Driving tips
General driving tips
Important safety notes
GWARNING
Always remember that you must concentrate primarily on driving the vehicle. The driver's
concentration must always be directed pri-
marily at road traffic. For your own safety and
that of others, we recommend that you stop
the vehicle at a safe place and in accordance
with the traffic conditions before making or
accepting a phone call.
Comply with all legal requirements if you use
the telephone while driving. Use the hands-
free system and only use the telephone when
road, weather and traffic conditions permit. In
some jurisdictions, it is forbidden for drivers
to use mobile phones while driving.
Only operate COMAND (Cockpit Managementand Data System) in compliance with all legal
requirements and when the road, weather and
traffic conditions permit. You may otherwise
not be able to observe the traffic conditions,
endangering yourself and others.
Remember that your vehicle covers a distance
of 44 ft (approximately 14 m)a second when
it is traveling at only 30 mph (approximately
50 km/h).
GWARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
Drive sensibly – save fuel
Observe the following tips to save fuel:
XThe tires should always be inflated to the rec-
ommended tire pressure.
XRemove unnecessary loads.
XRemove roof carriers when they are not nee-
ded.
XWarm up the engine at low engine speeds.
XAvoid frequent acceleration or braking.
XHave all maintenance work performed at the
service intervals specified in the Maintenance
Booklet or indicated by the service interval
indicator.
Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly ter-
rain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs and driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
132Driving tips
Driving and parking

affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-dent are greatly increased when you drink or
take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or tak-
ing drugs.
Pedals
GWARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use
loose floormats and do not place floormats on
top of one another.
Emission control
GWARNING
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon mon-
oxide (CO), and inhaling it can cause uncon-
sciousness and possible death.
Do not run the engine in confined areas (such as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are enter-
ing the vehicle while driving, have the cause
determined and corrected immediately. If you
must drive under these conditions, drive only
with at least one window fully open at all
times.
Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work at peak efficiency if
they are serviced exactly in accordance with the
manufacturer's specifications. For this reason,
all work on the engine should only be carried out by qualified and authorized Mercedes-Benz
technicians.
The engine settings must not be changed under
any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the Mercedes-
Benz service requirements. Details can be found
in the Maintenance Booklet.
Braking
Important safety notes
GWARNING
If you activate the LOW off-road gear while
driving on a slippery road surface, the wheels
may lose traction:
Rif you remove your foot from the accelera-
tor pedal when driving
Rif off road ABS intervenes when braking
If the wheels lose traction. the vehicle can no
longer be steered. There is an increased dan- ger of skidding and accidents.
Never activate the LOW off-road gear while
driving on a slippery road surface.
Downhill gradients
!On long and steep gradients, you must
reduce the load on the brakes by shifting early
to a lower gear. This allows you to take
advantage of the engine braking effect and
helps avoid overheating and excessive wear
of the brakes.
When you take advantage of the engine brak-
ing effect, a drive wheel may not turn for some
time, e.g. on a slippery road surface. This
could cause damage to the drive train. This
type of damage is not covered by the
Mercedes-Benz warranty.
Heavy and light loads
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.
Driving tips133
Driving and parking
Z

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).

Driving and parking

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

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.
138Driving tips
Driving and parking

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
140Driving tips
Driving and parking

the vehicle is facing in the direction of the line
of fall.
RObserve the notes on driving in mountainous
terrain (Ypage 140).
RDrive slowly.
RDo not drive at an angle down steep inclines.
Steer into the line of fall and drive with the
front wheels aligned straight. Otherwise, the
vehicle could slip sideways, tip and roll over.
RCheck that the brakes are working normally
after a long downhill stretch.
iThe special off-road ABS setting (Ypage 56)
enables repeated, brief, precise locking of the
front wheels, which leads to the wheels dig-
ging into the loose ground. Note that when
the front wheels are fully braked, they slide
easily over the surface of the ground, making
it difficult to steer.
Driving systems
Cruise control
Important safety notes
GWARNING
The brake pedal moves when cruise control
brakes the vehicle. A foot in the area under
the brake pedal could become trapped. The
movement of the pedal, and therefore the
vehicle's ability to brake, may be restricted by objects in the area under the brake. There is a
risk of an accident and injury.
Do not place your foot under the brake pedal. Keep the area under the brake pedal free from
obstructions.
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of accident nor
override the laws of physics. Cruise control can-
not take account of road, weather and traffic
conditions. Cruise control is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed and for braking in good
time. Adjust your driving style to the traffic con-
ditions. Only engage cruise control when the
current road, weather and traffic conditions per-
mit it to be done safely. Drive carefully and
maintain a suitable distance to the vehicle in
front. Do not use cruise control:
Rin traffic conditions that do not allow you to
drive at a constant speed, e.g. heavy traffic,
on winding roads or off-road
Ron slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid
Rwhen there is poor visibility, e.g. due to fog,
heavy rain or snow
General notes
Cruise control maintains a constant road speed
for you. On long and steep downhill gradients,
especially if the vehicle is laden, you must select
shift range
1,2 or 3in good time. By doing so,
you will make use of the braking effect of the
engine. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly.
Use cruise control only if road and traffic con-
ditions make it appropriate to maintain a steady
speed for a prolonged period. You can store any
road speed above 20 mph (30 km/h).
iCruise control should not be activated when
driving off-road.
