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

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.

||STARTING AND DRIVING
* Option/accessory.
440 Help functions
The system will automatically shift to P:
• if the ignition is switched off while D or R is
selected.
• if the driver unbuckles the seat belt and
opens the driver's door while the vehicle is
running with the gear selector in a gear other
than P.
To park a vehicle with an unbuckled seat belt and
open door – end P mode by shifting to R or D
again.
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 vehicle is
stationary with the gear selector in N.
To move the gear selector from Neutral to
another gear, the brake pedal must be depressed
and 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 must
be stationary when the gear selector is moved
from R to D.
Brake - B
B can be selected at any time during a drive. In B
mode, the engine braking function is activated
when the accelerator pedal is released, which
helps charge the hybrid battery. This offers addi-
tional opportunities to recharge the hybrid bat-
tery, since the battery is charged even when the
brake pedal is not depressed. B mode in the instrument panel.
From B mode, it is possible to manually shift to
lower gears. The currently selected gear (1-8) will
be displayed in the instrument panel.
• Pull the gear selector backward once to shift
down one gear.
• Pull the gear selector backward again to shift
down to lower gears.
To shift manually to a higher gear, the vehicle
must be equipped with steering wheel paddles*. •
Push the gear selector forward to return to D
mode.
For smooth shifting and engine performance, the
transmission will shift down automatically if the
vehicle's speed becomes too low for the selected
gear.

Using the steering wheel paddles*
to shift
The steering wheel paddles are a supplement to
the gear selector and make it possible to shift
manually without removing your hands from the
steering wheel.
Activating the steering wheel paddlesIn order to shift gears using the paddles, they
must first be activated:
– Pull one of the paddles toward the steering
wheel.
>

A number in the instrument panel indi-
cates the current gear being used. Instrument panel when the paddles are activated for
shifting.
ChangeTo shift one gear: –
Pull one of the paddles toward the steering
wheel and then release. "-": Shift down one gear.
"+": Shift up one gear.
As long as the engine speed (rpm) is within the
permissible range for the selected gear, a gear
shift will take place each time a paddle is pulled.
After each gear shift, a number indicating the
current gear will be displayed in the instrument
panel.
Turning off Start/Stop
Manual deactivation in gear D and B
– Deactivate the paddles by pulling the right
paddle (+) toward the steering wheel and
holding it until the number of the current
gear is no longer displayed in the instrument
panel.
> The transmission will revert to gear D or B
depending on which gear was selected
before the paddles were activated.
Automatic deactivation
In gear position D, the steering wheel paddles
are deactivated after a short period of time if they
are not used. The number of the current gear will
no longer be displayed in the instrument panel.
In gear position B, the paddles will not activate
automatically.

442 Shiftlock
The automatic transmission's shiftlock function
helps prevent inadvertently moving the gear
selector between different positions.
Automatic shiftlockThe automatic shiftlock has a separate safety
system.
From Park - P
To move the gear selector from the P position,
the brake pedal must be depressed and the igni-
tion in mode II.
From Neutral - N
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 selector will
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.
Messages in the instrument panelIf the gear selector is locked in position, a mes-
sage will appear in the instrument panel, e.g.
Gear lever Press brake pedal to activate
gear lever.
There is no mechanical shiftlock function.

• Gear selector positions for automatic trans-
missions (p. 439) The kickdown function
Kickdown is used when maximum acceleration is
needed, e.g. when passing. When the accelerator pedal is depressed all the
way to the floor (past the normal full accelerator
position), the transmission will automatically
engage kickdown, i.e. immediately shift down to a
lower gear.
If the accelerator pedal is released from the kick-
down position, the transmission will automatically
shift up again.
Safety function
The transmission control module is equipped with
a downshift protection feature to help prevent the
engine from overheating.
In some conditions, the transmission will prevent
downshifting/kickdown if this would lead to such
high engine speed (rpm) that the engine could
be damaged. If the driver still attempts downshift-
ing or kickdown at a high rpm, nothing will hap-
pen and the original gear will remain selected.
With kickdown, the vehicle can downshift one or
more steps at a time depending on the engine
speed. The vehicle upshifts when the engine rea-
ches its maximum rpm to prevent engine dam-
age.

and indicates when another gear should be
selected to optimize fuel economy. For eco-friendly driving when manually shifting, it
is important to use the correct gear and to shift
