Offroad drive program
TheOff-roaddrive program is characterizedby the following:
Rthe vehicle exhibits optimal driving charac-teristics on easily negotiable off-road ter-rain.
Drive program E (Economy)
Drive programEis characterized by the follow-ing:
Rcomfort-oriented engine settings.
Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.
Rthe vehicle pulls away more gently inforward and reverse gears, unless the accel-erator pedal is depressed fully.
Rthe vehicle has improved driving stability,for example on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle beingdriven at lower engine speeds and thewheels being less likely to spin.
Rgliding mode is activated automaticallywhen engine-internal conditions are fulfilledand the accelerator is not depressed. At thesame time the transmission’s clutch opensand the vehicle rolls freely using its kineticenergy. As a result great distances can becompleted without the engine brake andfuel consumption reduced.
iThe availability of gliding mode depends onvarious factors, including the following:
Rthe engine and transmission temperature
Rthe downhill gradient
Rthe vehicle speed
Rperforming regular adaptation functions
When you depress the brake pedal, glidingmode is deactivated, depending on pedalpressure.
When you activate cruise control or ActiveDistance Assist DISTRONIC, gliding mode isnot available.

take advantage of engine braking. For thisyou must first activate manual gearshifting.This helps you to avoid overheating thebrakes and wearing them out excessively.
When you take advantage of engine braking,it is possible that a drive wheel will notrotate for some time, e.g. on a slippery roadsurface. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Briefly depressing the accelerator pedal ondownhill gradients while the manual drive pro-gramMis temporarily activated: the automatictransmission may switch to the last activeautomatic drive programEorS. The automatictransmission may shift to a higher gear. Thiscan reduce the engine's braking effect.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. This increases the stopping distance
and can even cause the braking system to
fail. There is a risk of an accident.
Never use the brake pedal as a footrest.
Never depress the brake pedal and the
accelerator pedal at the same time.
!Depressing the brake pedal constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately.Drive on for a short while. This allows the air-flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the firsttime. This may also occur after the vehicle hasbeen washed or driven through deep water.
You have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.
After driving on a wet road or having the vehi-cle washed, brake firmly while paying attentionto the traffic conditions. This will warm up the
brake discs, thereby drying them more quicklyand protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.
RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.
RCarefully depress the brake pedal and thebeginning and end of a journey.
RMaintain a greater distance to the vehicleahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up inthe instrument cluster and
Ryou hear a warning tone while the engineis running
Observe additional warning messages in themultifunction display.
The brake fluid level may be too low due tobrake pad wear or leaking brake lines.
Have the brake system checked immedi-ately. Consult a qualified specialist work-shop to arrange this.
!A function or performance test should onlybe carried out on a 2-axle dynamometer. Ifyou wish to operate the vehicle on such adynamometer, please consult a qualifiedspecialist workshop in advance. You couldotherwise damage the drive train or thebrake system.
!As the ESP®system operates automati-cally, the engine and the ignition must beswitched off (the SmartKey must be in posi-tion

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
!Bear in mind that vehicles traveling in frontor in the opposite direction create waves.This may cause the maximum permissiblewater depth to be exceeded.
Failure to observe these notes may result indamage to the engine, electrical systemsand transmission.
If you have to drive on stretches of road onwhich water has collected, please bear in mindthat:
Rin the case of standing water, the waterlevel may be no higher than the lower edgeof the vehicle body
Ryou should drive no faster than walking pace
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 or Active Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
XTry to bring the vehicle under control usingcorrective steering.
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.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
For more information on driving with snowchains, see (Ypage 307).
For more information on driving with summertires, see (Ypage 306).
Observe the notes in the "Winter operation"section (Ypage 306).
Off-road driving
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.

GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system. There
is a risk of fire.
When driving on an unpaved road or off-
road, check the vehicle underside regularly.
In particular, remove trapped plant parts or
other flammable material. Contact a quali-
fied specialist workshop immediately if dam-
age is detected.
!There is a risk of damage to the vehicle if:
Rthe vehicle becomes stuck, e.g. on a highcurb or an unpaved road
Ryou drive too fast over an obstacle, e.g. acurb, a speed bump or a pothole in theroad
Ra heavy object strikes the underbody orparts of the chassis
In situations like this, the body, the under-body, chassis parts, wheels or tires could bedamaged without the damage being visible.Components damaged in this way can unex-pectedly fail or, in the case of an accident,no longer withstand the loads they aredesigned to.
If the underbody paneling is damaged, com-bustible materials such as leaves, grass ortwigs can gather between the underbodyand the underbody paneling. If these materi-als come in contact with hot parts of theexhaust system, they can catch fire.
In such situations, have the vehicle checkedand repaired immediately at a qualified spe-cialist workshop. If on continuing your jour-ney you notice that driving safety isimpaired, pull over and stop the vehicleimmediately, paying attention to road andtraffic conditions. In such cases, consult aqualified specialist workshop.
The vehicle is only designed for easily negotia-ble off-road terrain and poor road surfaces.
When driving off-road, substances such assand, mud and water or water mixed with oilmay get into the brakes. This could result in areduced braking effect or in total brake failureand also in increased wear and tear. The brak-ing characteristics change depending on thematerial entering the brakes. Clean the brakesafter driving off-road. If you detect a reduced
braking effect or grinding noises, have thebrake system checked in a qualified specialistworkshop as soon as possible. Adapt yourdriving style to the different braking character-istics.
Driving off-road increases the likelihood ofdamage to the vehicle, which, in turn, can leadto failure of the mechanical assembly or sys-tems. Adapt your driving style to suit the ter-rain conditions. Drive carefully. Have damageto the vehicle rectified immediately at a quali-fied specialist workshop.
Do not shift into transmission position\\when driving off-road. You could lose controlof the vehicle if you attempt to brake the vehi-cle using the service brake. If the gradient istoo steep for your vehicle, drive back down inreverse gear.
General notes

Driving and parking

RDrive slowly and evenly, if necessary at awalking pace.
REnsure that the wheels are in contact withthe ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. Forsafety reasons, get out of the vehicle firstand survey the off-road route.
RCheck the depth of water before fording riv-ers and streams.
RWatch out for obstacles.
RTake care when turning on an uphill ordownhill slope or when driving across aslope. The vehicle could otherwise tip over.
RAlways keep the side windows and the pan-orama roof with power tilt/sliding panelclosed during the journey.
RDo not deviate from marked routes.
RDo not use the HOLD function when drivingoff-road, on steep uphill or downhill gradi-ents or on slippery or loose surfaces. TheHOLD function cannot hold the vehicle onsuch surfaces.
Checklist before driving off-road
XEngine oil level:check the engine oil leveland add oil if necessary.
When driving on steep gradients, the engineoil level must be sufficiently high to ensure acorrect oil supply in the vehicle.
XWheels and tires:check the tire treaddepth and tire pressure.
XCheck for damage and remove any foreignobjects, e.g. small stones, from the wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in aloss of tire pressure and damage the tirebead. Before driving off-road, check thewheels and replace them if necessary.
Checklist after driving off-road
!If you detect damage to the vehicle afterdriving off-road, have the vehicle checkedimmediately at a qualified specialist work-shop.
XDeactivate off-road program (Ypage 132).
XDeactivate DSR (Ypage 169).
XClean the headlamps and rear lights andcheck for damage.
XClean the front and rear license plates.
XClean the wheels and tires with a water jetand remove any foreign objects.
XClean the wheels, wheel housings and thevehicle underside with a water jet; check forany foreign objects and damage.
XCheck whether twigs or other parts of plantshave become trapped. These increase therisk of fire and can damage fuel pipes, brakehoses or the air bellows of the axle jointsand propeller shafts.
XAfter the trip, examine without fail the entireundercarriage, wheels, tires, brakes, body-work structure, steering, chassis andexhaust system for damage.
XAfter driving in sand, mud, gravel, water orsimilar dirty conditions, have the followingchecked and cleaned:
Rbrake discs
Rwheels
Rbrake pads
Raxle joints
XIf you detect strong vibrations after off-roadtravel, check for foreign objects in thewheels and drive train and remove them ifnecessary. Foreign objects can disturb thebalance and cause vibrations.
Driving over poor road surfaces places greaterdemands on your vehicle than driving on nor-mal roads. After driving off-road, check thevehicle. This allows you to detect damagepromptly and reduce the risk of an accident toyourself and other road users.
Driving on sand
Observe the following rules when driving onsand:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.
RUse the left-hand steering wheel paddleshifter to shift to a lower gear appropriate tothe terrain.
