2010 MERCEDES-BENZ ML63AMG check engine

The 4-ETS recognizes the situation and
limits the torque for the front wheels by
braking them.
Simultaneously the torque for the rear
wheels is increased.
Driving across a hilltop
Decelerate just ahead of a hilltop (do not shift
automatic transmission into neutral position
N), to prevent the vehicle from speeding up
too much after climbing a hill.
Use the momentum of the vehicle to drive
across the hilltop.
After climbing a hill, driving in this manner
prevents the vehicle from:
Rlosing ground contact when cresting hills
Rlosing its forward momentum
Rspeeding up too much after climbing the hill
Driving downhill
RDrive slowly.
RDo not drive at an angle to the incline. Steer
into the line of gravity and drive with the
front wheels pointing straight downhill.
Otherwise, the vehicle may slide sideways
off the path and roll over.
RShift automatic transmission into gear
range 1 (Y page 113).
ROn steep inclines, use the Downhill Speed
Regulation (Y page 152).
RUtilize the engine’s braking power to
reduce vehicle speed.
If this is insufficient, apply the brakes
gently. Make sure the vehicle is moving in
the line of gravity.
RCheck the brakes after a lengthy
downgrade drive.
iThe special Off-road ABS (Y page 63)
setting allows for precise and brief
(cyclical) blocking of the front wheels,
permitting them to dig into loose ground.
Remember that, when stopped, the front
wheels slide across a surface and thus lose
their ability to steer the vehicle.
Driving through water

:20 in (50 cm)
RBefore driving through water, determine its
depth.
! The water depth must not exceed the
respective value listed in the table. The
ground under the water might not be firm
which could result the water being deeper
than expected when driving the vehicle
through it. Please note that the water level
is correspondingly lower for flowing water.
RVehicles with air suspension program:
Select the highest vehicle level possible
(Y page 156).
RSwitch to off-road driving program
(Y page 155) before driving through water.
RShift automatic transmission into gear
range 1 or 2 (Y page 113).
RAvoid high engine speeds.
REnter and leave the water only at a shallow
spot, driving at walking speed.

! Never accelerate before driving into the
water. The bow wave could force water into
the engine and auxiliary equipment, thus
damaging them.
RDrive through the water slowly and at a
constant speed.
RDo not stop vehicle while immersed in
water, and do not shut off the engine.
! Do not open any of the vehicle’s doors
while driving through water. Water could
otherwise enter the vehicle interior and
damage the vehicle’s electronics, as well as
the interior equipment.
RThere is a very high level of driving
resistance in water. The surface is slippery
and may not be firm, making pulling away
in water difficult and dangerous.
RMake sure that only small bow waves are
formed when driving the vehicle through
water.
RClean mud off the tire tread after driving
through water.
RTo dry the brakes, apply pressure to the
brake pedal several times while driving
after leaving the water.
Crossing obstacles
! Obstacles can damage the vehicle
underbody or suspension components. If
possible use the assistance of a second
person outside the vehicle to scout the
path you intend to take and check for
adequate ground clearance when you cross
obstacles with your vehicle. The person
assisting you outside the vehicle should
always be a safe distance away from the
vehicle and positioned so that he or she
cannot get hurt in case of any unexpected
vehicle movement.
After off-road driving or crossing obstacles,
inspect vehicle for any damage, especially
vehicle underbody and suspension
components. Failure to do so can adversely
affect the vehicle’s future performance,
including increased chance of an accident.
When driving over tree stumps, big rocks and
other obstacles, observe the following rules:
RMake sure the off-road driving program
(Y page 155) is switched on.
RAvoid high engine speeds.
RShift automatic transmission into gear
range 1 (Y page 113).
RCheck the vehicle clearance before
crossing obstacles.
RCross obstacles (e.g. tree stumps or big
rocks) very slowly by aiming one of the front
wheels at the center of the obstacle, and
repeat same with the rear wheel.
! Special attention is needed when you
cross obstacles on a steep incline.
The vehicle could slide sideways as a result
of its possible slanted position which in turn
may result in the vehicle tipping or rolling
over.
Driving on sand
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.

When driving on sand, observe the following
rules:
R Vehicles with air suspension program:
Set the raised level ( Y page 156).
R Avoid high engine speeds.
R Shift automatic transmission into a gear
range that is appropriate for the terrain.
R In sandy soil, drive at a steady speed as
conditions permit. This helps overcome the
vehicle rolling resistance and reduce the
likelihood of the vehicle sinking into the
ground.
R Drive in tracks of other vehicles if they are
not too deep and you have sufficient
clearance.
Ruts
A number of off-road tracks or other byways
have deep ruts which can cause the
underbody to come in contact with the
ground.
R Make sure the off-road driving program
( Y page 155) is switched on.
R Vehicles with air suspension program:
Set the raised level ( Y page 156).
! Check that the ruts are not too deep and
your vehicle’s clearance is sufficient.
Otherwise:
R your vehicle may be damaged
R the underbody of the vehicle may come
in contact with the ground and you may
get stuck
R Avoid high engine speeds.
R Shift automatic transmission into gear
range 1 (Y page 113).
R Drive next to the ruts rather than through
them if at all possible.
R If the ruts are too deep to drive in, drive with
one side of the vehicle on the grassy center
strip if the route permits.
Returning from off-road driving GWarning!
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to the
nearest authorized Mercedes-Benz Center or
tire dealer for repairs.
Off-road driving increases strain on the
vehicle.
We recommend that you inspect the vehicle
for possible damage after each off-road trip.
Recognizing any damage and a subsequent
timely repair reduces the chance of a possible
breakdown or accident later on.
Proceed as follows:
R Switch off the off-road driving program
( Y page 155).
R Switch off the DSR ( Y page 153).
R Vehicles with air suspension program:
Lower the vehicle back to a level suitable
for road conditions, e.g. highway/high-
speed level ( Y page 156).
R Clean all exterior lamps and check for
possible damage.
R Clean the front and rear license plate.
R Remove excessive dirt from tires, wheels,
wheel housings, and underbody.
For instance, after driving in mud, clean the
radiator, chassis, engine, brakes, and
wheels from extreme dirt using a strong jet
of water.
R Check tires for possible damage.
R Inspect vehicle underbody, oil pan, brake
hoses, etc., as well as vehicle underbody
for possible damage.

The lowest value listed must be selected
when determining how the vehicle and
trailer are loaded.
R The tongue weight at the hitch ball must be
added to the rear axle weight to prevent
exceeding the rear Gross Axle Weight
Rating (GAWR). The GAWR is indicated on
the certification label located on the
driver’s door B-pillar ( Y page 227).
i Mercedes-Benz recommends loading the
trailer in such a manner that it has a tongue
weight between 8 % and 15 % of the GTW.
i The weight of other accessories,
passengers and cargo will reduce the
maximum trailer weight and tongue weight
your vehicle can tow.
Checking weights of vehicle and trailer
R To assure that the towing vehicle and trailer
are in compliance with the maximum
permissible weight limits, have the loaded
rig (towing vehicle including driver,
passengers and cargo, trailer fully loaded)
weighed on a commercial scale.
R Check the vehicle’s front and rear gross
axle weight, the Gross Trailer Weight (GTW)
and tongue weight.
The values as measured must not exceed
the weight limits listed under “Vehicle and
trailer weights and ratings” ( Y page 254).
Coupling a trailer GWarning!
Vehicles with air suspension program: While
you are coupling or decoupling a trailer, make
sure nobody locks or unlocks the vehicle and/
or opens or closes doors or the tailgate.
The vehicle’s level could change and you
could endanger yourself and/or others as a
result.
Make sure that you do not operate the ADS
switch or the vehicle level control system
when coupling/decoupling the trailer.
Observe maximum permitted trailer
dimensions (width and length).
Most states and all Canadian provinces
require
R safety chains between the towing vehicle
and the trailer
The chains should be criss-crossed under
the trailer tongue. They must be attached
to the hitch receiver, and not to the
vehicle’s bumper or axle.
Make sure to leave enough slack in the
chains to permit turning corners.
R a separate brake system at various trailer
weights
R a break-away switch on trailers with a
separate brake system.
Check with your local state laws for specific
requirements.
The switch activates the trailer brakes in
the possible event that the trailer might
separate from the tow vehicle.
! Do not connect a trailer brake system (if
trailer is so equipped) directly to the
vehicle’s hydraulic brake system, as your
vehicle is equipped with antilock brakes. If
you do, neither the vehicle’s brakes nor the
trailer’s brakes will function properly.

iVehicles with vehicle level control:
When you are towing a trailer, the vehicle
level always remains in the highway setting.
The following applies additionally when
towing a trailer:
R The vehicle is lowered to the highway
level when it reaches a speed of 5 mph
(8 km/h) if not set to highway level.
R The highspeed level is not available.
The restrictions that apply to towing also
apply when using accessories that are
connected to the trailer power socket, such
as a bicycle rack.
Towing a trailer
There are many different laws, including
speed limit restrictions, having to do with
trailer towing. Make sure your rig will be legal,
not only for where you reside, but also for
where you will be driving. A good source for
this information can be the police or local
authorities.
Note the following, when driving with a trailer:
R In order to gain skill and an understanding
of the vehicle’s behavior, you should
practice turning, stopping and backing up
in an area which is free of traffic.
R Before you start driving check the
- trailer hitch
- break-away switch
- safety chains
- electrical connections
- lighting
- tires
R Adjust the mirrors ( Y page 89) to permit
unobstructed view beyond rear of trailer.
R If the trailer has electric brakes, start your
vehicle and trailer moving slowly, and then
apply only the trailer brake controller by
hand to make sure the brakes are working
properly.
R Always secure items in the trailer to
prevent load shifts while driving.
R When towing a trailer, check occasionally
to make sure the load is secure, and that
trailer lighting and brakes (if so equipped)
are functioning properly.
R Take into consideration that when towing a
trailer, the handling characteristics are
different and less stable from those when
operating the vehicle without a trailer.
It is important to avoid sudden maneuvers.
R The vehicle and trailer combination is
heavier, and therefore limited in
acceleration and climbing ability, and has a
larger braking distance.
It is more prone to reacting to cross wind
gusts, and requires more sensitive steering
input.
R If possible, do not brake abruptly, but
rather engage the brake slightly at first to
permit the trailer to activate its brake. Then
increase the braking force.
! If the trailer should begin to sway, reduce
the vehicle’s speed immediately.
Do not attempt to straighten out the tow
vehicle and trailer by increasing the speed.
R If the transmission shifts between gears on
inclines repeatedly, shift to a lower gear
range manually ( Y page 113). Select 4, 3 ,
2 or 1.
A lower gear and reduction of speed
reduces the chance of engine overloading
and/or overheating.
R On very steep inclines, not manageable
with automatic transmission in gear range
1 , switch on off-road driving program
( Y page 155).
R When going down an incline, shift into a
lower gear and use the engine’s braking
effect.256Driving instructionsOperation

Resetting the maintenance service
indicator
In the event that the maintenance service on
your vehicle is not carried out at an authorized
Mercedes-Benz Center, you can have the
maintenance service indicator reset.
The automotive maintenance facility carrying
out the maintenance service will find the
information for resetting the maintenance
service indicator in the maintenance-relevant
literature for your vehicle.
Such literature is available at any authorized
Mercedes-Benz Center or directly from
Mercedes-Benz.
! If the maintenance service indicator was
reset inadvertently, have an authorized
Mercedes-Benz Center correct it.
Only reset the maintenance service
indicator if the proper maintenance service
has been performed. Not following the
proper maintenance service as described
in the Maintenance Booklet will result in
engine damage and/or other vehicle
damage not covered by the Mercedes-Benz
Limited Warranty.
Vehicle care
Cleaning and care of the vehicle
Notes
Regular and proper care will help to maintain
the value of your vehicle.
GWarning!
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the
particular container. Always open your
vehicle’s doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock away cleaning products and keep
them out of reach of children.
! When cleaning the vehicle, do not use
scouring agents. Never apply strong force
and only use a soft, wet cloth or sponge.
Otherwise you may scratch or damage the
surface to be cleaned.
While in operation, even while parked, your
vehicle is subjected to varying external
influences which, if gone unchecked, can
attack the paintwork as well as the vehicle
underbody and cause lasting damage.
Such damage is caused not only by extreme
and varying climatic conditions, but also by:
R Air pollution
R Road salt
R Tar
R Gravel and stone chipping
To avoid paint damage, you should
immediately remove:
R Grease and oil
R Fuel
R Coolant
R Brake fluid
R Bird droppings
R Insects
R Tree resins etc.
Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above
adverse influences.260Vehicle careOperation
