ECO
• Adapt the vehicle for more fuel-efficient and eco-friendly driving with Eco mode.
In this mode, the Start/Stop function is activatedand certain climate settings are reduced. The instrument panel has an ECO gauge to facili- tate fuel-efficient driving.
DYNAMIC
• Dynamic mode is designed to provide sport- ier driving characteristics and a faster accel-eration response.
Gear shifting will be faster and more distinct andthe transmission will prioritize gears with a highertraction force. Steering response is faster and suspension is stiffer 3
to help reduce body roll when cornering.
The Start/Stop function is deactivated.
INDIVIDUAL
• Customizes drive mode to personal preferen- ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv- ing characteristics. These settings will be stored in your driver profile. Individual drive mode is only available if it has been activated in the center display.Settings view 4

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.

Vehicles equipped with drive mode controls in the tunnel console have a function button forEco drive mode in the center display's Functionview.
When the engine is switched off, ECO mode is deactivated and must therefore be reactivated each time the engine is started. ECO will be dis-
played in the instrument panel when the function is activated.

Start/Stop function
Start/Stop is a function that temporarily switches off the engine when the vehicle has stopped,e.g. at a traffic light or in heavy traffic, and thenstarts it again automatically when the brakepedal is released.
The Start/Stop function reduces fuel consump- tion, which helps to reduce exhaust emissions. The system makes it possible to drive more eco- nomically and climate-smart by letting the engineauto-stop when appropriate.

Driving with the Start/Stop function
Start/Stop is a function that temporarily turns off the engine when the vehicle is stationary andthen automatically starts it again when the vehi-cle starts moving.
The Start/Stop function is available when the engine is started and can be activated if certainconditions are met. The instrument panel indi-cates if the function is available, active or notavailable. All of the vehicle's ordinary systems, such as lighting, radio, etc. function normally when theengine has been auto-stopped. Certain functionsmay be temporarily reduced, however, such asthe climate system's blower speed or extremelyhigh audio system volume.
Auto-stopTo auto-stop the engine:
• Stop the vehicle by applying the brakes andkeep the brake pedal depressed. The enginewill auto-stop.
In Eco or Comfort 5
drive mode, the engine may
auto-stop before the vehicle has completely stop-ped. With Adaptive Cruise Control or Pilot Assist acti- vated, the engine will auto-stop after approxi-mately three seconds.
Auto-startThe following conditions must be met for theengine to auto-start. • Release the brake pedal. The engine will auto-start and the vehicle can be driven. Onan uphill gradient, Hill Start Assist (HSA) willactivate to help prevent the vehicle from roll-ing backward.
• When Auto-hold is activated, auto-start willbe delayed until the accelerator is pressed.
• When Adaptive Cruise Control or Pilot Assistare activated, the engine will auto-start whenthe accelerator pedal is depressed or the
button on the left-side steering wheel
keypad is pressed.
• Maintain pressure on the brake pedal and press the accelerator pedal. The engine willauto-start.
• On a downhill gradient: Release the brakepedal slightly so that the vehicle begins toroll. The engine will auto-start after a slightincrease in speed.

If any condition is not met, this will be indicated in the instrument panel.
The engine does not auto-stopThe engine will not auto-stop if: •the vehicle has not reached a speed of ca 10 km/h (6 mph) after starting.
• after several auto-stops, the speed mustagain exceed approximately ca 10 km/h(6 mph) before the next auto-stop.
• the driver's seat belt is unbuckled.
• the start battery's charge is below the mini-mum level.
• the engine is not running at its normal oper-ating temperature.
• the ambient temperature is under approxi-mately -5 °C (23 °F) or over approximately30 °C (86 °F).

• the climate system settings and the actualclimate in the passenger compartment differ.
• the vehicle is backing up.
• the start battery's temperature is above orbelow the permitted limits.
• the driver is turning the steering wheel hard. •

• driving at high altitude and the engine hasnot reached its normal operating tempera-ture.
• ABS has been activated.
• hard braking (even if the ABS system hasnot been activated).
• many starts during a short period of timehave triggered the starter motor's overheat-ing protection.
• a trailer's electrical system is connected tothe vehicle's electrical system.
• the transmission is not running at its normaloperating temperature.
• The gear selector is in mode
M (±).
The engine does not auto-startThe engine will not auto-start after an auto-stopif: • the driver is not wearing a seat belt, the gear selector is in the
P position and the driver's
door is open. The engine must be started normally.
The engine auto-starts while the brake
pedal is depressed
In the following situations, the engine will auto-start even if the brake pedal is depressed: •
High levels of condensation on the inside ofthe windows.
• the climate system settings and the actualclimate in the passenger compartment differ.
• Electrical current consumption is temporarilyhigh or the start battery's charge is below theminimum level.
• The brake pedal is pumped repeatedly.
• The hood is open.
• The vehicle begins to roll or increases speedslightly if the engine auto-stopped before thevehicle was at a standstill.
• The driver's seat belt is unbuckled with the gear selector in the
D or N positions.
• The gear selector is moved from
D to R or M
( ± ).
• The driver's door is opened with the gearselector in

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. •
Fuel consumption is increased at highspeeds - air resistance increases with speed.
• Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
• Maintain the correct pressure in the tires andcheck pressure regularly.
• The type of tires used could affect fuel con-sumption - consult a retailer for advice onsuitable tires.
• Do not use winter tires after the winter sea-son has ended.
• Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
• Avoid driving with the windows open.
• Using the trip computer's fuel consumptionindicators can help you learn how to drivemore economically.
Other factors that decrease fuel
consumption
• Dirty air cleaner.
• Dirty engine oil and clogged oil filter.
• Incorrect front-end alignment.
• Incorrect wheel alignment.
Some of the above items and others are checked as part of Volvo's standard maintenance sched-ule.
