Vauxhall Combo Owner's Manual

z The fuel supply is automatically shut off 

during overrun, e.g. when the vehicle is 

being driven down long gradients or 

when braking – see page 118. 

z To enable the overrun cut-off to come 

into action and save fuel, do not 

accelerate or depress clutch pedal 

during overrun. 

z High revs increase engine wear and fuel 

consumption. 

z Do not race your engine. Avoid driving at 

high engine speeds. 
Making use of the tachometer helps to 

save fuel. Drive in a low engine speed 

range for each gear as much as possible 

with uniform engine speeds. Drive as 

often as possible in top gear, select the 

next higher gear as soon as possible, 

and only change down when the engine 

is no longer running perfectly smoothly. 

z The higher the speed, the higher the 

consumption and the noise level. At top 

speed, you consume a great deal of fuel 

and produce excessive noise and 

exhaust emissions. 

z Slightly releasing the accelerator pedal 

results in distinct fuel savings with no 

major loss of speed. 
Drive at no more than around three 

quarters of maximum speed and you will 

use up to 50% less fuel, without losing a 

great deal of time. 

z Inadequate tyre pressure, leading to 

higher road resistance, costs money in 

two ways: for more fuel and increased 

tyre wear. 

z Regular checks (every 14 days) pay off. 

z The power consumption of electrical 

equipment increases fuel consumption. 

z Switch off all auxiliary electrical loads 

(e.g. air conditioning 3, heated rear 

window 3) when not needed. 

z Due to air resistance, a roof load 

can increase fuel consumption by 

approx. 3.5 gal./1000 miles (1 l/100 km). 

z Remove them if they are not being used. 

z Improper repairs or adjustment and 

maintenance work can increase fuel 

consumption. Do not carry out work on 

the engine yourself. 
You may out of ignorance infringe 

environmental laws by not disposing of 

materials properly. 
Appropriate parts might not be recycled. 
Contact with some of the materials 

involved may pose a health hazard. 

z We recommend that repair and 

maintenance be entrusted to your 

Vauxhall Authorised Repairer.

z Going up steep slopes, cornering, driving 

on poor roads and winter driving all 

increase fuel consumption. 
Fuel consumption increases dramatically 

in urban traffic and at winter 

temperatures, especially on short trips 

when the engine operating temperature 

is not reached. 

z Follow the hints given above to keep 

consumption to a minimum under such 

conditions.
