2017 MERCEDES-BENZ GLA SUV engine

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 forwards. Oth-
erwise, the vehicle could slip sideways, tip
and overturn.
R Before tackling steep downhill gradients, use
the left-hand steering wheel gearshift paddle
to shift to a lower gear.
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 30 km/h the front wheels lock
cyclically during braking. The digging-in effect
achieved in the process reduces the stopping
distance during off-road driving. The steerability of the vehicle is considerably reduced if the
wheels lock. Driving systems
Cruise control
General notes Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep down-
hill gradients, especially if the vehicle is laden or towing a trailer. For vehicles with automatic
transmission, you need to shift manually using
the steering wheel gearshift paddles. 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.
When the engine is running, you can use the
cruise control lever to limit the speed to any
speed between 30 km/h and the maximum
design speed of the vehicle. If the set value of
the permanent limiter is lower, then this value
applies (Y page 180).
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady speed for a prolonged period. The speed indicated in the speedometer may
differ slightly from the speed stored.
Important safety notes If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account road, weather or traffic conditions. Cruise control is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time
and for staying in lane.
Do not use cruise control:
R in road and traffic conditions that do not allow
you to maintain a constant speed, e.g. in
heavy traffic or on winding roads.
R on icy or slippery roads. Braking or acceler-
ating can cause the drive wheels to lose trac-
tion and the vehicle could then skid.
R in poor visibility, e.g. due to fog, heavy rain or
snow.
If a new driver takes over, advise the new driver
of the speed stored.

matically maintains the speed.
i Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by auto-
matically braking the vehicle. i

R always drive at adequate, but not exces-
sive, engine speeds.
R change gear in good time.
R if possible, do not change down several
gears at a time.

WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.

General notes The speed limiter restricts the vehicle speed.
The speed limiter brakes automatically to
quickly regulate the stored speed. You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. For vehi-
cles with automatic transmission, you need to
shift manually using the steering wheel gearshiftpaddles. 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 overheating and wearing too
quickly.
You can set a variable or permanent limit speed:
R Variable for a maximum permissible speed,
e.g. in built-up areas
R Permanent for restriction of the maximum
speed for technical reasons, such as when
driving on winter tyres (Y page 180)
i The speed indicated in the speedometer
may differ slightly from the maximum permis- sible speed stored.
Important safety notes If you fail to adapt your driving style, the speed

Cruise control or Distance Pilot DISTRONIC is
selected.
Vehicles with manual transmission: the lim-
iter switches off if you shift to a higher gear and as a result, the engine speed is too low.
i The last speed stored is cleared when you
switch off the engine.
Permanent limiter If you wish to restrict the maximum speed of the
vehicle for an extended period (e.g. when driving with winter tyres), the desired maximum speed
can be set with the permanent limiter.
You can use the on-board computer to limit the
speed to a value between 160 km/h and
240 km/h (Y page 229).
Shortly before the stored speed is reached, it
appears in the multifunction display. When you
confirm the message with aor%, the
display is suppressed until you next switch off
the engine. The speed will only be displayed
again once the engine has been restarted.
The permanent limiter remains active even if the variable limiter is deactivated. The driven speed
will remain below the stored speed even in the
event of kickdown. Distance Pilot DISTRONIC
General notes Distance Pilot DISTRONIC regulates the speed
and automatically helps you maintain the dis-
tance to the vehicle detected in front. The sys-
tem detects vehicles using the radar sensor sys-
tem. Distance Pilot DISTRONIC brakes automat- ically to avoid exceeding the set speed or to
maintain the designated distance from the vehi- cle in front.
If Distance Pilot DISTRONIC detects that there is
a risk of a collision with the vehicle in front, you will be warned visually and acoustically. Without
your intervention, Distance Pilot DISTRONIC
cannot prevent a collision. An intermittent warn- ing tone will then sound and the distance warn- ing lamp will light up in the instrument cluster.
Brake immediately to increase the distance to
the vehicle in front, or take evasive action, pro-
vided it is safe to do so.
Distance Pilot DISTRONIC operates in the rangebetween 0 km/h and 200 km/h. Shift to a lower gear in good time on long and
steep downhill gradients. Take particular note of
this when driving a laden vehicle. 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.
Do not use Distance Pilot DISTRONIC on roads
with steep gradients.
For Distance Pilot DISTRONIC to assist you
when driving, the radar sensor system must be
operational.
Important safety notes G
WARNING
Distance Pilot DISTRONIC does not recognise
R people or animals
R stationary objects on the road, e.g. stopped
or parked vehicles
R oncoming vehicles or crossing traffic
As a result, Distance Pilot DISTRONIC may
neither give warnings nor intervene in such
situations. There is a risk of an accident.
Always pay careful attention to the traffic sit-
uation and be ready to brake. G
WARNING
Distance Pilot DISTRONIC cannot always
clearly identify other road users and complex
traffic situations.
In such cases, Distance Pilot DISTRONIC may:
R give an unnecessary warning and then
brake the vehicle
R neither give a warning nor intervene
R accelerate or brake unexpectedly
There is a risk of an accident.
Continue to drive carefully and be ready to
brake, especially if Distance Pilot DISTRONIC
warns you. G
WARNING
Distance Pilot DISTRONIC brakes your vehicle with up to 50% of the maximum possible
deceleration. If this deceleration is not suffi-
cient, Distance Pilot DISTRONIC alerts you 180

Activating Distance Pilot DISTRONIC Activation conditions
! When Distance Pilot DISTRONIC or the
HOLD function is activated, the vehicle
brakes automatically in certain situations.
To avoid damage to the vehicle, deactivate
Distance Pilot DISTRONIC and the HOLD
function in the following or similar situations:
R when towing away
R in a car wash
To activate Distance Pilot DISTRONIC, the fol-
lowing conditions must be fulfilled:
R the engine must be running. It may take up to
two minutes of driving before Distance Pilot
DISTRONIC is ready for use.
R the electric parking brake must be released.
R ESP ®
must be switched on, but not interven-
ing.
R Parking Pilot must not be activated.
R the transmission must be in position h.
R the driver's door must be closed when you
shift from jtoh or your seat belt must be
fastened.
R the front-passenger door must be closed.
R DSR must be deactivated.
R the vehicle must not be skidding.
Activating
X Briefly pull the cruise control lever towards
you ?, up :or down A.
Distance Pilot DISTRONIC is activated.
X Keep the cruise control lever pressed up :or
down Auntil the desired speed is set.
X Remove your foot from the accelerator pedal.
Your vehicle adapts its speed to that of the
vehicle in front, but only up to the desired
stored speed.
i If you do not fully release the accelerator
pedal, the Distance Pilot passive
Distance Pilot passive mes-
sage appears in the multifunction display. The
set distance to a slower-moving vehicle in front will then not be maintained. The position
of the accelerator pedal will determine the
speed.
You can also activate Distance Pilot DISTRONIC when stationary. The lowest speed that can be
set is 30 km/h.
Driving with Distance Pilot DISTRONIC Activating at the current speed/last
stored speed G
WARNING
If you call up a stored speed and this is dif-
ferent from the current speed, the vehicle
accelerates or brakes. If you do not know
what the stored speed is, the vehicle may
accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.
X Briefly pull the cruise control lever towards
you ?.
X Remove your foot from the accelerator pedal.
The first time Distance Pilot DISTRONIC is
activated, it stores the current speed or reg-
ulates the speed of the vehicle to the previ-
ously stored speed.
Pulling away and driving
X If you want to pull away with Distance
Pilot DISTRONIC: remove your foot from the
brake pedal.
X Briefly pull the cruise control lever towards
you ?.
or X If Distance Pilot DISTRONIC is activated:
accelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically. Be ready to brake at all
times. 182
Driving systemsDriving and parking

If there is no vehicle in front, Distance Pilot
DISTRONIC operates in the same way as cruise control.
If Distance Pilot DISTRONIC detects a slower-
moving vehicle in front, it brakes your vehicle. In
this way, the distance you have selected is main- tained.
If Distance Pilot DISTRONIC detects a faster-
moving vehicle in front, it increases the driving
speed. However, the vehicle is only accelerated
up to the speed you have stored.
i Distance Pilot DISTRONIC is deactivated
when you depress the brake, except when the vehicle is stationary.
Selecting the drive program Distance Pilot DISTRONIC supports a sporty
driving style when you select the S+drive pro-
gram (Y page 159) or manual gearshifting
(Y page 161). Acceleration behind the vehicle in
front or to the set speed is then noticeably more dynamic. If you have selected the E(C in
Mercedes-AMG vehicles:) drive program, the
vehicle accelerates more gently. This setting is
recommended in stop-start traffic.
Changing lanes If you want to change to the overtaking lane on
multi-lane roads, Distance Pilot DISTRONIC sup-
ports you if:
R you are driving faster than 70 km/h
R Distance Pilot DISTRONIC is maintaining the
distance to a vehicle in front
R you switch on the respective turn signal
R Distance Pilot DISTRONIC does not currently
detect a danger of collision
If these conditions are met, your vehicle accel-
erates. Acceleration will be interrupted if chang-
ing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
Stopping If Distance Pilot DISTRONIC detects that the
vehicle in front is stopping, it brakes your vehicle
until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
i After a short period, the vehicle is secured
by the electric parking brake, thus relieving
the service brake. i
Depending on the specified minimum dis-
tance, your vehicle will come to a standstill at
a sufficient 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 is shifted automatically to
position jif:
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 is applied automati-
cally if Distance Pilot DISTRONIC is active when
the vehicle is stationary and:
R a system fault occurs
R the power supply is insufficient
If a fault occurs, the transmission may also shift
to position jautomatically.
Setting a speed Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.

Setting the 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, dependent on the vehicle speed. You
can see this distance in the multifunction dis-
play (Y page 185).
The specified minimum distance can be
changed while Distance Pilot DISTRONIC is
switched on or off.
