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 Adaptive Cruise 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 is 200 km/h (125 mph).

Setting Adaptive Cruise Controltime intervals Adaptive Cruise Control (ACC 47
) can be set to
various time intervals to the vehicle ahead.
Different time intervals to the vehicle 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 of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds. The same symbol appears when the Distance Alert function is activated.
NOTE
When the symbol in the instrument panel shows two vehicles, ACC is following the vehi-cle ahead at a preset time interval. When only one vehicle is shown, there is no vehicle ahead within a reasonable distance.
Controls for setting a time interval 48
.
Reduce the time interval
Increase the time interval
Distance indicator
–Press the (1) or (2) button to decrease or increase the time interval.
> The distance indicator (3) shows the cur-
rent time interval.
In order to help your vehicle follow the vehicle ahead 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.

–Change a set speed by pressing the (1)
or
(2) buttons briefly or by pressing and
holding them:
• Press briefly
: Press briefly: each press
changes the speed in +/- 5 mph (+/- 5 km/h) increments.
• Press
and hold: Release the button when
the set speed indicator (3) has moved tothe desired speed.
• The most recently set speed will be stored.
If speed is increased by depressing the accelera- tor pedal while pressing the
button on the
steering wheel, the vehicle's speed when the but- ton is pressed will be stored as the set speed. Temporarily increasing speed using the accelera- tor pedal, e.g. when passing another vehicle, willnot affect the setting. The vehicle will return tothe set speed when the accelerator pedal isreleased.
Automatic transmission
Pilot Assist can follow another vehicle at speeds from a standstill up to 200 km/h (125 mph). The lowest speed that can be set for Pilot Assist is 30 km/h (20 mph). When following anothervehicle, ACC can monitor that vehicle's speedand slow your own vehicle down to a standstill,but it is not possible to set speeds lower than30 km/h (20 mph). The highest possible speed that can be set is200 km/h (125 mph).

Setting a time interval for PilotAssist
Pilot Assist can be set to different time intervals.
Different time intervals to the vehicle 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 of
approx. 1 second to the vehicle ahead. 5 barsrepresents approx. 3 seconds.
NOTE
When the symbol in the instrument panel shows a vehicle and a steering wheel, PilotAssist follows a vehicle ahead at a presettime interval. When only a steering wheel is shown, there is no vehicle ahead within a reasonable dis-tance.

STARTING AND DRIVING
426
NOTE
With a cold start, idling speed may be consid- erably higher than normal for certain enginetypes. This is done to get the emissions sys-tem up to normal operating temperature asquickly as possible, which minimizes exhaustemissions and protects the environment.
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 from overheating, select
P or N when idling at
a standstill for prolonged periods of time.

Parking on a hill
Always use the parking brake when parking on a hill.
WARNING
Always apply the parking brake when parking on an incline. Selecting a gear or putting the automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit- uations.
If the vehicle is pointing uphill: • Turn the front wheels so they are pointing away from
the curb.
If the vehicle is pointing downhill:
• Turn the front wheels so they are pointingtoward
the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the vehicle to roll backward when the parking brakeis released automatically on steep uphill gradi-ents. To help avoid this, pull the control upwardwhile you are driving away. Release the controlwhen the vehicle gains traction.

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 steering wheel paddles
* can be used to shift up or down
manually. The instrument panel shows the gear currently in use.
CAUTION
Check the operating temperature of the transmission 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 panelIf a problem should occur with the transmission, a symbol and a message will appear in the instru-ment panel.

ation performance reduced
In the event of a temporary fault in the driveline, the vehicle may gointo a "limp home" mode withreduced power output to help avoiddamage to the driveline.

Gear selector positions forautomatic transmissions In vehicles with an automatic transmission, the system 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 the instrument panel displays the gear currentlybeing used (1-8).
Selecting gearsThe gear selector is a shift-by-wire selector,where shifting is done electronically instead ofmechanically. This makes shifting easier and thegear positions more distinct. 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 next
to the gear selector. Select
P when the vehicle is parked or when star-
ting the engine. The vehicle must be stationary when Park is selected. To move to another gear from Park, the brake pedal must be depressed and the ignition in mode II.
When parking – apply the parking brake before shifting to Park.
WARNING
Always apply the parking brake when parking on an incline. Selecting a gear or putting the automatic 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 position
before the vehicle can be locked and the alarm set.
