When shutting offIf the function is active and holding the
vehicle stationary using the normal
brakes (A symbol lit), the brake pedal
must be depressed while pressing the
button in order to deactivate Auto-hold. •
The function will remain off until it is reactiva-
ted.
• When Auto-hold is switched off, Hill Start
Assist (HSA) will remain active to help pre-
vent the vehicle from rolling backward when
starting up a hill.
Related information
•Auto-hold brakes (p. 436) Hill Start Assist
The function for assisting when starting the vehi-
cle on inclines, Hill Start Assist (HSA), helps
prevent the vehicle from rolling backward when
starting on an uphill gradient. When backing up
a hill, HSA helps prevent the vehicle from rolling
forward.
The function retains pressure from the brake
pedal in the brake system for several seconds
after the brake pedal has been released.
This temporary braking effect is released after a
few seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-hold
brake function is switched off.
Related information
• Auto-hold brakes (p. 436)
• Brakes (p. 429) Braking assist after a collision
In a collision in which the activation level is
reached for the pyrotechnic seat belt tensioners
or airbags, or if a collision with a large animal is
detected, the vehicle's brakes will be automati-
cally activated. This function is intended to help
prevent or reduce the effects of any subsequent
collision.
After a serious collision, it may no longer be pos-
sible to control and steer the vehicle. In order to
avoid or mitigate a possible further collision with
a vehicle or an object in the vehicle's path, the
brake assist system is activated automatically to
help stop the vehicle safely.
The brake lights and hazard warning flashers are
activated during braking. When the vehicle has
stopped, the hazard warning flashers will con-
tinue to flash and the parking brake will be
applied.
If braking is not appropriate, e.g. if there is a risk
of being hit by passing traffic, the driver can over-
ride the system by depressing the accelerator
pedal.
This function assumes that the brake system is
intact after a collision.
Brake assist is part of the Rear Collision Warning
and Blind Spot Information safety systems.

* Option/accessory.
468 Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
• Engine power may be temporarily limited.
• Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
• If the temperature in the engine's cooling
system becomes too high, a warning symbol
will appear in the instrument panel along with
the message Engine temperature High
temperature Stop safely. Pull over to a safe location and let the engine idle for a few
minutes to cool down.
• If the message
Engine temperature High
temperature Turn off engine or Engine
coolant Level low, turn off engine is dis- played, stop the vehicle and turn off the
engine.
• If the transmission begins to overheat, an
alternative gear shifting program will be
selected. An integrated protective function
will also be activated, the warning symbol will
illuminate and the message Transmission
warm
Reduce speed to lower
temperature or Transmission hot Stop
safely, wait for cooling will be displayed in the instrument panel. Follow the recommen-
dations given by reducing speed or stopping the vehicle safely and letting the engine idle
for a few minutes to let the transmission
cool.
• If the vehicle begins to overheat, the air con-
ditioning may be temporarily switched off.
• After a prolonged period of driving in
demanding conditions, do not turn off the
engine immediately after stopping.
NOTE It is normal for the engine's cooling fan to
operate for a short time after the engine is
switched off.

1.
Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery)
has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make sure
that the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION Connect the jump cable carefully to prevent
short circuits with other components in the
engine compartment.
5. Fold back the cover over your vehicle's posi-
tive (+) jump start terminal (2).
6.

Clamp the other end of the red jumper cable
to your vehicle's positive (+) jump start termi-
nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) ground
point (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jump
starting. 10. Start the engine of the assisting vehicle and
let it run for a few minutes at a higher idling
speed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10
minutes of charging time and then try to start
the engine again.
NOTE When the engine is started under normal
conditions, the vehicle's electrical drive motor
is prioritized – the gasoline engine remains
off. This means that the electric motor has
"started" and the vehicle is ready to be driven
once the start knob has been turned clock-
wise. Start of the electric motor is indicated
by the indicator lights on the instrument panel
going out and its preselected theme illuminat-
ing.
CAUTION
Do not touch the connections between the
cable and the vehicle during the start attempt.
Risk of sparking. 12. Remove the jumper cables in the reverse
order ‒ first the black cables and then the
red cables.
Make sure that none of the clamps of the
black jumper cables come into contact with
either vehicle's positive (+) jump start termi-
nals or either of the red jumper cable's con-
nected clamps.
WARNING PROPOSITION 65 VARNING!WARNING!
Battery posts, terminals, and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the state of California to cause
cancer and reproductive harm. Wash hands
after handling.
WARNING
•
Batteries generate hydrogen gas, which
is flammable and explosive.
• 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.

STARTING AND DRIVING
* Option/accessory.473
CAUTION•
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
• Trailer hitches attaching to the vehicle
rear axle must not be used.
• Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
• When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or wound around the towing ball.
NOTE The optional detachable trailer hitch may not
be available in all markets or on all models.
Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,
driving at high altitudes and fuel quality are
factors that significantly increase a vehicle's
fuel consumption.
Trailer weights
WARNING Please adhere to the recommendations provi-
ded for trailer weight. If the recommendations
are not followed, the vehicle and trailer may
be difficult to control during evasive maneu-
vers and braking.
NOTE
The specified maximum trailer weights are
those permitted by Volvo. National vehicle
regulations may set additional restrictions on
trailer weight and speed. The trailer hitches
may be certified for higher towing weights
than the vehicle is permitted to tow.
Self-leveling suspension*The vehicle's self-leveling system attempts to
keep the vehicle at a constant level, regardless of
load (up to the maximum permitted weight).
When the vehicle is stationary, the rear end of the
vehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-
ing when driving with a trailer. If overheating of
the engine and drive system is detected, a warn-
ing symbol will illuminate in the instrument panel
along with a message.The automatic transmission selects the optimal
gear for the current load and engine speed.
Steep inclines
Do not lock the automatic transmission into a
higher gear than what the engine can handle ‒ it
is not always preferable to drive in high gears at
low rpm.
Parking on a hill
1. Depress the brake pedal.
2. Apply the parking brake.
3. Put the gear selector in P.
4. Release the brake pedal.
Put chocks behind the wheels when the vehicle
is parked on a hill with a trailer attached.

||MAINTENANCE AND SERVICE
640
•
Wash using a sponge, car washing detergent
and plenty of lukewarm water.
• Clean the wiper blades with lukewarm soap
solution or car washing detergent.
• Dry the vehicle using a clean, soft chamois or
a squeegee. Try not to let drops of water dry
in strong sunlight. This could cause water
drying stains that may need to be polished
out.
• In areas with heavy industrial emissions,
more frequent washing of the vehicle's exte-
rior is recommended.
• Tar spots from asphalt may remain even after
washing. Use a tar remover to remove these
spots after washing the vehicle.
WARNING Always entrust engine washing to a workshop.
If the engine is hot, there is a risk of fire.
CAUTION
Dirty headlights do not work as well. Clean
them regularly, e.g. when refueling.
Do not use corrosive cleaners. Use water and
a non-abrasive sponge.
NOTE Exterior lighting such as headlights and tail-
lights may develop temporary condensation
on the inside of the lens. This is normal. All
exterior lighting is designed to resist this.
Condensation is normally vented out of the
lamp housing once the light has been lit for
some period of time.
CAUTION
•
Make sure that the panoramic roof and
sun shade are closed before washing the
vehicle.
• Never use abrasive polishing agents on
the panoramic roof.
• Never use wax on the rubber seals
around the panoramic roof.
CAUTION Remember to remove dirt from the drain
holes in the doors and sills after washing the
vehicle.
