Driving
the driver to control. You could lose
control of your vehicle and have a
collision.
• When hauling cargo or towing a
trailer, do not overload your vehicle
or trailer. Overloading can cause a
loss of control, damage to brakes,
driveline, steering, suspension or
tires.
• Safety metal wire must always be
used between your vehicle and
trailer. Always connect the wire to
the hook retainers of the trailer and
vehicle hitch. Cross the wire under
the trailer tongue and allow enough
slack for turning corners.

• Comply with local applicable speed
limits.
• Towing any trailer will increase your
stopping distance. When towing, you
should allow for additional space
between your vehicle and the vehicle
in front of you. Failure to do so could
result in an accident.
• For towing use ride height "Normal".
• Adjust speed when towing a trailer.
Depending on towed load and
weather conditions, trailer might
sway at a speed above 80 km/h (50
mph).
• If trailer sways, driver can
restore vehicle-trailer stability by
346
immediately braking in a firm
manner.
• When towing a trailer, never exceed
100 km/h (62 mph). The high
axial load developed under these
conditions might damage tires.
• Do not exceed maximum specified
pressure for vehicle and trailer tires.
• Considering the large dimensions
of the vehicle-trailer assembly, any
indispensable correction of trajectory
must be performed with great care
to avoid any damage to other road
users.
• To ensure other vehicles' safety and
avoid hindering smooth traffic flow,
towing a trailer is allowed on roads
with a maximum grade of 12%.
• In case of hill start, the Hill Start
Assist system (HSA, see "Brake and
Stability Control Systems" in this
section) can manage brake system
intervention at best.
• Vehicles with trailers should
not be parked on a steep grade.
When parking, put the tow vehicle
transmission in P (Park) and apply the
parking brake on the tow vehicle.
Always, block or "chock" the trailer
wheels.
• On steep downhill roads, the vehicle-
trailer assembly will tend to sway
more easily. Before driving downhill,
manually engage lower gear and
drive slowly.
• Do not use electronic Cruise Control
(CC and/or ACC) when driving on
slopes or when carrying heavy loads.
• The D (Drive) gear must be selected
when towing. The transmission
controls include a drive strategy to
avoid frequent shifting when towing.
However, if frequent shifting does
occur while in D (Drive), if foreseen,
you can use the paddle shift switches
to manually select a lower gear.
• Using a lower gear while operating
the vehicle under heavy loading
conditions, will improve performance
and extend transmission life by
reducing excessive shifting and heat
buildup. This action will also provide
better engine braking.
Trailer Tongue Maintenance
To ensure correct operation of the
system, periodically remove all
deposits of dirt which may have
accumulated on the ball head bar and
from the mounting pipe.
The possible key locking must only be
treated with graphite.
Periodically lubricate the joints, the
sliding surfaces and the ball with
grease without resin or oil. Lubrication
is also a further corrosion protection.
