ECC functions
1. Auto - On/Off
The AUTO function automatically regulates climate control to maintain the desired temperature. The automatic
function controls heating, air conditioning, blower speed, recirculation, and air distribution.
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. AUTO CLIMATE is shown in the display.
2. Blower speed
The blower speed can be increased or decreased by turning the knob. The blower speed is regulated
93 03 Climate

automatically if AUTO is selected. The previously set blower speed is disconnected.
NOTE
If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air
conditioning are switched off. The display shows the blower symbol and OFF.
3. Recirculation
This function can be used to shut out exhaust fumes, smoke, etc from the passenger 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.
Timer
The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected. See page 77
for information on setting 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 windshield and side windows and increases blower speed. When the defroster is activated:
Air flows to the windows at high blower speed.
The LED in the defroster button lights up when this function is activated. The air conditioning system is controlled
to provide maximum air dehumidification.
The air conditioning is automatically switched on (can be switched off by pressing 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
climate control panel and a lit LED in the selected button indicate that the manual function has been selected. With
manually selected airflow both warm and cool air can be selected. See also the table on page 95
.
6. Air conditioning On/Off
ON: The air conditioning system is engaged when the ON light is lit and is controlled automatically by the system to
maintain the selected temperature.
OFF: The system is disengaged when the OFF lights up.
When OFF is selected and the OFF LED is lit, the air conditioning system is deactivated. Other functions are still
controlled automatically.
When Defroster (4) is selected, the air conditioning system is activated for maximum dehumidifying.

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 window and door mirrors.
The rear window and door mirrors are defrosted simultaneously if the switch is pressed once. The defrost function is
active if the LED in the switch is illuminated.
The function can be switched off manually by pressing the button.

Do not connect the jumper cable to any part of the fuel system or to any moving parts. Avoid touching hot
manifolds.
Batteries generate hydrogen gas, which is flammable and explosive.
Battery fluid contains sulfuric acid. Do not allow battery fluid to contact eyes, skin, fabrics or painted surfaces. If
contact occurs, flush the affected area immediately with water. Obtain medical help immediately if eyes are affected.
Never expose the battery to open flame or electric spark.
Do not smoke near the battery.
Failure to follow the instructions for jump starting can lead to personal injury.
Do not touch the jumper cables during the attempt to start the vehicle. This could cause sparks.
154 06 Starting and driving
Towing a trailer
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 249
for the location of the VIN plate), may not be used to tow trailers 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 bumpers. 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 consideration:
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 m.p.h. (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 conditioner 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 operation.
Hauling a trailer affects handling, durability, 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
Exceeding the permissible axle weight, gross vehicle weight, or any other weight rating limits can cause tire
overheating resulting in permanent deformation or catastrophic failure.
Do not use replacement tires with lower load carrying capacities than the tires that were original equipment on the
vehicle because this will lower the vehicle's GVW rating. Replacement tires with a higher limit than the originals do
not increase the vehicle's GVW rating limitations.

Uniform tire quality gradings
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 applicable, on the tire sidewall between the tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 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 significantly from the norm due to variation in driving habits,
maintenance practices and differences in road characteristics and climate.
TRACTION
The traction grades, from highest to lowest, are AA, A, B, and C, as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The traction
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.
TEMPERATURE
The temperature grades are AA (the highest), A, 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
