RefuellingDriving and parking

To ensure that the vehicle is safeguarded
against rolling away unintentionally:
R the parking brake must be applied
R the transmission must be in position Pand the
key must be removed from the ignition lock
R the transfer case must not be in the neutral
position
R on uphill or downhill gradients, turn the front
wheels towards the kerb
R the empty vehicle must be secured at the
front axle with awheel chock or similar
object ,for example, on uphill or downhill gra-
dients
R al aden vehicle must also be secured at the
rear axle with awheel chock or similar object,
for example, on uphill or downhill gradients Switching off the engine

WARNING
The automatic transmission switches to neu-
tral position Nwhen you switch off the engine.
The vehicle may roll away. There is arisk of an
accident.
After switching off the engine, alwayss witch
to parking position P.Prevent the parked vehi-
cle from rolling awaybya pplying the parking
brake.
X Shift the automatic transmission to position
P.
X Turn the key to position 0in the ignitionlock

matic transmission only automatically shifts into neutral
Nwhe nyou switc hoff the engine
using the key. Parking brake
G
WARNING
If you mus tbrake the vehicl ewith the parking
brake, the braking distance is considerably
longer and the wheels coul dlock. This increa-
ses the risk of skidding and an accident.
Only use the parking brake to brake the vehi- cle when the service brake is faulty. Do not
apply the parking brake too firmly .Ifthe
wheels lock, release the parking brake until
the wheels begi nturning again. G
WARNING
If you leave children unattended in the vehi-
cle, they may be abletos et the vehiclein
motion if, for example, they:
R release the parking brake
R shift the automatic transmission out of park
position P
R start the engine
In addition, they may operate vehicl eequip-
ment and become trapped. There is arisk of
an accident and injury.
When leaving the vehicle, alwayst ake the key
with you and lock the vehicle. Never leave
children unattended in the vehicle. The brake light
sdonot light up when you brake

WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available wit
hlimitations, or not at all. This could affect,
for example, th epower steerin gand th ebrake
boosting effect .You will requir econsiderably
mor eeffort to steer and brake. Ther eisarisk
of an accident.
Do not switch off th eignitio nwhile driving.
Drive sensibly –savef uel Observe the following tips to save fuel:
X The tyre sshould always be inflated to the rec-
ommended tyre pressure.
X Remove unnecessary loads.
X Remove roof carriers when they are not nee-
ded.
X Warm up the engine at low engine speeds.
X Avoid frequent acceleration or braking.
X Have all service and maintenance work car-
ried out at the specified intervals.
Fuel consumption also increases when driving in
cold weather, in stop-start traffic, on short jour- neys and in hilly terrain. Short journeys
! Vehicles with
adiesel particle filter: if the
vehicle is mostly driven for short distances, it
is possible that malfunction smay occur dur-
ing the automatic cleaning of the diesel par-
ticle filter. This may lead to fuel collecting in
the engine oil and cause engine failure. There- fore, if you frequently drive short distances,
you should take a20minute trip on amotor-
way or rural road at least every 500km. Brakes
Imp ortant safety notes G
WARNING
If you shift dow nonaslippery road surface in
an attempt to increas ethe engine's braking
effect, the drive wheels coul dlose their grip.
This increases the risk of skidding and having
an accident.

WARNING
When leavin gthe vehicle, it can still roll away
despite being braked by the HOLD function if:
R there is amalfunction in the system or in
the voltag esupply
R the HOLD function is deactivated by the
accelerator peda lbeing depressed, e.g. by
av ehicl eoccupant
R the electrica lsystem in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is arisk of an accident.
Before leaving the vehicle, alwaysd eactivate
the HOLD function and secure the vehicle
from rolling away.
Deactivating the HOLD function (Y page123).
Activation conditions You can activate the HOLD fun
ction if:
R the vehicle is stationary
R the engin eisrunning or if it has been auto-
matically switched off by the ECO start/stop
function
R the driver's door is close dorifyour seat belt
is fastened
R the parking brak eisreleased
R the transmission is in position D,Ror N
Activating th eHOLD function X
Make sure that the activation condition sare
met.
X Depress the brake pedal.
X Quickly depress the brake pedal further until
ë appears in the multifunction display.
The HOLD function is activated. You can
release the brake pedal.
If depressing the brake pedal the first time does not activate the HOLD function, wait briefly and
then try again. Deactivating the HOLD function The HOLD function is deactivated automatically
if:
R you depress the accelerator and the trans-
mission is in position Dor R.
R the transmission is in position j.
R you depress the brake pedal again with acer-
tain amount of pressure until ëdisap-
pears from the multifunction display.
On steep uphill or downhill inclines or if there is
am alfunction, the transmission may also be
automatically shifted into position P. Permanent all-wheel drive
! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
! When testin
gthe parking brake, operate the
vehicle only briefly (for amaximum of ten sec-
onds) on abrake test dynamometer. When
doing this, turn the key to position 0or 1in
the ignition. Failure to do this can cause dam- age to the drive train or the brake system.
! Af
unction or performanc etest should only
be carried out on atwin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult aqualified
workshop. You could otherwise damage the
drive train or the brake system.
The all-wheel drive system ensures that all four
wheels are permanently driven. The all-wheel
drive system improves vehicle traction together with ESP ®
and 4ETS if adrive wheel spins due to
insufficient grip.
Only when you use winter tyres (M+S tyres) in
wintry driving condition sand, if necessary, snow
chains (Y page 237). Only in this way can the
maximum effect of all-wheel drive be achieved.
