -
sion is in DRIVE. For example, if you set the transmission
gear limit to 4 (fourth gear), the transmission will not shift
above fourth gear (except to prevent engine overspeed), but
will shift through the lower gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the transmission gear selector is in
DRIVE, the transmission will operate automatically, shifting
between all available gears. Tapping the GEAR- switch (on
the steering wheel) will activate ERS mode, display the
current gear in the instrument cluster, and set that gear as the
top available gear. Once in ERS mode, tapping the GEAR- or
GEAR+ switch will change the top available gear. Electronic Range Select (ERS)
To exit ERS mode, simply push and hold the GEAR+ switch
until the gear limit display disappears from the instrument
cluster.
