Emergency situations
General
This chapter is intended for trained emergency crews and working
pe rsonnel who have the necessary tools and equ ipment to perform
these operations. •
Starting by pushing or towing
(D Note
Vehicles with an automatic transmis sion cannot be started by
push ing or towing . •
Starting with jumper cables
Ju mpe r cabl e: Note the man ufa ct ure r's in for matio n.
If the battery is discharged, another veh icle can provide starting
assistance. For this you require a jumper cable. Both batteries must
h ave t he same vo ltage (V) and a s im ilar capacity (Ah).
Jumper cables
Use
only jumper cables of sufficiently large cross section to safely
car ry the starter current . Refer to the manufactu rer's specifications.
Use only j um per ca bles with
isolated term in al cl am ps and pr operly
marked for distinction :
plus
(+) cable in mo st c ases c olored red
minus( -) cable i n most cas es co lor ed black .
& WARNING
Batteries contain electricity, acid , and gas. Any of the se can cause
very ser ious or fatal injury . Follow the instructions below for safe
handling of your vehicle 's battery .
• Always shield your eyes and avoid leaning over the battery
whenever possible .
• A discharged battery can already freeze at temperatures just
below 32 °F (0 °C l. Never attempt to provide starting assistance on
a frozen or thawed out battery- Danger of explosion and chemical
burns! Replace a battery if it has been frozen.
• Do not allow battery acid to contact eyes or skin. Flush any
contacted area with water immediately .
• Improper use of a booster battery to start a vehicle may cause
an explosion .
• Vehicle batteries generate explosive gases . Keep sparks, flame
and lighted cigarettes away from batteries .
• Do not try to jump start any vehicle with a low acid level in the
battery .
• The voltage of the booster battery must also have a 12 -Volt
rating . The capacity (Ah ) of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
different voltage or substantially different "Ah " rating may cause
an explosion and personal injury .
• Never charge a frozen battery . Gas trapped in the ice may cause
an explosion.
• Never charge or use a battery that has been frozen . The battery
case may have be weakened .
• Use of batter ies of different voltage or substantially different
capacity (Ah) rating may cau se an e xplosion and inju ry . The
c apacity (Ah ) of the booster battery should not be lower than that
of the discharged battery. .,.

bumper: removing the
cover cap
Fig . 207 Front
bumper: screwing in
the towing loop
The towing loop fits into the threaded hole located on the
right side of the front bumper and covered by a small cover
when not in use. Note that the towing loop has a
left-hand
thread!
- Remove the towing loop from the vehicle toolkit
=>
page 270.
- Press on the bottom edge of the cover cap to disengage
and take it out of the bumper. The cap remains
connected to the bumper=> fig. 206. - Insert the
towing loop into the threaded hole => fig. 207
and turn it all the way in until it is seated securely, then
tighten it with the wheel bolt wrench.
When it is no longer needed, unscrew the towing loop and put it
back into the on-board toolkit. Make sure to have the towing loop
stored in the vehicle at all times.
& WARNING
If the towing loop is not screwed in as far as it will go, the thread
can pull out when the vehicle is towed -potential risk of an
accident. •
Rear towing loop
Do not install the rear towing loop until it is needed.

Lifting the vehicle
Important safety precautions
Be aware of the following hazards before lifting the vehicle with a
workshop hoist or floor jack:
• The vehicle should never be lifted or jacked up from underneath
the engine oil pan, the transmission housing, the front or rear axle
or the body side members. This could lead to serious damage.
• Use lifting equipment with padded contact surfaces to avoid
damage to the underbody or chassis frame.
• Alternatively, cover the contact surfaces on workshop hoist or
floor jack with rubber pads before lifting .
• Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist .
• Before driving over a workshop hoist, ensure that there is suffi­
cient clearance between the hoist and low parts of the vehicle .
& WARNING
To reduce the risk of serious injury and vehicle damage:
• Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=> fig. 211 and=> fig. 212 .
• Failure to lift the vehicle at these points could cause the vehicle
to tilt or fall from a lift if there is a change in vehicle weight distri­
bution and balance. This might happen, for example, when heavy
components such as the engine block or transmission are
removed .
• When removing such heavy components, anchor vehicle to
hoist or add corresponding weights to maintain the center of
gravity . Otherwise , the vehicle might tilt or slip off the hoist,
causing serious personal injury. •
Lifting with workshop hoist and with floor
jack
The vehicle may only be lifted at the lifting points illus­
trated.
