Driving over obstacles
!
Obstacles could damage the floor of the
vehicle or components of the chassis. Ask
passengers for guidance when driving over
large obstacles. The passenger should
always keep a safe distance from the
vehicle when doing so in order to avoid
injury as a result of unexpected vehicle
movements. After driving off-road or over
obstacles, check the vehicle for possible
damage, especially to the underbody and
the components of the chassis.
! Drive with particular care when driving
over an obstacle while driving up or down
a steep slope.
The vehicle could otherwise tilt and slide
sideways or tip over. Observe the following rules when driving over
tree stumps, large stones and other
obstacles:
R Observe the safety notes (Y page 164) and
the general notes (Y page 164) on off-road
driving.
R Shift the transfer case to LOW
RANGE( Ypage 194).
R Avoid high engine speeds.
R Restrict the shift range to 1(Ypage 150).
R Make sure that you have enough ground
clearance before driving across an
obstacle.
R Drive very slowly.
R Try to drive straight over the center of
obstacles: front wheel first, then rear
wheel. Traveling uphill
Approach/departure angle G
WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. i
Always observe the approach/departure
angle values ( Ypage 351).
R Observe the safety notes (Y page 164) and
the general notes (Y page 164) on off-road
driving.
R Do not drive at an angle on slopes, inclines
or gradients, but instead follow the direct
line of fall. Note that the climbing ability of
your vehicle depends on the terrain
conditions.
R Before driving on extreme uphill and
downhill gradients, shift the transfer case
to LOW RANGE( Ypage 194).
R Engage the differential locks, if necessary
(Y page 196).
R Drive slowly.
R Accelerate gently and make sure that the
wheels are gripping.
R Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance. Driving tips
167Driving and pa rking Z

R
Avoid high engine speeds – drive at an
appropriate engine speed (maximum
3,000 rpm).
R When driving down an incline, make use of
the engine's braking effect. Observe the
engine speed; do not overrev the engine.
i Further information on the maximum
engine speed: (Y page 206).
R Select a shift range appropriate to the
gradient.
R Before tackling steep downhill gradients,
select shift range 1(Ypage 150).
R Always check the brakes after driving off-
road.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(Y page 141).
Maximum gradient-climbing capability Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
Always observe the maximum gradient
climbing ability values (Y page 351).
Hilltops When driving on an uphill gradient, reduce
pressure slightly on the accelerator
immediately before reaching the top of the hill
(do not shift the transmission to position N).
Use the vehicle's own impetus to drive over
the top of the hill. This style of driving prevents:
R
the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from traveling too quickly down
the other side
Driving downhill R
Before tackling steep downhill gradients,
select shift range 1(Ypage 150).
This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Observe the notes on driving in
mountainous terrain (Y page 168).
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and roll over.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS setting
(Y page 61) enables repeated, brief,
precise locking of the front wheels, which
leads to the wheels digging into the loose
ground. Note that when the front wheels
are fully braked, they slide easily over the
surface of the ground, making it difficult to
steer. Driving systems
Cruise Control
Important safety notes G
WARNING
The brake pedal moves when cruise control
brakes the vehicle. A foot in the area under
the brake pedal could become trapped. The
movement of the pedal, and therefore the 168
Driving systemsDriving an
d parking

vehicle's ability to brake, may be restricted by
objects in the area under the brake. There is
a risk of an accident and injury.
Do not place your foot under the brake pedal.
Keep the area under the brake pedal free from
obstructions.
If you fail to adapt your driving style, cruise
control can neither reduce the risk of
accident nor override the laws of physics.
Cruise control cannot take account of road,
weather and traffic conditions. Cruise control
is only an aid. You are responsible for the
distance to the vehicle in front, for vehicle
speed and for braking in good time. Adjust
your driving style to the traffic conditions.
Only engage cruise control when the current
road, weather and traffic conditions permit it
to be done safely. Drive carefully and
maintain a suitable distance to the vehicle in
front.
Do not use cruise control:
R in traffic conditions that do not allow you
to drive at a constant speed, e.g. heavy
traffic, on winding roads or off-road
R on slippery road surfaces. Braking or
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
General notes Cruise control maintains a constant road
speed for you. On long and steep downhill
gradients, especially if the vehicle is laden,
you must select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effect of the engine, which relieves
the load on the brake system and prevents
the brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can store any road speed above 20 mph
(30 km/h).

Cruise control should not be activated
during off-road driving.

Important safety notes G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
! Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If you fail to adapt your driving style,
SPEEDTRONIC can neither reduce the risk of
accident nor override the laws of physics.
SPEEDTRONIC cannot take account of road,
weather and traffic conditions.
SPEEDTRONIC is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good
time and for staying in lane. Only engage
SPEEDTRONIC when the current road,
weather and traffic conditions permit it to be done safely. Drive carefully and maintain a
suitable distance to the vehicle in front.
General notes SPEEDTRONIC brakes automatically so that
you do not exceed the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden or towing a trailer, you must
select shift range
1,2or 3in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly. If
you need additional braking, depress the
brake pedal repeatedly rather than
continuously.

fulfilled (Y
page 179) and the radar sensor
system must be operational.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
DISTRONIC PLUS brakes automatically so
that the set speed is not exceeded.
On long and steep downhill gradients,
especially if the vehicle is laden or towing a
trailer, you must select shift range 1,2or 3
in good time. By doing so, you will make use
of the braking effect of the engine, which
relieves the load on the brake system and
prevents the brakes from overheating and
wearing too quickly.
If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and120 mph (Canada:
200 km/h). If a vehicle is driving in front of
you, it operates in the speed range between
0 mph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked about this.

Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
R you are driving faster than 40 mph
(60 km/h).
R DISTRONIC PLUS is maintaining the
distance to a vehicle in front.
R you switch on the appropriate turn signal.
R DISTRONIC PLUS does not detect a danger
of collision.
If these conditions are fulfilled, your vehicle
is accelerated. Acceleration will be
interrupted if changing lanes takes too long
or if the distance between your vehicle and
the vehicle in front becomes too small.
i When changing lanes, DISTRONIC PLUS
monitors the left lane on left-hand drive
vehicles and the right lane on right-hand
drive vehicles.

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
vehicle occupant or from outside the
vehicle.
R the electrical system in the engine
compartment, 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
stationary and you do not need to depress the
brake.
i
Depending on the specified minimum
distance, your vehicle will come to a
standstill at a sufficient distance behind the
vehicle in front. The specified minimum
distance is set using the control on the
cruise control lever.
On steep uphill or downhill inclines or if there
is a malfunction, the transmission may also
automatically be shifted into position P.
