Transmission – Geartronic
Geartronic allows you to manually shift among your vehicle's forward gears. The manualposition ( +S–) can be selected at any time.
Geartronic: manual shifting (+S–)To shift gears manually, move thegear selector to the side from D
toward +S–. The +S– symbol in the
instrument panel will change from
white to orange and the number of the gear
currently being used (
1, 2, 3, etc.) will be dis-
played (see the following illustration) 5
.
• To return to automatic shifting mode from +S–
, move the gear selector to the side
toward D.
Gear shift indicator*
Gear shift indicator in a digital instrument panel* 6This option indicates when to shift up or down to help conserve fuel. A white arrow willappear above or below the number of thecurrent gear to prompt the driver to shift upor down.
While driving
•
If you select the manual shifting position while driving, the gear that was beingused in the Drive position will also initiallybe selected in the manual shifting posi-tion.
• 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 gearat a time and will utilize the braking powerof the engine. If the current speed is toohigh for using a lower gear, the downshiftwill not occur until the speed hasdecreased enough to allow the lower gearto be used.
• If you slow to a very low speed, the trans-mission will automatically shift down.
Shiftlock: Neutral (N)If the gear selector is in the
N position and
the vehicle has been stationary for at least 3 seconds (irrespective of whether the engineis running) then the gear selector is locked. In order to move the gear selector from
N to
another gear position, the brake pedal mustbe depressed and the ignition must be in atleast position II, see Ignition modes (p. 73).

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.

This feature is primarily intended to be used in driving situations where a decrease inspeed is expected, such as when approach-ing an intersection or a traffic light.
Eco Coast enables proactive driving with as little braking as possible.
Combinations of On and OffDepending on the driving situation, Eco can be used in different ways to help reduce fuelconsumption:
• With Eco activated
: this enables Eco
Coast, which allows the vehicle to roll
freely for as far as possible when the
driver releases the accelerator pedal (e.g., when approaching a traffic light or inter-section).
or
• With Eco deactivated
: engine braking
can be used when the vehicle will only
roll for a short distance (in heavy traffic,
etc.) or when driving down hills .
To help keep fuel consumption as low as possible, Eco Coast should not be used intraffic situations where the brakes have to beused frequently.
Activating Eco CoastEco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D •
The vehicle's speed is between approxi- mately 40–85 mph (65–140 km/h). Alwaysobserve posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
Deactivating Eco CoastIn certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to utilize engine braking
• Prior to passing another vehicle, in orderto do so as safely as possible
Deactivating Eco Coast (and reactivating engine braking) can be done in the followingways:
• Press the
ECO button on the center con-
sole
• Move the gear selector to the manual "
S
+/– " position
• Change gears using the steering wheel paddles*
• Press the brake or accelerator pedal
Eco Coast limitationsThis function will not be available if:
• Cruise control is activated
• The gradient of a down-slope is morethan approximately 6%
• The steering wheel paddles* are used tomanually change gears •
The engine and/or transmission have notreached their normal operating tempera-ture
• The gear selector is moved from
D to the
manual " S+/–" position
• The vehicle's speed is not within the40–85 mph (65–140 km/h). interval
Additional information and settings
Other ECO-related settings can be made in the vehicle's
MY CAR menu. See My Car –
introduction (p. 70) for more information.

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.
