lock MERCEDES-BENZ GLA 2019 Manual PDF

For this reason, in the event of heavy rain or inconditions in which hydroplaning may occur,you must drive in the following manner:
Rlower your speed
Ravoid ruts
Ravoid sudden steering movements
Rbrake carefully
Driving on flooded roads
!Bear in mind that vehicles traveling in frontor in the opposite direction create waves.This may cause the maximum permissiblewater depth to be exceeded.
Failure to observe these notes may result indamage to the engine, electrical systemsand transmission.
If you have to drive on stretches of road onwhich water has collected, please bear in mindthat:
Rin the case of standing water, the waterlevel may be no higher than the lower edgeof the vehicle body
Ryou should drive no faster than walking pace
Winter driving
GWARNING
If you shift down on a slippery road surface
in an attempt to increase the engine's brak-
ing effect, the drive wheels could lose their
grip. There is an increased danger of skid-
ding and accidents.
Do not shift down for additional engine brak-
ing on a slippery road surface.
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 vehi-
cle becomes trapped in snow. There is a risk
of fatal injury.
If you leave the engine or the auxiliary heat-
ing running, 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.
Have your vehicle winter-proofed at a qualifiedspecialist workshop at the onset of winter.
Drive particularly carefully on slippery roadsurfaces. Avoid sudden acceleration, steeringand braking maneuvers. Do not use cruisecontrol or Active Distance Assist DISTRONIC.
If the vehicle threatens to skid or cannot bestopped when moving at low speed:
XShift the transmission to position\\.
XTry to bring the vehicle under control usingcorrective steering.
The outside temperature indicator is notdesigned to serve as an ice-warning deviceand is therefore unsuitable for that purpose.Changes in the outside temperature are dis-played after a short delay.
Indicated temperatures just above the freezingpoint do not guarantee that the road surface isfree of ice. The road may still be icy, especiallyin wooded areas or on bridges.
You should pay special attention to road con-ditions when temperatures are around freezingpoint.
For more information on driving with snowchains, see (Ypage 307).
For more information on driving with summertires, see (Ypage 306).
Observe the notes in the "Winter operation"section (Ypage 306).
Off-road driving
Important safety notes
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.
Driving tips153
Driving and parking
Z

RActivate DSR. If this is not sufficient, brakegently. When doing so, make sure that thevehicle is facing in the direction of the lineof fall.
RCheck that the brakes are working normallyafter a long downhill stretch.
Off-road ABS is activated when the off-roadprogram is selected.
At speeds below 18 mph (30 km/h), the frontwheels lock cyclically during braking. The dig-ging-in effect achieved in the process reducesthe stopping distance on off-road terrain. Thesteerability of the vehicle is considerablyreduced if the wheels lock.
Driving systems
Cruise control
General notes
Cruise control maintains a constant roadspeed for you. It brakes automatically in orderto avoid exceeding the set speed. On long andsteep downhill gradients, especially if the vehi-cle is laden, you must select a low gear ingood time. You need to shift manually usingthe steering wheel paddle shifters beforehand.By doing so, you will make use of the brakingeffect of the engine. This relieves the load onthe brake system and prevents the brakesfrom overheating and wearing too quickly.
When the engine is running, you can use thecruise control lever to limit the speed to anyspeed between 20 mph (30 km/h) and thetechnically permitted maximum speed of thevehicle.
Use cruise control if road and traffic condi-tions make it appropriate to maintain a steadyspeed for a prolonged period.
The speed indicated in the speedometer maydiffer slightly from the speed stored.
Important safety notes
If you fail to adapt your driving style, cruisecontrol can neither reduce the risk of an acci-dent nor override the laws of physics. Cruisecontrol cannot take into account the road,traffic and weather conditions. Cruise controlis only an aid. You are responsible for the dis-tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in yourlane.
Do not use cruise control:
Rin road and traffic conditions which do notallow you to maintain a constant speed, e.g.in heavy traffic or on winding roads
Ron slippery road surfaces. Braking or accel-erating could cause the drive wheels to losetraction and the vehicle could then skid
Rin poor visibility, e.g. due to fog, heavy rainor snow
If there is a change of drivers, advise the newdriver of the speed stored.
Cruise control lever
CActivates or increases speed
DActivates or reduces speed

Parking tips:
ROn narrow roads, drive as close to the park-ing space as possible
RParking spaces that are littered or over-grown might be identified or measuredincorrectly
RParking spaces that are partially occupiedby trailer drawbars might not be identifiedas such or be measured incorrectly
RSnowfall or heavy rain may lead to a parkingspace being measured inaccurately
RPay attention to the warning messages ofParking Assist PARKTRONIC during theparking procedure (Ypage 173).
RYou can intervene in the steering procedureto correct it at any time. Active ParkingAssist will then be canceled
RWhen transporting a load which protrudesfrom your vehicle, you should not use ActiveParking Assist
RNever use Active Parking Assist when snowchains are installed
RMake sure that the tire pressures are alwayscorrect. This has a direct influence on theparking characteristics of the vehicle.
Use Active Parking Assist for parking spaces:
Rthat are parallel or at right-angles to thedirection of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not onthe pavement
Detecting parking spaces
Objects located above the detection range ofActive Parking Assist will not be detectedwhen the parking space is measured. Theseare not taken into account when the parkingprocedure is calculated, e.g. overhangingloads, truck overhangs or loading ramps.Active Parking Assist may therefore guide youinto the parking space too early.
Active Parking Assist does not support youparking in spaces at right angles to the direc-tion of travel if:
Rtwo parking spaces are located directly nextto one another
Rthe parking space is directly next to a lowobstacle such as a low curb
Ryou park forwards
Active Parking Assist does not support youparking in spaces that are parallel or at rightangles to the direction of travel if:
Rthe parking space is on a curb
Rthe system reads the parking space as beingblocked, for example by foliage or grasspaving blocks
Rthe area is too small for the vehicle tomaneuver into
Rthe parking space is bordered by an obsta-cle, e.g. a tree, a post or a trailer
Further information about the detection range(Ypage 172).
GWARNING
If there are objects above the detection
range:
Rthe Parking Package with rear view cam-
era may steer too early
Rthe vehicle may not stop in front of these
objects
This could cause a collision. There is a risk
of an accident.
If objects are located above the detection
range, stop and deactivate the Parking Pack-
age with rear view camera.
