Problems with the seat heating Problem
Possible causes/consequences and P Solutions
The seat heating has
switched off prema-
turely or cannot be
switched on. The on-board voltage is too low because too many electrical con-
sumers are switched on. X
Switch off electrical consumers that you do not need, such as
the rear window defroster or interior lighting.
Once the battery is sufficiently charged, the seat heating will
switch back on automatically.
Switching the seat ventilation on/off
Switching on/off
The three blue indicator lamps in the buttons
indicate the ventilation level you have selec-
ted. X
Turn the SmartKey to position 2 in the igni-
tion lock ( Y
page 165).X
To switch on: press button C repeatedly
until the desired ventilation level is set. X
To switch off: press button C repeatedly
until all the indicator lamps go out.
i If the battery voltage is too low, the seat
ventilation may switch off.
i You can open the side windows and the
sliding sunroof using the "Convenience
opening" feature ( Y
page 99). The seat ven-
tilation of the driver's seat automatically
switches to the highest level.120

If you drive th e vehicle faste r than 10 mph
(16 km/h), th e Check

If th e Refill DEF No Start in XXX X km
message is shown in th e multifunction dis -
play, you can still drive th e vehicle over th e
distanc e shown . If DE F is no t refilled , you will
subsequently be unable to star t th e engine .
If th e Refill DEF Eng . Start Not Poss.
message appears in th e multifunction display
and th e engin e doe s no t start , you mus t add
DEF. X
Ad d at leas t 1 gal (3.8 l) of DEF.X
Switch on the ignition for at least 60 sec-
onds. X
Start the engine.
i Have the DEF tank refilled at a qualified
specialist workshop.
Use the special DEF refill bottle when adding
DEF between maintenance intervals. Contact
an authorized Mercedes-Benz Center with
any questions or, if necessary, contact Road-
side Assistance ( Y
page 26). If the outside temperature is below 12 ‡
(

water. Seek medical assistance without
delay. R
Change out of clothing contaminated with
DEF immediately.
! Only use DEF in accordance with
ISO 22241. Do not mix any additives with
DEF, and do not dilute DEF with water. This
may destroy the BlueTEC exhaust gas after-
treatment system.
! The vehicle must be parked on level
ground to fill the DEF tank. The DEF tank
can only be filled as intended with the vehi-
cle parked on a level surface. This avoids
false level readings. Filling the tank is not
permitted if the vehicle is not parked on a
level surface. There is a danger of overfill-
ing, which could result in damage to com-
ponents of the BlueTEC exhaust gas after-
treatment.
! Rinse surfaces that have come into con-
tact with DEF immediately with water or
remove DEF using a damp cloth and cold
water. If the DEF has already crystallized,
use a sponge and cold water to clean it. DEF
residues crystallize after time and contam-
inate the affected surfaces.
! DEF is not a fuel additive and must not be
added to the fuel tank. If DEF is added to
the fuel tank, this can lead to engine dam-
age.
For further information on DEF, see
( Y
page 450).
Opening the DEF filler cap The fuel filler flap is unlocked or locked auto-
matically when you open or close the vehicle
with the SmartKey or with KEYLESS-GO. X
Switch the ignition off. X
Press the fuel filler flap in the direction of
arrow C .
The fuel filler flap swings up. X
Turn blue DEF fuel filler cap D counter-
clockwise and remove it.
DEF filler cap D is secured with a plastic
strip.
DEF refill canisters
! Do not tighten the disposable hose with
too much force. The disposable hose may
otherwise be destroyed.
X
Unscrew the cap from the opening on top of
DEF refill canister D . X
Place disposable hose C on the opening of
DEF refill canister D and screw it on clock-
wise until hand-tight. Refueling 187
Driving and parking Z

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 186).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 nor-
mal 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
Vehicles with the ON&OFFROAD pack-
age: activate the on-road program
( Y
page 258). X
Deactivate the LOW RANGE off-road gear
( Y
page 259). X
Deactivate DSR ( Y
page 257).X
Lower the vehicle level again to a level suit-
able to the road conditions, e.g. to the high-
way 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. X
Clean the wheels, wheel housings and the
vehicle underside with a water jet; check
for any foreign objects and damage. X
Check whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber bel-
lows of the axle joints and propeller shafts. X
After the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage. X
After driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned. X
If you detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
Driving on sand
Observe the following rules when driving on
sand: R
Vehicles with the ON&OFFROAD pack-
age: select off-road program 1
( Y
page 258). R
Select a higher vehicle level. R
Avoid high engine speeds. R
Use the left-hand steering wheel paddle
shifter to shift to a lower gear appropriate
to the terrain.200
