134Driving and operating
Towing the vehicle 3 188.
Driving through water
Do not exceed the maximum wading
depth 3 204.
Check the depth of water: choose the
lowest entry and departure angles
before entering. Maintain a steady
engine speed, to help prevent water
from entering the exhaust system, but do not exceed 3 mph, to avoid
splashing the water.
Drive with the flow wherever possible,
not against it. If you have to drive
against the flow, try to drive at an
angle to it, so that the leading corner
of the vehicle will help deflect water
from the engine compartment. Avoid
splashing the water - if the ignition
system becomes wet, the engine may
stall.
Avoid water entering the air intake
system. If water enters the air intake
system, engine seizure with severe
costly damage may result.
Test the brakes after leaving the
water - wet brakes are less effective
than dry ones. Perform the serviceoperations for wading , involving
checks for water contamination, at
the earliest opportunity.
Service checks after wading
Check for the ingress of water into the following:
■ Brake fluid reservoir
■ Air cleaner element
■ Engine
■ Transmission
■ Axles
■ Interior of vehicle
Renew any lubricating oil or hydraulic
fluid that has a milky appearance,
indicating contamination with water.
Cleaning
Clean the vehicle thoroughly and as
soon as possible after driving off-
road.
Do not let mud remain dry on any part
of the vehicle as it becomes abrasive
and can damage paint, glass, seals,
bearings and brake components. If
left to build up, mud can seriously
affect the airflow through and overmechanical components and cause
localised overheating and failure of
parts, especially in the engine
compartment.
Ensure the radiator core and the area between the radiator and intercooler/
oil cooler (where installed) is cleaned, to maintain proper cooling air flow.
Check the radiator and cooler cores
for blockage (sand, silt etc.).
Check the tyre treads.
Clean and check the mechanical
parts of the vehicle, particularly the following areas:
■ Driveshafts, including sealing bellows
■ Front brake calipers, pads and discs
■ Front suspension
■ Clutch fork sealing bellows
■ Rear brake calipers, pads and discs
■ Rear suspension
■ Fuel tank and underguard
■ Breathers, axles and fuel tank
■ Load sensing valve
