186Vehicle careCaution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is held under the
vehicle frame using a winch and
secured by tightening a cable using
the wheel wrench and adapters
(depending on vehicle).
It may be necessary to jack the
vehicle up to gain access to the spare
wheel on a fully loaded vehicle with a flat rear tyre.
To release the spare wheel, loosen
cable by connecting the wheel
wrench and adapters (depending on
vehicle) to the slot position illustrated
and lower the wheel fully by turning
wrench clockwise.
Caution
Only use the wheel wrench and
adapters (depending on vehicle)
to lower the spare wheel.
The use of pneumatic tools is
prohibited. This may result in
damage to the winch cable and
equipment.
Place wheel upright, unclip retainer
from wheel rim and release the wheel
from the cable and connected
retainer by routing these components through the centre of the wheel.
Twin rear wheel vehicles have an
additional mounting plate attached to
the spare wheel. Before using the
wheel, undo the nut and remove the
mounting plate.
Page 189 of 233

Vehicle care187
When reinstalling a spare wheel, first
attach the mounting plate (twin rear
wheel vehicles) and secure with the
nut.
Place wheel upright, then route the
cable and connected retainer from
the front of the wheel (side with tyre
valve) and through the centre of the
wheel. Attach the retainer and clip it
into place, ensuring it is correctly
positioned and that the front of the
wheel (side with tyre valve) will be
facing upwards when reinstalled.
Place wheel below the vehicle frame,
directly beneath the winch
mechanism, then tighten cable using
the wheel wrench and adapters by
connecting to the slot position
illustrated above and turning wrench
anticlockwise until the wheel is
secured in the fully raised position.9 Warning
Ensure the front of the wheel (side
with tyre valve) is facing upwards
when the spare wheel is
reinstalled below the vehicle
frame.
Temporary spare wheel
Caution
The use of a spare wheel that is smaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 180.
Summer and winter tyres
If you use winter tyres, the spare
wheel may still be fitted with a
summer tyre.
If you use the spare wheel when it is
fitted with a summer tyre the vehicle's driveability may be affected,
especially on slippery road surfaces.
Directional tyres Fit directional tyres such that they rollin the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
