The engine drives the generator, wh ich generates
electricity; the fue l consumption also increases
with the demand for electricity. Therefore, switch
e lectrical equipment off when you no longer
need it. Examples of equipment that use a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other p roper-
ty.
CD Note
-Have your vehicle maintained properly and
i n accordance with the service recommenda­
tions in your Warranty
& Ma intenance book­
l et. Lack of proper maintenance as well as
i mproper use of the vehicle will impair the
function of the emission control system and
could lead to damage.
-Do not alter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
-Do not alter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission Control System and other
important vehicle components .

"' .... 0 0 :c ' Assistance systems Speed warning system
The speed warning system helps you to stay un­
der a specified maximum speed.
The speed warning system warns you if you are
exceeding the maximum speed that you have set.
A warning tone will sound as soon as your speed
exceeds the stored value slightly.
The. (USA models)/ . (Canada models) indi­
cator light and a message appear in the instru­
ment cluster display at the same time. The
•
• indicator light and the message turn off if the
speed falls back below the stored maximum
speed.
Setting a threshold is recommended if you would like to be reminded when you reach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener­
al speed limit or if there is a specified maximum
speed for winter tires.
Setting the warning threshold
The warning threshold is set in the Infotainment
system.
.. Select: I CARI function button > Car systems
contro l button > Driver assistance > Speed
warning.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit.

_.&. WARNING
-
-Always pay attention to the traffic around
you when the cruise control system is in op ­
eration. You are always responsible for your
speed and the distance between your vehi­
cle and other vehicles.
-For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of an accident.
-Switch the cruise control off temporarily
when driving in turning lanes, highway exits or in construction zones.
