· Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and  the windows down. 
· Utilizing the fuel consumption modes in the Trip Computer can help you "learn"  how to drive more economically.
Other factors  which 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.
NOTE : The automatic  transmission's ( D)rive position should be  used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires 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  will adversely alter vehicle handling characteristics. Maintain correct tire
pressure. 
pg. 61 Starting the engine
Starting and stopping
1. Fasten the seat belt.WARNING!
Before starting, check that the seat, steering wheel and  mirrors  are adjusted properly. Make sure the brake pedal can
be  depressed  completely.  Move the seat closer if necessary.  Refer to section "front seats".
2. Apply the parking brake, if not already  set. The gear selector  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 up to 5 seconds. Release the key  as soon as the engine starts. If the engine fails to start, repeat  step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator  pedal halfway and  turn the key  to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from  the (P)ark position, the ignition key  must  be  in position II and  the brake pedal
must  be  depressed.
See  page 95
 for instructions on manually  releasing the SHIFTLOCK  system.
NOTE: 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 from  the ignition switch.
5. Select  the desired gear. The gear engages after a  slight delay which  is especially noticeable when selecting R.

If accessory,  aftermarket or "custom" tires and  wheels are installed and  are of a  size different  than the original tires
and  wheels, chains in some cases CANNOT be  used. Sufficient  clearances between chains and  brakes, suspension and
body components must  be  maintained.
· Some strapon  type chains will interfere  with brake components and  therefore CANNOT be  used.
Consult your Volvo retailer for additional snow chain information.
Snow tires, studded tires *
Tires for winter use:
Owners who live in or  regularly  commute  through  areas with sustained  periods of snow or  icy driving
conditions are strongly advised to fit  suitable winter tires to help retain the highest degree of traction.
It is important to install  winter tires on all four wheels to help retain traction during cornering, braking, and
accelerating. Failure to do so could reduce traction to an  unsafe level  or adversely affect handling. Do not mix tires of
different  design as this  could also negatively affect overall tire road grip. Volvo recommends  195/55 R15 winter tires
on 15" steel rims  on all S/V 40 models.
Winter tires wear  more quickly on dry roads in warm weather. They should be  removed when the winter driving
season has ended.
Studded tires  should be  runin 300600 miles (5001000 km) during which  the car should be  driven as smoothly as
possible to give the studs the opportunity to seat properly in the tires. The car tires should have the same rotational
direction throughout their entire lifetime. In other words,  if you wish to rotate the wheels, make sure that the same
wheels are always on the same side of the car.
NOTE:  Please consult state or provincial regulations  restricting the use of studded winter tires before installing such
tires.
CAUTION:
· Check local  regulations  regarding the use of snow chains before installing.
· Always follow the chain manufacturer's installation  instructions carefully. Install chains as tightly as possible and
retighten periodically.
· Never  exceed the chain manufacturer's specified maximum speed limit. (Under no circumstances should that limit be
higher than 30 mph (45 km/h).
· Avoid bumps, holes or sharp turns when driving with snow chains.
· The handling of the vehicle can be  adversely affected when driving with chains. Avoid fast  or sharp turns as well as
locked wheel braking.
