Changing drive mode Select the drive mode that is adapted to the current driving conditions. The drive mode is changed using the control in the tunnel console.
Keep in mind that not all drive modes are available in all situations. To change drive mode:
1. Press the
DRIVE MODE control.
> A pop-up menu will appear in the cen- ter display.
2. Roll the wheel upward or downward to the desired drive mode. 3. Press the drive mode control or tap its
button in the center display to confirm the selection.
> The selected drive mode is shown inthe instrument panel.

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 sepa-rately or together in hybrid mode. If a destina-tion has been selected in the navigation sys- tem *, the Predictive Efficiency 8
function can
use map data to effectively distribute the electric power consumption throughout thetrip.
This can lower fuel consumption in compari- son with normal hybrid mode, in which thevehicle first runs on electricity and thenswitches to the gasoline engine when thehybrid battery is discharged.
FunctionIf the distance to the selected destination isgreater than the calculated range on the elec-tric motor, the function will distribute the elec-tric power to make consumption as energy-efficient as possible throughout the trip. Thismakes it possible to avoid situations in whichnormal hybrid mode would otherwise use alarge portion of the electric power to e.g. usethe electric motor at high speeds on a high-way and then use the combustion engine atlower speeds during city driving. The greatest fuel savings are achieved when
the trip begins on a highway
the trip is between 50 and 100 km (30and 60 miles) long
the hybrid battery is fully charged at thestart of the trip.
Requirements for the functionCertain conditions must be met for the func-tion to be possible:
A destination must be set in the navigationsystem and the distance to the destinationmust be longer than the possible rangeusing 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 work-place as a waypoint and your home as thedestination. Discharging of the hybrid batterywill then be distributed over the entire com-mute 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
Self-leveling and suspension functions are controlled automatically.
Rear leveling control keeps the rear section of the vehicle at the same height regardless ofload. Leveling control may also remain activewhen the vehicle is parked.
Shock absorbers (Four-C)On vehicles equipped with Four-C, the shockabsorbers are adapted to the selected drive mode and the current vehicle speed. Theshock absorbers are normally set to help opti-mize comfort and are adjusted continuouslyaccording to the road surface and the vehicle'sacceleration, braking and cornering.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspension
may occur during transport, which couldadversely affect the lashing and result in dam-age.

In certain situations, this function must be turned off, e.g. before the vehicle is raised using a jack *. The level difference caused by
raising the vehicle with a jack could cause problems with the pneumatic suspension. Turning off the function in the center display:1. Tap

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. To help achieve the greatest distance with the lowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging it into an electrical outlet. Make it a habit toalways begin trips with the hybrid batteryfully charged.
Locate charging stations along your route.
If possible, choose parking spots withcharging stations.
NOTE
Charge the vehicle from the electricity grid as often as possible!
Preconditioning
Whenever possible, precondition the vehi- cle before driving by connecting thecharging cable to an electrical outlet.
Avoid parking the vehicle somewherewhere the interior will become too hot ortoo cold while the vehicle is parked. If pos- sible, park the vehicle in a climate-con-trolled garage.
During a short drive after passenger com-partment preconditioning, turn off thepassenger compartment fan or the airconditioning in a hot climate.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe hybrid battery.

Driving
Choose the Pure drive mode to help mini-
mize electric power consumption.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. This drive mode has thelowest power consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustionengine, especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will helprecharge the hybrid battery. A regenerativefunction is integrated in the brake pedaland can be augmented by the electricmotor's braking capacity when the gearselector is in mode
B.
Higher speeds increase energy consump-tion - air resistance increases with speed.
Activate the
Hold function in the Function
view at high speeds when traveling farther than is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the
Charge function to charge the hybrid bat-
tery. Charging the battery using the com- bustion engine increases fuel consump- tion and carbon dioxide emissions.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for adviceon suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal.Use the brakes instead.

Factors affecting electric motor range
A number of factors affect the electric motor's driving range. The ability to achieve along driving range varies according to theoutside conditions and to how the vehicle isdriven.
The certified value for the distance that can be driven using the electric motor should not beconsidered an expected driving range. Theactual range is dependent on a number of fac-tors.
Factors affecting driving rangeThe driver can influence some factors affectingdriving range, but not all. The longest range is achieved under very favorable conditions when all factors positivelyinfluence range.

Factors the driver cannot control
There are several outside conditions that affect range to varying degrees: the current traffic situation
driving short distances
topography
ambient temperature and headwinds
road conditions and road surface.
The table shows the approximate relationshipbetween ambient temperature and drivingrange with normal climate settings and withclimate settings turned off. Up to a certain limit, warmer ambient temper- atures increase the electric motor's drivingrange.
