Driving systems
Driving systems
The driving systems of your vehicle are de-
scribed on the following pages:

Cruise control, with which the vehicle
can maintain a preset speed.


Parktronic* (Canada only), which
serves as a parking assistant.
For information on the BAS, ABS, and ESP
®
driving systems, see “Driving safety sys-
tems” (
page 87).
Cruise control
Cruise control automatically maintains the
speed you set for your vehicle.
Use of cruise control is recommended for
driving at a constant speed for extended
periods of time.
You can set or resume cruise control at any
speed over 20 mph (30 km/h).
The cruise control function is operated by
means of the cruise control lever.
The cruise control lever is the uppermost
lever on the left-hand side of the steering
column (
page 22).
Warning!
G
Cruise control is a convenience system de-
signed to assist the driver during vehicle op-
eration. The driver is and must remain at all
times responsible for the vehicle speed and
for safe brake operation.
Only use cruise control if the road, traffic
and weather conditions make it advisable to
travel at a steady speed.

The use of cruise control can be danger-
ous on winding roads or in heavy traffic
because conditions do not allow safe
driving at a steady speed.


The use of cruise control can be danger-
ous on slippery roads. Rapid changes in
tire traction can result in wheel spin and
loss of control.


Deactivate cruise control when driving
in fog.
The “Resume” function should only be oper-
ated if the driver is fully aware of the previ-
ously set speed and wishes to resume this
particular preset speed.

266 Controls in detailDriving systems1Set current or higher speed
2Set current or lower speed
3Cancel cruise control
4Resume to last set speed
Setting current speed

Accelerate or decelerate to the desired
speed.

Briefly lift1 or depress2 the cruise
control lever (
page 266).
The current speed is set.

Remove your foot from the accelerator
pedal.
Cruise control is activated.The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated.
Warning!
G
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal depresses when the cruise control en-
gages the brakes.
Keep driver’s foot area clear at all times, in-
cluding the area under the brake pedal. Ob-
jects stored in this area may impair pedal
movement which could interfere with the
braking ability of the cruise control system.
Do not place your foot under the brake pedal
- your foot could become caught.
Keep in mind that cruise control is a conve-
nience system designed to assist the driver
during vehicle operation. The driver is and
must always remain responsible for the ve-
hicle’s speed and for safe brake operation.
iOn uphill or downhill grades, 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
will hold the set speed with braking
from the vehicle’s brake system.
In addition, on longer downhill grades
the automatic transmission will auto-
matically downshift.

Canceling cruise control
There are several ways to cancel cruise
control:
Step on the brake pedal.
Cruise control is canceled. The last
speed set is stored for later use.
or

Briefly push the cruise control lever to
position3.
Cruise control is canceled. The last
speed set is stored for later use.iThe last stored speed is canceled when
you turn off the engine.
iCruise control automatically switched
off, if

you step on the brake pedal.


you press the parking brake pedal.
In this case the segments in the
multifunction display (
page 266)
go out and no warning sounds.

(30 km/h).

with the ESP
® switch (
page 90).


you move the gear selector lever to
positionN while driving.
The segments in the multifunction dis-
play (page 266) go out, and an
acoustic warning sounds.
!Moving gear selector lever to
positionN while driving also cancels
cruise control. However, the gear se-
lector lever should not be moved to
positionN while driving except to coast
when the vehicle is in danger of skid-
ding (e.g. on icy roads).iDepressing the accelerator pedal does
not deactivate cruise control. After
brief acceleration (e.g. for passing),
cruise control will resume the last
speed set.

268 Controls in detailDriving systemsSetting a higher speed
Lift the cruise control lever in direction
of arrow1 (
page 266) and hold it
up until the desired speed is reached.

Release the cruise control lever.
The new speed is set.
Setting a lower speed

Depress the cruise control lever in
direction of arrow2 (
page 266) and
hold it down until the desired speed is
reached.

Release the cruise control lever.
The new speed is set.Fine adjustment in 1 mph
(Canada: 1 km/h) increments
Faster

Briefly tip the cruise control lever in di-
rection of arrow1 (
page 266).
Slower

Briefly tip the cruise control lever in di-
rection of arrow2 (
page 266).Setting to last stored speed
(“Resume” function)

Briefly push cruise control lever to
position4 (
page 266).
The cruise control resumes the last set
speed.

Remove your foot from the accelerator
pedal.
The selected speed appears in the multi-
function display for approximately five sec-
onds, and the corresponding speedometer
segments from the selected speed to the
vehicle maximum speed are illuminated
(
page 266).
iWhen you use the cruise control lever
to decelerate, the brake system will
automatically brake the vehicle if the
engine’s braking power does not brake
the vehicle sufficiently.
Warning!
G
The speed stored in memory should only be
set again if prevailing road conditions per-
mit. Possible acceleration or deceleration
differences arising from returning to the pre-
set speed could cause an accident and/or
serious injury to you and others.

313 Operation
Driving instructions
CLK 350, CLK 500
Your vehicle is factory equipped with
“W”-rated tires, which have a speed rating
of 168 mph (270 km/h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
130 mph (210 km/h).
CLK 55 AMG
Your vehicle is factory equipped with
“Y”-rated tires, which have a speed rating
of 186 mph (300 km/h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
155 mph (250 km/h).
Winter driving instructions
The most important rule for slippery or icy
roads is to drive sensibly and to avoid
abrupt acceleration, braking and steering
maneuvers. Do not use the cruise control
system under such conditions.
When the vehicle is in danger of skidding,
move gear selector lever to position N. Try
to keep the vehicle under control by cor-
rective steering action.Road salts and chemicals can adversely af-
fect braking efficiency. Increased pedal
force may become necessary to produce
the normal braking effect.
Depressing the brake pedal periodically
when traveling at length on salt-strewn
roads can bring road-salt-impaired braking
efficiency back to normal.
If the vehicle is parked after being driven
on salt-treated roads, the braking efficien-
cy should be tested as soon as possible af-
ter driving is resumed.
iFor information on tire speed rating for
winter tires, see “Winter tires”
(page 359).
For additional general information on
tire speed markings on the sidewall,
see “Tire speed rating” (
page 346).
iFor information on driving with snow
chains, see “Snow chains”
(page 360).
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
Warning!
G
Make sure not to endanger any other road
users when carrying out these braking ma-
neuvers.
