STARTING AND DRIVING
* Option/accessory.417
On a level road, the vehicle's actual speed may differ from the set speed when cruisecontrol is active and the vehicle is coast-ing.
On a steep uphill gradient, the vehicle'sspeed is reduced until the transmissiondownshifts. Reduced acceleration is theninitiated in order to reach the set speed.
On a downhill gradient in which the vehi-cle is coasting, the vehicle's actual speedmay be slightly above or below the setspeed. The function uses engine brakingto keep the set speed. If necessary, thenormal brakes are also applied.

The ECO gauge indicates how economical current driving is:
A low reading in the green area of thegauge indicates economical driving.
A high reading is shown when driving isnot economical, e.g. heavy braking orrapid acceleration.
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
activated in the passenger compartment to help reduce energy consumption.
NOTE
When the Eco drive mode is activated, set-
tings for certain climate system and elec- tricity consuming functions are reduced.Some of these settings can be reset man-ually, but full functionality will only be restored by switching off
Eco mode 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 nor-mally.

Economical driving
A more economical driving style can help lower fuel consumption.
Before driving
If possible, precondition the vehicle before driving.
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 start battery.
Avoid using idling to warm up the vehiclebefore driving.
The type of tires and inflation pressureused could affect energy consumption –consult an authorized Volvo retailer foradvice on suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
While driving
Activate Eco drive mode.
Use gear selector position
D as often as
possible.
When using manual gear shifting, drive using the highest possible gear. Use the gear indicator 14
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. Use engine braking if possi-ble.
Higher speeds increase energy consump-tion because air resistance increases withspeed.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Avoid driving with the windows open.
Do not use the accelerator pedal to keepthe vehicle stationary on an uphill gradi-ent. Instead, activate the auto-hold brakefunction at a standstill.
Use trip data to see current fuel consump-tion.
WARNING
Never turn off the engine while the vehicle is moving, e.g. when driving downhill. Thisdeactivates certain important systemssuch as power steering and brakes.
After driving
If possible, park in a climate-controlled garage.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights work
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
Check the condition and charge level ofthe start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
See separate section for engine oil recommen-dations.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–To charge the battery, start the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).

Jump starting using another battery If the start battery is discharged, current from another battery can be used to start the vehi-cle.
Jumper cable connecting points. Engine compart- ment appearance may vary depending on vehiclemodel and equipment level.
To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery using another battery:
1. Put the ignition in mode
0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts.
