You can call up the fo llowing info rmat ion in the
on-board computer:
- Da te
- Dr iv ing t ime from the short-te rm memory
-Average consumption from the short -term
memory
- Average speed from the short-term memory
- Distance driven from the short-term memory
- Current fuel consumption
- Short-term memory overv iew
- Long -te rm memory overv iew
The short-term memory collects drivi ng informa­
tion from the time the ignition is switched on un­
ti l it is switched off . If you continue driving with­
i n two hours after switch ing the ignit ion off, the
new values are included when ca lculating the cur­
rent trip information.
Un like the sho rt -term memory, the long-term
memory is not erased automatically. You can se­
l ect the time period for evaluating trip informa ­
tion yourself .
Fuel consumption
The current f uel consumption can be shown us­
i ng a bar graph ¢
fig. 8. The average consump­
tion stored in the short-term memory is also d is­
played. If the bar is green, your vehicle is sav ing
fuel through one of the following functions :
-Rec uperation : electrical energy can be stored in
the vehicle battery when the vehicle is coast ing
or driving down hill. T he bar will move toward
0.
-Cy linder on demand system*: the engine auto­
matically switches four cylinders (4 .0L TFSI) or
six cylinders (6.3L FSI) off when lower power
output is required and other conditions are
met. Th is change is not noticeable to the pas­
sengers . The cylinders w ill switch on aga in
when higher power output is needed .

Refrigerator
Introduction
A ppl ies to: ve hicles w ith re fri ge rato r
-
Clean the refrigerator before the first use r=;, table
on page 308.
You can on ly switch the refrigerator on, if :
- the temperature in the luggage compa rtme nt
is less t han 131 ° F (5 5 °C). If the refr igerator is
switched on, it will automatica lly switch off if
the temperature in the luggage compartment exceeds 131 ° F (55 °(). If the temperature
goes back below 131 ° F (55 °(), the refr igera­
tor will automatically switch on again.
Seat s and sto rag e
-The charge level of the vehicle battery is suffi ­
cient. The refrigerator is automatica lly switch­
ed off if the e lectr ica l system vo ltage falls be­
low the spec ified min imum value. Th is prevents
the vehicle battery from discharging. The re­
frigerator automatically switches back on if the
electrical system voltage increases aga in, for
examp le after starting the vehicle .
When the cooling function is working opt imally,
the cooling funct ion reaches 43° F (+6 °() and
the freez ing funct ion reaches 21 ° F (-6 °() . The
cooling temperature in the refrigerator also de­
pends on the luggage compartment tempe ra­
tu re . When the temperatu re in t he luggage com ­
partment is hig h, there may on ly be a limited
cooling effect.
A WARNING
= -
To avoid any injury risks to the passengers
caused by the refrigerator, the following safe­
ty precautions must be followed:
- The maximum load capacity for the freezer
is 5.5 lbs (2.5 kg).
- Never overload the refrigerator. There
is a
risk of injury in the event of a co llision or
sudden braking.
- The refrigerator cover must always be
closed and locked whi le driving. The refr ig­
erator contents could enter the vehicle inte­
rior dur ing a coll is ion or sudden brak ing ma­
neuver, wh ich increases the r isk of injury.
- Never store flammable fluids, gas contain­
ers and similar objects in the refrigerator
due to the r isk of an explos ion . This also ap­
plies to goods and products that can emit
volat ile or flammab le gases.
- At temperatu res of 32° F (0 °C) and lower
frozen liquid inside glass containe rs ca n
cause t he containe rs to b urst.
@ Note
,
- T he ve ntilation openings for the refrigerator
are at the rear panel tr im panel in the lug­
gage compa rtme nt and must not be cov­
ered.
