Progressive steering
Depending on the vehicle equipment level, progressive steering can adjust the force of the steering
movement in a driving situation. Progressive steering only functions when the engine is running.
In urban driving, smaller steering movements are 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.

Driving profile selection and 4MOTION Active
Control
Introduction
This chapter contains information on the followingsubjects:
⇒ Selecting a driving profile (ONROADyf
⇒ Selecting a driving profile (4MOTION Action Controlyf
⇒ Adjusting the driving profile to suit your requirements
⇒ Troubleshooting
The driving profile selection contains
factory-defined driving profiles which
have different effects on the vehicle
setup. You can also set your own
vehicle setup by means of an individual
driving profile.
Different driving profiles can be selected depending on the vehicle equipment level. The effect on
the vehicle setup in the individual driving profiles depends on the vehicle equipment.
The settings available depend on the type of drive. Vehicles with a front-wheel drive come with
ONROAD driving profiles ⇒ Selecting a driving profile (ONROADyf, while vehicles with all-wheel
If the power steering is not working, the steering wheel is difficult to turn, which makes it
difficult to steer the vehicle.
•The power steering only functions 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 lock when 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.
WARNING
The ignition of the vehicle being towed 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.
NOTICE
Explanation of some technical terms
Fig. 131 Illustration: angle of gradient.
The terrain might look harmless, but there could be hidden dangers. Potholes, hollows,
ditches, precipices, obstacles, shallows, soft and boggy surfaces are often not
recognisable as such and can be covered either fully or partly by water or grass or
branches lying on the ground. Driving off-road over such terrain could cause accidents,
serious injury and also a vehicle breakdown.
•Check any unknown sections of the route on foot carefully before driving.
•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 back and choose
another route.
•Always adjust your speed and driving to match vehicle load levels and off-road,
visibility and weather conditions.
WARNING
•Always avoid traversing a slope ⇒ Traversing a slope.
•Vehicle occupants should never leave the vehicle via the doors facing down the hill

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 off-road and may even be hazardous. If you use the
cruise control system while driving off-road, you may lose control over the vehicle and
sustain severe injuries.
•Never use the cruise control system when driving off-road.

The area monitoring system is not suitable for use off-road and may even be hazardous. If
you use the area monitoring system while driving off-road, you may lose control over the
vehicle and sustain severe injuries.
•Never use the area monitoring system when driving off-road.
WARNING
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down
off-road, 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.
WARNING
Any rain entering the vehicle when the windows or glass roof are open can soak the
interior equipment and cause damage to the vehicle. Always keep the windows and glass
roof closed when driving off-road.
NOTICE
Fig. 134 On steep slopes, you should always use the doors pointing up the hill to get out of the
vehicle.
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Traversing a slope is one of the most dangerous off-road situations ⇒.
It may look harmless, but you should not underestimate the difficulty and danger of traversing a
slope. A vehicle could slide away, tip over or roll when in this position. This can cause severe or
fatal injuries for all vehicle occupants.
Check whether you can use a safer route before driving across a slope.
If you have to drive at an angle, make sure the ground is as firm as possible. The vehicle is more
likely to slip, dip and tip over on slippery or soft ground. Always be aware that uneven ground
makes the slope steeper. The vehicle could otherwise tip over and start to roll.
When driving across a slope, the wheels on the lower side of the vehicle must never enter dips or
hollows. The wheels on the upper side of the vehicle must never roll over bumps, for example
stones, tree trunks or other obstacles.
If the vehicle threatens to tip over, steer immediately into the fall line and depress the accelerator
slightly ⇒ Fig. 133. If it is not possible to drive along the fall line, then steer uphill and depress the
accelerator slightly.
The centre of gravity should be as low as possible. The weight of all vehicle occupants should be
evenly distributed. People with a larger or heavier build should sit on the higher side of the vehicle.
Remove the roof carrier and secure heavy items. The vehicle could tip over if items were to slide
suddenly ⇒.
Driving through ditches
First read and observe the introductoryinformation and safety warnings⇒
Introduction
•Check whether the tilt angle and gradient entry/exit angles are small enough to drive through
the ditch with the vehicle ⇒.
•If possible, drive through the ditch at an acute angle ⇒.
•The tilt angle may not get too large when driving through the ditch.
Never try to traverse a slope, particularly if it is too steep for the vehicle. The vehicle could
slide away, tip over or roll. Please note the following points in order to reduce the risk of
accidents and serious injuries:
•You should never underestimate the difficulty and danger of traversing a slope. 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.
•The vehicle can lose its grip and slide away sideways, tip over or roll over and roll
down the hill.
•The wheels on the lower side of the vehicle must never enter dips or hollows. The
wheels on the upper side of the vehicle must never roll over bumps, for example
stones, tree trunks or other obstacles.
•Please ensure that you can steer in the fall line on a route driving across a slope.
Choose another route if this is not guaranteed. If the vehicle threatens to tip over, steer
immediately into the fall line and depress the accelerator slightly ⇒ Fig. 133.
•If the vehicle is stopped when traversing a slope, avoid sudden movements in the
vehicle. The vehicle can lose its grip and slide away sideways, tip over or roll over and
roll down the hill.
•Vehicle occupants should never leave the vehicle via the doors facing down the hill
when parked sideways on a steep hill. This could cause the centre of gravity to move.
The vehicle could otherwise tip over or roll over and roll down the hill. To avoid this,
always leave the vehicle carefully on the side that is facing uphill ⇒ Fig. 134.
•When getting out the vehicle, please ensure that the vehicle door which opens uphill
does not close with its own weight or through carelessness thus potentially causing
injury.
WARNING
•The vehicle is stationary for longer than approximately three minutes.
•A vehicle door is opened.
•The ignition is switched off.
