!Overfilling the fuel tank could damage the
fuel system.
!Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
!Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection sys-
tem could be blocked by particles from the
fuel can.
If you overfill the fuel tank, pressure may build
up in the fuel tank. This could cause fuel to spray
out when the fuel pump nozzle is removed.
There is a risk of injury. The fuel tank is full when
the fuel pump nozzle first switches off. End the
refueling process.

Driving and parking

Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
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 airflow
to cool the brakes more quickly.
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 braking for the
first time. This may also occur after the vehicle
has been washed.
You have to depress the brake pedal more
firmly. Maintain a greater distance from the
vehicle in front.
After driving on a wet road or having the vehicle washed, brake firmly while paying attention to
the traffic conditions. This will warm up the
brake discs, thereby drying them more quickly
and protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-
due may form on the brake discs and brake
pads. This can result in a significantly longer
braking distance.
RBrake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
RCarefully depress the brake pedal and the
beginning and end of a journey.
RMaintain a greater distance to the vehicle
ahead.
Servicing the brakes
!If the brake warning lamp lights up in the
instrument cluster and you hear a warning
tone even though the parking brake has been released, the brake fluid level may be too low.
Observe additional warning messages in the
multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines. Have the brake system checked immediately.
This work should be carried out at a qualified
specialist workshop.
!A function or performance test should only
be carried out on a 2-axle dynamometer. If
you are planning to have the vehicle tested on
such a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further infor-
mation first. Otherwise, you could damage
the drive train or the brake system.
!As the ESP®system operates automatically,
the engine and the ignition must be switched
off (the SmartKey must be in position 0or 1in
the ignition lock) if the parking brake is tested
on a brake dynamometer (for a maximum of
ten seconds).
Braking applications triggered automatically
by ESP
®may otherwise seriously damage the
brake system.
Mercedes-Benz recommends that you only have
brake pads/linings installed on your vehicle
which have been approved for Mercedes-Benz
vehicles or which correspond to an equivalent
quality standard. Brake pads/linings which have
not been approved for Mercedes-Benz vehicles
or which are not of an equivalent quality could
affect your vehicle's operating safety.
Mercedes-Benz recommends that you only use
brake fluid that has been specially approved for
your vehicle by Mercedes-Benz, or which corre-
sponds to an equivalent quality standard. Brake
fluid which has not been approved for
Mercedes-Benz vehicles or which is not of an
equivalent quality could affect your vehicle's
operating safety.
All checks and maintenance work on the brake
system must be carried out at a qualified spe-
cialist workshop.
Have brake pads installed and brake fluid
replaced at a qualified specialist workshop.
If your brake system is subject only to moderate
loads, you should test the functionality of your
brakes at regul ar interva
ls by pressing firmly on
the brake pedal at high speeds. This improves
the grip of the brake pads.
You can find a description of Brake Assist (BAS)
on (
Ypage 56).

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:
RSpeed
RBraking force
REnvironmental conditions, such as tempera-
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 noteany 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
GWARNING
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:
Rpull the parking brake upwards with the
release button depressed from time to time
before beginning the journey (
Ypage 131).
Rdrive for approximately 110 yds (100 m) at a
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:
Ryou drive at low speeds.
Rthe tires have adequate tread depth.
For this reason, in the event of heavy rain or in
conditions in which hydroplaning may occur,
you must drive in the following manner:
Rlower your speed.
Ravoid ruts.
Rbrake 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:
Rthe maximum permissible still water depth
depends on the vehicle equipment
Ryou should drive no faster than at a walking
pace

The following driving systems are specially
adapted to off-road driving:
R4ETS (Ypage 57)
RTransfer case (Ypage 162)
RDifferential locks (Ypage 162)
Observe the following notes:
Rstop your vehicle and, if necessary, shift the
transfer case to LOW RANGE(Ypage 162)
before driving off-road.
Rin transfer case position LOW RANGEthe
ECO start/stop function is not available
(
Ypage 114).
Rengage the differential locks, if necessary
(Ypage 165).
iABS, 4ETS, ESP®and BAS are deactivated
while the differential locks are engaged. This
allows the front wheels to lock briefly, so that
these can dig into a loose surface. However,
please note that locked wheels skid and can
no longer steer.
RCheck that items of luggage and loads are
stowed safely and are well secured
(
Ypage 219).
RTo avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
RAlways keep the engine running and in gear
when driving on a downhill gradient.
RAlways keep the engine running and in gear
when driving on a slope.
RDrive slowly and evenly, if necessary at a
walking pace.
REnsure that the wheels are in contact with the
ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. For safety rea-
sons, get out of the vehicle first and survey
the off-road route.
RCheck the depth of water before fording rivers
and streams.
RWhen fording, do not stop and do not switch
off the engine.
RLook out for obstacles, such as rocks, holes,
tree stumps and furrows.
RAlways keep the doors, rear door, side win-
dows and the sliding sunroof closed while the
vehicle is in motion.
RSwitch off cruise control.
RDo not stray from marked routes or paths.
RAdapt your speed to the terrain. The rougher,
steeper or more ruts on the terrain, the slower
your speed should be.
RDrive slowly and at an even speed through the
water. Ensure that a bow wave does not form
as you drive.
ROn sand, drive quickly to overcome the rolling resistance. Otherwise the vehicle's wheels
could become st
uck in loose ground.
RDo not jump with the vehicle as this will inter-
rupt the vehicle's propulsion.
RAvoid high engine speeds. Drive at appropri-
ate engine speeds (maximum 3,000 rpm).
RDo not shift the automatic transmission to
transmission position N.
RAlways check the vehicle for damage after off-
road driving.
iInformation about retrofitting special all-ter-
rain tires is available from any qualified spe-
cialist workshop.
iDo not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur-
faces.
Checklist before driving off-road
!If the engine oil warning lamp lights up while
the vehicle is in motion, stop the vehicle in a
safe place as soon as possible. Check the
engine oil level. The engine oil warning lamp
warning must not be ignored. Continuing the
journey while the symbol is displayed could
lead to engine damage.
XOil level: check the engine oil level and add oil
if necessary.
Only then does the engine receive enough oil when the vehicle is on a steep incline.
XTire-changing tool kit: check that the jack is
working and make sure you have the lug
wrench, a robust tow cable and a folding
spade in the vehicle.
XWheels and tires: check the tire tread depth
and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the wheels/
tires.
XReplace any missing valve caps.

for possible damage, especially to the under-
body and the components of the chassis.
!Drive with particular care when driving over
an obstacle while driving up or down a steep
slope.
The vehicle could otherwise tilt and slide side-
ways or tip over.
Observe the following rules when driving over
tree stumps, large stones and other obstacles:
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
RShift the transfer case to LOW RANGE
(Ypage 162).
RAvoid high engine speeds.
RRestrict the shift range to 1(Ypage 123).
RMake sure that you have enough ground
clearance before driving across an obstacle.
RDrive very slowly.
RTry to drive straight over the center of obsta-
cles: front wheel first, then rear wheel.
Traveling uphill
Approach/departure angle
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
Always observe the approach/departure angle
values (
Ypage 296).
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
RDo not drive at an angle on slopes, inclines or
gradients, but instead follow the direct line of
fall. Note that the climbing ability of your vehi- cle depends on the terrain conditions.
RBefore driving on extreme uphill and downhillgradients, shift the transfer case to LOW
RANGE (
Ypage 162).
REngage the differential locks, if necessary
(Ypage 165).
RDrive slowly.
RAccelerate gently and make sure that the
wheels are gripping.
RAvoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing resistance.
RAvoid high engine speeds – drive at an appro-
priate engine speed (maximum 3,000 rpm).
RWhen driving down an incline, make use of the
engine's braking effect. Observe the engine
speed; do not overrev the engine.
iFurther information on the maximum engine
speed: (Ypage 171).
RSelect a shift range appropriate to the gradi-
ent.
RBefore tackling steep downhill gradients,
select shift range 1(Ypage 123).
RAlways check the brakes after driving off-
road.
iHill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
(
Ypage 114).
Maximum gradient-climbing capability
Always observe the maximum gradient climbing ability values (Ypage 297).
Hilltops
When driving on an uphill gradient, reduce pres-
sure slightly on the accelerator immediately
before reaching the top of the hill (do not shift
the transmission to position N). Use the vehi-
cle's own impetus to drive over the top of the
hill.
This style of driving prevents:
Rthe vehicle from lifting off the ground on the
brow of a hill
Rloss of traction
Rthe vehicle from traveling too quickly down
the other side
Driving downhill
RBefore tackling steep downhill gradients,
select shift range 1(Ypage 123).
This way you use the engine's braking effect
to reduce the speed. If this is not sufficient,
brake gently. When doing so, make sure that
