Event data recorders
USA only:
This vehicle is equipped with an event datarecorder (EDR). This vehicle is equipped withan event data recorder (EDR). The main pur-pose of an EDR is to record, in certain crash ornear crash-like situations, such as an air bagdeployment or hitting a road obstacle, datathat will assist in understanding how a vehi-cle's systems performed. The EDR is designedto record data relating to vehicle dynamicsand safety systems for a short period of time,typically 30 seconds or less.
The EDR in this vehicle is designed to recordsuch data as:
RHow various systems in your vehicle wereoperating
RWhether or not the driver and passengersafety belts were buckled/fastened
RHow far (if at all) the driver was depressingthe accelerator and/or brake pedal; and,
RHow fast the vehicle was traveling
These data can help provide a better under-standing of the circumstances in whichcrashes and injuries occur. NOTE: EDR dataare recorded by your vehicle only if a non-triv-ial crash situation occurs; no data are recor-ded by the EDR under normal driving condi-tions and no personal data (e.g. name, gender,age and crash location) are recorded. How-ever, other parties, such as law enforcementcould combine the EDR data with the type ofpersonally identifying data routinely acquiredduring a crash investigation.
Access to the vehicle and/or the EDR is nee-ded to read data that is recorded by an EDR,and special equipment is required. In additionto the vehicle manufacturer, other parties thathave the special equipment, such as lawenforcement, can read the information byaccessing the vehicle or the EDR.
EDR data may be used in civil and criminalmatters as a tool in accident reconstruction,accident claims and vehicle safety. Since theCrash Data Retrieval CDR tool that is used toextract data from the EDR is commercially

Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident is greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.
Emission control
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.
These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular,work relevant to safety or on safety-relatedsystems must be carried out at a qualified spe-cialist workshop.
The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out atregular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.
ECO display
The ECO display shows you how economicalyour driving style is. The ECO display assistsyou in achieving the most economical drivingstyle for the selected settings and prevailingconditions. Your driving style can significantlyinfluence the vehicle's consumption.
CAcceleration
DCoasting

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.

154Driving tips
Driving and parking

RDrive quickly to overcome the rolling resist-ance. Otherwise the vehicle's wheels couldbecome stuck in loose ground.
RDrive in the tracks of other vehicles if possi-ble. Make sure that:
-the tire ruts are not too deep.
-the sand is sufficiently firm.
-the ground clearance of the vehicle is suf-ficient.
Tire ruts and gravel roads
!Check that the ruts are not too deep andthat your vehicle has sufficient clearance.Otherwise, your vehicle could be damagedor bottom out and get stuck.
Observe the following rules when driving alongruts in off-road terrain or on roads with loosegravel:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.
RShift to a lower gear using the left-handsteering wheel paddle shifter.
RDrive slowly.
RWhere ruts are too deep, drive with thewheels of one side on the center grassyarea, if possible.
Traveling uphill
Approach/departure angle
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.
RObserve the warnings for off-road driving(Ypage 153).
RFollow the line of fall when driving on slopesand steep inclines.
RBefore driving on extreme uphill and down-hill gradients, select the off-road program(Ypage 132).
RDrive slowly.
RAccelerate gently and make sure that thewheels are gripping.
RAvoid high engine speeds, except when driv-ing on sandy and muddy routes with highdriving resistance.
RUse the left-hand steering wheel paddleshifter to shift to a lower gear appropriate tothe gradient.
RUse the left-hand steering wheel paddleshifter to shift into a lower gear in good timeon long and steep downhill gradients.
Hill start assist will aid you when pulling awayon a hill. For further information about hillstart assist, see (Ypage 128).
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.
Always observe the approach/departure anglevalues (Ypage 340).
Maximum gradient-climbing capability
Always observe the maximum gradient climb-ing ability values (Ypage 340).
Hilltops
When driving up an uphill gradient, slightlyreduce pressure on the accelerator immedi-ately before reaching the brow of the hill.Make use of the vehicle's own impetus totravel over the brow.
This style of driving prevents:
Rthe vehicle from lifting off the ground on thebrow of a hill
Rthe vehicle from traveling too quickly downthe other side
Driving downhill
RDrive slowly.
RDo not drive at an angle down steepinclines. Steer into the line of fall and drivewith the front wheels aligned straight. Oth-erwise, the vehicle could slip sideways, tipand rollover.
RShift to a lower gear using the left-handsteering wheel paddle shifter before tacklingsteep downhill gradients.
