Fuel gauge
The fuel gauge in the instrument panel shows the fuel level in the tank.
Fuel gauge in 12" instrument panel: The beige area in the fuel gauge indicates the amount of fuel left in the tank. When the fuel level is low and it is time to refuel, the fuel pump symbol will illuminate with anamber-colored light. The trip computer also indi-cates the approximate distance driven on the fuelremaining in the tank.
Fuel gauge in 8" instrument panel: The bars in the fuel gauge indicate the amount of fuel left in the tank. When the fuel level is low and it is time to refuel, the fuel pump symbol will illuminate with anamber-colored light. The trip computer also indi-cates the approximate distance driven on the fuelremaining in the tank. When the fuel level is criti-cally low, only an amber bar will be displayed.Refuel as soon as possible.

The trip computer includes the following gauges:
• Trip odometer
• Odometer
• Current fuel consumption •
Distance to empty tank
• Tourist - alternative speedometer
Unit standards for distance, speed, etc. can be changed via system settings in the center display.
Trip odometerThere are two trip odometers: TM and TA. TM can be reset manually and TA is reset auto- matically if the vehicle is not used for four hours. During a drive, the trip odometer registers data on:
• Mileage
• Driving time
• Average speed
• Average fuel consumption
The readings since the trip odometer's last resetare displayed.
OdometerThe odometer records the vehicle's total mileage.This reading cannot be reset.
Current fuel consumptionThis gauge shows the vehicle's fuel consumptionat that moment. The reading is updated aboutonce a second.
Distance to empty tankThe trip computer calculates the distance thatcan be driven on the fuel remaining in the tank. This calculation is based on average fuel con-sumption during the last 30 km (20 miles) andthe amount of fuel remaining in the tank. When the gauge displays "----", there is not enough fuel remaining to calculate the remainingmileage. Refuel as soon as possible.
NOTE
This may vary if your driving style changes.
An economical driving style will generally increase how far you can drive on a certainamount of fuel.
Tourist - alternative speedometerThe alternative digital speedometer makes it eas-ier to drive in countries where speed limit signsare shown in a different measurement unit thanthe one shown in the vehicle's gauges. When used, the digital speed is displayed in the opposite unit to that shown in the analog speed- ometer. If
mph is used in the analog speedome-
ter, the equivalent speed in km/h will be shown
in the digital speedometer.

ECO drive mode
The Eco drive mode optimizes the vehicle's driv- ing characteristics for more fuel-efficient andeco-friendly driving.
Use this mode to save fuel and promote eco- friendly driving. When ECO mode is activated, the following cha- racteristics are modified:
• The automatic transmission's shifting points.
• Engine control and accelerator pedalresponse.
• Eco Coast functionality is activated andengine braking is disabled when the acceler-ator pedal is released at speeds between65 and 140 km/h (40 and 87 mph).
• Some of the climate system settings will bereduced or switched off.
• Information will be shown in the ECO gaugein the instrument panel to help promotemore eco-friendly and economical driving.
Coast function Eco CoastEco Coast essentially deactivates engine braking,allowing the vehicle's kinetic energy to be used to roll greater distances. When the driver releases the accelerator pedal, the transmission is auto- matically disengaged from the engine. Enginespeed is reduced to idling speed to reduce fuelconsumption.

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.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driving longdistances.
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 optimally
• all lights are working
‒
adjust the headlight
height if the vehicle is carrying a heavy load
• tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy 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 make sure it can bedriven safely.
Before the cold season arrives:
• Make sure the engine coolant contains 50% antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
• Keep the fuel tank well filled to prevent con-densation from forming.
• Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.
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 places greaterdemands on the start battery and reduces itscapacity.
• Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.

WHEELS AND TIRES

Tires
The function of the tires is to carry loads, provide traction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv- ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs. Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, werecommend snow tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type (radial) andpreferably from the same manufacturer, on all four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.
Recommended tiresOn delivery, the car is equipped with Volvo origi- nal tires that have the VOL
1
marking on the side
of the tires. These tires have been designed spe- cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.
New tires
Tires are perishable goods. After a few years, they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is
