Automatic transmission
Adaptive Cruise Control can follow another vehi-cle at speeds from a standstill up to 200 km/h(125 mph).
The lowest speed that can be set for AdaptiveCruise Control is 30 km/h (20 mph). When fol-lowing another vehicle, ACC can monitor thatvehicle's speed and slow your own vehicle downto a standstill, but it is not possible to set speedslower than 30 km/h (20 mph).
The highest possible speed that can be set is200 km/h (125 mph).

Setting Adaptive Cruise Controltime intervals
Adaptive Cruise Control (ACC39) can be set tovarious time intervals to the vehicle ahead.
Different time intervals to thevehicle ahead can be selectedand are shown in the instru-ment panel as 1–5 horizontalbars. The more bars, the longerthe time interval. One bar rep-resents an interval ofapprox. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
The same symbol appears when the DistanceAlert function is activated.

NOTE
When the symbol in the instrument panelshows two vehicles, ACC is following the vehi-cle ahead at a preset time interval.
When only one vehicle is shown, there is novehicle ahead within a reasonable distance.
Controls for setting a time interval40.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease orincrease the time interval.
> The distance indicator (3) shows the cur-rent time interval.
In order to help your vehicle follow the vehicleahead as smoothly and comfortably as possible,Adaptive Cruise Control allows the time intervalto vary noticeably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Adaptive Cruise Control increases thetime interval slightly.

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. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it has reachedthe proper operating temperature.
The engine should be idling when thegear selector is moved. Never accelerateuntil the gear is fully engaged. Accelerat-ing rapidly before a gear is properlyengaged could lead to harder wear ofcomponents.
To help prevent the transmission oil fromoverheating, select P or N when idling ata standstill for prolonged periods of time.

Transmission
The transmission is part of the vehicle's driveline(power transmission) between the engine andthe drive wheels. The function of the transmis-sion is to change gears depending on speedand power needs.
The vehicle has an 8-speed automatic transmis-sion and an electric motor for rear-wheel drive.The number of gears allows the engine's torqueand power band to be effectively utilized. Two ofthe gears are overdrive gears that save fuel whendriving at a constant engine speed. The steeringwheel paddles* can be used to shift up or downmanually. The instrument panel shows the gearcurrently in use.

CAUTION
Check the operating temperature of thetransmission to help avoid damage to any ofthe drive system components. If there is a riskof overheating, a warning symbol will appearin the instrument panel and a text messagewill be displayed. Follow the recommenda-tions given.

Symbols in the instrument panel
If a problem should occur with the transmission, asymbol and a message will appear in the instru-ment panel.
Symbol Meaning
Information and messages relatedto the transmission. Follow the rec-ommendations provided.
Hot or overheated transmission.Follow the recommendations provi-ded.
Reduced performance/Acceler-ation performance reduced
In the event of a temporary fault inthe driveline, the vehicle may gointo a "limp home" mode withreduced power output to help avoiddamage to the driveline.

Gear selector positions for automatic trans-missions (p. 440)
Gear selector positions forautomatic transmissions
In vehicles with an automatic transmission, thesystem selects the optimal gear for the currentdriving conditions. The transmission also has amanual mode.
The instrument panel shows which gear is cur-rently in use:
P, R, N, D or B.
For manual shifting, the gear indicator in theinstrument panel displays the gear currentlybeing used (1-8).

Selecting gears
The gear selector is a shift-by-wire selector,where shifting is done electronically instead ofmechanically. This makes shifting easier and thegear positions more distinct.

STARTING AND DRIVING
}}
441
Select gears by moving the spring-loaded, non-locking gear selector forward or backward.

Gear selector positions
Park - P
Park is activated using the P button located nextto the gear selector.
Select P when the vehicle is parked or when star-ting the engine. The vehicle must be stationarywhen Park is selected.
To move to another gear from Park, the brakepedal must be depressed and the ignition inmode II.
When parking – apply the parking brake beforeshifting to Park.
WARNING
Always apply the parking brake when parkingon an incline. Selecting a gear or putting theautomatic transmission in P may not be suffi-cient to keep the vehicle stationary in all sit-uations.

NOTE
The gear selector must be in the P positionbefore the vehicle can be locked and thealarm set.
Help functions
The system will automatically shift to P:
if the ignition is switched off while D or R isselected.
if the driver unbuckles the seat belt andopens the driver's door while the vehicle isrunning with the gear selector in a gear otherthan P.
To park a vehicle with an unbuckled seat belt andopen door – end P mode by shifting to R or Dagain.
The system will not automatically shift to P if theignition is switched off while the gear selector isin the neutral position (N). This is to make it pos-sible to wash the vehicle in an automatic carwash in which the vehicle is pulled forward onrolling wheels.
Reverse - R
Select R when backing up. The vehicle must bestationary when Reverse is selected.

Neutral - N
No gear is selected and the engine can bestarted. Apply the parking brake if the vehicle isstationary with the gear selector in N.
To move the gear selector from Neutral toanother gear, the brake pedal must be depressedand the ignition in mode II.

D drive mode
D is the normal driving gear position. The trans-mission shifts up or down automatically depend-ing on acceleration and speed. The vehicle mustbe stationary when the gear selector is movedfrom R to D.
