STARTING AND DRIVING
422
When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible.

PURE
This mode activates the electric motor only withas low energy consumption as possible and thelowest possible carbon dioxide emissions.
Ground clearance will be lowered to help reducewind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery issufficiently charged. If the level gets too low, thegasoline engine will start.
The gasoline engine will also start:
•If the vehicle's speed goes above approx.78 mph (125 km/h)
•If the driver wants more response than theelectric motor alone can provide
•If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that havebeen reduced in the mode, press the AUTO ordefroster buttons.
In order to return to full functionality for all of thesystems that may be affected by Pure mode,select another drive mode or adapt the climatesystem functions using the INDIVIDUAL mode.
OFF ROAD
This mode helps maximize the vehicle's capacityto 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.
This drive mode can only be activated at lowspeeds (the permissible speed range will beshown on the speedometer). At higher speeds,OFF ROAD mode will be cancelled and AWD willbe activated.
This mode is not intended for normal streetdriving.

CAUTION
OFF ROAD drive mode may not be used ifthe 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 theOFF ROAD mode was selected when the enginewas switched off, it will also restart in this mode.

AWD
This mode offers improved traction using four-wheel drive and is intended primarily for low-speed driving on slippery surfaces. However, it
also helps increase directional stability at higherspeeds.
In this mode, both the electric motor and the gas-oline engine are used continuously, which resultsin higher fuel consumption.
POWER
Power mode is intended for sportier, more activedriving.
This mode maximizes the combined effects ofthe electric motor and the gasoline engine andprovides power to all four wheels. Response topressure on the accelerator pedal is more imme-diate and the transmission shifts up at higherspeeds. Steering response is also more immedi-ate, the suspension is stiffer and lower groundclearance reduces body roll when cornering.
In this mode, both the electric motor and the gas-oline engine are used continuously, which resultsin higher fuel consumption.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUSTCONFORM 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

TREADWEAR
The treadwear grade is a comparative ratingbased 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.

TRACTION
The 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 isbased on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.

TEMPERATURE
The 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.
Snow tires and chains
The use of snow chains and/or winter tires canhelp improve traction in winter driving conditions.
Snow chains can be used on your Volvo with thefollowing restrictions:
•Snow chains should be installed on frontwheels only. Use only Volvo approved snowchains.
•If accessory, aftermarket or "custom" tiresand wheels are installed and are of a size dif-ferent than the original tires and wheels,chains in some cases CANNOT be used.Sufficient clearances between chains andbrakes, suspension and body componentsmust be maintained.
•Some strap-on type chains will interfere withbrake components and therefore CANNOTbe used.
•All Wheel Drive models: Snow chainsshould only be installed on the front wheels.
•Certain size tires may not allow the assemblyof snow chains/traction devices.
Consult your Volvo retailer for additional snowchain information.
