Air conditioning - A/C
Your car is equipped with a climate control system that includes either manually adjustable air conditioning or optional
Electronic Climate Control (ECC).
The air conditioning system can be switched off, but for optimal air quality in the passenger compartment and to
prevent the windows from fogging, the air conditioning should be left on - even in cool weather.
NOTE: In warm weather, a small amount of water may accumulate under the car when it has been parked. This water
is condensation from the A/C system and is normal.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate control maintenance
Your Volvo retailer has the tools and equipment required to maintain and carry out any necessary repairs on the
climate system. Work of this type should only be done by an authorized Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance will not deplete the ozone layer. The system contains 1.2 lbs (530 g) R134a (HFC 134a), and uses PAG
oil.
Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult your Volvo retailer for these intervals. The filter should be replaced more
often when driving under dirty and dusty conditions. The filter cannot be cleaned and therefore should always be
replaced with a new one.
NOTE: There are different types of cabin air filters. Ensure that the correct type is installed.
Display

Drive carefully and avoid rapid acceleration and hard braking.
Use the transmission's (D)rive position as often as possible and avoid using kickdown.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the vehicle.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc, increase air resistance and also fuel consumption.
At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
WARNING!
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
pg. 99 General information
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to -31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze
is not approved by Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator. Your Volvo retailer stocks plenty
of Volvo engine coolant to help protect your vehicle during cold weather.

WARNING!
The cooling fan may start or continue to operate (for up to 6 minutes) after the engine has been switched off.

Changing engine oil and oil filter
Refer to the Warranty and Service Records Information booklet for information on the oil change intervals. See page
187 for oil specifications.
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to
the first scheduled maintenance service.
CAUTION!
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Always add oil of the same type and viscosity as already used.
The car should be parked on a level surface when the oil is checked.
Location of dipstick and oil filler cap
If the engine is warm , wait for at least 10-15 minutes after the engine has been switched off before checking the oil.
