Emergency braking
In an emergency, the parking brake can be activated when the vehicle is moving by pull-ing and holding up the control. The brakingprocess is canceled when the control isreleased or if the accelerator pedal isdepressed.
NOTE
In case of emergency braking at high speeds, a signal sounds during the brakeprocedure.
Deactivating the parking brake
Deactivating manually
1. Depress the brake pedal firmly.2. Press the control.
> The parking brake will release and thesymbol in the instrument panel will go out.
Deactivating automatically
1. Start the vehicle.
2. Depress the brake pedal firmly. Move the gear selector to D or R and press the
accelerator pedal.

Braking assist after a collision
In a collision in which the activation level is reached for the pyrotechnic seat belt tension-ers or airbags, or if a collision with a large ani-mal is detected, the vehicle's brakes will beautomatically activated. This function isintended to help prevent or reduce the effectsof any subsequent collision.
After a serious collision, it may no longer be possible to control and steer the vehicle. Inorder to avoid or mitigate a possible furthercollision with a vehicle or an object in the vehi-cle's path, the brake assist system is activatedautomatically to help stop the vehicle safely. If braking is not appropriate, e.g. if there is a risk of being hit by passing traffic, the drivercan override the system by depressing theaccelerator pedal. This function assumes that the brake system is intact after a collision.

Transmission
The transmission is part of the vehicle's drive- line (power transmission) between the engineand the drive wheels. The function of thetransmission is to change gears dependingon speed and power needs.
The vehicle has an 8-speed automatic trans- mission and an electric motor for rear-wheeldrive. The number of gears allows the engine'storque and power band to be effectively uti-lized. Two of the gears are overdrive gears thatsave fuel when driving at a constant enginespeed. Manual shifting is also possible. Theinstrument panel shows the gear currently inuse.

Automatic transmission
In vehicles with an automatic transmission, the system selects the gear so that drivingwill be as energy-efficient as possible. Thetransmission also has a manual mode.
Overview of gear selector and gear shift pattern in the instrument panel
The instrument panel shows which gear is cur- rently in use: R , N , D or B. P position is electric.
For manual shifting, the gear indicator in the instrument panel displays the gear currentlybeing used.

Gear selector positions for automatic transmissions
With an automatic transmission, a suitable gear is selected automatically according tocurrent speed and power requirements.
Selecting gearsThe gear selector is a shift-by-wire selector, where shifting is done electronically instead ofmechanically. This makes shifting easier andthe gear positions more distinct.
Gear selector and gear selector positions overview.
Change gear position by pushing the spring- loaded gear selector forward or rearward, or tothe side for manual shifting.

Brake - B
Brake position in instrument panel overview.
From the B position, it is possible to shift
manually. B can be selected at any time while
driving. When the accelerator pedal is released, the electric motor brakes the vehicleand the hybrid battery is recharged at thesame time. This offers additional opportunitiesto recharge the hybrid battery, since the bat-tery is charged even when the brake pedal isnot depressed. Select brake by moving the gear selector rear- ward from the D position. The currently
selected gear will be displayed in the instru-ment panel.
Push the gear selector to the right toward"
+ " (plus) and release to shift up one gear.
Push the gear selector to the left toward"
– " (minus) and release to shift down one
gear.
Push the gear selector rearward to returnto
D mode.
For smooth shifting and engine performance,the transmission will shift down automaticallyif the vehicle's speed becomes too low for theselected gear.

To move the gear selector from P to another
gear, the brake pedal must be depressed and the ignition in mode II.

If the gear selector is in N and the vehicle has
been stationary for at least 3 seconds (with or without the engine running), the gear selectorwill be locked in that position. To move the gear selector from N to another
gear, the brake pedal must be depressed and the ignition in mode II.

WARNING
Do not leave the vehicle in an unventilated area with a drive mode activated and thecombustion engine switched off. Theengine will start automatically if the chargelevel in the hybrid battery is low and theresulting exhaust gases can be very harm-ful to people and animals.
Hybrid
This is the default mode in which the elec- tric motor and combustion engine worktogether.
The vehicle starts in
Hybrid mode. The control
system uses both the electric motor and the gasoline engine – separately or in tandem –and adapts utilization with regard to perform-ance, fuel consumption and comfort. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat or cooling inthe passenger compartment, etc. If there is sufficient charge in the battery, it is possible to drive solely on electric power.When the accelerator pedal is pressed, onlythe electric motor will be activated until thebattery reaches a certain charge level. Abovethis level, the current in the battery cannotsupply the power requested by the acceleratorpedal and the combustion engine will start. When the hybrid battery's charge level is low, the combustion engine will start more fre- quently to save the remaining current in thebattery. Charge the hybrid battery from a120-240 volt outlet using a charging cable, or activate
Charge in Function view to reset the
option of only using the electric motor. This drive mode is designed for low energy consumption with a mix between the electricmotor and gasoline engine, without compro-mising on climate comfort or driving experi-ence. When faster acceleration is requestedby the driver, the electric driveline will be uti-lized to help provide maximum additionalpower. The vehicle also monitors the driving condi- tions and automatically engages all-wheeldrive if necessary. All-wheel drive and extraelectric power are always available regardlessof the battery's charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will be displayed in the instrument panel. Thegauge will indicate the amount of electricalcurrent required when the driver depressesthe accelerator pedal. The marker between thelightning and the drop shows how much cur-rent is available.
The instrument panel gauge when both the electric motor and the combustion engine are being used.
The instrument panel also shows how much current is being restoredto the battery (regenerated) duringlight braking.

Using the electric or combustion engine
An advanced control system determines the distance that the vehicle can be driven on thecombustion engine, electric motor, or both atthe same time. Its primary function is to use the motor/engine and the current available in the hybrid batteryas efficiently as possible based on the charac-teristics of the various drive modes and thepower output requested by the driver bypressing the accelerator pedal. In certain cases, temporary limitations in the system or mandatory functions to help main- tain a low overall emissions level may result in greater use of the combustion engine.

Leveling control * and suspension
Self-leveling and suspension functions are controlled automatically.
Rear leveling control keeps the rear section of the vehicle at the same height regardless ofload. Leveling control may also remain activewhen the vehicle is parked.
Shock absorbers (Four-C)On vehicles equipped with Four-C, the shockabsorbers are adapted to the selected drive mode and the current vehicle speed. Theshock absorbers are normally set to help opti-mize comfort and are adjusted continuouslyaccording to the road surface and the vehicle'sacceleration, braking and cornering.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspension
may occur during transport, which couldadversely affect the lashing and result in dam-age.
