Instrument cluster

When engine oil temperatures are low, the dis-
play --- °F (--- °C) appears in the instrument clus-
ter. The engine has reached its operating temper-
ature when the engine oil temperature is be-
tween 176 °F (80 °C) and 248 °F (120 °C) under
normal driving conditions. The engine oil temper-
ature may be higher if there is heavy engine load
and high temperatures outside. This is not a
cause for concern as long as the B or 2 indica-
tor lights do not turn on.
Boost indicator
Applies to: vehicles with boost indicator
Depending on vehicle equipment, the current en-
gine load (meaning the current boost pressure)
may be indicated by a bar in the instrument clus-
ter.
> Open the vehicle functions tab and switch to
the enhanced view > page 13.

— Driver assistance
— Traffic sign recognition and traffic light infor-
mation
Short-term memory and long-term memory
The short-term memory collects driving informa-
tion from the time the ignition is switched on un-
til it is switched off. If you continue driving within
two hours after switching the ignition off, the
new values will be included when calculating the
current trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se-
lect the time period for evaluating trip informa-
tion yourself.
Average consumption
The current consumption can be shown using a
bar graph. The average consumption stored in
the short-term memory is also displayed. If the
bar is green, your vehicle is saving energy (for ex-
ample, using recuperation).
Energy consumers
The Energy consumers view lists other equip-
ment that is currently affecting fuel consump-
tion. The display shows up to three equipment
items. The equipment using the most power is
listed first. If more than three items using power
are switched on, the equipment that is currently
using the most power is displayed. A gauge also
shows the current total consumption of all other
equipment.

Equipment that uses a lot of electricity is switch-
ed off temporarily when you start the engine. If
the engine does not start immediately, the start-
ing procedure stops automatically after a short
time. If this is the case, repeat the starting pro-
cedure after approximately 30 seconds.
Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button. The
engine will switch off.


Plug-in-hybrid drive: the electric drive system and
the combustion engine are switched off.
Applies to: vehicles with steering lock: The steer-
ing is locked when you turn off the engine with
the selector lever in the “P” position and open
the driver's door. The steering lock helps prevent
vehicle theft.
Stopping the engine in an emergency
If necessary in an emergency, the engine can also
be stopped while driving using the emergency off
function*.

> Press the [START ENGINE STOP] button twice in
a row or press and hold it one time.

Switching on and off
If you would like to switch the ignition on or off
without starting the engine, follow these steps:

> Press the [START ENGINE STOP] button without
pressing the brake pedal.

Switching the ignition off automatically
To prevent the vehicle battery from draining, the
ignition and possibly the exterior lighting may
switch off automatically.
Requirements:
— Conventional drive system: the Start/Stop sys-
tem must have stopped the engine.
— Plug-in hybrid drive: you must have driven the
vehicle. The combustion engine must not be
running.
— You must have left the vehicle for longer than
30 seconds.
— The ignition must be switched on.
Among other indicators, the system detects that
you have left the vehicle based on the following
factors:
— The driver's door has been opened.
— The driver's safety belt has been unbuckled.
— The brake pedal is not being pressed.
The ignition will also be switched off after 30 mi-
nutes or if you lock the vehicle from the outside.

ZA WARNING
—To reduce the risk of asphyxiation, never al-
low the engine to run in confined spaces.
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. You would then need to use
more force to steer and brake the vehicle.
The fact that you cannot steer and brake as [>

usual may increase the risk of accidents and
serious injuries.
— Secure the vehicle against rolling before ex-
iting the vehicle > page 108.

@) Note
— Avoid high engine speed, full throttle, and
heavy engine load if the engine has not
reached operating temperature yet. You
could damage the engine.
— If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off and there is a risk of damag-
ing the engine. For this reason, let the en-
gine run at idle for approximately two mi-
nutes before shutting it off.
@ Tips
— Brief noises are normal when starting and
stopping the vehicle and are no cause for
concern.
— For up to 10 minutes after stopping the en-
gine, the radiator fan may turn on again au-
tomatically or it may continue to run, even if
the ignition is switched off.
— It may not be possible to start the vehicle in
extremely low temperatures.
— Power will be fully available once the engine
is at operating temperature.

Driving

— Avoid adding extra weight to the vehicle if pos-
sible, for example by not leaving roof racks or
bike racks installed when they are not needed.
— Make sure the tire pressure is correct.
— Have maintenance performed regularly on the
vehicle.
— Do not let the engine run while the vehicle
parked.
— Do not drive with winter tires during the summ-
er.
— Use the Start/Stop system.
— Utilize the engine braking effect.
— Avoid driving short distances when possible.
@) Tips
The amount of noise produced by the vehicle
can increase significantly when driving with a
sporty style. Show respect to others around
you and the environment with the way you op-
erate your vehicle, especially at night.
eh Me lele 4
Your vehicle is equipped with an intelligent ener-
gy management system for distributing electrici-
ty. This significantly improves the starting ability
and increases the vehicle battery life.
@ Tips
— If you drive short distances frequently, the
vehicle battery may not charge enough
while driving. As a result, convenience func-
tions for electrical equipment may be tem-
porarily unavailable.
— The vehicle battery will gradually drain if
the vehicle is not driven for long periods of
time, or if electrical equipment is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be limited or
switched off.
