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. The number of gears allows theengine's torque and power band to be effec-tively utilized. Two of the gears are overdrivegears that save fuel when driving at a constantengine speed. Manual shifting is also possible.The instrument panel shows the gear currentlyin use.

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.
The transmission is available in different ver- sions. The gear selector indicates which trans-mission the vehicle has. The various gearselectors have different functions.

Overview of small gear selector and gear shift pat- tern in the instrument panel
The instrument panel shows which gear is cur- rently in use: P , R , N , D or M. For vehicles with the small
gear selector, P position is electric and the
gear shift pattern is instead R, N , D or M.
For manual shifting, the gear indicator in the instrument panel displays the gear currentlybeing used.
CAUTION
Check the operating temperature of the transmission to help avoid damage to anyof the drive system components. If there isa risk of overheating, a warning symbol willappear in the instrument panel and a textmessage will be displayed. Follow the rec-ommendations given.
Symbols in the instrument panelIf a problem should occur with the transmis- sion, a symbol and a message will appear inthe instrument panel.

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.

For the small gear selector, change gear posi- tion by pushing the spring-loaded gear selec-tor forward or rearward, or to the side formanual shifting.
Gear selector positions
Park - P
For the small gear selector, Park is activated using the P button next to the gear selector.
For the large gear selector, Park is activatedby moving the gear selector to position P.
In P mode, the transmission is mechanically
locked. Select P when the vehicle is parked or when
starting the engine. The vehicle must be sta- tionary when Park is selected. To move to another gear from Park, the brakepedal must be depressed and the ignition inmode
II. For vehicles with the small gear
selector, the engine must be running. When parking – apply the parking brake before shifting to Park.
WARNING
Always apply the parking brake when park- ing on an incline. Selecting a gear or put-ting the automatic transmission in P may
not be sufficient to keep the vehicle sta-tionary in all situations.
NOTE
The gear selector must be in position P in
order to lock the vehicle and set the alarm.

For vehicles with the small gear selector, the system will shift to P automatically
if the ignition is switched off while
D or R
is selected.

P.
To park a vehicle with an unbuckled seat beltand open door – end P mode by shifting to R
or D again.
The system will not automatically shift to P if
the ignition is switched off while the gearselector is in the neutral position (N). This is tomake it possible to wash the vehicle in anautomatic car wash in which the vehicle ispulled forward on rolling wheels.
Reverse - R
Select R when backing up. The vehicle must
be stationary when Reverse is selected.
Neutral - N
No gear is selected and the engine can be started. Apply the parking brake if the vehicleis stationary with the gear selector in N.
To move the gear selector from N to another
gear, the brake pedal must be depressed andthe ignition in mode II. For vehicles with the small gear selector, the engine must be run-ning.
D
drive mode
D is the normal driving gear position. The
transmission shifts up or down automatically depending on acceleration and speed. The vehicle must be stationary when the gear selector is moved from R to D.
Manual shifting mode - M
Overview of gear shift pattern in the instrument panel for large gear selector.
Manual shifting mode can be selected at any time during a drive. Engine braking will occurwhen the accelerator pedal is released. Select manual shifting mode by moving the gear selector sideways from D to ±. The cur- rent gear will be displayed in the instrumentpanel.
