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 that
vehicle's speed and slow your own vehicle down
to a standstill, but it is not possible to set speeds
lower than 30 km/h (20 mph).
The highest possible speed that can be set is
200 km/h (125 mph).

Adaptive Cruise Control* (p. 300) Setting Adaptive Cruise Control
time intervals
Adaptive Cruise Control (ACC
44
) can be set to
various time intervals to the vehicle ahead.
Different time intervals to the
vehicle ahead can be selected
and are shown in the instru-
ment panel as 1–5 horizontal
bars. The more bars, the longer
the time interval. One bar rep-
resents an interval of
approx. 1 second to the vehicle ahead. 5 bars
represents 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

– 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 interval
to vary noticeably in certain situations. At low
speeds, when the distance to the vehicle ahead
is short, Adaptive Cruise Control increases the
time interval slightly. 44

Pilot Assist can be set to various speeds.
Setting/changing set speed
Note: This illustration is general and details may vary
depending on model and market.
: Increases the set speed
: Reduces the set speed
Set speed –
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 to
the desired speed.
The most recently set speed will be stored.
If speed is increased by depressing the accelera-
tor pedal while pressing the (1) button on
the steering wheel, the vehicle's speed when the
button is pressed will be stored as the set speed.
Temporarily increasing speed using the accelera-
tor pedal, e.g. when passing another vehicle, will
not affect the setting. The vehicle will return to
the set speed when the accelerator pedal is
released.
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 another
vehicle, ACC can monitor that vehicle's speed
and slow your own vehicle down to a standstill,
but it is not possible to set speeds lower than
30 km/h (20 mph). The highest possible speed that can be set is
200 km/h (125 mph).

CAUTION

When starting in cold weather, the auto-
matic transmission may shift up at slightly
higher engine speeds than normal until
the automatic transmission fluid reaches
normal operating temperature.
Do not race a cold engine immediately
after starting. This could prevent fluids
from properly lubricating vital compo-
nents in the engine before it has reached
the proper operating temperature.
The engine should be idling when the
gear selector is moved. Never accelerate
until the gear is fully engaged. Accelerat-
ing rapidly before a gear is properly
engaged could lead to harder wear of
components.
To help prevent the transmission oil from
overheating, select P or N when idling at
a standstill for prolonged periods of time.

The vehicle's brakes are used to reduce speed
or prevent the vehicle from rolling.
In addition to the wheel brakes and parking
brakes, the vehicle is also equipped with a num-
ber of automatic brake assist functions. These
systems help the driver by e.g. keeping the vehi-
cle stationary when the brake pedal is not
depressed (e.g. at a traffic light or intersection),
when starting up a hill or when driving down a hill.
Depending on how the vehicle is equipped, the
following brake assist functions may be included:
Auto-hold brakes (Auto Hold)
Hill Start Assist (Hill Start Assist)
Braking assist after a collision

Parking brake (p. 442) 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 pointing
toward the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the
vehicle to roll backward when the parking brake
is released automatically on steep uphill gradi-
ents. To help avoid this, pull the control upward
while you are driving away. Release the control
when the vehicle gains traction.

Brake functions (p. 438) Transmission
The transmission is part of the vehicle's driveline
(power transmission) between the engine and
the drive wheels. The function of the transmis-
sion is to change gears depending on speed
and 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 torque
and power band to be effectively utilized. Two of
the gears are overdrive gears that save fuel when
driving 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 of
the drive system components. If there is a risk
of overheating, a warning symbol will appear
in the instrument panel and a text message
will be displayed. Follow the recommenda-
tions given.
Symbols in the instrument panelIf a problem should occur with the transmission, a

Reduced performance/Acceler-
ation performance reduced
In the event of a temporary fault in
the driveline, the vehicle may go
into a "limp home" mode with
reduced power output to help avoid
damage to the driveline.

Gear selector positions for
automatic transmissions
In vehicles with an automatic transmission, the
system selects the optimal gear for the current
driving conditions. The transmission also has a
manual 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 currently
being used (1-8).
Selecting gearsThe gear selector is a shift-by-wire selector,
where shifting is done electronically instead of
mechanically. This makes shifting easier and the
gear 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.
