Engine Remote Start (ERS)* – introduction
ERS is a feature that makes it possible to remotely start the engine using the remotekey to cool or heat the passenger compart-ment before driving. The climate/ and infotainment systems will start using the same settings as when theengine was switched off. When the engine is started using ERS, it will run for a maximum of 15 minutes beforeautomatically switching off again. After 2 ERSstarts, the engine must be started in the nor-mal way before ERS can be used again.
NOTE
•Always adhere to applicable State, Province and/or Local laws regardingengine idling when using ERS.
• The service life of the remote key'sbattery is affected by ERS use. If thisfeature is used frequently, the batteryshould be replaced once a year, seeRemote key – replacing the battery(p. 147).
WARNING
Keep the following in mind before using ERS:
• The vehicle should be in view.
• The vehicle should be unoccupied.
• The vehicle must not be parked indoors or in an enclosed area.Exhaust fumes are harmful to thehealth.

Auto-stopping the engineNormally, when Start/Stop is activated and the brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (ECO* (p. 248)) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g., driving in heavy, stop-and-gotraffic), it may be preferableto deactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the button is pressed again or until the engine isswitched off and restarted by the driver.

ECO*
Eco is a function 10
developed by Volvo to give
the driver the opportunity to actively drive more economically and to help reduce fuelconsumption.
IntroductionWhen Eco is activated, thefollowing functions are modi-fied:
• The automatic transmission's shifting points
• The engine management system andaccelerator pedal response
• Stop/stop function (Start/Stop – introduc-tion (p. 243)): the engine can auto-stopbefore the vehicle has come to a full stop
• Eco Coast functionality is activated:engine braking 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 thefunction of certain current-consuming sys-tems will be reduced. 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 deactivated and must be reactivated eachtime the engine is started (with the exceptionof certain engines). The
ECO symbol will be displayed in the
instrument panel and the indicator light in the ECO button will be on when Eco is activated.
Eco on or offWhen ECO is deactivated, the ECO symbol will not be
displayed in the instrument panel and the indicator lightin the ECO button will be off.
The function will remaindeactivated until the buttonis pressed again.
Eco CoastEco Coast is an integral part of the Eco func- tion and essentially deactivates engine brak-ing, allowing the vehicle to roll freely.
NOTE
To function optimally, Eco Coast should primarily be used when the vehicle cancoast as far as possible.
When the driver releases the accelerator pedal, the transmission is automatically dis-engaged from the engine and engine rpm willbe reduced to the idle level(approx. 700-800 rpm), which helps reducefuel consumption.

All Wheel Drive (AWD)
Your Volvo can be equipped with permanent All Wheel Drive, which means that power isdistributed automatically between the frontand rear wheels.
Under normal driving conditions, most of the engine's power is directed to the frontwheels. However, if there is any tendency forthe front wheels to spin, an electronicallycontrolled coupling distributes power to thewheels that have the 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 alsoilluminate in the instrument panel. If thisoccurs, have the system checked by atrained and qualified Volvo service techni-cian.
Related information
• Transmission – general information (p. 238)
Brakes – general
The brake system is a hydraulic system con- sisting of two separate brake circuits. If aproblem should occur in one of these circuits,it is still possible to stop the vehicle with theother brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in 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 techni-cian and have the brake system inspected.
