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
trailer'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 wei\
ght 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 vehicl\
e, in the front seats, with a
combined weight of 300 lbs (135 kg), with no other cargo in the vehicl\
e.
pg. 105 Starting and driving
Towing a trailer (contd)
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 row of seats,
with a combined weight of 600 lbs (270 kg), with no other cargo in the\
vehicle.
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 th\
at the gross vehicle weight and
maximum permissible rear axle weight
(see page 173) 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 system 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 bump\
er 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).

Owner maintenance
Periodic maintenance requirements and intervals are described in your ve\
hicle's Warranty and Service
Records Information booklet.
The following points can be carried out between the normally scheduled m\
aintenance services.
Each time the car is refueled:
l Check the engine oil level
l Clean the windshield, windshield wipers, headlights, and tail lights
Monthly:
l Check cold tire pressure in all tires. Inspect the tires for wear.
l Check that engine coolant and other fluid levels are between the indicat\
ed "min" and "max" markings.
l Clean interior glass surfaces with a glass cleaner and soft paper towels\
.
l Wipe driver information displays with a soft cloth.
l Visually inspect battery terminals for corrosion. Corrosion may indicate\
a loose terminal connector, or
a battery near the end of its useful service life. Consult your Volvo re\
tailer for additional information.
As needed:
l Wash the car, including the undercarriage, to reduce wear that can be ca\
used by a buildup of dirt, and
corrosion that can be caused by salt residues.
l Clean leaves and twigs from air intake vents at the base of the windshie\
ld, and from other places
where they may collect.

Emission inspection readiness
What is an Onboard Diagnostic System (OBD II)?
OBD II is part of your vehicle's computerized engine management system. \
It stores diagnostic
information about your vehicle's emission controls. It can light the Che\
ck Engine light (MIL) if it detects
an emission control "fault." A "fault" is a component or system that is \
not performing within an expected
range. A fault may be permanent or temporary. OBD II will store a messag\
e about any fault.
How do states use OBD II for emission inspections?

WARNING!
The engine must not be running when this check is
performed.
Check coolant level
The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level regularly. The level should be between the "MAX" and "\
MIN" marks on the expansion
tank. The check should be made with particular thoroughness when the eng\
ine is new or when the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\
r and antifreeze). CAUTION
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/
coolant may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the v\
ehicle
cools.

Washer fluid reservoir
Washer fluid reservoir
The washer fluid reservoir is located in the engine compartment and hold\
s approx. 6.8 US qt (6.5 liters).
When there is less than approximately 1 US qt (1 liter) remaining in t\
he reservoir, the washer fluid spray
will be directed to the windshield only.
During cold weather, the reservoir should be filled with windshield wash\
er solvent containing antifreeze.

Coolant reservoir
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only (a 50/50 mix of wate\

Check coolant regularly!
WARNING!
- Never remove the radiator cap while the engine is warm. Wait until the\
vehicle cools.
- If it is necessary to top up the coolant when the engine is warm, unsc\
rew the expansion tank cap
slowly so that the overpressure dissipates.

Oil and fluids (contd)
Brake fluid reservoir
The brake fluid should always be above the MIN mark on the side of the r\
eservoir. Check, without
removing the cap, that there is sufficient fluid in the reservoir.
Fluid type : DOT 4+ boiling point >536°F (280°C), P/N 9437433
Replace : Every second year or 30,000 miles (48,000 km). The fluid should be rep\
laced once a year or
every 15,000 miles (24,000 km) when driving under extremely hard condi\
tions (mountain driving, etc.)
