ground clearance MERCEDES-BENZ ML350 2006 W163 Owner's Manual

14 IntroductionOperator’s ManualWarning!
G
This Sport Utility Vehicle is designed for both on-road and off-road use. It can go places and perform tasks for which conventional 2-wheel drive
passenger cars are not intended. This vehicle will handle and maneuver differently from conventional passenger cars in driving conditions which
may occur on streets, highways and off-road use.
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with other vehicles of this type, if you
make sharp turns at excessive speeds or abrupt maneuvers, the vehicle may roll over or may go out of control and crash. Utility vehicles have a
s ig ni fi ca n tl y hi gh er ro l lo ve r r at e t h an o th er ty pe s of veh i cl es . F a il ure to o pe ra te th is v eh ic l e s a fel y ma y res ul t in a n ac c i dent, rollover of the vehicle,
and severe or fatal injury.
Before you start to drive this vehicle, read the Operator’s Manual. Take time to become familiar with the driving characteristics of this vehicle. Be
sure you are familiar with all vehicle controls. Learn how your vehicle handles on different road surfaces. Do not attempt sharp turns at excessive
speeds or abrupt maneuvers or other unsafe driving actions that can cause loss of vehicle control. When driving off-road or working the vehicle
hard, do not overload it. And, always wear your seat belts at all times. In a rollover crash, an unbelted person is significantly more likely to die than
a person wearing a seat belt.

!
Keep in mind that in rough or uneven
terrain, adjusting the vehicle to a lower
level may cause the vehicle underbody
to come in contact with the ground and
result in damage to the vehicle under-
body. Always make sure the vehicle
has sufficient ground clearance before
adjusting it to a lower level.!Before jacking up the vehicle with
equipment that lifts one or more of the
wheels completely off of the ground,
remove the SmartKey from the starter
switch.!Please also note the information in the
section on towing (
page 472).
iThe activation thresholds are defined
by the set suspension tuning
(page 249).
iThe high-speed level is not available if
towing a trailer. For more information
on towing a trailer, see “Trailer towing”
(page 314).
iFor off-road driving, please observe the
corresponding section in this manual
(page 306).

307 Operation
Driving instructions
Off-road driving rules

Engage the Off-road driving program
(page 248) before driving under
off-road conditions.


If equipped with vehicle level control*,
make sure you select a vehicle level ap-
propriate to the topographical condi-
tions. Always make sure the vehicle
has enough ground clearance.


Fasten items being carried as securely
as possible (
page 259).


Always navigate gradients with the en-
gine on and with the transmission en-
gaged in a gear. Switch on the DSR
(page 245) to help maintain a preset
speed.Checklist before off-road driving
Engine oil level


Check the engine oil level with the
control system (ML 500 only)
(page 328), or with the oil dipstick
(ML 350 only) (
page 330).
Only with a proper oil level can the
vehicle obtain a trouble-free oil supply,
even on steep gradients.
iWe recommend keeping doors, tail-
gate, windows, and tilt/sliding sun-
roof* closed whenever driving in
off-road mode.
!Observe the following during off-road
driving:

Adjust vehicle speed to condition of
terrain. The more uneven, rutty and
steeper the terrain, the lower the
speed should be.


Watch out for obstacles, such as
rocks, holes, tree stumps and ruts.


Be especially careful when driving
in unknown territory. It may be nec-
essary to get out of the vehicle and
scout the path you intend to take.


Before driving through water, deter-
mine its depth.


Do not stop vehicle while immersed
in water, and do not shut off the
engine.


In sandy soil, please drive at a
steady speed as allowed by condi-
tions. This helps overcome the vehi-
cle rolling resistance and reduces
the likelihood of the vehicle sinking
into the ground.


Do not initiate jumps with the vehi-
cle. It interrupts the forward mo-
mentum of the vehicle.


Always drive onto slopes with the
engine running and the vehicle in
gear.

311 Operation
Driving instructions


Switch off the exterior lamps as well as
the automatic climate control.


Enter the water only at a shallow spot,
driving at walking speed.


Do not stop vehicle while immersed in
water, and do not shut off the engine.
There is a very high level of driving re-
sistance in water. The surface is slip-
pery and may not be firm, making
pulling away in water difficult and dan-
gerous.


Clean mud off the tire tread after driv-
ing through water.


To dry the brakes, apply pressure to the
brake pedal several times after leaving
the water.Crossing obstacles!Never accelerate before driving into
the water. The bow wave could force
water into the engine and auxiliary
equipment, thus damaging them.
!Obstacles can damage the vehicle
underbody or suspension components.
If possible use the assistance of a sec-
ond 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 dis-
tance away from the vehicle and posi-
tioned so that he or she cannot get hurt
in case of any unexpected vehicle
movement.
After off-road driving or crossing obsta-
cles, inspect vehicle for any damage,
especially vehicle underbody and sus-
pension components. Failure to do so
can adversely affect the vehicle’s fu-
ture performance, including increased
chance of an accident.

312 OperationDriving instructionsWhen driving over tree stumps, big rocks
and other obstacles, observe the following
rules:

Make sure the Off-road driving program
(page 248) is switched on.


Avoid high engine speeds.


Select gear range1 on the automatic
transmission (
page 187).


Check the vehicle clearance before
crossing obstacles.


Cross obstacles (e.g. tree stumps or
big rocks) very slowly by aiming one of
the front wheels at the center of the ob-
stacle, and repeat same with the rear
wheel.Driving on sand


For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.


Avoid high engine speeds.


Select the gear range on the automatic
transmission that is appropriate for the
terrain.


In sandy soil, drive at a steady speed as
allowed by conditions. This helps over-
come the vehicle rolling resistance and
reduce the likelihood of the vehicle
sinking into the ground.


Drive in tracks of other vehicles if they
are not too deep and if you have suffi-
cient clearance.
Ruts
A number of off-road tracks or other by-
ways have deep ruts which can cause the
underbody to come in contact with the
ground.


Switch on the Off-road driving program
(page 248).


For vehicles with level control*, raise
the ride height (
page 250) if neces-
sary.


Avoid high engine speeds.


Select gear range1 on the automatic
transmission (
page 187).


Drive next to the ruts rather than
through them if at all possible.


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.
!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.
!Check that the ruts are not too deep
and your vehicle’s clearance is suffi-
cient. Otherwise:

your vehicle may be damaged.


the underbody of the vehicle may
come in contact with the ground
and you may get stuck.
