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
Off-road fording
!Under no circumstances should you accel-
erate before entering the water. The bow
Driving tips135
Driving and parking
Z
wave could cause water to enter and damage
the engine and other assemblies.
!Do not open any of the vehicle's doors while
fording. Otherwise, water could get into the
vehicle interior and damage the vehicle's
electronics and interior equipment.
iYou may only drive through fresh water.
RObserve the safety notes (Ypage 137) and
the general notes (Ypage 137) on off-road
driving.
REstablish how deep the water is and the char-
acteristics of the body of water before ford-
ing.
RSwitch off the air-conditioning system.
RShift the transfer case to LOW RANGE
(Ypage 162).
REngage the differential locks, if necessary
(Ypage 165).
RRestrict the shift range to 1or 2
(Ypage 123).
RAvoid high engine speeds.
REnter and exit the water at a flat place and at
a steady walking pace.
RDrive slowly and at an even speed through the
water.
RDo not stop and do not switch off the engine.
RWater offers a high degree of resistance, and
the ground is slippery and in some cases
unstable. Therefore, it is difficult and danger-
ous to pull away in the water.
REnsure that a bow wave does not form as you
drive.
RClean any mud from the tire tread after ford-
ing.
RApply the brakes to dry them after fording.
Always observe the fording depth values
(
Ypage 296).
Winter driving
General notes
GDANGER
If the exhaust pipe is blocked or adequate
ventilation is not possible, poisonous gases
such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle
becomes trapped in snow. There is a risk of
fatal injury.
If you leave the engine or the auxiliary heatingrunning, make sure the exhaust pipe and area
around the vehicle are clear of snow. To
ensure an adequate supply of fresh air, open a
window on the side of the vehicle that is not
facing into the wind.
GWARNING
If you have installed unsuitable snow chains to the front wheels, they may drag against the
vehicle body or chassis components. This
could cause damage to the vehicle or the
tires. There is a risk of an accident.
Only equip the front wheels with suitable
snow chains that guarantee sufficient dis-
tance to the vehicle body and to the suspen-
sion components in every driving situation.
Always follow the manufacturer's installation
instructions when installing the snow chains.
Have your vehicle winter-proofed at a qualified
specialist workshop at the onset of winter.
Observe the notes in the "Winter operation" sec- tion (
Ypage 264).
Driving with summer tires
Observe the notes in the "Winter operation" sec-tion (Ypage 264).
Slippery road surfaces
GWARNING
If you shift down on a slippery road surface in an attempt to increase the engine's braking
effect, the drive wheels could lose their grip.
There is an increased danger of skidding and
accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
136Driving tips
Driving and parking
ingly. Drive carefully and maintain a suitable dis-
tance to the vehicle in front.
When DISTRONIC PLUS detects a risk of colli-
sion with the vehicle in front but is unable to
sufficiently decelerate the vehicle in order to
maintain the set distance from the vehicle in
front, you will be warned visually and acousti-
cally. DISTRONIC PLUS cannot prevent a colli-
sion without your intervention. An intermittent
warning tone will then sound and the distance
warning lamp will light up in the instrument clus-
ter. Brake immediately in order to increase the
distance from the vehicle in front, or take eva-
sive action, provided it is safe to do so.
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore, always
pay attention to traffic conditions even when
DISTRONIC PLUS is activated. Otherwise, you
may fail to recognize dangers in time, cause an
accident and injure yourself and others.
In particular, the detection of obstacles can be
impaired if:
Rthe sensor is dirty or covered
Rthere is snow or heavy rain
Rthere is interference by other radar sources
Rthere is the possibility of strong radar reflec-
tions, for example, in parking garages.
If DISTRONIC PLUS is activated, the vehicle
brakes automatically in certain situations. This
can happen unexpectedly, especially when tow-
ing or in a car wash. There is a risk of an acci-
dent. In these or similar situations, deactivate
DISTRONIC PLUS.
If you want DISTRONIC PLUS to assist you, the
following activation condit
ions must be fulfilled
(Ypage 149) and the radar sensor system must
be operational.
General notes
DISTRONIC PLUS regulates the speed and auto- matically helps you maintain the distance to the
vehicle detected in front. DISTRONIC PLUS
brakes automatically so that the set speed is not
exceeded.
On long and steep downhill gradients, especially
if the vehicle is laden or towing a trailer, you
must select shift range 1,2or 3in good time. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and prevents the brakes from overheat-
ing and wearing too quickly. If DISTRONIC PLUS detects a slower-moving
vehicle in front, your vehicle is braked in order to
maintain the preset distance to the vehicle in
front.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control in the
speed range between 20 mph (Canada:
30 km/h) and 120 mph (Canada: 200 km/h). If
a vehicle is driving in front of you, it operates in
the speed range between 0 mph (0 km/h) and
120 mph (Canada: 200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves, it
can resemble the radar detectors of the respon-
sible authorities. You can refer to the relevant
chapter in the Operator's Manual if questions
are asked about this.

General notes
Blind Spot Assist uses a radar sensor system to
monitor both the left and right sides of your
vehicle. It supports you from a speed of approx-
imately 20 mph (30 km/h). A warning display in
the exterior mirrors draws your attention to
vehicles detected in the monitored area. If you
then switch on the corresponding turn signal to change lanes, you will also receive a visual and
audible collision warning. For this purpose, Blind
Spot Assist uses sensors in the rear bumper.
Monitoring range of the sensors
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if the vehicles are driving on the inner side
of their lane.
Due to the nature of the system:
Rwarnings may be issued in error when driving
close to crash barriers or similar solid lane
borders.
Rthe warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.
The two sensors for Blind Spot Assist are inte-
grated into the sides of the rear bumper. Make
sure that the bumper is free of dirt, ice or slush
in the vicinity of the sensors. The radar sensors
must not be covered, for example by rear bicycle
racks or overhanging loads. Following a severe
impact or in the event of damage to the bump-
ers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may otherwise not work prop-
erly.

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 a drive wheel spins due to
insufficient grip.
If a drive wheel spins due to insufficient grip:
ROnly depress the accelerator pedal as far as
necessary when pulling away.
RTake your foot off the accelerator, slowly,
while the vehicle is in motion.
The permanent all-wheel drive system can nei-
ther reduce the risk of accident nor override the
laws of physics if you fail to adapt your driving
style or if you are inattentive. The all-wheel drive
system cannot take into account road, weather
or traffic conditions. The all-wheel drive system
is only an aid. You are responsible for maintain-
ing a safe distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in lane.
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains
(
Ypage 264). Only in this way can the maximum
effect of all-wheel drive be achieved.
For information on driving off-road, see

PARKTRONIC
Important safety notes
!When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. PARKTRONIC
does not detect such objects when they are in the immediate vicinity of the vehicle. You
could damage the vehicle or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes on a truck
or a pneumatic drill could cause PARKTRONIC
to malfunction.
PARKTRONIC may not function correctly on
uneven terrain. PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and audi-
bly the distance between your vehicle and an
object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting a parking
space. Ensure that the areas in front, behind and
to the side of the vehicle are safe before maneu-
vering, parking or pulling away. There must not
be any persons, animals or objects in the area in
which you are maneuvering.
PARKTRONIC does not take into account any
persons or objects located below or above the
detection range. As a result, PARKTRONIC can-
not warn you about objects in this area.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper.

Towing a trailer
Notes on towing a trailer
Important safety notes
GWARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
GWARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
by increasing the speed. Reduce vehicle
speed and do not countersteer. Apply the
brake as necessary.
GWARNING
If you install a ball coupling other than the one
delivered with the vehicle, the trailer tow hitch
and the rear axle may be overloaded. This
applies especially if the ball coupling in ques-
tion is longer or angled differently. This could
seriously impair the driving characteristics
and the trailer can come loose. There is a risk
of an accident.
Only install the ball coupling delivered with
the vehicle or a ball coupling that is designed
to meet your trailer towing requirements. Do
not modify the ball coupling or the trailer tow
hitch.
GWARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
166Towing a trailer
Driving and parking
Always install and secure the ball coupling asdescribed. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
Please observe the manufacturer's operating
instructions for the trailer coupling if a detach-
able trailer coupling is used.
Exceeding the maximum permissible nose-
weight may cause damage to the following:
Ryour vehicle
Rthe trailer
Rthe ball coupling
Rtrailer tow hitch
The vehicle/trailer combination could become
unstable.
If the noseweight used is lower than the mini-
mum permissible noseweight, the vehicle/
trailer combination could also become unstable.
To avoid hazardous situations:
Rmake sure to check the noseweight before
each journey
Ruse a drawbar noseweight as close as possi-
ble to the maximum noseweight
Rdo not exceed the maximum permissible
noseweight
Rdo not use a noseweight lower than the min-
imum permissible trailer drawbar noseweight
When backing up the vehicle towards the trailer,
make sure there is nobody between the trailer
and the vehicle.
The applicable permissible values, which must
not be exceeded, can be fou nd:
Rin your vehicle documents
Ron the type plate of the trailer tow hitch and
trailer
Ron the vehicle identification plate
Couple and uncouple the trailer carefully. If you
do not couple the trailer to the towing vehicle
correctly, the trailer could become detached.
Make sure that the following values are not
exceeded:
Rthe permissible trailer drawbar noseweight
Rthe permissible trailer load
Rthe permissible rear axle load of the towing
vehicle
Rthe maximum permissible gross vehicle
weight of both the towing vehicle and the
trailer When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
The vehicle/trailer combination:
Ris heavier
Ris restricted in its acceleration and gradient-
climbing capability
Rhas an increased braking distance
Ris affected more by strong crosswinds
Rdemands more sensitive steering
Rhas a larger turning radius
This could impair the handling characteristics.
Adapt your driving style accordingly. Maintain a
safe distance. Drive carefully.
When towing a trailer, always adjust your speed
to the current road and weather conditions. Do
not excee
d the maximum permissible speed for
your vehicle/trailer combination.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle in the "Technical
data" section (
Ypage 297).
General notes
RDo not exceed the legally prescribed maxi-
mum speed for vehicle/trailer combinations
in the relevant country.
This lowers the risk of an accident.
ROnly install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
RIf you do not need the ball coupling, remove
the ball coupling from the ball coupling
recess. This reduces the risk of damage to the
ball coupling.
iCheck the tire pressures when towing a
trailer. You will find the values in the tire pres-
sure table in the fuel filler flap of the vehicle
(
Ypage 266).
You will find installation dimensions and loads
under "Technical data" (
