coolant warning lamp
may also glow and a
warning tone may
sound.
The coolant level is too low. The coolant is too hot and the engine
is no longer being cooled sufficiently.
X
Stop as soon as possible and allow the engine and the coolant
to cool down.
X
Check the coolant level (

page 316). Observe the warning
notes as you do so and top up the coolant if necessary.
If the coolant level is correct, the engine radiator fan may be faulty.
The coolant is too hot and the engine is no longer being cooled
sufficiently.

Manual transmission
Gear lever
Gear lever
!
Only engage gear when the clutch pedal
is depressed.
!
When shifting between 5th and 6th gear,
you should always push the gear lever all
the way to the right. Otherwise, you could
shift unintentionally into 3rd or 4th gear
and damage the transmission.
If you shift down at too high a speed (trans-
mission braking), this can cause the engine
to overrev, leading to engine damage.
Do not use the clutch bite point to keep the
vehicle stationary on uphill gradients.
There is otherwise a risk of damaging the
clutch.
!
On long and steep downhill gradients,
especially if the vehicle is laden or towing
a trailer, you must shift into gear 1, 2 or 3
in good time. This uses the engine's braking
effect. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Shifting to neutral (N)
X
Depress the clutch pedal fully.
X
Move the gear lever to position N : .
