Important notice for California retail
buyers and lessees of Mercedes-Benz automobiles
Under California law you may be entitled to
a replacement of your vehicle or a refund
of the purchase price or lease price, if
Mercedes-Benz USA, LLC and / or its au-
thorized repair or service facilities fail to fix
one or more substantial defects or mal-
functions in the vehicle that are covered by
its express warranty after a reasonable
number of repair attempts. During the pe-
riod of 18 months from original delivery of
the vehicle or the accumulation of
18 000 miles (approx. 29 000 km) on the
odometer of the vehicle, whichever occurs
first, a reasonable number of repair at-
tempts is presumed for a retail buyer or
lessee if one or more of the following oc-
curs: (1) the same substantial defect or mal-
function results in a condition that is
likely to cause death or serious bodily
injury if the vehicle is driven, that de-
fect or malfunction has been subject to
repair two or more times, and you have
directly notified Mercedes-Benz USA,
LLC in writing of the need for its repair,
(2) the same substantial defect or mal-
function of a less serious nature than
category (1) has been subject to repair
four or more times and you have direct-
ly notified us in writing of the need for
its repair, or(3) the vehicle is out of service by reason
of repair of the same or different sub-
stantial defects or malfunctions for a
cumulative total of more than
30 calender days. Written notification
should be sent to us, not a dealer, at
Mercedes-Benz USA, LLC, Customer

During severe operating conditions,
e.g. stop-and-go traffic, the coolant tem-
perature may rise close to 248°F (120°C),
i.e. close to the red zone of the tempera-
ture gauge.
The engine should not be operated with
the coolant temperature above 248°F
(120°C), i.e. in the red zone of the coolant
temperature gauge. Doing so may cause
serious engine damage which is not cov-
ered by the Mercedes-Benz Limited War-
ranty.
Trip odometer
Make sure you are viewing the trip
odometer display.
If it is not displayed, press the è or
ÿ button on the multifunction
steering wheel repeatedly until the trip
odometer appears (
page 134).
Press and hold reset button on the in-
strument cluster (
page 22) until the
trip odometer is reset.
Warning!
G
Driving when your engine is badly over-
heated can cause some fluids which
may have leaked into the engine com-
partment to catch fire. You could be se-
riously burned.
Steam from an overheated engine can
cause serious burns and can occur just
by opening the hood. Stay away from
the engine if you see or hear steam com-
ing from it.
Turn off the engine, get out of the vehicle
and do not stand near the vehicle until the
engine has cooled down.
iExcessive coolant temperature triggers
a warning in the multifunction display
(page 323).
134 Controls in detailControl system
Control systemThe control system is activated as soon as
the SmartKey in the starter switch is
turned to position1 or as soon as the
KEYLESS-GO start/stop button* is in
position1. The control system enables you
to:
call up information about your vehicle
change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to set the language for
messages in the instrument cluster dis-
play, and much more.
The control system relays information to
the multifunction display.

Warning!
G
A driver’s attention to the road and traffic
conditions must always be his /her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.
