Emergency situations
General
This chapter is intended for trained emergency crew s and working
personnel who have the necessary tools and equipment to perform
these operations. •
Starting by pushing or towing
0 Note
Vehicles with an automatic tran smission cannot be started by
push ing o r towing . •
Starting with jumper cables
If n ece ssa ry, th e engin e ca n be sta rte d by conne cti ng it to
the battery of another veh ic le .
If the engin e should fai l to start because of a discharge d or weak
b at te ry, the batt ery can be con nected t o the batt er y of
another
ve hic le, using a pair of jumper cables to start the engine.
Jumper cables
Use
only jumper cables of suffici ently large cross section to safely
c arry the st ar ter curre nt. Refer to th e m anuf actu rer's sp ec ificati ons.
Use on ly j umper ca bles with
isolated termi na l clam ps and properly
marked fo r distinct ion :
plus (+l cable in mo st c ases c olor ed red
minus (-l cable in most cases colored black.
& WARNING
Batteries contain electricity , acid, and gas. Any of these can cause
very serious 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). Before connecting a jumper cable, the frozen
battery must be thawed completely, otherwise it could explode.
• 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 e xplosive 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 (Ahl of the booster battery should not be
lower than that of the discharged battery . Use of batteries of
diffe rent voltage or substantially different "Ah " rating may cause
an explosion and personal injury .
• Never charge a frozen battery. Gas trapped in the ice may cau se
an explosion .
• Never charge or use a battery that has been frozen . The battery
case may have be weakened.
• Use of batteries of different voltage or substantially different
capacity (Ah ) rating may cause an explosion and injury . The
capacity (Ahl of the booster battery should not be lower than that of the discharged battery . ...

& WARNING (continued)
• Before you check anything in the engine compartment, always
read and heed all WARNINGS~ page 242, "Engine compartment".
0 Note
• Applying a higher voltage booster battery will cause expensive
damage to sensitive electronic components, such as control units,
relays, radio, etc .
• There must be no electrical contact between the vehicles as
otherwise current could already start to flow as soon as the positive
(+) terminals are connected.
[ i] Tips
The discharged battery must be properly connected to the vehicle's
electrical system. •
Use of jumper cables
Make sure to connect the jumper cable clamps in exactly
the order described below!

Vehicle with discharged battery:
- Turn off lights and accessories, move lever of automatic
transmission to
N (Neutral) or P (Park) and set parking
brake.
Connect POSITIVE (+) to POSITIVE (+) (red)
1. Connect clamp of plus cable to positive(+) terminal G)
~ fig. 225 of discharged vehicle battery@.
2. Connect clamp on opposite end of cable to positive(+)
terminal
® of booster battery@.
Connect NEGATIVE (-) to NEGATIVE (-) (black)
3. Connect clamp of minus cable (black) to negative( -)
terminal
0 of booster battery@.
4. Connect clamp on opposite end of negative cable to the
negative( -) terminal © of the discharged vehicle battery
@.
- Check that all screw plugs on the battery cells are
screwed in firmly. If not, tighten plugs prior to
connecting clamp on negative battery terminal.
Starting the engine
- Start the engine of the vehicle with the booster battery.
Run the engine at a moderate speed.
- Start engine with discharged vehicle battery in the usual
manner.
- If the engine fails to start: do not keep the starter
cranking for longer than 10 seconds. Wait for about 30
seconds and then try again. .,,.

bumper: removing the
cover cap
Fig . 227 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 cap
when not in use. -
Remove the towing loop from the vehicle tools
=> page 290.
-Press on the bottom edge of the cover cap to disengage
it from the bumper. The cap remains connected to the
bumper => fig. 226.
- Screw the towing loop into the threaded hole as far as it
will go
=> fig. 227, then tighten it with the wheel bolt
wrench.
When it is no longer needed , unscrew the towing loop and put it
back into the onboard 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. •

If you must lift your vehicle with a floor jack to work underneath , be
sure the vehicle is safely supported on stands intended for this
purpose .
Fr ont lifting point
The lifting poi nt is located on the floo r pan rei nforceme nt about at
the same leve l as the jack mounting point~ page
308, fig. 230. Do
not lift the vehicle at the vertical sill reinforcement.
Rear lifting point
The li ftin g point is locate d on t he vert ical re inforceme nt of th e low er
sil l for the on board jack~ page

Lifting with vehi cle ja ck
Refer to
~ page 296.
& WARNING
• To reduce the ri sk of serious injury and vehicle damage.
- Always l ift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
~ page 308 , fig. 230 and
~ page 308, fig. 231.
- 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 distribution and balan ce . This might happen , for
e xample , when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add correspond ing we ights to maintain the center of
gravity. Otherwise , the vehicle might tilt or slip off the hoist ,
causing ser ious personal injury .
0 Note
• Be aware of the fo llowing po ints be fore l ifting the ve hicle:
- The vehicle should never be lifted o r ja cked up from under ­
neath the engine oil pan , the tran smis sion housing , the front or
rear a xle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame , a rubber
pad must be inserted between the floor jack and the lift points .
- Before dr iving over a workshop hoist , check that the vehicle
weight does not exceed the permis sible lifting capacity of the
hoist .
- Before driving over a workshop hoist , en sure that there i s
sufficient clearance between the hoist and low parts of the
vehicle. •
