The steering assistance provided by the electromechanical steering system automatically adjusts to
the vehicle speed, steering wheel torque and steering wheel angle. The electromechanical steering
functions only when the engine is running.
You will need considerably more strength than normal to steer the vehicle if the power steering is
reduced or has failed completely.
Counter steering assistance
Counter steering assistance provides the driver with steering assistance in critical driving situations.
Additional steering forces assist the driver when counter steering ⇒ .
Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the steering response in a
driving situation. Progressive steering functions only when the engine is running.
In urban traffic, less steering input is required when parking, manoeuvring, or turning sharply.
When driving on country roads or on the motorway, the progressive steering provides a more
sporty, direct steering response, and a dynamic feel.
WARNING
If the power steering is not working, the steering wheel is difficult to turn, which makes it difficult to
steer the vehicle.
Depending on the vehicle equipment level, the power steering functions only when the engine is
running.
Never allow the vehicle to roll if the engine is switched off.
Never remove the vehicle key from the ignition if the vehicle is in motion. The steering column lock
may be activated and it will no longer be possible to steer the vehicle.
WARNING
In conjunction with the ESC, counter steering assistance provides the driver with assistance when
steering in critical driving situations. The driver must steer the vehicle at all times. Counter steering
assistance does not steer the vehicle.
NOTICE
When the vehicle is towed, the ignition must be switched on to prevent the steering wheel from
locking, and so that the turn signals, horn, wipers and window washer system can be used.

You can also drive vehicles with all-wheel drive offroad in addition to on normal roads. It is very
important to read the contents of this section before driving offroad.
The vehicle is not built for expedition-type journeys.
The examples given in this chapter are an aid for safe offroad driving. However, we cannot predict
whether these guidelines will be valid for all situations that could occur.
The many different types of terrain and the associated risks and dangers make it impossible to
describe all possible driving situations. The examples are only general guidelines which are intended
to help you to drive offroad safely. It is crucial that you know what to expect when you drive into
offroad terrain you are unfamiliar with. This will enable you to assess potential dangers in advance.
The driver can use 4MOTION Active Control to activate a variety of vehicle settings in an all-wheel
drive vehicle as required ⇒ Setting a driving profile .
Checklist
Before driving offroad for the first time, take the following steps so you can operate and drive the
vehicle safely offroad:
Observe the basic safety notes Safety instructions for offroad driving.
Familiarise yourself with the vehicle controls.
Check and adjust the seat position Sitting position and fasten the seat belts Seat belts.
Check distance to steering wheel and adjust Steering wheel.
Always wear suitable, well-fitting shoes that provide good grip for your feet when operating the
pedals.
Safety instructions for offroad driving
First read and observe the introductoryinformation and safety warnings⇒Introduction
WARNING
The intelligent vehicle technology cannot overcome the laws of physics, and functions only within
the limits of the system. Despite ABS, instability through locked wheels can occur on adverse terrain
– e.g. if you brake hard when driving on a loose gravel road. The Electronic Stability Control will be
able to stabilise the vehicle only to a limited extent in these circumstances.
WARNING
Driving offroad can be dangerous and could cause accidents, serious injury, damage to the vehicle
and also a vehicle breakdown far from any assistance.
Never select a dangerous route and never take risks that could endanger you and your passengers. If
you cannot drive on or if you are in any doubt about the safety of the route, turn round and choose
another route.
Even terrain that looks harmless can be difficult and dangerous, and could get you and your
passengers into difficulties. We recommend inspecting the terrain on foot beforehand.
WARNING
Always avoid traversing a slope ⇒ Traversing a slope .
Vehicle occupants should never leave the vehicle via the doors facing down the hill when stopped
sideways on a steep hill. The combined centre of gravity of the vehicle and its payload (vehicle
occupants and payload) can shift and cause the vehicle to roll over and roll down the incline. Always
leave the vehicle slowly via the doors which open up the incline ⇒ Traversing a slope .
WARNING
The cruise control system has been designed for use on surfaced roads only. The cruise control
system is not suitable for use offroad and may even be hazardous. If you use the cruise control
system while driving offroad, you may lose control over the vehicle and sustain serious injuries.
Never use the cruise control system when driving offroad.
WARNING
The area monitoring system (Front Assist) was developed for use on surfaced roads only. The area
monitoring system is not suitable for use offroad and may even be hazardous. If you use the area
monitoring system while driving offroad, you may lose control over the vehicle and sustain serious
injuries.
Never use the area monitoring system when driving offroad.
WARNING
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down offroad,
accidents and serious injuries.
When the fuel level is too low, the fuel supply to the engine could be irregular, especially when
driving up or down hills and inclines.
The steering, all driver assist systems and brake support systems will not function if the engine
sputters or stops completely due to a lack of fuel or irregular fuel supply.
Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and breaking
down.
NOTICE
Always adjust your speed and driving to match vehicle load levels and visibility, terrain and weather
conditions.
Driving on sand and mud
First read and observe the introductoryinformation and safety warnings⇒Introduction
Always drive at a steady speed through sand or mud and, do not carry out any manual gear changes
or stop the vehicle.
Check whether ESC is active. The indicator lamp or in the instrument cluster display must not
light up ⇒ Brake support systems .
Keep the vehicle moving constantly.
Use the Offroad driving profile ⇒ Setting a driving profile .
Select a suitable gear and remain in this gear until you have reached more solid ground ⇒ Changing
gear correctly .
If the tyres have lost their grip, turn the steering wheel to and fro quickly. This can briefly give the
tyres on the front wheels better grip for these ground conditions.
Driving through sand
Do not under any circumstances reduce the tyre pressure to drive through sand ⇒ . If the tyre
pressure has been reduced for driving through sand, the correct tyre pressure must always be
restored before driving on. Driving with reduced tyre pressure can lead to a loss of control over the
vehicle and increase the risk of serious and fatal injuries.
Driving through mud
Do not change speed or direction. The tyres can lose their traction when driving through mud. If the
vehicle slides, steer in the direction needed to get the vehicle under control.
WARNING
Driving through mud and sand can be dangerous. The vehicle can slide uncontrollably. This increases
the risk of injury. Always drive carefully through sand and mud.
Never choose an unsafe route or take a risk which could endanger you or your passengers. If you are
in any doubt about the safety of the route, turn round and choose another way.
WARNING
Incorrect tyre pressure can cause severe or even fatal accidents.
Incorrect tyre pressures will increase the levels of wear on the tyres and will negatively affect the
vehicle's handling.
An incorrect tyre pressure can cause overheating, sudden tyre damage including tyre bursts and
ripping of the tread surface and thus to a loss of control over the vehicle.
Driving on steep terrain
First read and observe the introductoryinformation and safety warnings⇒Introduction
Driving uphill or downhill
Get out of the vehicle and assess the situation before you attempt to drive up or down a hill:
Walk along the section and check the firmness of the ground. Look out for obstacles and other
hidden dangers ⇒ .
Check the section beyond the hill.
You should not follow the route if it is too steep, uneven or if the ground surface is too loose. Select
another route.
Drive slowly and at constant speed straight up or down a slope.
Accelerate only to the speed you need to climb the slope. Too much acceleration can cause the
wheels to spin and lead to a loss of control of the vehicle. Insufficient throttle increases the
probability of stalling the engine.
Never attempt to stop or turn on a slope.
Avoid allowing the engine to stall.
Do not change gear or engage the clutch when climbing a slope.
Use the offroad display ⇒ Offroad display .
If you cannot continue to drive up a hill
Never turn the vehicle around on an uphill gradient.
If the engine has stalled, depress the footbrake and start the engine again.
Select reverse gear and reverse back slowly in a straight line.
Use the foot brake to keep a constant speed until you have reached a safe place.
Driving downhill
Never exceed the tilt angle of the vehicle! If, in an emergency, you have to traverse the slope when
driving down it and the vehicle threatens to tip over, steer into the fall line immediately.
There is an increased risk of rolling over when driving downhill. Concentrate on steering the vehicle
when driving downhill in particular.
Use the offroad display on steep downhill stretches ⇒ Offroad display .
Drive down steep inclines in first gear.
Use the foot brake sparingly in order not to lose control of the vehicle.
