Available drive modes
COMFORT
This is the default mode. When the engine is started, COMFORT drive mode will be selected and the Start/Stop func-tion will be activated. This setting offers drivingcomfort, light steering and relatively soft suspen-sion.
ECO
ECO drive mode is designed to help promote fuel-efficient driving. In this mode, Start/Stop is activated and certain climate system functions will be reduced. There is an ECO gauge in the instrument panel to indicate the current level of fuel-efficiency. Seealso the article "ECO drive mode."
DYNAMIC
Dynamic drive mode is designed to provide
sportier driving characteristics. Gear shifting will be faster and more distinct and will occur athigher rpm. Steering response will be more immediate and the suspension will be stiffer 3
to help reduce
body roll when cornering.
Start/Stop will be
deactivated.

ECO drive mode
The Eco drive mode is a function designed to give the driver the opportunity to drive more eco-nomically and to help reduce fuel consumption.
When this mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points
• The engine management system and accel-erator pedal response
• Eco Coast functionality is activated: enginebraking is disabled at speeds betweenapprox. 40 and 87 mph(65 and 140 km/h)
• Climate system settings: certain functionswill be temporarily reduced or deactivated
• Information is shown in an ECO gauge in theinstrument panel to help promote more eco-nomical driving
NOTE
When Eco is activated, several climate system parameters are changed and the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Selecting ECO modeWhen the engine is switched off, ECO mode is deactivated and must be reactivated each time the engine is started.
ECO will appear in the
instrument panel when the function is activated.

Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle to roll freely. When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine to allow the vehicle to roll as faras possible, which helps reduce fuel consump-tion. This feature is primarily intended to be used in driving situations where the vehicle can roll freely,such as down gentle hills or when a decrease inspeed is expected, such as when approaching anintersection or a traffic light. Eco Coast enables proactive driving with as little braking as possible. Depending on the driving situation, Eco and Eco Coast can be used in different ways to helpreduce fuel consumption: • With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• With Eco deactivated
: engine braking can
be used when the vehicle will only roll for

378 a short distance
(in heavy traffic, etc.) or
when driving down hills .
To help keep fuel consumption as low as possi- ble, Eco Coast should not be used in traffic situa-tions where the brakes have to be used fre-quently.
Activating Eco Coast
Eco Coast is activated when the accelerator pedal is released completely if:
• Eco is activated
• The gear selector is in
D
• The vehicle's speed is between approxi-mately 40 and 87 mph(65 and 140 km/h)Always observe posted speed limits
• The gradient of a down-slope is less thanapproximately 6%
COASTING will appear in the instrument panel
when Eco Coast is being used.
Limitations
Eco Coast is not available if:
• The engine and/or transmission have not reached their normal operating temperature
• Cruise control is activated
• The gear selector is moved from
D to " +/-"
for manual shifting
• The vehicle's speed is not within the40 and 87 mph(65 and 140 km/h) range •
The gradient of a down-slope is more thanapproximately 6%
• The steering wheel paddles
* are used for
manual shifting
Deactivating and turning off Eco Coast
In certain situations, it may be advisable to switch off the Eco Coast function, such as:
• When driving down steep hills, in order to uti-lize engine braking
• Prior to passing another vehicle, in order todo so as safely as possible
Deactivating Eco Coast (and reactivating enginebraking) can be done in the following ways: • Move the gear selector to the manual "
+/–"
position
• Change gears using the steering wheel pad- dles
*
• Press the brake or accelerator pedal
Turn the function off by changing drive modes * or
by turning ECO off in the center display's Func- tion view. The vehicle will roll for short distances even if Eco Coast is turned off to help conserve fuel.However, for the best fuel economy, the functionshould be used as much as possible.

The ECO gauge also has an indicator showinghow a "reference" driver would drive in the samesituation. This is indicated by a diamond in thegauge.
Eco climate
In the Eco drive mode, eco climate is automati-
cally activated in the passenger compartment to help minimize energy consumption. To restart the climate system functions that may have been reduced, press the
AUTO or defroster
buttons. In order to return to full functionality for all of the systems that may have been reduced to helpimprove economical driving, select another drivemode or adapt the climate system functions using the
Individual mode to full functionality.

Start/Stop
Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving,for instance in heavy traffic or at a traffic light, tohelp reduce fuel consumption. The engine startsagain automatically when the brake pedal isreleased.
Start/Stop is one of several fuel-conserving fea- tures that also help reduce emissions. This feature helps make it possible to drive more economically by allowing the engine to auto-stopin certain situations.

Using the Start/Stop function Start/Stop is a function that temporarily switches off the engine when the vehicle is not moving,for instance in heavy traffic or at a traffic light, tohelp reduce fuel consumption. The engine startsagain automatically when the brake pedal isreleased.
Start/Stop is available when the engine has been started. The instrument panel will indicate if thefunction is available/unavailable/active. All of the vehicle's normal systems such as light- ing, infotainment, etc., function normally when theengine has auto-stopped. However, certain func-tions, such as climate system blower speed orvery high infotainment system volume, will betemporarily reduced.
Auto-stopThe following conditions must be met for theengine to auto-stop:
• Stop the vehicle by applying the brakes andkeep the brake pedal depressed. The engine will auto-stop. If the COMFORT 5
or ECO driv-
ing modes are activated, the engine can auto-stop before the vehicle has come to astandstill.
If the
