High-Performance Brake System - Mercedes-Benz G-Class Operator's Manual

High-performance brake system for
AMG vehicles
The high-performance brake system is only
installed on the G 63 AMG and the G 65 AMG.
The high-performance brake system is designed
for heavy loads. This may lead to noise when
braking. This will depend on:
Speed
R
Braking force
R
Environmental conditions, such as tempera-
R
ture and humidity
The wear of individual components of the brake
system, such as the brake pads/linings or brake
discs, depends on the individual driving style
and operating conditions.
For this reason, it is impossible to state a mile-
age that will be valid under all circumstances. An
aggressive driving style will lead to high wear.
You can obtain further information about this
from your authorized Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after several
hundred kilometers of driving. Compensate for
this by applying greater force to the brake pedal.
Keep this in mind, and adapt your driving and
braking accordingly during this break-in period.
Excessive heavy braking results in correspond-
ingly high brake wear. Observe the brake system
warning lamp in the instrument cluster and note
any brake status messages in the multifunction
display. For high-performance driving in partic-
ular, it is important to maintain and have the
brake system checked regularly.
Parking brake
G
WARNING
If you must brake the vehicle with the parking
brake, the braking distance is considerably
longer and the wheels could lock. There is an
increased danger of skidding and accidents.
Only use the parking brake to brake the vehi-
cle when the service brake is faulty. Do not
apply the parking brake too firmly. If the
wheels lock, release the parking brake until
the wheels begin turning again.
If you brake the vehicle with the parking brake,
the brake lamps will not light up.
If you drive on wet roads or dirt-covered surfa-
ces, road salt and/or dirt could get into the
parking brake.
In order to prevent corrosion and a reduction in
the braking power of the parking brake, observe
the following:
pull the parking brake upwards with the
R
release button depressed from time to time
before beginning the journey (
drive for approximately 110 yds (100 m) at a
R
maximum speed of 12 mph (20 km/h)
Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth on
the road surface, there is a danger of hydro-
planing occurring, even if:
you drive at low speeds.
R
the tires have adequate tread depth.
R
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
lower your speed.
R
avoid ruts.
R
brake carefully.

Driving on flooded roads
!
Do not drive through flooded areas. Check
the depth of any water before driving through
it. Drive slowly through standing water. Oth-
erwise, water may enter the vehicle interior or
the engine compartment. This can damage
the electronic components in the engine or
the automatic transmission. Water can also
be drawn in by the engine's air suction nozzles
and this can cause engine damage.
If you have to drive on stretches of road on which
water has collected, please bear in mind that:
the maximum permissible still water depth
R
depends on the vehicle equipment
you should drive no faster than at a walking
R
pace
Off-road fording
!
Under no circumstances should you accel-
erate before entering the water. The bow
