2019 MERCEDES-BENZ GLA tire pressure

Bear in mind that at a speed of only 30 mph(approximately 50 km/h), the vehicle covers adistance of 44 ft (approximately 14 m) persecond.
Drive sensibly – save fuel
Observe the following tips to save fuel:
RThe tires should always be inflated to therecommended tire pressure.
RRemove unnecessary loads.
RRemove roof racks when they are not nee-ded.
RWarm up the engine at low engine speeds.
RAvoid frequent acceleration or braking.
RHave all maintenance work carried out asindicated by the service intervals in theMaintenance Booklet or by the service inter-val display.
Fuel consumption also increases when drivingin cold weather, in stop-start traffic and in hillyterrain.
Drinking and driving
GWARNING
Drinking and driving and/or taking drugs
and driving are very dangerous combina-
tions. Even a small amount of alcohol or
drugs can affect your reflexes, perceptions
and judgment.
The possibility of a serious or even fatal
accident 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
taking drugs.
Emission control
GDANGER
Combustion engines emit poisonous
exhaust gases such as carbon monoxide.
Inhaling these exhaust gases is hazardous to
health and can result in poisoning. There is a
risk of fatal injury. Therefore, never leave the
engine running an enclosed space without
adequate ventilation.
Certain engine systems are designed to keepthe level of poisonous components in exhaustfumes within legal limits.
These systems only work at peak efficiency ifthey are serviced exactly in accordance withthe manufacturer's specifications. Always havework on the engine carried out at a qualifiedspecialist workshop. Mercedes-Benz recom-mends that you use an authorized Mercedes-Benz Center for this purpose. In particular,work relevant to safety or on safety-relatedsystems must be carried out at a qualified spe-cialist workshop.
The engine settings must not be changedunder any circumstances. Furthermore, allspecific service work must be carried out atregular intervals and in accordance with theMercedes-Benz service requirements. Detailscan be found in the Maintenance Booklet.
ECO display
The ECO display shows you how economicalyour driving style is. The ECO display assistsyou in achieving the most economical drivingstyle for the selected settings and prevailingconditions. Your driving style can significantlyinfluence the vehicle's consumption.
CAcceleration
DCoasting

RDrive slowly and evenly, if necessary at awalking pace.
REnsure that the wheels are in contact withthe ground at all times.
RDrive with extreme care on unfamiliar off-road routes where visibility is poor. Forsafety reasons, get out of the vehicle firstand survey the off-road route.
RCheck the depth of water before fording riv-ers and streams.
RWatch out for obstacles.
RTake care when turning on an uphill ordownhill slope or when driving across aslope. The vehicle could otherwise tip over.
RAlways keep the side windows and the pan-orama roof with power tilt/sliding panelclosed during the journey.
RDo not deviate from marked routes.
RDo not use the HOLD function when drivingoff-road, on steep uphill or downhill gradi-ents or on slippery or loose surfaces. TheHOLD function cannot hold the vehicle onsuch surfaces.
Checklist before driving off-road
XEngine oil level:check the engine oil leveland add oil if necessary.
When driving on steep gradients, the engineoil level must be sufficiently high to ensure acorrect oil supply in the vehicle.
XWheels and tires:check the tire treaddepth and tire pressure.
XCheck for damage and remove any foreignobjects, e.g. small stones, from the wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in aloss of tire pressure and damage the tirebead. Before driving off-road, check thewheels and replace them if necessary.
Checklist after driving off-road
!If you detect damage to the vehicle afterdriving off-road, have the vehicle checkedimmediately at a qualified specialist work-shop.
XDeactivate off-road program (Ypage 132).
XDeactivate DSR (Ypage 169).
XClean the headlamps and rear lights andcheck for damage.
XClean the front and rear license plates.
XClean the wheels and tires with a water jetand remove any foreign objects.
XClean the wheels, wheel housings and thevehicle underside with a water jet; check forany foreign objects and damage.
XCheck whether twigs or other parts of plantshave become trapped. These increase therisk of fire and can damage fuel pipes, brakehoses or the air bellows of the axle jointsand propeller shafts.
XAfter the trip, examine without fail the entireundercarriage, wheels, tires, brakes, body-work structure, steering, chassis andexhaust system for damage.
XAfter driving in sand, mud, gravel, water orsimilar dirty conditions, have the followingchecked and cleaned:
Rbrake discs
Rwheels
Rbrake pads
Raxle joints
XIf you detect strong vibrations after off-roadtravel, check for foreign objects in thewheels and drive train and remove them ifnecessary. Foreign objects can disturb thebalance and cause vibrations.
Driving over poor road surfaces places greaterdemands on your vehicle than driving on nor-mal roads. After driving off-road, check thevehicle. This allows you to detect damagepromptly and reduce the risk of an accident toyourself and other road users.
Driving on sand
Observe the following rules when driving onsand:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.
RUse the left-hand steering wheel paddleshifter to shift to a lower gear appropriate tothe terrain.
Drivingtips155
Driving an d parking
Z

RDrive quickly to overcome the rolling resist-ance. Otherwise the vehicle's wheels couldbecome stuck in loose ground.
RDrive in the tracks of other vehicles if possi-ble. Make sure that:
-the tire ruts are not too deep.
-the sand is sufficiently firm.
-the ground clearance of the vehicle is suf-ficient.
Tire ruts and gravel roads
!Check that the ruts are not too deep andthat your vehicle has sufficient clearance.Otherwise, your vehicle could be damagedor bottom out and get stuck.
Observe the following rules when driving alongruts in off-road terrain or on roads with loosegravel:
RActivate the off-road program (Ypage 132).
RAvoid high engine speeds.
RShift to a lower gear using the left-handsteering wheel paddle shifter.
RDrive slowly.
RWhere ruts are too deep, drive with thewheels of one side on the center grassyarea, if possible.
Traveling uphill
Approach/departure angle
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.
RObserve the warnings for off-road driving(Ypage 153).
RFollow the line of fall when driving on slopesand steep inclines.
RBefore driving on extreme uphill and down-hill gradients, select the off-road program(Ypage 132).
RDrive slowly.
RAccelerate gently and make sure that thewheels are gripping.
RAvoid high engine speeds, except when driv-ing on sandy and muddy routes with highdriving resistance.
RUse the left-hand steering wheel paddleshifter to shift to a lower gear appropriate tothe gradient.
RUse the left-hand steering wheel paddleshifter to shift into a lower gear in good timeon long and steep downhill gradients.
Hill start assist will aid you when pulling awayon a hill. For further information about hillstart assist, see (Ypage 128).
Do not shift into transmission position\\when driving off-road. You could lose controlof the vehicle if you attempt to brake the vehi-cle using the service brake. If the gradient istoo steep for your vehicle, drive back down inreverse gear.
Always observe the approach/departure anglevalues (Ypage 340).
Maximum gradient-climbing capability
Always observe the maximum gradient climb-ing ability values (Ypage 340).
Hilltops
When driving up an uphill gradient, slightlyreduce pressure on the accelerator immedi-ately before reaching the brow of the hill.Make use of the vehicle's own impetus totravel over the brow.
This style of driving prevents:
Rthe vehicle from lifting off the ground on thebrow of a hill
Rthe vehicle from traveling too quickly downthe other side
Driving downhill
RDrive slowly.
RDo not drive at an angle down steepinclines. Steer into the line of fall and drivewith the front wheels aligned straight. Oth-erwise, the vehicle could slip sideways, tipand rollover.
RShift to a lower gear using the left-handsteering wheel paddle shifter before tacklingsteep downhill gradients.

AMG vehicles)
Important safety notes
GWARNING
If you use start-off assist, individual wheels
may start to spin and the vehicle may skid. If
ESP®is deactivated, there is a greater dan-
ger of skidding and having an accident.
Make sure that no persons or obstacles are
in the vicinity of the vehicle.
Start-off assist enables optimum accelerationfrom a standstill. For this, a suitably high-griproad surface is required and the vehicle andtires must be in good working order.
Do not activate start-off assist on public roads.
Observe the safety notes on driving safety sys-tems (Ypage 60).
Be sure to read the safety notes and informa-
tion on ESP®(Ypage 63).

Driving and pa rking

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.
