WARNING!
Failure to load trailers heavier in front
is the cause of many trailer accidents.
Never exceed the maximum tongue
weight stamped on your trailer hitch.
Tire Pressure Adjustment
Proper tire inflation pressures of your
vehicle and trailer are essential to the
safe and satisfactory operation of your
vehicle while driving and in manoeuvres.
Check for signs of tire wear or visible
tire damage on trailer and vehicle before
towing a trailer.
For more information on vehicle tires,
: chapter "Tires Information" in
section "Safety".
When a trailer must be towed, inflate
vehicle tires to full load recommended
pressure (FLC), : chapter "Tire
Inflation Pressure" in section "Technical
Specifications".
For pressure of trailer tires, follow
the instructions given by the trailer
manufacturer.
After adjusting vehicle tire pressure and
connecting and disconnecting the trailer,
initialise the Tire Pressure Monitoring
System (TPMS), : chapter "Tire
Pressure Monitoring System (TPMS)" in
section "Safety".
Field of Vision of External Rear
View Mirrors
Law provisions require the field of vision
of external rear-view mirrors to include
the rear trailer corners.
If vehicle external rear-view mirrors
cannot cover the required field of
vision, it is possible to install additional
rear-view mirrors sticking further out at
the sides.
The Service Network can provide you
with information about towing a trailer
and about the approved components
available in the "Genuine Accessories"
range.
