In the event of an accident, haveadamaged
cargo compartment floor or loading area ,the
cargo tie-down rings and the tie down checked
at as pecialist workshop. Otherwise ,the load
may not be correctly secured the next time any-
thing is stowed.
Even if you follow all loading guidelines, the load
increases the risk of injury in the event of an
accident. Observe the information in the "Secur- ing aload "(
Ypage 234) and "Loa ddistribution"
(Ypage 233) sections.
You wil lfind information abou tthe maximum
roof load and maximum tailgate load in the
"Cargo tie-down points and carrier systems"
section (
Ypage 304). You wil lfind information
abou troof carriers under "Carrier systems"
(
Ypage 238).
Before loading
!
The anti-slip mats cannot be used for secur-
ing goods and must be replaced when they
show signs of:
RPermanent deformatio nand crushing
RCrack formation
RCuts
XTire pressure: check the tire pressure and
correct if necessary (Ypage 270).
XCargo compartment floor: clean the cargo
compartment floor.
The cargo compartment floor must be free
from oil and dust, dry and swept clean to pre-
vent the load from slipping.
XPlace non-slip mats (anti-slip mats) on the
cargo compartment floor if necessary.
During loading
XObserve the gross axle weight rating and per-
missible gross vehicle weight for you rvehicle.
Take into account that you rvehicle's curb
weight is increased if accessorie soroptional equipment are installed. The maximum pay-
load is thus reduced.
XObserve the notes on load distribution
(Ypage 233).
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.
XObserve the legalr equirements of the country
in which you are currently driving.
Checks after loading
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tail-
gate/rear door is open when the engine is
running, particularly if the vehicle is moving,
exhaust fumes could enter the passenger
compartment. There is arisk of poisoning.
Turn off the engine before opening the tail-
gate/rear door. Never drive off with the tail-
gate/rear door open.
XSecuring luggage/loads: make sure that
the luggage and/or load is secure before
every journey and at regular intervals during a
long journey, and correct it if necessary.
XDoors/tailgate: close the sliding doors and
tailgate/door.
XTire pressure: adjust the tire pressure
according to the vehicle load (Ypage 270).
XDrivin gstyle: adapt you rdriving style
according to the vehicle load.
Load distribution
General notes
!
Excessive load sonindividual points of the
cargo floor or on the load surface impair vehi-
cle handling characteristics and could cause
damage to the floor covering.
The overal lcenter of gravity of the load should
always be as low as possible, centered and
betwee nthe axles near the rear axle.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print.Country-specific variation sare possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to system sand function srelevantt o

Engine compartment
Hood
Important safetyn otes
GWARNING
If the hood is unlatched, it may open up when the vehicle is in motion and block your view.
There is arisk of an accident.
Never unlatc hthe hood while driving. Before
every trip, ensure that the hood is locked.
GWARNING
Openin gthe hood when the engin eisover-
heated or when ther eisafire in the engine
compartmen tcould expose you to hot gases
or other servicep roducts. There isarisk of
injury.
Let an overheated engin ecool down before
openin gthe hood. If ther eisafire in the
engin ecompartment, keep the hood closed
and contact the fire department.
GWARNING
The engin ecompartmen tcontains moving
components. Certain components, such as
the radiator fan, may continue to run or start
again suddenly when the ignition is off. There is ar isk of injury.
If you need to do any work inside the engine
compartment:
Rswitc hoff the ignition
Rneve rreach int othe area where ther eisa
risk of danger from movingc omponents,
such as the fan rotation area
Rremovej ewelry and watches
Rkeep items of clothing and hair, for exam-
ple, away from movingp arts
GWARNING
The ignition system operate swithahigh volt-
age. If you touc hthe live components, you
could receiv eanelectric shock.T here is an
increased risk of injury.
Never touc hcomponents of the ignition sys-
tem if:
Rthe engin eisrunning or being started
Rthe key is in radio position or drive position
in the ignition lock
The live components of the ignition system are,
for example:
Rignition coils
Rspark plug connectors
Rdiagnostic sockets
GWARNING
Certain components in the engin ecompart-
ment ,such as the engine, radiator and parts
of the exhaust system ,can becomev ery hot.
Working in the engin ecompartmen tposes a
risk of injury.
Where possible, let the engin ecool down and
touc honly the components described in the
following.
If you have to carry out work in the engin ecom-
partment ,only touc hthe following components:

Let an overheated engine cool down before
opening the hood. If there is afire in the
engine compartment, keep the hood closed
and contact the fire department.
GWARNING
Certain components in the engine compart-
ment,s uch as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
!Do not use your hands to push the hood
down. You could damage it otherwise.
XHold support strut ?and lift the hood
slightly.
XGuide support strut ?towards retainer =
and apply slight pressure to make it engage.
XLower the hood and allow it to fall with
momentum from aheight of approximately
1ft( 30 cm).
The hood locks audibly.
XCheck that the hood is correctly locked.
If the hood can be raised slightly, it is not
properly engaged. If the hood is not correctly
engaged, open the hood again. Let the hood
fall with alittle more momentum.

GWARNING
The brake flui dconstantly absorbs moisture
from the air. This lowers the boiling point of
the brake fluid. If the boiling point of the brake
flui dist oo low ,vapo rpockets may form in the
brake system when the brakes are applied
hard .This would impair braking efficiency.
There is arisk of an accident.
You should have the brake flui drenewe dat
the specified intervals.
!If the brake flui dlevelint he brake flui dres-
ervoir has fallen to the MIN mark or below,
check the brake system immediatel yfor
leaks. Also check the thickness of the brake
linings. Visi taqualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
!Brake flui dcorrodes paint, plastic and rub-
ber. If paint, plastic or rubber has come into
contact with brake fluid, rinse with water
immediately.
Have the brake flui drenewe devery 2years at a
