The interior rear view mirror and the exterior rear view mirror on the driver’s side do not react, for example, when transporting cargo which covers the rear window.

Light hitting the mirror(s) at certain angles (incident light) could blind you. As a result, you may not be able to observe traffic con- ditions and could cause an accident.

Warning!

In case of an accident, liquid electrolyte may escape from the mirror housing if the mirror glass breaks.

Electrolyte has an irritating effect. Do not allow the liquid to come into contact with eyes, skin, clothing, or respiratory system. In case it does, immediately flush affected area with water, and seek medical help if necessary.

! Electrolyte liquid coming into contact with the vehicle paint finish can be completely removed only while in the liquid state and by applying plenty of water.

Warning!

Exercise care when using the passen- ger-side exterior rear view mirror. The mirror surface is convex (outwardly curved surface for a wider field of view). Objects in mirror are closer than they appear. Check your interior rear view mirror or glance over your shoulder before changing lanes.

The climate control is operational whenev- er the engine is running. You can operate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature and the current outside temperature.

Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system. The air conditioning will not engage (no cooling) if the A/C mode is deactivated (컄 page 216).

Warning!

Warning!

Follow the recommended settings for heat- ing and cooling given on the following pag- es. Otherwise the windows could fog up, impairing visibility and endangering you and others.

When operating the climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite to unpro- tected skin in the immediate area of the air vents.

Always keep sufficient distance between un- protected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 208) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Controls in detail Climate control

i Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled interval. A clogged filter will reduce the air volume to the interior. If the vehicle interior is hot, ventilate the interior before driving off, see “Summer opening fea- ture” (컄 page 239). The climate control will then adjust the interior temperature to the set value much faster. Keep the air intake grille in front of the wind- shield free of snow and debris.

The automatic climate control is a 3-zone intelligent automatic climate control sys- tem. Your vehicle interior is divided into 3 zones.

Warning!

When operating the automatic climate con- trol, the air that enters the passenger com- partment through the air vents can be very hot or very cold (depending on the set tem- perature). This may cause burns or frostbite to unprotected skin in the immediate area of the air vents.

Always keep sufficient distance between un- protected parts of the body and the air vents. If necessary, use the air distribution controls (컄 page 222) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin.

Controls in detail 3-zone automatic climate control*

With the help of a sun sensor, the automat- ic climate control determines the relation of the sun to the vehicle and automatically adjusts the inside temperature for every individual zone. The automatic climate control is operation- al whenever the engine is running. It cools the vehicle’s interior according to the an- gle and intensity of the sun’s rays, the out- side temperature and the selected temperature. You can operate the auto- matic climate control in either the auto- matic or manual mode. Nearly all dust particles, pollutants and odors are filtered out before outside air en- ters the passenger compartment through the air distribution system.
