Available drive modes
HYBRID
This is the default mode. The vehicle normally starts in
Hybrid mode 4
. The
engine management system uses both the elec- tric motor and gasoline engine (separately or intandem) and calculates the optimal levels of per-formance, fuel consumption and comfort. Athigher speeds, ground clearance is reducedautomatically to help reduce wind resistance. The amount of driving done using only the elec- tric motor in
Hybrid mode is determined by the
hybrid battery's charge level and the need for heating/cooling in the passenger compartment. If sufficient electrical energy is available, only the electric motor will be activated when the driverpresses the accelerator pedal up to a certainlevel. Above this level, the gasoline engine willstart.The instrument panel gauge when both the electric motor and gasoline engine are being used
The long needle in the gauge indicates the amount of energy that the vehicle is currentlyusing. The short white line between the "light-ning" and "oil drop" symbols indicates theamount of energy available. See also the article"General information about the XC90 T8 TwinEngine Plug-in Hybrid" for additional information. The gasoline engine starts when the response required when the driver presses the acceleratorpedal cannot be provided by the electric motoralone. The gauge also indicates when the battery is being recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation. When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible or switch to the
Save drive mode.
PURE
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions. Ground clearance will be lowered to help reduce wind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery is
sufficiently charged. If the level gets too low, the gasoline engine will start. The gasoline engine will also start: • If the vehicle's speed goes above approx. 75 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that have been reduced in the mode, press the,
AUTO or
defroster buttons.

SAVE
This mode makes it possible to save electrical energy (hybrid battery charge) for times whenusing the electric motor is more suitable (e.g., citydriving). Using the electric motor only saves more fuel at low speeds than at high ones. Therefore, use theSAVE mode primarily when the hybrid battery'scharge level is high and driving will initially be athighway speeds but will end with city drivingwhen electric driving is preferable. If the hybrid battery's charge level is low when this mode is selected, the gasoline engine willstart and charge the hybrid battery up to approx.33%. If the battery's charge level is already above33%, this level will be maintained by the enginemanagement system, which will start/stop the gasoline engine in the same way as in
Hybriddrive mode. This mode increases fuel consumption because the gasoline engine is used to conserve batterycharge for later use.
OFF ROAD
This mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, All Wheel Drive and HillDescent Control are activated and a compassand altimeter will be displayed in the instrumentpanel.This drive mode can only be activated at lowspeeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated. This mode is not intended for normal street driv- ing.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
Due to the increased ground clearance, if the OFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.
AWD
This mode offers improved traction using four- wheel drive and is intended primarily for low-speed driving on slippery surfaces. However, italso helps increase directional stability at higherspeeds. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.
POWER
Power mode is intended for sportier, more active
driving. This mode maximizes the combined effects of the electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherspeeds. Steering response is also more immedi-ate, the suspension is stiffer and lower groundclearance reduces body roll when cornering. In this mode, both the electric motor and the gas- oline engine are used continuously, which resultsin higher fuel consumption.

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.

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.

Brake – B
B can be selected at any time during a drive. In
this 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 gears
is possible. The gear indicator in the instrument panel 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, the vehicle must be equipped with steering wheel paddles *.
• Press the gear selector forward to return to D
mode. For smooth shifting and engine performance, the transmission will shift down automatically if thevehicle's speed becomes too low for the selectedgear.
Safety functionTo 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 shift down one or more gears, depending on theengine's rpm and will shift up again when max.rpm is reached for a specific gear.

Low Speed Control (LSC) Low Speed Control (LSC) helps make off-road driving easier on slippery surfaces when towinga trailer on grass, etc. This feature is part of the
Off Road drive mode.
When driving at low speeds, LSC prioritizes low gears and all wheel drive to help avoid wheel spinand to improve the vehicle's tractive force. Theaccelerator pedal and engine react differently tomake low-speed driving easier. It is activated along with Hill Descent Control (HDC), which increases engine braking to helpkeep vehicle speed low and smooth, even drivingdown steep hills.

function. Select any other drive mode to turn it off.
NOTE
When LSC with HDC is activated by the Off
Road drive mode, the feel of the accelerator
pedal and engine response will change. The function is deactivated when driving at higher speeds and must be reactivated atlower speeds if so desired.

All Wheel Drive (AWD) 8
Your Volvo can be equipped with All Wheel Drive, which means that power is distributedautomatically between the front and rear wheels.
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. AWD reacts differently, depending on the drive mode * selected.

Suspension and leveling control
*
The leveling control system adjusts the suspen- sion and shock absorbers automatically to helpprovide good comfort and control while driving.Leveling can also be controlled manually tomake loading or getting in and out of the vehicleeasier.
Pneumatic suspension and shock absorbers
This system is linked to the selected drive mode and is adapted to the vehicle's speed. The pneu-matic suspension reduces the vehicle's groundclearance at higher speeds to reduce wind resis-tance and increase stability. The shock absorbersare normally set to provide the best possiblecomfort and are adjusted continuously accordingto the road surface, acceleration, braking andcornering. A message will be displayed in the instrument panel when the suspension level is beingadjusted. The level cannot be adjusted if one of the side doors or the hood is open.

Loading mode
Use the buttons in the cargo compartment to raise or lower the vehicle to make loading orunloading easier or when attaching a trailer.
Parking the vehicleWhen parking, be sure that there is adequatespace above and below the vehicle since itsground clearance may vary, e.g., depending onthe ambient temperature, how the vehicle is loa-ded, if loading mode is being used or the drivemode selected after the engine is started. The level may also be adjusted for a certain time after the vehicle has been parked to compensatefor possible height adjustments due to tempera-ture changes in the pneumatic suspension whenthe vehicle has cooled.
TransportWhen transporting the vehicle on a ferry, train ora tow truck, it may only be secured (lashed)around the tires, not using any other chassiscomponents. Changes in the pneumatic suspen-sion may occur during transport that could nega-tively affect the lashing and result in damage.
