General driving tips
Important safety notes
GWARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's
concentration must always be directed pri-
marily at road traffic. For your own safety and
that of others, we recommend that you stop
the vehicle at a safe place and in accordance
with the traffic conditions before making or
accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate COMAND (Cockpit Managementand Data System) in compliance with all legal
requirements and when the road, weather and
traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance
of 44 ft (approximately 14 m)a second when
it is traveling at only 30 mph (approximately
50 km/h).
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work performed at the
service intervals specified in the Maintenance
Booklet or indicated by the service interval
indicator.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
132Driving tips
Driving and parking
The following driving systems are specially
adapted to off-road driving:
R4ETS (Ypage 57)
RTransfer case (Ypage 162)
RDifferential locks (Ypage 162)
Observe the following notes:
Rstop your vehicle and, if necessary, shift the
transfer case to LOW RANGE(Ypage 162)
before driving off-road.
Rin transfer case position LOW RANGEthe
ECO start/stop function is not available
(
Ypage 114).
Rengage the differential locks, if necessary
(Ypage 165).
iABS, 4ETS, ESP®and BAS are deactivated
while the differential locks are engaged. This
allows the front wheels to lock briefly, so that
these can dig into a loose surface. However,
please note that locked wheels skid and can
no longer steer.
RCheck that items of luggage and loads are
stowed safely and are well secured
(
Ypage 219).
RTo avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
RAlways keep the engine running and in gear
when driving on a downhill gradient.
RAlways keep the engine running and in gear
when driving on a slope.
RDrive slowly and evenly, if necessary at a
walking pace.
REnsure that the wheels are in contact with the
ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. For safety rea-
sons, get out of the vehicle first and survey
the off-road route.
RCheck the depth of water before fording rivers
and streams.
RWhen fording, do not stop and do not switch
off the engine.
RLook out for obstacles, such as rocks, holes,
tree stumps and furrows.
RAlways keep the doors, rear door, side win-
dows and the sliding sunroof closed while the
vehicle is in motion.
RSwitch off cruise control.
RDo not stray from marked routes or paths.
RAdapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be.
RDrive slowly and at an even speed through the
water. Ensure that a bow wave does not form
as you drive.
ROn sand, drive quickly to overcome the rolling resistance. Otherwise the vehicle's wheels
could become st
uck in loose ground.
RDo not jump with the vehicle as this will inter-
rupt the vehicle's propulsion.
RAvoid high engine speeds. Drive at appropri-
ate engine speeds (maximum 3,000 rpm).
RDo not shift the automatic transmission to
transmission position N.
RAlways check the vehicle for damage after off-
road driving.
iInformation about retrofitting special all-ter-
rain tires is available from any qualified spe-
cialist workshop.
iDo not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.
Checklist before driving off-road
!If the engine oil warning lamp lights up while
the vehicle is in motion, stop the vehicle in a
safe place as soon as possible. Check the
engine oil level. The engine oil warning lamp
warning must not be ignored. Continuing the
journey while the symbol is displayed could
lead to engine damage.
XOil level: check the engine oil level and add oil
if necessary.
Only then does the engine receive enough oil when the vehicle is on a steep incline.
XTire-changing tool kit: check that the jack is
working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
XWheels and tires: check the tire tread depth
and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
XReplace any missing valve caps.

HOLD function
General notes
The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
iDo not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.
Activation conditions
You can activate the HOLD function if:
Rthe vehicle is stationary
Rthe engine is running or if it has been auto-
matically switched off by the ECO start/stop
function
Rthe engine is running
Rthe driver's door is closed or your seat belt is
fastened
Rthe transmission is in position D,R or N
RDISTRONIC PLUS is deactivated
Activating the HOLD function
The vehicle's brakes are applied when the HOLD
function is activated. For this reason, deactivate
the HOLD function while in the car wash or while
towing.
XMake sure that the activation conditions are
met.
XDepress the brake pedal.
XQuickly depress the brake pedal further until
ë appears in the multifunction display.
The HOLD function is activated. You can
release the brake pedal.
iIf depressing the brake pedal the first time
does not activate the HOLD function, wait
briefly and then try again.
Deactivating the HOLD function
GWARNING
When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated automatically if:
Ryou accelerate and the transmission is in
position Dor R.
Ryou shift the transmission to position P.
Ryou depress the brake pedal again with a cer-
tain amount of pressure untilëdisap-
pears from the multifunction display.
Ryou activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if there
is a malfunction, 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 Limited 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 testing the parking brake, operate the
vehicle only briefly (for a maximum of ten sec-
onds) on a brake test dynamometer. When
doing this, turn the SmartKey to position 0or
1 in the ignition. Failure to do this can cause
damage to the drive train or the brake system.
