ECO*
Eco is a function 10
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuel consump-tion.
IntroductionWhen Eco is activated, the fol- lowing functions are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Stop/stop function (Start/Stop – introduction(p. 262)): the engine can auto-stop beforethe vehicle has come to a full stop
• Eco Coast functionality is activated: enginebraking is disabled
• Climate system settings: certain functions(e.g., air conditioning) will be temporarilyreduced or deactivated
NOTE
When Eco is activated, several climate system parameters are changed and the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Function
ECO On/Off button in the center console
ECO symbol in the instrument panel
When the engine is switched off, ECO is deacti- vated and must be reactivated each time theengine is started (with the exception of certainengines). The
ECO symbol will be displayed in the instru-
ment panel and the indicator light in the ECO
button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, theECO symbol will not be dis-
played in the instrument panel and the indicator light in the ECO button will be off. The
function will remain deactivated until the button is pressedagain.
Eco CoastEco Coast is an integral part of the Eco function and essentially deactivates engine braking, allow-ing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should pri- marily be used when the vehicle can coast asfar as possible.
When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine and engine rpm will be reducedto the idle level (approx. 700-800 rpm), whichhelps reduce fuel consumption.

All Wheel Drive (AWD)Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distrib-uted automatically between the front and rearwheels.
Under normal driving conditions, most of the engine's power is directed to the front wheels.However, if there is any tendency for the frontwheels to spin, an electronically controlled cou-pling distributes power to the wheels that havethe best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in the AWD system. A warning light will also illu-minate in the instrument panel. If this occurs,have the system checked by a trained andqualified Volvo service technician.
Related information
• Transmission – general information (p. 256)
Brakes – general The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault has occurred. If this light comes on while driving or braking, stop immediately and check the brake fluid levelin the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the
MIN mark in the
reservoir or if a brake system message is shown in the information display: DO NOT
DRIVE . Have the vehicle towed to a trained
and qualified Volvo service technician and have the brake system inspected.

If the automatic transmission begins to over- heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy.
• It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
• When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.
CAUTION
The maximum trailer weights listed are only applicable for altitudes up to 3,280 ft(1000 m) above sea level. With increasingaltitude the engine power and therefore thecar's climbing ability are impaired because ofthe reduced air density, so the maximumtrailer weight has to be reduced accordingly.The weight of the vehicle and trailer must bereduced by 10% for every further 3,280 ft(1,000 m) (or part thereof). When towing5,000 lbs (2,250 kg) hill inclination is restric-ted to 14%.

Under normal driving conditions the transmission oil does not need changing during its service life. However, it may be necessary under adverse driving conditions.
