STARTING AND DRIVING

Starting and driving
The vehicle is equipped with an automatic trans-mission that also makes it possible to shift gearsmanually.
Certain functions can also be used when theengine is not running, depending on the ignitionmode being used.

•Parking brake (p. 382)
Brakes
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.
Brake system
If one of the brake circuits is not functioning,more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect.
If the brake pedal must be depressed fartherthan normal and requires greater foot pressure,the stopping distance will be longer.
Pressure on the brake pedal is enhanced by thepower braking function.

WARNING
If the vehicle does not have electrical currentand both the electric motor and gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
When the Hill Start Assist function is being used,it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface.
When driving in very hilly areas or if the vehicle iscarrying a heavy load, using brake mode B toaugment the brakes or the Off Road* drive
mode can also be used on steep downgrades toincrease the engine braking effect at low speeds.
Anti-lock Braking System ABS
The ABS system helps to improve vehicle control(stopping and steering) during severe brakingconditions by limiting brake lockup.
When ABS is operating, there may be somevibration in the brake pedal, which is normal.
The system performs a brief self-diagnostic testwhen the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.

Function check when the engine is
started
A Plug-in Hybrid is equipped with a "brake bywire" brake system. A function check is per-formed each time the engine is started and thedriver depresses the brake pedal to move thegear selector from P.
In certain cases, a message may appear in theinstrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.

Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor's braking function is used, which converts

Driving with a trailer
When towing a trailer, always observe the legalrequirements of the state/province.
•All Volvo models are equipped with energy-absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
•Increase tire pressure to recommended fullpressure.
•When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
•Maximum speed when towing a trailer:50 mph (80 km/h).
•Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
•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 ona hill, apply the parking brake before put-ting the gear selector in P. Always followthe trailer manufacturer's recommenda-tions for wheel chocking.
•When starting on a hill, put the gearselector in D before releasing the parkingbrake.
•If you use the manual (Geartronic) shiftpositions 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%.

STARTING AND DRIVING

Automatic transmission
The automatic transmission has 8 forward gearsand an electric motor that powers the rearwheels. Steering wheel paddles* make it possi-ble to shift manually. The gear indicator in theinstrument panel shows the gear currently beingused or gear shift mode.

Gear shift indicator
The gear shift indicator in the instrument panelshows the current gear (in manual shiftingmode) and will prompt the driver to shift up ordown to help get the best possible fuel econ-omy.
The gear shift indicator shows the current gear inthe instrument panel and uses an upward arrowto recommend shifting to a higher gear. The indi-cator is also shown in mode B or if the steeringwheel paddles* are being used in while the trans-mission is in mode D.

Gear selector positions
The shift-by-wire gear transmission shifts gearselectronically instead of mechanically for fasterand more distinct gear shifting.
Selecting gears
Select gears by moving the spring-loaded, non-locking gear selector forward or rearward.
Gear selector positions
The following gear selector positions are shownin the instrument panel:
P, R, N, D or B (brake).
For manual shifting, the gear indicator in theinstrument panel shows the gear currently beingused (1–8).

Brake – B
B can be selected at any time during a drive. Inthis mode, the engine braking function is acti-vated when the accelerator pedal is released,which helps charge the hybrid battery. Thismeans that the hybrid battery is charged even ifthe brake pedal is not depressed.
B mode in the instrument panel
With B selected, manual shifting to lower gearsis possible. The gear indicator in the instrumentpanel shows the gear currently being used (1–8).
Each time the gear selector is pulled rearward,the transmission will shift down one gear.
In order to manually shift to higher gears, thevehicle must be equipped with steering wheelpaddles*.
•Press the gear selector forward to return toD mode.
For smooth shifting and engine performance, thetransmission will shift down automatically if thevehicle's speed becomes too low for the selectedgear.

Safety function
To help avoid excessive rpm that might causeengine damage, the transmission control modulehas a down-shift protection feature that in somesituations may prevent a down-shift or kickdown.
During kickdown, the transmission may shiftdown one or more gears, depending on theengine's rpm and will shift up again when max.rpm is reached for a specific gear.

Steering wheel paddles*
In addition to the manual gearshift function usingthe gear selector, the paddles make it possibleto manually shift gears from the steering wheel.
Activating the paddles
In order to shift gears with the paddles, they haveto first be activated. To do so:
–Pull either paddle toward the steering wheeland release it.
>A number in the instrument panel will indi-cate the current gear being used.

Shifting
To shift one gear:
