STARTING AND DRIVING
407
The engine auto-starts while the brake pedal is depressed
In the following situations, the engine will auto-start even if the brake pedal isdepressed: High levels of condensation on the insideof the windows.
The climate system settings and theactual climate in the passenger compart-ment differ.
The brake pedal is pumped repeatedly.
The hood is open.
The vehicle begins to roll or increasesspeed slightly if the engine auto-stoppedbefore the vehicle was at a standstill.
The driver's seat belt is unbuckled with thegear 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
D. An audible signal and a text
message informs the driver that the igni-tion is on.
WARNING
Do not open the hood if the engine has auto-stopped. Turn off the engine byswitching off the ignition before lifting thehood.

Leveling control * and suspension
Self-leveling and suspension functions are controlled automatically.
Rear leveling control keeps the rear section of the vehicle at the same height regardless ofload. Leveling control may also remain activewhen the vehicle is parked.
Shock absorbers (Four-C)On vehicles equipped with Four-C, the shockabsorbers are adapted to the selected drive mode and the current vehicle speed. Theshock absorbers are normally set to help opti-mize comfort and are adjusted continuouslyaccording to the road surface and the vehicle'sacceleration, braking and cornering.
TransportingWhen transporting the vehicle on a ferry, trainor truck, only secure (lash) the vehicle aroundthe tires, not using any other parts of the chas-sis. Changes in the pneumatic suspension
may occur during transport, which couldadversely affect the lashing and result in dam-age.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. Observe the following rules:
For lower fuel consumption, activate
Ecodrive mode.
Use the Eco Coast function in drive mode
Eco - engine braking is deactivated, allow-
ing the vehicle's kinetic energy to be used to roll greater distances.
Use gear
D as often as possible and avoid
using the kick-down function.
For manual gear shifting, use the highestpossible gear for the current traffic situa-tion and road conditions - fuel consump-tion is reduced at lower engine speeds (rpm). Use the gear indicator 13
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking.
Fuel consumption is increased at highspeeds - air resistance increases withspeed.
The trip computer's current fuel consump-tion indicator can help promote more fuel-efficient driving.
Do not warm up the engine by idling. It isbetter to begin driving normally immedi-ately after starting the engine. A coldengine uses more fuel than a warmengine.
Whenever possible, avoid using the vehi-cle to drive short distances. The enginedoes not have time to reach a normaloperating temperature and this leads toincreased fuel consumption.
Use engine braking to brake the vehicle,when this is safe for other road users.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect fuelconsumption - consult a retailer for adviceon suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.

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.
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 mainte-nance schedule.

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 are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
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.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the 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.

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.

Driving through standing water
It may be necessary to drive the vehicle through standing water, e.g. deep puddles orflooding on the road. This must be done withgreat caution.
The vehicle can be driven through water up to a depth of 25 cm (9 in) at no more than walk-ing speed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When youhave passed the water, press lightly on thebrake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc.can make the brake linings slippery, resultingin delayed braking effect. If the vehicle is equipped with contacts for an electric heater or trailer coupling, cleanthese after driving in water or mud.
Do not allow the vehicle to stand in waterup to the sills any longer than absolutelynecessary. This could result in electricalmalfunctions.
CAUTION
Engine damage could occur if water enters the air cleaner.
If water enters the transmission, thelubricating ability of the oils is reducedand the service life of these systems isshortened.
Damage to any component, engine,transmission, turbocharger, differentialor its internal components caused byflooding, vapor lock or insufficient oil isnot covered under warranty.
If the engine stalls while the vehicle isin water, do not attempt to restart it.Have the vehicle towed out of thewater to a workshop. An authorizedVolvo workshop is recommended. Riskof engine failure.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.
