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.

Opening and closing the hood The hood is opened by releasing it from the pas- senger compartment and then by using the han-dle under the front edge of the hood.
Opening
With the hood completely closed, pull the control (located to the left of the brakepedal).
Turn the handle under the front edge of the hood counterclockwise to release it from thelock and lift.
Warning–hood not closed
When the hood lock has been com- pletely released, this symbol and agraphic will illuminate in the instrumentpanel and an audible signal will be
given. If the vehicle begins to roll, the audible sig-nal will be repeated several times. For additional information, see also the article "Door and seat belt reminders."
NOTE
If the warning symbol remains on or if the audible signal is given even if the hood iscompletely closed and locked, consult atrained and qualified Volvo service technician.
Closing1. Press down the hood until it begins to close due to its own weight.
2. When the handle under the front edge of the hood is in the lock, press down on the hood to close it completely.
WARNING
• Be sure the hood is completely unob- structed while it is being closed.
• Check that the hood locks properly whenclosed. It must audibly lock on both sides.
• Never drive if the hood is not completelyclosed and locked.
• While driving, if there are any indicationsthat the hood is not locked in the closedposition, stop safely as soon as possibleand close it completely.

CAUTION
•When loading the vehicle, the maximum gross vehicle weight and permissible axleweights may not be exceeded.
• The maximum trailer weights listed areonly applicable for altitudes up to 3280 ft(1,000 m) above sea level. With increas-ing altitude the engine power and there-fore the car's climbing ability are impairedbecause of the reduced air density, sothe maximum trailer weight has to bereduced accordingly. The weight of thecar and trailer must be reduced by 10%for every further 3280 ft (1,000 m) (orpart thereof).

Hybrid battery specifications
The hybrid battery is used to power the electric motor for the rear wheels when the gasolineengine is not being used.
Type:  lithium-ion
Power reserve:  9.2 kWh
NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
