Points to remember
G
Risk of poisoning
Exhaust fumes could enter the vehicle interior
if the engine is running and the tailgate is
open. This could poison you. Therefore, you
should make sure that the tailgate is always
closed when the engine is running.
! The tailgate swings up and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and
behind the tailgate.
Do not leave the key in the luggage compart-
ment. Otherwise, you could lock yourself out.
On vehicles with a spare wheel bracket*, you
can only open the tailgate after first opening
the spare wheel bracket* completely.
i You will find details of the tailgate opening
dimensions in the Technical data section
(Y page 295). The tailgate can be:
R
opened and closed manually
(Y page 61)
R opened and closed* automatically from
outside (Y page 62)
R opened and closed* automatically from
inside (Y page 62) Spare wheel bracket*
G
Risk of accident
While the spare wheel bracket is folded to the
side, the tail lamps may be blocked from view.
Other road users may then fail to see you and
crash into your vehicle. Additionally, secure
your vehicle using a warning lamp or a warn-
ing triangle.
Do not drive with the spare wheel bracket fol-
ded out.
Make sure that the spare wheel bracket is
closed correctly.
Otherwise, the freely moving spare wheel
bracket could injure people or cause an acci-
dent.

Risk of injury
Make sure that the central area of the head
restraint supports the back of your head at
about eye level. You could seriously injure
your neck if your head is not correctly sup-
ported by the head restraint in the event of an
accident. Never travel without a correctly
adjusted and engaged head restraint.
! When you move the seats, make sure that
there are no objects in the footwell or
behind the seats. Otherwise, you could
damage the seats and the objects.
! When the rear bench seat is folded for-
wards, the front seats cannot be moved to
their rearmost position. Otherwise, you
could damage the seats and the rear bench
seat.
! Make sure that the sun visor is folded up
before setting the backrest angle and head
restraint height. Otherwise, the head
restraint and sun visor could collide when
the head restraint is fully extended.

result in severe or even fatal injuries to the
child and other occupants.
R Persons less than 1.50 m tall cannot wear
the seat belts correctly. For this reason,
secure persons less than 1.50 m tall in spe-
cially designed, suitable restraint systems.
R Children less than 1.50 m tall or under
12 years of age cannot wear the seat belts
properly. Therefore, they always should be
secured in a suitable child restraint system
on a suitable vehicle seat. You can find
more information under "Children in the
vehicle" in the "Safety" section of the Own-
er's Manual. Follow the manufacturer's
installation instructions when fitting the
child restraint system.
R Do not secure any objects with a seat belt
if the seat belt is also being used by one of
the vehicle's occupants. G
Risk of injury
If the backrest is not almost vertical, the seat
belt does not offer the intended level of pro-
tection. Under certain circumstances, this
could cause severe or even fatal injuries.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
Risk of injury
A dirty or damaged seat belt or a seat belt that
has been subjected to a load in an accident
or which has been modified no longer offers
the intended level of protection. Under certain
circumstances, this could cause severe or
even fatal injuries.
For this reason, check regularly that the seat
belts are not damaged or dirty.
Always have damaged seat belts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop. Consult a qualified specialist workshop
which has the necessary specialist knowledge
and tools to carry out the work required.
Mercedes-Benz recommends that you use a Mercedes-Benz Service Centre for this pur-
pose.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle. Fastening the belt
X
Adjust the seat and move the backrest to
an almost vertical position (Y page 64).
X Pull the belt smoothly through belt sash
guide :.
X Route the belt over the centre of the shoul-
der without twisting it.
X Engage belt tongue ;in buckle =.
Seat belt adjustment: if necessary, the driv-
er's and front-passenger seat belts auto-
matically adjust to the upper body
(Y page 77).
X If necessary, adjust the belt to the appro-
priate height (Y page 77).
X If necessary, pull upwards on the shoulder
section of the belt to tighten the belt across
your body. 76

G
Risk of accident
Do not put any objects in the driver's footwell.
If you use a floormat or carpet in the driver's
footwell, make sure that they are correctly
secured and that there is sufficient clearance
for the pedals.
Do not place several floormats on top of one
another.
Otherwise, the objects or floormats could get
between the pedals in the event of sudden
braking or acceleration. You may then no lon-
ger be able to brake, change gear or acceler-
ate as intended. This may result in an accident
and injury. G
Risk of poisoning
Never leave the engine running in enclosed
spaces. The exhaust gases contain carbon
monoxide. Inhaling exhaust fumes consti-
tutes a health hazard and could lead to loss
of consciousness or even death.

i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.
It holds the vehicle for a short time after you
have removed your foot from the brake pedal.
This gives you time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.

under any circumstances come into contact
with flammable materials such as dry grass or
petrol. The material could otherwise ignite
and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R the transmission must be in position Pand
the ignition key must be removed
R on steep uphill or downhill gradients, turn
