STARTING AND DRIVING
}}
401
Location of the backup reader in the tunnel console.
If the Vehicle key not found message is shown
in the instrument panel at start, place the remote key at the backup reader and then make a newstart attempt.
NOTE
When the remote key is placed in the backup reader, make sure that no other vehicle keys,metal objects or electronic devices (e.g. cellu-lar phones, tablets, laptops or chargers) are inthe backup reader. Multiple vehicle keys closeto each other in the backup reader can dis-rupt their functionality.
CAUTION
If the engine has not responded after 3 attempts – wait for 3 minutes before startinga new attempt. Starting capability increases ifthe starter battery is given time to recover.
WARNING
Never remove the remote control key from
the vehicle while driving or the vehicle is being towed.
WARNING
• Always remove the remote key from the passenger compartment when you leavethe vehicle and make sure the ignition is in mode
0.
• Always put the gear selector in
P and
apply the parking brake before leaving the vehicle. Never leave the vehicle unsu-pervised while the engine is running.
• Always open the garage door fully andmake sure that ventilation is very goodbefore starting the engine in a garage.The exhaust fumes produced by the vehi-cle contain carbon monoxide, which isinvisible and odorless but very toxic.
WARNING
Always take along the remote control key when leaving the vehicle and make sure thatthe vehicle electrical system is in ignition mode
0 – especially if there are children in
the vehicle.
NOTE
With a cold start, idling speed may be consid- erably higher than normal for certain enginetypes. This is done to get the emissions sys-tem up to normal operating temperature asquickly as possible, which minimizes exhaustemissions and protects the environment.
CAUTION
• When starting in cold weather, the auto- matic transmission may shift up at slightlyhigher engine speeds than normal untilthe automatic transmission fluid reachesnormal operating temperature.
• Do not race a cold engine immediatelyafter starting. This could prevent fluidsfrom properly lubricating vital compo-nents in the engine before it has reachedthe proper operating temperature.
• The engine should be idling when thegear selector is moved. Never accelerateuntil the gear is fully engaged. Accelerat-ing rapidly before a gear is properlyengaged could lead to harder wear ofcomponents.
• To help prevent the transmission oil from overheating, select
P or N when idling at
a standstill for prolonged periods of time.

Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
