ECO mode MERCEDES-BENZ GL 2016 User Guide

If you make a call while driving, always use
hands-free mode. Only operate the telephone
when the traffic situation permits. If you are
unsure, pull over to a safe location and stop
before operating the telephone.
Bear in mind that at a speed of only 30 mph
(approximately 50 km/h) the vehicle covers a
distance of 44 ft (approximately 14 m) per
second.
Drive sensibly – save fuel Observe the following tips to save fuel: X
The tires should always be inflated to the
recommended tire pressure. X
Remove unnecessary loads. X
Remove roof carriers when they are not
needed. X
Warm up the engine at low engine speeds. X
Avoid frequent acceleration or braking. X
Have all maintenance work carried out as
indicated by the service intervals in the
Maintenance Booklet or by the service
interval display.
Fuel consumption also increases when driv-
ing in cold weather, in stop-start traffic and in
hilly terrain.
Drinking and driving
G WARNING
Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judg-
ment.
The possibility of a serious or even fatal acci-
dent is 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. Emission control
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.
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 must 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.
ECO display
The ECO display provides feedback on how
economical your driving characteristics are.
The ECO display assists you in achieving the
most economical driving style for the selec-
ted settings and prevailing conditions. Your
driving style can significantly influence the
vehicle's consumption.
The ECO display consists of three bars: R
Accel. R
Constant R
Coasting Driving tips 193
Driving and parking Z

The percent value is the average value of the
three bars. The three bars and the mean value
begin at the value of 50%. A higher percent-
age indicates a more economical driving
style.
The ECO display does not indicate the actual
fuel consumption. A fixed percentage count
in the ECO display does not indicate a fixed
consumption.
Apart from driving style, consumption is
dependent on many factors such as, e.g.: R
load R
tire pressure R
cold start R
choice of route R
electrical consumers switched on
These factors are not included in the ECO dis-
play.
The evaluation of your driving style is carried
out using the following three categories: R
Accel. (evaluation of all acceleration pro-
cesses): -
The bar fills up: moderate acceleration,
especially at higher speeds -
The bar empties: sporty acceleration R
Constant (assessment of driving behavior
at all times): -
The bar fills up: constant speed and
avoidance of unnecessary acceleration
and deceleration -
The bar empties: fluctuations in speed R
Coasting (assessment of all deceleration
processes): -
The bar fills up: anticipatory driving,
keeping your distance and early release
of the accelerator. The vehicle can coast
without use of the brakes. -
The bar empties: frequent braking
i An economical driving style specially
requires driving at moderate engine
speeds.
To achieve a higher value in the categories
Accel.
and Constant , observe the gear-
shift recommendations. i On long journeys at a constant speed, e.g.
on the highway, only the bar for Constant
will change.
i The ECO display summarizes the driving
characteristics from the start of the journey
to its completion. For this reason, the bars
change dynamically at the beginning of the
journey. On longer journeys, there are
fewer changes. For more dynamic changes,
carry out a manual reset.
For further information on the ECO display,
see ( Y
page 276).
Braking
Important safety notes
G WARNING
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.
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
braking effect, a drive wheel may not turn
for some time, e.g. on a slippery road sur-
face. This could cause damage to the drive
train. This type of damage is not covered by
the Mercedes-Benz warranty.
Do not depress the brake pedal continuously
while the vehicle is in motion, e.g. causing the
brakes to rub by constantly applying light
pressure to the pedal. This results in exces-
sive and premature wear to the brake pads.194
Driving tips
Driving and parking

If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals. To do
so, depress the brake pedal firmly when driv-
ing at a high speed. This improves the grip of
the brake pads.
You can find a description of Brake Assist
(BAS) on ( Y
page 69) or of BAS PLUS on
( Y
page 69).
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 vehi-
cle'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 corresponds 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.
High-performance brake system
(Mercedes-AMG vehicles)
The high-performance brake system is
designed for heavy loads. This may lead to
noise when braking. This will depend on: R
Speed R
Braking force R
Environmental conditions, such as temper-
ature and humidity
The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual driv-
ing style and operating conditions.
For this reason, it is impossible to state a
mileage that will be valid under all circum-
stances. An aggressive driving style will lead
to high wear. You can obtain further informa- tion about this from your authorized
Mercedes-Benz Center.
New and replaced brake pads and discs only
reach their optimum braking effect after sev-
eral hundred kilometers of driving. Compen-
sate 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 corre-
spondingly high brake wear. Observe the
& brake wear warning lamp in the instru-
ment cluster and note any brake status mes-
sages in the multifunction display. Especially
for high performance driving, it is important to
maintain and have the brake system checked
regularly.
Driving on wet roads
Hydroplaning If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if: R
you drive at low speeds. R
the 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: R
lower your speed. R
avoid ruts. R
avoid sudden steering movements. 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. Otherwise, water may enter the
vehicle interior or the engine compartment.
This can damage the electronic compo-
nents in the engine or the automatic trans-
mission. Water can also be drawn in by the196

HOLD function
General notes
The HOLD function can assist the driver in the
following situations: R
when pulling away, especially on steep
slopes R
when maneuvering on steep slopes R
when 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.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra-
dients or on slippery or loose surfaces. The HOLD function cannot hold the vehicle on
such surfaces.
Important safety notes

Important safety notes
G WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or
in the immediate vicinity of the wheel arches
when the vehicle is being lowered.
G WARNING
The vehicle is lowered if: R
you have selected the Comfort or Sport
suspension tuning and R
lock the vehicle after switching off the
engine
Persons in the vicinity of the wheel arch or the
underbody may thus become trapped. There
is a risk of injury.
Make sure that nobody is in the vicinity of the
wheel arch or the underbody when you switch
off the engine.
! The vehicle is lowered by approximately
10 mm if: R
you have selected the Sport or Comfort
suspension tuning and R
you switch off the engine and then R
lock the vehicle
When parking, position your vehicle so that
it does not make contact with the curb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
Vehicle level
Level control adapts the vehicle level auto-
matically to the current operating and driving
situation. Level control ensures the best pos-
sible suspension and constant ground clear-
ance, even with a laden vehicle. This improves
driving safety and fuel consumption.
The AIRMATIC package and ACTIVE CURVE
SYSTEM are always components of AMG
adaptive suspension system ( Y
page 218).
Due to the sportier suspension settings com-
pared to standard vehicles, the levels and
speed thresholds for sinking and raising the
vehicle are different.222

Se cure any objects on the trailer to prevent
the cargo from slipping when the vehicle is
in motion. R
When you couple up a trailer, check at reg-
ular intervals that the load is firmly secured.
If the trailer is equipped with trailer lights
and brakes, check the trailer to ensure that
these are working. R
Bear in mind that the han dlin g will be less
st able when towing a trailer than when driv-
ing wit hout one. Avoid sudden steering
movements. R
The vehicle/trailer combination is heavier,
accelerates more slowly, has a decreased
gradient cli mbin g capability and a longer
braking dist ance.
It is more susceptible to side winds and
requires more careful steering. R
If poss ible, do not brake suddenly, but
instead depr ess the brake pedal moder-
ate ly at first so that the trailer can activate
it s brakes. Then increase the pressure on
the brake pedal. R
If the automat ic transmission repeat edly
shifts between gears on uphill or down hill
gradients, shift to a lower gear using the
left-hand steering wheel paddle shifter.
A lower gear and lower speed reduce the
risk of engine failure. R
When driv ing down hill, shift to a lower gear

Loading guidelines
G WARNING
If objects, luggage or loads are not secured or
not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, particu-
larly in the event of sudden braking or a sud-
den change in direction.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
G WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate
is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open.
G WARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury. Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
The gross vehicle weight (GVW) is the vehicle
weight including fuel, vehicle tool kit, spare
wheel, installed accessories, vehicle occu-
pants and luggage/cargo.
Do not exceed the load limit or permitted
gross vehicle weight rating (GVWR) for your
vehicle. The gross load limit and the GVWR
are specified on the vehicle identification
plate on the B-pillar of the driver's door
( Y
page 416).
The load must also be distributed so that the
weight on each axle never exceeds the gross
axle weight rating (GAWR) for the front and
rear axles. The specifications for GVWR and
GAWR are on the vehicle identification plate
on the B-pillar of the driver's door
( Y
page 416).
Observe the notes on loading the vehicle
( Y
page 416).
The handling characteristics of a laden vehi-
cle are dependent on the distribution of the
load within the vehicle. For this reason, you
should observe the following notes when
transporting a load: R
Never exceed the maximum permissible
gross vehicle mass or the gross axle weight
rating for the vehicle (including occupants). R
The cargo compartment is the preferred
place to carry objects. R
Position heavy loads as far forwards as pos-
sible and as low down in the cargo com-
partment as possible. R
The load must not protrude above the
upper edge of the seat backrests. R
Always place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place. R
Always place the load behind unoccupied
seats if possible.340
