Towing a Trailer
To achieve a proper tongue load,
start by loading 60 percent of the
load toward the front of the trailer
and 40 percent toward the rear, then
re-adjust the load as needed.
Gross Vehicle Weight Rating

The maximum allowable weight of
the vehicle, all occupants, all cargo,
and the tongue is:
(DX, LX, Canadian DX-G)
3,671 lbs (1,665 kg)
(EX)

Gross Axle Weight Rating
(GAWR):
The maximum allowable weight of
the vehicle axles is:
(DX, LX, Canadian DX-G)
1,940 lbs (880 kg)
on the front axle
1,731 lbs (785 kg)
on the rear axle
(EX)
1,973 lbs (895 kg)
on the front axle
1,764 lbs (800 kg)

Checking Loads
The best way to confirm that vehicle
and trailer weights are within limits
is to have them checked at a public
scale.
Using a suitable scale or a special
tongue load gauge, check the tongue
load the first time you set up a
towing combination (a fully-loaded
vehicle and trailer), then recheck the
tongue load whenever the conditions
change.
