WARNING (Continued)
Superlift shock absorber inflation
pressure should never operate
below t he minimum or above the
maximum values shown on the
tag attached to the infl ation valve.
Towing precautions
.
When heavily loading the vehicle
or when towing, inflate tyres to
the maximum recommended
pressure. See “Tyre placard”
under Wheels and Tyres on
page 10‑37.
.
Ensure that a load distribution
hitch is correctly distributing the
tow ball load. See “Towing and
loading equipment” earlier in this
section.
.
Ensure that superlift shock
absorbers are adjusted correctly.
See “Superlift shock absorbers”
earlier in this section.
.
Tighten the tow ball retaining nut
to 140 Y (Newton metres) and
check t he torque frequently.
.
Vehicles handle differently when
towing. Take a couple of
short-distance trips with the
trailer before taking a long trip.
.
Have the vehicle and trailer
correctly maintained and
serviced, with particular attention
given to the brakes, tyres,
suspension, wheel bearings,
towing coupling, and lighting.
.
Use an extended-arm mirror on
both sides of the vehicle if
necessary.
.
Headlights may need re-aiming
after the loaded trailer has been
hitched, particularly if a l oad
distribution hitch is not used.
.
Use a lower gear and the brakes
when descending steep hills.
.
At highway speeds it is
recommended that cruise control
is used. Cruise control prevents
thetransmissionfrom
unnecessarily changing gears,
particularly on slopes. See
Selector Lever on page 9‑ 6 for
further recommendations when
towing.
.
Do not use axle-mounted
hitches.
.
Ensure that the towbar does not
obscure the rear number plate.
Remove the towbar tongue
when not required for towing.
.
If a towbar is removed, have any
mounting holes in the underbody
sealed to prevent e ntry of
exhaust fumes, dust and water.
.
Parking Assist (PA) will require
adjustment to allow for the
installation or removal of the
towbar tongue. See “Adjustment
for a towbar” under Parking
Assist on page 9‑17.
Trailer brakes
.
Trailer brakes are mandatory on
trailers with an aggregate trailer
mass (ATM) of more than
750 kg.
