towing
(D Note
Vehicles with an automatic transmission
cannot be started by pushing or towing .
Starting with jumper
cables
If necessary, the engine can be started by
connecting it to the battery of another vehi­
cle.
If the engine should fail to start because of a
discharged or weak battery, the battery can be
connected to the battery of
another vehicle,
using a
pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently
largecross section to safely carry the starter
current. Refer to the manufacturer's specifica­
tions.
Use only jumper cables which have
insulated
termina l clamps and are properly marked for
distinction :
plus(+) cable in most cases colored red
minus(-) cable
in most cases colored black.

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 you r eyes and avoid lean­
ing over the battery whenever possible.
Emergency situations 21 7
-A discharged battery can already freeze
at temperatures just below 32 °F (0 °C).
Before connect ing a jumper cable, the
frozen battery must be thawed com­
pletely, 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 batter ies generate explosive gas­
es. Keep sparks, flame and lighted c iga­
rettes away from batteries.
- Do not try to jump start any veh icle w ith
a low ac id 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 bat­
tery. Use of batteries of diff erent voltage
or substantially different "Ah" rat ing
may cause an exp losion and personal in­
jury.
- Never charge a frozen battery. Gas trap­
ped 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) rat ­
ing may cause an exp losion and injury .

7. Connect the other end of the black jumper
cable to the negative terminal (bolt head)
@ in the external start ing point @ of
your vehicle.
8. Route the jumper cables so that they can­
not catch in any rotating parts in the en­
gine compartment.
Starting the engine
9. Start the engine of the vehicle providing
assistance and allow it to run at id le .
10. Now start the engine of the vehicle with
the discharged battery, wait for two to
three minutes until the engine "runs"
smoothly.
11. If the eng ine does not start: Stop try ing
after 10 seconds and then try again after
about 30 seconds.
12. In the vehicle that has received start as­
sistance, turn on the heater blower and
the rear window heating to elim inate any
vo ltage peaks when disconnecting . Driv­
ing lights must be switched off!
13 . Disconnect the cable while the engine is
running exactly in
reverse order to that
described in¢
page 218, Connecting/dis­
connecting the jumper coble ..
When do­
ing so, make sure that the cable cannot
contact rotating eng ine parts.
14. Close the cover on the positive terminal.
The battery is vented to the outside to prevent
gases from entering the vehicle inter ior. Make
sure that the jumper clamps are well connect­
ed with their
metal parts in full contact with
the battery terminals.
A WARNING ~
To avoid serious personal injury and dam-
age to the vehicle, heed all warnings and

instructions of the jumper cable
manufacturer. If in doubt, call for road
service.
- Jumper cables must be long enough so
that the vehicles do not touch.
- When connecting jumper cables, make
sure that they cannot get ca ught in any
moving parts in the eng ine compart­
ment.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
