The switches are located in both doors.
We recommend to adjust the power seat in the following 
order:
1Seat adjustment, fore/aft
Press the switch (fore/aft direction) until a 
comfortable seating position is reached that still 
allows you to reach the accelerator/brake pedal 
safely. The position should be as far rearward as 
possible, consistent with ability to properly operate 
controls.Note:
Do not move the front passenger seat completely 
forward if objects are stored in the parcel net in the 
front passenger side footwell. Items in the net may be 
damaged.
2Seat, up/down
Press the switch (up/down direction) until 
comfortable seating position with still sufficient 
headroom is reached.
3Seat cushion tilt
Press the switch in the direction of the arrow until 
yo ur l egs a re sligh tly su p po rted.
4Backrest tilt
Press the switch in the direction of the arrow until 
your arms are slightly angled when holding the 
steering wheel.
5Seat cushion depth
Press the switch fore or aft until your legs are 
supported comfortably.

Te ch n ica l
data Instruments 
and controlsOperationDrivingInstrument 
cluster displayPractical hints Car care Index Stopping
For brief stops, e.g. at traffic lights, leave the 
transmission in gear and hold vehicle with the service 
brake.
For longer stops with the engine idling, shift into “N” 
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not 
hold it with the accelerator, use the brake. This avoids 
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a 
parking space, control the vehicle speed by gradually 
releasing the brakes. Accelerate gently and never 
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow), 
alternately shift from forward to reverse, while applying 
slight partial throttle.Rocking a vehicle free in this manner may cause the 
ABS or traction system malfunction indicator lamp to 
come on. Turn off and restart the engine to clear the 
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever 
not fully engaged in position “P” is dangerous. 
Also, when parked on an incline, position “P” alone 
may not prevent your vehicle from moving, 
possibly hitting people or objects.Always set the parking brake in addition to shifting 
to position “P”, see page 238 for parking brake. When parked on an incline, also turn front wheel 
against curb.Wa r n i n g !
When leaving the vehicle always remove the 
electronic key from the starter switch, take the 
KEYLESS-GO-card (if so equipped) with you and 
lock the vehicle. Do not leave children unattended 
in the vehicle, or with access to an unlocked 
vehicle. Children could move the gear selector lever 
from position “P”, which could result in an 
accident or serious injury.

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 
selector lever to position “N”. Try to keep the vehicle 
under control by corrective steering action.
Road salts and chemicals can adversely affect braking 
efficiency. Increased pedal force may become necessary 
to produce the normal brake effect. We therefore 
recommend depressing the brake pedal periodically 
when traveling at length on salt-strewn roads. This can 
bring road salt impaired braking efficiency back to 
normal. A prerequisite is, however, that this be done 
without endangering other drivers on the road.If the vehicle is parked after being driven on salt treated 
roads, the braking efficiency should be tested as soon as 
possible after driving is resumed while observing the 
safety rules in the previous paragraph.
Wa r n i n g !
If the vehicle becomes stuck in snow, make sure 
that snow is kept clear of the exhaust pipe and 
from around the vehicle with engine running. 
Otherwise, deadly carbon monoxide (CO) gases may 
enter vehicle interior resulting in unconsciousness 
and death.To assure sufficient fresh air ventilation, open a 
window slightly on the side of the vehicle not 
facing the wind.

Distance notification function
Even if Distronic is deactivated, the distance to the 
vehicle ahead continues to be measured, see page 266 
for multifunction display.
The Distronic lamp in the speedometer dial illuminates 
to advise the driver of a situation which under normal 
braking conditions and dry surfaces should have been 
addressed by the driver.
The distance notification function can be activated 
separately, see page 265. It operates when driving at 
speeds above approx. 25 mph (Canada: 30 km/h).
When recognizing a stationary obstacle or a slower 
vehicle moving in the vehicle’s path and the danger of a 
collision exists, the distance warning lamp in the 
speedometer dial lights up and simultaneously a 
continuous warning sounds.
Note:
Model CL 55 AMG only:
Distance notification function is deactivated if the 
vehicle speed exceeds approximately 160 mph 
(260 km/h).Important!
With the Distronic switched off, only the distance 
notification function operates, meaning the vehicle does 
not slow down.
Important!
Complex driving situations are not always fully 
recognized by Distronic, which could result in wrong or 
missing distance warnings.
See page 261 for additional driving hints.
Wa r n i n g !
If the distance warning lamp in the speedometer 
dial lights up while driving and a continuous 
warning sounds, immediate attention on the part of 
the driver is required.As required by the traffic situation, apply the 
service brakes and navigate around a possible 
obstacle. However, do not drive by relying on the 
distance notification function as that will result in 
an emergency braking application which, 
especially depending on road surface conditions 
and driver reaction, will not always be able to avoid 
a collision.

Te ch n ica l

Important!
The ABS improves steering control of the vehicle during 
hard braking maneuvers.
The ABS prevents the wheels from locking up above a 
vehicle speed of approximately 5 mph (8 km/h) 
independent of road surface conditions.At the instant one of the wheels is about to lock up, a 
slight pulsation can be felt in the brake pedal, 
indicating that the ABS is in the regulating mode. Keep 
firm and steady pressure on the brake pedal while 
experiencing the pulsation.
Continuous steady brake pedal pressure results in 
applying the advantages of the ABS, namely braking 
power and ability to steer the vehicle.
In the case of an emergency brake maneuver keep 
continuous full pressure on the brake pedal. In this 
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even 
with light brake pedal pressure because of the 
increased likelihood of locking wheels. The pulsating 
brake pedal can be an indication of hazardous road 
conditions and functions as a reminder to take extra 
care while driving.
Wa r n i n g !
Do not pump the brake pedal, rather use firm, 
steady brake pedal pressure. Pumping the brake 
pedal defeats the purpose for ABS and significantly 
reduces braking effectiveness.
