Starting and driving -> Towbar for Your Volvo XC40 SUV 2020

The car can be equipped with a towbar that

makes it possible to tow e.g. a trailer behind

the car.

There may be different towbar variants availa-

ble for the car. Contact a Volvo dealer for more

information.

If the starter battery has been discharged

so much that the car has no normal electri-

cal functions and the engine is then jump-

started with an external battery or a battery

charger, the Start/stop function may con-

tinue to be activated. If the Start/stop

function then auto-stops the engine shortly

afterwards, there is a great risk that engine

auto-start will fail due to insufficient bat-

tery capacity, because the battery has not

had the time to recharge.

When the engine is switched off, the con-

stant battery voltage to the trailer connec-

tor can be switched off automatically so as

not to drain the starter battery.

If the car has been jump-started, or if there

is insufficient time to charge the battery

with a battery charger, the Start/stop func-

tion is temporarily deactivated until the

battery has been recharged by the car. In

an outside temperature of approx. +15 °C

(approx. 60 °F), the battery needs to be

charged for at least 1 hour by the car. In a

lower outside temperature, the charging

time may increase to 3–4 hours. The rec-

ommendation is to charge the battery

using an external battery charger.

The towball needs regular cleaning and

lubrication with grease in order to prevent

wear.

Extendable and retractable towbar *

When a hitch with a vibration damper is

used, the towball must not be lubricated.

This also applies when fitting a bicycle rack

that is clamped in around the towball.

Power save mode activates after a while

and the indicator lamp goes out. The sys-

tem is reactivated by closing and opening

the tailgate. This applies when retracting or

extending the towbar.

If the car detects a connected trailer elec-

trically, the indicator lamp stops illuminat-

ing with a constant glow.

Move the towbar to its end position,

where it is secured and locked in place -

the indicator lamp illuminates with a con-

stant orange glow.

Lock the towbar by moving it back to its

retracted position, where it is locked.

Retracting the towbar

> The indicator lamp will now illuminate

with a constant glow if the towbar is

correctly retracted.

Make sure that there is no plug or adapter

in the electrical socket when retracting the

towbar.

> The towbar is ready for use.

The towbar must finish the extension pro-

cedure before it can then be moved to

locked position. This procedure may take

several seconds. If the towbar is not fixed

in locked position, wait a few seconds and

try again.

STARTING AND DRIVING

Follow the regulations in force for the per-

mitted speeds and weights.

Driving with a trailer

•

When driving with a trailer, there are a num-

ber of points that are important to think about

regarding the towbar, the trailer and how the

load is positioned in the trailer.

Payload depends on the car's kerb weight. The

total of the weight of the passengers and all

accessories, e.g. towbar, reduces the car's

payload by a corresponding weight.

When the engine is switched off, the con-

stant battery voltage to the trailer connec-

tor can be switched off automatically so as

not to drain the starter battery.

Maintain a low speed when driving with a

trailer up long, steep ascents.

The maximum indicated trailer weight only

applies to heights up to 1000 metres

above sea level (3280 ft). At higher eleva-

tions, the engine output and the vehicle's

climbing ability are reduced due to the

reduced air density, and the maximum

trailer load must therefore be reduced. The

weight of the car and trailer must be

decreased by 10% for each additional

1000 m (3280 ft) or part thereof.

Trailer weights

WARNING

The car is supplied with the necessary equip-

ment for towing a trailer.

Follow the stated recommendations for

trailer weights. Otherwise, the car and

trailer may be difficult to control in the

event of sudden movement and braking.

The car's towbar must be of an approved

type.

•

Distribute the load on the trailer so that

the weight on the towbar complies with

the specified maximum towball load. Tow-

ball load is calculated as part of the car's

payload.

•

Avoid driving with a trailer on inclines of

more than 12%.

•

The stated maximum permitted trailer

weights are those permitted by Volvo.

National vehicle regulations can further

limit trailer weights and speeds. Towbars

can be certified for higher towing weights

than the car can actually tow.

Trailer stability assist * (p. 454)

Extreme weather conditions, driving with a

trailer or driving at high altitudes, in combi-

nation with poorer fuel quality than recom-

mended, are factors that considerably

increase the car's fuel consumption.

Increase the tyre pressure to the recom-

mended pressure for a full load.

•

The engine is loaded more heavily than

usual when driving with a trailer.

Do not tow a heavy trailer when the car is

brand new. Wait until it has been driven at

least 1000 km (620 miles).

Level control*

Trailer connector

The car's system for level control endeavours

to maintain a constant height regardless of

load (up to the maximum permissible weight).

When the car is stationary the rear of the car

lowers slightly, which is normal.

An adapter is required if the car's towbar has a

13 pin connector and the trailer has a 7 pin

connector. Use an adapter approved by Volvo.

Make sure the cable does not drag on the

ground.

The brakes are loaded much more than

usual on long and steep downhill slopes.

Downshift to a lower gear when shifting

manually and adjust your speed.

Reasons for snaking

Towing capacity and towball load

(p. 634)

The snaking phenomenon can occur with any

car/trailer combination. Snaking normally

occurs at high speeds. However, there is a risk

of it occurring at lower speeds if the trailer is

overloaded or the load is improperly distrib-

uted, e.g. too far back.

The following applies for cars with automatic

gearbox:

Overheating in the engine and drive sys-

tem (p. 446)

The automatic gearbox adapts the gears

depending on load and engine speed.

(p. 639)

Steep inclines

Extendable and retractable towbar *

Do not lock the automatic gearbox in a higher

gear than the engine "can cope with" - it is not

always a good idea to drive at a high gear with

low engine speed.

In order for snaking to occur, there must be a

triggering factor, e.g.:

powerful side wind.

surface or in a pothole.

2. Activate the parking brake.

3. Select gear position P.

4. Release the brake pedal.

Sweeping steering wheel movements.

If snaking has started, it could be difficult or

even impossible to suppress. This makes the

car/trailer combination difficult to control and

there is a risk that you could, for example, end

up in the wrong lane or leave the carriageway.

serves to stabilise the car/trailer combination.

This is often enough to help the driver regain

control of the car.

When Trailer Stability Assist

(TSA) is operating, the ESC

symbol flashes in the driver

display.

Checking trailer lamps

When connecting a trailer - check that all the

trailer lamps work before departure.

If snaking is not eliminated the first time that

trailer stability assist intervenes, the car/trailer

combination is braked with all wheels and

engine power is reduced. Once snaking has

been gradually suppressed and the car/trailer

combination is stable once again, the system

stops regulating and the driver once again has

full control of the car.

Direction indicators and brake lights

on the trailer

If one or more of the trailer's direction indica-

tors or brake light bulbs is broken, the driver

display shows a symbol and a message. Other

lights on the trailer must be checked manually

by the driver before setting off.

Trailer stability assist may fail to intervene if

the driver uses severe steering wheel move-

such a situation the system cannot determine

whether it is the trailer or the driver causing

the snaking.

If any lamp for the trailer's direction indicators

is broken, the driver display symbol for direc-

tion indicators will also flash more quickly than

normal.

Recommendations for loading

bicycles on the bicycle rack

The larger the distance between the load's

centre of gravity and the towball, the greater

the load on the towbar.

Some gear lever variants make it impossi-

ble to shift out of P unless the engine is

running. Contact an authorised Volvo

workshop for assistance when towing, or

summon professional help for recovery.
