cold-weather oil for hard driving or in warm
weather. See section "Engine oil" for more
information.
l The load placed on the battery is greater during
the winter since the heater, windshield wipers,
lighting etc. are used more often. Moreover, the
capacity of the battery decreases as the
temperature drops. In very cold weather, a poorly
charged battery can freeze and be damaged. It is
therefore advisable to check the state of charge
more frequently and spray an anti-rust oil on the
battery posts.
l Volvo recommends the use of snow tires on all
four wheels for winter driving - see section
"Wheels and tires".
l To prevent the washer reservoir from freezing,
add washer solvents containing antifreeze. This is
important since dirt is often splashed on the
windshield during winter driving, thus requiring
frequent use of the washers and wipers.

*In position D, the gearbox starts in third gear and
changes up to fourth gear.
*In position 3, second gear is locked and there is
no change up to third gear. In position L, first gear
is locked.
*These positions always offer the kick-down
feature.
Long distance trip pg. 70
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer
before driving long distances. Your retailer will also be able to supply\
you with bulbs, fuses, spark plugs and wiper blades for your use in the \
event that problems occur.
If you prefer to check the car yourself, please note the following:
l Check that the engine runs smoothly and that fuel consumption is
normal.
l Check engine oil, coolant levels, and for possible fuel leakage.
l Check transmission oil level and rear axle for leakage.
l Check condition of drive belts.
l Check state of charge of battery.
l Examine tires carefully (the spare tire as well), and replace those
that are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be
checked by your Volvo retailer only.
l Check all lights, including high beams.

Changing a wheel
On sedans the spare wheel, jack and toolbag are located in the trunk, be\
neath the carpet. The jack must be completely retracted to fit into the holder.
On wagons, the spare tire and the jack are located beneath the floor mat\
in the large storage bin. Always secure the spare tire and the jack to prevent them from rattling.
l Remove the wheel cap, using the screwdriver in the tool kit.
l With the car still on the ground, use the box wrench from the tool kit t\
o loosen the wheel nuts 1/2 - 1 turn. Turn the nuts counterclockwise to loosen.
NOTE:
To avoid excessive wear and the necessity of rebalancing, mark and reins\
tall wheels in same location and position as before removal. To lessen the chance of imbalance, each
wheel hub is equipped with a guide stud to ensure that a removed wheel c\
an be reinstalled in its original position (as when changing over to winter tires/wheels).
Wheel changing (cont.) pg. 79
WARNING!
l The jack attachment must engage the bar in the jack attachment (A). Th\
e car's weight must not rest on the jack's attachment (B).
l Be sure the jack is on a firm, level, non-slippery surface.
l Never allow any part of your body to be extended under a car supported b\
y a jack.
l Use the jack intended for the car when replacing a wheel. For any other \
job, use stands to support the end of the car being worked
on.
l Apply the parking brake, select position P (automatic transmission). \
l Block the wheels standing on the ground. Use rigid wooden blocks or larg\
e stones.
l The jack should be kept well-greased.

Oil quality
Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection,
consult with your authorized Volvo retailer for
recommended oils. Oil with a different quality
rating may not provide adequate engine
protection.
Synthetic oils complying with oil quality
requirements are recommended for: driving in
areas of sustained temperature extremes (hot or
cold), when towing a trailer over long distances or
for prolonged driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.
NOTE:SAE 15W/40 should only be used in
extreme operating conditions such as trailer
towing in sustained ambient temperatures over
104° F (40° C). However, SAE 10W-30 synthetic
oil would be a better alternative in such
conditions.
SAE 15W-40 should not be used under normal
operating conditions.
