When loading your vehicle for driving off-road or
on a construction site, keep the vehicle's centerof gravity as low as possible.
Checklist before driving off-road
XCheck the fuel and DEF levels (Ypage 161)
and top up (Ypage 128).
XEngine: check the oil level (Ypage 221) and
add oil (Ypage 223).
Before driving up or down steep gradients, fill
the oil to the maximum level.
iIf you drive up or down steep gradients, the
4 symbol may appear in the display. The
engine operating safety is not put at risk if you
have filled the engine oil to the maximum level
before the journey.
XVehicle tool kit: check that the jack is work-
ing (Ypage 241).
XMake sure that a lug wrench (Ypage 241),
wooden underlay for the jack, a robust tow
cable and a folding spade are carried in the
vehicle.
XWheels and tires: check the tire tread depth
(Ypage 249) and tire pressure
(Ypage 251).
Rules for driving off-road
!Always bear the vehicle's ground clearance
in mind and avoid obstacles, e.g. deep ruts.
Obstacles may damage the following parts of
the vehicle:
Rthe chassis
Rthe drive train
Rthe fuel and supply tanks
For this reason, you should always drive
slowly when driving off-road. If you have to
drive over obstacles, have the front
passenger direct you.
iWe recommend that you additionally carry a
shovel and a recovery rope with shackle in the
vehicle.
REnsure that loads and items of luggage are
securely stowed or lashed down
(
Ypage 213).
RBefore driving off-road, stop the vehicle and
shift to a low gear.
RIf the surface demands it, temporarily deacti-
vate ASR when pulling away (Ypage 55).
ROnly drive off-road with the engine running
and a gear engaged.
RDrive slowly and smoothly. Walking pace is
necessary in many situations.
RAvoid spinning the drive wheels.
RMake sure that the wheels always remain in
contact with the ground.
RDrive with extreme care over unknown terrain
where you can only see for a short distance.
As a precaution, get out of the vehicle to take
a look at the route to be taken in advance.
RCheck the water depth before fording.
RWatch out for obstacles (e.g. rocks, holes,
tree stumps and ruts).
RAvoid edges where the surface could crumble
or break away.
Checklist after driving off-road
!If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop.
Off-road driving places a higher demand on your
vehicle than normal road operation. Check your
vehicle after driving on rough terrain. By doing
so you will notice any damage in good time and
reduce the risk of an accident for yourself and
other road users. Clean your vehicle thoroughly
before driving on public roads.
Observe the following points after driving off-
road, on construction sites and before driving on
public roads:
XVehicles with all-wheel drive: deactivate
all-wheel drive (Ypage 147).
XActivate ASR (Ypage 55).
XClean the headlamps and tail lamps and
check them for damage.
XClean the front and rear license plates.
XClean the windshield, windows and exterior
mirrors.
XClean the steps, door sills and grab handles.
This increases safety of footing.
XClean the wheels and tires, wheel arches and
the underbody of the vehicle with a water jet.
This increases road grip, especially on wet
road surfaces.

The display switches off automatically after
approximately 30 seconds if:
Rthe key is in position0in the ignition lock.
Rthe vehicle lighting is not switched on.

matic headlamp mode.
Tachometer
!
Do not drive in the overrevving range, as this
could damage the engine.
HEnvironmental note
Avoid driving at high engine speeds. This
unnecessarily increases the fuel consumption
of your vehicle and harms the environment as
a result of increased emissions.
The red band in the tachometer indicates the
engine's overrevving range.
To protect the engine, the fuel supply is inter-
rupted when the red band is reached.
Outside temperature
You should pay special attention to road condi-
tions when temperatures are around the freez-
ing point.
On vehicles without steering wheel buttons
(
Ypage 162) and on vehicles with steering
wheel buttons (Ypage 166), the outside tem-
perature display is in the display.
Changes in the outside temperature are dis-
played after a short delay.
Speedometer
The speed can also be shown in the display. You
can find information on the digital speedometer for vehicles without steering wheel buttons
under (
Ypage 162) and for vehicles with steer-
ing wheel buttons under (Ypage 166).
iIn some countries, a warning sounds when
the vehicle reaches the maximum speed limit,
e.g. at 75 mph (120 km/h).
Trip odometer
XTo reset: make sure that the display is show-
ing the trip odometer if you have a vehicle with
steering wheel buttons (

Checking the brake fluid level
XStop your vehicle as far away from traffic as
possible on level ground.
XSwitch off the engine.
XSecure the vehicle to prevent it from rolling
away.
XOpen the hood (Ypage 219).
XCheck the brake fluid level.
The brake fluid level is correct if the level is
between the MIN mark and MAX mark on
brake fluid reservoir:.
XClose the hood.
!If the brake fluid level in the brake fluid res-
ervoir has fallen to the MIN mark or below,
check the brake system immediately for
leaks. Also check the thickness of the brake
linings. Visit a qualified specialist workshop
immediately.
Do not add brake fluid. This does not correct
the malfunction.
Washer fluid
GWARNING
Windshield washer concentrate could ignite if it comes into contact with hot engine compo-
nents or the exhaust system. There is a risk of
fire and injury.
Make sure that no windshield washer con-
centrate is spilled next to the filler neck.
!Only use washer fluid that is suitable for
plastic lamp lenses, e.g. MB SummerFit or MB WinterFit. Unsuitable washer fluid could dam-
age the plastic lenses of the headlamps.
Example: washer fluid reservoir
Add windshield washer concentrate to the
washer fluid all year round. Observe the infor-
mation on washer fluid in the "Technical data"
section (
Ypage 286).
Adding washer fluid
XMix the washer fluid to the appropriate mixing ratio in a container beforehand.
XOpen the hood (Ypage 219).
XPull cap :on the washer fluid reservoir
upwards at the tab.
XAdd the premixed washer fluid.
XPress cap :onto the filler neck until it
engages audibly.
XClose the hood.
Fuel system
Draining the fuel filter
GWARNING
Fuel is highly flammable. Improper handling of
fuel creates a risk of fire and explosion.
Avoid fire, open flames, smoking and creating
sparks under all circumstances. Switch off the
ignition and auxiliary heating before carrying
out work to the fuel system. Always wear pro-
tective gloves.
HEnvironmental note
Dispose of the water-fuel mixture in an envi-
ronmentally responsible manner.
!When the :indicator lamp lights up,
drain the fuel filter with water separator
immediately. Otherwise, the engine may be
damaged.

When handling washer fluid, observe the impor-
tant safety notes on service products
(
Ypage 278).
Mixing ratio
Add windshield washer concentrate to the
washer fluid all year round. Adapt the mixing
ratio to the ambient temperature.
At temperatures above freezing:
XFill up the washer fluid reservoir with a mix-
ture of water and windshield washer concen-
trate, e.g. Summerwash to prevent smearing.
At temperatures below freezing:
XFill up the washer fluid reservoir with a mix-
ture of water and windshield washer concen-
trate, e.g. Winterwash if there is a danger of
frost.
This prevents washer fluid from freezing on
the windshield.
