Do not switch off the ignition while driv‐
ing. &
DANG ER Risk of death caused by
ex haust gases
Combustion engines emit poisonous exhaust
ga ses such as carbon monoxide. Inhaling
th ese exhaust gases is hazardous tohealth
and leads topoisoning. #
Never lea vethe engine or, if present,
th e auxiliary heating running in an
enclosed space wi thout suf ficient venti‐
lation. &
WARNING Risk of skidding and of an
accident due toshifting down on slippery
ro ad sur faces
If yo u shift down on slippery road sur faces to
inc rease the engine braking ef fect, the drive
wheels may lose traction. #
Do not shift down on slippery road sur‐
fa ces toinc rease the engine braking
ef fect. &
DANG ER Risk of fata l injury due topoi‐
sonous exhaust gases
If th eta ilpipe is bloc ked or suf ficient ventila‐
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter theve hi‐
cle. This is the case when theve hicle
becomes stuck in sn ow,fo rex ample. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the
engine or thest ationary heater are run‐
ning. #
Open a window on the side of theve hi‐
cle facing away from the wind toensure
an adequate supply of fresh air. &
WARNING Risk of accident due tothe
brake sy stem overheating
If yo u lea veyour foot on the brake pedal
when driving, the brake sy stem may over‐
heat.
This increases the braking dis tance and the
brake sy stem may evenfa il. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time
while driving. *

Note s on driving on salt-treated roads
The braking ef fect is limited on salt-trea ted
ro ads.
Therefore, obse rveth efo llowing no tes:
R due tosalt build-up on the brake disks and
brakepads, the braking dis tance can increase
considerab lyor result in braking only on one
side R
maintain a much greater safe dis tance tothe
ve hicle in front
To remo vesalt build-up:
R brake occasionally while paying attention to
th e tra ffic conditions
R carefully depress the brake pedal at the end
of the journey and when starting the next
journey
Note s on aquaplaning
Aq uaplaning can take place once a cer tain
amount of water has accumulated on thero ad
sur face.
Obser vethefo llowing no tes during heavy precip‐
itation or in conditions in which aquaplaning may
occur:
R reduce speed
R avoid tyre ruts
R avoid sudden steering mo vements
R brake carefully
% Also obser vethe no tes on regular lych ecking
wheels and tyres (/ page 556). Note
s on driving through water on the road
sur face
Wa ter which has entered into theve hicle can
damage the engine, electrics and transmission.
Wa ter can also enter the air intake of the engine
and cause engine damage.
Obser vethefo llowing if you must drive thro ugh
wate r:
R obser vethe maximum permissible ford ing
dep th (/ page 628)
R drive at walking pace at most, otherwise
wate r can enter theve hicle interior or engine
compartment
R vehicles tr avelling in front, or oncoming vehi‐
cles, can create waves which may exceed the
maximum permissible height of thewater
The braking ef fect of the brakes is reduced af ter
fo rd ing. Brake carefully while paying attention to
th e tra ffic conditions until braking po wer has
been fully restored. Driving and parking

Off-road driving
Re ad this section before driving your vehicle off-
ro ad. Practise bydriving over more gentle off-
ro ad terrain firs t.
R Obse rveth e no tes on the cross-country ABS
(/ page 213).
R Ifnecessa ry, select theF (/page 190)
drive program be fore driving off-road.
R Select a vehicle le vel suitable for off-road ter‐
ra in (/ page249). Toavo id damaging the
ve hicle, make sure there is alw ays suf ficient
ground clearance. R
Alw ayske ep the engine running and in gear
when driving on downhill gradients and
slopes. Obse rveth e no tes on driving in
mountainous terrain.
R Do not drive on unknown terrain that is not
easily visible and stay on mar kedro utes.
R Alw ayske ep the doors and windo wsclosed
while theve hicle is in motion.
R Deactivate Active Dis tance Assi st
DISTRONIC, cruise control and theva riable
limiter.
R Adapt your driving style to thete rrain.
R Do not use the HOLD function on steep
downhill or uphill gradients with slippery or
loose sur faces.
Driving on sand
When driving on sand, also obser vethefo llowing
instructions:
R Select theF drive prog ram.
R Select a higher vehicle le vel.
R Shift toa lo werge ar. R
Drive quickly to overcome thero lling resist‐
ance, otherwise theve hicle may dig itself in.
R Drive in the trac ksofother vehicles if possi‐
ble. Make sure that thefo llowing prerequi‐
sites are me t:
- the tyre ruts are not too deep
- the sand is firm enough
- the ground clearance is suf ficient

Driving in mountainous terrain
Also obser vethefo llowing information when
driving in moun tainous terrain:
R Obse rveth eva lues of the approach/depar‐
ture angle and of the maximum gradient
(/ page 628).

R Activate DSR be fore driving downhill, if nec‐
essary (/ page 230).
Checklist af ter driving off-road
Driving off-road places grea ter demands on your

ECO Assist can function even more precisely if
th ero ute is adhered towhen route guidance is
active. The basic function is also available with‐
out active route guidance. Notall information
and traf fic situations can be fore seen. The qual‐
ity depends on the map data.
ECO Assist is only an aid. The driver is responsi‐
ble forke eping a safe dis tance from theve hicle
in front, forve hicle speed and for braking in good time. The driver must be
ready tobrake at
all times ir respective of whe ther the sy stem
