ECC functions1. Auto – On/Off
TheAUTO function automat-
ically regulates climate con-
trol to maintain the desired
temperature. The automatic
function controls heating, air
conditioning, blower speed,
recirculation, and air distribu-
tion.
If you select one or more manual functions, the
remaining functions continue to be controlled
automatically. All manual settings are switched
off when AUTO is switched on.

3. Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e. no air
from outside the car is taken
into the car when this function is activated.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.TimerThe timer function minimizes the risk of fogging
or stale air when the recirculation function is
selected, see page 83 for information on set-
ting the recirculation timer.
NOTE
Recirculation is always disengaged if the
defroster button is engaged to clear ice or
condensation from the side windows.
4. Defroster
Directs airflow to the wind-
shield and side windows and
increases blower speed.
When the defroster is acti-
vated:
•
Air flows to the windows at high blower
speed.
•
The LED in the defroster button lights up
when this function is activated. The air con-
ditioning system is controlled to provide
maximum air dehumidification.
•
The air conditioning is automatically
switched on (can be switched off by press-
ing button 6).
The air is not recirculated.
5. Airflow controls
Press one of the three buttons
in the illustration to activate
the selected airflow. A symbol
in the display above the cli-
mate control panel and a lit
LED in the selected button
indicate that the manual func-
tion has been selected. With manually selected
airflow both warm and cool air can be selected.
See also the table on page 99.
6. Air conditioning On/Off
ON: The air conditioning sys-
tem is engaged when the ON
light is lit and is controlled
automatically by the system
to maintain the selected tem-
perature.
OFF: The system is disengaged when the
OFF lights up
WhenOFF is selected and the OFF LED is lit,
the air conditioning system is deactivated.
Other functions are still controlled automati-
cally.
When Defroster (4) is selected, the air condi-
tioning system is activated for maximum dehu-
midifying.7 and 8. Heated front seats (option)
Maximum heating: Press the
button once – both LEDs light
up.
Reduced heating: Press the
button a second time – one
LED lights up.
Seat heating off: Press the button a third time
– no LEDs are lit.

9. Rear window and door mirror
defrosters
Press to defrost the rear win-
dow and door mirrors.
The rear window and door
mirrors are defrosted simulta-
neously if the switch is
pressed once. The defrost
function is active if the LED in the switch is illu-
minated.
•
The function can be switched off manually
by pressing the button.
•
The defrost function switches off automat-
ically after 12–20 minutes, depending on
the outside temperature.NOTE
•
On certain markets, the defrost function
may remain on longer than 20 minutes
in cold weather to help keep the rear
window free from ice or condensation.
10. Temperature selector
The temperatures on the driv-
er's and passenger's sides
can be set separately using
the knob (with the thermome-
ter in it). The temperature can
be set for both sides of the car
when the ignition is switched
on (both LEDs will be on), which means that a
temperature setting will apply to both sides of
the car.
To set the temperature on one side of the car:
1. Press the knob once. The LED for one side
of the car will light up. Turn the knob to
adjust the temperature.
2. Press the knob a second time to set the
temperature on the opposite side of the
car.
3. Press the knob a third time to set the tem-
perature on both sides of the car at the
same time.
NOTE
Selecting a temperature that is higher or
lower than necessary will not heat or cool
the passenger compartment faster.

06 Starting and drivingTowing a trailer
06160
General information•
Volvo recommends the use of Volvo trailer
hitches that are specially designed for the
vehicle.CAUTION
Models equipped with the B5244S7 engine
(engine code 39 , which is the 6th and
7th digits from the left in your vehicle's VIN
number, see page 262 for the location of
the VIN plate), may not be used to tow trail-
ers or vehicles of any kind. This could cause
damage to the vehicle's emission control
systems.Maximum trailer weights recommended by
Volvo are:•
Trailers without brakes: 1,540 lbs
(700 kg).
•
Trailers with brakes: 2,000 lbs (900 kg)
Observe the legal requirements of the
state/province in which the vehicles are
registered.
•
The maximum recommended hitch
tongue load is 165 lbs (75 kg).
•
All Volvo models are equipped with
energy-absorbing shock-mounted bump-
ers. Trailer hitch installation should not
interfere with the proper operation of this
bumper system.Trailer towing does not normally present any
particular problems, but take into considera-
tion:
•
Increase tire pressure to recommended
full. See the chapter "Wheels and tires."
•
When your vehicle is new, avoid towing
heavy trailers during the first 620 miles
(1,000 km).
•
Maximum speed when towing a trailer:
50 mph (80 km/h).
•
Engine and transmission are subject to
increased loads. Therefore, engine coolant
temperature should be closely watched
when driving in hot climates or hilly terrain.
Use a lower gear and turn off the air con-
ditioner if the temperature gauge needle
enters the red range.
•
If the automatic transmission begins to
overheat, a message will be displayed in
the information display.
•
Avoid overload and other abusive opera-
tion.
•
Hauling a trailer affects handling, durabil-
ity, and economy.
•
It is necessary to balance trailer brakes
with the towing vehicle brakes to provide a
safe stop (check and observe state/local
regulations).
•
Do not connect the trailer's brake system
directly to the vehicle's brake system.
•
More frequent vehicle maintenance is
required.
•
Remove the ball and drawbar assembly
when the hitch is not being used.
•
Volvo recommends the use of synthetic
engine oil when towing a trailer over long
distances or in mountainous areas.WARNING
•
Bumper-attached trailer hitches must
not be used on Volvos, nor should
safety chains be attached to the
bumper.
•
Trailer hitches attaching to the vehicle's
rear axle must not be used.
•
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 trained
and qualified Volvo service technician
for correct installation.
•
When towing a trailer, the trailer's safety
wire must be correctly fastened to the
hole or hook provided in the trailer hitch
on the vehicle. The safety wire should
never be fastened to or wound around
the drawbar ball.

07 Wheels and tiresUniform tire quality gradings

185 Uniform tire quality gradings
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 ATREADWEARThe 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 C
may 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 AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions 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 corre-
sponds to a minimum level of performance that
all passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance 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.
