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 the engine is not running, depending on the ignitionmode being used.
Related information

• Ignition modes (p. 370)
• Automatic transmission (p. 395)
• Opening/closing the fuel filler door (p. 363)
• Parking brake (p. 352)
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 systemIf 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 farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function.
WARNING
If vehicle does not have electrical current and both the electric motor and gasoline engineare switched off, the brakes cannot be usedto 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 is carrying a heavy load, using brake mode B to augment the brakes or the
Off Road* drive mode can also be used to increase 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 some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when 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 the gear selector from P.
In certain cases, a message may appear in the instrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.
Light braking charges the hybrid batteryWhen 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 legal requirements 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 full pressure.
• 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 safe stop (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
•When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. Oil flow may not reachsome lubrication points fast enough toprevent engine damage.
• The engine should be idling when youmove the gear selector. Never accelerateuntil after you feel the transmissionengage. Accelerating immediately afterselecting a gear will cause harsh engage-ment and premature transmission wear.
• Selecting
P or N when idling at a stand-
still for prolonged periods of time will helpprevent overheating of the automatictransmission fluid.

Driving systems
The XC90 T8 Twin Engine Plug-in Hybrid is a parallel hybrid, which means that it has two sep-arate drive systems: an electric motor and a gas-oline engine. Depending on the drive modeselected and the amount of electric power avail-able in the hybrid battery, the two systems canbe used in tandem or separately.
Two drive systemsA control system coordinates both of the drive systems to help optimize driving economy.

ECO drive mode
The Eco drive mode is a function designed to give the driver the opportunity to drive more eco-nomically and to help reduce fuel consumption.
When this mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Climate system settings: certain functionswill be temporarily reduced or deactivated
• The suspension's self-leveling function
* low-
ers ground clearance to help reduce windresistance
• Information is shown in an ECO gauge in theinstrument panel to help promote more eco-nomical driving
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.
Selecting ECO modeWhen the engine is switched off, ECO mode is deactivated and must be reactivated each time the engine is started.
ECO will appear in the
instrument panel when the function is activated.

Shiftlock The automatic transmission's shiftlock feature helps prevent inadvertently moving the gearselector between different positions.
Automatic shiftlock
From Park – P
In order to move the gear selector from the P
position, the brake pedal must be depressed and the ignition must be in mode II.
From neutral – N
If the gear selector is in N and the vehicle has
been stationary for more than 3 seconds (regard- less of whether or not the engine is running), theshiftlock feature will lock the gear selector in thisposition. In order to move the gear selector from the N
position, the brake pedal must be depressed and the ignition must be in mode II.
Messages in the instrument panelIf the gear selector is locked in position, a mes- sage such as: Gear lever Press brake pedal
to activate gear lever will be displayed.
There is no mechanical shiftlock function.

Gear selector positions
The following gear selector positions are shown in the instrument panel:
P, R, N, D or B (brake).
For manual shifting, the gear indicator in the instrument panel shows the gear currently beingused (1–8).
Park – P
Park is activated using a switch located next to the gear selector. Select P when the vehicle is parked or when the
starting the engine. The vehicle must be station- ary when P is selected.
To select another gear, the ignition must be inmode II and the brake pedal must be depressed.
Help functions: The system will automatically shift to P:
• If the ignition is switched off while
D or R is
selected.
• If the driver unbuckles the seat belt and opens the door while the engine is running if P
has not already been selected. In position
P, the transmission is mechanically
locked. Always apply the parking brake when the vehicle is parked.
WARNING
Always apply the parking brake when the vehicle is parked, particularly when parking on a hill. The transmission's P mode may not be
able to keep the vehicle stationary if it is parked on an incline.
Reverse – R
The vehicle must be stationary before R can be
selected.
Neutral – N
No gear is selected and the engine can be started. Always apply the parking brake if thevehicle is not moving and the gear selector is in the N position.
The ignition must be in mode II and the brake
pedal must be depressed before the gear selec-tor can be moved from N.
Drive – D
D is the normal driving position and gear shifting
is fully automatic. The vehicle must be stationary when the gear selector is moved from R to D.
