Towing
ESSENTIAL TOWING CHECKS
Tire pressures:
Loading:
Increase rear pressures of towing vehicle by at least 3 lbf/in2 (0.2 bar) up to
maximum of 46 lbf/in2 (3.2 bar). Ensure that trailer tires are at recommended
pressures.
Keep trailer loads securely anchored, evenly distributed and as low as
possible with heavy loads over the axle. Towing vehicle maximum axle
weights and gross vehicle weight must not be exceeded.
Must be minimum of 7% of gross trailer weight up to maximum of 550 lb
Tongue weight:
Hitch height:
(250
kg) - see vehicle/trailer/tow hitch chart in ‘Technical Data’.
Must be set so that caravan/trailer is level when connected to the tow vehicle
with engine running.
Vehicle weights
Towing on severe inclines
When loading a vehicle to its maximum (GVW),
take account of the load distribution to ensure
that axle loads do not exceed the permitted
maximum values. It is your responsibility to
limit the vehicle load in such a way that neither
the maximum axle loads nor the GVW are
exceeded. The most accurate method of
determining load distribution is by using a
public weighbridge.
If a journey includes severe inclines and the
Gross Train Weight (the maximum permissible
weight of vehicle, plus trailer, see ‘TOWING
WEIGHT’, page 221) is towed, ensure that the
grille and radiator are free from obstruction and
that only high quality fuel is used. This enables
the engine and the cooling system to operate
more efficiently.
NOTE: Above 1,000 ft (300 metres) the effects
of altitude can adversely affect engine
performance and also cause overheating.
Tongue weight should be approximately 7% of
the actual trailer laden weight to maintain
optimum stability. Tongue weight can be
measured using a proprietary brand of tongue
weight indicator.
Correct gear selection will improve vehicle
performance: On vehicles with manual
transmission, select the highest practical gear
that can be maintained without causing the
engine to labour. On vehicles fitted with
automatic transmission, select ‘D’ (Drive) and,
where possible, maintain a speed that
minimises automatic gear changes.
Automatic gearbox
To avoid overheating the gearbox, it is not
advisable to tow heavy trailer loads at speeds of
less than 20 mph (32 km/h) using the main
gearbox in high range. Use the transfer gearbox
to select low range instead.
If severe inclines are encountered when towing
at high altitude and in a high ambient
temperature 86°F (30°C) or greater), the
effective Gross Train Weight will be reduced by
up to 882 lb (400 kg). Therefore, it may be
necessary to reduce the vehicle and/or trailer
weight to help counter the reduced engine
performance caused by the thinner atmosphere
experienced at high altitudes.
