J (Canada only): the red parking brake warning lamp is lit while the vehicle is
in motion.
You are driving with the parking brake applied.
XRelease the parking brake.
The warning lamp goes out and the warning tone ceases.
!N The yellow ABS warning lamp is lit while the engine is running.
ABS (anti-lock braking system) is malfunctioning.
If there is an additional warning tone, the EBD (electronic brake force distribution)
is malfunctioning.
Other driving systems and driving safety systems may also malfunction.
GWARNING
The brake system continues to function normally, but without the functions listed
above. The front and rear wheels could therefore lock if you brake hard, for exam-
ple.
The steerability and braking characteristics may be severely affected. The braking
distance in an emergency braking situation can increase.
If ESP
®is not operational, ESP®is unable to stabilize the vehicle.
There is an increased risk of skidding and an accident.
XObserve the additional display messages in the multifunction display.
XDrive on carefully.
XVisit a qualified specialist workshop immediately.
If the ABS control unit is faulty, there is also a possibility that other systems, such
as the navigation system or the automatic transmission, will not be available.

Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, the
engine can be jump-started from another vehicle or from a donor battery using jumper cables.
Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicle using a donor battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
RJump-starting may be performed only using batteries with a nominal voltage of 12 V.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connected for
a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RWhen the jumper cables are connected to the battery, uninsulated sections of the terminal clamp
do not come into contact with other metal sections.
RThe jumper cables cannot come into contact with parts which can move when the engine is
running, such as the V-belt pulley or the fan.
XApply the parking brake.
XShift the automatic transmission to position j.
XMake sure that the ignition is switched off. All indicator lamps in the instrument cluster must be
off.
XSwitch off all electrical consumers, e.g. rear window defroster, lighting, etc.
XOpen the hood.
Position number Bidentifies the charged battery of the other vehicle or an equivalent jump-starting
device.

for the direction of travel flash. After resetting
the combination switch, the hazard warning
lamp starts flashing again.
iThe automatic transmission can only
change gear when the battery has sufficient
charge.
If you cannot shift the automatic transmission
to position i, the propeller shafts to the
driven axles must be removed.
Transporting the vehicle
!When the vehicle is loaded for transport, the
front and rear axles must be stationary and on the same transportation vehicle. Positioning
over the connection point of the transport
vehicle is not permitted. The drive train may
otherwise be damaged.
!You may only secure the vehicle by the
wheels, not by parts of the vehicle such as
axle or steering components. Otherwise, the
vehicle could be damaged. The towing eyes can be used to pull the vehicle
onto a trailer or transporter if you wish to trans-
port it.
XTurn the SmartKey to position 2in the igni-
tion lock.
XShift the transfer case to position Neutral

XSecure the vehicle.
Recovering a vehicle that has become
stuck
!
When recovering a vehicle that has become
stuck, pull it as smoothly and evenly as pos-
sible. Excessive tractive power could damage
the vehicles.
If the drive wheels have become stuck in loose
or muddy ground, pull the vehicle out with
extreme caution, especially so if the vehicle is
loaded.
Never attempt to recover a stuck vehicle with a
trailer attached.
Pull out the vehicle backwards, if possible using the tracks it made when it became stuck.
Towing in the event of malfunctions
General notes
!If you are removing the propeller shaft, use
M10 nuts as spacers on the M8 bolts and
secure them with M8 nuts.
New self-locking nuts must be used when the
propeller shafts are refitted.
It is important that you observe the safety
instructions when towing away your vehicle
(
Ypage 251).
