Rocking the Vehicle
▼Rocking the Vehicle
WARNING
Do not spin the wheels at high speed,
and do not allow anyone to stand
behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tyre could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating , transmission failure, and
tyre damage.
If you must rock the vehicle to free it
from snow, sand or mud, depress the
accelerator slightly and slowly move
the shift lever/selector lever from 1 (D)
to R position.
Winter Driving
▼Winter Driving

chains, window scraper,
flares, a small
shovel, jumper leads, and a small bag
of sand or salt.

an Authorised Mazda Repairer) to
check the following:
xHave the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page
6-28.
xInspect the battery and its leads.
Cold reduces battery capacity.
xUse an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
6-24).
xInspect the ignition system for
damage and loose connections.
xUse washer fluid made with
antifreezeŠbut do not use engine
coolant antifreeze for washer fluid
(page 6-31).

left on the windscreen is dangerous
as it could obstruct vision.
xDo not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
