Avoid full throttle and high speeds
Fuel consumption will be halved if only three-quarters of the possible top
speed of your vehicle is used.
Reducing idling
When the engine is switched off, such as when waiting in a traffic jam, the fuel
economy is already greater after 30 - 40 s than the fuel quantity which is re-
quired for engine re-start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 185.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 1 l/100 km. At a speed of
100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Electrical consumers (e.g. seat heating, air conditioning and the like) only turn
on for as long as necessary.
Driving through water and driving off of made-up roads
Introduction
This chapter contains information on the following subjects:
Driving through water
137
Driving off paved roads 138
WARNING
Immediately after driving through water, mud, slush and the like, braking
effectiveness will be temporarily impaired » page 131, Information on brak-
ing . For this reason, sudden and violent braking manoeuvres are to be
avoided - there is a risk of accident!
Driving through water
Fig. 126
Driving through water
Read and observe on page 137 first.
The following must be observed to avoid damage to the vehicle when driving
through bodies of water (e.g. flooded roads).
›
Therefore determine the depth of the water before driving through bodies of
water.
The water level must not reach above the web of the lower beam » Fig. 126.
›
Do not drive any faster than at a walking speed.
At a higher speed, a water wave can form in front of the vehicle which can
cause water to penetrate into the air induction system of the engine or into
other parts of the vehicle.
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■
When driving through water, some parts of the vehicle such as the engine,
gearbox, chassis or electrics can be severely damaged.
■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Potholes, mud or rocks can be hidden under the water, making it difficult or
impossible to drive through the body of water.
■
Do not drive through salt water, as the salt can cause corrosion. An vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
