136Driving and operating
operations 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■ Transfer box and underguard
■ Engine oil pan and underguard
Observe the following: ■ Do not spray high-pressure water directly at the vehicle seals
■ The wheels must be removed to clean all mud and stones from the
brake calipers and to check brake
pad wear
■ The areas on the upper side of the underguards must be cleared of
stones, to prevent damage to the
engine oil pan and the fuel tank
Driving and operating141
FaultThe yellow control indicator u flashes
to indicate that the system is not ready for conditions to operate, due to the high temperature (approx.
350 - 400 °C) of friction material,
through severe or repeated braking. It
will extinguish when the temperature
drops below 350 °C.
The yellow control indicator u
illuminates when there is a
malfunction in the system, due to the
extremely high temperature
(over 400 °C) of friction material,
through severe or repeated braking. It will extinguish when the temperaturedrops below 350 °C. These
temperatures may differ according to
vehicle conditions or outside
conditions.
Flashing or illumination of the yellow
control indicator u reminds the driver
that the friction material needs to cool
down: drive the vehicle without
braking as much as possible. If the
control indicator does not extinguish,
have the cause of the fault remedied
by a workshop.DSC control indicators u 3 87.
Automatic level control The rear level of the vehicle is
automatically adjusted to the load
conditions while driving. Suspension
and ground clearance are increased,
which improves driving conditions.
The automatic level control is
activated after the vehicle has been
driven for some distance, depending
on the vehicle load and the road
conditions.
Do not use full payload in the event of
a fault. Have the cause of the fault
remedied by a workshop.
Headlight range adjustment 3 107.Driver assistance
systems9 Warning
Driver assistance systems are
developed to support the driver
and not to replace the driver's
attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 25 mph.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
For safety reasons the cruise control
cannot be activated until the foot
brake has been operated once.
192Vehicle care
4. Switch on electrical consumers(e.g. headlights, heated rear
window) of the vehicle receiving
the jump start.
5. Operate discharged vehicle for approx. 20 minutes to allow for
adequate battery recharging.
6. Reverse above sequence exactly when removing leads.Towing
Towing the vehicle
Remove the spoiler lip from the front
left-hand side of the vehicle by
unfastening the six screws located on the underside of the vehicle. Then
attach the towing eye.
The towing eye is stowed with the
vehicle tools 3 175.
Screw in the towing eye as far as it will
go until it stops in a horizontal
position.
Attach a tow rope - or better still a tow
rod - to the front towing eye, never to
the bumper or front suspension units.
Do not tow the vehicle from the rear.
The front towing eye must only be
used for towing and not recovering a
vehicle.
Switch on ignition to release steering wheel lock and to permit operation of
brake lights, horn and windscreen
wiper.
Transmission in neutral.
