Instruments and indicator lights
(+S °C), a snowflake symbol appears in front of
the temperature display.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en­
gine.
A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+S
0
()
and that ice can increase the risk of accidents .
@ Tips
You can change the measurement units, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ q page 10, fig. 3 only works when
the ignition is switched on. When the display has reached the reserve mark, the bottom LED will
turn red and the
tj] indicator light turns on
q page 24. Th e bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level~
page 29, On-board comput­
er display.
For the tank capacity in your vehicle , refer to the
Technical Data
qpoge 303.
(D Note
Never drive until the tank is completely emp­
ty . The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
t or, an indicator light . will turn on when the
12
coolant temperature is too high q page 20. Re­
fer to
q 0 .
The coolant temperature indicator @ q page 10,
fig. 3
only works when the ignition is switched
on. To prevent engine damage, please observe
the following notes about the temperature rang­
es .
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, full ac­
ce lerating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
T his is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
q page 20 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment . This increases the risk of
burns . Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area. Stop the engine and
allow it to cool before working in the engine
compartment. Always follow the informa­
tion found in¢
page 236, Working in the

Always distribute loads evenly. Make sure any­
thing on the roof rack is securely tied down .
11-Always distribute the loads on the roof rack
evenly .
11-Always attach items to the roof rack securely
before you drive off.
The maximum permiss ible roof weight is
165 lb
( 7 5 kg ). The roof weight is the total of the
weight of the roof rack, the attachments and the
cargo you are carrying. You must also not exceed
the maximum load weight fo r th e roof rac k you
are using.
When us ing a roof rack system wh ich has a lower
l oad carry ing capacity, you must not use up the
to ta l maximum permissible load car rying capaci­
ty specified above. Instead, you s hou ld load the
r oof rack system only to the maximum capac ity
specified by the manufacturer of the roof rack
system .
A WARNING
Weak, damaged or improper straps used to
secure items to the roof rack can fa il during
hard braking or in a collision and cause seri­
ous personal injury.
- Make sure the roof rack is installed exactly
as spec ified above

-Make sure that the selector lever is in the P
position and the ignition is switched off
when leaving the vehicle.
([) Note
-The high-voltage system can be damaged if
the vehicle underbody comes into contact
with the ground. Immediately drive your ve­
hicle to an authorized repair facility and
have it inspected.
- The electric drive motor can become very
hot during operation . Do not stop the vehi­

cle.
Special considerations for the high-voltage
battery
Please first read and note the introductory infor­
mation and heed the warnings
¢page 98.
All batteries age with use and over time. There
are things you should know about the care of the
high-voltage battery that will help it keep giving
you good service and reliability over time. Please
read and keep the following information in mind
while you enjoy the performance and economy of
your vehicle.
- Be sure to charge the high-voltage battery be­
fore leaving the vehicle parked and unused for a
longer period of time. Ideally the high-voltage
battery should have a charge level between
40% and 60% when parked for a long time.
- If the battery charge level is below 3%, never
park the vehicle for more than 21 days without
charging the high-voltage battery. Should you
have to park the vehicle for a long time, make
sure that the charge level is sufficient to help
prevent the battery from aging prematurely.
- Frequent and consecutive charging of the high­
voltage battery when the charge level is above
98% can also decrease the capacity of the high-
e-tron
voltage battery. Make sure the charge level is
below 98% when you start the charging proc­
ess.
- Should the vehicle be parked for longer than
2 days at temperatures below -13 °F (-25 °(),
the high-voltage battery could freeze and not
be able to provide energy to the electric motor.
The battery will start working again, once it
warms up . The battery can be warmed up when
the outside temperature rises or when the vehi­
cle is garaged appropriately. The battery will al­
so warm up when being used (switching on the
air conditioner, the heater or by driving the ve­
hicle). Should you have to park your vehicle at
very low temperatures for longer than 1 day,
make sure that the high-voltage battery does
not freeze by parking the vehicle in a garage
that is heated or protected from the outside
temperature.
- The high-voltage battery can be damaged and
the capacity can be decreased when the vehicle
is parked for longer than 24 hours when the
ambient temperature is higher than 118 °F
(48 °C). Always make sure that the high-volt­
age battery is not exposed to temperatures
above 118 °F (48 °C) for a long time.
- Never park the vehicle in areas that are likely to
be flooded, such as beaches or river banks, and
never drive the vehicle in WATER, on flooded
roads or through water that is higher than the
bottom of the vehicle body. The high-voltage
battery, along with other vehicle components,
can be damaged severely if the high-voltage
battery is exposed to open water especially for
a longer time. However, you can drive through
water on roads under certain conditions
¢ page 77, Driving through water on roads .
Failure to heed any of these requirements can
age the battery prematurely and lead to a perma­
nent decrease of the high-voltage battery's ca­
pacity.
(D Tips
Always make sure that the high-voltage bat­
tery is not exposed to extremely low and high
temperatures as well as to water especially
for a longer time. Failure to protect and care
for the high-voltage battery can lead to

Climate control
Description
Applies to vehicles: with plug- in hybrid drive
Your vehicle has either auxiliary heating or auxili­
ary heat ing/ air conditioning*.
The auxiliary heating or the auxi liary heating/ air
conditioning* switches on depending on the out­
side temperature and the temperature set on the
climate control unit .
Switching on/off immediately
.,. You can switch the climate control on and off
immediately in the MMI*
¢page 123. Or
.,. Switch off the blower with the~ button
¢ page 72, fig. 72.
Setting the timer
.,. You can set the time when your vehicle should
reach the desired temperature. Your set tem­
perature and the outside temperature deter­
mine when the climate control switches on.
@ Tips
- The temperature that the climate control
system adjusts to depends on the last tem­
perature you set in the climate control unit
c;;,page 72.
-The climate control system does not auto­
matically switch on or off earlier if the vehi­
cle battery charge or the fuel level is too low.
122
· Auxiliary climate control
Applies to vehicles: with plug-in hybrid drive without auxiliary
hea ting
The aux iliary climate control controls the tem­
perature in the vehicle inter ior ent irely with elec­
tric power. It turns on only if the high-voltage
battery charge level is sufficient and there is
enough fuel in the tank.
Auxiliary heating / air conditioning
Applies to vehicles: with plug-in hybrid drive and auxiliary
heat ing
The aux iliary heating/ air conditioning controls
the temperature in the vehicle interior if the
high-voltage battery charge level is suff icient and
there is eno ugh fuel in the tank.
The
.ill. symbo l blinks in the climate contro l unit
whe n auxiliary heating is switched on.
When the auxiliary heating/ air conditioning t im­
er is programmed, the Ill symbol stays turned on
until the departure t ime is reached.
& WARNING
- To reduce the risk of poisoning, the auxiliary
heating/ air conditioning must not run in
confined spaces .
- To redu ce the risk of fires, the auxiliary
heating/ air conditioning must not run
when refueling.
- Due to the high temperatures that result
from operating the auxiliary heating/ air
conditioning, the vehicle must be parked in
a way so that the hot exhaust can escape at
the bottom of the engine cover without ob­
struction. The exhaust must not come into
direct contact with highly flammab le mate­
r ials.
(D Tips
Water vapor can build up near the engine
compartment when outside temperatures are low. This is a natural phenomenon and is no
cause for concern.

Checking and Filling
Refueling
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you can
still open the flap manually· for deta iled instruc­
tions see~
page 232 .
You can find the fuel tank capacity of your vehicle
in
c::;, page 303 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle . For more in­
formation about fuel specifications, see
c::;, page 228 .
Your vehicle fuel tank has an onboard refuelling
vapor recovery system . This feature helps to pre·
vent fuel vapors from escap ing from the tank and
polluting the environment while you refuel your
veh icle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully .
.&, WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
full or empty, may leak and could cause a fire
in a collision. If you must transport fuel to

A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, exp lo­
sions or serious in juries.
- Fuel ignites eas ily and can cause serious
burns and other injuries.
-
- If you do not switch the eng ine off when fu­
eling and/or do not insert the fuel nozz le
completely into the tank opening, fuel can
leak out or run over . Leaked fuel can ignite
and sta rt a fi re .
- Do not use the telephone while fueling. The electromagnet ic rays can cause spa rks,
w hich can ignite fuel vapors and sta rt a fi re .
- Do not s it in you r vehicle while fueling . If
yo u must make an except io n and enter your
vehicle again wh ile fue ling , close the door
and touch met al to discharge static electri c­
ity befo re touching the fue l nozzle. Static
elect ricity can create sparks, whic h can ig ­
nite vapors when f ue li ng.
- Do not smoke or have an open flame i n the
area when fueling your vehicle or filling a
fuel container because this increases the risk of an explos ion.
- For your safety, carrying f uel containers in
your vehicle is not recommended. Whether
full or empty, the conta iner can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­ port a fuel container, note the following:
- Never fill the fuel containe r with fuel
while it is in or on the vehicle. S tat ic elec­
t ricity is d isc har ged when filling wh ich can
Ch eck ing and Filling
cause the fuel vapors to ignite and in­
creases the risk of an exp losion.
- Always place a fue l container on t he
ground before fill ing .
- Always hold the fue l nozzle completely in
the fuel conta iner when fill ing.
- If the fuel containe r is made of meta l, the
fuel nozzle must always be in contact with
the container when filling it with f uel. This
~revents static elect ricity from discharg­
ing .
- Never spill fue l in the vehicle or the lug­
gage compartment. Evaporated fuel is ex­
plosive and increases the risk of serious in­
jury or death .
- Fo llow lega l requirements when using,
stor ing and transporting fuel containers .
- Make su re the f uel container conforms to
industry standards (ANSI/ASTM F852-86).
(D Note
- Remove spilled fue l from vehicle pa int im­
mediately, because it can damage paint.
- Never drive unt il the fuel tank is complete ly
empty. The irreg ular s upply of fue l that re ­
sults from that can cause eng ine misfires.
Uncombusted fuel will enter the exhaust
system and increase the risk of damage to
t he cata lytic converter .
- If the fuel tank runs complete ly empty in a
vehicle with a
diesel engine , the ignition
must remain switched on fo r at least 30
seconds afte r refueli ng before starti ng the
eng ine.
It may t ake longer than u sual fo r
t he engine to s tart, even up to a minute .
T his is because t he air must f irst b leed ou t
of the fue l system when starting the engine.
@ For the sake of the environment
- If the fue l nozzle is use d co rrectly, it w ill in­
dica te t hat the t ank is full the first t ime it
switches off a utomatica lly. Do not try to
add more fuel, because it can spill ove r. A l­
so, the expansion space in the tank w ill fill
'
w hich can resu lt in fuel sp illing out when it
becomes wa rm and pollut ing the e nviron­
ment.
