ECO drive mode

The Eco drive mode optimizes the vehicle's driv-
ing characteristics for more fuel-efficient and
eco-friendly driving.

Use this mode to save fuel and promote eco-
friendly driving.

When ECO mode is activated, the following cha-
racteristics are modified:

•

The automatic transmission's shifting points.

•

Engine control and accelerator pedal
response.

•

Eco Coast functionality is activated and
engine braking is disabled when the acceler-
ator pedal is released at speeds between
65 and 140 km/h (40 and 87 mph).

•

Some of the climate system settings will be
reduced or switched off.

•

Information will be shown in the ECO gauge
in the instrument panel to help promote
more eco-friendly and economical driving.

Coast function Eco Coast

Eco Coast essentially deactivates engine braking,
allowing the vehicle's kinetic energy to be used
to roll greater distances. When the driver releases
the accelerator pedal, the transmission is auto-
matically disengaged from the engine. Engine
speed is reduced to idling speed to reduce fuel
consumption.

STARTING AND DRIVING

* Option/accessory.

436

This function is most effective in driving situa-
tions where the vehicle can roll freely for a long
distance, e.g. on roads with slight downgrades or
when a decrease in speed is anticipated, such as
when approaching an area with a lower speed
limit.

Activating Eco Coast

The function is activated when the accelerator
pedal is fully released and the following condi-
tions are met:

•

Eco drive mode is activated.

•

The gear selector is in D.

•

The vehicle's speed is approximately
65-140 km/h (40-87 mph).

•

The gradient of the downgrade is less than
approximately 6%.

COASTING will be displayed in the instrument
panel when Eco Coast is being used.

Limitations

Eco Coast is not available if:

•

The engine and/or transmission are not at
normal working temperatures.

•

The gear selector is moved from D to manual
shifting mode.

•

The vehicle's speed is not within the
65-140 km/h (40-87 mph) range.

•

The gradient of the downgrade is more than
approximately 6%.

•

The steering wheel paddles* are being used
for manual shifting.

Deactivating and turning off Eco Coast

In certain situations, it may be advisable to deac-
tivate or turn off Eco Coast so that engine brak-
ing can be used. These situations might include
driving down steep hills or before passing
another vehicle to help ensure this can be done
as safely as possible.

Deactivate Eco Coast by:

•

Pressing the accelerator or brake pedal.

•

Moving the gear selector to manual mode.

•

Using the steering wheel paddles* to shift.

Turn off Eco Coast by:

•

Switching drive mode* or switching off drive
mode Eco in Function view.

It is possible to roll short distances even without
Eco Coast in order to help conserve fuel. How-
ever, for the best fuel economy, Eco Coast should
be activated and used to roll longer distances.

Cruise control Eco Cruise

When cruise control is activated in the Eco drive
mode, the vehicle's acceleration and deceleration
will be slower than in other drive modes to help
further conserve fuel. Because of this, the vehi-
cle's actual speed may be slightly above or below
the set speed.

•

On a level road, the vehicle's actual speed
may differ from the set speed when cruise
control is active and the vehicle is coasting.

•

On a steep uphill gradient, the vehicle's
speed is reduced until the transmission
downshifts. Reduced acceleration is then ini-
tiated in order to reach the set speed.

•

On a downhill gradient in which the vehicle is
coasting, the vehicle's actual speed may be
slightly above or below the set speed. The
function uses engine braking to keep the set
speed. If necessary, the normal brakes are
also applied.

STARTING AND DRIVING

* Option/accessory.

437

ECO gauge in the instrument panel

Eco gauge in 12" instrument panel*.

Eco gauge in 8" instrument panel.

The ECO gauge indicates how economical cur-
rent driving is:

•

A low reading in the green area of the gauge
indicates economical driving.

•

A high reading is shown when driving is not
economical, e.g. heavy braking or rapid accel-
eration.

The ECO gauge also has an indicator showing
how a reference driver would drive in the same
driving situation. This is shown by the short
pointer in the gauge.

ECO Climate

In Eco mode, ECO climate is automatically acti-
vated in the passenger compartment to help
reduce energy consumption.

When the ECO function is activated, settings
for certain climate system and electricity con-
suming functions are reduced. Some of these
settings can be reset manually, but full func-
tionality will only be restored by switching off
the ECO function or adapting the

Individual

drive mode to full climate system functionality.

If condensation forms on the windows, tap the
max defroster button, which will function normally.

Start/Stop function

Start/Stop is a function that temporarily switches
off the engine when the vehicle has stopped,
e.g. at a traffic light or in heavy traffic, and then
starts it again automatically when the brake
pedal is released.

The Start/Stop function reduces fuel consump-
tion, which helps to reduce exhaust emissions.

The system makes it possible to drive more eco-
nomically and climate-smart by letting the engine
auto-stop when appropriate.

Low Speed Control

The low-speed function, Low Speed Control
(LSC), facilitates and improves control and trac-
tion on rough roads and slippery surfaces, e.g.
when towing a trailer on grass or up boat ramps.

In vehicles equipped with drive mode control*,
the function is included in the Off Road drive
mode.

Low Speed Control is designed for driving on
rough roads and when towing trailers at low
speeds, up to approximately 40 km/h (25 mph).

When driving at low speeds, LSC prioritizes low
gears and all-wheel drive to help avoid wheel spin
and improve traction on all wheels. The accelera-
tor pedal will be less responsive to improve trac-
tion and speed control at low speeds.

The function is activated together with Hill
Descent Control (HDC), which makes it possible
to control speed going down steep hills using the
accelerator pedal and reduces the need to use
the brake pedal. The system makes it possible to
maintain a low and uniform speed when driving
down steep hills.

When LSC with HDC is activated, the feel of
the accelerator pedal and engine response
will change.

This drive mode is not designed to be used
for normal street driving.

Activating and deactivating Low Speed Con-
trol using the function button (p. 445)

The function is deactivated when driving at
high speeds and must be reactivated at lower
speeds if so desired.

Hill Descent Control

The function for assisting when driving downhill,
Hill Descent Control (HDC), is a low-speed
function with increased engine braking. The
function makes it possible to increase or
decrease the vehicle's speed on steep downhill
gradients by only using the accelerator pedal,
without applying the brakes.

In vehicles equipped with drive mode control*,
the function is included in the Off Road drive
mode.

HDC is designed for driving on rough roads at
low speeds and downhill gradients with slippery
or otherwise difficult road surfaces. The driver
does not need to use the brake pedal but can
instead focus on steering.

WARNING

HDC is only intended to be a supplementary

braking aid and it does not function in all sit-

uations.
The driver is always ultimately responsible for

operating the vehicle in a safe manner.

Function

Hill Descent Control allows the vehicle to move
forward or backward at very low speeds assisted
by the brake system. The driver can increase the
speed by pressing the accelerator pedal. When
the accelerator pedal is released, the vehicle will

return to very low speed regardless of how steep
the hill is and without the brakes needing to be
applied. The brake lights will illuminate when the
function is activated.

The driver can brake to stop or slow the vehicle
at any time by depressing the brake pedal.

HDC is activated along with Low Speed Control
(LSC), which facilitates and improves traction and
control on rough and slippery surfaces. The sys-
tem is intended to be used at low speeds, up to
approximately 40 km/h (25 mph).

To keep in mind when using HDC

•

If the function is switched off while driving on
a steep downhill gradient, braking effect will
be gradually reduced.

•

HDC can be used in gear positions D and R,
and in manual gears 1 or 2.

•

It is not possible to manually shift to third
gear or higher when HDC is active.

When LSC with HDC is activated, the feel of
the accelerator pedal and engine response
will change.

This drive mode is not designed to be used
for normal street driving.

Economical driving

Drive economically and more environmentally
conscious by thinking ahead, avoiding rapid
starts and stops and adapting driving style and
speed to the current traffic conditions.

Observe the following rules:

•

For lower fuel consumption, activate Eco
drive mode.

•

Use the Eco Coast function in drive mode
Eco - engine braking is deactivated, allowing
the vehicle's kinetic energy to be used to roll
greater distances.

•

Use gear D as often as possible and avoid
using the kick-down function.

•

For manual gear shifting, use the highest
possible gear for the current traffic situation
and road conditions - fuel consumption is
reduced at lower engine speeds (rpm). Use
the gear indicator

•

Maintain a steady speed and a generous fol-
lowing distance to traffic ahead to minimize
braking.

•

Fuel consumption is increased at high
speeds - air resistance increases with speed.

•

The trip computer's current fuel consumption
indicator can help promote more fuel-effi-
cient driving.

•

Do not warm up the engine by idling. It is
better to begin driving normally immediately
after starting the engine. A cold engine uses
more fuel than a warm engine.

•

Whenever possible, avoid using the vehicle to
drive short distances. The engine does not
have time to reach a normal operating tem-
perature and this leads to increased fuel
consumption.

•

Use engine braking to brake the vehicle,
when this is safe for other road users.

•

Maintain the correct pressure in the tires and
check pressure regularly.

•

The type of tires used could affect fuel con-
sumption - consult a retailer for advice on
suitable tires.

•

Remove unnecessary items from the vehicle
- the heavier the load, the higher the fuel
consumption.

•

Roof loads increase air resistance and
increase fuel consumption. Remove roof
boxes, ski racks, etc. that are not in use.

•

Avoid driving with the windows open.

Certain markets only.

STARTING AND DRIVING

448

WARNING

Never turn off the engine while the vehicle is

moving, e.g. when driving downhill. This deac-

tivates certain important systems such as

power steering and brakes.

Other factors that decrease fuel
consumption

•

Dirty air cleaner.

•

Dirty engine oil and clogged oil filter.

•

Incorrect front-end alignment.

•

Incorrect wheel alignment.

Some of the above items and others are checked
as part of Volvo's standard maintenance sched-
ule.

Check that:

•

the engine is running properly and that fuel
consumption is normal

•

there are no leaks (fuel, oil or other fluid)

•

the brake pedal is functioning optimally

•

all lights are working

‒ adjust the headlight

height if the vehicle is carrying a heavy load

Winter driving

It is important to check the vehicle before driving
in cold/snowy conditions to make sure it can be
driven safely.

Before the cold season arrives:

•

Make sure the engine coolant contains 50%
antifreeze. This mixture helps protect the
engine from frost erosion down to
approx. -35 °C (-31 °F). Do not mix different
types of antifreeze as this could pose a
health risk.

•

Keep the fuel tank well filled to prevent con-
densation from forming.

•

Check the viscosity of the engine oil. Oil with
low viscosity (thinner oil) improves cold-
weather starting and reduces fuel consump-
tion when driving with a cold engine.

CAUTION

Low-viscosity oil should not be used with hard
driving or in hot weather.

•

Check the condition and charge level of the
start battery. Cold weather places greater
demands on the start battery and reduces its
capacity.

•

Use washer fluid containing antifreeze to
help prevent ice from forming in the washer
fluid reservoir.

Slippery driving conditions

For optimal traction and roadholding, Volvo rec-
ommends using snow tires on all wheels when-
ever there is a risk of snow or ice on the road.
