or electrical system damage may
occur.

Tyres
WARNING
When towing a trailer, it is very
important for your vehicle and trailer
to have properly inflated tyres. Your
vehicle's tyres should be inflated to
the pressures listed on your vehicle's
tyre information label. If laden pres-
sures are listed on the label, the tyres
should be inflated to the laden pres-
sures. Inflate trailer tyres according
to the specifications provided by the
trailer manufacturer.
Mirrors
Check if your vehicle's mirrors meet local
requirements for mirrors used on towing
vehicles. If they do not, you must install the
required mirrors before you tow.
Vehicle/trailer loading
To load your vehicle and trailer properly,
you must know how to measure gross
trailer weight and trailer nose weight.
Gross trailer weight is the weight of the
trailer plus all the cargo in it. You can mea-
sure gross trailer weight by putting the fully
loaded trailer on a vehicle scale.
Nose weight is the downward force
exerted on the tow bar by the trailer cou-
pler, with the trailer fully loaded and the
coupler at its normal towing height. This
weight can be measured using a bathroom
scale.
The weight of your loaded trailer (gross
trailer weight) should never exceed towing
capacity.
Distribute cargo in your trailer so that nose
weight is about 10% of gross trailer weight,
but does not exceed "Maximum vertical
load" of 60 kg (132 lbs), and does not fall
below 25 kg (55 lbs) or 4%, whichever is
heavier, on trailer hitch point. You should
measure gross trailer weight and nose
weight before towing to check that your
load is properly distributed.
WARNING
Improper weight distribution of your
trailer may result in poor vehicle han-
dling and swaying of the trailer.
Always check that trailer nose weight
is about 10% of gross trailer weight,
but does not exceed "Maximum verti-
cal load" of 60 kg (132 lbs), and does
not fall below 25 kg (55 lbs) or 4%,
whichever is heavier, on trailer hitch
point. Also check that the cargo is
properly secured. Failure to observe
this requirement may result in an
accident.
