Adjustable air vents
There are 6, 8 * or 10 * adjustable air vents in the
passenger compartment, depending on the cli- mate system in the vehicle and the number ofseats.
Location of the air vents
2-zone system: four vents on the dashboard and one on each of the pillars between thefront and rear doors.
4-zone system *: two additional vents on the
rear side of the tunnel console.

STARTING AND DRIVING
360
Selecting a drive mode
1.Press the DRIVE MODE control in the tunnel
console.
> A pop-up menu will open in the center display.
2. Roll the control upward or downward to scroll to the desired drive mode. A drive mode can also be selected by tap- ping its button on the center display.
3. Press the control again to select it.
Available drive modes
COMFORTThis is the default mode. When the engine is started, COMFORT 5
drive
mode will be selected and the Start/Stop func- tion will be activated. This setting offers driving comfort and light steering.
ECOECO drive mode is designed to help promote fuel-efficient driving. In this mode, Start/Stop is activated, ground clearance is lowered to help reduce wind resis-tance and certain climate system functions willbe reduced. There is an ECO guage in the instrument panel to indicate the current level of fuel-efficiency. Seealso the article "ECO drive mode."
OFF ROADThis mode helps maximize the vehicle's capacity to traverse difficult terrain or poor roads. In OFF ROAD, ground clearance is maximized, the steering is light, All Wheel Drive and HillDescent Control are activated and a compassand altimeter will be displayed in the instrumentpanel. Start/Stop is deactivated. This drive mode can only be activated at low speeds (the permissable speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and anotherdrive mode will be activated. This mode is not intended for normal street driv- ing.
CAUTION
OFF ROAD drive mode may not be used if the vehicle is towing a trailer without an elec-trical connection. This could result in damageto the pneumatic suspension system's bel-lows.
Due to the increased ground clearance, if the OFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.
DYNAMICDYNAMIC driving mode is designed to provide sportier driving characteristics. Steering response will be more immediate, the suspension will be stiffer and low ground clear-ance will help reduce body roll when cornering.Start/Stop will be deactivated.

If the OFF ROAD mode was selected when the engine was switched off, it will also restart in this mode.

ECO drive mode
The Eco drive mode is a function designed to give the driver the opportunity to drive more eco-nomically and to help reduce fuel consumption.
When this mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points
• The engine management system and accel- erator pedal response
• Eco Coast functionality is activated: enginebraking is disabled at speeds betweenapprox. 40 and 85 mph (65 and 140 km/h)
• Climate system settings: certain functionswill be temporarily reduced or deactivated
• The suspension's self-leveling function
* low-
ers ground clearance to help reduce windresistance
• Information is shown in an ECO gauge in theinstrument panel to help promote more eco-nomical driving
NOTE
When Eco is activated, several climate system parameters are changed and the function ofcertain current-consuming systems will bereduced. Some of these functions can be restarted manually but full functionality will not berestored until Eco is deactivated.
Selecting ECO modeWhen the engine is switched off, ECO mode is deactivated and must be reactivated each time the engine is started.
ECO will appear in the
instrument panel when the function is activated.
Via Function view
Select Driving mode ECO in
the center display's Function view. A green indicator light inthe button shows that the func-tion is activated.

1.
Press the DRIVE MODE control.
> A pop-up menu will open in the center display.
2. Roll the control upward or downward to scroll to the desired drive mode and 3. Press the control again to select it. A drive
mode can also be selected by tapping its button on the center display.
Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle to roll freely. When the driver releases the accelerator pedal, the transmission is automatically disengagedfrom the engine to allow the vehicle to roll as faras possible, which helps reduce fuel consump-tion. This feature is primarily intended to be used in driving situations where the vehicle can roll freely,such as down gentle hills or when a decrease inspeed is expected, such as when approaching anintersection or a traffic light. Eco Coast enables proactive driving with as little braking as possible. Depending on the driving situation, Eco and Eco Coast can be used in different ways to helpreduce fuel consumption: • With Eco activated
: this enables Eco Coast,
which allows the vehicle to roll freely for as
far as possible when the driver releases the
accelerator pedal (e.g., when approaching a traffic light or intersection).
or
• With Eco deactivated
: engine braking can
be used when the vehicle will only roll for

WHEELS AND TIRES

WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking (straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.

Start battery
The start (main) battery is used to power the starter motor and other electrical componentsand systems. The start battery should only be replaced by a trained and qualified Volvo service technician.
The vehicle has an alternating current generator. The start battery is called an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles with carbon dioxide-reducingfunctions such as Start/Stop and regenerativecharging, and to support the vehicle's variouselectrical systems and functions. The service life of a battery is affected by factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery
