Warning (Continued)
manufacturer recommends it for
the vehicle's tyre size combination
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 235/
65R18 size tyres, 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
0 263. 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
underinflated or flat may cause a
blowout and a serious crash. Never
attempt to re-inflate a tyre that has
been driven on while severely
underinflated or flat. Have your
dealer or an authorised tyre service
centre repair or replace the flat tyre
as soon as possible.
