2014 AUDI Q7 wheel alignment

.,.Check the tire sidewall
(i=> page 284, fig. 253) to de­
termine the designated load rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Fig. 252 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig. 251 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators . Worn tires must be replaced.
Different figures may apply in other countries
c::> &. .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out . For this
Tires and wheels 283
reason , tire pressure must be checked at least
once a month
c::> page 2 79.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing:
- Tire rotation intervals may differ from the
vehicle service intervals outlined in your
Warranty & Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pared to all-wheel drive (q uattro).
- Please rotate tires as shown
c::> fig. 252.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 301.
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal­ anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle.
If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.

300 What do I do now?
& WARNING
-You or your passengers could be injured
while changing a wheel if you do not
follow these safety precautions:
- Position the jack only at the designated
lifting points and align the jack. Other­
wise, the jack could slip and cause an injury if it does not have sufficient hold
on the vehicle.
- A soft or unstable surface under the
jack may cause the vehicle to slip off the jack. Always provide a firm base for
the jack on the ground . If necessary,
use a sturdy board under the jack.
- On hard, slippery surface (such as tiles)
use a rubber mat or similar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passengers:
- Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the vehicle and
well away from the road and traffic.
- Make sure jack position is correct, ad­
just as necessary and then continue to
raise the jack.
(D Note
Do not lift the vehicle by the sill. Position
the jack only at the designated lifting
points on the sill. Otherwise , your vehicle
will be damaged.
