STARTING AND DRIVING
||
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 down-
grades or when a decrease in speed is antici-
pated, 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 man-
•
ual 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
deactivate or turn off Eco Coast so that engine
braking 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 to another drive mode*
•
deactivating Eco drive mode in Function
•
view.
It is possible to roll short distances even with-
out Eco Coast in order to help conserve fuel.
However, 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
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 vehicle'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 coast-
ing.
On a steep uphill gradient, the vehicle's
•
speed is reduced until the transmission
downshifts. Reduced acceleration is then
initiated in order to reach the set speed.
On a downhill gradient in which the vehi-
•
cle 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.
