jump start terminals AUDI TT ROADSTER 2014 Owners Manual

Emergency situations
General
This chapter is intended for trained emer­
gency crews and working personnel who
have the necessary tools and equipment to
perform these operations.
Starting by pushing or
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.
_& 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 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 .
The ca pa city (Ah) of the booster battery
should not be lower than that of the dis­
charged battery.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c::;,page 165, Working in the
engine compartment.
(D Note
- App lying a higher voltage booster bat­
tery will cause expensive damage to sen­
sit ive electronic components, such as
control units, relays, rad io, etc .
- There must be no electrical contact be­
tween the vehicles as otherwise current
could already start to flow as soon as the
posit ive(+) terminals are connected. ..,. •

218 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem.
Use of jumper cables
Make sure to connect the jumper coble
clomps in exactly the order described below!
Fig. 165 Engine compart ment: Co nnectors for jumper
cables and charger
Fig. 166 Jump starting with the battery of another ve­
hicle: @discharged veh icle batte ry,® booste r battery
The procedure described below for connecting
jumper cables is intended to provide a jump
start for your veh icle.
Preparatory measures
1. Do not jump start a frozen battery! Re­
place such a battery!
2 . Otherwise apply the hand brake and put
the selector lever into P position.
3. For both vehicles switch off all consumers
and the ign ition.
Connecting/disconnecting the jumper
cable .
4. Connect one end of the red jumper cable
on the
jump start bolt@q fig. 166
(Bolts under red cover = "positive") of the
vehicle to be started @.
5. Connect the other end of the red jumper
cable to the positive terminal @of the
booster battery @.
6. Connect one end of the black jumper ca­
ble to the negat ive terminal @of the
booster battery @.
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
