Outside temperature
display
The outside temperature is displayed in the sta-
tus bar @) 9 page 11.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
14
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the motor.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A\.

ZA WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.

Engine oil temperature
indicator

play --- °F (--- °C) appears in the instrument clus-
ter. The engine has reached its operating temper-
ature when the engine oil temperature is be-
tween 176 °F (80 °C) and 248 °F (120 °C) under
normal driving conditions. The engine oil temper-
ature may be higher if there is heavy engine load
and high temperatures outside. This is not a
cause for concern as long as the Ei => page 217

Fig. 32 Vehicle rear: foot motion (example)
The luggage compartment lid can be opened and
closed automatically 1) > A\ in General informa-
tion on page 36.
Requirements: you must be carrying your conven-
ience key* with you. The ignition must be switch-
ed off. You must be standing at the center behind
the luggage compartment lid.
> Move your foot back and forth under the bump-
er one time > fig. 32. Do not touch the bumper.
Make sure you have firm footing. The luggage
compartment lid will open or close )) once the
system detects the movement. The automatic
opening or closing will be canceled if you re-
peat one of the movements described.

ZX WARNING
Follow the safety precautions > page 36.
@ Tips
The luggage compartment lid will only open
or close )) if you perform the movement as
described. This prevents the luggage com-
partment lid from opening or closing due to
similar movements ), such as when you walk
between the rear of the vehicle and your ga-
rage door. In some situations, the function
may be limited or temporarily unavailable.
This may happen if:


D_ The closing function applies to vehicles that also have au-
tomatic luggage compartment lid operation.
— You are standing too close to the bumper or
too far away from it
— The luggage compartment lid was closed or
opened immediately beforehand
— You park close to a hedge and the branches
move back and forth under the vehicle for a
long period of time
— You clean your vehicle, for example with a
pressure washer or in a car wash
— There is heavy rain
— The bumper is very dirty, for example after
driving on salt-covered roads
— There is interference to the vehicle key's ra-
dio signal, such as from mobile devices or
remote controls

Sitting correctly and safely

Correct safety belt positioning

B4H-0751


RAZ-0696


Fastened safety belts only offer optimal protec-
tion during an accident and reduce the risk of se-
rious injury or death when they are positioned
correctly. Furthermore, the correct safety belt
position holds the vehicle occupant in place so
that a deployed airbag can provide maximum
protection. Therefore, always fasten the safety
belt and make sure it is positioned correctly
> fig. 63.
To ensure the safety belt is positioned correctly,
make sure of the following points:
—The lap portion of the safety belt must be locat-
ed across the lap.
—The shoulder portion of the safety belt must
rest over the center of the shoulder.
— The safety belt must always rest flat and se-
curely on the body.
For pregnant women, the safety belt must rest
evenly across the chest and as low and flat as
possible on the lap, so that no pressure is applied
to the lower abdomen. This should be done
throughout the entire pregnancy > fig. 64.


ZA WARNING
Incorrect safety belt positioning can cause se-
rious injury in the event of an accident or dur-
ing sudden braking or driving maneuvers.
— Never drive with the backrest reclined ex-
tremely far. The more the backrest is tilted
back, the greater the risk of injury due to the
safety belt being routed incorrectly.
— The safety belt itself or a loose safety belt
can cause serious injuries if it shifts onto
soft areas of the body, such as the stomach.
— The shoulder portion of the safety belt must
lie over the center of the shoulder and
chest, and never under the arm, behind the
back, or across the neck or face.
— The lap portion of the safety belt must lie
across the lap and never over the stomach.
—The safety belt must lie flat and securely on
the upper part of the body and the lap.
— The belt webbing must not be pinched or
twisted, or rub against sharp edges.
— If the safety belt height is set incorrectly
and/or the safety belt is routed incorrectly,
then the safety belt's protective function
will be impaired in the event of an accident.
Make sure the safety belt is at the right
height and is routed correctly for the pas-
senger using it.
— A safety belt that is too loose may lead to in-
juries during an accident, because your body
will move farther forward due to kinetic en-
ergy and will be stopped abruptly by the
belt.
— Heavily bulky, loose clothing (for example, a
coat over a sports jacket) may prevent the
seat and safety belts from functioning cor-
rectly.
— Do not position the safety belt over hard or
breakable objects (such as glasses, pens,
etc.).
— The lap belt portion of the safety belt must
sit as low as possible on the lap of pregnant

women and lie flat under the belly.

@) Note
Make sure that there are no hook-and-loop
fasteners or sharp objects such as zippers or

Stowing and using


— Applies to: vehicles with luggage compart-
ment cover: The luggage compartment cov-
er must always be securely fastened when in
use to reduce the risk of an accident.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Always stow objects securely in
the luggage compartment and secure them
at the tie-downs. Use straps suitable for
heavy objects.
— If pieces of luggage or objects are secured
to the tie-downs with unsuitable or dam-
aged straps, this can increase the risk of in-
jury during braking maneuvers or accidents.
— When transporting heavy objects, the vehi-
cle characteristics will change due to the
shift in the center of gravity, which increases
the risk of an accident. You may need to
adapt your driving style and speed to the
current conditions.
— The cargo net is only strong enough to se-
cure light objects. Heavy objects are not ade-
quately secured. Attempting to secure heavy
objects increases the risk of injury.
— Never exceed the permitted axle and load
and vehicle weight > page 278.
— Never secure a child safety seat to the tie-
downs.
— Never leave your vehicle unattended, espe-
cially if the luggage compartment lid is
open. Children could enter the luggage com-
partment and close the luggage compart-
ment lid from the inside. This creates the
risk of fatal injury, since the children would
be locked in and may not be able to escape
by themselves.
— Do not allow children to play in or on the ve-
hicle. Close and lock the luggage compart-
ment lid as well as all other doors when you
leave
the vehicle.
— Never transport passengers in the luggage
compartment. Every passenger must be cor-
rectly secured with the safety belts in the
vehicle > page 64.
— Be careful when releasing the backrest and
folding
it forward. To reduce the risk of be-


ing pinched, pay attention and check when
folding backrests forward.
— The backrest must be securely latched so
objects cannot slide forward out of the lug-
gage compartment during sudden braking.
— The backrest must be latched securely to en-
sure that the safety belt is protecting the
center seating position.
— Always pull forward on the backrest to make
sure it is check if it is correctly locked in
place.

() Note
—To reduce the risk of damage, move the rear
head restraints down before folding the rear
backrests forward > page 63.
— When folding the backrest forward, make
sure the outer safety belts are in the belt
guide recess so that they do not get pinched
in the backrest lock and damaged. Other ob-
jects should be removed from the rear
bench seat to protect the backrest from
damage.
— To reduce the risk of damaging the front
seats, make sure there is enough space be-
tween the front seat and the rear seat
equipment when folding the center backrest
forward.
— If you move the front seat back when the
rear seat backrest is folded forward, you
could damage the head restraints on the
rear seat.
— Make sure that the heating grid strips for
the rear window defogger are not damaged
by abrasive objects.
— Applies to: vehicles with manual luggage
compartment cover: Let the luggage com-
partment cover roll up slowly to reduce the
risk of damage.
— Applies to: vehicles with partition net: Let
the partition net roll up slowly to reduce the
risk of damage.
(i) Tips
— The tire pressure must be adapted to the
load > page 237.
— You can purchase straps at specialty stores.

Warm and cold

The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (+22°C) or higher. The temperature
is controlled automatically.
You can switch the defroster on or off using the
& button. You can switch the function off by
pressing a knob (4).
@ Rear window defogger
The rear window defogger only operates when
the engine is running. It switches off automati-
cally after 10 to 20 minutes, depending on the
outside temperature.
To prevent the rear window defogger from
switching off automatically, press and hold @ for
more than three seconds. This is stored until the
ignition is switched off.
Vents
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con-
sole using the ridged thumbwheels. The levers
adjust the direction of the airflow from the vents.
Residual heat
You can activate the residual heat function when
the ignition is switched off by pressing the knob
@ (left side). The residual heat from the coolant
is used to heat the vehicle interior. The residual
heat function switches off automatically after
about 15 minutes.

ZA WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating* function. To reduce
the risk of injury, these individuals should
not use seat heating”.
