STARTING AND DRIVING
* Option/accessory.421
•
On a level road, the vehicle's actual speed may differ from the set speed when cruisecontrol is active and the vehicle is coasting.
• On a steep uphill gradient, the vehicle'sspeed is reduced until the transmissiondownshifts. Reduced acceleration is then ini-tiated in order to reach the set speed.
• On a downhill gradient in which the vehicle iscoasting, the vehicle's actual speed may beslightly above or below the set speed. Thefunction uses engine braking to keep the setspeed. If necessary, the normal brakes arealso applied.
ECO gauge in the instrument panelThe ECO gauge indicates how economical cur-rent driving is:
• A low reading in the green area of the gaugeindicates economical driving.
• A high reading is shown when driving is noteconomical, e.g. heavy braking or rapid accel-eration.
The ECO gauge also has an indicator showinghow a reference driver would drive in the samedriving situation. This is shown by the shortpointer in the gauge.

ECO ClimateIn Eco mode, ECO climate is automatically acti- vated in the passenger compartment to helpreduce energy consumption.
NOTE
When the ECO function is activated, settings for certain climate system and electricity con-suming functions are reduced. Some of thesesettings can be reset manually, but full func-tionality will only be restored by switching off the ECO function 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.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applicable speed limit regulations.
Preparations and towing
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
• Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
•
Ignition mode
II must be active – all air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral ( N) and
release the parking brake. If the battery charge level is too low, it may not be possible to release the parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.
