Basic settings

The extent to which the vehicle is raised or lowered depends on the basic setting selected.

Select:

Off-road level 3 for freeing the vehicle in impassable terrain at low speeds only
Off-road level 2 for driving on normal offroad terrain
Off-road level 1 for driving on easily negotiable off-road terrain
Highway/high-speed level for normal roads
The individual vehicle levels differ from highway level as follows:

+3.5 in (+ 90 mm) at off-road level 3
+2.3 in (+ 60 mm) at off-road level 2
+1.2 in (+ 30 mm) at off-road level 1
+/–0 in (+/–0 mm) at the highway level
–0.6 in (–15 mm) at the high-speed level

Off-road levels

WARNING Vehicle off-road level 3 is not intended for use 
Vehicle off-road level 3 is not intended for use on paved roads. This vehicle level is intended for clearing impracticable situations at low speed exclusively. The vehicle has a very high center of gravity in off-road level 3. This increases the overturning hazard.
Select off-road level 3 exclusively for clearing impracticable situations at low speed.
Adapt your driving style to the modified conditions.
Do not exceed a speed of 12 mph (20 km/h).
Avoid extreme, quick steering movements.
Keep in mind the vehicle's driving characteristics are modified.
You should therefore drive in off-road level 3 with particular caution as it could otherwise lead to an accident and/or serious injury to you or others.

If you drive too fast at off-road level 3, then the Reduce speed to below 12 mph (20 km/h) message appears in the multifunction display. You also hear a warning. The vehicle is lowered.

You cannot clear these messages.

Only select an off-road level when this is appropriate for road conditions. Otherwise, fuel consumption increases and handling performance may be affected.

Your selection remains stored even if you remove the SmartKey from the ignition lock.

Off-road level 3: all three indicator lamps flash

The vehicle is being adjusted to the off-road level selected. As soon as an off-road level is reached, the corresponding indicator lamp stops flashing and lights up constantly.

While the adjustment is taking place, a message appears in the multifunction display, e.g.:

The Max. speed 12 mph (20 km/h) message draws your attention to the maximum permissible speed for off-road level 3.

While the adjustment from off-road level 2 to off-road level 3 is taking place, you will see a message such as the following in the multifunction display:

Once off-road level 3 has been reached, you will see a message in the multifunction display, for example:

Off-road level 3 is canceled.

Off-road level 3 is canceled.

If you then increase the speed again, the message remains in the multifunction display. The newly set level is not displayed until the vehicle has been set to a level suitable for the current speed.

If you maintain or reduce your speed, you will see a message such as the following in the display while the vehicle is being lowered:

The vehicle is lowered to off-road level 2.

The vehicle is lowered to off-road level 2.

Once off-road level 2 has been reached, you will see a message in the multifunction display, for example:

If you select an off-road level when driving at

If you select an off-road level when driving at too high a speed, the Level selection not permitted message appears in the multifunction display.

You can select the following:

off-road level 1 up to 60 mph(96 km/h)
off-road level 2 up to 40 mph(64 km/h)
off-road level 3 up to 12 mph(20 km/h)

If you drive faster than 55 mph (88 km/h), or for longer than 20 seconds between 40 mph (64 km/h) and 55 mph (88 km/h), then offroad level 2 is canceled. The vehicle is lowered to off-road level 1.

You will see a message in the multifunction display, for example:

If you drive faster than 60 mph (96 km/h), offroad

If you drive faster than 60 mph (96 km/h), offroad level 1 is canceled. The vehicle is lowered to highway level.^^ You will see a message in the multifunction display, for example:
