Coolant temperature gauge
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.

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 (

Press and hold reset buttonJ 
(page 140) 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 359).

A driver’s attention to the road and traffic 
conditions must always be his/her primary 
focus when driving.

driver when traffic and road conditions per-
mit it to be done safely.

(approximately 50 km/h), your vehicle is 
covering a distance of 44 feet (approximate-
ly 14 m) every second.

A driver’s attention to the road must always 
be his/her primary focus when driving. For 
your safety and the safety of others, we rec-
ommend that you pull over to a safe location 
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the 
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from 
using a cellular telephone while driving a ve-
hicle.
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-

Never operate radio transmitters equipped 
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna) 
from inside the vehicle while the engine is 
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and/or 
personal injury.
