essary ( Y
page 408). The value on the wheel
or as given in the "Wheels and tires" section is
valid ( Y
page 441).
An emergency spare wheel may also be
mounted against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel.
Replace the tires after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
i When you are driving with the collapsible
spare wheel mounted, the tire pressure
loss warning system or the tire pressure
monitor cannot function reliably. Only
restart the tire pressure loss warning sys-
tem or tire pressure monitor when the
defective wheel has been replaced with a
new wheel.
Vehicles with tire pressure monitor:
after mounting an emergency spare wheel,
the system may still display the tire pres-
sure of the removed wheel for a few
minutes. The value displayed for the moun-
ted emergency spare wheel is not the same
as the current tire pressure of the emer-
gency spare wheel.
Removing the emergency spare wheel
Vehicles with a "Minispare" emergency
spare wheel under the cargo compart-
ment floor
Always observe the instructions and safety
notes in the "Mounting a wheel" section
( Y
page 428). Emergency spare wheel (example: vehicle without
lockable cargo compartment floor) X
To remove the emergency spare wheel:
lift the cargo compartment floor up

Technical data

Vehicles with the ON&OFFROAD package:
the maximum gradient climbing ability is
100% when the LOW RANGE off-road gear is
selected.
Vehicles without the ON&OFFROAD pack-
age: the maximum gradient climbing ability is
80%.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep ter-
rain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS recognizes this and brakes the
wheels accordingly. The rear wheel torque
is increased, making it easier to drive off.
For further information about the maximum
gradient climbing ability, see ( Y
page 202).

! If you have a trailer tow hitch retrofitted,
changes to the cooling system and drive
train may be necessary, depending on the
vehicle type.
If you have a trailer tow hitch retrofitted,
