STARTING AND DRIVING
364
Start/Stop
Start/Stop is a function that temporarily switches
off the engine when the vehicle is not moving,
for instance in heavy traffic or at a traffic light, to
help reduce fuel consumption. The engine starts
again automatically when the brake pedal is
released.
Start/Stop is one of several fuel-conserving fea-
tures that also help reduce emissions.
This feature helps make it possible to drive more
economically by allowing the engine to auto-stop
in certain situations.

Using the Start/Stop function
Start/Stop is a function that temporarily switches
off the engine when the vehicle is not moving,
for instance in heavy traffic or at a traffic light, to
help reduce fuel consumption. The engine starts
again automatically when the brake pedal is
released.
Start/Stop is available when the engine has been
started. The instrument panel will indicate if the
function is available/unavailable/active.
All of the vehicle's normal systems such as light-
ing, infotainment, etc., function normally when the
engine has auto-stopped. However, certain func-
tions, such as climate system blower speed or
very high infotainment system volume, will be
temporarily reduced.
Auto-stop
The following conditions must be met for the
engine to auto-stop:
•
Stop the vehicle by applying the brakes and
keep the brake pedal depressed. The engine
will auto-stop. If the COMFORT
8
or ECO driv-
ing modes are activated, the engine can
auto-stop before the vehicle has come to a
standstill.
If the Adaptive cruise or Pilot Assist functions
are activated, the engine will auto-stop after
approx. 3 seconds. See also the article "Condi-
tions for Start/Stop."
Auto-start
The following conditions must be met for the
engine to auto-start:
•
Release the brake pedal; the engine will
automatically restart. When starting on an
uphill incline, the Hill Start Assist (HSA)
function will be activated to help prevent the
vehicle from rolling backward.
•
When the brake system's Auto Hold function
is activated, the engine will not auto-start
until the accelerator pedal is pressed.
•
When Adaptive cruise or Pilot Assist are
activated, the engine will auto-start when the
accelerator pedal is pressed or if the
button is pressed on the left-side steering
wheel keypad.
•
Keep the brake pedal depressed but press
the accelerator pedal. The engine will auto-
start.
•
On a downhill incline, release the brake pedal
so that the vehicle begins to roll. The engine
will auto-start after a slight increase in speed.
