CATALYTIC CONVERTER
The exhaust system on most petrol engine
vehicles and some diesel vehicles
incorporates a catalytic converter, which
converts poisonous exhaust emissions from
the engine into environmentally less harmful
gases.
WARNING
The catalytic converter can be easily
damaged through improper use, particularly
if the wrong fuel is used, or if an engine
misfire occurs. For this reason it is VERY
IMPORTANT that you heed the precautions
which follow:Filling up with fuel

Catalytic converter
75 Driving
·
Provided the engine has reached its
normal operating temperature, if a misfire
is suspected or the vehicle lacks power
while driving, it may be driven SLOWLY
(at risk of damaging the catalyst) to a
Land Rover dealer for assistance.
·
NEVER allow the vehicle to run out of fuel
(the resultant misfire could destroy the
catalyst).
·
Engines burning excessive oil (blue smoke
from the exhaust) will progressively
reduce catalyst efficiency.
·
On rough terrain do not allow the...

Fuel filling
76 PETROL ENGINES:
All engines fitted with a catalytic converter:
Use ONLY - 95 RON UNLEADED fuel.
Engines without a catalytic converter:
Use 95 RON UNLEADED petrol wherever
possible.
In territories where only LEADED fuel is
available, the following specifications
apply:
V8i high compression engines (9.35:1) - use
97 RON fuel.
V8i low compression engines (8.13:1) - use
90 RON fuel.
NOTE:
Leaded fuel is NOT suitable for MPi
engines

WARNING
To avoid any sudden discharge of fuel while
removing the cap, rotate the cap one half
turn to allow the fuel tank to vent. DO NOT
fully remove the cap until any hissing has
stopped.

Fuel filling
Filling station pumps are equipped with
automatic cut-off sensing to avoid fuel
spillage - only fill the tank until the filler nozzle
automatically shuts off. DO NOT attempt to fill
the tank beyond this point or spillage could
result due to expansion of the fuel.
Petrol engine vehicles:
On petrol engine vehicles which are designed
to operate ONLY on unleaded fuel, the fuel
tank filler neck will ONLY accept a narrow filler
nozzle of the type found on pumps that deliver...

DO NOT RUN THE FUEL TANK DRY!
In the case of vehicles equipped with a
catalytic converter, running the fuel tank dry
could create an engine misfire capable of
damaging the catalytic converter.
In the case of diesel engine vehicles, qualified
assistance will be required to prime the fuel
system before the engine can be restarted.
SAFETY ON THE FORECOURT
Petroleum gases are highly inflammable
and in confined spaces are also explosive.
Always take sensible precautions when...

MANUAL TRANSMISSION
Manual transmission vehicles feature a five
speed main gearbox and a two-speed transfer
box. In addition, a central differential in the
transfer box distributes the drive to the front
and rear axles, providing permanent four
wheel drive. By using the main gearbox in
conjunction with the transfer gears, ten
forward and two reverse speeds are available.
The gear positions for the main gearbox are
shown on the gear lever knob. Note that when
the gearbox is in...

AUTOMATIC TRANSMISSION
The Automatic transmission features a four
speed main gearbox with a torque converter
and a two speed transfer box. A central
differential in the transfer box distributes
power to both front and rear axles, providing
permanent four wheel drive. Using the main
gearbox in conjunction with the transfer
gearing produces eight forward and two
reverse speeds.

Automatic gear changing is limited to first,
second and third gears only. Use in
congested traffic conditions and for town
driving.
2 1st and 2nd gears
Automatic gear changing is limited to first
and second ratios only. Use when driving
up steep gradients and for negotiating
very narrow twisting roads. This position
also provides moderate engine braking for
descending slopes.

Use on very severe gradients, particularly
when towing, and...

83 Gear change speeds
With D selected, the road speed at which
gear changes take place will vary according to
the position of the accelerator: minimum
acceleration will result in low road speed gear
changes, while larger throttle openings will
cause the gearbox to delay gear changes until
faster road speeds have been reached
(thereby increasing acceleration).
With practice, gear changes can be made to
occur at a wide range of road speeds
depending on accelerator pedal pressure.
