TIGHTENING SEQUENCE
NOTE
Periodically check the spare tire inflation pressure.
Tire pressure should be the maximum pressure
specified in the chart.
NOTE
Periodically check that the spare is securely
fastened in its compartment.
CAUTION
Before driving, be sure the flat tire, track, jack and
tools are securely reinstalled in their respective
compartments.
CAUTION
Check that the bumper is securely closed shut
before driving.
SUPER SINGLE TIRE REPLACEMENT
Increase tire pressure to 125 PSI (862 kPa) if you are
using the supplied 365/70 R 22.5 spare tire to replace
a super single tire on the drive axle.
In this particular configuration, spare wheel is to be
used for emergencies only and for temporary use.
WARNING
l Spare tire pressure should be increased to
125 PSI.
l Do not exceed 80km/h (50 MPH)
l Repair and re-install original super-single
wheel and tire as soon as possible.
l While the spare tire is installed, avoid sharp
turns, sudden acceleration and braking.
WARNING
Before driving, be sure the flat tire, track, jack and
tools are securely reinstalled in their respective
compartments. Check that the bumper is securely
closed shut before driving.
EMERGENCY AIR-FILL VALVES
The vehicle is equipped with two air system
emergency fill valves to supplement the air system
when air pressure is low and the engine cannot be
operated. One valve is located inside the front
service compartment. The other valve is located
inside the engine compartment.
Both air system emergency fill valves are fitted with
standard tire valve stems. The air systems can be
filled using any standard external air supply line. The
fill valve located in the engine compartment supplies
air for all systems (brakes, suspension and
accessories). The fill valve located in the front
service compartment supplies air for accessories
only.
CAUTION
Air filled through the two emergency fill valves will
pass through the standard air filtering- drying
system. Do not fill air at any other location. Do not
exceed 120 psi (827 kPa).
