Manual gear shifting
General notes
You can change gear yourself using the steer-ing wheel paddle shifters. The transmissionmust be in position [to do this.
Depending on which steering wheel paddleshifter is pulled, the automatic transmissionimmediately shifts into the next gear down orup, if permitted.
To use manual shifting, you have two options:
Rtemporary setting
Rpermanent setting
If you activate manual gearshifting, the multi-function display will show the current gearinstead of transmission position [.
If manual gearshifting is deactivated, the gearswill be selected automatically.
Temporary setting
XTo activate:shift the selector lever to [.
XPull steering wheel paddle shifter Cor D.
The temporary setting is active for a certainamount of time. Under certain conditions, theminimum amount of time is extended, e.g. inthe case of lateral acceleration, during overrunmode or when driving on steep terrain.
XTo deactivate:pull steering wheel paddleshifter Dand hold it in place.
or
XUse the lever to switch the transmissionposition.

XTo shift up:pull steering wheel paddleshifter D.The automatic transmission shifts up to thenext gear.
If the maximum engine speed in the cur-rently engaged gear is reached and you con-tinue to accelerate, the automatic transmis-
sion automatically shifts up in order to pre-vent engine damage.
XTo shift down:pull steering wheel paddleshifter C.The automatic transmission shifts down tothe next gear.
Automatic down shifting occurs when coast-ing.
If the engine were to exceed the maximumengine speed when shifting down, the auto-matic transmission protects against enginedamage by not shifting down.
Mercedes-AMG vehicles
!If manual gearshifting is permanently acti-vated, the automatic transmission does notshift up automatically even when the enginelimiting speed for the current gear isreached. When the engine limiting speed isreached, the fuel supply is cut to preventthe engine from overrevving. Always makesure that the engine speed does not reachthe red area of the tachometer. There is oth-erwise a risk of engine damage.

148Parking
Driving and pa rking
Page 155 of 330
New and replaced brake pads and discs onlyreach their optimum braking effect after sev-eral hundred kilometers of driving. Compen-sate for this by applying greater force to thebrake pedal. Keep this in mind, and adapt yourdriving and braking accordingly during thisbreak-in period.
Excessive heavy braking results in correspond-ingly high brake wear. Observe the brake sys-tem warning lamp in the instrument clusterand note any brake status messages in themultifunction display. Especially for high per-formance driving, it is important to maintainand have the brake system checked regularly.
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth onthe road surface, there is a danger of hydro-planing occurring.
For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Do not drive through flooded areas. Checkthe depth of any water before drivingthrough it. Drive slowly through standingwater. Otherwise, water could enter thevehicle interior or engine compartment. Itcan then damage the engine's or automatictransmission's electronic components. Itcan also be sucked in by the engine's airintake connection and cause engine dam-age.
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter
the vehicle. This is the case, e.g. if the vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing running, make sure the exhaust pipe and
area around the vehicle are clear of snow.
To ensure an adequate supply of fresh air,
open a window on the side of the vehicle
that is not facing into the wind.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position \\.
The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especiallyin wooded areas or on bridges. The vehiclecould skid if you fail to adapt your drivingstyle. Always adapt your driving style and driveat a speed to suit the prevailing weather condi-tions.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.

Setting a speed
Keep in mind that it may take a brief momentuntil the vehicle has accelerated or braked tothe speed set.
XTo adjust the set speed in 1 mph incre-ments (1 km/h increments):briefly pressthe cruise control lever up Cto the pres-sure point for a higher speed, or down Dfor a lower speed.Every time the cruise control lever ispressed up or down, the last speed stored isincreased or reduced.
XTo adjust the set speed in 5 mph incre-ments (10 km/h increments):brieflypress the cruise control lever up Cpast thepressure point for a higher speed, ordown Dfor a lower speed.Every time the cruise control lever ispressed up or down, the last speed stored isincreased or reduced.
Setting a specified minimum distance
You can set the specified minimum distancefor Active Distance Assist DISTRONIC by vary-ing the time span between one and two sec-onds. This determines the distance that ActiveDistance Assist DISTRONIC is to maintain fromthe vehicle in front, depending on the roadspeed. You can see this distance in the multi-function display (Ypage 160).
The specified minimum distance can bechanged while Active Distance AssistDISTRONIC is switched on or off.
Make sure that you maintain a sufficiently safedistance from the vehicle in front. Adjust thedistance to the vehicle in front if necessary.
