2015 MERCEDES-BENZ G-Class manual transmission

Shift ranges
Introduction When the automatic transmission is in posi-
tion
D, it is possible to restrict or derestrict
the shift range.
The shift range selected is shown in the mul- tifunction display. The automatic transmis-
sion shifts only as far as the selected gear.
Setting the shift range is not possible on AMG
vehicles.
Driving situations =
You can use the engine's braking
effect
5
The braking effect of the engine can
be utilized on downhill gradients or
when driving:
R on steep mountain roads
R in mountainous terrain
R in arduous conditions 4
The braking effect of the engine can
be utilized on extremely steep
downhill gradients and long down-
hill stretches. Restricting the shift range
X
Pull the left-hand steering wheel paddle
shifter (Y page 144).
The automatic transmission shifts down
one gear and restricts the shift range to the
relevant gear.
i If the engine exceeds the maximum
engine speed when shifting down, the auto- matic transmission protects against engine
damage by not shifting down.
i If the maximum engine speed for the shift
range is reached and you continue to accel- erate, the automatic transmission shifts upin order to prevent the engine from over-
revving, even if the shift range is restricted. Derestricting the shift range X
Pull the right-hand steering wheel paddle
shifter (Y page 144).
The automatic transmission shifts up one
gear and restricts the shift range to the rel-
evant gear.
Clearing the shift range restriction X
Pull and hold the right-hand steering wheel
paddle shifter (Y page 144) untilDis shown
again in the multifunction display.
The automatic transmission shifts from the
current shift range directly to D.
Selecting the ideal shift range X
Pull the left-hand steering wheel paddle
shifter (Y page 144) and hold it in position.
The automatic transmission shifts to the
gear which allows optimum acceleration
and deceleration. To do this, the automatic transmission shifts down one or more
gears.
i The automatic transmission cannot shift
down beyond second gear. To shift to first
gear, you have to pull the left steering
wheel paddle shifter. Manual drive program
General information The manual drive program is only available on
AMG vehicles. In manual drive program M,
you can permanently change gear yourself by using the steering wheel paddle shifters. The
transmission must be in position D. The gear
currently selected and engaged is shown in
the multifunction display.
Manual drive program Mdiffers from drive
programs Eand Swith regard to spontaneity,
responsiveness and smoothness of gear

Upshifting !
In manual drive program
M, the automatic
transmission does not shift up automati-
cally even when the engine limiting speed
for the current gear is reached. When the
engine limiting speed is reached, the fuel
supply is cut to prevent the engine from
overrevving. Always make sure that the
engine speed does not reach the red area of
the tachometer. There is otherwise a risk of
engine damage. X
If corresponding gearshift recommenda-
tion :appears in the multifunction display

You should have all work involving the
battery carried out at a qualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery yourself, make sure that:
R you switch off the engine and remove the
SmartKey. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, electronic components, such
as the alternator, may be damaged.
R you first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R on vehicles with automatic transmission,
the transmission is locked in position P
after disconnecting the battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The battery and the cover of the positive
terminal clamp must be installed securely
during operation. H
Environmental note Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment. Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified spe-
cialist workshop or a special
collection point for used bat-
teries.
In order for the battery to achieve the maxi-
mum possible service life, it must always be
sufficiently charged.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks. Battery acid is caustic.
Avoid contact with skin, eyes or
clothing.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery discon-
nected at a qualified specialist workshop. You can also charge the battery with a charger
recommended by Mercedes-Benz. Contact a
qualified specialist workshop for further infor-
mation.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehi-
cle occupants from suffering acid burns
should the battery be damaged in the event of an accident.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for a lengthy period. Consult a qualified spe-
cialist workshop if you wish to leave your
vehicle parked for a long period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very 294
