· When starting in the (M)anual position, 3rd gear is the highest gear that may be selected.
NOTE: Kickdown (see previous page) does not function when the transmission is in the manual shift (geartronic)
mode.
W Winter/Wet driving mode - enhanced vehicle traction
· Mode W will only function if the gear selector is in the (D)rive position.
· Press the button at the base of the gear selector to engage/disengage this driving mode (see illustration).
· An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument
panel (see page 23
).
· This mode may be selected for starting/moving off on slippery roads.
pg. 69 Driving economy
Economical driving conserves natural resources
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. Observe the following rules:
· Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
· Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
· Drive carefully and avoid rapid acceleration and hard braking.
· Do not exceed posted speed limits.
· Avoid carrying unnecessary items (extra load) in the car.
· Maintan correct tire pressure. Check tire pressure regularly (when tires are cold).
· Remove snow tires when threat of snow or ice has ended.
· Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· 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.
· If your car is equipped with the optional Trip Computer, utilizing the fuel consumption modes 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
ProCarManuals.com

· 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: (D)rive should be used as often as possible to help improve fuel economy.

Replacing fuses
If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment *
B - Fuse box in the passenger compartment
C - Relays/fuse box in the trunk *
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each
fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you
will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal
wire to see if it is broken. If so, put in a new
fuse of the same color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the passenger
compartment. If fuses burn out repeatedly, have the electrical system inspected by an authorized Volvo retailer.
* The relays and main fuses in the engine compartment and trunk should only be replaced by an authorized
Volvo retailer. You can, however, replace the ordinary fuses if necessary.
pg.89 Fuses in the engine compartment
Relays/fuses in the engine compartment
The relay/fuse box in the engine compartment contains 8 main fuses and space for 21 ordinary fuses. The main fuses
should only be replaced by an authorized Volvo retailer. You can, however, replace the ordinary fuses if necessary.
Be sure to replace a blown fuse with a new one of the same color and amperage (written on the fuse).

Replacing high/low beam headlight bulbs
The headlight bulbs must be replaced from the engine compartment.
CAUTION:
· Do not touch the glass on halogen bulbs with your fingers. Grease, oil or any other impurities can be carbonized onto
the bulb and cause damage to the reflector.
· Be sure to use bulbs of the correct type and voltage.

Charge air cooler (Intercooler)
Turbocharged engines employ a turbocompressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normallyaspirated engine. The charge air cooler (which resembles a radiator)

Replacing spark plugs
The spark plugs should be changed every 30,000 miles (48,000 km). However, city driving or fast highway driving
may necessitate changing after 15,000 miles (24,000 km) of driving. When installing new plugs, be sure to fit the right
type and use correct torque. When changing the plugs, check that the suppressor connectors are in good condition.
Cracked or damaged connectors should be replaced. When changing the spark plugs, clean the terminals and the
