torque VOLVO S40 2005 Owners Manual

To return to the (D)rive position from M , move the gear selector to the left.
While driving
If you select the M position while driving, the gear that was being used in the (D)rive position will also initially be
selected in M position.
Move the gear selector forward (toward "+") to shift to a higher gear or rearward (toward "-") to shift to a lower
gear.
If you hold the gear selector toward "-", the transmission will downshift one gear at a time and will utilize the
braking power of the engine. If the current
pg. 109 Automatic transmission - Geartronic
speed is too high for using a lower gear, the downshift will not occur until the speed has decreased enough to allow the
lower gear to be used.
If you slow to a very low speed, the transmission will automatically shift down.
W - Winter/Wet driving mode - enhanced vehicle traction
Mode W reduces torque at the wheels, which helps improve traction when starting off on a slippery surface.
Once underway, turn off mode W to improve vehicle performance and fuel economy.
Mode W will only function if the gear selector is in the ( D)rive position.
Press the button near the base of the gear selector to engage/disengage this driving mode. The indicator light in the
button will light up when the function is engaged.
Automatic transmission - adaptive system
The automatic transmission is controlled by an adaptive control system that constantly monitors the way in which the
transmission functions. It senses and adapts each gear shift for optimal performance.
Cold starts (turbo engines)
When driving before the engine has reached its normal operating temperature, the transmission will shift up at slightly
higher engine speeds to heat the three-way catalytic converter as quickly as possible.
Kickdown
Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An
upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly.
Kickdown can be used for maximum acceleration or when passing at highway speeds.
NOTE: The gear selector must be in the D (Drive) position for kickdown to function.
Shiftlock override
Shiftlock prevents the gear selector from being moved out of Park unless the ignition key is in position II and the
brake pedal is depressed.
In certain cases it may be necessary to move the gear selector from the Park position manually, for example if the
battery is discharged.

driving in mountainous areas.
American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
The upper section describes the oil's performance level.
The center identifies the oil's viscosity.
The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in
comparison to a reference oil.

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 normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
pg. 189 Electrical system
General information
