2009 AUDI Q7 service schedule

If an individual wheel begins to rotate too slowly in relation to
vehicle speed and tends to lock, the ABS automatically reduces
brake pressure to prevent that wheel from locking.
This automatic adjustment process will cause a
slight vibration of
the brake pedal and some noises to alert you that vehicle speed
must be adapted to existing road and traffic conditions .
_& WARNING
Although the ABS is very effective, always remember that braking
capability is limited by tire traction. Always adjust your driving
speed according to the road and traffic conditions. Do not let the
extra safety afforded by the ABS tempt you into taking extra risks.
The ABS cannot overcome the laws of physics.
[ i] Tips
• If ABS is not functioning properly , a warning light will come on .
See
=> page 22.
• If a fault occurs in the ABS, the EDL is also not functioning. This
is indicated by the ABS warning light.•
Brake assistant
The brake assistant is designed to achieve the optimum
braking effect.
The brake assistant helps to increase the effective braking power
and thus to achieve
a shorter stopping distance . If the driver
presses the brake pedal very quickly , the brake assistant automati­
cally boosts the braking force to the maximum level, up to the point
where the anti-lock brake function (ABS) intervenes to stop the
wheels from locking. You should then keep th e brake pedal pressed
until the vehicle has braked to the required speed. The brake assis­
tant swi tches its elf off as soon as you release the brake pedal.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
Automatic full braking assist
This function allows full braking
in spite of high brake pedal forces
(e.g . when the brakes are severely stressed because the vehicle is
fully loaded) . The driver notices this function through a reduction of
pedal force and increased pedal travel. When the brake pedal is
released, full braking assist switches off again automatically.
If there is an ABS failure, the brake assistant and automatic full
braking assist ar e not available .
The brake assistant will not be operative if there is a malfunction in
the ABS.
_& WARNING
Please remember that the accident risk always increases if you
drive too fast, especially in corners or on a slippery road, or if you
follow the vehicle ahead of you too closely . Increased risk of an
accident cannot be compensated for even by the brake assistant,
so always maintain a safe speed. iJ
Servotronic® -advanced power
steering system
The power steering systems uses the power of the
running engine to allow precise steering with little effort.
The advanced Servotronic ® power steering system senses the road
speed and electronically adjusts power assistance to provide
comfortable and safe steering response exactly matched to the
vehicle speed.
Power steering will not work if the engine is off. As a result, the
s teering whe el will be hard to turn.
The power steering fluid level is checked during the scheduled
maintenance services .

Maintenance book let.
Und er di ffi cult ope rating cond ition s, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequen tly, etc., some service work shou ld be performed
between the intervals specified. This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
By regularly maintaining your vehicle, you help make sure that emis­

the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the general ly increasing technical
complexity of today's automobi les, have steadi ly reduced the scope
of maintenance and repa irs which can be carried out by vehicle
owners.
Al so, sa fety a nd e nvironment al concerns p lace very strict
limi ts on the na ture of repairs a nd adjustments to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
ability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dea ler or any other properly equipped and qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu­
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, origina l parts and trained spec ial ists
to keep your vehicle running proper ly.
