relay AUDI Q5 2014 Owners Manual

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trailer, please remember
that the additional load will affect durability,
economy and performance .
T railer towing not only places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
For this reason, always follow the operating
and driving instructions provided and use
common sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
ble for your vehicle and trailer and must be
mounted securely on the vehicle's chassis at a
technically sound location. Use only a trailer
hitch with a removable ball mount. Always
check with the trailer hitch manufacturer to
make sure that you are using the correct
hitch.
Do not use a bumper hitch.
T he hitch must be installed in such a way that
it does not interfere with the impact-absorb­
ing bumper system. No modifications should
be made to the vehicle exhaust and brake sys­
tems . From time to time, check that all hitch
mounting bolts remain securely fastened.
When you are not towing a trailer, remove the
trailer hitch ball mount. This prevents the
hitch from causing damage should your vehi­
cle be struck from behind
¢ &. .
Trailer brakes
If your trailer is equipped with a braking sys­
tem, check to be sure that it conforms to all
regulations .
Trailer towing 213
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system
¢ &. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
Trailer lights must meet all regulations . Be
sure to check with your authorized Audi dealer
for correct wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you
using the regular outside mirrors, then you
must install extended mirrors.
It is important
that you always have clear vision to the rear .
.8, WARNING
- If a trailer has electrical brakes please
note that these brakes are not activated
by the factory-fitted control unit -risk of
accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and
injure you or your passengers.
- Never install a "weight distributing" or
"load equalizing" trailer hitch on your ve­
hicle. The vehicle was not designed for
these kinds of trailer hitches . The hitch
attachment can fail, causing the trailer
to tear loose from the vehicle .
- The Gross Vehicle Weight Rating for your
vehicle, found on the safety compliance
label on the driver's side B-pillar, must
never be exceeded under any circumstan­
ces. Exceeding the Gross Vehicle Weight
Rating of your vehicle is likely to damage
your vehicle, and such damage will not
be covered by your Limited New Vehicle
Warranty. Exceeding the Gross Vehicle
Weight Rating will also change the per­
formance and handling characteristics of
your vehicle, which could cause a crash resulting in serious injury or death.

-Always follow the operating instructions
provided by the battery charger manu­
facturer when charging your battery.
- Never charge a frozen battery.
It may ex­
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro­
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke . Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip­
ment.
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will seriously dam­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
¢ page 203. The intelligent energy manage­
ment system will keep the engine battery
charged better then vehicles without this sys­
tem . To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you
Checking and filling 245
install batteries of the same type and manu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­ cations are listed on the battery housing . Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­
rectly after replacing the battery .
If it is not possible to use a battery of this
type , the new battery must have the same ca ­
pacity, voltage (12 volts), amperage, con­
struction and plug sealing .
When installing the battery, make sure the ig­ nition and all electrical consumers are turned
off .
(D Note
-Make sure the ventilation hose on the
side of the battery is connected, other­
wise fumes or battery acid can leak out .
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop­
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi­
ronment. •

pair of jumper cables to start the en­
g ine.
Jumper cables
Use only jumper cables of sufficiently la rge
c ross section to carry the starter c urrent safe­
l y. Refer to the man ufacturer's specifications.
