Front/rear park assist (accessory/option)
Front/rear park assist
The park assist system(s) are designed to assist you when driving into\
parking spaces, garages, etc. They utilize ultrasound
sensors located in the bumpers to measure the distance to a vehicle or o\
ther object, or a person who may be close to the
front or rear of the vehicle.
When is park assist active
Front: the system is active from the time the engine is started until the vehi\
cle exceeds a speed of approximately 10 mph
(15 km/h). It is also active when the vehicle is backing up. Front par\
k assist reactivates automatically when the vehicle's
speed goes under 10 mph (15 km/h).
Rear: the system is active when the engine is running and reverse gear is sel\
ected.
NOTE:
l If the vehicle is equipped with front and rear park assist, both systems\
will either be activated or deactivated together.
They cannot be used separately.
l The indicator light in the button (see the illustration on page 52) will light up to indicate that park assist system(s) are
activated.
When park assist is actively working:
l The audio system's volume will be reduced.
l An intermittent signal will be audible from the speakers to indicate tha\
t you are approaching a person, object, parked
vehicle, etc. The signals begin when the distance between the bumper and\
the object is:
Rear: approximately 5 feet (1.5 meters)
Front: approximately 2.5 ft (0.8 meters)

l At a distance of approximately 1 foot (30 cm), the signal will become \
constant. If objects are close to both the front and
rear bumpers, the signal will alternate between the front and rear speak\
ers.
Deactivating the system(s)
- Press the Park assist button on the center console (see
page 52) to temporarily deactivate the system(s).
- The indicator light in the button will go out when the system(s) hav\
e been deactivated.
- If the vehicle is equipped with front and rear park assist, both syste\
ms will be deactivated by pressing the button.
Park assist will be automatically reactivated the next time the engine i\
s started.
NOTE: It may be necessary to deactivate one or both of the park assist system\
s in certain cases.
l Rear park assist: towing a trailer, carrying bicycles in a rear-mounted carrier, etc, co\
uld trigger the rear park assist
system's sensors.
l Front park assist: it may not be possible to combine auxiliary headlights and front park \
assist since these lights could
trigger the system's sensors.

Faults in the system
If the yellow warning symbol illuminates and a message is shown in the i\
nformation display, the system is not
functioning properly. Consult a Volvo retailer or authorized service tec\
hnician.
Cleaning the sensors
For the system to function properly, the sensors in the front and/or rea\
r bumpers should be kept clean. They can be cleaned
with car washing detergent and a sponge.
WARNING!
These systems are designed to be a supplementary aid when parking the ve\
hicle. They are not, however, intended to
replace the driver's attention and judgement.
CAUTION!
In certain circumstances, the park assist system may give unexpected war\
ning signals that can be caused by external
sound sources that use the same ultrasound frequencies as the system. Th\
is may include such things as the horns of
other vehicles, wet tires on asphalt, pneumatic brakes, motorcycle exhau\
st pipes, etc. This does not indicate a fault in
the system.

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.

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.

Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze protection. This
gives protection against freezing down to -31°F (-35°C). See sec\
tion "Coolant". The use of "recycled" antifreeze is not
approved by Volvo. Different types of antifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer stocks plenty of
Volvo engine coolant to protect your vehicle during cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In addition, in extremely
cold weather conditions it is worthwhile to add fuel line de-icer before\
refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weat\
her starting as well
as decreasing fuel consumption while the engine is warming up. For winte\
r use, 5W-30 oil, particularly the synthetic type
1,
is recommended. Be sure to use good quality oil but do not use cold-weat\
her oil for hard driving or in warm weather. See
section "Engine oil" for more information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
. are used more
often. Moreover, the capacity of the battery decreases as the temperatur\
e drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check th\
e state of charge more frequently and spray an
antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter driving - see section "Wheels and tires."\

l To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 188 for the
location of the washer fluid reservoir). This is important since dirt i\
s often splashed on the windshield during winter
driving, requiring the frequent use of the washers and wipers. Volvo Was\
her Solvent should be diluted as follows:
- Down to 14° F (-10° C): 1 part washer solvent and 4 parts water
- Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
- Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
- Down to -18° F (-28° C): 1 part washer solvent and 1 part water
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
