CAUTION
If the smell of exhaust is noticed inside the vehicle, open the windows and check
●
that the trunk is closed.
Large amounts of exhaust in the vehicle can cause driver drowsiness and eventu-
ally, death. Have the cause of the problem inspected immediately.
Do not under any circumstances shift the shift lever to P, R or N (automatic trans-
●
mission vehicles) or R (manual transmission vehicles) while the vehicle is moving.
Doing so can cause significant damage to the transmission system and may result
in a loss of vehicle control.
Do not shift the shift lever to N while the vehicle is moving.
●
Doing so may cause the engine brake to not operate properly and lead to an
accident.
Do not turn the engine off while driving.
●
The brake booster system will not operate properly if the engine is not running.
Use engine braking (downshift) to maintain a safe speed when driving down a
●
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (P. 98)
When stopped on an inclined surface, use the brake pedal and parking brake to
●
prevent the vehicle from rolling backward or forward and causing an accident.
Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
●
downshifting, rapidly accelerating, braking or turning.
Do not adjust the position of the steering wheel, the seat, or the inside or outside
●
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
Always check that all passengers' arms, heads or other parts of their bodies are
●
not outside the vehicle, as this may result in death or serious injury.
Do not drive the vehicle off-road.
●
This is not a AWD vehicle designed for real off-road driving. Proceed with all due
caution if it becomes unavoidable to drive off-road.
