Refrigerator
Introduction
A ppl ies to: ve hicles w ith re fri ge rato r
-
Clean the refrigerator before the first use r=;, table
on page 308.
You can on ly switch the refrigerator on, if :
- the temperature in the luggage compa rtme nt
is less t han 131 ° F (5 5 °C). If the refr igerator is
switched on, it will automatica lly switch off if
the temperature in the luggage compartment exceeds 131 ° F (55 °(). If the temperature
goes back below 131 ° F (55 °(), the refr igera­
tor will automatically switch on again.
Seat s and sto rag e
-The charge level of the vehicle battery is suffi ­
cient. The refrigerator is automatica lly switch­
ed off if the e lectr ica l system vo ltage falls be­
low the spec ified min imum value. Th is prevents
the vehicle battery from discharging. The re­
frigerator automatically switches back on if the
electrical system voltage increases aga in, for
examp le after starting the vehicle .
When the cooling function is working opt imally,
the cooling funct ion reaches 43° F (+6 °() and
the freez ing funct ion reaches 21 ° F (-6 °() . The
cooling temperature in the refrigerator also de­
pends on the luggage compartment tempe ra­
tu re . When the temperatu re in t he luggage com ­
partment is hig h, there may on ly be a limited
cooling effect.
A WARNING
= -
To avoid any injury risks to the passengers
caused by the refrigerator, the following safe­
ty precautions must be followed:
- The maximum load capacity for the freezer
is 5.5 lbs (2.5 kg).
- Never overload the refrigerator. There
is a
risk of injury in the event of a co llision or
sudden braking.
- The refrigerator cover must always be
closed and locked whi le driving. The refr ig­
erator contents could enter the vehicle inte­
rior dur ing a coll is ion or sudden brak ing ma­
neuver, wh ich increases the r isk of injury.
- Never store flammable fluids, gas contain­
ers and similar objects in the refrigerator
due to the r isk of an explos ion . This also ap­
plies to goods and products that can emit
volat ile or flammab le gases.
- At temperatu res of 32° F (0 °C) and lower
frozen liquid inside glass containe rs ca n
cause t he containe rs to b urst.

The engine drives the generator, wh ich generates
electricity; the fue l consumption also increases
with the demand for electricity. Therefore, switch

need it. Examples of equipment that use a lot of
energy are air blowers at a high setting, the rear
window defogger and seat heating*.
CD Note
Do not leave engine idling unattended after
starting. If warning lights should come on to
ind icate improper operation, they would go
unheeded. Extended idling also produces
heat, wh ich could result in overheat ing or
other damage to the vehicle or other p roper-
ty.
CD Note
-Have your vehicle maintained properly and
i n accordance with the service recommenda­
tions in your Warranty
& Ma intenance book­
l et. Lack of proper maintenance as well as
i mproper use of the vehicle will impair the
function of the emission control system and

-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
.,. Bring the vehicle to a full stop.
.,. Select the P or N selector lever position .
.. Press the I START ENGI NE STOPI button
~ page 76, fig. 90.
Steering lock
The steering locks when you turn the engine off
using the lSTART
ENGINE STOPlbutton and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function
If it is absolutely necessary, the engine can also
be turned off while driving in the
R, Dor S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
-Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
cou ld be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
-For safety reasons, always park the vehicle
with the selector lever in the P position .
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons :
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.
