Climate comfort retaining function
The climate in the passenger compartment can
be maintained when the vehicle is parked, e.g. if
the engine is turned off but the driver or passen-
gers remain in the vehicle.
This function can only be direct-started.
The function utilizes several of the vehicle's sys-
tems: Residual heat from the engine is used to
help heat the passenger compartment to a
comfortable temperature.
In warm weather, the ventilation system cools
the passenger compartment by blowing air in
from outside.
NOTE Climate comfort maintenance will be deacti-
vated if the vehicle is locked from the outside
in order to avoid using residual engine heat
unnecessarily. This function is intended to be
used to maintain climate comfort when the
driver or a passenger remains in the vehicle
after the engine is turned off.

Heater
The heater helps the engine and passenger
compartment reach the correct temperature
before and while driving.
The heater has two sub-functions: Parking heater - heats the passenger com-
partment as needed when the parking cli-
mate's preconditioning is activated.
Auxiliary heater - heats the passenger com-
partment and engine while driving.
The heater is a high-voltage coolant heater and is
mounted in the front right-side wheel housing.
Battery and chargingThe heater is powered by the vehicle's hybrid bat-
tery. If the charge level in the hybrid battery is too
low, the heater will switch off automatically and a
message will be displayed in the instrument
panel.
NOTE Make sure that the battery has sufficient
charge if the heater must be used.

454 Starting and stopping the
combustion engine in Twin Engine
vehicles
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. When driving on only the electric
motor, the vehicle may automatically start the
combustion engine due to outside circumstan-
ces, e.g. low ambient temperatures. This is com-
pletely normal. The combustion engine will also
always start when the hybrid battery is nearly
fully discharged.
Climate settings at low temperaturesAt low ambient temperatures, the combustion
engine will sometimes start automatically to help
achieve the desired passenger compartment
temperature and air quality. The amount of time
the combustion engine is running can be affec-
ted by:
lowering the temperature
reducing blower speed
activating Pure drive mode.
Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, the
electric motor's driving range and power may be
reduced and affect how often the combustion
engine automatically starts.
Emission control systemTo help ensure that the emission control system
functions optimally, the combustion engine will
run for several minutes after it is started. The
amount of time the combustion engine needs to
be used varies depending on the temperature of
the three-way catalytic converter.

plify the driving experience in certain types of sit-
uations.
Drive modes enable easy access to the vehicle's
many functions and settings in different driving
situations. The following systems are adapted to
help optimize driving characteristics in each drive
mode:

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.

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
