Protecting the environment
General notes
HEnvironmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
that form the basis of our existence on this
planet to be used sparingly and in amanner
that takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tire wear are affected by these factors:
Roperating conditionsofy our vehicle
Ryour personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
Ravoid short trips as these increase fuel con-
sumption.
Ralways make sure that the tire pressures
are correct.
Rdo not carry any unnecessary weight.
Rremove roof racks once you no longer need
them.
Rar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
Ralways have service work carried out at a
qualified specialist workshop.
Personal driving style:
Rdo not depress the accelerator pedal when
startin gthe engine.
Rdo not warm up the engine when the vehicle
is stationary.
Rdrive carefully and maintain asafe distance
from the vehicle in front.
Ravoid frequent, sudden acceleration and
braking.
Rchange gear in good time and use each gear
only up to Ôof its maximum engine speed.
Rswitch off the engine in stationary traffic.
Rkeep an eye on the vehicle's fuel consump-
tion.
Environmental concerns and recom-
mendations
Wherever the Operator's Manual requires you to
dispose of materials, first try to regenerate or re-
use them. Observe the relevant environmental
rules and regulations when disposing of materi-
als. In this way you will help to protect the envi-
ronment.
Genuine Mercedes-Benz parts
HEnvironmental note
Daimler AG also suppliesr econditioned major
assemblies and parts which are of the same
quality as new parts. They are covered by the
same Limited Warranty entitlements as new

Introduction

SportsUtility Vehicle
GWARNING
Due to the high center of gravity, the vehicle
may start to skid and roll over in the event of
an abrupt steering maneuver and/or when
the vehicle's speed is not adapted to the road
conditions. There is arisk of an accident.
Always adapt your speed and driving style to
the vehicle's driving characteristics and to the
prevailing road and weather conditions.
Utility vehicles have asignificantly higher roll-
over rate than other types of vehicles.
Failure to operate this vehicle safely may result
in an accident, rollover of the vehicle, and severe
or fatal injury.
In ar ollover crash, an unbelted person is signif-
icantly more likely to die than aperson wearing
as eat belt.
You and all vehicle occupants should always
wear your seat belts.
Operating safety
Important safety notes
GWARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunction sor
system failures. There is arisk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at aqualified specialist workshop.
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 arisk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly.I n
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
GWARNING
Modifications to electronic components, their software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at aqualified
specialist workshop.
!There is arisk of damage to the vehicle if:
Rthe vehicle becomes stuck ,e.g. on ahigh
curb or an unpaved road
Ryou drive too fast over an obstacle, e.g. a
curb, aspeed bump or apothole in the road
Rah eavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged 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 are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at aqualified spe-
cialist workshop. If on continuing your jour-
ney you notic ethat driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult aqualified spe-
cialist workshop.

Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchloratem aterial,
which may require special handlin gand regard
for the environment. National guideline smust
be observed duringd isposal. In California, see
www.dtsc.ca.gov/HazardousWaste/

Method of operation
Duringthe firsts tageofac ollision, the restraint
system control unit evaluate simportan tphysi-
cal data relating to vehicle deceleratio noraccel-
eration, such as:
Rduration
Rdirection
Rintensity
Based on the evaluatio nofthis data, the
restraint system control unit triggers the Emer-
genc yTensionin gDevices duringaf rontal or
rear collision.
An Emergency Tensionin gDevice can only be
triggered, if:
Rthe ignition is switched on
Rthe component softhe restraint system are
operational. You can findf urther information
under :"Restraint system warnin glamp"
(
Ypage 38)
Rthe seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensionin gDevices in the rear
compartmenta re triggeredindependently of the
lock status of the seat belts.
If the restraint system control unit detect sa
more severea ccident,further component sof
the restraint system are activate dindepend-
ently of each other in certain frontal collision
situations:
RDriver'sa ir bag
RFront-passenge rfront air bag
The front-passenge rfront air bag is activate dor
deactivate ddepending on the personont he
front-passenge rseat. The front-passenge rfront
air bag can only deploy in an accident if the
PASSENGER AI RBAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR
BA GO FF indicator lamp (
Ypage 39).
Your vehicle has atwo-stag edriver's air bag.
Durin gthe firstd eployments tagethe driver's air
bag fills with sufficient propellantg as to reducet
he risk of injuries. The front air bag is fully
deployed with the maximum amount of propel-
lant gas if asecond deploymentt hreshold is
reached within afew milliseconds.
The activatio nthreshold of the Emergency Ten-
sioning Devices and the air bag are determined
by evaluatin gthe rate of vehicle deceleratio nor
acceleration which occurs at various point sin
the vehicle. This process is pre-emptive in
nature. Deployment should tak eplace in good
tim eatt he star tofthe collision.
The rate of vehicle deceleratio noracceleration
and the direction of the force are essentially
determined by:
Rthe distribution of forces duringt he collision
Rthe collision angle
Rthe deformationcharacteristics of the vehicle
Rthe characteristics of the object with which
the vehicle has collided
Factor swhich can only be seen and measured
after acollision has occurred do not play adeci-
sive role in the deploymentofana ir bag. Nor do
the yprovide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with-
out an air bag being deployed. This is the case if
only partsw hich are relatively easily deformed
are affected and the rate of deceleratio nisnot
high. Conversely, air bags may be deployed even
though the vehicle suffers only minor deforma-
tion .This is the case if, for example, very rigid
vehicle partss uch as longitudinal body mem-
bers are hit, and sufficient deceleratio noccurs
as aresult.
If the restraint system control unit detect saside
impact or if the vehicle rolls over,t he applicable
component softhe restraint system are activa-
ted independently of each other depending on
the apparentt ype of accident .

Drive on carefully. Hav eABS checke dimme-
diately at aqualified specialist workshop.
When AB Sismalfunctioning ,other systems ,
includin gdriving safet ysystems ,will also
become inoperative. Observ ethe information

Braking
XIf ABS intervenes: continue to depress th e
brak epedal vigorously until th ebraking sit -
uation is over.
XTo make afullb rake application: depress
th eb rak epedal wit hfull force .
If AB Sintervenes when braking ,you will fee la
pulsing in th ebrak epedal .
The pulsating brak epedal can be an indication
of hazardous road conditions, and function sasa
reminder to tak eextra carew hile driving .
Off-road ABS
An ESP®system specifically suited to off-road
terrain is activated automatically once th eoff-
road program is activated.
At speeds belo w37mph (60 km/h), th efront
wheels loc kcyclically during braking .The dig-
ging-in effec tachieved in th eprocess reduce s
th es topping distanc eonoff-road terrain .This
limits steering capability.
BAS (Brak eAssistS ystem)
General information
BA So perate sinemergenc ybraking situations.
If you depress th ebrak epedal quickly, BA S
automatically boosts th ebraking force ,thu s
shortening th estopping distance.
