All Wheel Drive (option)
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive (option), wh\
ich means that power is distributed
automatically between the front and rear wheels. Under normal driving co\
nditions, most of the engine's power is directed
to the front wheels. However, if there is any tendency for the front whe\
els to spin, an electronically controlled coupling
distributes power to the wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size,\
construction (radial), tread pattern, load-,
speed-, traction- , temperature-, and treadwear rating. Never drive on m\
ixed tires, except for brief periods when the
temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and \
inflation pressures are shown on the tire inflation
pressure placards, located on the driver's side B-pillar (the structura\
l member at the side of the vehicle, at the rear of the
driver's door opening), or on the inside of the fuel filler door on Can\
adian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use\
only. Replace it with a full-sized tire as soon as
possible. Do not drive on the temporary spare at speeds above 50 m.p.h. \
(80km/h) or for distances greater than 50 miles
(80 km).
Never install snow chains on a temporary spare.

Towing a trailer
The maximum weights recommended by Volvo for trailers with brakes are shown in the table below.
NOTE:
l Recommended hitch tongue load: not more than 10% of the trailer's weight\
. The trailer load should be positioned
so that it does not shift and the tongue load should be 10% of the trail\
er's weight. However, the tongue load should not
exceed the maximum permissible weights indicated in the table above.
l When towing trailers without brakes, the maximum permissible trailer weight is 1,700 lbs (750 kg).\
l If necessary, redistribute the weight of any cargo in the trailer to avo\
id excessive weight on the trailer hitch.
l The maximum trailer weight listed in the table for All Wheel Drive model\
s, 5,000 lbs (2250 kg) is only applicable when
there are not more than two occupants in the vehicle, in the front seats\
, with a combined weight of 300 lbs (135 kg), with
no other cargo in the vehicle.
l The maximum weight listed for Front Wheel Drive models, 4,000 lbs (1800\
kg) is only applicable when there are not
more than four occupants in the vehicle, in the front seats and second r\
ow of seats, with a combined weight of 600 lbs (270
kg), with no other cargo in the vehicle.
pg. 138 Starting and driving
Towing a trailer
l Please be aware that the load on the trailer hitch is part of the vehicl\
e's total load carrying capacity. The amount of cargo
in the vehicle and the trailer must be limited so that the gross vehicle\
weight and maximum permissible rear axle weight
(see
page 209) are not exceeded.
l Vehicles used for towing a trailer on a regular basis, or for long-dista\
nce highway towing should be equipped with an
automatic transmission oil cooler and Volvo's automatic self-leveling sy\
stem for the rear suspension. Consult your Volvo
retailer.
l Volvo recommends the use of Volvo trailer hitches that are specially des\
igned for the vehicle.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch installation should not
interfere with the proper operation of this bumper system.
l Increase tire pressure to recommended full inflation pressure. See chapt\
er "Wheels and tires."
l When your vehicle is new, avoid towing heavy trailers during the first 6\
20 miles (1,000 km).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should be closely

watched when driving in hot climates or hilly terrain. Use a lower gear \
and turn off the air conditioner if the temperature
gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check and observe state/
local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in mountainous areas.
NOTE:
l When parking the vehicle with a trailer on a hill, apply the parking bra\
ke before putting the gear selector in (P)ark.
When starting on a hill, put the gear selector in (D)rive before relea\
sing the parking brake. Always follow the trailer
manufacturer's recommendations for wheel chocking.
l If you use the manual (Geartronic) shift positions while towing a trai\
ler, make sure the gear you select does not put too
much strain on the engine (using too high a gear).
WARNING!
l Bumper-attached trailer hitches must not be used on Volvos, nor should s\
afety chains be attached to the bumper.
l Trailer hitches attaching to the vehicle rear axle must not be used.
l Never connect a trailer's hydraulic brake system directly to the vehicle\
brake system, nor a trailer's lighting system
directly to the vehicle lighting system. Consult your nearest authorized\
Volvo retailer for correct installation.
l When towing a trailer, the trailer's safety wire must be correctly faste\
ned to the hole or hook provided in the trailer
hitch on the vehicle. The safety wire should never be fastened to or wou\
nd around the drawbar ball.

Smoother starts with a trailer
Models equipped with the V8-engine and the 6-speed automatic transmissio\
n have a built-in function that reduces
acceleration slightly in first gear when the vehicle is towing a trailer\
. This is done to help avoid wheel spin and to make
starting off smoother.
l This function is activated when the trailer's electrical connector is pl\
ugged into the electrical socket mounted near the
trailer hitch.
l The function is automatically deactivated when the trailer's wiring is d\
isconnected from the socket. The vehicle will
then accelerate normally.
NOTE: Since this function is activated when a connector is plugged into the e\
lectrical socket near the trailer hitch, it will
be activated by any electrical equipment (e.g. bicycle racks with light\
ing, etc) that is plugged in, and will remain active
until the equipment is unplugged from the socket.
Leveling
If your vehicle is equipped with automatic leveling, the rear suspension\
always retains the correct ride height regardless of
the load.
l The system adjusts the rear suspension to the correct level after the ve\
hicle has been driven a short distance.
