Starting and driving -> Refueling for Your Volvo Xc90 SUV 2020

An over-full tank may overflow in hot

weather.

Avoid spilling gasoline during refueling. In

addition to causing damage to the environ-

ment, gasolines containing alcohol can

cause damage to painted surfaces, which

may not be covered under the New Vehicle

areas require the use of "oxygenated" fuel.

Fuel

Volvo recommends the use of detergent gas-

oline to control engine deposits.

Volvo permits the use of the following "oxy-

genated" fuels. However, the specified octane

ratings must still be met.

Deposit control gasoline (gasoline

with detergent additives)

Alcohol - Ethanol

Detergent gasoline is effective in keeping

injectors and intake valves clean. Consistent

use of deposit control gasolines will help

ensure good driveability and fuel economy. If

you are not sure whether the gasoline contains

deposit control additives, check with the serv-

ice station operator.

Fuels containing up to 10% ethanol by volume

may be used. Ethanol may also be referred to

as Ethyl alcohol, or "Gasohol".

Some U.S. and Canadian gasolines contain

an octane enhancing additive called

methyl-cyclopentadienyl manganese tricar-

bonyl (MMT). If such fuels are used, your

Emission Control System performance

may be affected, and the Check Engine

Light (malfunction indicator light) located

on your instrument panel may light. If this

occurs, please return your vehicle to a

trained and qualified Volvo service techni-

cian for service.

Ethers - MTBE/ETBE: Fuels containing up to

22% MTBE/ETBE by volume may be used.

Methanol

Do not use gasolines containing methanol

(methyl alcohol, wood alcohol). This practice

can result in vehicle performance deterioration

and can damage critical parts in the fuel sys-

tem. Such damage may not be covered under

the New Vehicle Limited Warranty.

Emission controls (p. 433)

Volvo recommends not using external fuel

injector cleaning systems, e.g. do not add

detergent additives to gasoline before or

after refueling.

pumps delivering unleaded gasoline are

labeled "UNLEADED". Only the nozzles of

these pumps will fit in your vehicle's fuel filler

inlet. It is unlawful to dispense leaded fuel into

a vehicle labeled "unleaded gasoline only".

Octane rating

Volvo requires premium fuel (91 octane¹⁸or

higher) for all T5, T6 and T8 engines, and rec-

ommends AKI 93 for optimal performance

and fuel economy. See decal examples in

When switching to higher octane fuel or

changing gasoline brands, it may be neces-

sary to fill the tank more than once before a

difference in engine operation is noticea-

ble.

Do not use gasoline that contains lead or man-

ganese as a knock inhibitor, and do not use

lead additives. Besides damaging the exhaust

emission control systems on your vehicle, lead

has been strongly linked to certain forms of

cancer.

.

TOP TIER Detergent Gasoline

Volvo endorses the use of "TOP TIER Deter-

gent Gasoline" where available to help main-

tain engine performance and reliability. TOP

TIER Detergent Gasoline meets a new stand-

ard jointly established by leading automotive

manufactures to meet the needs of today's

advanced engines. Qualifying gasoline retail-

ers (stations) will, in most cases, identify their

gasoline as having met the "TOP TIER Deter-

gent Gasoline" standards.

Many fuels contain benzene as a solvent.

Unburned benzene has been strongly linked to

certain forms of cancer. If you live in an area

where you must fill your own gas tank, take

precautions. These may include:

may be a good idea to switch to a higher-

octane fuel (AKI¹⁸91 or higher) or to switch to

another brand of gasoline in order to fully uti-

lize the vehicle's engine capacity and optimize

traction.

Use of Additives

Emission controls

Three-way catalytic converter

With the exception of gas line antifreeze dur-

ing winter months, do not add solvents, thick-

eners, or other store-bought additives to your

vehicle's fuel, cooling, or lubricating systems.

Overuse may damage your engine, and some

of these additives contain organically volatile

chemicals. Do not needlessly expose yourself

to these chemicals.

Keep your engine properly tuned. Certain

engine malfunctions, particularly involving

the electrical, fuel or distributor ignition

systems, may cause unusually high three-

way catalytic converter temperatures. Do

not continue to operate your vehicle if you

detect engine misfire, noticeable loss of

power or other unusual operating condi-

tions, such as engine overheating or back-

firing. A properly tuned engine will help

avoid malfunctions that could damage the

three-way catalytic converter.

WARNING

Never carry a cell phone that is switched

on while refueling your vehicle. If the

phone rings, this may cause a spark that

could ignite gasoline fumes, resulting in fire

and injury.

Do not park your vehicle over combustible

materials, such as grass or leaves, which

can come into contact with the hot

exhaust system and cause such materials

to ignite under certain wind and weather

conditions.

•

WARNING

Carbon monoxide is a poisonous, colorless,

and odorless gas. It is present in all exhaust

gases. If you ever smell exhaust fumes

inside the vehicle, make sure the passenger

compartment is ventilated, and immedi-

ately return the vehicle to a trained and

qualified Volvo service technician for cor-

rection.

Excessive starter cranking (in excess of

one minute), or an intermittently firing or

flooded engine can cause three-way cata-

lytic converter or exhaust system over-

heating.

WARNING

Batteries generate hydrogen gas,

which is flammable and explosive.

If the starter battery has been discharged

to the extent that the vehicle does not have

normal electrical functions and the engine

must then be jump-started with an external

battery or a battery charger, the Start/Stop

function may remain activated. If the Start/

Stop function shortly thereafter auto-stops

the engine, there is a huge risk that auto-

start of the engine will fail due to insuffi-

cient battery capacity since the battery had

not had time to recharge.

•

Do not connect the jumper cable to

any part of the fuel system or to any

moving parts. Avoid touching hot

manifolds.

Battery fluid contains sulfuric acid. Do

not allow battery fluid to contact eyes,

skin, fabrics or painted surfaces.

•

If contact occurs, flush the affected

area immediately with water. Obtain

medical help immediately if eyes are

affected.

If the vehicle has been jump-started or if

there has not been enough time for the

battery to be charged with a battery

charger, the Start/Stop function should be

temporarily deactivated until the battery

has been recharged by the vehicle. At an

ambient temperature of about +15°C

(about 60°F), the battery must be charged

by the vehicle for at least one hour. At

lower ambient temperatures, the charging

time can increase to 3-4 hours. It is advisa-

ble to charge the battery with an external

battery charger.

Never expose the battery to open flame

or electric spark. Do not smoke near

the battery. Failure to follow the

instructions for jump starting can lead

to injury.

STARTING AND DRIVING

Driving with a trailer

WARNING

There are a number of things to consider

when towing a trailer, such as the towbar, the

trailer and how the load is distributed in the

trailer.

Load-carrying capacity is determined by the

vehicle's curb weight. The total weight of all

passengers and any installed accessories, e.g.

towbar, reduces the vehicle's load-carrying

capacity by the corresponding amount.

Damage may occur on the towbar if it is

not used correctly or if incorrect or faulty

accessories are used, such as:

Overloading of accessory.

•

Use of incorrect or faulty accessory.

Accessory used for an incorrect pur-

pose.

Use of weight-distributing towing sys-

tem.

||

Follow applicable regulations regarding

permitted speed and weight.

•

Bumper-attached trailer hitches must

not be used on Volvos, nor should

safety chains be attached to the

bumper.

Extreme weather conditions, towing a

trailer, high altitude and lower fuel grade

than recommended are factors that can

significantly increase the vehicle's fuel con-

sumption.

•

Drive slowly when towing a trailer up a

long and steep incline.

The maximum trailer weights given only

apply to altitudes up to 1000 meters

(3280 feet) above sea level. At higher alti-

tudes, engine power (and thus the vehi-

cle's climbing ability) is decreased due to

the reduced air density, and the maximum

trailer weight must therefore be reduced.

The weight of the vehicle and trailer must

be decreased by 10% for each additional

1000 m (3280 feet) or part thereof.

Trailer hitches attaching to the vehicle

rear axle must not be used.

Please adhere to the recommendations

provided for trailer weight. If the recom-

mendations are not followed, the vehicle

and trailer may be difficult to control during

evasive maneuvers and braking.

Avoid driving with a trailer on inclines of

more than 12%.

•

When towing a trailer, the trailer's

safety chains or wire must be correctly

fastened to the attachment points pro-

vided in the trailer hitch on the vehicle.

The safety chain or wire must never be

Trailer Stability Assist may not intervene if the

driver tries to compensate for the swaying

motion by moving the steering wheel rapidly,

because the system will then not be able to

determine if it is the trailer or the driver caus-

ing the swaying.

If any of the trailer's turn signal lights is not

working, the turn signal symbol in the instru-

ment panel will also flash more quickly than

normal.

Trailer rear fog light

Towing using a towline

This section refers to one vehicle being towed

behind another using a towline.

Before towing another vehicle, check applica-

ble speed limit regulations.

When a trailer is connected, the vehicle's rear

fog light may not illuminate and rear fog light

functionality 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.

> All of the lights on the trailer will begin

flashing, and then illuminate separately

one at a time.

4. Visually check that all of the trailer's lights

are functioning correctly.
