Trailer Recommendations
You must subtract your hitch loads from the
Cargo Weight Rating (CWR). CWR is the
maximum weight of the load your vehicle can
carry. It doesn’t include the weight of the people
inside, but you can gure about 150 lbs. (68 kg)
for each seat. The total cargo load must not
be more than your vehicles CWR.
Weigh your vehicle with your trailer attached,
so that you won’t go over the GVWR or GAWR.
If you are using a weight-distributing hitch,
weigh the vehicle without the spring bars in place.
You’ll get the best performance if you spread
out the weight of your load the right way, and if
you choose the correct hitch and trailer brakes.

Do not clean your vehicle using the following
cleaners or techniques:
Never use a knife or any other sharp object to
remove a soil from any interior surface.
Never use a stiff brush. It can cause damage
to your vehicle’s interior surfaces.
Never apply heavy pressure or rub
aggressively with a cleaning cloth. Use of
heavy pressure can damage your interior and
does not improve the effectiveness of soil
removal.
Use only mild, neutral-pH soaps. Avoid
laundry detergents or dishwashing soaps with
degreasers. Using too much soap will leave
a residue that leaves streaks and attracts dirt.
For liquid cleaners, about 20 drops per
gallon (3.78 L) of water is a good guide.
Do not heavily saturate your upholstery while
cleaning.
Damage to your vehicle’s interior may result
from the use of many organic solvents such
as naptha, alcohol, etc.
Fabric/Carpet
Use a vacuum cleaner with a soft brush
attachment frequently to remove dust and loose
dirt. A canister vacuum with a beater bar in
the nozzle may only be used on oor carpet and
carpeted oor mats. For soils, always try to remove
them rst with plain water or club soda. Before
cleaning, gently remove as much of the soil
as possible using one of the following techniques:
For liquids: gently blot the remaining soil
with a paper towel. Allow the soil to absorb into
the paper towel until no more can be
removed.
For solid dry soils: remove as much as
possible and then vacuum.
To clean, use the following instructions:
1. Saturate a lint-free, clean white cloth with
water or club soda.
2. Wring the cloth to remove excess moisture.
