2006 MERCEDES-BENZ E350 temperature control

229 Controls in detail
4-zone automatic climate control*
Rear climate control
The rear climate control is adjusted via the
front climate control panel (
page 217) or
(
page 216) or the rear climate control
panel.
The rear climate control panel is located in
the rear center console.
Setting the temperature
Use temperature control rocker
switches4 and6 to separately adjust
the air temperature on each side of the
rear passenger compartment.You should raise or lower the temperature
setting in small increments, preferably
starting at 72°F (22°C). The adjusted tem-
perature appears in the display 5. The
rear climate control will adjust to the set
temperature as fast as possible.
1Temperature, left

Adjust the temperature to the desired
setting for each side of the passenger
compartment using the left and right
temperature buttons.
The temperature in the rear passenger
compartment is adjusted automatical-

The power outlet is located in the rear pas-
senger compartment.

Heated steering wheel*
The steering wheel heating warms up the
leather area of the steering wheel.
The stalk is on the lower left-hand side of
the steering wheel.

Turn switch at the tip of stalk in direc-
tion of arrow3.
The steering wheel is heated. Indicator
lamp1 comes on.
iThe power outlet can be used to
accommodate 12V DC electrical ac-
cessories (e.g. air pump, auxiliary
lamps) up to a maximum of 180 W.
An additional power outlet is located on
the left side in the trunk.
iThe steering wheel heating is tempo-
rarily suspended while indicator
lamp1 remains on when

the temperature of the vehicle inte-
rior is above 86°F (30°C)


the temperature of the steering
wheel is above 95°F (35°C)
When these conditions do not apply
anymore, steering wheel heating con-
tinues.

308 OperationDriving instructionsTire traction
The safe speed on a wet, snow covered or
icy road is always lower than on a dry road.
You should pay particular attention to the
condition of the road whenever the outside
temperatures are close to the freezing
point.Mercedes-Benz recommends winter tires
(
page 358) with a minimum tread depth
of approximately
1/6 in (4 mm) on all four
wheels for the winter season to make sure
normal balanced handling characteristics.
On packed snow, they can reduce your
stopping distance compared to summer
tires. Stopping distance, however, is still
considerably greater than when the road is
not covered with snow or ice. Exercise ap-
propriate caution.
Tire speed rating
Regardless of the tire speed rating, local
speed limits should be obeyed. Use pru-
dent driving speeds appropriate to prevail-
ing conditions.
Warning!
G
If ice has formed on the road, tire traction
will be substantially reduced. Under such
weather conditions, drive, steer and brake
with extreme caution.
!Avoid spinning of a drive wheel. This
may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Even when permitted by law, never operate
a vehicle at speeds greater than the maxi-
mum speed rating of the tires.
Exceeding the maximum speed for which
tires are rated can lead to sudden tire fail-
ure, causing loss of vehicle control and pos-
sibly resulting in an accident and/or
personal injury and possible death, for you
and for others.

352 OperationTires and wheelsQuality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.
Treadwear
The treadwear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1
1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from the norm due to variations in driving
habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to low-
est, are AA, A, B, and C. Those grades rep-
resent the tire’s ability to stop on wet
pavement as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Temperature
The temperature grades are A (the high-
est), B, and C, representing the tire’s resis-
tance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high tem-
perature can cause the material of the tire
to degenerate and reduce tire life, and ex-
cessive temperature can lead to sudden
tire failure. The grade C corresponds to a
level of performance which all passenger
car tires must meet under the Federal Mo-
tor Vehicle Safety Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.

Warning!
G
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.

systems, including the radio and navi-
gation system, as well as other optional
equipment (CD changer, telephone,
etc.).
Control system
The control system is used to call up
vehicle information and to change
component settings. Information and
messages appear in the multifunction
display. The driver uses the buttons on
the multifunction steering wheel to
navigate through the system and to ad-
just settings.

Driving convenience system for auto-
matically maintaining the vehicle speed
set by the driver.
Curb weight
(
page 354)Distronic*
A driving convenience cruise control
system which helps the driver maintain
a pre-selected speed:


If there is no vehicle directly ahead,
the system operates in the same
way as conventional ->cruise con-
trol.


If a slower moving vehicle is ahead,
Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.

Electrohydraulic brake system
Electronically controlled hydraulic
braking system for increased braking
safety and comfort.Engine number
The number set by the manufacturer
and placed on the cylinder block to
uniquely identify each engine pro-
duced.
Engine oil viscosity
Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
