Introduction
The
cruise control driving system is described
on the following pages.
The driving safety systems ABS, BAS and
ESP ®
are described in the “Safety and
security” section (Y page 47). Cruise control
The cruise control maintains the speed you
set for your vehicle automatically.
The

use of the cruise control is recommended
for driving at a constant speed for extended
periods of time. The currently set speed or last set speed
(“Resume” function) appears in the status
indicator of the multifunction display:
R
USA only: e.g. CRUISE 55 Miles
R Canada only: e.g. ¯ 90 Km/h G
Warning!
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle’s speed
and for safe brake operation.
Only

use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
R The use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
R The use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
R Deactivate the cruise control when driving
in fog.
The “Resume” function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed. G
Warning!
When the cruise control is braking, the brake
pedal is retracted (i.e. depressed
automatically). The pedals’ range of motion
must not be impeded by any obstacles:
R Do not place any objects in the footwell.
R Make sure that the floormats and carpets
are securely in place.
R Do

not rest your foot underneath the brake
pedal, as it could otherwise be trapped.
You could otherwise cause an accident and
injure yourself and/or others. Driving systems

i On uphill grades, the cruise control may
not be able to maintain the set speed. Once
the grade eases, the set speed will be
resumed. On downhill grades, the cruise control
maintains the set speed by braking with the
vehicle’s brake system.
Vehicles with automatic transmission:
In addition, on longer downhill grades the
automatic transmission will downshift
automatically.
i Vehicles with manual transmission:
If you depress the clutch pedal when
shifting into another gear, the engine speed
may increase.
R Always drive with sufficient, but not
excessive, engine speed.
R Shift the gear in a timely manner.
R Avoid shifting down more than one gear
if at all possible.

Depressing the accelerator pedal does not
deactivate the cruise control. After a brief
acceleration (e.g. for passing), the cruise
control will resume the last set speed.
Changing the set speed G
Warning!
Keep in mind that it may take a brief moment
until the vehicle has made the necessary
adjustments.
Increase

or decrease the set vehicle speed to
a value that the prevailing road conditions and
legal speed limits permit. Otherwise, sudden
and unexpected acceleration or deceleration
of the vehicle could cause an accident and/
or serious injury to you and others.
When you use the cruise control lever to
decelerate, the brake system will brake the
vehicle automatically if the engine’s braking
power does not brake the vehicle sufficiently.
X Increasing: Lift the cruise control lever in
direction of arrow : and hold it up until
the desired speed is reached.
X Decreasing:
Press the cruise control lever
in direction of arrow ; and hold it down
until the desired speed is reached.
X Release the cruise control lever.
The new speed is set and the vehicle will
accelerate or decelerate. Fine adjustment in 1 mph (Canada:
1 km/h) increments

Setting stored speed (Resume
function) G
Warning!
The set speed stored in memory should only
be set again if prevailing road conditions and
legal speed limits permit. Possible
acceleration or deceleration differences
arising from returning to the preset speed
could

cause an accident and/or serious injury
to you and others.
X Briefly pull the cruise control lever in

Climate control system
Overview of climate control system functions
Your vehicle is equipped with either of the following climate control systems: Climate control
(Y page 162) Automatic climate control
(Y page 163)The climate control combines a heating and
ventilation system with a cooling system. The automatic climate control combines an
automatic heating and ventilation system
with a cooling system. You can adjust the
automatic climate control separately for the
driver’s and passenger side.

Notes on climate control system
The climate control system is operational
whenever the engine is running. You can
operate the climate control system in either
the automatic 9
or manual mode. The system
cools or heats the interior depending on the
selected interior temperature.
It can only function optimally when you are
driving with the windows and the retractable
hardtop closed.
Nearly

all dust particles, pollutants and odors
are filtered out before outside air enters the passenger compartment through the air
distribution system. G
Warning!
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its

scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.

The air conditioning is operational while the
engine

is running and cools the interior air to
the temperature set by the operator. In
addition, the air conditioning dehumidifies
the interior air and helps prevent window
fogging. G
Warning!
If you deactivate the air conditioning, the
vehicle will not be cooled when weather
conditions

are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.
i Condensated water may drip out from
underneath the vehicle. This is normal and
not an indication of a malfunction.
The air conditioning uses the refrigerant
R134a. This refrigerant is free of CFCs which
are harmful to the ozone layer.

conditioning. The interior air will then no
longer be cooled or dehumidified.

Warning!
When operating the climate control, the air
that enters the passenger compartment
through the air vents can be very hot or very
cold

(depending on the set temperature). This
may cause burns or frostbite to unprotected
skin in the immediate area of the air vents.
Always keep sufficient distance between
unprotected parts of the body and the air
vents. If necessary, use the air distribution
adjustment to direct the air to air vents in the
vehicle interior that are not in the immediate
area of unprotected skin.
For best possible performance of the climate
control:
X Keep the air intake grille in front of the
windshield

free of snow, leaves, sticks, and
any other debris.
X Always keep all air vents and grilles in the
passenger compartment free from
obstruction.
