Loading specifications Properly loading your vehicle will provide maxi- mum return of vehicle design performance.
Weight designations
Before loading your vehicle, familiarize yourself with the following terms for determining yourvehicle's weight ratings, with or without a trailer,from the vehicle's Federal/Canadian Motor Vehi-cle Safety Standards (FMVSS/CMVSS) label, andthe vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
Permissible axle weight
The maximum allowable weight that can be car- ried by a single axle (front or rear). These num-bers are shown on the Federal/Canadian MotorVehicle Safety Standards (FMVSS/CMVSS) label.The total load on each axle must never exceed itsmaximum permissible weight.
Gross vehicle weight (GVW)
The vehicle's curb weight + cargo + passengers.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined weightof occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle's plac-ard.
2. Determine the combined weight of the driver and passengers that will be riding in yourvehicle.
3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.
4. The resulting figure equals the available amount of cargo and luggage load capacity.For example, if the "XXX" amount equals1400 lbs. and there will be five 150 lb. pas-sengers in your vehicle, the amount of availa-ble cargo and luggage load capacity is650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. Thatweight may not safely exceed the availablecargo and luggage load capacity calculatedin Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to yourvehicle. Consult this manual to determinehow this reduces the available cargo and lug-gage load capacity of your vehicle.
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.

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 about this symbol, 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.
