Available drive modes
WARNING Keep in mind that the vehicle does not emit
any engine noise when using the electric
motor and may therefore be difficult to detect
for children, pedestrians, cyclists or animals.
This is particularly true at low speeds, e.g. in
parking lots.
WARNING
Do not leave the vehicle in an unventilated
area with a drive mode activated and the com-
bustion engine switched off. The engine will
start automatically if the charge level in the
hybrid battery is low and the resulting exhaust
gases can be very harmful to people and ani-
mals.
HYBRID
This is the default mode in which the electric
motor and combustion engine work together.
The vehicle starts in Hybrid mode. The control
system uses both the electric motor and the gas-
oline engine - separately or in tandem - and cal-
culates optimal utilization with regard to perform-
ance, fuel consumption and comfort. At high
speeds, ground clearance is automatically low-
ered 3
to reduce air resistance. Driving capacity on
the electric motor alone is determined by factors such as the hybrid battery's charge level, the
need for heat/cooling in the passenger compart-
ment, etc.
If there is sufficient charge in the battery, it is
possible to drive solely on electric power. When
the accelerator pedal is pressed, only the electric
motor will be activated until the battery reaches a
certain charge level. Above this level, the current
in the battery cannot supply the power requested
by the accelerator pedal and the combustion
engine will start.
When the hybrid battery's charge level is low, the
combustion engine will start more frequently to
save the remaining current in the battery. Charge
the hybrid battery from a 120-240 volt outlet
using a charging cable, or activate
Charge in
Function view to reset the option of only using
the electric motor.
This drive mode is designed for low energy con-
sumption with an optimized mix between the
electric motor and gasoline engine, without com-
promising on climate comfort or driving experi-
ence. When faster acceleration is requested by
the driver, the electric driveline will be utilized to
help provide maximum additional power. The
vehicle also monitors the driving conditions and
automatically engages all-wheel drive if neces-
sary. All-wheel drive and extra electric power are
always available regardless of the battery's
charging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge will
be displayed in the instrument panel. The gauge
will indicate the amount of electrical current
required when the driver depresses the accelera-
tor pedal. The marker between the lightning and
the drop shows how much current is available. The instrument panel gauge when both the electric
motor and the combustion engine are being used.
The instrument panel also shows how
much current is being restored to the
battery (regenerated) during light brak-
ing. 3

PURE
Uses the electric motor only, with the lowest
possible energy consumption and carbon
dioxide emissions.
This drive mode maximizes the use of the hybrid
battery. Ground clearance is lowered 3
to reduce
air resistance and certain climate system func-
tions are reduced to provide the longest possible
driving distance using only electricity.
Pure mode is available when the hybrid battery is
sufficiently charged. Even in Pure mode, the com-
bustion engine will start if the charge level in the
battery gets too low. The combustion engine will
also start
if the vehicle's speed goes above 125 km/h
(78 mph)
if the driver requests more power than the
electric motor can provide
if factors such as cold weather affect the
system or components.
This drive mode is optimized for maximum driving
distance with electric propulsion and is primarily
intended for use in city driving. Pure helps pro-
vide the lowest possible consumption even when
the hybrid battery is fully discharged. ECO climate
is activated to control the climate in the passen-
ger compartment, and in slippery road conditions
slightly more wheel spin may be permitted before
all-wheel drive is automatically activated.
ECO Climate
In Pure mode, ECO climate is automatically acti-
vated in the passenger compartment to help
reduce energy consumption.
NOTE When the
Pure drive mode is activated, set-
tings for certain climate system and electricity
consuming functions are reduced. Some of
these settings can be reset manually, but full
functionality will only be restored by leaving
Pure mode or adapting the Individual drive
mode to full climate system functionality. If condensation forms on the windows, tap the
max defroster button, which will function normally.
OFF ROAD
Maximizes the vehicle's ability to traverse dif-
ficult terrain or poor roads.
In this mode, ground clearance 3
is high, steering
is light, and all-wheel drive and Hill Descent
Control are activated.
This drive mode is only available at low speeds,
up to 40 km/h (25 mph). If this speed is excee-
ded, Off road mode will be cancelled and AWD
mode will be activated instead. All-wheel drive requires both the combustion and
electric motor to be in continuous operation,
which results in higher fuel consumption.
In Off road mode, a compass will be displayed
between the speedometer and the tachometer in
the instrument panel. The permissible speed
range will be shown in the speedometer.

This drive mode is optimized for maximum control
when driving at low speeds on very poor roads or
difficult terrain. It raises the chassis
3
, reduces
driveline throttle response, and locks the vehicle
in all-wheel drive. The Hill Descent Control func-
tion facilitates controlled driving on steep down-
grades.
NOTE This drive mode is not designed to be used
for normal street driving.
NOTE
Due to the increased ground clearance, if the
OFF ROAD mode was selected when the
engine was switched off, the suspension will
lower when the engine is restarted.
CAUTION
Do not use the OFF ROAD drive mode when
towing a trailer without an electrical connec-
tion. This could result in damage to the pneu-
matic suspension system's bellows.
AWD
Improves the vehicle's traction and handling
by increasing all-wheel drive. This drive mode locks the vehicle in all-wheel
drive. An optimal distribution between front and
rear axle torque helps provide the best possible
control, stability and traction, e.g. on slippery
roads or when towing a heavy trailer or another
vehicle. The AWD drive mode is always available
regardless of the hybrid battery's charge status.
Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
In the other drive modes, the vehicle automati-
cally adapts the need for all-wheel drive accord-
ing to the road surface, and can activate the elec-
tric motor or start the combustion engine as nee-
ded.
POWER
Power mode is designed to provide sportier
driving characteristics and a faster accelera-
tion response.
This drive mode maximizes the combined power
from the combustion engine and the electric
motor by providing power to both the front and
rear wheels. Gear shifting will be faster and more
distinct and the transmission will prioritize gears
with a higher traction force. Steering response is
faster, suspension is stiffer and ground clearance
is lower 3
to help reduce body roll when cornering. Both the combustion engine and the electric
motor are engaged to enable all-wheel drive,
which results in higher fuel consumption.
This drive mode is optimized for maximum per-
formance and throttle response. It changes the
throttle response, gear shifting program and
turbo boost system. Chassis settings and steer-
ing and brake response are also optimized. The
Power drive mode is always available regardless
of the hybrid battery's charge status.

Using the electric or combustion
engine
An advanced control system determines the dis-
tance that the vehicle can be driven on the com-
bustion engine, electric motor, or both at the
same time.
Its primary function is to use the motor/engine
and the current available in the hybrid battery as
efficiently as possible based on the characteris-
tics of the various drive modes and the power
output requested by the driver by pressing the
accelerator pedal.
In certain cases, temporary limitations in the sys-
tem or mandatory functions to help maintain a
low overall emissions level may result in greater
use of the combustion engine. 4

460 Energy distribution in hybrid mode
using map data*
The Hybrid drive mode is the vehicle's default
drive mode in which the electric motor and the
combustion engine work separately or together
in hybrid mode. If a destination has been
selected in the navigation system*, the Predictive
Efficiency 5
function can use map data to effec-
tively distribute the electric power throughout the
trip.
This can lower fuel consumption in comparison
with normal hybrid mode, in which the vehicle first
runs on electricity and then switches to the com-
bustion engine when the hybrid battery is dis-
charged.
If the distance to the destination is greater than
the calculated range on the electric motor, the
function will distribute electric power optimally for
the entire trip. This makes it possible to avoid sit-
uations in which normal hybrid mode would oth-
erwise use a large portion of the electric power
to e.g. use the electric motor at high speeds on a
highway and then use the combustion engine at
lower speeds during city driving.
The greatest fuel savings are attained when the
trip begins on a highway, is between 50 and 100
km (30 and 60 miles) long, and the hybrid battery
is fully charged at the start of the trip.
Requirements for the functionCertain conditions must be met for the function
to be possible: A destination must be set in the navigation
system and the distance to the destination
must be longer than the possible range
using only the electric motor.
Hybrid drive mode must be selected.
The
Hold and Charge functions must be
disabled.
The hybrid battery must be charged.
Usage tipsIf you commute and it is not possible to charge
the vehicle at work, enter your workplace as a
waypoint and your home as the destination. Dis-
charging of the hybrid battery will then be distrib-
uted over the entire commute to and from work.
Add similar commutes, i.e. the route between two
charges, as
Favorites in the navigation system to
facilitate access.

Leveling control* and suspension
The vehicle's leveling control system adjusts the
suspension and shock absorbers automatically
to help provide good comfort and control while
driving. Leveling can also be controlled manually
to facilitate loading or getting in and out of the
vehicle.
Pneumatic suspension and shock
absorbers
The system is adapted to the selected drive
mode and vehicle speed. The pneumatic suspen-
sion reduces the vehicle's ground clearance at
higher speeds to reduce air resistance and
increase stability. The shock absorbers are nor-
mally set to provide the best possible comfort
and are adjusted continuously according to the
road surface and the vehicle's acceleration, brak-
ing and cornering. The instrument panel indicates
when the suspension level is
being adjusted.The following apply if a door or the tailgate is
opened:
If a door is opened, the level can only be
adjusted upwards.
If the tailgate is open, the level can only be
adjusted downwards.
ParkingWhen parking, make sure that there is adequate
space above and below the vehicle since ground
clearance may vary depending on e.g. ambient temperature, how the vehicle is loaded, if loading
mode is used, which drive mode is selected after
the engine is started, etc.
The level may also be adjusted a period after the
vehicle is parked. This is to compensate for any
height changes that may occur due to tempera-
ture changes in the air springs when the vehicle
cools.
TransportingWhen transporting the vehicle on a ferry, train or
truck, only secure (lash) the vehicle around the
tires, not using any other parts of the chassis.
Changes in the pneumatic suspension may occur
during transport, which could adversely affect the
lashing and result in damage.
