MERCEDES-BENZ GLA SUV 2022 Owners Manual

Please also observe the following running-in
no
tes:
= In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven aser the vehicle
has been delivered or aser repairs. Full sys-
tem eMectiveness is not reached until the end
of this teach-in process.
= Brake pads, brake discs and tyres that are
either new or have been replaced only achieve
optimum braking eMect and grip aser several
hundred kilometres of driving. Compensate for
the reduced braking eMect by applying greater
force to the brake pedal. Notes on driving
&
WARNING Risk of accident due t
o objects
in the driver's footwell
Objects in the driver's footwell may impede
pedal tr
avel or block a depressed pedal.
This jeopardises the operating and road safety
of the vehicle. 
Stow all objects in the vehicle securely
so t
hat they cannot get into the driver's
footwell. 
Always Nt t
he Ooor mats securely and as
prescribed in order to ensure that there
is always suPcient room for the pedals. 
Do not use loose Ooor mats and do no
t
place Ooor mats on top of one another. &
WARNING Risk of accident due t
o incor-
rect footwear
Incorrect footwear includes, for example: = shoes wit

h platform soles
= shoes with high heels
= slippers
There is a risk of an accident. 
Always wear suitable footwear so that
y

ou can operate the pedals safely. &
WARNING Risk of accident if t
he vehicle is
switched oM while driving
If you switch oM t
he vehicle while driving,
safety functions are restricted or no longer
available.
This may aMect the power steering system and
the brake force boosting, for example.
You will need to use considerably more force
to steer and brake, for example. 
Do not switch oM t
he vehicle while driv-
ing. &
DANGER Risk of f
atal injuries due to
exhaust gases
Combustion engines emit poisonous exhaust
g
ases such as carbon monoxide. Breathing in
these exhaust gases is hazardous to health
and results in poisoning. 
Never leave the engine and, if present,
t

he stationary heater, running in an
enclosed space without suPcient venti-
lation. 178
Driving and parking

&
WARNING Risk of skidding and of an acci-
dent due t o shising down on slippery road
surfaces
If you shis do
wn on slippery road surfaces to
increase the engine braking eMect, the drive
wheels may lose traction. 
Do not shis do
wn on slippery road surfa-
ces to increase the engine braking
eMect. &
DANGER Risk of f
atal injury due to poison-
ous exhaust gases
If the tailpipe is blocked or suPcient v
entila-
tion is not possible, poisonous exhaust gases
such as carbon monoxide may enter the vehi-
cle. This is the case, for example, if the vehicle
gets stuck in the snow. 
Keep the tailpipe and the area around
t

he vehicle free from snow when the
engine or the stationary heater is run-
ning. 
Open a window on the side of the vehicle
f

acing away from the wind to ensure an
adequate supply of fresh air. &
WARNING Risk of accident due t
o the
brake system overheating
If you leave your foot on the brake pedal when
dr
iving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail. 
Never use the brake pedal as a footrest. 
Do not depress the brake pedal and the
acceler
ator pedal at the same time while
driving. *
NOTE Engine damag
e due to excessively
high engine speeds The engine will be damaged if you drive with
t

he engine in the overrevving range. 
Do not drive with the engine in the over-
r
evving range. *
NOTE Causing w
ear to the brake linings by
permanently depressing the brake pedal 
Do not permanently depress the brake
pedal while dr

iving. 
To use braking eMect of t
he engine, shis
to a lower gear in good time. *
NOTE Damag
e to the drivetrain and
engine when pulling away 
Do not warm up the engine while the
v

ehicle is stationary. Pull away immedi-
ately. 
Avoid high engine speeds and driving at
full t

hrottle until the engine has reached
its operating temperature. *
NOTE Damag
e to the catalytic converter
due to non-combusted fuel The engine is not running smoothly and is mis-
Nr

ing.
Non-combusted fuel may get into the catalytic
converter. Driving and parking
179


Only depress the accelerator pedal
slightl
y. 
Have the cause r
ectiNed immediately at
a qualiNed specialist workshop. *
NOTE R
educed battery life due to frequent
short-distance trips The 12 V battery may not be
suPcientl
y
charged when the vehicle is used only for
short-distance trips. This reduces the life of
the battery. 
Drive longer distances regularly to
c

harge the battery. *
NOTE Damag
e to the vehicle due to not
observing the maximum permitted head-
room clearance If the vehicle height is greater than the maxi-
mum per
mitted headroom clearance, the roof
and other parts of the vehicle may be dam-
aged. 
Observe the signposted headroom clear-
ance. 
If the vehicle height is greater than the
per
mitted headroom clearance, do not
enter. 
Observe the changed vehicle height with
add-on r
oof equipment. Notes on driving with a roof load, trailer or fully
laden v
ehicle
When driving with a loaded roof luggage rack or
trailer as well as with a fully laden or fully occu-
pied vehicle, the vehicle's driving and steering
characteristics change.
You should bear the following in mind:
= Do not exceed the permissible roof load and
towing capacity. Also observe the technical
data in the printed Owner's Manual.
= Evenly distribute the roof load, and place
heavy objects at the bottom. Also comply with
the notes on loading the vehicle
( page 122). =
Dr
ive attentively, and avoid suddenly pulling
away, braking and steering as well as rapid
cornering.
Notes on driving on salt-treated roads
The braking eMect is limited on salt-treated roads.
Therefore, observe the following notes: = due to salt build-up on the brake disks and
brakepads, the braking distance can increase
considerably or result in braking only on one
side
= maintain a much greater safe distance to the
vehicle in front
To remove salt build-up: = brake occasionally while paying attention to
the traPc conditions
= carefully depress the brake pedal at the end of
the journey and when starting the next jour-
ney
Notes on aquaplaning
Aquaplaning can take place once a certain
amount of water has accumulated on the road
surface. 180
Driving and parking

Observe the following notes during heavy precipi-
t
ation or in conditions in which aquaplaning may
occur:
= reduce speed
= avoid tyre ruts
= avoid sudden steering movements
= brake carefully
% Also observe the notes on regularly checking
wheels and tyr

es ( page 387).
Notes on driving through water on the road sur-
f
ace
Water which has entered into the vehicle can
damage the engine, electrics and transmission.
Water can also enter the air intake of the engine
and cause engine damage.
Observe the following if you must drive through
water:
= The water, when calm, may only reach the
lower edge of the vehicle body.
= Drive at a maximum speed of 10 km/h; water
can otherwise enter the vehicle interior or
engine compartment. =
V
ehicles travelling in front, or oncoming vehi-
cles, can create waves which may exceed the
maximum permissible depth of the water.
The braking eMect of the brakes is reduced aser
fording. Brake carefully while paying attention to
the traPc conditions until braking power has been
fully restored. Notes on
oM-r
oad driving &
WARNING Risk of accident if y
ou do not
keep to line of fall on inclines
If you drive at an angle or turn on an incline,
t
he vehicle could slip sideways, tip and roll-
over. 
Always drive on inclines in the line of fall
(s

traight up or down) and do not turn. &
WARNING Risk of Nr
e due to Oammable
material coming into contact with hot
parts of the exhaust system
If combustible materials, e.g. leaves, grass or
twigs, come int
o contact with hot parts of the
exhaust system, they may ignite. 
When driving oM-r
oad or on unpaved sur-
faces, check the underside of the vehicle
at regular intervals. 
In particular, remove any trapped parts
of plants or o
ther Oammable material. 
If damage should occur, immediately
inf
orm a qualiNed specialist workshop. When driving oM-r

oad, sand, mud and water or
water mixed with oil, etc., may get into the brakes.
This may lead to a reduction in braking eMect or
total brake failure as a result of increased wear.
The braking characteristics will vary depending on
the material that has entered the system. Clean
the brakes aser driving oM-road. If you then notice
reduced braking eMect or hear scraping noises,
have the brake system checked at a qualiNed spe- Driving and parking

Function of the regenerative brake system
Depending on t
he selected recuperation level, the
electric motor is operated as an alternator when
in overrun mode and during braking in order to
charge the high-voltage battery while driving. As
soon as you take your foot oM the accelerator
pedal when the vehicle is in motion and in trans-
mission position h, recuperation in overrun
mode is initiated.
The higher the recuperation, the more sharply the
vehicle is braked when coasting and the more
electrical energy is fed into the high-voltage bat-
tery.
The deceleration in overrun mode may not be suf-
ficient depending on the driving conditions.
Decelerating to a standstill is not possible. Also
brake with the service brake if necessary. Always
adapt your speed to the driving conditions and
keep a suPcient distance. The recuperative brake system has the following
c

haracteristics:
= supports braking with electronically controlled
brake force boosting
= converts the kinetic energy of the vehicle into
electric energy
% If you brake hard, the mechanical brake is
also used. This means t
hat the maximum
recuperative energy cannot be recovered. The
more you drive and brake in an anticipatory
manner, the more ePciently energy can be
recuperated.
System limits
The br
aking eMect of the electric motor during
recuperation in overrun mode may be reduced or
may not be available at all in the following situa-
tions:
= when the high-voltage battery charge level
increases
= if the high-voltage battery is not yet at a nor-
mal operating temperature In these cases, the desired deceleration is set by
t

he brake control system.
Manually setting recuperative deceleration
% In the Î dr
ive program, you can use the
steering wheel gearshis paddles to manually
adjust the intensity of recuperation in overrun
mode. %
When the vehicle is started again or transmis-
sion position h is eng

aged again, the stand-
ard setting is automatically set. 186
Driving and parking

The following recuperation levels are available:
= hX Int
elligent, anticipatory recuperation
with ECO Assist (standard setting)
( page 187)
= hq No recuperation: the vehicle rolls freely
= h Normal recuperation
= hX Increased recuperation: strong deceler-
ation in overrun mode, e.g. for driving on
downhill gradients
= hXX Maximum recuperation: maximum
deceleration in overrun mode 
To increase recuperation: br
ieOy pull gearshis
paddle 1. 
To reduce recuperation: br
ieOy pull gearshis
paddle 2. 
Standard setting: pull and hold g
earshis pad-
dle 1 or 2 or engage transmission position
h again. The Instrument Display shows currently set recu-
per

ation level 1, for example, hX. Eco Assist function (plug-in hybrid)
%
The following function is country-dependent
and a

vailable only in conjunction with an inte-
grated hard drive navigation system.
ECO Assist is active only in drive programs A,
Î, Ï and , and onl

y in transmission
positions h or hX. Permanent manual gear-
shising p must be switched oM ( page 196).
ECO Assist analyses data for the vehicle's expec-
ted route. This allows the system to optimally adjust the driving style for the route ahead, save
fuel and r
ecuperate.
