Driving tips General driving tips
Drive carefully and maintain a suitable distance from the vehicle in front. Avoid frequent and
sudden acceleration as well as abrupt braking.
During partial electric drive, pulling away and
acceleration, the electric motor supports the
internal combustion engine.
During overrun in transmission position Dand
braking, the electric motor operates as an alter-
nator.
Further information on the ECO start/stop func-
tion (Y page 269).
Additional driving tips (Y page 194).
Stationary vehicle
If the vehicle is stopped, the combustion engine is, for the most part, switched off. Automatic
climate control continues to function. The elec-
tro-mechanically assisted steering gear allows
use of the power steering without loss of com-
fort. Acceleration
Depending on the operating mode, pulling away and driving under low load conditions are per-
formed:
R entirely by electric propulsion
R in combination with the internal combustion
engine
When accelerating rapidly under increased or
full load, increased boost mode is utilised. The
electric motor supports the combustion engine
by providing additional drive torque.
Overrun mode or braking There are three possible operating modes when
the hybrid vehicle is decelerating:
R When coasting and decelerating, energy recu-
peration is already taking place (Y page 259).
The electric motor functions as an alternator
and stores the recuperated energy in the
high-voltage battery.
R When braking gently, the electric motor
increases the deceleration of the vehicle.
Energy recuperation is increased
(Y page 259). The electric motor functions as
an alternator and stores the recuperated
energy in the high-voltage battery.
R During heavy braking, the service brake is
also used to slow down the vehicle. Both sys-
tems work together.
Driving in the city In urban traffic, energy is recuperated during
frequent deceleration phases.
The vehicle is driven by the electric motor alone
only when all conditions for the automatic
engine switch-off are fulfilled.
Further information on the automatic engine
switch-off (Y page 269).
Driving on inter-urban roads The following phases are possible when driving
on inter-urban roads:
R rapid acceleration (boost mode)
R energy recuperation
R electric operation mode
The vehicle can be driven by the electric motor
alone up to a speed of approximately 120 km/h.
Depending on the characteristics of the route,
there may be a lot of recuperated energy avail-
able. This reduces consumption and emissions. 268

Always use wheel bolts
;to fit the collaps-
ible emergency spare wheel. Using other
wheel bolts to fit the collapsible emergency
spare wheel could damage the brake system. :

Clean the wheel and wheel hub contact sur-
faces.
X Slide the wheel to be mounted onto the cen-
tring pin and push it on.
X Tighten the wheel bolts until they are finger-
tight.
X Unscrew the centring pin.
X Tighten the last wheel bolt until it is finger-
tight.
X Mercedes-AMG vehicles with a collapsi-

WARNING
The wheels could work loose if the wheel nuts and bolts are not tightened to the specified
tightening torque. There is a risk of accident.
Have the tightening torque immediately
checked at a qualified specialist workshop
after a wheel is changed.
! Mercedes-AMG vehicles with a collapsi-
ble emergency spare wheel: inflate the col-
lapsible emergency spare wheel using the
tyre inflation compressor before lowering the vehicle. There is otherwise a risk of damaging
the wheel.
X Place the ratchet ring spanner onto the hex-
agon nut of the jack so that the letters ABare
visible.
X Turn the ratchet ring spanner until the vehicle
is once again standing firmly on the ground.
X Place the jack to one side. X
Tighten the wheel bolts evenly in a crosswise
pattern in the sequence indicated (: toA).
The tightening torque must be 150 Nm.
X Turn the jack back to its initial position.
X Stow the jack and the rest of the tyre chang-
ing tools in the stowage well under the boot
floor.
X Check the air pressure of the newly fitted
wheel and adjust accordingly.
Observe the recommended tyre pressure
(Y page 408).
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning sys-
tem or the tyre pressure monitor cannot func-
tion reliably. Only restart the tyre pressure loss
warning system or tyre pressure monitor when Changing a wheel

Vehicles with the Off-Road Engineering
package: the maximum gradient climbing abil-
ity is 100 %when the LOW RANGE off-road gear
is selected.
Mercedes-AMG vehicles: the maximum gradi-
ent climbing ability is 80 %.
Vehicles without the Off-Road Engineering
package: the maximum gradient climbing abil-
ity is 80 %.
GLE 550 e 4MATIC: the maximum gradient
climbing ability is 50 %.
Carefully depress the accelerator pedal and
make sure that the wheels do not spin when
driving on steep terrain.
i If the load on the front axle is reduced when
pulling away on a steep uphill slope, the front
wheels have a tendency to spin. 4ETS recog-
nises this and brakes the wheels accordingly. The rear wheel torque is increased and it is
easier to pull away.

ent-climbing capability, see (Y page 202).Trailer tow hitch
