Some of the above mentioned items and others are checked at the standard\
Maintenance Service
intervals.

NOTE: ( D )rive or 5th gear (manual transmissions) should be used as\
often as possible to help improve
fuel economy. pg. 4:5 Starting the engine
Starting and stopping

1. Fasten the seat belt.
WARNING! Before starting, check that the seat and steering wheel are adj\
usted properly. Make sure
the brake pedal can be depressed completely. Move the seat closer if nec\
essary. Refer to section "front
seats".

2. Apply the parking brake, if not already set. The gear selector ( aut\
omatic transmission ) is locked in
the ( P )ark position ( SHIFT LOCK ).

3. Without touching the accelerator pedal , turn the ignition key to the\
starting position. Allow the starter
to operate for 5-10 seconds (turbo: 10 seconds). Release the key as so\
on as the engine starts. If the
engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 m), depress the accel\
erator pedal halfway and turn the
key to the starting position. Release the accelerator pedal slowly when \
the engine starts.

4. To release the gear selector from the (P)ark position (automatic t\
ransmission), the ignition key must
be in position II and the brake pedal must be depressed.
See page 6:18 for instructions on manually
overriding the SHIFTLOCK system.

Do not race a cold engine immediately after starting. Oil flow may not r\
each some lubricating points fast
enough to prevent engine damage.

NOTE: (Automatic transmission only)

Your car is equipped with a KEYLOCK system. When the engine is switched \
off, the gear selector must
be in the ( P )ark position before the starting key can be removed fro\
m the ignition switch.

5. Select desired gear. The gear engages after a slight delay (automati\
c transmission) which is especially
noticeable when selecting R.
CAUTION: (Automatic transmission only) The engine should be idling; ne\
ver accelerate until after
you feel the gear engage! Too rapid acceleration immediately after selec\
ting a gear will cause harsh
engagement and premature transmission wear.

NOTE: Selecting P or N (automatic transmission) when idling at a stand\
still for prolonged periods of
time will help prevent overheating of transmission oil.
WARNING! Always place the gear selector (automatic transmission) in Pa\
rk and apply the parking
brake before leaving the vehicle. Never leave the car unattended with th\
e engine running.
Always open the garage doors fully before starting the engine inside a g\
arage to ensure adequate
ventilation. The exhaust gases contain carbon monoxide, which is invisib\
le and odorless but very
poisonous.
TURBO CAUTION:
Never race the engine immediately after starting. Oil flow may not reach\
some lubricating points fast
enough to prevent engine damage.
Do not race the engine just prior to switching off!

Hydraulic valve lifters

This engine features hydraulic valve lifters which means that valve clea\
rance is adjusted automatically.
It is possible that the valve lifters will produce a ticking sound for t\
he first few seconds after the engine
is started, while the oil pressure is increasing.
If the car has not been used for a long period of time, this ticking sou\
nd may last for up to 15 minutes.
This is entirely normal.
Do not exceed 300 rpm until the ticking sound disappears.

P (Park)

Use this position when starting the engine or parking the car.
Never use P while car is in motion.
The parking brake should also be used when parking on grades.
The gear selector is mechanically locked in the P position (Shift lock)\
. To release the selector, start the
engine and depress the brake pedal. If it is necessary to manually relea\
se the gear selector,
see page 6:18
for instructions.

CAUTION:
l Never select P or R while the car is in motion.
l When initially selecting positions D, 3, L or R, your right foot should \
press firmly on the brake
pedal to ensure that the car is standing still with the engine idling.
l The gear selector should not be downshifted to L at speeds above 75 mph \
(125 km/h).*
* Always observe posted speed limits.
WARNING! Never leave the car when the engine is running. If, by mistake,\
the gear selector is moved
from P the car may start moving.

R (Reverse)

Never engage R while is moving forward.

N (Neutral)

Neutral = no gear is engaged. Use the parking brake. The engine can be s\
tarted with the gear selector in
this position.

D (Drive)

D is the normal driving position and should be used as often as possible\
to help improve fuel economy.
When modes E or S are selected, upshift and downshift of the forward gea\
rs occur automatically and are

WARNING! Do not remove the coolant expansion tank
cap.

See "Coolant" to check and top-up the coolant level if necessary.
CAUTION: Drive slowly and carefully if going through standing water (i.\
e. flooded roadways, etc.).
Damage to engine could result if excess water is ingested through the ai\
r intake system.
Never drive the vehicle in water deeper than 1 foot (300 mm).
See the flood warning on page 3:7.
WARNING! Do not drive with trunk lid or tailgate open!
Poisonous exhaust gases may enter via the trunk lid or tailgate.
If the trunk lid/tailgate must be kept open for any reason, proceed as f\
ollows:
l Close the windows.
l Set the ventilation system control to air to floor, windshield and side \
windows and blower control to
its highest setting.
Electrical system

When replacing the battery or when carrying out work involving the elect\
rical system, the following
should be observed:
l A battery connection to the wrong terminal will damage the diodes. Befor\
e connections are made,
check the polarity of the battery with a voltmeter.
l If booster batteries are used for starting, they must be properly connec\
ted to minimize the risk of the
diode being damaged. For correct connection, see "Jump starting" section\
.
l Never disconnect the battery circuit (for example, to replace the batte\
ry) while the engine is running,
as this will immediately ruin the generator. Always make sure that all t\
he battery connections are
properly tightened.
l If any electrical-welding work is performed on the vehicle, the ground l\
ead and all the connecting
cables of the generator must be disconnected and the welder cables place\
d as near the welding point as
possible.
l The radio must be turned off before the battery is disconnected.
l The anti-theft code must be re-entered before the radio will function pr\
operly.
l The electrical system in your car is designed to accommodate Volvo acces\
sories. It also has an
accessory connector beneath the dashboard on the driver's side.

Weight distribution affects handling

At the specified curb weight your car has a tendency to understeer, whic\
h 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 p\
roperties can alter with the
vehicle load. The heavier the load in the trunk (max. 220 lbs, 100 kg)\
, the less the tendency to
understeer.

Handling, roadholding

Vehicle load, tire design, and inflation pressure, all affect vehicle ha\
ndling. 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 permissib\
le axle loads are not
exceeded.
WARNING! It is recommended that tire of the same make and dimensions be \
used on all four wheels
(including the use of snow tires). Do not use bias ply tires as this w\
ill adversely alter vehicle handling
characteristics.

1996 Volvo 850

Roof racks are available as Volvo accessories. Observe the following poi\
nts when is use:
l Avoid single-point loads. Distribute the load evenly.
l Place heavier cargo at bottom of load.
l Observe that center of gravity and handling are influenced by load weigh\
t.
l Increasing load size increases wind resistance and, thus, adversely affe\
cts fuel economy.
l Anchor the cargo correctly with appropriate tie-down equipment.
l Drive carefully. Avoid rapid starts, fast cornering and hard braking.
l Max. roof load is 220 lbs. (100 kg) when Volvo approved removable roof\
racks are attached to the
points indicated in the illustration. For permanent roof racks, check th\
e manufacturers weight
specifications.

WARNING! An extra mat on the driver's floor can cause the accelerator pe\
dal to catch. Check that the
movement of the accelerator pedal is not impeded. Not more than one prot\
ective floor covering may be
used at one time.

pg. 4:13 Vehicle towing information
Only use flat bed equipment.

CAUTION:
l Sling-type equipment applied at the front will damage radiator and air c\
onditioning lines.
l It is equally important not to use sling-type equipment inside the rear \
wheels: serious damage to the
rear axle may result.

The car should be towed with the rear wheels on the ground, if at all po\
ssible. If it is absolutely
necessary to tow the vehicle with the front wheels on the ground, please\
refer to the towing information
on the previous page.

* If wheel lift equipment must be used, please use extreme caution to he\
lp avoid damage to the car.

WARNING!
Do not use the towing eyelets on the car to pull the car up onto a flat \
bed tow
truck.

WARNING!
l To reduce the possibility of explosion, never expose battery to open fla\
me or electric spark.
l Do not smoke near battery.
l Batteries generate hydrogen gas which is flammable and explosive.
l Battery fluid contains sulfuric acid. Do not allow battery fluid to cont\
act eyes, skin, fabrics or
painted surfaces. If contact occurs, flush affected area immediately wit\
h water. Obtain medical
attention immediately if eyes are affected.
Failure to follow the instructions for jump starting can lead to persona\
l injury.
pg. 4:15 Three-way catalytic converter

Three-way catalytic converter cautions

l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or distributor ignition systems, may cause unusually high three-way\
catalytic converter
temperatures. Do not continue to operate your vehicle if you detect engi\
ne misfire, noticeable loss of
power or other unusual operating conditions, such as engine overheating \
or backfiring. A properly tuned
engine will help avoid malfunction that could damage the three-way catal\
ytic converter.
l Do not park your car over combustible materials, such as grass or leaves\
, which can come into contact
with the hot exhaust system and cause such materials to ignite under cer\
tain wind and weather
conditions.
l Excessive starter cranking (in excess of one minute), with an intermit\
tently firing or flooded engine,

can cause three-way catalytic converter or exhaust system overheating.
l Remember that tampering or unauthorized modification to the engine or th\
e vehicle may be illegal
and can cause three-way catalytic converter or exhaust system overheatin\
g. This includes:
- Altering fuel injection settings or components.
- Adjusting distributor ignition timing beyond specified limits.
- Altering emission system components or location or removing components\

- Repeated use of leaded fuel.

NOTE: Unleaded fuel is required for cars with three-way catalytic conver\
ters. A label on the instrument
panel and inside fuel tank filler door will remind owners and filling st\
ation attendants of this
requirement.

Important! It is unlawful to dispense leaded fuel into any vehicle label\
ed "unleaded gasoline only".
pg. 4:16 Brake system


Anti-lock Brake System (ABS)

If the warning lamp lights up there is a malfunction of the ABS system (\
the standard braking system will
however function) and the vehicle should be driven to a Volvo retailer \
for inspection. The Anti-lock
Braking System (ABS) helps to improve vehicle control (stopping and s\
teering) during severe braking
conditions by limiting brake lock-up. When the system "senses" impending\
lock-up, braking pressure is
automatically modulated in order to help prevent lockup, which could lea\
d to a skid.
The system performs a self-diagnostic test when the vehicle first reache\
s a speed of approximately 12
mph (20 km/h). The brake pedal will pulsate several times and a sound \
may be audible from the ABS
control module. This is normal.
To obtain optimal effect from the ABS system, constant pressure should b\
e kept on the brake pedal
while the system is modulating the brakes. Do not pump the brake pedal. \

The switching of the ABS modulator will be audible and the brake pedal w\
ill pulsate at this time. Please
be aware that ABS does not increase the absolute braking potential of th\
e vehicle. While control will be
enhanced, ABS will not shorten stopping distances on slippery surfaces. \

Brake circuit malfunction

If one of the brake circuits should malfunction, the red warning light w\
ill come on, the pedal stroke
increases slightly, the pedal feels softer and extra pressure is require\
d for normal braking. If the light
comes on while driving or braking, stop immediately and check the brake \
fluid level in the reservoir.
WARNING! If the fluid level is below the MIN mark in either section of t\
he reservoir: DO NOT
DRIVE. Tow the car to a Volvo retailer and have the brake system checked\
and repaired.

Moisture on brake discs and brake pads affects braking.

Driving in rain and slush or passing through an automatic car wash can c\
ause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the\
pedal is depressed. To avoid
such a delay when the brakes are needed, depress the pedal occasionally \
when driving through rain,
slush etc. This will remove the water from the brakes. Check that brake \
application feels normal! This
should also be done after washing or starting in very damp weather.

Severe strain on the brake system

The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. The speed
is usually low which means that the cooling of the brakes is less effici\
ent than when driving on level
roads. To reduce the strain on the brakes it is advisable not to use the\
brakes excessively. Instead, shift
into a lower gear, position 3 or in some cases, L(automatic transmissio\
n) and let the engine help with the
braking. Do not forget that, if you are towing a trailer, the brakes wil\
l be subjected to greater load than is
normal.

If the brake power-assist does function

The power assist to the brakes functions only when the engine is running\
. When the car is moving
without the engine running, the brake pedal pressure required to stop th\
e car is increased by 3-4 times
and the brake pedal feels stiff.
