CAUTION: Take care not to spill gasoline during refueling. Gasolines con\
taining alcohol can cause
damage to painted surfaces, which may not be covered under the New Vehic\
le Limited Warranty.
Do not use gasoline containing methanol (methyl alcohol, wood alcohol)\
. This practice can result in
vehicle performance deterioration and can damage critical parts in the f\
uel system. Such damage may
not be covered under the New Vehicle Limited Warranty.
pg. 4:4 Driving economy
Economical driving does not necessarily mean driving slowly

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. Obs\
erve the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on
the accelerator pedal for the first minutes of operation. A cold engine \
uses more fuel and is subject to
increased wear.
l Whenever possible, avoid using the car for driving short distances. This\
does not allow the engine to
reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Do not exceed speed limit.
l Avoid carrying unnecessary items (extra load) in the car.
l Check tire pressure regularly (check when tires are cold).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc., increase air resistance and there\
by fuel consumption.
l Avoid using automatic transmission kick-down feature unless necessary.
l Avoid using the air conditioning when it is not required. When engaged, \
the air conditioner's
compressor places places an additional load on the engine.
l If your car is equipped with the optional Trip Computer, utilizing the f\
uel consumption modes can
help you "learn" how to drive more economically.

Other factors which decrease gas mileage are:
l Low tire pressure
l Worn or dirty spark plugs
l Incorrect spark plug gap
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment

1) See section "Engine oil" for detailed information.

NOTE: The oil should be changed at these intervals or after 750 hours of\
driving or after 12 months
which ever occurs first. See "Service Reminder indicator",
page 1:5.

2) For services beyond 60,000 miles (96,000 km), consult your "Mainte\
nance records booklet".
3) These intervals may apply, depending on actual driving conditions (\
see page 8:11 for details)
4) For proper functioning of the vehicle and its emission control syste\
m, Volvo recommends that the
timing belt be replaced every 70,000 (112,000 km).

support frame and under the reinforced plate in the spare wheel well. Ta\
ke care not to damage the splash
guard under the engine. Ensure that the jack is positioned so that the c\
ar cannot slide off it. Always use
axle stands or similar structures.


If a two-post hoist is used to lift the car, the front and rear lift arm\
pads should be centered under the
reinforced lift plates on the inboard edge of the sill rail. The positio\
n of these plates is marked with
arrows molded into the bottom of the sill rail.
CAUTION: 850 R turbo models have reduced ground clearance due to the des\
ign of the front spoiler.
Please observe caution when driving the car onto a garage hoist.

Torque exhaust and intake manifold nuts

A loose manifold could alter air/fuel ratio and cause an increase in emi\
ssion and/or poor driveability.

Air cleaner

Replace the air cleaner cartridge with a new one every 30,000 miles (48\
,000 km). The cartridge should
be replaced more often when driving under dirty and dusty conditions. Th\
e filter cannot be cleaned and
therefore should always be replaced with a new one.

Vacuum fittings, hoses and connections

1996 Volvo 850

Unstable idle, misfiring, or poor emission control is often caused by le\
aking vacuum hoses or
connections. Check all vacuum hoses and connections.

Checking and adjusting idle air control system

Your Volvo is equipped with an electronically controlled idle air contro\
l system that requires no
checking or adjustment.

Timing belt

For proper functioning of the vehicle and its emission control systems, \
Volvo recommends that the
timing belt be replaced every 70,000 miles (112,000 km).

Fuel system cap, tank and lines and connections

The effectiveness of the fuel system to contain hydrocarbons is dependen\
t largely on a leak-free system.
Check for proper sealing of the gasoline filler cap which contains "O" r\
ing type seals.

Fuel (line) filter

The fuel line filter is located next to the fuel pump. For proper functi\
oning of the vehicle and its
emission control systems, the fuel line filter should be replaced at 100\
,000 miles (160,000 km). The
filter is replaced as one complete unit. Replace more frequently if cont\
aminated fuel is introduced into
the tank (or if there is reason to suspect that this has occurred).

Charge air cooler (Intercooler)

The B 5234 Turbo engine employs a turbo-compressor to force air into the\
engine inlet manifold and a
charge air cooler to cool the compressed inlet air. The resulting increa\
se in air flow raises pressure in the
intake manifold by approx. 8.7 psi (over atmospheric pressure) and eng\
ine power output by approx. 50
horsepower over that developed by the normally-aspirated engine. The cha\
rge air cooler (which
resembles a radiator) is located between the turbo-compressor and inlet\
manifold.

Evaporative control system

The car is equipped with a gas evaporative control system, which prevent\
s gasoline fumes from being
released into the atmosphere. The system is comprised of an expansion ch\
amber in the fuel tank, a roll-
over valve on the cross member in front of the fuel tank and a charcoal \
canister with a built-in vacuum
valve under the left-front wheel housing. The components are interconnec\
ted by hoses which channel
fuel vapor from the gas tank to the charcoal filter, where it is stored \
until the engine is started and then
drawn into the engine's air intake system.


Crankcase ventilation

The engine is provided with positive crankcase ventilation which prevent\
s crankcase gases from being
released into the atmosphere. Instead, the crankcase gases are admitted \
to the intake manifold and
cylinders.

PCV system

The orifice nipple in the intake manifold and the filter at the end of t\
he PCV hose in the air cleaner
should be inspected every 60,000 miles (96,000 km). Check/replace rubb\
er hoses at the same time. pg. 8:9 Lubrication
