244 Controls in detailDriving systemsThe driving system of your vehicle is
described on the following pages:
Cruise control, with which the vehicle
can maintain a preset speed.
The BAS, ABS and ESP driving systems are
described in the “Safety and Security” sec-
tion (page 80).
Cruise control
The 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 25 mph (40 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
The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must remain at
all times responsible for the vehicle 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 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 the cruise control when driv-
ing 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.

4Resume to last set speedSetting current speed
Accelerate or decelerate to the desired

Briefly lift1 or depress2 the cruise

The cruise control is activated.
The selected speed appears in the multi-

Warning!
G
Cruise control brakes automatically so that
the set speed is not exceeded. The brake
pedal is depressed automatically to do this.
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 braking operation.
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.

Canceling cruise control
There are several ways to cancel the cruise
control:
Step on the brake pedal.
The cruise control is canceled. The last
speed set is stored for later use.
or
Briefly push the cruise control lever in
direction of arrow3 (
page 245).
The cruise control is canceled. The last
speed set is stored for later use.
iOn uphill or downhill 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
will hold the set speed with active brak-
ing action.
In addition, on longer downhill grades
the automatic transmission* will auto-
matically downshift.
iVehicles with manual transmission:
If you depress the clutch pedal when
shifting into another gear, the engine
speed may increase.
Drive with sufficient engine speed.
Shift gears in a timely manner.
If possible, do not shift down more
than one gear.
iThe last stored speed is canceled when
you turn off the engine.

Setting a higher speed
Lift the cruise control lever in direction
of arrow1 (
page 245) 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 245) and
hold it down until the desired speed is
reached.
Release the cruise control lever.
The new speed is set.
iThe cruise control switches off auto-
matically, if
you step on the brake pedal.
you pull up the parking brake lever
firmly.
the vehicle speed is below 25 mph
(40 km/h).
ESP is in operation or switched off
with the ESP switch (
page 82).
Vehicles with manual transmission:
you depress the clutch pedal for
longer than six seconds during
shifting into another gear.
Vehicles with automatic transmis-
sion*: you move the gear selector
lever to positionN while driving.
!Vehicles with automatic transmission*:
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 the cruise control. After
brief acceleration (e.g. for passing), the
cruise control will resume the last
speed set.
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.

Briefly tip the cruise control lever in
direction of arrow1 (
page 245).
Slower
Briefly tip the cruise control lever in
direction of arrow2 (
page 245).Setting to last stored speed
(“Resume” function)
Briefly pull the cruise control lever in
direction of arrow4 (
page 245).
The cruise control resumes the last set
speed.
Remove your foot from the accelerator
pedal.
The last set speed appears in the multi-
function display.
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.

Driving instructions
SLK 350
SLK 350 with Sport Package*
Your vehicle is factory equipped with
“W”-rated tires, which have a tire speed
rating of 168 mph (270 km / h).
An electronic speed limiter prevents your
vehicle from exceeding a speed of
155 mph (250 km/h).SLK 55 AMG
Your vehicle is factory equipped with
“Y”-rated tires, which have a tire 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 positionN or
declutch in case of manual transmission.
Try to keep the vehicle under control by
corrective steering action.
iFor information on speed rating for
winter tires, see “Winter tires”
(page 327).
For additional general information on
tire speed markings on tire sidewall,
see “Tire speed rating” (
page 313).
iFor information on driving with snow
chains, see “Snow chains”
(page 328).
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.
