Precautionary steps to observe when towing

Please check with state and local authorities before attempting this typ\
e of towing as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
l Steering must be unlocked.
l Remember that power brake and power steering assists will not be availab\
le when engine is
inoperative. Pedal pressure required is 3 - 4 times above normal and gre\
ater steering effort must be
employed.
l Towing cars equipped with automatic transmission:
-- Gear selector in position N. Check transmission oil level (see secti\
on titled "Transmission oil").
-- Maximum speed: 20 mph (30 km/h).
-- Maximum distance with rear wheels on ground: 20 miles (30 km).

CAUTION!
Do not attempt to start the car by pushing or pulling as damage to catal\
ytic converter can
result.

Jump starting, see section titled "alternator, jump starting".
NOTE:
Refer lo the section regarding "On-
Call"
pg. 49 Tow-truck information
Only use wheel lift or flat bed equipment.
CAUTION:
Sling-type equipment applied at the font will damage radiator and air co\
nditioning lines. It is equally
important not to use sling-type equipment at the rear or apply lifting e\
quipment inside the rear wheels;
serious damage to the rear axle may result.

pg. 50 Trailer hauling
When preparing for trailer hauling, observe the following:

l Use a trailer hitch which meets Federal Safety Standards for rear end co\
llisions (FMVSS 301 -75).
For trailer weights exceeding 2,000 lbs (908 kgs) use only a trailer h\
itch offered as a Genuine Volvo
Accessory.
l Maximum trailer weight recommended by Volvo is 3,300 lbs (1,500 kg). \
However, for cars with automatic transmission, an optional Volvo automat\
ic transmission oil cooler
must be installed when trailer weight exceeds 2,000 lbs (908 kgs). Wit\
h manual transmission, 5th gear
should not be used while towing. Observe legal requirements of the state\
in which the vehicles are
registered.

All Volvo models are equipped with energy absorbing shock mounted bumper\
s. Trailer hitch installation
should not interfere with the proper operation of the bumper system.

WARNING! Bumper-attached trailer hitches must not be used on Volvo's, no\
r should safety chains be
attached to the bumper.
Trailer hitches attaching to the vehicle rear axle must not be used.
WARNING! Never connect a trailer's hydraulic-brake system directly to th\
e vehicle brake system, nor
a trailer's lighting system directly to the vehicle lighting system. Con\
sult your nearest authorized
Volvo dealer for correct installation.

Trailer hauling does not normally present any particular problems, but t\
ake into consideration:
l Recommended hitch tongue load is 110 lbs (50 kgs) for trailer weights \
below 2,650 lbs (1,200 kgs)
and 143-154 lbs (65-70 kgs) for trailer weights above 2,650 lbs (1,20\
0 kgs). However, it must not
exceed 200 lbs (90 kgs).
l For trailer weights between 2,650-3,300 lbs (1,200-1,500 kgs) a top sp\
eed of 50 mph (80 km/h)
should never be exceeded.
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climate or hilly terrain. Use low\
er gear and turn off air
conditioner if temperature gauge pointer enters the red range.
l Avoid overload and other abusive operation.
l Hauling a trailer affects handling, durability and economy.

l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check
and observe State regulations).
l More frequent vehicle maintenance is required.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Increase tire pressure to recommended full-load pressure. See section 'W\
heels and Tires."
Note: Refer to section entitled "Automatic transmission" for additional \
trailer hauling
tips.
Warning: Do not drive with trunk lid or tailgate
open!

Poisonous exhaust gases may enter via the open trunk lid or tailgate. (\
This is especially true for wagon
models.)
If the trunk lid or tailgate for any reason must be open, proceed as fol\
lows:
l Close the windows.
l Set the heating system controls for floor and defroster to max. and the \
blower to full speed (4). See
section titled "Heating and Ventilation".

Handling, roadholding

Vehicle load, tire design and inflation pressure are important for prope\
r handling. Therefore check that
the tires are inflated to the recommended pressure according to the vehi\
cle load.
Loads should be distributed so that capacity weight or maximum permissib\
le axle loads are not
exceeded.
It is recommended to use tires of the same make and dimensions on all fo\
ur wheels.

Warning: Do not mix radial ply and bias ply tires as this will adversely\
alter the vehicle handling
characteristics.

Roof rack

Permanent and removable roof racks are available from Volvo Accessories.\

l Observe the following points when in use.
l Avoid point loads. Distribute the load evenly.
l Place the heavy cargo at bottom of load.
l Observe that center of gravity and handling are influenced by the load w\
eight.
l Increasing load size increases wind resistance.
l Anchor the cargo correctly with a cord.
l Drive carefully. Avoid rapid starts, heavy cornering and heavy braking. \
l Max. roof load is 220 lbs (100 kg); use a root rack with a sufficient \
load rating.
pg. 51 Automatic transmission, Brake system
The following "Special Tips" apply to cars with automatic transmission

l For steep hills and when driving for prolonged periods at low speeds, po\
sition 1 should be selected.
Avoid, however, repeated changes since this can cause overheating of the\
transmission oil. For driving
on mountain roads with long persistent uphill gradients, select position\
2.
l When negotiating long, steep, downhill slopes, position 1 should be sele\
cted and position 2 for less
severe inclines, in order to obtain the best possible engine braking eff\
ect.
Do not hold the car stationary on an incline by using the accelerator pe\
dal. Instead, engage the hand
brake. This prevents the transmission oil from becoming overheated.
l 4th gear must be disengaged when hauling a trailer!
l If an additional transmission oil cooler is installed you can haul a tra\
iler with the overdrive engaged.
See next "special tip".
l When driving with heavy trailers, it is recommended that an additional o\
il cooler be installed. This
applies especially when driving under severe conditions e.g. mountain dr\
iving or prolonged driving at
high speeds without breaks. The additional oil cooler is available as a \
genuine Volvo accessory.
Regarding oil change, see section titled "Transmission oil".

Moisture on brake discs and brake pads affects braking.

Driving in rain and slush or passing through a normal car wash can cause\
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 d\
riving in rain or slush.
This will remove the water from the brakes.
This should also be done after washing or starting in very damp weather.\


If the brake power assist does not 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 the\
car is increased 3- 4 times.
The brake pedal feels stiff and hard.
Disc brake noise: A slight-to-moderate amount of disc brake "squeal" is \
considered normal.

Air dam (front spoiler)

A non-factory air dam can negatively influence the normal flow of coolin\
g air to the front wheel brakes.
(See section titled "Wheels and Tires").

If one of the brake circuits should malfunction the red warning light wi\
ll come on



(See section titled "Warning Lights".)
The pedal stroke increases slightly and the pedal feels softer but the p\
edal pressure required does not
increase noticeably.
If the light comes on while driving and the brake pedal can be depressed\
further than normal, it is an
indication that one of the brake circuits is not functioning. Stop immed\
iately, open engine hood and
check brake fluid level.
Reservoir empty: do NOT drive. Tow car to shop for check/repair of brake\
system. Reservoir not empty:
proceed immediately and with caution to a Volvo dealer for an inspection\
of the brake system.

Severe strain on the brake system

The brakes will be subject to severe strain when driving in mountains or\
hilly areas. The speed is usually
low which means that the cooling of the brake is less efficient than whe\
n 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 and let the engine help with the brakin\
g. A good rule is to use the same
gear downhill as would be used ascending the same grade. For vehicles wi\
th automatic transmission use
position 2, or in some cases, 1.

pg. 52 Catalytic Converter
Catalytic Converter Cautions


l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly involving the electrical,
fuel or ignition systems, may cause unusually high converter temperature\
s. Do not continue to operate
your vehicle it you detect engine misfire, noticeable loss of power or o\
ther unusual operating conditions,
such as engine overheating or backfiring. A properly-tuned engine will h\
elp in avoiding malfunctions
that could damage the Catalytic Converter.

l Remember that tampering with or unauthorized modifications to the engine\
or the vehicle may be
illegal and can cause catalyst or exhaust system overheating. This inclu\
des:
-- Altering fuel injection settings or components.
-- Adjusting ignition timing beyond specified limits.
-- Altering emission system components or location or removing component\
s.
-- Use of leaded fuel.

WARNING: 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 t\
o ignite under certain wind
and weather conditions.

l Excessive starter cranking (in excess of one continuous minute) with a\
n intermittently firing or
flooded engine, can cause catalyst or exhaust system overheating. This a\
lso applies to lengthy pushing or
towing of vehicle to start (manual transmissions only). Do not attempt\
to start a car with automatic

Changing coolant

Every two years or 30,000 miles (48,000 km) the cooling system should \
be drained, flushed and refilled.
Remove the expansion tank cap. Open the drain cock on right side of the \
engine block and disconnect
the lower radiator hose.

Fill coolant through the expansion tank.
The heater controls should be fully open when draining and filling.
Add coolant until the level is up to the MAX mark or slightly above.

Start engine and run until hot. Check the cooling system connections for\
tightness. Also re-check the
coolant level. Capacity: 9.9 US qts. = 9.4 liters (manual transmission \
models); 9.7 US qts = 9.2 liters

This temperature is obtained when driving for about 30 minutes.
At oil temperature above + 195°F ( + 90°C), the level may be abo\
ve the MAX mark.
Note!
The engine should be idling when checking transmission fluid
level.

Check the oil level as follows:
Park the car on level surface with the engine idling.
Slowly move the selector lever through all the gear positions and then t\
o position P. Wait 2 minutes
before checking the oil level. As the illustration shows, the dipstick h\
as a "Cold" and a "warm" side.
