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.
Fig. 116 On steep slopes: always use the doors facing 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 offroad 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 and tip over on slippery or soft ground. Always make sure that the tilt angle does not
become too large due to uneven ground. The vehicle could otherwise tip over and start to roll.
When the vehicle is tilted at a large angle, the wheels on the lower side of the vehicle must never
enter dips or hollows. The wheels on the higher side of the vehicle must never drive over bumps, for
example rocks, tree trunks or other obstacles.
If the vehicle threatens to tip over, steer immediately into the fall line and depress the accelerator
slightly ⇒ Fig. 115 . If it is not possible to steer into the fall line, then steer uphill and depress the
accelerator slightly.
The centre of gravity of the vehicle 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 ⇒ .
WARNING
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 when traversing a slope 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
higher side of the vehicle must never drive over bumps, for example stones, tree trunks or other
obstacles.
Before traversing a slope, make sure that it is possible to steer into the fall line. 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. 115 .
If the vehicle is stopped at a large tilt angle when traversing a slope, avoid sudden and uncontrolled
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 the vehicle
is stopped sideways on a slope with a large tilt angle to one side. This could cause the centre of
gravity to move to the side. The vehicle could then 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. 116 .
When getting out the vehicle, make sure that the vehicle door which opens uphill does not close
with its own weight or through carelessness, thus potentially causing injury.
Driving through ditches
First read and observe the introductoryinformation and safety warnings⇒Introduction
Check whether the ramp and tilt 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 must not become too large when driving through the ditch.
WARNING
Never drive through a ditch if the ramp and tilt angles are too steep for the vehicle and the ditch is
too deep. The vehicle could slide away, tip over or roll.
NOTICE
If you drive into the ditch at a right angle, the front wheels will fall in. The underbody of your vehicle
could bottom, get stuck and be damaged. It is then almost impossible to get out of the ditch despite
having all-wheel drive.
Stuck vehicle
First read and observe the introductoryinformation and safety warnings⇒Introduction
Rocking free a vehicle requires training and feeling for the vehicle.
If you make a mistake when rocking free the vehicle, it can sink deeper and you will need assistance
to free the vehicle.
When you cannot move forwards
Carefully dig out all the wheels and check that no other parts of the vehicle are stuck in the sand.
Select reverse gear.
Reverse in your own tracks with gentle use of the accelerator.
If this does not help, place brushwood, foot mats or sacking directly in front of the wheels to
increase grip ⇒ .
Rocking the vehicle free
Never allow the wheels to spin for long periods as this will cause the vehicle to sink deeper ⇒ .
Switch off TCS ⇒ Brake support systems .
Position the steering wheel so that it is facing straight ahead.
Reverse until the point where the wheels just start to spin.
Immediately select first gear and drive forwards until the wheels start to spin again.
Repeat driving back and forth until you have enough momentum to free yourself.
Switch the TCS on after the rocking free procedure is completed ⇒ Brake support systems .
Use the Offroad driving profile.
WARNING
No one must stand either in front or behind the vehicle, particularly if you are attempting to free a
stuck vehicle.
Spinning wheels can propel stones, brushwood, pieces of wood or other objects that are in front or
behind the wheels at enormous speed and cause potentially fatal injury.
People standing in front of or behind the vehicle could be run over if the stuck vehicle starts to move
suddenly.
After offroad driving
First read and observe the introductoryinformation and safety warnings⇒Introduction
Checklist
Clean the turn signals, lighting system, the number plate and all windows.

Press the button.
The speed limiter is switched off.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction
Control is automatically interrupted.
Malfunction. Switch off the speed limiter and go to a qualified workshop.
For safety reasons, the speed limiter does not fully deactivate itself until you release the accelerator
once or switch the system off manually.
Adaptive Cruise Control (ACC)
Introduction
This chapter contains information on the followingsubjects:
⇒ Special driving situations
⇒ Limits of ACC
⇒ Switching ACC on and off
⇒ Setting ACC
⇒ Troubleshooting
The Adaptive Cruise Control (ACC) maintains a speed selected by the driver. If the vehicle
approaches a vehicle in front, the ACC automatically adapts the speed so that a distance you have
selected is maintained.
Speed range
ACC controls the vehicle in the speed range between 30 km/h (20 mph) and 160 km/h (100 mph)
or 210 km/h (130 mph). This speed range may differ in certain markets.
Driving with ACC
You can override the ACC at any time. Control will be interrupted when you brake. If you accelerate,
control will be interrupted for the duration of the acceleration process and will then continue again.
Control by ACC is less dynamic when towing a trailer ⇒ . The ACC will not perform control operation
if the trailer's brake lights are faulty.
Does the vehicle have ACC?
The vehicle is equipped with ACC if you can make settings for ACC in the vehicle settings of the
Infotainment system ⇒ Vehicle settings menu .
Brake request
If automatic deceleration by ACC is not sufficient, ACC will request you to brake additionally by a
corresponding message on the instrument cluster. In addition, the red warning lamp lights up
and an acoustic warning is given. Brake immediately!
Radar sensor
ACC detects driving situations by means of the radar sensor at the front of the vehicle ⇒ Front view .
The radar sensor has a range of up to approximately 120 m.
WARNING
The intelligent technology used in the ACC cannot overcome the laws of physics, and functions only
within the limits of the system. Never let the extra convenience tempt you into taking safety risks
when driving. Careless or unintentional use of the Adaptive Cruise Control (ACC) can cause accidents
and lead to serious injury. The system is not a substitute for the full concentration of the driver.
Adapt your speed and distance from the vehicles ahead to suit visibility, weather, road and traffic
conditions.
Never use the ACC in poor visibility, on steep or winding roads, or on slippery road surfaces e.g. due
to snow, ice, wet roads, loose chippings, or on flooded roads.
Never use the ACC offroad or on non-surfaced roads. The ACC is designed for use on surfaced roads
only.
The ACC will not react to stationary vehicles.
The ACC will not react to persons, animals or vehicles crossing or approaching in the same lane.
Brake immediately if speed reduction by ACC is not sufficient.
Brake immediately if a request to brake appears on the instrument cluster display.
Brake if the vehicle starts rolling unintentionally after a request to brake.
Be prepared to control the speed yourself at all times.
