The transmission has
problems shifting gear.The transmission is losing oil.
XHave the transmission checked ataqualified specialist workshop
immediately.
The acceleration ability
is deteriorating.
The transmission no lon-
ger changes gear.The transmission is in emergency mode.
It is only possible to shift into secondgear and reverse gear.
XStop the vehicle.
XShift the transmission to position P.
XSwitch off the engine.
XWait at least ten seconds before restarting the engine.
XShift the transmission to positionDor R.
If D is selected, the transmission shifts into secondgear; ifRis
selected, the transmission shifts into reverse gear.
XHave the transmission checked at aqualified specialist workshop
immediately.
Transfer case
This section is only valid for vehicles with 4-
wheel drive (4MATIC). Power is always trans-
mitted to both axles.
!Performancet ests may only be carried out
on a2 -axle dynamometer. The brake system
or transfer case could otherwise be damaged. Contact aqualified specialist workshop for a
performancet est.
!Since ESP®engages automatically, the igni-
tion must be switched off (the SmartKey or
Start/Stop button must be in position 0or 1)
if:
Rthe electric parking brake is being tested
on abrake dynamometer
Rthe vehicle is being towed with only one
axle raised (not permitted for vehicles with
4MATIC).
The brake system could otherwise be dam-
aged.
!Vehicles with 4MATIC must not be towed
with either the front or the rear axle raised, as doing so will damage the transmission.
