cluster displayPractical hints Car care Index Power assistance
BrakesExcessive use of road salt and other snow melting
chemicals spread on roads during the winter months
may cause a build up of moisture or residue to form on
the braking components. This build up or residue could
cause light corrosion of the braking components if the
vehicle is parked with the brakes cold. Apply steady and
even braking pressure when stopping the vehicle to
warm up and dry the brake components.
Important!
Please pay attention to the function of the brake assist
system (BAS), see page 237.
The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on and there is no
audible warning (EBB), the brake fluid level in the
reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Light Truck Center immediately.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components or salty road conditions,
the first braking action may be somewhat reduced
and increased pedal pressure may be necessary to
obtain expected braking effect. Be sure to maintain
a safe distance from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.

Te ch n i c a l

All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Light
Truck Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Caution!
When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.
After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.Driving off
Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.
Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.
When starting of f on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.
To ensure sufficient traction during off-road driving,
activate differential locks as needed, see page 253.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is us ed, t he b ra ki ng properti es of the vehic l e c an be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.

Brake warning lamp
Except Canada
Canada only
When the brake warning lamp and message appear
while the engine is running, this means:
•there is insufficient brake fluid in the reservoir
(engine running and parking brake released), or
•the parking brake is set (engine running).
If a warning tone sounds for 5 seconds and the warning
lampsÉ and - are displayed in the instrument
cluster, the electronic brake booster (EBB) has a
malfunction and is switched off. See page 242 for notes
on the electronic brake booster (EBB).Note:
If you find that the minimum mark on the brake fluid
reservoir is reached, have the brake system checked for
brake pad thickness and leaks.
Wa r n i n g !
Driving with the brake warning lamp illuminated
can result in an accident. Have your brake system
checked immediately if the brake warning lamp
stays on. Do n ot a dd b ra ke f l uid b efore check in g t he
brake system. Overfilling the brake fluid reservoir
can result in spilling brake fluid on hot engine
parts and the brake fluid catching fire. You can be
seriously burned.
