2002 VOLVO V70 fuel pressure

In addition to continuous environmental refinement of conventional gasoline-powered internal combustion engines,
Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment.
To reduce your vehicle's environmental impact, you can:
· Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires
· Follow the recommended maintenance schedule
· Drive at a constant speed
· See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates, or stays on after the vehicle has started
· Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
· When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment
Prem-Air
On the surface of the radiator in the engine compartment, there is a special coating called Prem-Air. Prem-Air works
as a catalytic converter, converting most of the ozone passing through the radiator into oxygen, thereby reducing
harmful ground-level ozone.

Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
pg. 82 Refueling
Refueling
The fuel tank is designed to hold approximately 21.1 US gal. (80 liters)* with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat
less than the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid
vapor pressure" characteristics, and terrain can affect the fuel pump's ability to supply the engine with an adequate
supply of fuel. Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the
fuel warning light comes on.
Fuel filler door
Press the button on the light switch panel (see illustration on page 32) when the car is at a standstill to unlock the fuel
filler door. Please note that the fuel filler door will remain unlocked until the car is driven again at a speed of over
approximately 5 mph (8km/h). An audible click will be heard when the fuel filler door relocks.
If you intend to leave your car while it is being refueled, this features enables you to lock the door/tailgate while
leaving the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refueling. The central locking button does not lock the
fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed after refueling. Open the fuel filler cap slowly
during hot weather conditions.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 126
for
ProCarManuals.com

W Winter/Wet driving mode -enhanced vehicle traction
Mode W will function only if the gear selector is in the (D)rive position.
Press the button at the base of the gear selector to engage/disengage this driving mode (see illustration).
An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument
panel (see page 25
).
This mode may be selected for starting/ moving off on slippery roads.
pg. 89 Driving economy
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
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.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the conditioner's compressor places an
additional load on the engine. However, at higher 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:
Worn or dirty spark plugs
Incorrect spark plug gap
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 Service intervals.
ProCarManuals.com

NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kick -down" to help improve fuel economy. Vehicles equipped with manual transmissions should use fifth gear at
highway speeds. At other times, choose the highest gear that still allows smooth acceleration.
Weight distribution affects handling
At the specified curb weight your car 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 on the rear of
the vehicle (e.g., heavily loaded (max. 220 lbs, 100 kg) cargo area or when towing a trailer, the less the tendency to
understeer.
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 "Tire pressure" section. Loads should be distributed so
that capacity weight or maximum permissible axle loads are not exceeded.
pg. 90 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed: Do not drive for prolonged periods at engine speeds
above 4500 rpm if you are towing a trailer in hilly terrain. Reduce speed when towing a trailer up long, steep inclines.
The risk of overheating can be reduced by switching off the air conditioning system for a short time. Do not let the
engine idle unnecessarily for prolonged periods. Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be taken:
Switch off the air conditioning system.
Pull off the road, away from traffic, stop the car and put the gear selector into neutral.
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see page 127
and 130 for information on checking and topping-up the coolant level.
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 1 foot (300 mm). See the flood warning on page 7
.

pg. 104 Wheels and tires
General information
Your vehicle is equipped with tires according to the tire information label on the inside of the fuel filler door.
The following is an example of a tire designation code: 225/55 R16
225 = tire width in mm.
55 = tire profile. This is the relationship (in percent) between the section height and width of the tire.
R = radial tires.
16 = diameter in inches.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces. Certain models are
equipped with "all-season" tires, which provide a somewhat higher degree of road holding on slippery surfaces
than tires without the "all-season" rating. However, for optimum road holding on icy or snow covered roads - we
recommend suitable winter tires on all four wheels . When replacing tires, be sure that the new tires are the same
dimensions, type (radial) and preferably from the same manufacturer, on all four wheels. Do not use bias ply tires.
Otherwise there is a risk of altering the car's roadholding and handling characteristics.
NOTE: When storing wheel/tire assemblies (e.g. snow tires and wheels), either stand the assemblies upright, or
suspend them off the ground. Laying wheel/tire assemblies on their sides for prolonged periods can cause wheel and/or
tire damage.
Wear indicator
ProCarManuals.com

The tires have wear indicator strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate that the tire should be replaced.
Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain or snow.
To improve tire economy:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
Drive smoothly: avoid fast starts, hard braking and tire screeching.
Tire wear increases with speed.
Correct front wheel alignment is very important.
Unbalanced wheels impair tire economy and driving comfort.
Volvo does not recommend rotating the tires. However, if tires are rotated, they must be kept on the same side of the
car so that they revolve in the same direction as before rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
CAUTION: Cars equipped with All Wheel Drive
The car must not be driven with wheels of different dimensions/ specifications or with a spare tire other than the one
that came with the car. The use of different size wheels can seriously damage your car's transmission.
Driving with the temporary spare tire at speeds above 50 mph (80 km/h) can reduce the service life of transmission
components. Do not drive farther than 50 miles (80 km) on a temporary spare tire.
When one or more tires is replaced, the new tire(s) should be mounted on the front wheels. The tires with the least
amount of tread should be mounted on the rear wheels.
pg. 105 Wheels and tires - All Wheel Drive vehicles
Types of Tires
Always drive on tires of identical brand, size, construction (radial), tread pattern, load-, speed-, traction-, temperature-,
and treadwear rating. Never drive on mixed tires, except for brief periods when the temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and inflation pressures are shown on the tire
pressure label located inside the fuel filler door.
CAUTION:
Failure to always drive on properly inflated, identical tires of correct dimensions may result in a circumference
difference between tires on the front and rear axles. This will cause excessive tire wear and may damage the
transmission and all-wheel-drive system.
ProCarManuals.com

Vehicle loading
The tires on your Volvo should perform to specifications at all normal loads when inflated as recommended on the tire
informa-tion label. The label is located on the inside of the fuel filler door. The label lists both tire and vehicle design
limits. Do not load your car beyond the load limits indicated.WARNING!
Improperly inflated tires will reduce tire life, adversely affect vehicle handling and can possibly lead to failure
resulting in loss of vehicle control without prior warning.
Temporary Spare
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/80 R17 (T135/90 R17
on the Cross Country).
At the recommended tire pressure shown on the inside of the fuel filler door, the tire may be used as a temporary
replacement for a front or rear tire.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible by a standard tire. Road holding and handling may be
affected with the "Temporary Spare" in use. Do not exceed 50 mph (80 km/h). Do not drive farther than 50 miles
(80 km) on a temporary spare tire.
All Wheel Drive models: Driving with the "Temporary Spare" at speeds above 50 mph (80 kph) can lead to
excessive wear on transmission components.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
NOTE: Certain models may be equipped with a full-size spare tire. When used, it should be inflated to the same
pressure as the tire it is replacing.
