Functions
NOTE
If a warning message appears while you are using the trip computer, this message must be acknowledged in order to
return to the trip computer function. Acknowledge a message by pressing READ .
To change the unit of measure specified for distance and speed, contact an authorized Volvo workshop.
Average speed
The system calculates the average speed from the last resetting. Reset using RESET .
Current speed in mph (Canadian models only)

This function provides the driver with an instantaneous conversion of the car's current speed from km/h to mph.
Current speed in km/h (U.S. models only)
This function provides the driver with an instantaneous conversion of the car's current speed from mph to km/h.
Current fuel consumption (Instantaneous)
Current fuel consumption is calculated every second. The information on the display is updated every few seconds.
When the vehicle is stationary, "----" appears on the display.
Average fuel consumption
The average fuel consumption since the last reset. Reset using RESET.
Driving distance on current fuel reserve
The calculation is based on the average fuel consumption over the last 20 miles ( 30 km) and the remaining usable fuel
in the tank. This shows the approximate distance that can be driven with the fuel quantity remaining in the tank. When
the driving distance on the current fuel reserve is less than 12 miles ( 20 km), " ---- miles to empty tank" is shown on
the display.
NOTE
The actual distance that can be driven on the usable fuel remaining in the tank may be influenced by a change in
driving style.

Compass
Operation
The upper right corner of the rearview mirror has an integrated display that shows the compass direction in which the

vehicle is pointing. Eight different directions are shown with the abbreviations: N (north), NE (north east), E (east), SE
(southeast), S (south), SW (southwest), W (west) and NW (northwest).
The compass is displayed automatically when the vehicle is started or in ignition mode II . To switch the compass
on/off use a pen or similar object and press in the button on the rear side of the mirror.
Calibration
The compass may need to be calibrated if, for example, the vehicle is driven into a new magnetic zone. The characters
CAL are shown in the mirror's display if calibration is necessary.
1. Stop the vehicle in a large open area, away from traffic.
2. Start the vehicle.
3. Using a pen or similar object, press and hold the button on the rear side of mirror until CAL is shown again (after
approx. 6 seconds).
4. Drive as usual. CAL disappears from the display when calibration is complete. Alternative calibration method:
Drive slowly in a circle at a speed of no more than 5 mph (8 km/h) until CAL disappears from the display when
calibration is complete.
Selecting a magnetic zone
The earth is divided into 15 magnetic zones. The correct zone must be selected for the compass to work correctly.
1. Put the ignition in mode II .
2. Using a pen or similar object, press and hold the button on the rear side of mirror for at least 3 seconds. The number
for the current area will be shown.
3. Press the button repeatedly until the number for the required geographic area (1-15) is shown.

Stability system
Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of functions designed help reduce
wheel spin, counteract skidding, and to generally help improve directional stability.
CAUTION
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)
This function is designed to help reduce wheel spin by transferring power from a drive wheel that begins to lose
traction to the wheel on the opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and cannot be switched off.
Active Yaw Control (AYC)
This function helps maintain directional stability, for example when cornering, by braking one or more of the wheels if
the vehicle shows a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and cannot be switched off.
Spin control (SC)
The spin control function is designed to help prevent the drive wheels from spinning while the vehicle is accelerating.
Under certain circumstances, such as when driving with snow chains, or driving in deep snow or loose sand, it may be
advisable to temporarily switch off this function for maximum tractive force.
WARNING
The car's handling and stability characteristics will be altered if the spin control function has been disabled.
Operation

Temporarily switching off Spin control
1. Turn the thumbwheel
until the DSTC menu is shown.
2. Hold down the RESET button
to toggle between DSTC SPIN CONTROL ON or OFF .
Messages in the information display
DSTC Temporarily OFF - system function has been temporarily reduced due to high brake disc temperature. The
function is activated automatically when the brakes have cooled.
DSTC Service required - the system has been disabled due to a fault. If this occurs:

Stability system
1. Stop the vehicle in a safe place and turn off the engine.
2. Restart the engine.
If the message remains when the engine is restarted, drive to an authorized Volvo workshop to have the system
inspected.
Symbols in the instrument panel
If the symbols
and are displayed at the same time, read the message in the information display.
If the symbol
appears alone, it may appear as follows:
If the symbol flashes, this indicates that the stability system is actively functioning to help counteract wheel spin
and/or a skid.
If the symbol remains on for approximately 2 seconds after the engine has been started, this indicates that the system
is performing a self -diagnostic test.
WARNING
The stability system is intended to help improve driving safety. It supplements, but can never replace, the driver's
judgment and responsibility when operating the vehicle. Speed and driving style should always be adapted to traffic
and road conditions.

Active chassis system-Four C
Active chassis (Four C)-option
Active chassis, Four-C (Continuously Controlled Chassis Concept), regulates the characteristics of the shock absorbers
so that the car's driving characteristics can be adjusted. There are three settings: Comfort, Sport and Advanced.
Comfort
Comfort mode offers a somewhat softer ride and the transmission shifts gears at lower rpm. This mode is particularly
suitable for long-distance highway driving. The indicator light in the button will be on when this mode is selected.
Sport
In this mode, the vehicle's body sway is reduced during cornering and steering response is more immediate. The
transmission shifts up at higher rpm for sportier driving. The indicator light in the button will be on to indicate that
Sport mode has been selected.
Advanced
In this mode, body sway in curves is minimal and steering response is very direct. Gear shifting is done at high rpm in
each gear for dynamic and active driving.
Operation
Use the buttons in the center console to change setting. The setting in use when the engine is switched off is activated
the next time the engine is started.
Speed-dependent steering force (option)
Steering force increases with the speed of the vehicle to give the driver enhanced sensitivity. At low speed the vehicle
is easy to steer in order to facilitate parking, etc.
Steering force can be changed under Car settings
Steering force level. For a description of the menu system, see
page 123
.
NOTE
This menu function cannot be accessed when the vehicle is in motion.

button is released.
Press or for approximately a half second and release the button to increase or decrease vehicle speed by
approximately 1 mph (1.6 km/h).
NOTE
A temporary increase in speed by pressing the accelerator pedal, for less than 1 minute (e.g. when passing another
car), does not affect the current cruise control setting. The vehicle will automatically return to the previously set
speed when the accelerator pedal is released.
If one of the cruise control buttons is kept depressed for more than approx. 1 minute cruise control is disengaged.
The engine must then be switched off in order to reset cruise control.
Automatic deactivation
Cruise control is automatically deactivated temporarily if one of the following occurs:
If the speed drops below approximately 20 mph (30 km/h).
When the brake pedal is depressed.
If the gear selector is moved to position N.
During wheel spin or wheel lock-up.
If the vehicle's speed is increased by using the accelerator pedal for more than 1 minute.
The currently set speed will be saved in the system's memory.
