ction if:
R the vehicle is stationary
R the engin eisrunning or if it has been auto-
matically switched off by the ECO start/stop
function
R the driver's door is close dorifyour seat belt
is fastened

! Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz implied warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
! When testin
gthe parking brake, operate the
vehicle only briefly (for amaximum of ten sec-
onds) on abrake test dynamometer. When
doing this, turn the key to position 0or 1in
the ignition. Failure to do this can cause dam- age to the drive train or the brake system.
! Af
unction or performanc etest should only
be carried out on atwin-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult aqualified
workshop. You could otherwise damage the
drive train or the brake system.
The all-wheel drive system ensures that all four
wheels are permanently driven. The all-wheel
drive system improves vehicle traction together with ESP ®
and 4ETS if adrive wheel spins due to
insufficient grip.
Only when you use winter tyres (M+S tyres) in
wintry driving condition sand, if necessary, snow
chains (Y page 237). Only in this way can the
maximum effect of all-wheel drive be achieved.
