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.

To avoid hazardous situations:
R make sure to check the noseweight before
each journey
R the noseweight should be as close as possible
to the maximum noseweight
R do not exceed the maximum permissible
noseweight
R the noseweight must not be lower than the
minimum permissible noseweight
Make sure that the following values are not
exceeded:
R the permissible noseweight
R the permissible trailer load
R the permissible rear axle load of the towing
vehicle
R the maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
The applicable permissible values, which must
not be exceeded, can be found:
R in your vehicle documents
R on the type plates for the trailer
R on the vehicle identification plate
If the values differ, the lowest value applies.
You will find the values approved by the manu-
facturer on the identification plates and for the
towing vehicle under "Technical data"
(Y page 256).
When reversin gthe towing vehicle, make sure
there is nobody between the trailer and the vehi- cle.
Couple and uncouple the trailer carefully. If youdo not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
When towing atrailer, your vehicle's handling
characteristics will be different from when driv-
ing without atrailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradient-
climbing capability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demands more sensitiv esteering
R has alarger turnin gcircle This can impair the vehicle's handling charac-
teristics. Adapt your driving style accordingly.
Maintain asafe distance. Drive carefully.
When towing atrailer, alway sadjust your speed
to the current road and weather conditions. Do
not exceed the maximum permissible speed for
your vehicle/trailer combination. Notes on to
wingatrailer
General notes When towing
atrailer, set the tyre pressure on
the rear axle of the towing vehicle for amaxi-
mum load. Further information on the tyre pres-
sure table in the fuel filler flap (Y page 109).
The height of the ball coupling changes with the load of the vehicle. If necessary, use atrailer
with aheight-adjustable drawbar.
You will find permissible trailer loads under
"Technical data" (Y page 256).
Driving tips X
Observe the information on ESP ®
trailer sta-
bilisation (Y page 55).
X On long and steep downhill gradients, select
shift range 1,2or 3(Y page 105) in good time.
X If necessary, shift the transfer case to LOW
RANGE (Ypage 124).
This will use the braking effect of the engine, so less braking will be required to maintain
the vehicle speed. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly. If
you need additional braking, depress the
brake pedal repeatedly rather than continu-
ously.
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginnin gthe journey, check the
trailer's documents to see what the maximum
permitted speed is. Observe the maximum per-
missible speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissibler ear axle load is increased
when towing atrailer. See the "Technical data"
section to find out whether this applies to your
vehicle (Y page 256). In the event of increased
rear axle load, the car/trailer combination may
not exceed amaximum speed of 100 km/h for
reasons concerning the operating permit. This 128
