ignition MERCEDES-BENZ G-Class 2016 W463 Workshop Manual

!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 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

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.

The HOLD function can assist the driver in the
following situations:
Rwhen pulling away, especially on steep slopes
Rwhen maneuvering on steep slopes
Rwhen waiting in traffic
The vehicle is kept stationary without the driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
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.
Activation conditions
You can activate the HOLD function if:
Rthe vehicle is stationary
Rthe engine is running or if it has been auto-
matically switched off by the ECO start/stop
function
Rthe engine is running
Rthe driver's door is closed or your seat belt is
fastened
Rthe transmission is in position D,R or N
RDISTRONIC PLUS is deactivated

When leaving the vehicle, it can still roll away despite being braked by the HOLD function if:
Rthere is a malfunction in the system or in
the voltage supply.
Rthe HOLD function has been deactivated by
pressing the accelerator pedal or the brake
pedal, e.g. by a vehicle occupant.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected
There is a risk of an accident.
If you wish to exit the vehicle, always turn off the HOLD function and secure the vehicle
against rolling away.
The HOLD function is deactivated automatically if:
Ryou accelerate and the transmission is in
position Dor R.
Ryou shift the transmission to position P.
Ryou depress the brake pedal again with a cer-
tain amount of pressure untilëdisap-
pears from the multifunction display.
Ryou activate DISTRONIC PLUS.
On steep uphill or downhill gradients or if there
is a malfunction, the transmission may also be
automatically shifted into position P.
Permanent all-wheel drive
!
Never tow the vehicle with one axle raised.
This may damage the transfer case. Damage
of this sort is not covered by the Mercedes-
Benz Limited Warranty. All wheels must
remain either on the ground or be fully raised.
Observe the instructions for towing the vehi-
cle with all wheels in full contact with the
ground.
!When testing the parking brake, operate the
vehicle only briefly (for a maximum of ten sec-
onds) on a brake test dynamometer. When
doing this, turn the SmartKey to position 0or
1 in the ignition. Failure to do this can cause
damage to the drive train or the brake system.

!A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
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
(
Ypage 137).
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.
