Observe the following notes: R
Stop the vehicle before starting to drive along
an off-road route. If necessary, select the off-
road program ( Y
page 237) or shift to the
LOW RANGE off-road gear ( Y
page 239).R
Select a vehicle level that is suitable for the
terrain. To avoid damaging the vehicle, make
sure there is always sufficient ground clear-
ance. R
Check that items of luggage and loads are
stowed safely and are well secured
( Y
page 333).R
Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR ( Y
page 236).R
Always keep the engine running and in gear
when driving on a slope. R
Adapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be. R
Do not jump with the vehicle as this will inter-
rupt the vehicle's propulsion. R
Drive 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. R
Look out for obstacles, such as rocks, holes,
tree stumps and furrows. R
Always keep the doors, the tailgate, the side
windows and the sliding sunroof closed while
the vehicle is in motion. R
Do not shift the automatic transmission to
transmission position N .R
Observe the notes on off-road fording
( Y
page 185).
i Do 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. X
Engine oil level: check the engine oil level
and add oil if necessary.
When driving on steep gradients, the engine
oil level must be sufficiently high to ensure a
correct oil supply in the vehicle. X
DEF tank (BlueTEC vehicles): check the
level and add if necessary ( Y
page 167).X
Tire-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. X
Wheels and tires: check the tire tread depth
and tire pressure. X
Check for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires. X
Replace any missing valve caps. X
Replace dented or damaged wheels. X
Rims: dented or bent rims can result in a loss
of tire pressure and damage the tire bead.
Before driving off-road, check the wheels and
replace them if necessary.
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.
Driving over rough terrain places greater
demands on your vehicle than driving on normal
roads. After driving off-road, check the vehicle.
This allows you to detect damage promptly and
reduce the risk of an accident to yourself and
other road users. X
If the Offroad or Offroad Plus drive program
is selected: select the Individual , Sport ,
Comfort or Slippery drive program
( Y
page 152). X
Deactivate the LOW RANGE off-road gear
( Y
page 239). X
Deactivate DSR ( Y
page 236).X
Lower the vehicle level again to a level suita-
ble to the road conditions, e.g. to the normal
level. X
Clean the headlamps and rear lights and
check for damage. X
Clean the front and rear license plates. X
Clean the wheels and tires with a water jet
and remove any foreign objects.188
Driving tips
Driving and parking

i When you change lanes, DISTRONIC PLUS
monitors the left lane on left-hand-drive vehi-
cles or the right lane on right-hand-drive vehi-
cles.
Stopping
G WARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if: R
there is a malfunction in the system or in
the voltage supply. R
DISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle. R
the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with. R
the battery is disconnected. R
the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is
stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever.
When the vehicle is stationary and DISTRONIC
PLUS is activated, position P is automatically
selected if: R
the driver's door is open and the driver's seat
belt is unfastened. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function. The electric parking brake secures the vehicle
automatically if DISTRONIC PLUS is activated
when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is not sufficient.
On steep uphill or downhill inclines or if there is
a malfunction, the transmission may also be
automatically shifted into position P .
Setting a speed Keep in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the speed set. X
Press the cruise control lever up C for a
higher speed or down

shown in red in the multifunction display: Low‐
ering Max. speed 12 mph (20 km/h) .
i You cannot clear these messages.
You also hear a warning. The vehicle is lowered
and offroad level 3 is canceled.
If you continue to increase your speed, the red
message continues to be shown in the multi-
function display. The newly set level is not dis-
played until the vehicle has been set to a level
suitable for the current speed.
Lowering the vehicle If you drive faster than 12 mph (20 km/h) while
the vehicle level is being lowered, you will see
the following message shown in white in the
multifunction display: Lowering Max. speed
20 km/h .
The vehicle is lowered to offroad level 2.
You will see a message in the multifunction dis-
play, for example: Lowering .
Offroad level 2 is canceled and the vehicle is
lowered to offroad level 1 if you: R
drive at speeds above 50 mph (80 km/h) or R
drive at speeds between 40 mph (64 km/h)
and 50 mph (80 km/h) for longer than
20 seconds
Offroad level 1 is canceled. Depending on the
vehicle's speed and the selected drive program,
the vehicle is automatically lowered to normal
level or low level if you: R
drive at speeds above 70 mph (112 km/h) or R
drive at speeds between 65 mph (105 km/h)
and 70 mph (112 km/h) for longer than
20 seconds
HOLD function
General notes The HOLD function can assist the driver in the
following situations: R
when pulling away, especially on steep slopes R
when maneuvering on steep slopes R
when 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. i Do 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.
Important safety notes
