STARTING AND DRIVING
* Option/accessory.475
Checking trailer lights
When connecting a trailer, make sure that all of
the lights on the trailer are functioning before
starting to drive.
Trailer turn signals and brake lightsIf one or more of the turn signals or brake lights
on the trailer is not working, a symbol and mes-
sage will be displayed in the instrument panel.
The other lights on the trailer must be checked
manually by the driver before the vehicle is driven. Symbol

tion If any of the trailer's turn signal lights is not work-
ing, the turn signal symbol in the instrument
panel will also flash more quickly than normal.
Trailer rear fog lightWhen a trailer is connected, the vehicle's rear fog
light may not illuminate and rear fog light func-
tionality is instead transferred to the trailer. If this
is the case, check to see if the trailer is equipped
with a rear fog light before activating the vehicle's fog lights when driving with a trailer to help
ensure safe operation.
Checking trailer lights*
Automatic check
When the trailer has been connected to the vehi-
cle's electrical system, its lights can be checked
by automatically activating them. This function
helps the driver check that the trailer's lights are

WHEELS AND TIRES
578Determining the vehicle's permitted
weight
Properly loading your vehicle will provide maxi-
mum return of vehicle design performance.
Weight designationsBefore loading your vehicle, familiarize yourself
with the following terms for determining your
vehicle's weight ratings, with or without a trailer,
from the vehicle's Federal/Canadian Motor Vehi-
cle Safety Standards (FMVSS/CMVSS) label, and
the vehicle's tire information placard:
Curb weight
The weight of the vehicle including a full tank of
fuel and all standard equipment. It does not
include passengers, cargo, or optional equipment.
Capacity weight
All weight added to the curb weight, including
cargo and optional equipment. When towing, tow-
bar weight is also part of cargo weight.
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 Motor
Vehicle Safety Standards (FMVSS/CMVSS) label.
The total load on each axle must never exceed its
maximum 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 weight of 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 your
vehicle.
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 equals
1400 lbs. and there will be five 150 lb. pas-
sengers in your vehicle, the amount of availa-
ble cargo and luggage load capacity is 650
lbs. (1400 - 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle. That
weight may not safely exceed the available
cargo and luggage load capacity calculated
in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your
vehicle. Consult this manual to determine
how 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 weight
rating limits can cause tire overheating
resulting in permanent deformation or
catastrophic failure.
• Do not use replacement tires with lower
load carrying capacities than the tires that
were original equipment on the vehicle
because this will lower the vehicle's GVW
rating. Use only tires with the correct load
carrying capacity. Consult your Volvo
retailer for information.

LOADING, STORAGE AND PASSENGER COMPARTMENT
* Option/accessory.587
WARNINGIn a head-on collision at a speed of 50 km/h
(30 mph), an unsecured object weighing 20
kg (44 pounds) can reach a projectile weight
equivalent to 1000 kg (2200 pounds).
WARNING
If objects are loaded higher than the upper
edge of the side windows, leave a 10 cm (4
in.) space between the objects and the win-
dow. Objects placed closer to this could
impede the function of the inflatable curtain
concealed inside the headlining.
WARNING
Always secure the load. Otherwise, it may shift
during heavy braking and injure people in the
vehicle.
Cover sharp edges and sharp corners with
something soft.
Turn off the engine and apply the parking
brake when loading/unloading long objects.
Otherwise, it is possible for the load to reach
the gear lever or gear selector and move it to
a drive position – which could cause the vehi-
cle to begin rolling.
Extra cargo space
The rear seat backrests can be folded down to
increase cargo compartment space and simplify
loading. If the rear seat backrests are folded down, make sure that no objects loaded into the
vehicle prevent the WHIPS system for the front
seats from functioning correctly.
Raising/lowering the rear end of the
vehicle*
The rear end of the vehicle can be lowered or
raised for easier loading or to facilitate attaching
a trailer*.
The controls for raising/lowering are located at
the rear edge of the cargo compartment's right
side panel. Controls for raising/lowering the rear end of the vehicle.
The controls consist of two buttons ‒ one button
for lowering and one button for raising the rear
end. Press and hold the relevant button until the
desired height is reached.
The rear end of the vehicle cannot be raised
higher than its normal height. The rear end will return to the normal height
when the vehicle begins driving.
NOTE It is not possible to adjust the height of the
vehicle's rear when one or more of the doors
or the hood is open. This does not apply to
the tailgate.
WARNING
Make sure that no people, animals or objects
are found under the vehicle when it is low-
ered. This could endanger life and cause
damage to the vehicle or objects.

CAUTION•
The maximum trailer weights listed are
only 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 impaired
because of the reduced air density, so
the maximum trailer weight has to be
reduced accordingly. The weight of the
car and trailer must be reduced by 10%
for every further 3280 ft (1,000 m) (or
part thereof).
