2018 MERCEDES-BENZ GLC engine

Observe the following rules when driving along
ruts in off-road terrain or on roads with loose
gravel: R
Activate the off-road program ( Y
page 181).R
Avoid high engine speeds. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter. R
Drive slowly. R
Where ruts are too deep, drive with the
wheels of one side on the center grassy area,
if possible.
Traveling uphill
Approach/departure angle
G WARNING
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. R
Observe the warnings for off-road driving
( Y
page 165).R
Follow the line of fall when driving on slopes
and steep inclines. R
Before driving on extreme uphill and downhill
gradients, select the off-road program
( Y
page 181).R
Drive slowly. R
Accelerate gently and make sure that the
wheels are gripping. R
Avoid high engine speeds, except when driv-
ing on sandy and muddy routes with high driv-
ing resistance. R
Use the left-hand steering wheel paddle
shifter to shift to a lower gear appropriate to
the gradient. R
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients.
Hill start assist will aid you when pulling away on
a hill. For further information about hill start
assist, see ( Y
page 140).
Do not shift into transmission position \\ when
driving off-road. You could lose control of the vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for
your vehicle, drive back down in reverse gear.
Always observe the approach/departure angle
values ( Y
page 384).
Maximum gradient-climbing capability Always observe the maximum gradient climbing
ability values ( Y
page 384).
Hilltops When driving up an uphill gradient, slightly
reduce pressure on the accelerator immediately
before reaching the brow of the hill. Make use of
the vehicle's own impetus to travel over the
brow.
This style of driving prevents: R
the vehicle from lifting off the ground on the
brow of a hill R
the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly. R
Do 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 rollover. R
Shift to a lower gear using the left-hand steer-
ing wheel paddle shifter before tackling steep
downhill gradients. R
Activate DSR. If this is not sufficient, brake
gently. When doing so, make sure that the
vehicle is facing in the direction of the line of
fall. R
Check that the brakes are working normally
after a long downhill stretch.
Off-road ABS is activated when the off-road pro-
gram is selected.
At speeds below 18 mph (30 km/h), the front
wheels lock cyclically during braking. The dig-
ging-in effect achieved in the process reduces
the stopping distance on off-road terrain. The
steerability of the vehicle is considerably
reduced if the wheels lock.168

Cruis e contro l
General notes Cruise contro l maintain s a constant road speed
fo r you. It brake s automatically in order to avoid
exceedin g th e set speed. Change into a lowe r
gear in goo d time on lon g and steep downhill
gradients. Thi s is especially important if th e
vehicle is lade n or towin g a trailer . By doin g so,
you will mak e use of th e braking effect of th e
engine. Thi s relieves th e load on th e brake sys -
te m and prevents th e brake s from overheatin g
and wearin g to o quickly.
Use cruise contro l only if road and traffic con-
dition s mak e it appropriat e to maintain a steady
speed fo r a prolonged period. You can stor e any
road speed abov e 20 mph (30 km/h).
Important safet y notesCruise contro l can neither reduce th e ris k of an
acciden t if you fai l to adapt your drivin g style no r
override th e laws of physics. Cruise contro l can -
no t take into accoun t th e road, traffic and
weather conditions. Cruise contro l is only an
aid. You are responsible fo r maintainin g a saf e
distanc e to th e vehicle in front, fo r vehicle
speed, fo r braking in goo d time and fo r stayin g in
lane. Do no t use cruise control: R
in road and traffic condition s whic h do no t
allow you to maintain a constant speed, e.g. in
heav y traffic or on windin g roadsR
on slipper y road surfaces. Brakin g or accel-
erating could cause th e drive wheels to los e
traction and th e vehicle could then skid R
when there is poo r visibility, e.g. due to fog,
heav y rain or snow
If there is a chang e of drivers, advise th e ne w
driver of th e speed stored.
i The speed indicated in th e speedometer
may diffe r slightly from th e speed stored.

Change into a lower gear in good time on long
and steep downhill gradients. This is especially
impo rtant if the veh icle is laden. By doin g 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 overheating and wear-
ing too quic kly.
If Distance Pilot DI ST RONIC detects that there is
a risk of a co llisio n, you will be warned visually
and acoustically. Without your intervention, Dis-
tance Pilot DISTRONIC cannot prevent a co lli-
sion. An intermittent warning tone will then
sound and the dist ance warning lamp will light
up in the instrument cluster. Brake immediately
in order to increase the dist ance to the veh icle in
front or take evasive action pro vide d it is safe to
do so.
Distance Pilot DI ST RONIC operates in the range
between 0 mph (0 km/h) and 120 mph
(200 km/h).
Do not use Distance Pilot DI ST RONIC while driv -
ing on roads with steep gradients.
Sin ce Distance Pilot DI ST RONIC 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

people or animals R
stationary objects on the road, e.g. st oppe d
or parked vehicles R
oncoming vehicles and crossing traffic
As a result, Distance Pilot DI ST RONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Alwa ys pay careful attention to the traff ic sit-
uation and be ready to brake.
G WARNING
Distance Pilot DI ST RONIC cannot always
clearly identify other road users and co mple x
traff ic situations.
In such cases, Distance Pilot DI ST RONIC may:R
give an unnecessary warning and then
brake the vehicle R
neither give a warning nor intervene R

and try to take evasive action.
! When Distance Pilot DI ST RONIC or the
HOLD function are activated, the vehicle
brakes automatically in certain situations.Driving systems 171
Driving and parking Z

When you change lanes, Distance Pilot
DISTRONIC monitors the left lane (on left-hand-
drive vehicles) or the right lane (on right-hand-
drive vehicles).
Stopping
G WARNING
If you leave the vehicle when it is only being
braked by Distance Pilot DISTRONIC, it could
roll away if: R
there is a malfunction in the system or in
the voltage supply. R
Distance Pilot DISTRONIC is switched off
using the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle R
the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with. R
the battery is disconnected R
the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always deactivate
Distance Pilot DISTRONIC and secure the
vehicle against rolling away.
Further information on deactivating Distance
Pilot DISTRONIC ( Y
page 176).
If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
to a stop.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.
Depending on the specified minimum distance,
your vehicle will come to a standstill at a suffi-
cient distance behind the vehicle in front. The
specified minimum distance is set using the
control on the cruise control lever. When Distance Pilot DISTRONIC is activated,
the transmission shifts automatically to position
] if: R
the driver's seat belt is not fastened and the
driver's door is open. R
the engine is switched off, unless it is auto-
matically switched off by the ECO start/stop
function.
The electric parking brake secures the vehicle
automatically if Distance Pilot DISTRONIC is
activated when the vehicle is stationary and: R
a system malfunction occurs. R
the power supply is insufficient.
If a malfunction occurs, the transmission may
also be shifted to position ] automatically.
Setting a speed X
Push cruise control lever up C for a higher
speed or down D for a lower speed.X
To adjust the set speed in 1 mph incre-
ments (1 km/h increments): briefly push
the cruise control lever up C or down D to
the pressure point.
Every time the cruise control lever is pressed
up C or down D the last speed stored is
increased or reduced. X
To adjust the set speed in 5 mph incre-
ments (10 km/h increments): briefly push
the cruise control lever up C or down D
beyond the pressure point.
Every time the cruise control lever is pressed
up C or down D , the last speed stored is
increased or reduced.
i If you accelerate to overtake, Distance Pilot
DISTRONIC adjusts the vehicle's speed to the
last speed stored after you have finished over-
taking.
Setting a specified minimum distance You can set the specified minimum distance for
Distance Pilot DISTRONIC by varying the time
span between one and two seconds. With this
function you can set the minimum distance that
Distance Pilot DISTRONIC maintains to the vehi-
cle in front, depending on vehicle speed. You
can see this distance in the multifunction dis-
play ( Y
page 175).
Make sure that you maintain the minimum dis-
tance to the vehicle in front as required by law.174

DSR
General notes DSR (Downhill Speed Regulation) is an aid to
assist you when driving downhill that is available
only in vehicles with the Off-Road Engineering
package.
It keeps the speed of travel at the speed selec-
ted on the on-board computer. The steeper the
downhill gradient, the greater the DSR braking
effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position [ , ^
or \\ . You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes
G WARNING
If the speed driven and the set speed deviate
and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ-
ence between driving speed and the set
speed.
DSR can neither reduce the risk of accident if
you fail to adapt your driving style nor override
the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for maintaining a
safe distance to the vehicle in front, for vehicle
speed, for braking in good time and for staying in
lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not always be able to keep to the set speed, depend-
ing on road surface and tire conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.
Further information about "Driving off-road"
( Y
page 165).
Activating/deactivating DSR If you activate DSR and no speed has been set,
the vehicle decelerates to 4 mph (6 km/h).
You can activate DSR only when driving at
speeds below 25 mph (40 km/h).
