and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive slow
and readjust or remove the traction
device if it contacts the vehicle. Do
not spin the wheels. If traction
devices are used, install them on
the front tyres.
Caution
If the vehicle is equipped with a
tyre size other than 245/45R20, use
tyre chains only where legal and
only when necessary. Use low
profile chains that add no more
than 12 mm thickness to the tyre
tread and inner sidewall. Use chains
that are the proper size for the
tyres. Install them on the tyres of
the front axle. Do not use chains on
the tyres of the rear axle. Tighten
them as tightly as possible with the
ends securely fastened. Drive slowly
and follow the chain manufacturer's
instructions. If the chains contact

the vehicle, stop and retighten
them. If the contact continues, slow
down until it stops. Driving too fast
or spinning the wheels with chains
on will damage the vehicle.
If a Tyre Goes Flat
It is unusual for a tyre to blow out
while driving, especially if the tyres
are maintained properly. See Tyres
0 319. If air goes out of a tyre, it is
much more likely to leak out slowly.
But if there is ever a blowout, here are
a few tips about what to expect and
what to do:
If a front tyre fails, the flat tyre
creates a drag that pulls the vehicle
toward that side. Take your foot off
the accelerator pedal and grip the
steering wheel firmly. Steer to
maintain lane position, and then
gently brake to a stop, well off the
road, if possible.
A rear blowout, particularly on a
curve, acts much like a skid and may
require the same correction as used in
a skid. Stop pressing the accelerator
pedal and steer to straighten the
vehicle. It may be very bumpy and
noisy. Gently brake to a stop, well off
the road, if possible.

Warning
Driving on a flat tyre will cause
permanent damage to the tyre.
Re-inflating a tyre after it has been
driven on while severely
underinf lated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tyre that has
been driven on while severely
underinf lated or flat. Have your
dealer or an authorised tyre ser vice
centre repair or replace the flat tyre
as soon as possible.

Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the appropriate
safety equipment and training. If a
jack is provided with the vehicle, it
is designed only for changing a flat
