Engaging manually G
Risk of accident
When driving on a firm road surface, only
drive in AUTO mode, never with manually
engaged differential locks. If differential
locks have been engaged manually, the
vehicle's steerability is greatly impaired
and the risk of accident thereby increased.
Do not manually engage or disengage the
differential locks while cornering. The vehi-
cle motion could otherwise be jerky. You
could lose control of the vehicle as a result
and cause an accident.
Only engage the differential locks manually if
traction in AUTO mode is insufficient.
At speeds of up to 30 km/ h,you can engage
the differential locks in this order: 3, then
4. X
Start the engine.
X Turn selector wheel 1to desired position
3 or4.
The indicator lamp in selector wheel 1
lights up at the corresponding symbol.
The engaged differential appears in the multi-
function display: 5
The differential lock for the transfer case
is locked.
The differential locks are not controlled auto-
matically. The steerability of the vehicle is
restricted considerably. Drive carefully and
accelerate gently for optimum traction.
You can switch back to AUTO mode at any
time. For safety reasons, the differential locks
disengage automatically at speeds above
50 km/h. If you stop the vehicle and switch
off the ignition for longer than ten seconds,
the differential locks switch back to AUTO
mode. Message in the multi-function display

The differential lock system has overheated
and briefly disengaged.

Driving
tips 233
Downhill gradients On long and steep downhill gradients, espe-
cially if the vehicle is laden or towing a trailer,
you must select shift range
1,2or 3in good
time.
i This also applies if you have activated
cruise control, Speedtronic or Distronic*.
This uses the braking effect of the engine and
you will not have to brake to such an extent
to maintain the same speed. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly. If you need additional braking,
depress the brake pedal repeatedly rather
than continuously.
Heavy and light loads If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
G
Risk of accident
Never depress the brake pedal continu-
ously while the vehicle is in motion, e.g.
never cause the brakes to rub by applying
constant slight pedal pressure. This causes
the brake system to overheat, increases the braking distance and can lead to the
brakes failing completely.
If the brakes have been used only moderately,
you should occasionally test their effective-
ness. To do this, brake more firmly from a
higher speed. This improves the grip of the
brakes.
Wet roads If driving in heavy rain for a prolonged period
of time without braking, there may be a
delayed reaction from the brakes, when brak-
ing for the first time. You must brake harder.
You must therefore maintain a greater dis-
tance from the vehicle in front.
Brake firmly after driving on a wet road. This
way the brake discs will become warm, drying
more quickly, which will protect them against
corrosion.
Limited braking performance on salted
roads
G
Risk of accident
The layer of salt on the brake discs and the
brake pads/linings may cause a delay in
the braking effect, resulting in a signifi- cantly longer braking distance, which could
lead to an accident.
To avoid this danger, you should:
R
occasionally brake carefully, without put-
ting other road users at risk, when you
are driving on salted roads. This helps to
remove any salt that may have started to
build up on the brake discs and the brake
pads/linings.
R maintain a greater distance to the vehicle
ahead and drive with particular care.
R carefully apply the brakes at the end of a
trip and immediately after commencing a
new trip, so that salt residues are
removed from the brake disc.
New brake pads/linings For safety reasons, Mercedes-Benz recom-
mends that you only have brake pads/linings
fitted to your vehicle that have been approved
for Mercedes-Benz vehicles or which corre-
spond to an equivalent quality standard.
Brake pads/linings which have not been
approved for Mercedes-Benz or which are not
of an equivalent quality could affect your vehi-
cle's operating safety. Operation
