NOTE
•When parking the vehicle with a trailer
on a hill, apply the parking brake before
putting the gear selector in P. Always
follow the trailer manufacturer's recom-
mendations for wheel chocking.
•When starting on a hill, put the gear
selector in D before releasing the park-
ing brake. See also page 119 for more
detailed information about starting off
on a hill while towing a trailer.
•If you use the manual (Geartronic) shift
positions while towing a trailer, make
sure the gear you select does not put
too much strain on the engine (using too
high a gear).
•The drawbar assembly/trailer hitch may
be rated for trailers heavier than the
vehicle is designed to tow. Please
adhere to Volvo's recommended trailer
weights.
•Avoid driving with a trailer on inclines of
more than 15 %.
Trailer cableAn adapter is required if the vehicle's trailer
hitch has a 13-pin connector and the trailer has
7 pins. Use an adapter cable approved by
Volvo. Make sure the cable does not drag on
the ground.

Installing the ball holder1. If necessary, remove the cotter pin from
the locking bolt and slide the locking bolt
out of the hitch assembly.
2. Slide the ball holder into the hitch assem-
bly.
3. Align the hole in the ball holder with the one
in the hitch assembly.4. Slide the locking bolt through the hitch
assembly/ball holder.
5. Insert the cotter pin in the hole at the end
of the locking bolt.
Removing the ball holder1. Remove the cotter pin from the locking bolt
and slide the locking bolt out of the ball
holder/hitch assembly.
2. Pull the ball holder out of the hitch assem-
bly.
NOTE
A cover for the hitch assembly is also
included in the kit.
Trailer Stability Assist (TSA)
Trailer Stability Assist is a system designed to
help stabilize a vehicle that is towing a trailer
when the vehicle and trailer have begun to
sway and is part of the Dynamic Stability and
Traction Control system (DSTC). See page
144 for information on DSTC.
FunctionA vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at
high speeds but, for example, if the trailer is
overloaded or if the load is unevenly distributed
in the trailer, there is risk of swaying at speeds

Uniform Tire Quality Grading

Quality grading information
ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked Cmay have poor traction performance. The trac-
tion grade assigned to this tire is based on
braking (straight-ahead) traction tests and is
not a measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.
TEMPERATUREThe temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a minimum level of performance that all pas-
senger vehicle tires must meet under the Fed-
eral Motor Safety Standard No. 109. Grades B
and A represent higher levels of performance
on the laboratory test wheel than the minimum
required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
