Engine warm-up
Engines in vehicles driven short distances are subject to abnormally rapid wear because the engine never
reaches normal operating temperature. It is advisable to try to reach normal operating temperature as
soon as possible. This is best achieved by driving with a light foot on the accelerator pedal for a few
minutes after starting, rather than prolonged idling.
pg. 4:5 Starting the engine
Starting and stopping
1 Fasten the seat belt.
WARNING! Before starting, check that the seat is adjusted properly. Make sure the brake pedal can be
depressed completely. Move the seat closer if necessary. Refer to section "Front seats".
2 Apply the parking brake, if not already set. The gear selector ( automatic transmission ) is locked in
the ( P )ark position ( SHIFT LOCK ).
3 Without touching the accelerator pedal , (depress the clutch pedal - manual transmission), turn the
ignition key to the starting position. Allow the starter to operate for up to 5 seconds. Release the key as
soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 m), depress the accelerator pedal halfway and turn the
key to the starting position. Release the accelerator pedal slowly when the engine starts.
4 To release the gear selector from the (P)ark position (automatic transmission) the ignition key must be
in position II and the brake pedal must be depressed.
See page 6:18 for instructions on manually releasing the SHIFTLOCK system.
