Towing a trailer
NOTE
When parking the vehicle with a trailer on a hill, apply the parking brake before putting the gear selector in Park
( P ) or in reverse on models with a manual transmission. Always follow the trailer manufacturer's recommendations
for wheel chocking.
If you use the manual (Geartronic) shift positions while towing a trailer, or if the vehicle is equipped with a
manual transmission, make sure the gear you select does not put too much strain on the engine (using too high a
gear).
The drawbar assembly/trailer hitch may be rated for trailers heavier than the vehicle is designed to tow. Please
adhere to Volvo's recommended trailer weights.
Avoid driving with a trailer on inclines exceeding 15%.

BLIS has an integrated function that alerts the driver if a fault should occur with the system. For example, if one or
both of the system's cameras are obscured, a message (see the table on page 162
) will appear in the information
display in the instrument panel. If this occurs, clean the camera lenses. If necessary, the system can be temporarily
switched off (for instructions, see page 162
).
160 06 Starting and driving
Blind Spot Information System (BLIS)-option
When does BLIS function
The system functions when your vehicle is moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:
The system reacts when you pass another vehicle at a speed of up to 6 mph (10 km/h) faster than that vehicle.
When you are passed by another vehicle:
The system reacts if your vehicle is passed by another vehicle at a speed of up to 43 mph (70 km/h) faster than your
vehicle.
WARNING
BLIS does not function in sharp curves.
BLIS does not function when your vehicle is backing up.
If you are towing a wide trailer, this may prevent the BLIS cameras from detecting other vehicles in adjacent
lanes.
How BLIS functions in daylight and darkness
Daylight
BLIS reacts to the shape of surrounding vehicles. The system is designed to help detect motor vehicles such as cars,
trucks, buses, motorcycles, etc.
Darkness
BLIS reacts to the headlights of surrounding vehicles. In order to be detected by BLIS, a vehicle in the blind area
must have its headlights on. This means, for example, that the system will not detect a trailer without headlights that is
being towed behind a car or truck.

The park assist system is designed to assist you when driving into parking spaces, garages, etc. It utilizes four
ultrasound sensors located in one or both bumpers to measure the distance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
Park assist is available in two versions:
Rear bumper only
Front and rear bumpers
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to be a supplementary aid when
parking the vehicle. It is not, however, intended to replace the driver's attention and judgement.
Function
The system is activated automatically when the vehicle is started. The indicator light in the button in the center console
illuminates.
The front park assist system is active from the time the engine is started until the vehicle exceeds a speed of
approximately 10 mph (15 km/h). It is also active when the vehicle is backing up.
Rear park assist is active when the engine is running and reverse gear has been selected.
Rear park assist
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The signal comes from the rear speakers.
The system must be deactivated when towing a trailer, carrying bicycles in a rear-mounted carrier, etc, which could
trigger the rear park assist system's sensors.
NOTE
Rear park assist is deactivated automatically when towing a trailer if Volvo genuine trailer wiring is used.
Front park assist
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signal comes from the audio
system's front speakers.
It may not be possible to combine auxiliary headlights and front park assist since these lights could trigger the system's
sensors.

Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before 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 Vehicle 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, trailer hitch tongue load
is also part of cargo weight.
NOTE
For trailer towing information, please refer to the section "Towing a trailer" on page 155
.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). These numbers 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.
NOTE
The location of the various labels in your vehicle can be found on page 252.
A table listing important weight limits for your vehicle can be found on page 255.
Steps for Determining Correct Load Limit
1. Locate the statement ''the combined weight of occupants and cargo should never exceed XXX pounds'' on your
vehicle's placard.
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 kilograms or XXX pounds.
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. passengers in your vehicle, the amount of available cargo and
luggage load capacity is 650 lbs. (1400-750 (5 x 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
1 to determine how this reduces the available

9. Start the vehicle's engine.
WARNING
The vehicle's engine should be running when the tire sealing system is used to avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated place, or outdoors, before using the system.
10. Start the tire sealing system's compressor by pressing the on/off switch to position I .
WARNING
Never stand next to the tire being inflated when the compressor is in operation.
If cracks, bubbles, etc. form on the tire, switch off the compressor immediately.
If there is visible damage to the sidewall or the rim, the tire cannot be repaired. The vehicle should not be driven if
this occurs. Contact a towing service or Volvo On Call Roadside Assistance if applicable.
NOTE
The air pressure gauge will temporarily show an increase in pressure to approximately 88 psi (6 bar) while the
sealing compound is being pumped into the tire. The pressure should return to a normal level after approximately 30
seconds.
11. Within seven minutes, inflate the tire to between 22-44 psi (1.8-3.0 bar). Switch off the compressor briefly to get a
clear reading from the pressure gauge.
CAUTION
The compressor should not be used for more than 10 minutes at a time to avoid overheating.
WARNING
If the pressure remains below 22 psi (1.8 bar) after approximately seven minutes, turn off the compressor. In this
case, the hole is too large to be sealed and the vehicle should not be driven.
12. Switch off the compressor and disconnect the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire's inflation valve and reinstall the valve cap.
14. Immediately drive the vehicle for approximately 2 miles (3 km) at a maximum speed of 50 mph (80 km/h) to
distribute the sealing compound in the tire.
NOTE
Safely stow the tire sealing system in a convenient place as it will soon be used again to check the tire's inflation
pressure.
After use, the empty bottle of sealing compound cannot be removed from the bottle holder. Consult a Volvo
retailer to have the bottle removed and properly disposed of.
WARNING
If heavy vibrations, unsteady steering behavior, or noises should occur while driving, reduce speed and park the

NOTE
The transmission oil does not normally need to be changed during the service life of the vehicle. However, it may be
necessary to replace the oil if the vehicle is often driven in areas of sustained temperature extremes (hot or cold), when
towing a trailer over long distances, for prolonged driving in mountainous areas, or if the vehicle is often driven short
distances in temperatures under 40°F (5°C).

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, or ACEA A1/B1. Lower quality oils may not
offer the same fuel economy, engine performance, or engine protection.
Volume: 6.1 US qts (5.8 liters).
ProCarManuals.com

Volume between the MIN and Max marks on the dipstick: approximately 1.4 US qts (1.3 liters).
Volvo recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine protection.
Consult your Volvo retailer or a trained and qualified Volvo service technician for recommendations on premium or
synthetic oils.
Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal service intervals. This oil is only used at customer
request, at additional charge. Please consult a trained and qualified Volvo service technician.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 104° F (40° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and complying with oil quality requirements are recommended for driving
in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
