powertrain, however you should d o the following:
•With damage to front axle, raise front axle. Remove
flexible drive shaft between rear axle and transfer
case
•With damage to rear axle, raise rear axle and tow
vehicle with wheel lift or dolly placed under front
wheels.
•With damage to transfer case, remove flexible drive
shafts to the drive axles.
Note:
Always install new self-locking nuts when reinstalling
the flexible drive shaft.Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (key in steering lock position 1).
Otherwise, the 4-ETS+ may become engaged which may
cause loss of towing control. Switch off the tow-away
alarm (see page 36) as well as the ESP (see page 207).

To signal turns while being towed with hazard warning
flasher in use, turn key in steering lock to position 2
and activate combination switch for left or right turn

assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.

Headlamp adjustment
Correct headlamp adjustment is extremely important.
Check and readjust headlamps at regular intervals and
when a bulb has been replaced.
For adjusting headlamp aim see page 268.Replacing bulbs
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
Wa r n i n g !
Bulbs and bulb holders can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
•scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb of repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.
