Adaptive System; Safety Systems - Volvo S80 Owner's Manual

Under certain conditions, e.g. when driving in
hilly terrain and with a heavy load, especially in
warm weather, there is a risk of the engine and
cooling system overheating.
To prevent the cooling system from
overheating:
· Drive at low speeds if driving with a trailer
up a long incline.
· Switch off the air conditioning temporarily.
· Avoid letting the engine idle.
· Do not turn the engine off immediately you
stop, if the car has been driven hard.
· Remove any auxiliary lamps from in front
of the grille if driving in extremely high
temperatures.
To prevent the engine from overheating:
Do not exceed engine speeds of 4500 rpm
(diesel engine: 3500 rpm) if driving with a
trailer or caravan in hilly terrain. The oil
temperature can become too high.

Adaptive system

The gearbox is controlled by what is known as
an adaptive system. The system continually
monitors how the gearbox is behaving
senses every gear change for optimum shift
quality.

Lock-up function
The gears have a lock-up function (locked
gears), which gives better engine braking and
lower fuel consumption.

Safety systems

Cars with automatic gearbox have special safety
systems:
Keylock
To remove the ignition key, the gear selector
must be in the P position.
The key is locked in all other positions.
Park position (P)
Stationary car with engine running:
Hold your foot on the brake pedal when
moving the gear selector to another position.
Shiftlock
Park position (P)
The brake pedal must be depressed to move the
gear selector from position P to other gear
positions when the ignition key is in position I
or II.
Neutral position (N position)
The brake pedal must be depressed to move the
gear selector from position N to other gear
positions when the ignition key is in position I
or II.
When starting in cold temperatures, gear shifts
may feel harder.
This is due to the viscosity of the transmission
fluid at low temperatures.
To minimise engine emissions, the gearbox
shifts up later than normal if the engine has
been started at low temperatures.
When the engine is cold, the gearbox shifts
gears at higher revs.
This allows the catalytic converter to reach
normal operating temperature more quickly.
When the accelerator is pressed all the way to
the floor, beyond the position normally
regarded as full acceleration, a lower gear is
immediately engaged. This is known as kick-
down.
When maximum speed for this gear is reached,
or if the accelerator is released from the kick-
down position, the gearbox automatically
changes up.
Kick-down is used when maximum accelera-
tion is needed, such as for overtaking.
To prevent over-revving, the gearbox control
program has a protective downshift inhibitor.
The kick-down function cannot be used in
the manual* positions. Return to automatic
position D.
