Fuel gauge
The fuel gauge in the instrument panel shows the fuel level in the tank.
Fuel gauge in 12" instrument panel: The beige area in the fuel gauge indicates the amount of fuel left in the tank. When the fuel level is low and it is time to refuel, the fuel pump symbol will illuminate with anamber-colored light. The trip computer also indi-cates the approximate distance driven on the fuelremaining in the tank.
Fuel gauge in 8" instrument panel: The bars in the fuel gauge indicate the amount of fuel left in the tank. When the fuel level is low and it is time to refuel, the fuel pump symbol will illuminate with anamber-colored light. The trip computer also indi-cates the approximate distance driven on the fuelremaining in the tank. When the fuel level is criti-cally low, only an amber bar will be displayed.Refuel as soon as possible.

The trip computer includes the following gauges:
• Trip odometer
• Odometer
• Current fuel consumption •
Distance to empty tank
• Tourist - alternative speedometer
Unit standards for distance, speed, etc. can be changed via system settings in the center display.
Trip odometerThere are two trip odometers: TM and TA. TM can be reset manually and TA is reset auto- matically if the vehicle is not used for four hours. During a drive, the trip odometer registers data on:
• Mileage
• Driving time
• Average speed
• Average fuel consumption
The readings since the trip odometer's last resetare displayed.
OdometerThe odometer records the vehicle's total mileage.This reading cannot be reset.
Current fuel consumptionThis gauge shows the vehicle's fuel consumptionat that moment. The reading is updated aboutonce a second.
Distance to empty tankThe trip computer calculates the distance thatcan be driven on the fuel remaining in the tank. This calculation is based on average fuel con-sumption during the last 30 km (20 miles) andthe amount of fuel remaining in the tank. When the gauge displays "----", there is not enough fuel remaining to calculate the remainingmileage. Refuel as soon as possible.
NOTE
This may vary if your driving style changes.
An economical driving style will generally increase how far you can drive on a certainamount of fuel.
Tourist - alternative speedometerThe alternative digital speedometer makes it eas-ier to drive in countries where speed limit signsare shown in a different measurement unit thanthe one shown in the vehicle's gauges. When used, the digital speed is displayed in the opposite unit to that shown in the analog speed- ometer. If
mph is used in the analog speedome-
ter, the equivalent speed in km/h will be shown
in the digital speedometer.

Displaying trip statistics in thecenter display
Trip computer statistics can be displayed graphi- cally in the center display, providing an overviewthat facilitates more fuel-efficient driving.
Open the Driver performanceapp in the App view to display trip statistics. Each bar in the graph repre- sents a driving distance of 1kilometers, 10 kilometers or
100 kilometers (or miles). The bars are addedfrom the right as you drive. The bar at the far rightshows the data for the current trip. Average fuel consumption and total driving time are calculated from the most recent reset of thetrip statistics.

ECO drive mode
The Eco drive mode optimizes the vehicle's driv- ing characteristics for more fuel-efficient andeco-friendly driving.
Use this mode to save fuel and promote eco- friendly driving. When ECO mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points.
• Engine control and accelerator pedalresponse.
• Eco Coast functionality is activated andengine braking is disabled when the acceler-ator pedal is released at speeds between65 and 140 km/h (40 and 87 mph).
• Some of the climate system settings will bereduced or switched off.
• The suspension's self-leveling function
* will
lower ground clearance to help reduce windresistance.
• Information will be shown in the ECO gaugein the instrument panel to help promotemore eco-friendly and economical driving.
Coast function Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle's kinetic energy to be usedto roll greater distances. When the driver releasesthe accelerator pedal, the transmission is auto-matically disengaged from the engine. Engine speed is reduced to idling speed to reduce fuelconsumption. This function is most effective in driving situa- tions where the vehicle can roll freely for a longdistance, e.g. on roads with slight downgrades orwhen a decrease in speed is anticipated, such aswhen approaching an area with a lower speedlimit.
Activating Eco Coast
The function is activated when the accelerator pedal is fully released and the following condi-tions are met:
• Eco drive mode is activated.
• The gear selector is in
D.
• The vehicle's speed is approximately65-140 km/h (40-87 mph).
• The gradient of the downgrade is less thanapproximately 6%.
COASTING will be displayed in the instrument
panel when Eco Coast is being used.
Limitations
Eco Coast is not available if:
• The engine and/or transmission are not at normal working temperatures.
• The gear selector is moved from
D to manual
shifting mode.
• The vehicle's speed is not within the65-140 km/h (40-87 mph) range. •
The gradient of the downgrade is more thanapproximately 6%.
• The steering wheel paddles
* are being used
for manual shifting.
Deactivating and turning off Eco Coast
In certain situations, it may be advisable to deac- tivate or turn off Eco Coast so that engine brak-ing can be used. These situations might includedriving down steep hills or before passinganother vehicle to help ensure this can be doneas safely as possible. Deactivate Eco Coast by:
• Pressing the accelerator or brake pedal.
• Moving the gear selector to manual mode.
• Using the steering wheel paddles
* to shift.
Turn off Eco Coast by:
• Switching drive mode
* or switching off drive
mode Eco in Function view.
It is possible to roll short distances even without Eco Coast in order to help conserve fuel. How-ever, for the best fuel economy, Eco Coast shouldbe activated and used to roll longer distances.
Cruise control Eco CruiseWhen cruise control is activated in the Eco drivemode, the vehicle's acceleration and decelerationwill be slower than in other drive modes to helpfurther conserve fuel. Because of this, the vehi-cle's actual speed may be slightly above or belowthe set speed.

Economical driving
Drive economically and environmentally con- scious by thinking ahead, avoiding rapid startsand stops and adapting driving style and speedto the current traffic conditions.
Driving economically conserves natural resources
Observe the following rules:
• Do not warm up the engine by idling. It is better to begin driving normally immediately after starting the engine. A cold engine uses more fuel than a warm engine and is subject to increased wear.
• Whenever possible, avoid using the vehicle todrive short distances. The engine does nothave time to reach a normal operating tem-perature and this leads to increased fuelconsumption.
• Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking.
• For lower fuel consumption, activate Ecodrive mode.
• Use the Eco Coast function in drive mode Eco - engine braking is deactivated, allowing the vehicle's kinetic energy to be used to rollgreater distances.
• Use gear
D as often as possible and avoid
using the kick-down function.
